Scientists have discovered chemically confirmed traces of ancient blood inside 115-million-year-old dinosaur bones, challenging assumptions about how long biological molecules can survive. The extraordinary preservation could unlock new clues about dinosaur physiology and even help scientists search for ancient life elsewhere in the universe.
What happens when a technology becomes more powerful than its creators can fully understand?
A study of nearly 5,800 adults found that heart scans measuring calcium buildup in the arteries led to the same observed rate of major cardiovascular events as traditional risk assessments, despite recommending statins to far fewer patients. Surprisingly, patients advised to take statins based on their scans were nearly three times as likely to stick with their medication, raising intriguing questions about how doctors should identify and treat heart disease risk.
The risk of relying on uncertain carbon removal projects can now be quantified using a new standardized metric that can be applied across all such schemes, irrespective of the technology used.
University of Oregon geologist Becky Dorsey's latest research sheds light on the Siculo-Calabrian rift zone, a belt of faults spanning more than 100 miles (160 kilometers) in southern Italy. The new data could help improve earthquake hazard assessment in this seismically active region.
An international team of scientists has outlined how a new generation of artificial intelligence models could transform our understanding of ecosystems and help predict their responses to environmental change.
Living cells are one of the few materials that can replicate themselves, and this is crucial for tissue development and recovery from injury or illness. But making sure cell division only happens at the right time is essential; otherwise, unregulated replication can lead to problems like cancer.
Scientists have solved a mystery surrounding destructive beetles attacking blueberry bushes in North Carolina, identifying a species whose massive larvae can grow up to five inches long and destroy plant roots. Although farmers have reported damage for more than a decade, the insects responsible remained unidentified until researchers used DNA analysis to uncover the culprit.
After his mother was killed in a bear attack in Kashmir, Indian software engineer Mudasir Ali developed an online early-warning system to help people in the Himalayan region avoid dangerous encounters with wildlife.
November's night sky is packed with celestial wonders, from bright meteor fireballs and a close pairing of Mars and Jupiter to a spectacular supermoon. Meanwhile, NASA's Voyager 1 is making history by becoming the first spacecraft to reach a distance of one light-day from Earth.
After nearly 22 years of exploring the universe’s most violent explosions, NASA’s Swift Observatory has re-entered Earth’s atmosphere over Indonesia. Originally designed to last just two years, the pioneering space telescope transformed our understanding of black holes, exploding stars, and mysterious cosmic outbursts.
Full-fat dairy may not be the health villain it has long been portrayed as, according to a new study finding that three daily servings did not worsen weight, cholesterol, or insulin resistance over 12 weeks. Researchers also observed improvements in blood pressure and nutrient intake, raising questions about longstanding recommendations to choose low-fat dairy.
ACF's latest report, "Bulldozers and Broken Promises," an investigation into deforestation, has ruffled a few feathers. But someone has to do it. Why? Because deforestation is a huge problem in Australia.
With global warming set to exceed 1.5°C, adaptation finance falls far short of needs, implementation is constrained by institutional barriers, and losses and damages are mounting, according to a new report from the United Nations Environment Programme (UNEP).
Yale College junior Leah Mock did fieldwork in a remote quarry in western Colorado that exposes the 50-million-year-old Green River Formation.
Researchers at Karolinska Institutet have discovered how a protein called TACO1 helps mitochondria produce proteins when the process encounters difficult sequences. The study, published in Nature Communications, provides new insights into a mechanism that is disrupted in some mitochondrial diseases.
A surprising new discovery suggests that some dead stars can grow far more massive than scientists once thought possible. Computer simulations show that powerful magnetic fields could allow white dwarfs to reach 2.4 times the mass of the Sun, dramatically exceeding a famous limit that has stood for decades. The findings could help explain unusually bright supernova explosions that have long puzzled astronomers.
Assisted suicide is morally and ethically controversial. Public debate on the topic tends to arise primarily when a high-profile case comes to light—as was most recently the case with the famous twins Alice and Ellen Kessler. While assisted suicide is permitted in Germany, it is scarcely regulated by law. Until now, there has been little scientifically validated data on the current practice of assisted suicide.
Among the technical inquiries spanning topics like cyclodextrin polymers and mass spectrometry that were stacked in Damian Helbling's inbox was a question about four golden retrievers.
A new study reveals narrow-clawed crayfish, an understudied invasive species in the U.K., to be as aggressive as the well-known signal crayfish.
