The technology exists to build autonomous weapons. How well they would work and whether they could be adequately controlled are unknown. The Ukraine war has only turned up the pressure.
People don’t all age at the same rate. Untangling the factors that influence health and disease – such as epigenetics, demographics and behavior – could lead to better care for those who need it most.
Black, Latino, Asian and Indigenous teens have different online experiences – both positive and negative – than their white peers. These differences are overlooked when research focuses on white kids.
Fossil evidence of how the earliest life on Earth came to be is hard to come by. But scientists have come up with a few theories based on the microbes, viruses and prions existing today.
The slow release of information about the chemical spill and results of air and water tests have left many questions about the risks and long-term impact.
If you want to use an exoskeleton to improve balance, a study finds that superhuman reflexes can help you stay upright.
There are thousands of sightings of UFOs – or ‘unidentified aerial phenomena’ as the US government prefers to call them – every year.
Evidence in Earth’s natural archives, from tree rings to seafloor sediments, points to one trend. Some climate models suggest another.
The idea that scientists could warn a region that a big quake was coming at a certain time – with enough advance notice for large-scale preparation and evacuation – remains a dream, not a reality.
Vital records document the birth, death, marriage and divorce of every individual. A more centralized system in the US could help public health researchers better study pandemics and disease.
Lab testing provides doctors with essential information to help them diagnose and treat disease. Here’s what happens behind the scenes after you roll up your sleeve for a blood draw.
How do you determine whether one brand is similar enough to another to infringe on its trademark? Researchers propose that comparing brain scans could be an option.
An astronomer takes us on a tour of the universe to learn about the birth of stars and planets and how they get their spin.
An epigenetic model of cancer that incorporates the concept of stochasticity could also explain why cancer risk increases with age and how biological development can be reversible.
Twitter was blocked in Turkey for about 12 hours at the height of rescue and relief efforts in the aftermath of a massive earthquake, severely hampering a vital tool for disaster response.
Kids need to learn when little lies are the right choice. But research suggests parents may not be clear in the messages they send about how they value the truth.
Twitter has long allowed anyone to access its data about who tweeted what and when. This has been a boon to research, from public health to criminology. The new fees put that research at risk.
Narcissists, psychopaths and Machiavellians, oh my. These antagonistic personality types can make life hard for the people around them. Here are five tips for how to deal with them at work.
Cells degrade and recycle damaged parts of themselves through a process called autophagy. When this “self-devouring” goes awry, it may promote cancer and neurodegenerative disease.
Scientists are learning that diversity has many perks – whether in multispecies groups of animals or human society.
Annual flu vaccines are in a constant race against a rapidly mutating virus that may one day cause the next pandemic. A one-time vaccine protecting against all variants could give humanity a leg up.
Atmospheric rivers can melt fragile new sea ice. When these storms arrive in waves, the sea ice doesn’t have a chance to recover.
There’s a lot of interesting science behind the fermenting, roasting, grinding and melting that turns chocolate into the bars, bonbons and baked goods you know and love.
Birds and dinosaurs lived together for millions of years, but only toothless birds survived the asteroid impact that upended life on Earth.
