Astronomers have glimpsed the inner workings of a dying star in a rare type of cosmic explosion called an “extremely stripped supernova.” In a paper published in natureSteve Schultz of Northwestern University and colleagues describe supernova 2021yfj and the thick shell of gas that surrounds it. Their findings support existing theories about what happens inside massive stars at the end of their lives and how they have shaped the building blocks of the universe we see today.How stars make elementsStars are powered by nuclear fusion. Fusion is a process in which lighter atoms are crushed into heavier atoms, releasing energy.…
An international analysis combining brain imaging data from multiple independent studies has identified common patterns in how psychedelic drugs alter communication between different brain networks. Researchers have found that substances such as psilocybin and LSD reliably increase functional connectivity between brain regions responsible for sensory input and brain regions involved in abstract, associative thinking. The research results were published in a magazine natural medicine. In recent years, classic psychedelic drugs such as psilocybin, LSD, and DMT have re-entered the mainstream of psychiatric research as experimental treatments for conditions such as depression and anxiety. All of these substances reliably bind to…
When negotiating with a woman, people tend to be more satisfied and enthusiastic about the upcoming interaction. Recent research is Proceedings of the National Academy of Sciences This suggests that women achieve the same economic outcomes as men while simultaneously fostering better interpersonal relationships. The strength of these relationships provides evidence that women are better at the social aspects of transactions, which may lead to compounding economic advantages over time. Negotiation is essentially a discussion aimed at reaching an agreement where parties may have conflicting or common interests. These conversations happen everywhere, from discussions about formal job pay to everyday…
New research published in oncology science Glioblastoma is exploring a potential new approach to the treatment of brain tumors, a malignancy that remains extremely difficult to treat. The paper is titled “Selective blood-brain barrier penetration and tumor targeting of nitrosylcobalamin in glioblastoma: pharmacokinetics, tissue distribution, and synergistic activity with TRAIL and temozolomide.” The study was led by first and corresponding author Joseph A. Bauer of Nitric Oxide Services, LLC and Cleveland Clinic Foundation Taussig Cancer Center. The research team investigated nitrosylcobalamin (NO-Cbl), a modified form of vitamin B12 that releases nitric oxide, to see if it could cross the blood-brain…
Practicing a specific type of slow, guided breathing every day for eight weeks reduces the body’s fight-or-flight response to psychological stress in veterans dealing with post-traumatic stress disorder. The findings suggest that consistent breathing exercises may help protect long-term cardiovascular health in people with trauma-related mental illness. The study was published in the American Journal of Physiology-Regulatory, Integrative and Comparative Physiology. Post-traumatic stress disorder is a severe mental health condition that develops after experiencing a frightening event. People with this disease have a much higher risk of developing high blood pressure and heart disease later in life. This increased risk…
Big life events can shape personality, but their impact varies greatly depending on who experiences them and how they interpret them. That’s the conclusion of a new study published in the journal Nature. personality journal. The study found that factors such as age, gender, a person’s perceptions, and even who is assessing their personality influence whether an event is associated with lasting change. Although personality traits are often viewed as relatively stable traits, research has shown that people can change over time. Events such as entering into a romantic relationship, becoming a parent, experiencing illness, and changing jobs have all…
As many people age, they notice the familiar change in their waistline that gradually expands, even if their overall weight doesn’t change dramatically. This increase in abdominal fat is more than just a cosmetic issue. Excess belly fat is associated with slower metabolism, accelerated aging, type 2 diabetes, heart disease, and other chronic health problems. Scientists have long known that body composition changes with age, but exactly why fat is more likely to accumulate around the midsection remained unclear. Now, City of Hope researchers have identified what may be the main biological cause of age-related belly fat. Their findings were…
A new commentary published in the Journal of the Royal Society of Medicine warns that the current risk-based regulatory approach to artificial intelligence (AI) in healthcare is insufficient to protect patients and could lead to over- or under-treatment and even discrimination against patient groups. The authors found that although AI and machine learning systems can improve clinical accuracy, concerns about their inherent inaccuracy, opacity, and potential for bias remain, and are not adequately addressed by current regulatory efforts introduced by the European Union’s AI legislation. The AI Act, passed in 2025, classifies medical AI as “high risk” and introduces strict…
The development of a pioneering gene therapy to treat a devastating rare immune disease led by UCL scientists is about to move to the next stage following promising early preclinical studies. CTLA-4 deficiency is a rare disease of white blood cells known as regulatory T cells, which normally help regulate the immune system, and effector T cells, which protect the body from repeated infections and cancer. This is caused by the lack of the CTLA-4 protein, which is produced by a specific gene. Most people have two functioning copies of the gene, but people with the disease have only one…
Background and purpose In the United States, digital pathology (DP) is moving from an adjunct technology to an enterprise diagnostic platform. Despite accelerating clinical adoption, many laboratories face persistent barriers such as high capital and operating costs, workflow disruptions, interoperability challenges, and complex regulatory and reimbursement environments. This narrative review focuses on defining and operationalizing an organization’s artificial intelligence (AI) readiness for safe and sustainable adoption and proposes a practical lifecycle framework for implementing and sustaining a DP program. method We performed a targeted narrative review based on PubMed/MEDLINE and Google Scholar searches for English-language publications from January 1, 2014…
