ByteDance is acquiring Chinese virtual reality headset maker Pico. Pico caters to both consumer and professional customers and it is known for its Neo lineup of standalone virtual reality headsets.

Luminate Medical has created a medical wearable that prevents hair loss resulting from chemotherapy. The device is a sort of mechanized compression garment for the head. It restricts blood flow to the skin of the scalp during chemo sessions, allowing the drugs to flow where they are needed while saving the hair follicles from damage. Animal tests have resulted in hair retention of around 80 percent with no adverse side effects. It will still take some time for full human trials to be set up, but initial tests show that it works exactly as expected on people as well. Luminate plans to sell its treatment for $1,500.
