How long the battery of your phone or computer lasts depends on how many lithium ions can be stored in the battery’s negative electrode material. If the battery runs out of these ions, it can’t generate an electrical current to run a device and ultimately fails.
It may still be decades before quantum computers are ready to solve problems that today’s classical computers aren’t fast or efficient enough to solve, but the emerging “probabilistic computer” could bridge the gap between classical and quantum computing.
A new cancer is diagnosed every 30 seconds in the United States. Every three minutes, two people in the U.S. die from cancer. Some of the deaths related to the disease arise from the fact that the same drug that helps one person can be detrimental to another with the same type of cancer.
The metallic asteroid Psyche has mystified scientists because it is less dense than it should be, given its iron-nickel composition. Now, a new theory could explain Psyche’s low density and metallic surface.
Medications that mitigate inflammation caused by a variety of diseases including rheumatic arthritis may also compromise a person’s immune system, but a new approach points to a possible solution to this problem.
Soldiers, athletes could have improved outcomes from traumatic brain injury through faster diagnosis using urine analysis
A traumatic brain injury is often easily suspected and can be confirmed and treated if necessary following an injury using a blood analysis, but scientists are reporting that even one mild blast to the brain can cause very subtle but permanent damage as well. Urine analysis taken within one week of a mild to traumatic brain injury also can provide faster diagnosis and treatment for such injuries.
