Sitting on the outskirts of our galaxy’s gravitational pull, Tucana II … Read more
[ad_1] Scientists are finding out how to make materials that break and reset, relying only on the flow of energy from their surroundings. This research could allow future military robots to get rid of their own energy. Credit: Yongjin Kim, UMass Amherst Army-funded researchers have discovered how to make materials capable of self-propelling, allowing materials … Read more

[ad_1] Frozen Greenland is set to become much less frozen before the end of the 21st century. By 2055, winter snowfall on the Greenland ice sheet will no longer be enough to replenish the ice that Greenland loses every summer, new research shows. Rising global temperatures are behind this dramatic change. If the Earth continues … Read more

[ad_1] Credit: CC0 Public Domain When two sheets of graphene are stacked on top of each other at the right angle, the layered structure turns into an unconventional superconductor, allowing electric currents to flow without resistance or wasted energy. This “magic angle” transformation in bilayer graphene was first observed in 2018 in the group of … Read more
