In an epidemic of online misinformation, experts look to artificial intelligence to help sort fact from fiction

Disturbances in this critical sense are often linked to problems with brain health, researchers are learning

There’s an urgent need to study how artificial intelligence makes ethical choices because it soon will make many such decisions in our stead, says computer scientist Iyad Rahwan

Inks created with a patient’s own cells might one day help the body regrow tissues

Slow-healing lesions — common in diabetics and burn victims — can lead to lingering infections that resist antibiotic treatment. A new approach using light-activated therapies may offer a solution.

As temperatures rise, it is the poor who suffer most. The coping strategies of those living in informal settlements may hold lessons for cities of the future.

Neuroscientists are discovering that spending time with others may be a basic biological necessity, like need for food or water

Critters that dine on flesh and waste also consume the animal’s DNA. That genetic material is helping scientists detect and map elusive species and their pathogens.

Scientists are exploring new algorithms, hardware and computing methods to lower AI’s power demands. Strategic siting of data centers and other steps to increase green energy use are also key.

As temperatures rise, some creatures pick fights while others struggle to learn. The consequences of these behavioral changes may ripple through ecosystems.

People with a rare genetic disorder that damages the amygdala are helping neuroscientists rethink how the brain shapes fear, trust and concern for others

Researchers are testing CAR T cell therapy as a way to reset the immune system in lupus, Graves’ disease and other conditions where the body’s defenses go rogue

Species are disappearing at least 10 to 100 times more rapidly today than extinctions observed over millions of years. A biologist says the answer is reciprocity — to give to the planet and not just take.

Evidence is growing from rodent studies that sperm carries marks of a father’s life experiences, influencing traits in offspring. Bits of RNA could be the drivers of these epigenetic effects.

Huge snakes, tiny snakes, poisonous snakes and constrictor snakes, snakes that slither, burrow or swim: New fossils and modern technology are tracing serpent origins

Changes in neural connections due to substance use and withdrawal are long-lasting, and craving can peak well into abstinence. Understanding this process could inspire drugs to support recovery.

Nostalgia plays a big role in the meals that bring us solace — which mean we might be able to recondition ourselves toward healthier foods that still soothe

Once global warming peaks, it could take centuries to cool things back down. But we can bend the curve by cutting fossil fuel emissions now.

As the number of long-term survivors grows, doctors and patient advocates are working to improve post-cancer care

Turrets and tunnels and carbon dioxide — oh my! These ants farm, but they are also master builders.
