Switches drive nearly every machine. A new one, made of folded DNA, does the same work at the scale of molecules. Scientists have long dreamed of developing nanoscale machines, but building reliable ...

Imagine if one company could become the railroad, electric utility, and cloud-computing provider of the emerging space economy. That potential fueled excitement around the long-anticipated initial ...

In May, evolutionary biologist Richard Dawkins wrote an op-ed suggesting AI chatbot Claude may be conscious. Dawkins did not express certainty that Claude is conscious. But he pointed out that ...

New drugs are taking on the slippery molecular switches that fuel deadly cancers—and AI is speeding up the hunt. For decades, a handful of molecular switches has haunted the nightmares of cancer ...

Huntington’s disease is tragically predictable. An inherited genetic mutation causes neurons to make distorted, sticky proteins. These proteins clump together and gradually overwhelm brain cells. The ...

There’s truth to the old adage, “Age is just a number.” People of the same age differ vastly in health and mental capabilities. One 80-year-old may be vibe coding with Claude, while another is ...

As demand for electric vehicles and grid storage surges, battery makers are searching for alternatives to lithium that are cheaper and easier to source. New research suggests sodium-ion batteries, ...

AI can rifle through enormous libraries of information to connect far-flung ideas—conceptual leaps remain a purely human skill. The planar unit distance problem, or Erdős problem 90, has intrigued ...

The unassuming vial of eye drops could easily belong on a pharmacy shelf. But swirling inside are microscopic bits of photosynthetic machinery made from plants. Within minutes of giving the drops to ...

As the AI boom accelerates, governments and utilities are struggling to keep pace with the industry's huge energy demands. New figures suggest data centers now consume about 6 percent of electricity ...

Uncovering nature’s secrets is no easy task. The daily life of a scientist is often grueling, frustrating, and—perhaps surprisingly—boring as they repeat experiments over and over. Here’s where AI ...

As AI demand for computing power surges, companies are searching for new ways to fuel data centers. One startup is now proposing floating data centers powered by ocean waves, and they just raised $140 ...
