Duckweed is a tiny floating plant  that often becomes a hard-to-control weed in ponds and small lakes.

Yet these ecological lemons might become energy lemonade.

It's not all bad, duckweed has been used to clean contaminated water and to produce pharmaceuticals, and now the genome of Greater Duckweed (Spirodela polyrhiza) has given this miniscule plant's potential as a biofuel source a big boost. 

If China wants to save .009 of its population by 2050, they need to implement UN tobacco control policies, including surveillance and monitoring of tobacco use prevalence, creation of smoke-free environments, treatment of tobacco dependence, tobacco consumption taxation and other price controls, enforcement of heath warnings on tobacco packages and marketing bans.

Researchers have made a discovery regarding the behavior of a synthetic molecular oscillator, which could serve as a timekeeping device to control artificial cells.
