The bacteria grew, thrived, and divided for hundreds of generations. But they were unlike any other living creatures on Earth. These synthetic cells, called Ec19, were the first to have had one ...

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 ...

It's a step change in cybersecurity. Exploits that would take experts weeks to develop can now be generated in hours. Concerns about AI's ability to turbocharge cybersecurity threats have been ...

In a step toward biological computing, brain organoids rewired their networks as they learned to balance a digital pole on a cart. Try balancing a ruler vertically on the palm of your hand while ...

In the past few months, a wave of tech corporations have announced significant staff cuts and attributed them to efficiency gains driven by artificial intelligence. Genuine disruption is visible in ...

Five years ago, scientists watched in wonder as synthetic bacteria grew and split into daughter cells. The bacteria’s extremely stripped-down genome still supported its entire life cycle. It was a ...

Booming energy demand is driving a scramble to set up new generating capacity, and one technology is proving to be the clear winner. Newly released federal data shows that solar power grew by more ...

Elon Musk has long said settling Mars is SpaceX’s raison d'être, but the world’s richest man has now pivoted his attention to the moon. The company is targeting an uncrewed lunar landing in March 2027 ...
