"Frozen" copper behaves like precious metal in catalysis: study

Unique electron configuration of the 29th element Cu was excited by high energy plasma, resulting in the variation in its chemical property. Credit: SUN Jian and YU Jiafeng As a precious metal, copper more readily oxidizes to a positive valence (Cu + or Cu 2+) than the same family element Au or Ag. In general, this chemical property is mainly …

Watch a Tiny Gecko-like Robot Climb Upside Down

Roving Robot Rolls-Royce really wants to get into its jet engines. In July, the U.K. engineering firm unveiled the tiny, cockroach-like robot it designed to crawl into engines hard-to-reach areas. The goal: give mechanics a way to investigate issues without going through the complicated process of taking an engine separately. Now, a team from Harvard has produced another microbot for …

Bees can count on only four neurons in the brain

A hops choose between two patterns that contain different numbers of yellow circles. Credit: Lars Chittka Bees can solve obviously clear count data with very little nerve cells in their brains, according to researchers at Queen Mary University of London. To understand how bees are considered, the researchers simulated a very simple miniature "brain" on a computer with only four …

Right now is the peak time for Mille Lacs walleyes

However, during the first part of the ice season, his focus is entirely on Mille Lacs Lake Walleyes. "Early ice is my favorite part of the season," Roach said. "The fish can often be found in the same spots we found them in the fall, and they are usually aggressive." The aggressive feeding behavior does not remain throughout the winter, …

New equations go beyond Einstein's theory of general relativity

Artist view of loop quantum gravity effects in a black hole. The lower half of the picture shows the black hole which, according to general relativity, sheds everything including light. Loop quantum gravity, a theory that expands Einstein's general relativity using quantum mechanics, overcomes this enormous trait and frees everything displayed in the upper half of the image, which solves …
