Reducing calorie intake has extended lifespan in animals including mice, rhesus monkeys, and fruit flies. In some studies, the animals also remained healthier for longer. But severe calorie restriction can come with serious costs. Mice placed on a diet with 40% fewer calories, for instance, become more vulnerable to infections,…
Pangolins look almost prehistoric. These medium-sized mammals, found only in Africa and Asia, have long, powerful tails, large curved claws, and bodies covered in overlapping scales that resemble a pinecone. Those distinctive scales are also a major reason pangolins are in danger. They are heavily targeted by poachers and are…
An international team of researchers, led in part by the University of Ottawa, has documented a major calving event at Petermann Glacier in northwest Greenland. On August 4, 2026, the glacier released a 76.4 km2 ice island, its largest loss of floating ice since 2012 and the biggest Arctic calving…
Could how much sugar you consumed before your second birthday shape your health decades later – even into your 70s? A new study that my colleagues and I conducted suggests the answer could be yes. People who had less sugar exposure during the first few years of life were much…
Curcumin, the natural compound responsible for turmeric’s vivid yellow color, is widely studied for its anti-inflammatory and antioxidant properties. New research in rats suggests it may also help protect blood vessels from damage linked to diabetes. The findings were presented at the 2026 American Physiology Summit in Minneapolis. The Summit…
NASA’s Nancy Grace Roman Space Telescope is now one major step closer to liftoff. On Aug. 21, teams enclosed the observatory inside the protective fairing of its SpaceX Falcon Heavy rocket at the Payload Hazardous Servicing Facility at NASA’s Kennedy Space Center in Florida. The fairing is the large shell…
An international team led by the University of Bern has found evidence that a single asteroid collision may have dramatically reshaped Deimos, the smaller of Mars’ two moons. By combining detailed computer simulations with recent images from ESA’s Hera spacecraft, the researchers concluded that one impact could account for both…
Children who spend more time indoors looking at screens and less time outside are more likely to develop myopia, also known as nearsightedness. The problem is growing rapidly worldwide, with some experts estimating that nearly 5 billion people (or 50% of the world population) could be nearsighted by 2050. New…
Severe stress during childhood can increase a person’s vulnerability to anxiety, depression, and other mood disorders when new challenges arise later in life. Scientists at Washington University School of Medicine in St. Louis and Princeton University have now identified a biological process that may help explain how early trauma can…
Low-carb diets have become increasingly popular, but their effects on cholesterol are far from uniform. Some people see little change, while others experience a substantial increase. New research suggests that genetics may help explain why. The findings indicate that saturated fat, which can make up a larger share of some…
For about a century, scholars studying the Assyrian Empire have treated the Assyrian King List (AKL) as the standard record of the kingdom’s rulers and the order in which they reigned, particularly during the later phases of Assyrian history. A recent study in the Journal of Cuneiform Studies, titled “Three…
What we experience when making a decision may be very different from what actually happens inside the brain, according to Indiana University Professor Tom James. For decades, both scientific theories and everyday intuition have tended to describe decision-making as a sequence. First we perceive something, then we think about it…
Scientists have found a new explanation for why Antarctica became covered in ice millions of years before the Arctic. The international study, published in Science, addresses a long-standing climate mystery: how Antarctica could develop a massive ice sheet at a time when Earth was around 5ºC warmer than it is…
Older adults who received a shingles vaccine after entering a skilled nursing facility were less likely to be diagnosed with dementia over the following four years, according to a new study. Researchers found that vaccinated adults had a 24% lower risk of dementia compared with those who did not receive…
Cell therapies that harness the immune system have transformed treatment for some cancers of the blood and lymphatic system. Solid tumors, however, have remained much more difficult to treat because they are harder for immune cells to enter and can release signals that weaken nearby immune defenses. Researchers at Stanford…
Europe’s Copernicus Sentinel-1 mission has documented a major change at Petermann Glacier in northwest Greenland, where a 76 sq km section of the glacier’s floating ice tongue broke away on August 4, 2026. The break represents Petermann Glacier’s largest loss of floating ice since 2012 and the biggest calving event…
Lignin gives plants much of their structural strength and represents the largest renewable source of aromatic chemicals found in nature. It can make up a substantial share (up to 35%) of waste biomass from agriculture and forestry. Yet lignin’s complicated molecular structure makes it notoriously difficult to break apart efficiently,…
A human, an octopus, and a coral may appear to have almost nothing in common, but their chromosomes still contain recognizable fragments inherited from an animal ancestor that lived more than 600 million years ago. Researchers at the University of Vienna have now traced how those ancient genomic pieces were…
NASA scientists say some microbes carried into space by human explorers may be able to survive in sheltered, shadowed areas near the Moon’s South Pole. The findings, published on Aug. 19, 2026, in Science Advances, underscore the importance of understanding how long Earth microbes can persist in extreme lunar environments.…
Most of the brain’s roughly 100 billion neurons are produced before birth. However, the small number of new neurons that continue to form in the adult hippocampus may play an important role in protecting against depression, according to new research from Columbia University Vagelos College of Physicians and Surgeons. The…
People who live to exceptionally old ages may retain an immune system that continues adapting to new threats. Researchers have found that supercentenarians, people who reach age 110 or older, carry unusually high levels of specialized immune cells called CD4 cytotoxic T lymphocytes (CD4 CTLs). These cells have previously been…
Gravity is best known as the force that pulls objects toward Earth, but its role extends far beyond falling apples. Across the universe, gravity acts as an invisible framework that influences how galaxies, galaxy clusters, and the largest cosmic structures form and evolve. For decades, however, astronomers have faced observations…
Medications can influence the community of microbes living in the human gut long after a person stops taking them, according to a large study led by researchers at the University of Tartu Institute of Genomics. The findings suggest that a person’s prescription history may help explain differences in the gut…
Backyard bird feeding is one of our country’s most popular pastimes. Research reveals about half of Australian households feed wild birds, with many people doing so daily. However, this practice could act as a superspreader event – where a disease infects an unusually high number of people or animals –…
For billions of years, an ancient cluster of stars has been gradually coming apart, shedding stars that now form a faint, narrow ribbon across space. That delicate structure is offering astronomers a new way to investigate one of the universe’s biggest mysteries. An international research team, including an astrophysicist from…
A microchip about the size of a grain of rice can generate a highly organized “rainbow” of light, a capability that could eventually support faster, higher-capacity 6G communications and extremely precise timing for quantum technologies. Physicists at Loughborough University, working with an international research team, demonstrated a system that produces…
A new analysis of biological aging across the human body suggests that both sleeping too little and sleeping too much are associated with faster aging in the brain, heart, lungs, immune system, and other organs. These sleep patterns were also linked to a broad range of diseases. “Previous studies have…
Screens are now a routine part of life for many young children, raising growing questions about how early exposure could influence development over time. New longitudinal research that tracked children from age 1 through age 8 found that greater screen viewing, especially during infancy and around the time children begin…
Quantum mechanics has long challenged the familiar idea that an object must occupy one precise place at a given moment. Fundamental particles such as electrons are instead described by a “wavefunction,” a mathematical representation that researchers can use to calculate the probabilities of properties such as position and momentum. Inside…
NASA’s Nancy Grace Roman Space Telescope has passed an important milestone ahead of its trip to space. Mission leaders from NASA, the Roman Space Telescope team, and SpaceX met Friday at Kennedy Space Center in Florida for a Flight Readiness Review. During this formal assessment, teams examined the spacecraft, rocket,…
