In southern Africa, a group of people lived in partial isolation for hundreds of thousands of years. This is shown in a new study based on analyses of the genomes of 28 people who lived between 10,200 and 150 years ago in southern Africa. The researchers also found genetic adaptations that likely shaped Homo sapiens as a species. The study, which is the largest to date of African ancient DNA, is published in Nature. Homo sapiens has been around for at least 300,000 years. But exactly where on the African continent our species ...

Neutrophils are the most abundant immune cells in the body and the first to respond to infection or tissue damage. Yet despite their importance, until now very little was known about how they truly function, how they change depending on the tissue they inhabit, or how they contribute not only to host defense but also to inflammatory, cardiovascular, or cancer-related diseases. Their diverse actions enable them to save lives during infection but can also worsen inflammation, as seen in conditions such as COVID-19. To unravel this complexity, an international consortium led by scientists at the Centro Nacional de Investigaciones Cardiovasculares (CNIC), Universidad Carlos ...

Neutrinos, though nearly invisible, are among the most numerous matter particles in the Universe. The Standard Model recognizes three types, but the discovery of neutrino oscillations revealed they have mass and can change identity while propagating. For decades, puzzling experimental anomalies have suggested the presence of a fourth, sterile neutrino, one that interacts even more weakly. Finding it would transform our understanding of particle physics. In a new study, published in Nature, the KATRIN collaboration presents the most precise direct search for sterile neutrinos through measurements of tritium β-decay. The ...

About The Study: This cross-sectional study found that older U.S. adults are increasingly treated with antipsychotics, with a growing share receiving them from long-term care pharmacies and a declining percentage from psychiatrists and for first-generation medications. An increase in prescribing by non-psychiatrists contributed to the overall trend.  Corresponding Author: To contact the corresponding author, Mark Olfson, MD, MPH, email mo49@cumc.columbia.edu.

Key Takeaways In an analysis of more than 5,000 Maryland homicide victims who died from gunshot or stabbing wounds, more than 70 individuals could have survived if bleeding control techniques had been applied before arriving at the hospital — a small but significant and likely under-reported number, trauma experts said. Research underscores the life-saving potential of Stop the Bleed for both urban and rural communities, where access to trauma care may be delayed. CHICAGO — Quicker access to bleeding control interventions taught in the American College of ...

Complex life began to develop earlier, and over a longer span of time, than previously believed, a groundbreaking new study has revealed. The research sheds new light on the conditions needed for early organisms to evolve and challenges several long-standing scientific theories in this area.  Led by the University of Bristol and published in the journal Nature today [3 December], the research indicates that complex organisms evolved long before there were substantial levels of oxygen in the atmosphere, ...

About The Study: The results of this randomized clinical trial show that adjunctive semaglutide significantly improved glycemic control and weight outcomes in individuals with schizophrenia spectrum disorders. Secondary outcomes were exploratory. These findings support the use of glucagon-like peptide–1 receptor agonists (GLP-1RAs) as a potential early intervention strategy to reduce cardiometabolic risk in this vulnerable population.  Corresponding Author: To contact the corresponding author, Anders Fink-Jensen, DMSci, email anders.fink-jensen@regionh.dk.

PHILADELPHIA – For decades, health-related statements by major professional health associations such as the American Medical Association (AMA) agreed with those of the Centers for Disease Control and Prevention (CDC) because both relied on the same body of scientific knowledge, much of it funded by the federal health sector. However, the public can no longer assume that the CDC and major public health organizations are on the same page.  In late November 2025, for example, when the CDC website legitimized the ...

Surprisingly, some of the universe’s brightest objects are black holes. As scorching gas and dust flow around and into a black hole, they glow with fierce intensity across the light spectrum. Now, a team of computational astrophysicists has developed the most comprehensive simulations ever made of how black holes create these dazzling light shows. Using supercomputers, the researchers calculated the behavior of material zipping around black holes. Unlike all previous studies that relied on simplifying approximations, the researchers utilized a full treatment of how light moves and interacts with matter ...

