Tumbling stem cells? Watch how movement plays a part in their fate
Fan Yang | December 19, 2024
Manish Ayushman, a PhD student in bioengineering, has watched more than a thousand hours of microscopic footage of stem cells in the lab. At first, the cells seemed like they weren’t doing much of anything. But when Ayushman looked a little more closely, he noticed they were moving ever so slightly – turning and pulsing to a languid tempo.
When he sped up the footage, the movements became clearer: Each stem cell appeared to be shimmying and shaking with purpose.
In a paper published Nov. 1 in Nature Materials, Ayushman and Stanford Medicine colleagues described this previously unknown type of cell movement, which they’ve named cell tumbling. Unlike known types of cell movement, such as spreading and migration, which take hours to days, cell tumbling is relatively quick, taking seconds to minutes.

Brain cells remain healthy after a month on the International Space Station, but mature faster than brain cells on Earth
Jeanne Loring | December 17, 2024
Microgravity is known to alter the muscles, bones, the immune system and cognition, but little is known about its specific impact on the brain. To discover how brain cells respond to microgravity, Scripps Research scientists, in collaboration with the New York Stem Cell Foundation, sent tiny clumps of stem-cell derived brain cells called “organoids” to the International Space Station (ISS).
Surprisingly, the organoids were still healthy when they returned from orbit a month later, but the cells had matured faster compared to identical organoids grown on Earth — they were closer to becoming adult neurons and were beginning to show signs of specialization. The results, which could shed light on potential neurological effects of space travel, were published on October 23, 2024, in Stem Cells Translational Medicine.

UTD Researchers Develop At‑Home Sensors To Detect Food & Water Contaminants
Shalini Prasad | December 3, 2024
The recent nationwide alert about E. coli-laced organic carrots is just the latest example that our food safety isn’t guaranteed. Now a research team at UT Dallas is exploring a way that people can do a final check for contaminants—right in their own homes.
From contaminated carrots to harmful hamburger, tainted food has caused sickness and even death for decades—with E. coli-laced organic carrots the latest item to alarm Americans nationwide. Now a research team at the University of Texas at Dallas is developing a tool for consumers to use right in their own homes to add an extra level of food safety.
The researchers—led by Dr. Shalini Prasad, department head of bioengineering at UTD’s Erik Jonsson School of Engineering and Computer Science—is developing sensors that could make it possible for consumers to detect contaminants in food and water “within minutes,” the university said.

Skin Tone Bias Reduces Accuracy in Photoacoustic Imaging for Breast Cancer Detection
Bisi Bell | November 20, 2024
A study from Johns Hopkins University, published in Biophotonics Discovery, examined how skin tone affects the accuracy of photoacoustic imaging (PAI), a technology gaining traction in breast cancer diagnostics, especially in situations where traditional mammography is insufficient. The study shows how image reconstruction methods and laser wavelengths influence the visibility of cancerous targets in patients with diverse skin tones and suggests practical solutions to improve equity in diagnostics.
Photoacoustic imaging is a hybrid imaging technique that combines light and sound. Light pulses are transmitted into the body and absorbed by structures like blood vessels, which then undergo thermal expansion and generate sound waves. Ultrasound detectors capture these waves to create detailed images.

Researchers discover that errors in protein location are a common cause of disease
Anne Carpenter | October 24, 2024
An international team led by researchers at the University of Toronto and the Broad Institute of MIT and Harvard has assembled the first large-scale, publicly available map to show the impact of mutations on where proteins end up in the cell.
The team developed a high-throughput imaging platform to assess the influence of nearly 3,500 mutations on protein location. They found that roughly one in six disease-causing mutations led to proteins ending up in the wrong location in the cell.

Hypoglycemia Controlled by Glucose Responsive Glucagon-Loaded Micelles
Heather Maynard | October 2, 2024
People with diabetes take insulin to lower high blood sugar. However, if glucose levels plunge too low—from taking too much insulin or not eating enough sugar—people can experience hypoglycemia, which can lead to dizziness, cognitive impairment, seizures or comas. Emergency treatment with the hormone glucagon (GCG) may be needed. Researchers at the University of California, Los Angeles (UCLA) have now developed a method to encapsulate glucagon in glucose-responsive micelles that only release the hormone when blood glucose levels become too low. Tests in mice confirmed that the injected nanocapsules activated only when blood sugar levels dropped dangerously low, and quickly restored glucose levels.
Research leads Andrea Hevener, PhD, Heather Maynard, PhD, and colleagues reported on their developments in ACS Central Science, in a paper titled “A Glucose-Responsive Glucagon-Micelle for the Prevention of Hypoglycemia.

Researchers find facemask impacts are leading source of higher severity impacts in professional American football
Kristy Arbogast | September 11, 2024
Nearly one third of concussions in professional American football are due to impacts from the facemask, a part of the helmet that has remained mostly unchanged in the last decade. In a new study presented at the International Research Council on Biomechanics of Injury conference today, researchers used data collected from instrumented mouthpieces worn by players in the National Football League (NFL) that measured head motion and found that facemasks are the most frequent location of impact on a player’s helmet in a subset of high severity impacts. The study findings suggest that facemask enhancements could help protect players and minimize injury risk.
In recent years, there has been a concerted effort to reduce the number of concussions sustained by professional American football players, with one important strategy involving engineering research to redesign helmets to better protect these athletes.
Tiny killers: How autoantibodies attack the heart in lupus patients

Tiny killers: How autoantibodies attack the heart in lupus patients
Gordana Vunjak-Novakovic | August 20, 2024
Columbia team engineers a model of the human heart tissue that demonstrates how autoantibodies directly affect heart disease in lupus patients
Cardiovascular disease is the leading cause of death in patients suffering from lupus, an autoimmune disease in which our immune system attacks our own tissues and organs, the heart, blood, lung, joints, brain, and skin. Lupus myocarditis–inflammation of the heart muscle– can be very serious because the inflammation alters the regularity of the rhythm and strength of the heartbeat. However, the mechanisms underlying this complex disease are poorly understood and difficult to study.
A long-standing question about lupus is why some patients develop myocarditis while others remain unaffected. And why the clinical manifestations of affected patients range so dramatically, from no symptoms at all to severe heart failure. Lupus is characterized by a large number of autoantibodies, immune proteins that mistakenly target a person’s own tissues or organs, with different specificities for various molecules. Like our genes, they may explain why different individuals experience different symptoms.

