Cambridge researchers have created a groundbreaking $10 optical sensor that delivers the precision of laboratory equipment in a device small enough for wearable technology. It identified foods, plastics, and medicines with 100% accuracy in tests and demonstrated the ability to monitor blood glucose, alcohol, and other health markers without invasive procedures.

Researchers analyzing nearly 150,000 Reddit posts uncovered unexpected symptom reports linked by users to unapproved versions of retatrutide, including increased appetite, sleep disturbances, and elevated heart rates. The findings differ from clinical trial results and highlight how AI could help identify potential drug safety signals that warrant further investigation.

Scientists have achieved a quantum breakthrough by creating an ultra-clean surface where individual molecules can maintain their delicate quantum properties at the fundamental limit. The discovery could unlock unprecedented control over molecules and help drive the next generation of quantum technologies.

Scientists discovered that atomic steps just one atom high can guide quantum vortices through superconductors, making them move more than 1,000 times more easily in one direction than another. This remarkable control over quantum motion could lead to a new generation of ultra-efficient superconducting electronics.

A new study reveals that people draw a surprisingly sharp line between human consciousness and artificial intelligence, even when both behave identically. Researchers found that participants considered even the most responsive AI less conscious than the least responsive human. Yet when asked about "awareness" instead, people judged humans and AI much more similarly.
