Credit: Zhengyu Ju and Guihua Yu The conductive carbon charges in lithium-ion batteries enable high power with reversible energy storage. Lithium-ion batteries are the main rechargeable energy source for many portable devices and electric vehicles, but their …

[ad_1] when two neutron stars collide, the universe leaps. The extreme crash is explosive and creates a “kilonova”, which emits a bright and rapid flash of gamma rays. It also sends ripples through the fabric of space-time. So, scientists believe, the cosmic crash will likely create a newly melted object …

[ad_1] MADISON, Wis. Researchers have discovered a previously unknown way in which pancreatic cells decide how much insulin they secrete. It could provide a promising new target for drug development to increase insulin production in people with type 2 diabetes. In a couple of articles recently published in Cell metabolism, …
