Planet hunters spy distant haul (BBC)
Astronomers eagerly await potential birth of ‘super’ sun
Astronomers have pinpointed two massive stars, orbiting close to each other in space, that could merge to create a “super” sun, 100 times bigger than our own. The massive “binary” star system, located in a galaxy orbiting the Milky Way, has been captured by NASA scientists using satellite and ground-based telescopes. (Independant)
New Earth-like planet ‘habitable’
Astronomers have found the first Earth-sized world circling its mother star at a distance suitable for life. It also has good prospects for liquid surface water — believed to be a key ingredient for life. (Discovery)
Scientists find most earth-like planet yet (Discovery)
Indian herbal remedy cancer hope
An Indian herbal remedy could one day be used to help fight pancreatic cancer, scientists hope. (BBC)
Brain creates new nerve cells
Researchers have discovered a type of brain cell that continuously regenerates in humans. (BBC)
Trials for bionic eye implants
A bionic eye implant that could help restore the sight of millions of blind people could be available to patients within two years. (BBC)
Chimps used stone hammers
Chimpanzees may have been using stone “hammers” as long as 4,300 years ago. (Discovery)
Turkana Boy skeleton stirs debate
Deep in the dusty, unlit corridors of Kenya’s national museum, locked away in a plain-looking cabinet, is one of mankind’s oldest relics: Turkana Boy, as he is known, the most complete skeleton of a prehistoric human ever found. (Discovery)
