Medicare drug plans are increasingly excluding coverage of new specialty drugs that treat complex conditions like cancers and autoimmune diseases. New research from the USC Schaeffer Center shows how these barriers may come at a cost to patients’ health. In a large study of Medicare beneficiaries with multiple sclerosis (MS), researchers found those in plans with broader coverage of MS treatments had significantly lower risk of developing new or worsening symptoms months later. The findings, published Aug. 1 in JAMA Network Open, suggest that plans with narrower coverage of MS treatments may be linked to worse health ...

A new paper published today in Cell highlights how researchers have leveraged AI-based computational protein design to create a novel synthetic ligand that activates the Notch signaling pathway, a key driver in T-cell development and function. These so-called soluble Notch agonists can be broadly applied to optimize clinical T-cell production and advance immunotherapy development. Notch signaling is central to many cellular differentiation processes and is essential in transforming human immune cells into T-cells that target ...

About The Study: This cross-sectional study found that when adolescents had their phones at school, they spent nearly an hour per school day on smartphones, with most of this time on social media. The results extend prior work indicating that smartphone use during instructional hours, especially social-specific use, is not trivial. These results also highlight developmental differences, with younger adolescents using smartphones and social media less than older adolescents.

The earliest warning signs of multiple sclerosis (MS) may emerge more than a decade before the first classical neurological symptoms occur, according to new research from the University of British Columbia. Published today in JAMA Network Open, the study analyzed the health records of more than 12,000 people in British Columbia and found that those with MS began using healthcare services at elevated rates 15 years before their first MS symptoms appear. The findings challenge long-held assumptions about when the disease truly begins, offering the most comprehensive ...

A new artificial intelligence (AI) tool could make it much easier—and cheaper—for doctors and researchers to train medical imaging software, even when only a small number of patient scans are available. The AI tool improves upon a process called medical image segmentation, where every pixel in an image is labeled based on what it represents—cancerous or normal tissue, for example. This process is often performed by a highly trained expert, and deep learning has shown promise in automating this labor-intensive task. The big challenge is that deep learning-based ...

A new study led by researchers at the Ineos Oxford Institute for antimicrobial research (IOI) has found that antimicrobial resistant bacteria is spreading rapidly among children being treated for severe malnutrition in a hospital facility in Niger. The findings have been published today (1 August) in Nature Communications Globally 45 million children under the age of five are estimated to be severely malnourished. These children are also at a higher risk of developing life-threatening infections such as tuberculosis or sepsis due to their weakened immune systems. Working with Médecins Sans Frontières (Doctors Without Borders), researchers analysed over 3,000 ...

Most U.S. households could reduce their electricity costs and endure power outages by installing rooftop solar panels and battery packs, according to a new Stanford University study, though people may need to buy the equipment by Dec. 31. About 60% of families could reduce their electricity costs by 15% on average by installing a solar-battery system. That’s after accounting for annualized capital and operating costs of the equipment. Some 63% of U.S households could also weather local or regional blackouts with such systems, able to meet about half their electricity needs on average. These households would either save money on electricity or ...

From exoskeletons that help spinal injury patients walk to algorithms that can predict the onset of dementia years in advance, Caligiore explores what he describes as a ‘revolution’ ...

Intestinal bacteria are important for human health as they help digest food and regulate immune function. Thus, in recent years, it has become clear that gut microbiota dysbiosis, an imbalance in types and composition of intestinal bacteria, is associated with digestive disorders and other diseases. However, the mechanism by which bacteria interact in the intestine to maintain the microbiota balance remains unclear. A research group led by Associate Professor Koji Hosomi at Osaka Metropolitan University’s Graduate School of Veterinary Science studied two bacteria: Fusobacterium varium (F. varium), an oral and intestinal bacterium linked to inflammation and colon ...

Hearing loss is the most common form of sensory disability. Approximately 1.6 billion people around the world currently live with from some degree of hearing loss, and the WHO has forecast that this number will rise to 2.5 billion by 2050. People with hearing loss tend to experience more stress and anxiety at school or work, and as a result take more days off sick. The annual global cost of unaddressed hearing loss may run to $1 trillion. Now, a long-term observational study has found that young adults with hearing difficulties in the US have less educational ...

Dr. Jung-Dae Kwon's research team at the Energy & Environmental Materials Research Division of the Korea Institute of Materials Science (KIMS, President Chul-Jin Choi) has successfully developed an amorphous silicon optoelectronic device with minimal defects, even using a low-temperature process at 90°C. Notably, the team overcame the limitations of high-temperature processing by precisely controlling the hydrogen dilution ratio—the ratio of hydrogen to silane (SiH₄) gas—enabling the fabrication of high-performance ...

Trigger warnings may not help students feel more supported, but safe space messages do. A new study found that being told they were in a ‘safe space’ made students feel more comfortable, trusting, and positive toward the person delivering them. Researchers from Flinders University and collaborators in the United States studied the responses of 738 U.S based university students. Each student watched a short trauma-related lecture introduced by an instructor with either a trigger warning, a safe space message, both, or neither. Students ...

A synthetic opioid 1000 times more potent than morphine is infiltrating the street drug trade in Adelaide, Australia, sparking fears of a wave of overdoses that could be lethal.

The results reveal that better outcomes for patients can be achieved in a group setting using the cycling and ...

LA JOLLA (July 31, 2025)—Proteins sustain life as we know it, serving many important structural and functional roles throughout the body. But these large molecules have cast a long shadow over a smaller subclass of proteins called microproteins. Microproteins have been lost in the 99% of DNA disregarded as “noncoding”—hiding in vast, dark stretches of unexplored genetic code. But despite being small and elusive, their impact may be just as big as larger proteins. Salk Institute scientists are now exploring the mysterious dark side of the genome in search of microproteins. With their new tool ShortStop, researchers ...
