Babies remember nothing but a good time, study says

Posted: 24 Nov 2014 11:36 AM PST

Researchers performed memory tests with 5-month-old babies, and found that the babies better remembered shapes that were introduced with happy voices and faces. Past studies have shown that babies are very tuned to emotions, including the emotions of animals.

Asteroid impacts on Earth make structurally bizarre diamonds

Scientists have settled a longstanding controversy over a purported rare form of diamond called lonsdaleite -- a type of diamond formed by impact shock, but which lacks the three-dimensional regularity of ordinary diamond.

Global warming skeptics unmoved by extreme weather

Posted: 24 Nov 2014 09:54 AM PST

What will it take to convince skeptics of global warming that the phenomenon is real? Surely, many scientists believe, enough droughts, floods and heat waves will begin to change minds. But a new study throws cold water on that theory.

Enabling biocircuits: New device could make large biological circuits practical

Posted: 24 Nov 2014 09:53 AM PST

Researchers have made great progress in recent years in the design and creation of biological circuits -- systems that, like electronic circuits, can take a number of different inputs and deliver a particular kind of output. But while individual components of such biological circuits can have precise and predictable responses, those outcomes become less predictable as more such elements are combined. Scientists have now come up with a way of greatly reducing that unpredictability, introducing a device that could ultimately allow such circuits to behave nearly as predictably as their electronic counterparts.

Declining loneliness among American teenagers

In an effort to study the societal trend of loneliness, researchers conducted an analysis of data on high school and college students in the United States, and come up with some encouraging results.

Mental disorders due to permanent stress?

Posted: 21 Nov 2014 05:29 AM PST

Activated through permanent stress, immune cells will have a damaging effect on and cause changes to the brain. This may result in mental disorders. Medical researchers are studying the effects of permanent stress on the immune system.

Little Ice Age was global: Implications for current global warming

Posted: 19 Nov 2014 05:45 PM PST

Researchers have shed new light on the climate of the Little Ice Age, and rekindled debate over the role of the sun in climate change. The new study, which involved detailed scientific examination of a peat bog in southern South America, indicates that the most extreme climate episodes of the Little Ice Age were felt not just in Europe and North America, which is well known, but apparently globally. The research has implications for current concerns over global warming.
