Polly Want a Chainsaw? Lyrebird Imitates Jackhammer, Drill, Other Tools
By Matthew Hall - AOL NewsBird keepers at the Adelaide Zoo in Australia are eagerly awaiting breeding season to hear what new calls the zoo's resident lyrebird has learned. Known as Chook, the zoo's lyrebird is an expert mimic and has previously heard and copied construction sounds, including hammers, drills, two-way radios and chainsaws, as well as traffic noises and the clicks of tourist cameras. In an amazing video, Chook is seen expertly mimicking the kookaburra, an Australian bird known for its laughing call, adding to a repertoire that he hopes will attract a mate. "Chook is going well and is just starting ...
Did Chinese Scientists Turn Mice Gay?
By Steven Hoffer - AOL NewsIf your pet mouse doesn't find the lady mice attractive, he could be lacking in serotonin. New research from scientists in China argues that the so-called happiness hormone plays a role in the sexual orientation of mice, the BBC reports. The study, published in the current edition of Nature, finds that male mice bred with brains unreceptive to serotonin lost their preference for female mice. The same was true for mice bred without the tryptophan hydroxylase 2 gene, which is necessary to produce serotonin. "This is the first time, to our knowledge, that a neurotransmitter in the brain has ...

Scientists Say Planet May Have Mountains of Diamonds
By Hugh Collins - AOL News
(Dec. 9) -- If Earth is the Blue Planet, call this the Bling Planet. Astronomers say they have spotted a planet that could contain mountains of diamonds. WASP-12b, a gas giant about 871 light-years from Earth, seems to have an unusually large amount of carbon in its atmosphere. Diamonds form when carbon is compressed at extremely high temperatures. JPL-Caltech / NASA This illustration shows the searing-hot gas planet WASP-12b (orange orb) and its star. NASA's Spitzer Space Telescope discovered that the planet has more carbon than oxygen, making it the first carbon-rich planet ever ...
Scientists Find Fountain of Youth ... in Mice
By Deborah Hastings - AOL News
(Nov. 29) -- Scientists have been able to reverse the aging process in mice, a stunning feat that may help regenerate organs in elderly humans, according to a new study published online in the journal Nature. The experimental treatment developed by researchers at Harvard Medical School turned weak and feeble old mice into healthy rodents by regenerating their aged bodies. OJO Images When scientists increased levels of the enzyme telomerase in the mice, their organs began to rejuvenate, according to a new study. "These mice were equivalent to 80-year-old humans and were about to pass ...
Dream Recording (and Playback) Comes Closer to Reality
By Katie Drummond - AOL News(Oct. 28) -- Dream journals are so last century. A sophisticated brain-machine interface might one day give us the chance to record -- and then revisit, rewind and presumably overanalyze -- our nocturnal imaginings. In a remarkable experiment on a group of epileptics, whose brains had been wired to computers, researchers at the California Institute of Technology used celebrity images to explore patterns and dynamics of focus within the mind. First, the team established links between the activity of specific neurons and pictures of different celebrities. For example, one neuron might fire in ...

Breakthrough Study Finds Genetic Keys to High Cholesterol
By Katie Drummond - AOL News(Aug. 4) -- Scientists say they've found a group of genes that help explains why high cholesterol (and high triglycerides) can run in the family. Researchers from 17 countries, funded primarily by the National Institutes of Health, came up with 95 genetic variants (59 of them previously unknown) that explain the hereditary component of those key heart disease risk factors after scanning the genomes of 100,000 people. The team's research is published in this week's issue of Nature. "The new findings point us to specific genetic signposts that allow us to understand more fully why many ...
Squirrels Are Getting Fatter Now, Too (Thanks to Global Warming!)
By Carl Franzen - AOL News(July 21) -- Some squirrels are getting a lot plumper than they used to be, but the root cause of their weight gain isn't what you might suspect (not saturated-fatty nuts, sorry!): It's global warming. That's the conclusion drawn in a three-decade-long study on the yellow-bellied marmots -- large ground squirrels also known as rock chucks -- that inhabit the Upper East River Valley in Colorado, the results of which are in the latest issue of the journal Nature. It's reportedly the first time that climate change has been linked to physical changes in an animal population. A yellow-bellied ...
Find Reveals Early Humans Who Endured Harsh Cold
By Traci Watson - AOL NewsLONDON (July 7) -- Scientists have depicted early humans as wimps who couldn't hack it in chilly northern climates, but a newly discovered cache of stone tools is forcing archaeologists to revise their opinions. Scientists reported at a news conference here today that creatures much like us managed to carve out a living at a spot on the coast of England roughly 900,000 years ago, when the area would have resembled today's southern Scandinavia in climate and landscape. Never before have early humans been shown to live so far north. The finding, which will be published in Thursday's edition of ...
