The Linac Coherent Light Source (LCLS) at the SLAC National Accelerator Laboratory is using X-rays to measure, in atomic detail, a key process at work in extreme plasmas like those found in stars, the rims of black holes and other massive cosmic phenomena.

Wilms' tumors, a type of cancer typically found in the kidneys of young children, might have a new weapon against them. A new therapeutic approach that one day might be used to treat some of the more aggressive types of this disease could be possible now that  scientists have isolated cancer stem cells that lead to the growth of the tumors.

The Hubble Space Telescope has detected seven primitive galaxies formed more than 13 billion years ago, and also a candidate, at redshift 11.9, for the record for the most distant galaxy found to date. 

The images offer the deepest ever view of the Universe at near-infrared wavelengths, which capture the redshifted light of early galaxies. Because light takes so long to travel from these remote objects, astronomers are looking back in time and seeing those galaxies as they appeared just 600 million years after the Big Bang.

Do you prefer to have a few close friends or a larger social circle that is less deep? Social psychologists say your preference reflect your personality but also individual circumstances - like socioeconomic conditions.

The slow loris (Nycticebus) is a primate genus closely related to the lemur and found across South East Asia, from Bangladesh and China's Yunnan province to the island of Borneo.

The slow loris is rare amongst primates for having a toxic bite, and is rated as Vulnerable or Endangered on the IUCN Red List. Maybe not so endangered, since researchers have found a brand new species.  A team's analysis of the primate's distinctive facial fur markings, published in the American Journal of Primatology, reveals the existence of one entirely new species, while two possible sub-species are being officially recognized as unique. 

A miniature extraterrestrial version of Africa's Nile River Valley has been spotted on Saturn’s moon Titan - it stretches more than 400 km from its "headwaters" to a large sea.  

Have you ever before seen such a large river system in high resolution outside Earth?  No, you have not. 

Scientists deduce that the river is filled with liquid because it appears dark along its entire extent in the high-resolution radar image, indicating a smooth surface.   Titan is the only other world we know of that has stable liquid on its surface. While Earth’s hydrologic cycle relies on water, Titan’s equivalent cycle involves hydrocarbons such as ethane and methane.