UD research aims to improve the lives of those with limb loss
John Horne lost his right leg to bone cancer when he was a freshman in high school. This intensely personal experience spawned his career and passion for advocating for those with limb loss. The president of Independence Prosthetics-Orthotics on the University of Delaware’s Science, Technology, and Advanced Research (STAR) Campus has seen prosthetics improve significantly since his limb loss and since he was an undergraduate student at UD, interning at Nemours Children’s Health, where he poured prosthetic molds.
Now, Horne is part of pioneering research led by George W. Laird Professor of Mechanical Engineering Jill Higginson in the Neuromuscular Biomechanics Laboratory along with co-investigators Elisa Arch, associate professor of kinesiology and applied physiology, and Meg Sions, associate professor of physical therapy, in the College of Health Sciences. The study aims to test the potential of fabric-based sensors in monitoring load in individuals with limb loss, a development that could revolutionize the field of prosthetics and significantly improve the lives of those with limb loss.

3D Printing and Citrate Biomaterials Could Allow Dissolvable Stents
Guillermo Ameer | June 14, 2024
Implanted stents have saved countless lives. A tiny metal mesh coil, stents keep arteries open for blood to flow that’s crucial to the body to function after a traumatic angioplasty or cardiac event.
That doesn’t mean they’re a perfected technology.
Stents themselves can also develop plaque due to the systemic nature of the same cardiovascular disease they were implanted to counteract. With cardiovascular disease the leading cause of death globally, according to the World Health Organization, the need for more effective stents has never been greater.

Carolina collaboration yields next-generation medical bandage
Juliane Nguyen | June 13, 2024
From chronic wounds to battlefield triage to heart surgery, this self-sticking bandage is designed to adapt to any body surface, internal or external, creating a bond stronger than current FDA-approved adhesives. The applications of this innovation are detailed in Nature Communications.
“Our patch mimics the skin’s expandability and flexibility, stretching as a person moves,” says principal investigator Juliane Nguyen, professor in the UNC Eshelman School of Pharmacy. “Normal bandages contract in one direction as they expand in another. Ours are designed to expand in both directions, preventing tissue damage and promoting adhesion.”

Microneedle patch holds promise for promoting hair regrowth caused by alopecia areata
Natalie Artzi | June 8, 2024
Alopecia areata (AA) is an autoimmune disease characterized by hair loss, which occurs when T cells of the immune system mistakenly attack hair follicles. To restore control over hyperactive immune cells, investigators from Brigham and Women’s Hospital, a founding member of the Mass General Brigham healthcare system, and MIT developed a cutting-edge approach to deliver T cell regulators directly to sites of hair loss and halt autoimmune activity. Findings, published in Advanced Materials, demonstrated marked and lasting increases in hair regrowth in models of the disease.
Our immune system evolved to safeguard against the overactivation that occurs when it mistakenly attacks our own tissues, as seen in autoimmune conditions. In conditions like AA, the specialized cells known as Regulatory T cells (Tregs) fall short in protecting hair follicles. Current immunosuppressants used in AA target both T cells and Tregs, failing to address the core issue and increasing the risk of disease recurrence once treatment stops. Moreover, systemic immune therapy suppresses the entire immune system, leaving patients vulnerable to infections and malignancies.

Antioxidant gel preserves islet function after pancreas removal
Guillermo Ameer | June 7, 2024
New approach could enable patients to live pain-free without complications of diabetes
Northwestern University researchers have developed a new antioxidant biomaterial that someday could provide much-needed relief to people living with chronic pancreatitis.
The study was published today (June 7) in the journal Science Advances.
Before surgeons remove the pancreas from patients with severe, painful chronic pancreatitis, they first harvest insulin-producing tissue clusters, called islets, and transplant them into the vasculature of the liver. The goal of the transplant is to preserve a patient’s ability to control their own blood-glucose levels without insulin injections.

Study models how ketamine’s molecular action leads to its effects on the brain
Emery Brown | June 4, 2024
New research addresses a gap in understanding how ketamine’s impact on individual neurons leads to pervasive and profound changes in brain network function.
Ketamine, a World Health Organization Essential Medicine, is widely used at varying doses for sedation, pain control, general anesthesia, and as a therapy for treatment-resistant depression. While scientists know its target in brain cells and have observed how it affects brain-wide activity, they haven’t known entirely how the two are connected. A new study by a research team spanning four Boston-area institutions uses computational modeling of previously unappreciated physiological details to fill that gap and offer new insights into how ketamine works.
“This modeling work has helped decipher likely mechanisms through which ketamine produces altered arousal states as well as its therapeutic benefits for treating depression,” says co-senior author Emery N. Brown, the Edward Hood Taplin Professor of Computational Neuroscience and Medical Engineering at The Picower Institute for Learning and Memory at MIT, as well as an anesthesiologist at Massachusetts General Hospital and a professor at Harvard Medical School.

The new research published in the journal Bioelectronic Medicine
One of the major functions of the immune system is to – through antibodies – fight infections. New findings from The Feinstein Institutes for Medical Research bioelectronic medicine scientists show that neurons that help sense pain and prevent illness, called sensory neurons, play an important role in regulating the production of antibodies.
The study published today in the journal Bioelectronic Medicine — an open-access journal and part of BMC Springer Nature — reveals how activating specific nerves using light stimulation, known as optogenetic activation, results in increased antibody responses, and suggests the potential for neuromodulation to improve antibody responses to fight diseases.

