Self-powered patch monitors biomarkers without drawing blood

Just as smart traffic management ensures smooth vehicular movement during peak hours, our body relies on a molecular traffic system to manage the surge in glucose levels after a meal. Pancreatic β-cells play a major role in this system by taking up glucose from the blood and triggering insulin release into the bloodstream. Inside these cells, glucose uptake is managed by glucose transporters (GLUTs)—proteins that move to the β-cell surface when blood glucose levels rise and facilitate the entry of glucose into the cell to kickstart insulin release.

A new comprehensive atlas of cells fills gaps in knowledge on how different cells in the intestine act together to drive celiac disease, potentially opening new avenues for future therapeutic intervention.

Hundreds of people may have been exposed to rabies after staying in cabins infested with bats at Wyoming's Grand Teton National Park.

There is a weak correlation between change in cognitive impairment and change in work productivity loss in adults with bipolar disorder, according to a study published online Aug. 4 in the Neuropsychopharmacology Reports.

The Texas measles outbreak that sickened 762 people since late January is over, state health officials said Monday.

Lymph nodes are a key part of the human immune system, whose primary function is to combat infections. The effectiveness of vaccines is based on their ability to trigger events in lymph nodes that lead to the development of an immune response that protects the host against pathogens.

A new wireless and wearable device developed by Northwestern Medicine scientists, in collaboration with Northwestern University spinout company, Epicore Biosystems, measures specific biomarkers in a person's sweat with similar accuracy to standard testing methods and has the potential to improve clinical decision-making for cystic fibrosis, as detailed in a recent study published in the Proceedings of the National Academy of Sciences.

Innovative intervention delivered by trained community health workers—meaning nonclinical personnel with deep knowledge of the community—increased treatment utilization among participating families with children who have ADHD, according to a pilot study published in the Journal of Attention Disorders. This intervention for parents and caregivers, covering topics that range from education about ADHD to discussions of stigma and barriers to care, intends to reduce inequities in access to evidence-based treatment and boost family engagement in ADHD care.

The Society for Cardiovascular Angiography & Interventions (SCAI) has published a new position statement that provides best-practice guidance for the treatment of patent ductus arteriosus (PDA) using transcatheter occlusion (tcPDA) in premature infants.

Zhengang Lu and Russell Epstein, from the University of Pennsylvania, led a study to explore how people maintain their sense of direction while navigating naturalistic, virtual reality cities.

Researchers have created the first detailed molecular map of the human bone marrow, revealing new insights that could reshape our thinking about how an incurable blood cancer grows and spreads.

A multicenter French study led by Rennes University Hospital reports potential benefits of glucagon-like peptide-1 receptor agonists for hidradenitis suppurativa (HS), with statistically significant reductions in HS-related scores at six months and at last follow-up.

When it comes to adopting artificial intelligence in high-stakes settings like hospitals and airplanes, good AI performance and brief worker training on the technology is not sufficient to ensure systems will run smoothly and patients and passengers will be safe, a new study suggests.

Sports coaches have always made decisions based on experience, observation and intuition. But they are increasingly relying on hard evidence. Behind the scenes, a quiet revolution is transforming sport—driven not by human skills but by data.

Imagine you purchase a bag of gummies labeled nootropic—a term used to describe substances that claim to enhance mental ability and function, or "smart drugs." However, within hours of consuming them, your heart starts racing, you're nauseated and vomiting. Then you begin convulsing and have a seizure, resulting in a trip to the hospital.

Gazing at smartphone screens for even one hour a day can cause digital eye strain, especially when scrolling through social media. According to a new study published in the Journal of Eye Movement Research, it is not just the time spent on digital devices but also the type of content being used that can cause the condition.

For almost 40 years, people who suspect they've been harmed by a vaccine have been able to turn to a little-known system called the Vaccine Injury Compensation Program—often simply called the vaccine court.

A new study reports evidence of a link between prenatal exposure to the widely used insecticide chlorpyrifos (CPF) and structural abnormalities in the brain and poorer motor function in New York City children and adolescents.
