Artificial intelligence is rapidly learning to autonomously design and run biological experiments, but the systems intended to govern those capabilities are struggling to keep pace. AI company OpenAI ...

Our brains keep on whirling long after we drift off to sleep. Each night, the hippocampus, a major hub for learning, replays experiences from the previous day and etches them into memory. And even in ...

We are entering the third phase of generative AI. First came the chatbots, followed by the assistants. Now we are beginning to see agents: systems that aspire to greater autonomy and can work in ...

AI has aced medical exams, but there's a wide gap between tests and the real world. A new study suggests the divide is closing. Emergency doctors make high-stakes decisions in fast-paced, often ...

For all their promise, electric cars have always had a big drawback: Charging takes much longer than filling up a gas tank. But the gap has been closing, and this week, Chinese battery giant CATL ...

Few cancer treatments are as ferocious as CAR T cell therapy. Often derived from a patient’s own immune cells, CAR T cells are genetically modified to hunt down and destroy cancer cells. The FDA has ...

Modern AI chatbots can do amazing things, from writing research papers to composing Shakespearian sonnets about your cat. But amid the sparks of genius, there are flashes of idiocy. Time and again, ...

A US Senate committee has directed NASA to begin work on a moon base “as soon as is practicable.” Under legislation advanced by the Senate lawmakers, the outpost would serve as a science laboratory ...

The tiny chips hitch a ride on immune cells to target inflammation in the brain. Scientists hope to kick off clinical trials within three years. From restoring movement and speech in people with ...

It’s now possible to treat inherited blood diseases, such as sickle cell disease, with gene editing. Blood stem cells are extracted from the patient, modified, and infused back into their bone ...

Our bodies are constantly breaking down. Over time, their built-in repair mechanisms also fail. Knee cartilage grinds away. Hip joints no longer support weight. Treatments for breast cancer and other ...

Scientists just unveiled the world’s tiniest pacemaker. Smaller than a grain of rice and controlled by light shone through the skin, the pacemaker generates power and squeezes the heart’s muscles ...