Researchers Engineer Yeast to Deliver Drugs, Reduce Inflammation for Possible Inflammatory Bowel Disease Treatment
Juliane Nguyen | May 7, 2024
Inflammatory bowel disease (IBD) is a complex condition that requires individualized care to meet the needs of the patient’s current disease state. With available medications sometimes causing serious side effects or losing their efficacy over time, many researchers have been exploring new, more targeted ways of delivering medications or other beneficial compounds, such as probiotics.
To address pitfalls in IBD treatment and drug delivery, the labs of Juliane Nguyen, PhD, professor and vice chair of pharmacoengineering and molecular pharmaceuticals at the UNC Eshelman School of Pharmacy, and Janelle Arthur, PhD, associate professor of microbiology and immunology at the UNC School of Medicine, have developed a genetically engineered probiotic strain of Saccharomyces boulardii.

Stretchable skin could give caregiving robots a more human touch
Nanshu Lu | May 6, 2024
Newly developed stretchable electronic skin soon might give robots and other devices the same softness and touch sensitivity as human skin. This could prove especially promising for care of the aging, where a soft touch can make a huge difference.
The new stretchable e-skin was developed by researchers at the University of Texas at Austin.
“Much like human skin has to stretch and bend to accommodate our movements, so too does e-skin,” said Nanshu Lu, PhD, a professor in the Cockrell School of Engineering’s Department of Aerospace Engineering and Engineering Mechanics who led the project. “No matter how much our e-skin stretches, the pressure response doesn’t change, and that is a significant achievement.

An electrifying discovery may help doctors deliver more effective gene therapies
Susan Hagness | April 30, 2024
In an effort to improve delivery of costly medical treatments, a team of researchers in electrical engineering at the University of Wisconsin–Madison has developed a stimulating method that could make the human body more receptive to certain gene therapies.
The researchers exposed liver cells to short electric pulses — and those gentle zaps caused the liver cells to take in more than 40 times the amount of gene therapy material compared to cells that were not exposed to pulsed electric fields. The method could help reduce the dosage needed for these treatments, making them much safer and more affordable. The research appears April 30 in the journal PLOS ONE.

Synthetic Plugs Offer Alternative to Total Knee Replacements
Melissa Grunlan | April 30, 2024
Dr. Melissa Grunlan is developing synthetic plugs for patients suffering from chronic knee pain or disabilities that would avoid total knee replacements.
Osteochondral defects (OCDs) can cause damage to cartilage and underlying bone, leading to chronic pain and loss of joint function. Depending on the extent of damage, individuals must undergo surgical treatment, the most extensive being total knee replacement, which over 800,000 Americans undergo each year.
Dr. Melissa Grunlan, professor in the Department of Biomedical Engineering at Texas A&M University, received a grant from the National Institute of Arthritis and Musculoskeletal and Skin Disease, a suborganization of the National Institutes of Health, to develop synthetic cartilage-capped regenerative osteochondral plugs (CC-ROPs) — a potential off-the-shelf surgical device to treat OCDs and avoid total knee replacement.

Circadian rhythms can influence drugs’ effectiveness
Sangeeta Bhatia | April 24, 2024
MIT researchers find circadian variations in liver function play an important role in how drugs are broken down in the body.
Giving drugs at different times of day could significantly affect how they are metabolized in the liver, according to a new study from MIT.
Using tiny, engineered livers derived from cells from human donors, the researchers found that many genes involved in drug metabolism are under circadian control. These circadian variations affect how much of a drug is available and how effectively the body can break it down. For example, they found that enzymes that break down Tylenol and other drugs are more abundant at certain times of day.

Engineered Peptides Stimulate Antitumor Immune Responses in Mice
Betty Kim | April 22, 2024
Researchers have designed a new method for developing immunotherapy drugs using engineered peptides to elicit a natural immune response inside the body. More specifically, they showed, in antigen presenting cells, that “the hydrophobicity, electrostatic charge, and secondary conformation of helical polypeptides can be optimized to stimulate innate immune pathways via endoplasmic reticulum stress.”
In preclinical models of locally advanced and metastatic breast cancer, this method improved tumor control and prolonged survival, both as a monotherapy and in combination with immune checkpoint inhibitors.

The stretchy, wireless sensor could keep patients with bladder issues informed in real-time.
For people dealing with spina bifida, paralysis, and various bladder diseases, determining when to take a bathroom break can be an issue. To help ease the frequent stress, researchers at Northwestern University have designed a sensor array that attaches to the bladder’s exterior wall, enabling it to detect its fullness in real time. Using embedded Bluetooth technology, the device then transmits its data to a smartphone app, allowing users to monitor their bodily functions without far less discomfort and guesswork.
The new tool, detailed in a study published today in the Proceedings of the National Academy of Sciences (PNAS), isn’t only meant to prevent incontinence issues. Lacking an ability to feel bladder fullness extends far beyond the obvious inconveniences—for millions of Americans dealing with bladder dysfunctions, not knowing when to go to the bathroom can cause additional organ damage such as regular infections and kidney damage. To combat these issues, the new medical device mirrors the bladder’s own elasticity.

A lung-mimicking sealant helps repair surgical leaks
Gordana Vunjak-Novakovic | March 12, 2024
A superior surgical sealant mimics the structural and mechanical properties of lung tissue to repair air leaks after surgery.
A new sealant meant to mimic lung tissue has been shown to rapidly cork air leaks following surgery. Moreover, the protein-like molecules within the sealant were found to potentially help with wound repair.
“Our lung-mimetic sealant is designed with a structure similar to that of the healthy lung, allowing the sealant to deform in a similar way as the breathing lung,” explained Meghan Pinezich, researcher at Columbia University in the US, and first author on the study, in an email.

How AI-powered handheld devices are boosting disease diagnostics – from cancer to dermatology
Irving Bigio | March 12, 2024
In the past, artificial intelligence (AI) in healthcare was mostly in the hands of specialists — experts in marrying supercomputers to hefty hospital devices. Now, thanks to a new breed of compact, handheld AI-assisted disease-detection devices, that is changing. Healthcare AI is increasingly in the hands (and the pockets) of non-specialists.
Lightweight, battery-powered handheld healthcare AI devices made a splash in January 2024 with the arrival of a portable device for detecting skin cancer. Approved for marketing by the US Food and Drug Administration (FDA) under the brand name DermaSensor, the device looks like an oversized cellphone. It is approved for use solely by physicians, and only in patients over 40 years of age, to help in the evaluation of skin lesions suggestive of three types of skin cancer: melanoma, basal cell carcinoma and squamous cell carcinoma.