A new study by a research team at Université de Montréal highlights a critical lack of knowledge about the cognitive profiles of people living with both schizophrenia and a personality disorder.   A comprehensive review of scientific literature from the past 24 years, published in Schizophrenia Research: Cognition, reveals that despite the high prevalence of this dual diagnosis (affecting approximately 40 per cent of people diagnosed with schizophrenia) and its association with unfavourable outcomes, the available data are surprisingly limited and fragmented.  “Our analysis shows a significant blind spot in current ...

SAN ANTONIO — December 3, 2025 — Southwest Research Institute (SwRI) scientists believe they may have resolved a 39-year-old mystery about the radiation belts around Uranus. In 1986, when Voyager 2 made the first and only flyby of Uranus, it measured a surprisingly strong electron radiation belt at significantly higher levels than anticipated. Based on extrapolations from other planetary systems, Uranus’ electron radiation belt was off the charts. Since then, scientists have wondered ...

The dark web – a hidden corner of the internet accessed through privacy-preserving tools like the Tor browser – operates beyond the reach of traditional search engines and public platforms. Unlike the surface web, its architecture is deliberately designed to shield identities and activities from view, prioritizing anonymity over transparency. Although the dark web has existed for more than 20 years, research assessing mental health differences between its users and those who stay on the surface web remains limited. Its pseudo-anonymous ...

Managers’ narcissistic tendencies may fundamentally affect whether a company makes risky or safe moves as a response to the firm’s above-aspiration performance, according to a new study published in Strategic Management Journal. In a study that helps to clarify prior conflicting research, the researchers find evidence that high-narcissism CEOs respond to above-aspiration performance with more acquisitions, while low-narcissism CEOs avoid acquisitions. The study authors — Korcan Kavusan of Erasmus University, Daniel Z. Mack of Singapore Management University, Matthew P. Mount of ...

PULLMAN, Wash. — In times of economic upheaval, investors can get a clearer picture of the stock market’s future performance if they tune into how corporate insiders are trading stocks in their own companies. That’s a key finding from a new study of investor behavior during the Covid-19 pandemic from Washington State University researchers. The study, which was published in Pacific-Basin Finance Journal, examined the trading choices of insiders during the unprecedented market shocks of the Covid-19 pandemic — finding they often zigged when the market zagged. When most investors were selling stocks ...

To see if a fish is fresh, people recommend looking at its eyes and gills or giving it a sniff. But a more accurate check for food quality and safety is to look for compounds that form when decomposition starts. Now, researchers reporting in ACS Sensors have developed a simple, effective electronic device that quickly measures one of these compounds. The prototype sensor can determine how fresh a fish is in less than two minutes. For fish, signs of spoilage (cloudy eyes, bruised gills, foul or fishy odors) might take hours or even days to appear. In contrast, compounds such as hypoxanthine (HX) start forming ...

The microbes inside our bodies not only help break down food but also impact our health. Yet their precise influence is not always understood, especially in the presence of prescription drugs. Now, researchers in ACS Central Science report how one of the most abundant gut bacteria responds to tetracyclines, a class of commonly prescribed antibiotics. Newly characterized signals released by the bacterium could aid the host’s immune response, inhibit pathogens and restructure the gut microbiome. “We previously showed that exogenous molecules ...

FERNANDINA BEACH, Fla., December 3, 2025 – The Family Heart Foundation, a leading research and advocacy organization, published new research in the American Journal of Preventive Cardiology revealing significant gaps in cholesterol management during 2022-23 among U.S. adults with atherosclerotic cardiovascular disease (ASCVD). Findings show that only 13% of adults with ASCVD were meeting three key components of optimal low-density lipoprotein-cholesterol (LDL-C) management, including receiving guideline-recommended therapy, consistently taking ...
