Your dislike of eating bugs may be 9,000 years old

As the global population grows and climate change places increasing pressure on food systems, researchers and policymakers are looking more closely at alternative sources of nutrition. Insects are one possible option. A total of 1,611 insect species are classified as edible, and organizations including the Food and Agriculture Organization of…

Eating more ultra-processed foods may raise prostate cancer risk by 30%

Ultra-processed foods (UPFs) now supply nearly 60% of the calories consumed by adults in the United States and about 70% of those consumed by children. These industrially produced foods include soft drinks, packaged cereals, snacks, and processed meats. They are typically made with refined fats, oils, sugars, starches, salts, and…

Vitamin C won’t prevent most colds, but it may do one small thing

From the first hint of cold winter mornings, supermarkets and pharmacies begin heavy marketing to coax us to stock up on vitamin C to get through the cold and flu season. But where did that idea come from? As we’ll see, it’s a story including a Nobel Prize winner, a…

A mysterious cosmic hum may come from 13-billion-year-old dark stars

A faint background of extremely low frequency gravitational waves detected through networks of pulsars could contain clues to events that unfolded more than 13 billion years ago, including the emergence of some of the Universe’s earliest supermassive black holes. In a study published as a Letter in Physical Review D,…

Scientists switch on a strange new form of magnetism in an ultrathin material

A recently proposed form of magnetism known as altermagnetism could eventually help researchers make computer memory smaller, faster, and more efficient. Now, scientists have found evidence that ruthenium dioxide, a quantum material previously considered nonmagnetic in its bulk form, may display this unusual magnetic behavior when prepared as an ultrathin…

324-million-year-old fossil reveals how insects conquered land

The rise of complex ecosystems on land was one of the major turning points in the history of life. As organisms expanded beyond the oceans, terrestrial environments became home to increasingly diverse communities. Insects, which today make up the most species-rich animal group on Earth, eventually became central to these…

Smart nanoparticles light up brain cancer and destroy what surgery misses

Glioblastoma is considered the most aggressive type of brain cancer. One reason it is so difficult to treat is that cancer cells spread into nearby brain tissue. That makes complete surgical removal extremely challenging because surgeons must avoid damaging healthy areas of the brain. The blood-brain barrier creates another obstacle…

Scientists discover a brain “brake” that can shut down chronic pain

Deep inside the brain, a small group of nerve cells helps control how strongly pain signals are felt. Under normal conditions, this system can suppress pain traveling through the spinal cord. After nerve damage, however, the same circuitry can become overactive and help sustain chronic pain. Researchers at Washington University…

Scientists may have found a shortcut to calorie restriction’s anti-aging benefits

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,…

190-year-old DNA reveals a hidden pangolin species

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…

Manhattan-sized ice island breaks off Greenland’s Petermann Glacier

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…

What you eat before age 2 may affect your health 70 years later

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…

Turmeric compound may protect blood vessels from diabetes damage

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 Roman Space Telescope is ready to hunt thousands of alien worlds

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…

One asteroid strike may explain two mysteries of Mars’ moon Deimos

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…

A missing color in indoor light may help prevent myopia

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…

Childhood trauma may leave a lasting “scar” inside brain cells

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…

Your genes may decide whether a low-carb diet sends cholesterol soaring

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…

Three forgotten kings could rewrite the history of ancient Assyria

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…

Your brain may not actually “make” decisions

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…

Forces deep inside Earth helped Antarctica freeze before the Arctic

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…

Shingles vaccine linked to 24% lower dementia risk

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…

Supercharged “natural killer” cells could be a powerful new cancer weapon

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…

A Manhattan-sized ice island just broke free from Greenland

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…

Atomic catalyst unlocks the hidden value of plant waste

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,…

Scientists find hidden “highways” guiding animal evolution

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 finds Earth microbes could survive on the Moon

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.…

Depression may shut down the brain’s ability to make new neurons

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…