Metal-Organic Nanoparticles Enable Better Vaccine Delivery, Stronger Immune Response
Ana Jaklenec | March 6, 2024
Scientists from the Massachusetts Institute of Technology (MIT) and elsewhere have published a paper in Science Advances that describes a type of nanoparticle for delivering vaccines called a metal organic framework (MOF) that can potentially provoke a strong immune response at lower doses. The paper is titled “Zeolitic Imidazolate Frameworks Activate Endosomal Toll-like Receptors and Potentiate Immunogenicity of SARS-CoV-2 Spike Protein Trimer.”
In the study, which was done in mice, the researchers showed that the MOF successfully encapsulated and delivered part of the SARS-CoV-2 spike protein while simultaneously acting as an adjuvant once it broke down inside cells. More work is needed to ensure that the particles can be used safely in human vaccines, but these early results are promising.

Researchers at the University of California, San Francisco (UCSF) recently developed an AI algorithm that can identify patients at risk for developing Alzheimer’s disease up to seven years in advance, according to a study published last week in Nature Aging.
The researchers reported that their AI models predicted Alzheimer’s disease up to seven years in advance with 72% accuracy.
The predictive capabilities of artificial intelligence (AI) machine learning are enabling disease prediction and accelerating precision medicine in an effort to improve patient outcomes. Alzheimer’s disease (AD), an incurable neurodegenerative disease, is the most common form of dementia.

DNA Melting Curves Could Speed Blood-Borne Pathogen Detection
Stephanie Fraley | February 21, 2024
Scientists from the University of California, San Diego (UCSD), and elsewhere have described a method of detecting blood-borne pathogens faster and more accurately than traditional blood cultures. The method, called digital DNA melting analysis, produces results in under six hours, much shorter than traditional cultures which can require 15 hours to several days depending on the pathogen.
Details of the method and results from a clinical pilot using blood samples from pediatric patients are provided in the Journal of Molecular Diagnostics in a paper titled, “Universal digital high resolution melt analysis for the diagnosis of bacteremia.” Results from the pilot study showed that their DNA melting approach matched results of blood cultures collected for sepsis testing. They were also able to quantify how much of the pathogen was present in the samples using DNA melting.

Metastatic breast cancer treatments have aided decline in deaths, Stanford Medicine-led study finds
Sylvia Plevritis | January 17, 2024
Deaths from breast cancer dropped 58% between 1975 and 2019 due to a combination of screening mammography and improvements in treatment, according to a new multicenter study led by Stanford Medicine clinicians and biomedical data scientists.
Nearly one-third of the decrease (29%) is due to advances in treating metastatic breast cancer —a form that has spread to other areas of in the body and is known as stage 4 breast cancer or recurrent cancer. Although these advanced cancers are not considered curable, women with metastatic disease are living longer than ever.
The analysis helps cancer researchers assess where to focus future efforts and resources.

Inhalable sensors could enable early lung cancer detection
Sangeeta Bhatia | January 5, 2024
The diagnostic, which requires only a simple urine test to read the results, could make lung cancer screening more accessible worldwide.
Using a new technology developed at MIT, diagnosing lung cancer could become as easy as inhaling nanoparticle sensors and then taking a urine test that reveals whether a tumor is present.
The new diagnostic is based on nanosensors that can be delivered by an inhaler or a nebulizer. If the sensors encounter cancer-linked proteins in the lungs, they produce a signal that accumulates in the urine, where it can be detected with a simple paper test strip.

Low-dose CT screening can catch lung cancer early – but most people overlook it
Denise Aberle | November 8, 2023
CT was shown to be the first and most effective way of reducing lung cancer mortality,’ says UCLA Health’s Dr. Denise Aberle.
Most people at greatest risk of lung cancer are overlooking a non-invasive screening that can detect cases early, when treatment can best save lives.
November marks Lung Cancer Awareness Month and UCLA Health lung cancer experts are working to spread the word about the importance of low-dose computed tomography (LDCT) of the chest. The annual scan is recommended for people with a long-term history of smoking, as well as other criteria, including age.
The screening is designed to find asymptomatic cancers when they are most treatable with surgery or radiation. It also allows doctors to monitor any suspicious findings over time.
Anesthesia technology precisely controls unconsciousness in animal tests

Anesthesia technology precisely controls unconsciousness in animal tests
Emery Brown | November 7, 2023
An advanced closed-loop anesthesia delivery system that monitors brain state to tailor propofol dose and achieve exactly the desired level of unconsciousness could reduce post-op side effects.
If anesthesiologists had a rigorous means to manage dosing, they could deliver less medicine, maintaining exactly the right depth of unconsciousness while reducing postoperative cognitive side effects in vulnerable groups like the elderly. But with myriad responsibilities for keeping anesthetized patients alive and stable as well as maintaining their profoundly unconscious state, anesthesiologists don’t have the time without the technology.
To solve the problem, researchers at The Picower Institute for Learning and Memory at MIT and Massachusetts General Hospital (MGH) have invented a closed-loop system based on brain state monitoring that accurately controls unconsciousness by automating doses of the anesthetic drug propofol every 20 seconds.

Advancing ultrasound microvessel imaging and AI to improve cancer detection
Azra Alizad | October 21, 2023
Ultrasound—a technology that uses sound waves to produce an image—is commonly used to monitor the development of a baby as it grows inside its mother. But ultrasound imaging also can be used to investigate suspicious masses of tissue and nodules that may be cancerous.
Tumors consist not only of cancer cells but also a matrix of small blood vessels, or microvessels, that cannot be seen in the images produced by conventional ultrasound machines. To solve this problem, physician-scientist Azra Alizad, M.D., and biomedical engineering scientist Mostafa Fatemi, Ph.D., teamed up at Mayo Clinic to design and study a tool that may improve the resolution of ultrasound imaging.

