The testing of injecting RNA into Alzheimer's patients to reduce the levels of tau proteins is a possible new treatment for the more than 5.1 million people living with Alzheimer's. The treatment has shown some limitation in the testing done on chimps, more testing will be done on primates to discern the safety and efficacy on humans.

Apple joins with other tech giants in the Partnership on AI to Benefit People and Society to help steer the direction of artificial intelligence research. With the absence of regulations in the field, the group will work toward developing standards and ethics around the development and implementation of AI.

By applying 4.95 million atmospheres of pressure to liquid hydrogen, Harvard physicists have claimed they were able to make it metallic, a state of hydrogen that had never existed on Earth before. Physicists predict that metallic hydrogen is an authentic superconductor, so if stabilized, it could revolutionize everything from energy storage to rocketry.

Two more teams of researchers have found ways to create time crystals, lattices that repeat not in space but in time, breaking time-translation symmetry. Though applications are unclear, the research could help us better understand quantum properties and solve the problem of quantum memory associated with quantum computing.
