Scientists zero in on how lung cancer spreads Posted: 25 Dec 2014 11:35 AM PST Scientists have taken microscopic images revealing that the protein ties tethering cells together are severed in lung cancer cells.

Twelve new genetic causes of developmental disorders Posted: 25 Dec 2014 11:35 AM PST Scientists have discovered 12 new genetic causes of developmental disorders.They will ultimately analyze data from 12,000 families. The article describes results from the first 1133 samples, which have increased the proportion of patients that can be diagnosed by 10 per cent.

Egg and sperm race: Scientists create precursors to human egg and sperm Posted: 25 Dec 2014 11:35 AM PST Scientists have created primordial germ cells -- cells that will go on to become egg and sperm -- using human embryonic stem cells. Although this had already been done using rodent stem cells, this is the first time this has been achieved efficiently using human stem cells.

First scientific report shows police body-cameras can prevent unacceptable use-of-force Posted: 24 Dec 2014 07:31 AM PST As Obama pledges investment in body-worn-camera technology for police officers, researchers say cameras induce 'self-awareness' that can prevent unacceptable uses-of-force seen to have tragic consequences in the US over the past year -- from New York to Ferguson -- but warn that cameras have implications for prosecution and data storage.
