This groundbreaking biomaterial heals tissues from the inside out: The material can be injected intravenously and has potential application in heart attacks, traumatic brain injury and more

A new biomaterial that can be injected intravenously, reduces inflammation in tissue and promotes cell and tissue repair. The biomaterial was tested and proven effective in treating tissue damage caused by heart attacks in both rodent and large animal models. Researchers also provided proof of concept in a rodent model…

New method to control electron spin paves the way for efficient quantum computers: The method, developed by University of Rochester scientists, overcomes the limitations of electron spin resonance

Quantum science has the potential to revolutionize modern technology with more efficient computers, communication, and sensing devices. Challenges remain in achieving these technological goals, however, including how to precisely manipulate information in quantum systems. In a paper published in Nature Physics, a group of researchers from the University of Rochester,…

Marburg vaccine shows promising results in first-in-human study

A newly published paper in The Lancet shows that an experimental vaccine against Marburg virus (MARV) was safe and induced an immune response in a small, first-in-human clinical trial. The vaccine, developed by researchers at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of…

Sports-related sudden cardiac arrest is rare in older adults

The annual incidence of sports-related sudden cardiac arrest in older adults is rare: 2 to 3 cases per 100,000 people. Of the 4,078 total sudden cardiac arrest cases studied in people 65 and older, 77 (1.9%) occurred during or following an exercise activity, such as cycling, gym workout, running, or…

Machine learning identifies drugs that could potentially help smokers quit

Medications like dextromethorphan, used to treat coughs caused by cold and flu, could potentially be repurposed to help people quit smoking cigarettes, according to a study by Penn State College of Medicine and University of Minnesota researchers. They developed a novel machine learning method, where computer programs analyze data sets…

Will machine learning help us find extraterrestrial life? Applying deep learning techniques to previously analyzed datasets revealed undetected signals of interest

When pondering the probability of discovering technologically advanced extraterrestrial life, the question that often arises is, “if they’re out there, why haven’t we found them yet?” And often, the response is that we have only searched a tiny portion of the galaxy. Further, algorithms developed decades ago for the earliest…

Researchers make recommendations for diversifying syllabi in higher education

Over the past decade, there has been a growing awareness that environmental and life science fields need to diversify their teaching syllabi. Many have suggested highlighting Black women scholars, hidden figures in the fields, and elevating Black, Indigenous, and People of Color scholars. However, faculty sometimes worry that their solitary…

Under pressure: Breakthrough new material solves problem of wearable sensors: Team develops all-fabric pressure sensor that works even when the pressure is pushing down on you

A team of researchers, led by Trisha L. Andrew, professor of chemistry and chemical engineering at the University of Massachusetts Amherst, recently announced that they have synthesized a new material that solves one of the most difficult problems in the quest to create wearable, unobtrusive sensitive sensors: the problem of…

Tweezers untangle chemotherapeutic’s impact on DNA

New Cornell research is providing a fresh view into the ways a common chemotherapy agent, etoposide, stalls and poisons the essential enzymes that allow cancer cells to flourish. The findings, from the lab of Michelle Wang, the James Gilbert White Distinguished Professor of the Physical Sciences and Howard Hughes Medical…

This budget airline is making record profits | CNN Business

London CNN  —  Ryanair expects it will be able to charge higher prices for flights over Easter and the summer, thanks to strong demand from American and Asian tourists and less competition from rivals. The low-cost European carrier told customers in an earnings statement on Monday to “book early” before…

Superconductivity switches on and off in ‘magic-angle’ graphene: A quick electric pulse completely flips the material’s electronic properties, opening a route to ultrafast, brain-inspired, superconducting electronics.

With some careful twisting and stacking, MIT physicists have revealed a new and exotic property in “magic-angle” graphene: superconductivity that can be turned on and off with an electric pulse, much like a light switch. The discovery could lead to ultrafast, energy-efficient superconducting transistors for neuromorphic devices — electronics designed…

Contact lenses to treat dry eye syndrome

A collaborative team from the Terasaki Institute for Biomedical Innovation (TIBI) has developed a contact lens prototype that is specifically designed to prevent contact lens-induced dry eye (CLIDE). The lens alleviates this condition by facilitating tear flow in response to normal eye blinking. This approach can relieve the discomfort, visual…

Why are muskies the fish of 10,000 casts? Study explains

For anglers, landing a muskellunge, or muskie, is a big deal. The “fish of 10,000 casts” is notoriously elusive, making the massive fish an even bigger prize when one finally strikes a lure. In a new study, University of Illinois researchers got into the minds of muskies to learn what…

Researchers demonstrate non-invasive method for assessing burn injuries: Neural network based on terahertz spectroscopy data predicts burn healing with 93% accuracy

Researchers have developed a neural network model that uses terahertz time-domain spectroscopy (THz-TDS) data for non-invasive burn assessment. They combined the new approach with a handheld imaging device that they developed specifically for fast THz-TDS imaging of burn injuries. “It is important for healthcare professionals to accurately assess the depth…

Mating causes ‘jet lag’ in female fruit flies, changing behavior

An innovative technique from Cornell University researchers finds seminal fluid protein transferred from male to female fruit flies during mating changes the expression of genes related to the fly’s circadian clock. The finding, published in the Proceedings of the National Academy of Sciences, could help explain how this protein, called…

Novel cancer therapy extends lives of terminally ill dogs

Dogs are humans’ best friendsand it is always distressing for dog owners when their beloved pets contract terminal illnesses. Canine cancer is the leading cause of death in dogs and when they are diagnosed with late-stage or terminal illness, there are often no treatment options available. In a recent study,…

Researchers work to reduce the amount of precious metals in catalytic converters: Not only could the research make catalytic converters less attractive to thieves, but it could also help the environment.

The precious metals, such as platinum, palladium and rhodium, in catalytic converters make the vehicle devices attractive to thieves, but University of Central Florida researchers are working to reduce the amount of precious metals needed in them — down to single atoms — while still maximizing their effectiveness. Catalytic converters,…

Study reframes understanding of graft-versus-host disease

New research challenges the prevailing hypothesis for how donor stem cell grafts cause graft-versus-host disease, or GVHD, and offers an alternative model that could guide development of novel therapies. Published today in Immunity, the study showed in a mouse model that GVHD, which often affects the skin, gut and liver,…
