Yosemite's Alpine Chipmunks Threatened By Climate Change
2012-02-20 04:48:40

Global warming has forced alpine chipmunks in Yosemite to higher ground, prompting a startling decline in the species' genetic diversity, according to a new study by researchers at the University of California, Berkeley. The study, appearing Sunday, Feb. 19, in the advance online publication of the journal Nature Climate Change, is one of the first to show a hit to the genetic diversity of a species because of a recent climate-induced change in the animals' geographic range. What's more,...

Pssst, Did You Hear That Gossiping Is Good For Your Health?
2012-01-19 09:20:23

Researchers at UC Berkeley have determined that water cooler chatter and idle office tattling can have stress-relieving benefits, provided it is the correct sort of gossip that is helpful to others and not demeaning. A study using four experimental settings led to constructive outcomes using “pro-social” gossip to describe people warning about deceitful behavior observed in others. This is different from the type of hushed chatter we do when we discuss the bad behavior of...

August Supernova Was A White Dwarf

Fluke observation 4 hours after star exploded allows stronger limits on size of progenitor Last year's discovery of the nearest Type Ia supernova in decades — captured only 11 hours after it exploded — allowed astronomers to finally cinch the identity of the stars behind these explosions, which have become key measures of cosmic distance. That supernova, called SN2011fe, and presumably most Type Ia supernovae were originally white dwarfs extremely dense and compact stars...

[ Watch the Video ] Robots, like lizards, need a tail to remain upright when they stumble during leap University of California, Berkeley, biologists and engineers including undergraduate and graduate students studied how lizards manage to leap successfully even when they slip and stumble, and found that swinging the tail upward is the key to preventing a forward pitch that could send them head-over-heels into a tree. The scientists subsequently added a tail to a robotic car they...

Emotional differences between the rich and poor, as depicted in such Charles Dickens classics as “A Christmas Carol” and “A Tale of Two Cities,” may have a scientific basis. Researchers at the University of California, Berkeley, have found that people in the lower socio-economic classes are more physiologically attuned to suffering, and quicker to express compassion than their more affluent counterparts. By comparison, the UC Berkeley study found that individuals in...

Image 1 - Monster Galaxies Found To Harbor Record Massive Black Holes
2011-12-06 10:40:02

Astronomers from UC Berkeley have discovered the largest black holes to date -- two monstrous abyssal voids with masses equivalent to more than 10 billion suns, threatening to consume everything in its path within a region five times the size of our own solar system. The massive black holes are at the centers of two galaxies more than 300 million light years away. Such holes could be the gravitational foundations of galaxies and clues to the fates of violent quasars, the powerful...

Dreaming Helps Take The Sting Out Of Painful Memories

UC Berkeley researchers have found that stress chemicals shut down and the brain processes emotional experiences during the REM dream phase of sleep They say time heals all wounds, and new research from the University of California, Berkeley, indicates that time spent in dream sleep can help. UC Berkeley researchers have found that during the dream phase of sleep, also known as REM sleep, our stress chemistry shuts down and the brain processes emotional experiences and takes the painful...

Low-temperature discharges generate oxygen, nitrogen radicals that kill microbes for week University of California, Berkeley, scientists have shown that ionized plasmas like those in neon lights and plasma TVs not only can sterilize water, but make it antimicrobial — able to kill bacteria — for as long as a week after treatment. Devices able to produce such plasmas are cheap, which means they could be life-savers in developing countries, disaster areas or on the battlefield...

There´s definitely something to be said for first impressions. New research from the University of California, Berkeley, suggests it can take just 20 seconds to detect whether a stranger is genetically inclined to being trustworthy, kind or compassionate. The findings reinforce that healthy humans are wired to recognize strangers who may help them out in a tough situation. They also pave the way for genetic therapies for people who are not innately sympathetic, researchers said....

Einsteinium is a metallic synthetic element with the symbol Es and atomic number 99. It became the seventh transuranic (atomic number higher than 99) element produced. It was named for Albert Einstein. It is an element found within the actinoid series which includes Actinium. Though it has only been produced in small amounts, it has been accurately determined to be silver in coloration. Like all synthetic elements, einsteinium isotopes are highly radioactive and are extremely toxic. Besides...
