Yang et al., 2021) Scientists have been puzzling for decades over how the Australian bare-nosed wombat poops out neat little cubes of feces instead of tapered cylinders like pretty much all other animals. According to a new […]

What’s the technology behind a five-minute charge battery?
Enlarge (credit: StoreDot) Building a better battery requires dealing with problems in materials science, chemistry, and manufacturing. We do regular coverage of work going on in the former two categories, but we get a fair number of complaints about our inability to handle the third: figuring out how companies manage to take solutions to the […]
New metamaterial merges magnetic memory and physical changes
Enlarge For applications like robotics, there’s usually a clear division of labor between the processors that control the robot’s body and the actuators that actually control the physical changes of that body. But a new paper being released today blurs the lines between the two, using a magnetic switch in a way that both stores […]

(credit: ESO) AI and machine-learning techniques have become a major focus of everything from cloud computing services to cell phone manufacturers. Unfortunately, our existing processors are a bad match for the sort of algorithms that many of these […]
How electric lighting changed our sleep, and other stories in materials science

(credit: Chaloner Woods/Getty Images) There’s rarely time to write about every cool science-y story that comes our way. So this year, […]
New battery chemistry results in first rechargeable zinc-air battery
Enlarge (credit: Wikimedia Commons) Most of the disposable batteries you’ll come across are technically termed alkaline batteries. They work at high pH and typically use zinc as the charge carrier. Zinc is great because it’s very cheap, can be used to make one of the two electrodes, and, in the right context, allows the use […]
Coverage of “wooden satellites” misses the point

The plan is less insane than it sounds—wood […]
Atomically thin Cloth Create transistors that May reconfigure On-demand
Expand / / One club, just two behaviours. ) Right now, our chips are made on silicon. But basic limits on what could be accomplished with that substance contains investigators eyeing ways to utilize substances that have inherently smaller features, such as nanotubes or even atomically thin stuff. At least in concept, these can let […]
U.K. startup’s breakthrough Can Assist quantum computers from the Search for exotic Substances
A little U.K. startup has created an algorithm which greatly lowers the degree of calculating power required to run a metric which may pave the way for creation of new materials. Researchers from the business, Phasecraft, together with researchers in the University of Bristol, revealed {} issue from quantum physics– even just one that’s too […]
