Zika virus uses cells’ ‘self-care’ system to turn against host
A new study reveals the biological secret to the Zika virus's infectious success: Zika uses host cells' own 'self-care' system of clearing away useless molecules to suppress the host proteins that the virus has employed to get into those cells in the first place.
Home water-use app improves water conservation
A new study has found that a smartphone app that tracks household water use and alerts users to leaks or excessive consumption offers a promising tool for helping California water agencies meet state-mandated conservation goals. The study found that use of the app -- called Dropcountr -- reduced average household...
