For the millions of people who carry the gene APOE4, the strongest known genetic risk factor for Alzheimer’s disease, brain activity can begin to change long before memory problems appear. Now, researchers at the Gladstone Institute have uncovered the exact chain of molecular events behind the initial changes and identified potential ways to reverse them. Published in a magazine natural aging, Their new research using a mouse model reveals how APOE4 triggers increased production of the protein Nell2, causing neurons to shrink and become hyperactive. The more hyperactive the neurons are during early childhood, the more severe the memory deficits…

A research team from Tohoku University and Future University Hakodate has demonstrated that living biological neurons can be trained to perform supervised temporal pattern learning tasks that were previously performed by artificial systems. By integrating cultured neuronal networks into a machine learning framework, the research team showed that these biological systems can generate complex time-series signals, a major advance in both neuroscience and bio-inspired computing. The study, published online in the Proceedings of the National Academy of Sciences (PNAS) on March 12, 2026, highlights a new interface between living neural systems and computational techniques. This finding suggests that biological neural…

Blue Shield of California’s Virtual Blue Plan continues to deliver positive results for enrolled members, including a 7% to 10% reduction in overall treatment costs, the insurer announced Thursday. The Virtual First program first launched in 2023 in collaboration with Accolade and TeleMed2U and has more than 150,000 members to date. This allows members to access numerous virtual health services at no additional charge, as well as receive care from providers within Blue Shield’s PPO network. Tim Reeve, Blue Shield of California’s senior vice president of commercial markets, said in a statement that the platform is “a win for our…

A new study investigates factors that promote job satisfaction and retention intentions among nurses working in public clinical centers in Kazakhstan. Based on a cross-sectional survey of 359 nurses, researchers found that although nurses were generally satisfied with their jobs, their motivation to stay was only moderate. The findings of this study highlight mentoring, assessment, professional role development, and a supportive practice environment as important tools for strengthening the nursing workforce during a period of healthcare reform in Kazakhstan. Main findings This study surveyed 359 nurses at two public clinical centers in Kazakhstan using the Casey Fink Nurse Retention…

New research from Trinity College Dublin’s Global Brain Health Institute (GBHI) reveals that brain health has important implications for prevention, public health and policy. An international study published in 34 countries shows that the biological age of the brain can be accelerated or delayed by environmental risks (air pollution, social housing conditions) and protective factors (socioeconomic equality, access to health care). More powerful influences arise from the interaction between environmental, social, and political conditions. The paper is published today (Friday, April 3, 2026) in the journal Nature Medicine. How do the complex environments in which people live together shape the…

A study of incarcerated men found that men with pronounced psychopathic traits were more likely to unconsciously divert their attention from sad faces when made to feel experimentally sad. In the same situation, attention to angry faces increased. The paper was published in. Journal of Experimental Psychopathology. Psychopathy is a pattern of stable personality traits that includes low empathy, shallow emotions, and a tendency toward manipulative or antisocial behavior. Core characteristics of psychopathy include callousness, lack of guilt or remorse, superficial charm, and impulsivity. Although psychopathy is associated with an increased risk of antisocial and criminal behavior, it does not…

WASHINGTON — The White House is asking Congress to cut spending at the Department of Health and Human Services by more than 12%, according to the 2027 federal budget proposal released Friday. The budget is largely similar to what the Trump administration proposed last year. This includes deep cuts to the National Institutes of Health, the elimination of the Health Research Agency, and the creation of a new agency dedicated to chronic diseases called the Healthy America Administration. The president’s budget proposal is an agenda-setting document, indicating what the administration wants to focus on next year. However, the ultimate responsibility…

A giant barn owl, a type of rodent called a hutia, and a burrowing bee entered the cave. Only two people remained. Which one is left? The answer is impossible. This unusual series of events likely occurred on the Caribbean island of Hispaniola thousands of years ago. The owl brought Huthia back to the cave to feed the chicks. The meal was quickly over, and the bodies of the unfortunate rodents littered the cave floor. Much later, bees came looking for a place to nest in the rubble left behind. How did bees turn into fossils and become nests? The…

“What should I eat?” is one of the most common questions people with inflammatory bowel disease ask their doctors. It’s also the most difficult question to answer. Inflammatory bowel diseases, such as ulcerative colitis and Crohn’s disease, are less well studied when it comes to diet. Large, well-controlled studies of dietary modification are limited. Now, researchers at Stanford Medicine and Collaborative Research may be looking to fill that gap. A national randomized controlled trial found that a short-term calorie-restricted diet plan produced meaningful improvements in both symptoms and biological markers in patients with mild to moderate Crohn’s disease. The results…

Recent research published in biological psychiatry present evidence that experiencing abuse or neglect in childhood is associated with specific physical changes in brain structure that vary by age and gender. This study suggests that these structural differences are most pronounced during young adulthood, with young women exhibiting the most extensive brain changes after early life adversity. A broad international team of researchers representing dozens of institutions in eight countries initiated this study to better understand the relationship between childhood adversity and brain development. Many people who experience abuse in childhood eventually develop stress-related mental health conditions such as major depressive…
