Building a computer that can support artificial intelligence at the scale and complexity of the human brain will be a colossal engineering effort. Now researchers at the National Institute of Standards and Technology have outlined how they think we'll get there.

Summary: Protein hyper-interleukin-6, a "designer protein" that has to be produced via genetic engineering, enabled a paralyzed mouse to walk again. Spinal cord injuries caused by sports or traffic accidents often result in permanent disabilities such as paraplegia.

Stanford researchers made a groundbreaking discovery about brain tumors. The study reports high-grade gliomas form synapses which hijack electrical signals from healthy neurons in the brain, promoting tumor growth. Interrupting the signals with a drug currently used to treat epilepsy reduces the tumor growth in mouse models.