Immunotherapy Response in Glioblastoma Induced by mRNA Delivered by Extracellular Vesicles
Betty Kim | October 20, 2023
Investigators at the University of Texas MD Anderson Cancer Center has developed a potentially groundbreaking method for enhancing immunotherapy responses in glioblastoma by using extracellular vesicles loaded with messenger RNA (mRNA). This new approach, detailed in Nature Communications, has solved some of the hurdles faced by mRNA-based therapy approaches for cancer and could lead to wider use of these therapies across a range of hard-to-treat tumor types.
The new approach for mRNA delivery builds on research from a team at MD Anderson led by Betty Kim, MD, PhD, and Wen Jiang, MD, PhD, who developed a novel method earlier this year of loading mRNA into extracellular vesicles and demonstrates the anti-tumor potential of this method of therapeutic delivery. Researchers have known for some time the therapeutic potential of mRNA to fight both infectious diseases and cancer. But methods to deliver it accurately to where it is needed has been a challenge, with various other potential delivery method studied previously including via lipid polymeric nanoparticles.

Curbing Lung Cancer Metastasis with Nanoparticle Vaccine
Nicole Steinmetz | October 11, 2023
Scientists at the University of California (UC), San Diego, have developed an experimental vaccine that could curb the spread of metastatic cancers to the lungs. The key ingredients of the vaccine are nanoparticles that have been engineered to target a protein known to play a central role in cancer growth and spread. The vaccine significantly reduced the spread of metastatic breast and skin cancers to the lungs in mice. It also improved the survival rate in mice with metastatic breast cancer after surgical removal of the primary tumor.
The findings were published in the Proceedings of the National Academy of Sciences in an article titled, “Viral nanoparticle vaccines against S100A9 reduce lung tumor seeding and metastasis.”
Restoring nerve-muscle connections boosts strength of aging mice, Stanford Medicine study finds

Restoring nerve-muscle connections boosts strength of aging mice, Stanford Medicine study finds
Helen Blau | October 11, 2023
A drug that boosts strength in injured or aging mice restores connections between nerves and muscle and suggests ways to combat weakness in humans due to aging, injury or disease.
A small molecule previously shown to enhance strength in injured or old laboratory mice does so by restoring lost connections between nerves and muscle fibers, Stanford Medicine researchers have found.
The molecule blocks the activity of an aging-associated enzyme, or gerozyme, called 15-PGDH that naturally increases in muscles as they age. The study showed that levels of the gerozyme increase in muscles after nerve damage and that it is prevalent in muscle fibers of people with neuromuscular diseases.
The research is the first to show that damaged motor neurons — nerves connecting the spinal cord to muscles — can be induced to regenerate in response to a drug treatment and that lost strength and muscle mass can be at least partially regained. It suggests that, if similar results are seen in humans, the drug may one day be used to prevent muscle loss of muscle strength due to aging or disease or to hasten recovery from injury.

Tumor-destroying sound waves receive FDA approval for liver treatment in humans
Zhen Xu | October 9, 2023
The U.S. Food and Drug Administration has approved the use of sound waves to break down tumors—a technique called histotripsy—in humans for liver treatment.
Pioneered at the University of Michigan, histotripsy offers a promising alternative to cancer treatments such as surgery, radiation and chemotherapy, which often have significant side effects. Today, FDA officials awarded clearance to HistoSonics, a company co-founded in 2009 by U-M engineers and doctors for the use of histotripsy to destroy targeted liver tissue.
A human trial underway since 2021 at the U-M Rogel Cancer Center and other locations has treated patients with primary and metastatic liver tumors via histotripsy, demonstrating the technology’s ability to meet the testing’s primary effectiveness and safety targets.

The cactus chemist: Dr. Norma Alcantar
Norma Alcantar | September 5, 2023
Among the typical things you’d expect to find in a chemical engineer’s office — honorary awards, patent plaques, and books like “Environmental Analytical Chemistry” and “Introducing Chemical Engineering Thermodynamics” — Dr. Norma Alcantar’s office at the University of South Florida (USF) also showcases her love of life and teaching with books like “Intentional Integrity,” a coffee mug that reads “the influence of a good teacher can never be erased,” and a decorative plaque that reads “It’s All Gonna Be Fine.”
But hidden between the intellectual and inspirational materials, two sets of objects stand out: a series of cacti and owl collectibles. To the uninitiated, they appear to be whimsical office décor, but to those who know Alcantar, the folklore wisdom of the owl and the hardy, but elegantly designed cacti plant represent the tapestry of her life and career.

Engineered Proteins Take On Cancer’s Epigenome
Karmella Haynes | August 24, 2023
In addition to characterizing the genetic basis for different cancers, scientists are increasingly interested in the role of the epigenome in tumor development, and possible therapies that can target genes repressed by chemically modifying chromatin in cancer.
Part of what makes the epigenome an attractive target is the possibility of hitting a system of proteins involved in gene expression programming rather than a single target, according to Karmella Haynes, PhD, an assistant professor of biomedical engineering at Emory University. She and a team of scientists from Emory University and Georgia Institute of Technology have developed another potential approach for reactivating repressed tumor suppressor genes that could ultimately have implications for how solid tumors like triple-negative breast cancer (TNBC) are treated.

Transforming flies into degradable plastics
Karen Wooley | August 14, 2023
Imagine using insects as a source of chemicals to make plastics that can biodegrade later — with the help of that very same type of bug. That concept is closer to reality than you might expect. Today, researchers will describe their progress to date, including isolation and purification of insect-derived chemicals and their conversion into functional bioplastics.
The researchers will present their results at the fall meeting of the American Chemical Society (ACS). ACS Fall 2023 is a hybrid meeting being held virtually and in-person Aug. 13–17, and features about 12,000 presentations on a wide range of science topics.
“For 20 years, my group has been developing methods to transform natural products — such as glucose obtained from sugar cane or trees — into degradable, digestible polymers that don’t persist in the environment,” said Karen Wooley, PhD, the project’s principal investigator.

