The ants that conquered the world
OIST professor Evan Economo sequenced more than three hundred ant species to unravel the evolution of one globally dominant ant genus.

Optogenetics captures neuronal transmission in live mammalian brain
EPFL scientists have used a cutting-edge method to stimulate neurons with light.

Egg and sperm race: Scientists create precursors to human egg and sperm
Scientists at the University of Cambridge working with the Weizmann Institute have created primordial germ cells -- cells that will go on to become egg and sperm -- using human embryonic stem cells.

NASA looks at some severe holiday weather from space
Severe weather in the form of tornadoes is not something people expect on Christmas week but a storm system on Dec.

Scientists zero in on how lung cancer spreads
Cancer Research UK scientists have taken microscopic images revealing that the protein ties tethering cells together are severed in lung cancer cells.

First scientific report shows police body-cameras can prevent unacceptable use-of-force
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.

Locking mechanism found for 'scissors' that cut DNA
Researchers at Johns Hopkins have discovered what keeps an enzyme from becoming overzealous in its clipping of DNA.

Project pinpoints 12 new genetic causes of developmental disorders
Deciphering Developmental Disorders, the world's largest, nationwide and genome-wide diagnostic sequencing program, has discovered 12 new genetic causes of developmental disorders.

Human primordial cells created in the lab
A cell programming technique developed at the Weizmann Institute turns them into the earliest precursors of sperm and ova.

Scientists identify rare cancer's genetic pathway
An international research team, including four Simon Fraser University scientists, has identified the 'mutational landscape' of intrahepatic cholangiocarcinoma, a rare, highly fatal form of liver cancer that disproportionately affects people in Asian countries.

NASA-NOAA's Suomi NPP satellite spots birth of Tropical Cyclone Kate
The tropical low pressure area previously known as System 95S organized and strengthened into Tropical Cyclone Kate on Dec.
