When people who own dogs are stressed, their dogs also get stressed, a new study suggests. It’s another indication of how emotionally synchronized dogs and their humans can be.
Giant gyres of plastic in the ocean grab headlines, but it’s the tiny bits of plastic that scare scientists. And they’ve made their way everywhere, a new study finds – including our seafood.
Move over, fruit flies, rats and zebrafish. Squid and octopuses have elaborate brains and behaviors, and scientists say studying them in the laboratory could yield important biological insights.
The conventional wisdom is that city life makes you fat and rural life keeps you trim. A new study looks at the numbers to see if that holds true.
The next phase of human evolution seems headed toward merging biological bodies with machines, and in the first video of Future You, Elise Hu gets connected to a network and plays a game her thoughts.
Ethical concerns aside, the genetic ingredients for human traits are so complex that editing a few embryonic genes is unlikely to have much effect — or achieve the fantasy of enhancing humans.
A fictitious asteroid is the focus of a realistic exercise, as experts at the Planetary Defense Conference run through how the Earth would respond to news of a looming asteroid strike.
SPRINGFIELD, Ohio (AP) – Researchers will expand testing of defense-related drone technology with new permission to fly beyond their line of sight in a limited area of Ohio. The Federal Aviation Administration authorized that after the U.S. Air Force Research Laboratory and the state developed new technology called SkyVision, which functions as sort of air… Read More
It’s the only repellent that drives mosquitoes away when they come in contact with it. A new study has a theory about why that is.
Scientists have found a way to transform electrical signals in the brain into intelligible speech. The advance may help people paralyzed by a stroke or disease, but the technology is experimental.
This could be a crucial year for the powerful gene-editing technique CRISPR as researchers start testing it in patients to treat diseases such as cancer, blindness and sickle cell disease.
Scientists are learning how the party drug ketamine relieves depression so quickly — and why its effects fade over time.
“For the first time we have seen what we thought was unseeable,” said Event Horizon Telescope Director Shep Doeleman, as the first image of a black hole was released.
Deep brain stimulation offers relief from some neurological problems and is being tested for mood disorders. But the treatment — an implant in the brain — raises ethical questions.
Some panel members said they don’t agree that breathing sooty air can cause premature death. The panel’s draft recommendations to the EPA would change how it assesses the dangers of air pollution.
The twin sites in the Laser Interferometer Gravitational-Wave Observatory are about to go back online. New hardware should make them able to sense more colliding black holes and other cosmic events.
Last year, China drastically cut back its imports of plastic waste to recycle. Now the U.S. and other wealthy nations must figure out what to do with their discards.
Researchers think genetically engineered versions of microbes that can live in humans could help treat some rare genetic disorders and perhaps help with Type 1 diabetes, cirrhosis and cancer.
Getting DNA into plant cells is tricky. Researchers have tried using infectious bacteria, as well as gene guns that shoot gold bullets. Then a physicist came up with a new approach almost by accident.
British doctors report the apparent eradication of HIV from a patient who was undergoing treatment for cancer. It’s only the second time this has been accomplished, despite many attempts.
Researchers are learning that attitude can have measurable effects on health. For a food allergy therapy, thinking of stressful side effects as positive signals helped patients complete the treatment.
Most patients do fine, research suggests, when the lead surgeon steps away to begin another procedure. But patients who are older or have underlying medical conditions sometimes fare worse.
The insects were created, using CRISPR, to carry a powerful “gene drive.” The mosquitoes could provide a potent weapon against malaria, but they raise fears about unpredictable environmental effects.
NASA’s six-wheeled rover landed on the red planet in January 2004 for what was billed as a 90-day mission. The plucky robot was still going until a dust storm on Mars last summer killed it.
Researchers say the metabolism of a woman’s brain remains higher than a man’s throughout a lifetime. And that may help with late-life creativity and learning.