Deep learning unlocks personalised cancer therapy
Rachel Karchin | August 14, 2023
Engineers and cancer researchers have harnessed the power of machine learning technology to predict immune-boosting proteins.
Machine learning technology developed by a team of Johns Hopkins engineers and cancer researchers can accurately predict cancer-related protein fragments that may trigger an immune system response.
If validated in clinical trials, the technology could help scientists overcome a major hurdle to developing personalised immunotherapies and vaccines.
In a new study, investigators from Johns Hopkins Biomedical Engineering, the Johns Hopkins Institute for Computational Medicine, the Johns Hopkins Kimmel Cancer Center and the Bloomberg~Kimmel Institute for Cancer Immunotherapy show that their deep learning method, called BigMHC, can identify protein fragments on cancer cells that elicit a tumour cell-killing immune response, an essential step in understanding response to immunotherapy and in developing personalised cancer therapies.

New DNA Identification Approach Could Improve Monitoring for Chronic Diseases
Shana Kelley | July 26, 2023
Investigators led by Shana Kelley, PhD, the Neena B. Schwartz Professor of Chemistry, Biomedical Engineering, and of Biochemistry and Molecular Genetics, have developed a novel approach for identifying sequences of artificial DNA with differing levels of binding to other small molecules.
The approach, detailed in a study published in Nature Chemistry, could help improve the efficiency of diagnostic monitoring for patients with chronic diseases.
Aptamers are sequences of artificial DNA that selectively bind to other small molecules such as peptides, carbohydrates and foreign pathogens. Aptamers can be used for therapeutic purposes in the same way as monoclonal antibodies, and have been used for pathogen and cancer recognition as well as stem cell markers.

Jeanne Loring | July 19, 2023
The discovery by scientists from Scripps Research and Cardiff University paves the way for clinical trials that use patients’ own cells to treat Parkinson’s disease
Scientists from Scripps Research and Cardiff University made key discoveries in support of a new stem cell-based therapy for Parkinson’s disease. The approach, called an autologous therapy, uses induced pluripotent stem cells (iPSCs)—made from a patient’s own skin or blood cells—to replace the neurons in the brain that are lost in Parkinson’s. Transplants of a person’s own cells eliminates the need for immunosuppression.
In a new study, the researchers used iPSCs made from the skin cells of two people with Parkinson’s disease to make young neurons that were successfully transplanted into a rat model with the disease. They used the animal model to pinpoint exactly at what stage of development the iPSC-derived neurons should be transplanted to become mature neurons that can reverse signs of disease in the rat brain.

Study finds tracking brain waves could reduce post-op complications
Emery Brown | July 17, 2023
Distinctive EEG patterns indicate when a patient’s state of unconsciousness under general anesthesia is more profound than necessary.
When patients undergo general anesthesia, their brain activity often slows down as they sink into unconsciousness. Higher doses of anesthetic drugs can induce an even deeper state of unconsciousness known as burst suppression, which is associated with cognitive impairments after the patient wakes up.
A new study from MIT, in which the researchers analyzed the EEG patterns of patients under anesthesia, has revealed brain wave signatures that could help anesthesiologists determine when patients are transitioning into that deeper state of unconsciousness. This could enable them to prevent patients from falling into that state, reducing the risk of postoperative brain dysfunction.

Julie Sutcliffe | June 28, 2023
New research is offering some hope in the fight against pancreatic cancer.
The answer is nuclear medicine. And the power to find cancer and deliver therapy all at the same time. Theranostics, combining therapy and diagnostics, is a promising approach to cancer treatment.
While some people fear the idea of using radioactive isotopes as a therapy in the body, Julie Sutcliffe PhD. knows the power for good.
“You have a molecule, same molecule with a different piece of radioactivity on it, so one is for imaging for diagnostics, one is for therapy for treatment,” she said. “So theranostics combine the two words together.”

Rice engineers show low-cost, point-of-care platform is effective for HPV testing
Rice University bioengineers have demonstrated a low-cost, point-of-care DNA test for HPV infections that could make cervical cancer screening more accessible in low- and middle-income countries where the disease kills more than 300,000 women each year.
HPV, a family of viruses, infects nearly everyone at some point in their lives, often without symptoms. But more than a dozen types of HPV can cause persistent infections that result in cervical cancer, which is preventable and curable if it is detected early and managed effectively.
Nine engineers from the laboratory of Rice Professor Rebecca Richards-Kortum spent more than two years developing a DNA testing platform that combines two technologies, isothermal DNA amplification and lateral flow detection, in a way that greatly simplifies the equipment needs and procedures for testing.

Designing Surfaces to Improve Bone Grafts
Guillermo Ameer | June 12, 2023
The field of bone implants has taken incredible strides thanks to technological innovations that allow for stronger grafts that are easier to install.
Yet even with these advances, there are still risks involved in such procedures. Implants can be loosened following operations, for example, which can lead to costly surgical revisions that lengthen the recovery process for patients.
New research from an interdisciplinary team from Northwestern Engineering’s Center for Advanced Regenerative Engineering (CARE) and Center for Physical Genomics and Engineering (CPGE) could reduce the likelihood of these painful, expensive complications.

How the combination of advanced ultrasound and AI could upgrade cancer diagnostics
Azra Alizad | June 5, 2023
Researchers have shown that an automated cancer diagnostic method, which pairs cutting-edge ultrasound techniques with artificial intelligence, can accurately diagnose thyroid cancer, of which there are more than 40,000 new cases every year.
The method—deemed high-definition microvasculature imaging, or HDMI—noninvasively captures images of the tiny vessels within tumors and, based on the vessel features, automatically classifies the masses. Researchers at the Mayo Clinic College of Medicine and Science, who developed the technique, tested it on 92 patients with thyroid tumors, finding that the method could distinguish if the growths were cancerous with 89% accuracy. In a study published in the journal Cancers, the authors suggest that HDMI could potentially resolve a long-standing diagnostic challenge of assessing thyroid tumors in the clinic.

