Computer rendering: Graduate student brings extinct plants 'back to life'

Posted: 11 Apr 2014 12:38 PM PDT

Most fossilized plants are fragments indistinguishable from a stick, but a graduate student hopes a new technique will allow paleontologists to more precisely identify these fossils. A graduate student showed the power of this technique by turning a 375 million-year-old lycopod fossil into a life-like rendering.

Odds that global warming is due to natural factors: Slim to none

An analysis of temperature data since 1500 all but rules out the possibility that global warming in the industrial era is just a natural fluctuation in the earth's climate, according to a new study.

New form of matter: Exotic hadron with two quarks, two anti-quarks confirmed

Posted: 11 Apr 2014 06:19 AM PDT

Physicists have confirmed the existence of exotic hadrons -- a type of matter that cannot be classified within the traditional quark model. "We've confirmed the unambiguous observation of a very exotic state -- something that looks like a particle composed of two quarks and two anti-quarks," said one of the scientists. "The discovery certainly doesn't fit the traditional quark model. It may give us a new way of looking at strong-interaction physics."

Appearance of night-shining clouds has increased

First spotted in 1885, silvery blue clouds sometimes hover in the night sky near the poles, appearing to give off their own glowing light. Known as noctilucent clouds, this phenomenon began to be sighted at lower and lower latitudes -- between the 40th and 50th parallel -- during the 20th century, causing scientists to wonder if the region these clouds inhabit had indeed changed -- information that would tie in with understanding the weather and climate of all Earth.

Love is a many-faceted thing: Regular churchgoers and married people most satisfied with their love life

Posted: 09 Apr 2014 07:30 AM PDT

Scientists found that a combination of factors such as age, religious involvement, marital status and love style (e.g. manipulative or playful), influence a person's love satisfaction. While education does not impact a person's love life satisfaction, religious involvement does.

Ready for your close-up? Distance at which facial photos are taken influences perception, study shows

Posted: 26 Sep 2012 12:30 PM PDT

As the saying goes, "A picture is worth a thousand words." Previous studies have examined how our social judgments of pictures of people are influenced by factors such as whether the person is smiling or frowning, but until now one factor has never been investigated: the distance between the photographer and the subject. According to a new study, this turns out to make a difference.
