‘Whisper’ laser tech sends audible messages to specific people

by Steve Dent, Engadget

It can beam tones, music and speech to someone’s ear from a distance.

Researchers from MIT have discovered a way to send highly targeted audio signals directly to someone’s ear at a distance using laser beams. The system works using the “photoacoustic” effect, where water vapor in the air absorbs light, forming sound waves. The research may pave the way to systems that allow audible messages to be transmitted to spies or other agents, warning them of impending danger like an active shooter.

Earth’s core may have hardened just in time to save its magnetic field

by Carolyn Gramling, ScienceNews

This shift both prevented the protective magnetic field from collapsing and recharged it.

Earth’s inner core solidified sometime after 565 million years ago — just in time to not only save the planet’s protective magnetic field from imminent collapse, but also to kick-start it into its current, powerful phase, a new study suggests.

AI is Fueling Smarter Prosthetics Than Ever Before

by Andrea Powell, Wired

THE DISTANCE BETWEEN prosthetic and real is shrinking. Thanks to advances in batteries, brain-controlled robotics, and AI, today’s mechanical limbs can do everything from twist and point to grab and lift. And this isn’t just good news for amputees. “For something like bomb disposal, why not use a robotic arm?” says Justin Sanchez, manager of Darpa’s Revolutionizing Prosthetics program. Well, that would certainly be handy.

Scientists bring new insight into how animals see

by University of Manchester, Phys.org

Scientists from The University of Manchester have found a way to trick the eye into thinking the world is brighter than it actually is.

Using a chemical compound, the team activated a small group of retinal neurons in dim light, which unexpectedly made almost the whole retina more active.

Missing-link in planet evolution found

by National Institutes of Natural Sciences, Phys.org

For the first time ever, astronomers have detected a 1.3 km radius body at the edge of the solar system. Kilometer-sized bodies like the one discovered have been predicted to exist for more than 70 years. These objects acted as an important step in the planet formation process between small initial amalgamations of dust and ice and the planets we see today.