Healing Big Broken Bones With a Small Molecule
Cato Laurencin | May 24, 2023
Repairing severely damaged bones is a challenge—especially the long bones of the arms and legs. Now, UConn Health scientists describe a new method in the 22 May issue of PNAS that can promote regrowth of long bones more affordably and with fewer side effects than other techniques.
Cleanly broken bones often heal without problems. But bones with smashed or missing sections are much more difficult to regenerate. Grafting across the gaps using bone from elsewhere is one way to fix them, and about 500,000 bone grafts are done in the US every year. But bone grafts alone don’t always work, and they’re quite costly. Recently, orthopedic surgeons have begun treating difficult breaks with specific human proteins that encourage bone growth, both alone and paired with grafts or scaffolds. They are used to encourage bone regrowth in spinal fusion surgeries, for example.

CRISPR-Cas-amplified urinary biomarkers for multiplexed and portable cancer diagnostics
Sangeeta Bhatia | April 24, 2023
Synthetic biomarkers, bioengineered sensors that generate molecular reporters in diseased microenvironments, represent an emerging paradigm in precision diagnostics. Despite the utility of DNA barcodes as a multiplexing tool, their susceptibility to nucleases in vivo has limited their utility. Here we exploit chemically stabilized nucleic acids to multiplex synthetic biomarkers and produce diagnostic signals in biofluids that can be ‘read out’ via CRISPR nucleases. The strategy relies on microenvironmental endopeptidase to trigger the release of nucleic acid barcodes and polymerase-amplification-free, CRISPR-Cas-mediated barcode detection in unprocessed urine. Our data suggest that DNA-encoded nanosensors can non-invasively detect and differentiate disease states in transplanted and autochthonous murine cancer models. We also demonstrate that CRISPR-Cas amplification can be harnessed to convert the readout to a point-of-care paper diagnostic tool. Finally, we employ a microfluidic platform for densely multiplexed, CRISPR-mediated DNA barcode readout that can potentially evaluate complex human diseases rapidly and guide therapeutic decisions.

Python-based compiler achieves orders-of-magnitude speedups
Bonnie Berger | March 14, 2023
Codon compiles Python code to run more efficiently and effectively while allowing for customization and adaptation to various domains.
In 2018, the Economist published an in-depth piece on the programming language Python. “In the past 12 months,” the article said, “Google users in America have searched for Python more often than for Kim Kardashian.” Reality TV stars, be wary.
The high-level language has earned its popularity, too, with legions of users flocking daily to the language for its ease of use due in part to its simple and easy-to-learn syntax. This led researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) and elsewhere to make a tool to help run Python code more efficiently and effectively while allowing for customization and adaptation to different needs and contexts. The compiler, which is a software tool that translates source code into machine code that can be executed by a computer’s processor, lets developers create new domain-specific languages (DSLs) within Python — which is typically orders of magnitude slower than languages like C or C++ — while still getting the performance benefits of those other languages.

‘Groundbreaking’ Soil Sensors From UT Dallas Bioengineers Could Help Combat Climate Change, Food Insecurity
Shalini Prasad | March 9, 2023
“This is the equivalent of having a wearable health sensor on your body that tells you in real time what’s happening. Think of it as a wearable for the soil,” Dr. Shalini Prasad said.
Soil quality isn’t just a concern for farmers and policymakers—it also matters on a personal level. The health of our soil affects everything from the food we eat to the air we breathe. But thanks to bioengineers at UT Dallas, new soil sensors could help improve soil productivity on a global scale.
Bioengineers at the University of Texas at Dallas have developed sensors that monitor multiple soil parameters, including total soil carbon, to provide farmers with accurate, real-time, continuous data to improve soil health and productivity.

AI Model Provides Insights into Long-Term Traumatic Brain Injury Risk
Ellen Kuhl | March 7, 2023
A new AI model may signal a ‘paradigm shift’ in traumatic brain injury research by more accurately modeling the tissue deformations that lead to brain damage.
Stanford University researchers are leveraging artificial intelligence (AI) to help identify which computational models perform best at modeling mechanical stress on the brain, which may help drive insights into why some traumatic brain injuries (TBIs) lead to long-term brain damage while others do not.
The press release states that the ability to model the mechanical forces causing the compression, stretching, twisting, and other deformations of brain tissue that lead to brain damage is critical to understanding TBI. This modeling could help researchers understand why some TBIs lead to lasting brain damage and some don’t.

First Transient Electronic Bandage Speeds Healing by 30 Percent
Guillermo Ameer | February 22, 2023
Northwestern Engineering researchers have developed a first-of-its-kind small, flexible, stretchable bandage that accelerates healing by delivering electrotherapy directly to the wound site.
In an animal study, the new bandage healed diabetic ulcers 30 percent faster than in mice without the bandage.
The bandage also actively monitors the healing process and then harmlessly dissolves — electrodes and all — into the body after it is no longer needed. The new device could provide a powerful tool for patients with diabetes, whose ulcers can lead to various complications, including amputated limbs or even death.

Disrupted flow of brain fluid may underlie neurodevelopmental disorders
Samuel Achilefu | February 9, 2023
The brain floats in a sea of fluid that cushions it against injury, supplies it with nutrients and carries away waste. Disruptions to the normal ebb and flow of the fluid have been linked to neurological conditions including Alzheimer’s disease and hydrocephalus, a disorder involving excess fluid around the brain.
Researchers at Washington University School of Medicine in St. Louis created a new technique for tracking circulation patterns of fluid through the brain and discovered, in rodents, that it flows to areas critical for normal brain development and function. Further, the scientists found that circulation appears abnormal in young rats with hydrocephalus, a condition associated with cognitive deficits in children.

