Humans’ capacity to endure heat stress may be lower than previously thought — bad news as climate change leads to more heat waves around the globe. | Continue reading
The measurement helps refine the dividing line between neutron stars and black holes. | Continue reading
“Ice stupas” emerged in 2014 as a way to cope with climate change shrinking glaciers. Automation could help improve the cones’ construction. | Continue reading
Scientists are developing quantum communications networks on Earth. Aliens, if they exist, could be going further. | Continue reading
Starlet sea anemones use speedy projectiles to sting predators and prey. New images capture a detailed look at these weapons in action. | Continue reading
Computer simulations reveal that two types of friction are important in determining how quickly dominoes collapse. | Continue reading
The Supreme Court’s scrapping of Roe v. Wade shifts decisions about related health care to states. Accurate science is often missing in those talks. | Continue reading
Long-sought clumps of four neutrons called tetraneutrons last less than a billionth of a trillionth of a second, an experiment suggests. | Continue reading
Gaia’s new data can tell us about galaxies the Milky Way has swallowed, the young solar system and asteroids that could hit Earth. | Continue reading
Samples Hayabusa2 brought to Earth from asteroid Ryugu are far fresher than similar types of meteorites that scientists have found. | Continue reading
A new study analyzes a Denver program that sends a mental health professional and EMT to handle trespassing and other minor crime offenses. | Continue reading
Dogs can be trained to sniff out COVID-19 cases. They’re overall as reliable as PCR tests and even better at IDing asymptomatic cases, a study suggests. | Continue reading
The Frontier supercomputer at Oak Ridge National Laboratory in Tennessee clocked in at more than 1.1 quintillion calculations per second. | Continue reading
Unfamiliar voices hold special appeal for teens, a sign of a shift from a focus on mostly family to wider networks, brain scans suggest. | Continue reading
Though musk oxen are built to bash, a study of the headbutters turned up signs of brain damage. But that may not be catastrophic for the bovids. | Continue reading
Scientists have detected adenine and guanine in meteorites for decades and seen hints of uracil. But cytosine and thymine had remained elusive. | Continue reading
Neptune's atmospheric temperatures show a global drop and later, a weird isolated spike at the south pole. Scientists don't yet know why. | Continue reading
Finding the missing 8 percent of the human genome gives researchers a more powerful tool to better understand human health, disease and evolution. | Continue reading
New evidence that Spinosaurus and its kin hunted underwater won't be the last word on whether some dinosaurs were swimmers. | Continue reading
Images from the New Horizons spacecraft suggest that light from all known galaxies accounts for only half of the cosmos’ visible background glow. | Continue reading
Science paved the way for antibiotics, lasers, computers and COVID-19 vaccines, but science alone was not enough. | Continue reading
The events of our lives are reflected in the size, shape and behavior of our constantly changing brains. The effects of COVID-19 changes aren’t clear. | Continue reading
Wind and gravity compete to make some raindrops go up while others slide down, a mathematical analysis suggests. | Continue reading
A one-time, gene-based treatment for hemophilia increased the amount of a necessary blood clotting protein in men with a severe form of the disease. | Continue reading
Folds in the plasma that streams from the sun might trick the eye into seeing the well-defined arches, computer simulations of the solar atmosphere show. | Continue reading
The EPA also OK’d more trials in Key West, Fla. Both states now get their say in whether to release free-flying Aedes aegypti to sabotage their own kind. | Continue reading
The bones of more than 100 cadavers are shedding light on a more precise and reliable way to determine when someone died. | Continue reading
The digital revolution has brought chess-playing robots, self-driving cars, curated newsfeeds — and new ethical challenges. | Continue reading
A hierarchical structure of micropillars and nanopores allows the tail to break away when necessary while preventing it from easily detaching. | Continue reading
A re-creation of a 3,000-year-old horseman’s trousers helped scientists unravel its complex origins. | Continue reading
The stories of the women who assembled integrated circuits and wove core memory for the Apollo missions remain largely unknown. | Continue reading
