Researchers use magnetic fields for non-invasive blood glucose monitoring
Synex Medical, a Toronto-based biotech research firm backed by Sam Altman (the CEO of OpenAI), has developed a tool that can measure your blood glucose levels without a finger prick. It uses a combination of low-field magnets and low-frequency radio waves to directly measure blood sugar levels non-invasively when a…

What the evolution of our own brains can tell us about the future of AI
The explosive growth in artificial intelligence in recent years — crowned with the meteoric rise of generative AI chatbots like ChatGPT — has seen the technology take on many tasks that, formerly, only human minds could handle. But despite their increasingly capable linguistic computations, these machine learning systems remain surprisingly…

Mars’ core looks bigger than it is because it’s wrapped in radioactive magma
Data from a meteorite impact on Mars that was recorded by NASA’s InSight lander in 2021 is now helping to clear up some confusion about the red planet’s interior makeup. A pair of studies published today in the journal Nature separately determined that Mars’ iron-rich core is smaller and denser…

NASA’s John Mather keeps redefining our understanding of the cosmos
Space isn’t hard only on account of the rocket science. The task of taking a NASA mission from development and funding through construction and launch — all before we even use the thing for science — can span decades. Entire careers have been spent putting a single satellite into space.…

NASA’s Psyche spacecraft embarks on a six-year journey to its asteroid namesake
NASA’s Psyche spacecraft has blasted off and begun a six-year, 2.2-billion-mile journey to a peculiar asteroid. Astronomers have speculated that the space rock, also named Psyche, was once the partial core of a small planet in the early days of the Solar System. The seemingly iron- and nickel-rich asteroid may…

There’s no easy answer to being a space janitor
Earth’s orbit is getting crowded. Last year, a record 2,409 objects were sent to orbit, the bulk of which were satellites settling into the increasingly cluttered region 1,200 miles above our planet’s surface known as low Earth orbit. Another 2,000-plus satellites have joined them so far this year, according to…