How sound waves trigger immune responses to cancer in mice
Zhen Xu | January 31, 2023
When noninvasive sound waves break apart tumors, they trigger an immune response in mice. By breaking down the cell wall “cloak,” the treatment exposes cancer cell markers that had previously been hidden from the body’s defenses, researchers at the University of Michigan have shown.
The technique developed at Michigan, known as histotripsy, offers a two-prong approach to attacking cancers: the physical destruction of tumors via sound waves and the kickstarting of the body’s immune response. It could potentially offer medical professionals a treatment option for patients without the harmful side effects of radiation and chemotherapy.

How to make hydrogels more injectable
Jennifer Lewis | January 31, 2023
Gel-like materials that can be injected into the body hold great potential to heal injured tissues or manufacture entirely new tissues. Many researchers are working to develop these hydrogels for biomedical uses, but so far very few have made it into the clinic.
To help guide in the development of such materials, which are made from microscale building blocks akin to squishy LEGOs, MIT and Harvard University researchers have created a set of computational models to predict the material’s structure, mechanical properties, and functional performance outcomes. The researchers hope that their new framework could make it easier to design materials that can be injected for different types of applications, which until now has been mainly a trial-and-error process.

Accurate integrated imaging and projection system for oral cancer diagnosis
Rebecca Richards-Kortum | January 19, 2023
Oral cancer is a globally prevalent disease with an astonishingly low five-year survival rate of less than 50%. A key factor for its poor prognosis is delayed diagnosis resulting in more late-stage oral cancers. At these later stages, treatment becomes less effective and harsher on the body. Hence, many scientists aim to develop and improve diagnostic techniques for the early detection of oral cancer. At present, the gold standard for the diagnosis of most oral cancers is biopsy of suspicious oral lesions and pathologic analysis of the extracted small amounts of tissue. However, it is extremely important that clinicians biopsy the areas within the abnormal lesion with the worst disease. Currently, the decision whether or not to perform a biopsy, and the optimal biopsy site, are based on clinical examination, which greatly depends upon the experience of the examining clinician. To help identify high-risk regions, clinicians can also use commercially available imaging techniques based on autofluorescence to detect abnormal tissue at the macroscopic level, although current autofluorescence technologies suffer from low specificity for neoplastic disease.

Mechanism Behind Osteoarthritis Could Lead to New Treatments
Fabrisia Ambrosio | January 10, 2023
Researchers in the United States and Japan have discovered a new mechanism that links age-related cartilage tissue stiffening with the repression of a key protein associated with longevity. These findings enhance the understanding of mechanisms that lead to the deterioration of joints that causes osteoarthritis, according to the authors of a new study, published January 10th in Nature Communications.
In the study, researchers showed that increased stiffening of the extracellular matrix – a network of proteins and other molecules that surround and support tissues in the body – led to a decrease in a so-called “longevity protein” called Klotho (α-Klotho) in knee cartilage brought about by epigenetic changes. This Klotho decrease then damaged the cells in healthy cartilage called chondrocytes. Conversely, exposing aged chondrocytes to a softer extracellular matrix restored the knee cartilage to a more youthful state.

Finding the “Sweet Spot” for Indoor Humidity May Help to Reduce COVID-19 Transmission
Lydia Bourouiba | November 18, 2022
As friends and families are beginning to plan holiday gatherings, a new study found that raising the humidity level could be another mitigation method to reduce COVID-19. That sweet spot looks to be between 40% and 60% humidity.
Researchers from Massachusetts Institute of Technology (MIT) combined population-based COVID-19 data with meteorologic measurements from 121 countries collected between January and August 2020 (J R Soc Interface 2022;19[196]:20210865). Countries included had reported at least 50 COVID-19–related deaths, indicating at least one outbreak had occurred. The researchers processed the epidemiological data while accounting for bias, and developed a computational workflow to estimate indoor conditions based on outdoor weather data and standard indoor comfort conditions.

Vanderbilt study finds that diabetes may hasten breast cancer tumor growth and stiffness
Cynthia Reinhart-King | November 18, 2022
While diabetes is already associated with an increased risk of developing breast cancer, a new Vanderbilt study published in Science Advances on November 18 indicates that presence of the disease may increase tumor growth and stiffness.
Researchers also found that diabetes treatments could reduce the tumor growth and stiffness to levels comparable with non-diabetic ones. The research was led by Cynthia Reinhart-King, Cornelius Vanderbilt Professor of Engineering and University Distinguished Professor. Vanderbilt Ph.D. student Wenjun Wang, a current member of Reinhart-King’s cellular mechanics lab, and Lauren Hapach, PhD’21, a former lab member, were co-authors.

Are Covid-19 “comas” signs of a protective hibernation state?
Emery Brown | November 18, 2022
Scientists hypothesize that, as in a hibernating turtle, the brain under sedation and deprived of oxygen may assume a protective state.
Many Covid-19 patients who have been treated for weeks or months with mechanical ventilation have been slow to regain consciousness even after being taken off sedation. A new article in the Proceedings of the National Academy of Sciences offers the hypothesis that this peculiar response could be the effect of a hibernation-like state invoked by the brain to protect cells from injury when oxygen is scarce.
A very similar kind of state, characterized by the same signature change of brain rhythms, is not only observed in cardiac arrest patients treated by chilling their body temperature, a method called “hypothermia,” but also by the painted turtle, which has evolved a form of self-sedation to contend with long periods of oxygen deprivation, or “anoxia,” when it overwinters underwater.
Old mice regain leg strength after antibody treatment, Stanford Medicine researchers find

Old mice regain leg strength after antibody treatment, Stanford Medicine researchers find
Helen Blau | November 15, 2022
Muscle stem cells, the cells in muscle fibers that generate new muscle cells after injury or exercise, lose their potency with age. But a study by researchers at Stanford Medicine shows that old mice regain the leg muscle strength of younger animals after receiving an antibody treatment that targets a pathway mediated by a molecule called CD47.
The findings are surprising because CD47, billed as the “don’t eat me” molecule, is better known as a target for cancer immunotherapy than for muscle regeneration. It peppers the surface of many cancer cells, protecting them from immune cells that patrol the body to root out and engulf dysfunctional or abnormal cells. Now it seems old muscle stem cells may use a similar approach to avoid being culled by the immune system.
