Carnegie Mellon University and University of California, San Francisco researchers have found that childhood trauma, poverty, social isolation and other adverse life experiences are associated with brain changes linked to schizophrenia-spectrum disorders—findings that could help researchers identify people at risk earlier and develop interventions before severe symptoms emerge.
In one of the largest studies of chemical exposures during pregnancy to date, new research led by the UNC Gillings School of Global Public Health, Stanford University School of Medicine and Woods Institute for the Environment has found that pregnant women are exposed to dozens of everyday chemicals, many of which can affect how early a child is born or a child's weight at birth. These outcomes influence a child's health throughout life.
Anorexia nervosa is a psychiatric disorder characterized by persistent restriction of food intake, fear of gaining weight and distorted body image, often leading to significantly low body weight. Relapse rates for people treated for the disorder are alarmingly high, at up to 50% within one year of the person restoring body weight. The disorder has one of the highest mortality rates of any psychiatric disorder, with suicide being the leading cause of death.
Plague is commonly associated with rats, crowded medieval cities, and the epidemics that swept across Europe during and after the Middle Ages. But a new study published in Nature shows that the disease was already lethal 5,500 years ago, when it killed humans in small, mobile hunter-gatherer communities—long before the rise of agriculture and cities created the conditions usually associated with plague epidemics.
Birdwatching is one of the most common and popular ways people experience nature. But it's not often that even the most enthusiastic birdwatcher returns to the same place more than 800 times to witness the changes over four decades.
A prototype quantum sensor developed by researchers at Imperial has demonstrated for the first time that a key principle behind next-generation quantum detectors can work under realistic conditions.
A new study from Michigan State University found increases in binge eating when taking hormone pills in the form of oral contraceptives—but not in all women. This is the first large-scale study of changes in binge-related symptoms with oral contraceptive use.
A new study published in Nature shows that rock weathering increasingly counteracts river CO2 emissions as permafrost degrades. The study was carried out by a collaborative team of researchers from Umeå University in Sweden and East China Normal University.
Newborn nerve cells must squeeze through crowded, narrow spaces—through dense tissue, past other cells, and between fibers—to reach the areas where they form neural circuits in the brain cortex. In a study published in Nature, researchers at Kyoto University's Institute for Integrated Cell-Material Sciences (WPI-iCeMS) and their collaborators report that this journey causes widespread DNA damage in neurons, resulting in double-strand breaks in which both strands of the double helix are completely severed.
New Oxford University-led research reveals that bees can regulate their feeding to avoid overconsuming certain essential nutrients, and that honey bees make a specialist "baby food" that gives their larvae a better-balanced diet.
This NASA Hubble Space Telescope image features the galaxy cluster MACS0329-0211.
Looking somewhat like a swarm of bees returning to their hive, this NASA Hubble Space Telescope image released on June 12, 2026, features the galaxy cluster MACS0329-0211. Galaxy clusters like MACS0329-0211 are important signposts in the story of how the structure of the universe evolved, and are the ultimate telescopic lenses, placing gravitationally lensed galaxies from the […]
A simple shot given shortly after birth can protect babies from a rare but potentially life-threatening condition known as vitamin K deficiency bleeding (VKDB). When newborns don't have enough vitamin K, their blood can't clot effectively, putting them at risk of severe internal bleeding in the intestines or the brain, which can cause organ damage or even prove fatal.
Big cats have a big impact. A long-term study showed that when mountain lions began regular visits to a small suburban preserve about 45 miles (72 kilometers) south of San Francisco, they changed the behavior of many other animals.
A reality TV star's claim that a beta blocker dulled their emotions and made them appear calm on camera has sparked a wave of social media commentary.
Whales and dolphins inhabit some of the largest and seemingly most pristine environments on Earth, from tropical coastlines to Antarctic waters. Yet even they cannot escape PFAS—persistent "forever chemicals" that leak from our homes, factories and waterways into the sea.
A decades-old proof showed that seven shuffles are enough to mix up a deck of cards. But it requires you to cut the deck with the precision of a professional magician. A new proof gets around that obstacle. The post Seven Perfect Shuffles Randomize a Deck of Cards. But How Many Sloppy Ones? first appeared on Quanta Magazine
Scientists have taken a surprising step toward unlocking regeneration in mammals, showing that the ability to rebuild complex body parts may not be lost after all—it may simply be switched off. Using a two-stage treatment, researchers redirected the body’s normal healing response away from scar formation and toward regrowth, successfully restoring bone, joints, ligaments, and tendons after amputation in animal studies.
Southwest Research Institute (SwRI) is developing electronics and flight software for the NASA/U.S. Geological Survey (USGS) Landsat 10 satellite, which is set to launch in 2031 to collect new and improved Earth observation data. The mission continues NASA's and USGS's partnership on the ongoing Landsat program, which has launched nine satellites since 1972 and provided more than 10 million images of Earth's surface.
American Indians and Alaska Natives living below the poverty line face sharply higher rates of food insecurity than other impoverished adults—nearly 4 in 10 lack consistent access to a healthy diet.
