Climate change impacts will require major but very uncertain transformations of global agriculture systems by mid-century, according to new research from the International Institute for Applied Systems Analysis. —> Read More Here
Most power stations rely on boilers to convert water into steam, but the phase transition involved is highly complex. During the phase transition, no one is exactly sure what’s occurring inside the boiler — especially how bubbles form. So a team of researchers in Japan set out to find an answer and in the Journal of Chemical Physics, they describe how they were able to simulate bubble nucleation from the molecular level. —> Read More Here
The United States is a melting pot of different racial and ethnic groups, but it has not been clear how the genetic ancestry of these populations varies across different geographic regions. In a landmark study published by Dec. 18 in the American Journal of Human Genetics, researchers analyzed the genomes of more than 160,000 African-Americans, Latinos, and European-Americans, providing novel insights into the subtle differences in genetic ancestry across the United States. —> Read More Here
Computer scientists from the University of Wyoming and Cornell University in New York were able to hack the way a computer views objects using unique images that appear as static to humans. —> Read More Here
High-energy jets powered by supermassive black holes can blast away a galaxy’s star-forming fuel, resulting in so-called “red and dead” galaxies: those brimming with ancient red stars yet containing little or no hydrogen gas to create new ones.
The team responsible for the Sample Analysis at Mars (SAM) instrument suite on NASA’s Curiosity rover has made the first definitive detection of organic molecules at Mars.
WASHINGTON (Reuters) – You might want to be careful about who you call a birdbrain. Some of our feathered friends exhibit powers of perception that put humans to shame.
Dinner plate-sized ice (pictured) was seen forming on a quiet stretch of the River Dee, close to Aboyne in Aberdeenshire following heavy frosts that are thought to have frozen foam on the river. —> Read More Here
A Colorado man can now control two prosthetic arms with his mind.
Les Baugh lost both his arms in an electrical accident 40 years ago. But with the help Johns Hopkins University’s Applied Physics Laboratory and DARPA (Defense Advanced Research Projects Agency), he’s able to control a set of Modular Prosthetic Limbs with his nerves. All he has to do is think about moving his arms, and they move.
Nothing is permanently attached to him; Baugh wears what is called a “socket,” which connects the prosthetics to his body. The researchers measured the way his muscles and nerves react when Baugh thinks about moving his arms. Then, when he thinks about moving his arms and hands in a certain way, the prosthetics move.
Baugh is the first bilateral shoulder-level amputee to wear two Modular Prosthetic Limbs at once, according to the researchers. He’s spending a lot of time practicing different tasks.
“Maybe I’ll be able to — for once — be able to put change in a pop machine and get the pop out of it,” Baugh said in a video about the breakthrough. “Simple things like that that most people never think of.” He can only —> Read More Here
Scientists in Massachusetts and Texas have revealed a spectacular light show taking place in two colliding galaxies (shown), NGC 2207 and IC 2163, 130m light-years away. —> Read More Here
