Researchers have invented a smartphone-controlled soft brain implant that can be recharged wirelessly from outside the body — ScienceDaily

A group of KAIST researchers and collaborators have engineered a tiny brain implant that can be wirelessly recharged from outside the body to control brain circuits for long periods of time without battery replacement. The device is constructed of ultra-soft and bio-compliant polymers to help provide long-term compatibility with tissue. Geared with micrometer-sized LEDs (equivalent […]

A single gene ‘invented’ haemoglobin several times — ScienceDaily

Thanks to the marine worm Platynereis dumerilii, an animal whose genes have evolved very slowly, scientists from CNRS, Université de Paris and Sorbonne Université, in association with others at the University of Saint Petersburg and the University of Rio de Janeiro, have shown that while haemoglobin appeared independently in several species, it actually descends from […]

Who invented the Electoral College?

The delegates in Philadelphia agreed, in the summer of 1787, that the new country they were creating would not have a king but rather an elected executive. But they did not agree on how to choose that president. Pennsylvania delegate James Wilson called the problem of picking a president “in truth, one of the most […]

Homo erectus, not humans, may have invented the barbed bone point

A type of bone tool generally thought to have been invented by Stone Age humans got its start among hominids that lived hundreds of thousands of years before Homo sapiens evolved, a new study concludes. A set of 52 previously excavated but little-studied animal bones from East Africa’s Olduvai Gorge includes the world’s oldest known […]
