Latest science news, discoveries and scientific developments.
NASA’s Perseverance rover has set a historic record by traveling 28.10 miles across Mars, farther than any vehicle has ever driven on another world. Armed with groundbreaking autonomous navigation technology and increasingly advanced driving capabilities, the rover is pushing the boundaries of robotic exploration.
Ebola outbreak crosses grim milestone, artificial intelligence solves major math problems, and scientists caution against making daylight saving time permanent
NASA satellites have captured an eerie, skull-shaped formation on a remote Antarctic island, but its haunting appearance conceals a troubling warning about melting glaciers. Unusually warm winter temperatures have exposed large areas of dark ice, potentially accelerating future melting and gradually transforming the skull's ghostly features.
Scientists have uncovered surprising DNA evidence that Europeans living more than 30,000 years ago were connected across vast distances, challenging the idea that ancient populations remained largely isolated. Genetic clues from human remains and cave sediments reveal prehistoric migration, long-lasting communities, and survival through the harshest conditions of the Ice Age.
A major new study challenges the idea that moderate drinking is safe, finding that even relatively small amounts of alcohol increase the risk of cancer, heart disease, and premature death. Researchers found no overall health benefits from drinking and warn that consuming more than one alcoholic beverage per day can significantly increase long-term health risks.
NASA’s Hubble and James Webb Space Telescopes have uncovered surprising clues about the solar system’s origins by studying 27 tiny, distant objects beyond Neptune. Scientists discovered that these ancient building blocks of planets have remained remarkably unchanged for billions of years, while their unexpected sizes and numbers challenge existing theories of planet formation.
A major new review challenges the growing enthusiasm for medical cannabis as an insomnia treatment, finding little reliable evidence that it improves sleep quality, sleep duration, or daytime functioning. Researchers caution that this doesn't mean cannabis is ineffective, only that existing studies are too weak to establish whether it works.
For decades, discussions and decisions about access to contraception, abortion, maternal health care, HIV prevention and treatment, comprehensive sexuality education, gender equity and protection from sexual violence have largely flowed in one direction: from the Global North to the Global South.
When we hear that climate change is damaging natural environments, it conjures images of rising seas eroding coastlines, or heat waves bleaching the Great Barrier Reef. But what about deserts?
A University of Bath–led study has estimated that the carbon dioxide produced by humans as our bodies turn food into energy rose by 74% between 1985 and 2015, reaching 2.05 billion metric tons a year. Researchers say the findings could help scientists better understand where carbon comes from, where it goes and how human activity fits into the bigger picture.
Tucked away among its sensors, cameras and navigation tools, NASA's Mars rover Perseverance is wearing small swatches of spacesuit material. A rover doesn't need a spacesuit, but the swatches—each less than a square inch (6.5 square centimeters) in size—serve an important purpose: They're helping scientists assess the potential damage caused by ubiquitous Martian dust.
Authorities in New Delhi stepped up anti-pollution measures on Sunday, including higher parking fees and work-from-home orders, seeking to curb toxic smog in one of the world's most polluted capitals.
Long dubbed an "air-conditioned nation," Singapore is experimenting with cooling alternatives from chilled beams to "passive displacement" to curb its thirst for energy-guzzling air conditioning.
Guided by the beam of a flashlight, Tino Marolo follows his dog Stella through the darkness of a Piedmont woodland, searching for one of Italy's most prized culinary treasures hidden beneath the soil.
Nowhere in the Iberian Peninsula or the Balearic Islands has a tropical climate—for this to be the case, the average temperature in the coldest month would have to be 18°C (64 degrees Fahrenheit) or higher. The contrast between Spain's winters and summers, and the low temperatures reached in winter, do not resemble those of any tropical climate.
In a study spanning 192 sites and four continents, researchers have discovered that conifers planted in the Southern Hemisphere grow up to four times faster and are more drought-resistant than those growing in their native ranges.
Sleep is fundamental to well-being. Decisions to end semiannual clock changes and remain on permanent daylight saving time (DST) in British Columbia, the Northwest Territories, Alberta, Manitoba and northwestern Ontario have consequences for many Canadians due to potential sleep disruption.
The interstellar comet 3I/ATLAS carries a chemical clue to conditions in the planetary system of its origin, locked away long before it reached our sun. Its methane signature is unusually rich in heavy hydrogen, suggesting that the comet's frozen ingredients took shape in an intensely cold environment around another star—or in the cloud that preceded it.
What materials did ancient Egyptians use to preserve the dead, and how can their composition still be investigated thousands of years later? An interdisciplinary team at Marburg University has combined modern natural product analysis with Egyptology and the history of pharmacy to investigate these questions.
A surprising new study suggests that eating peanuts every day could help support brain health and memory in older adults. Researchers found that consuming about two servings of unsalted, skin-roasted peanuts daily for 16 weeks improved insulin responsiveness in brain regions important for memory, a function that often weakens with age and has been linked to Alzheimer's disease.
