A group of genes that play an essential role in building components of our cells can also impact human lifespan, finds a new study led by UCL researchers. The genes have previously been found to extend lifespan in small organisms, such as making fruit flies live 10% longer, but this is the first.
MIT physicists have discovered a new quantum bit, or “qubit,” in the form of vibrating pairs of atoms known as fermions. They found that when pairs of fermions are chilled and trapped in an optical lattice, the particles can exist simultaneously in two states—a weird quantum phenomenon known as superposition. In this case, the atoms held a superposition of two vibrational states, in which the pair wobbled against each other while also swinging in sync, at the same time.
