The Earth supports the only known life in the universe, all of it depending heavily on the presence of liquid water to facilitate chemical reactions. While single-celled life has existed almost as long as Earth itself, it took roughly three billion years for multicellular life
Astronomers have taken a fresh look at the famous “Hand of God” pulsar, combining X-ray data from NASA’s Chandra Observatory with new radio observations from the Australia Telescope Compact Array. At the center is pulsar B1509-58, a rapidly spinning neutron star only about 12
Satellite tracking of New Zealand southern right whales, or tohorā, has revealed a key feeding location about 500kms south of Australia that needs to be protected, University of Auckland scientists say.
Australia's workforce is almost evenly split between men and women. Yet fewer than one in four Australians work in a gender-balanced occupation.
Imagine you're hiring someone for a job that requires a very kind, agreeable and co-operative person. You have two candidates and all you know about them are their names: Renee and Greta. Who do you think would be a better fit?
A breakthrough pill, baxdrostat, has shown remarkable success in lowering dangerously high blood pressure in patients resistant to standard treatments. In a large international trial, it cut systolic pressure by nearly 10 mmHg, enough to significantly reduce risks of heart
Beta blockers, used for decades after heart attacks, provide no benefit for patients with preserved heart function, according to the REBOOT trial. The massive study also found women faced higher risks when taking the drug. Experts say the results will change heart treatment
There are few symbols of the American West more iconic than the bison—shaggy giants that once roamed in the tens of millions before being nearly annihilated by European settlers.
A plant's number one priority is to grow—a feat that demands sunlight, nutrients, and water. If just one of these three inputs is missing, like water in a drought, growth halts. You might then think that at the end of that drought, the plant would jump right back into growing.
For millennia humans have tried to scare wolves away from their livestock. Most of them didn't have drones.
Previously, research on controlling gene networks has been carried out based on a single stimulus-response of cells. More recently, studies have been proposed to precisely analyze complex gene networks to identify control targets.
In a major leap for artificial intelligence (AI) and photonics, researchers at the University of California, Los Angeles (UCLA) have created optical generative models capable of producing novel images using the physics of light instead of conventional electronic computation.
A machine-learning algorithm spotted signs of “covert consciousness” in coma patients—in some cases, days before doctors could do so
Stanford researchers reveal meandering rivers existed long before plants, overturning textbook geology. Their findings suggest carbon-rich floodplains shaped climate for billions of years.
The climate benefits of planting trees may have been greatly overestimated, but swift action could ensure reforestation meets its potential to curb dangerous emissions, new research has found.
Hundreds of thousands of people are at risk of losing homes, businesses—and lives—as giant “gullies” expand into cities across Africa
As the Great Salt Lake shrinks, scientists are uncovering mysterious groundwater-fed oases hidden beneath its drying lakebed. Reed-covered mounds and strange surface disturbances hint at a vast underground plumbing system that pushes fresh water up under pressure. Using
New research suggests that exercise may not just make us feel younger—it could actually slow or even reverse the body’s molecular clock. By looking at DNA markers of aging, scientists found that structured exercise like aerobic and strength training has stronger anti-aging
Drinking nitrate-rich beetroot juice lowered blood pressure in older adults by reshaping their oral microbiome, according to researchers at the University of Exeter. The study found that beneficial bacteria increased while harmful ones decreased, leading to better conversion of
