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.

Today it is common to refer to sugar and high-fructose corn syrup as "sugary ingredients." Sugar produced from sugar cane or sugar beets is called sucrose, which is a chemical compound in which glucose and fructose -- two different six-carbon, so-called simple sugars -- are chemically bound together.

In January of 2012, a new X-ray source flared and rapidly brightened in the Andromeda galaxy (M31), l2.5 million light-years from earth. The event was classified as an ultraluminous X-ray source (ULX), the second ever seen in M31 and efforts with X-ray telescopes and radio observatories resulted in the first detection of radio-emitting jets from a stellar-mass black hole outside our own galaxy.

A ULX is thought to be a binary system containing a black hole that is rapidly accreting gas from its stellar companion. To account for the high-energy output, gas must be flowing into the black hole at a rate very near a theoretical maximum - which astronomers do not yet fully understand.

Retinoblastoma tumor suppressor proteins is, shall we say, untraditional.  But it could mean new ways to treat cancer.

As an organism grows, proteins essential for fueling its prosperity typically toe a tight line, performing their jobs at the right place and time. If these proteins go rogue, disasters such as cancer can result.
