Researchers have discovered that distinct clusters of brain cells in mice act like on and off switches for gender-specific social behavior. This cluster is permanently turned on in females, but remains silent in adult males until mating. This strictly dualistic brain feature provides new insights into how social and reproductive life stages physically change the brain. The results of this research have recently Proceedings of the National Academy of Sciences. There are obvious physical differences between male and female bodies in anatomy and hormones. Biologists refer to these sex-based physical differences as sexual dimorphism. In the brain, these physical distinctions…

Wouldn’t it be great if you could just buy a couple of solar panels at Walmart in the morning, connect them to your deck in the afternoon, and within a few hours have them set up to generate clean energy that lowers your electric bill? But that’s not an option for most Americans right now. First, this device is not widely available in US stores. If so, you may have to jump through a series of hoops with your utilities to get them up and running. Virginia lawmakers are trying to change everything for the state’s residents. On Wednesday, Virginia’s…

New Mexico environmental officials announced Thursday an agreement with four Curry County dairy farms to test groundwater contaminated by a plume of so-called “forever chemicals” emanating from Cannon Air Force Base. The state says the agreement represents “an important step toward full restoration.” Zachary Ogas, general counsel for the Department of the Environment, told Source NM that the agreement came about because environmental officials “spent a lot of time in Clovis with the people who were actually affected.” New Mexico Environmental Officials Announce Blood Tests in Clovis Area Show “Forever Chemical” The contamination was first discovered in 2015, and the…

High novelty-seeking personality traits may increase the risk of relapse after alcohol withdrawal. This discovery is Psychiatric Research Journal. Alcohol use disorder remains a major public health challenge in France, with millions of people suffering from harmful drinking patterns. Personality traits can shape a person’s vulnerability to addiction, but few studies have investigated how these traits influence recovery in the months following withdrawal. Past research suggests that impulsivity, difficulty regulating emotions, and sensitivity to reward may all contribute to addiction. The team, led by Anne-Laure Virevialle from the Center Hospitalier Esquirol, aimed to better understand why some people relapse so…

The kickoff signals for puberty begin in the brain. Specifically, in the hypothalamus, certain neurons release hormones that activate the pituitary gland at the base of the skull, which then releases other hormones to initiate maturation of the gonads (ovaries or testes). This mechanism leading to fertile organisms is the hypothalamic-pituitary-gonadal (HPG) axis. Research by Spain’s National Cancer Research Center (CNIO) has discovered in animal models that two previously unsuspected elements are also involved in this hormonal regulatory system. microglia (defense cells of the nervous system) and RANK, a protein that contributes to bone remodeling and is essential for mammary…

Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder, affecting 12% to 13% of adolescents in the United States, according to several studies. Patterns of inattention, hyperactivity, and impulsivity can interfere with daily life and cause problems at home, work, and school. At the same time, people diagnosed with ADHD are at increased risk of developing a substance use disorder. However, treating the combination of these two conditions can be complicated. A team led by researchers at Penn State College of Medicine identified treatment disparities among adolescents and young adults diagnosed with both ADHD and substance use disorders. In a study…

There are more than 100 million neurons in the gastrointestinal tract, and in many cultures, including ancient Greece, Japan, China, and India, the gut is commonly known as the “second brain,” linking digestion to physical and mental health.Now, new research from Emory University explains the connection between the gut and the brain, showing that live bacteria from the gut can directly invade the brain, with potential effects on neurological health. Published in PLOS Biology The study, published in March, was conducted in a mouse model and demonstrated that live bacteria from an imbalanced gut flora can enter the brain via…

Physicians’ use of artificial intelligence has more than doubled since 2023, with an American Medical Association survey reporting that 81% currently use the technology in professional settings. Additionally, approximately 1,700 physician respondents surveyed in January and February reported an average of 2.3 use cases. This is also up from an average of 1.1 use cases in 2023, when organizations first began their near-annual poll on the topic. Most common among physician users were applications focused on documenting clinical care and summarizing medical research. The AMA noted that the percentage of physicians using AI in research summaries and standard of care…

Scientists from the University of Almería and the University of Granada, in collaboration with researchers from the Leiden University Medical Center (LUMC, the Netherlands), have identified gut bacteria of the genus Roseburia that are associated with stronger muscles and improved physical condition. This result supports the concept of a gut-muscle axis. “Taken together, our findings provide solid evidence supporting the existence of a gut-muscle axis in which this identified bacterium actively regulates muscle metabolism and muscle strength,” says Jonathan Lewis, professor in the UGR Faculty of Physical Education and Sport and researcher at the Interuniversity Research Institute for Sport and…

New research in the March 2026 issue JNCCN – National Comprehensive Cancer Network Journal It has been suggested that exercise, through chemotherapy given in fortnightly cycles, may help cancer patients become mentally sharp and better able to cope with daily life, work and social activities. In this first-of-its-kind, national, multicenter, Phase III trial, patients were randomly assigned to receive an exercise prescription, Exercise for Patients with Cancer (EXCAP©®). In addition to regular chemotherapy, this regimen includes personalized walking and simple resistance band exercises. By the end of the study, patients who underwent two-week chemotherapy cycles and followed the EXCAP exercise…
