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…

During their quarterly conference call, Legend Biotech executives expressed little concern about new threats to the company’s only commercial product, the multiple myeloma CAR-T Carvykti. Oddly enough, this competition is being conducted through Karvicti’s commercial partner, Johnson & Johnson. Over the past three months, the pharmaceutical giant has announced data from two successful trials of its multiple myeloma bispecific Tecvayli. One in combination with J&J’s Darzalex and the other with BCMAxCD3 T-cell engager as a single agent. The results of the study show a competitive profile compared to Carvykti, and the combo quickly won FDA approval last week. During Tuesday’s…

Young people with depression exhibit abnormal cellular energy patterns in both the brain and blood, characterized by overactive cells at rest, but unable to respond appropriately to physical stress. This biological manifestation of fatigue suggests that early medical intervention may help restore cellular balance before long-term physical damage occurs. The study was published in the journal translational psychiatry. Fatigue is a common and disabling symptom of major depressive disorder. Despite the prevalence of this severe fatigue, its biological origins remain largely a mystery. Medical professionals need a clearer picture of how depression changes the body at a microscopic level to…

Researchers have developed a capsule-based method that allows them to analyze the same cells through multiple experimental steps. This technology could overcome long-standing limitations in cell research and open new ways to study disease mechanisms at the single-cell level. In a study published in a scientific journal scienceVisiting Professor Linas Mazutis and his research team at Umeå University have presented a new technique for analyzing individual cells. This method addresses long-standing technical challenges in cell research. Until now, scientists have typically been able to analyze each cell only once, making it difficult to study how individual cells change or respond…
