In any event in the case of Phobos with a mean radius of 11.1 we have an indicated shell thickness that is 2.5 to 3 km leaving a potential void having a radius of plausibly 8 km. This is huge of course but a spinning space habitat naturally provid
An international team including geodynamic modelers from the GFZ German Research Centre for Geosciences together with geochemists from the J. Fourier University of Grenoble, the Max Plank Institute in Mainz, and Vernadsky-, Schmidt- and Sobolev-Insti
SDO was able to make the discovery because of its unique ability to monitor the sun’s extreme UV output in high resolution nearly 24 hours a day, 7 days a week. With that kind of scrutiny, it’s tough to keep a secret--even one as old as this.
Varied impact craters, valleys, canyons and mountains among the highest in the Solar System - the 3D images and videos of the asteroid Vesta created byscientists at the German Aerospace Center (Deutsches Zentrum fur Luft- und Raumfahrt; DLR) reveal a
Dr. Denise L. Herzing intends to do something no person has ever done in the long history of the human race: establish a real dialogue with another species. Her goal is simple achieve a two-way conversation with dolphins, perhaps the smartest mammals
Developed in 2008 by the University of Washington, it is a fun-for-purpose video game in which gamers, divided into competing groups, compete to unfold chains of amino acids -- the building blocks of proteins -- using a set of online tools.
R returned evidence of living microorganisms. Initially discounted by NASA and most space scientists, the results of this milestone project have, nonetheless, been causing excitement and controversy ever since. In 1997, after 21 years of study of the
A cache of feathers preserved in amber, dating from around 70 to 85 million years ago, was just found in Canada, showing that border between winged dinosaurs and the earliest avians.
The National Maritime Museum's Royal Observatory in Greenwich England has announced the 2011 winners of its Astronomy Photographer of the Year contest, across categories from “Our Solar System” and “Deep Space” to “Best Newcomer” and “Young Astronomy
From there, the story echoes that of countless islands where the introduction of rats, cats, weasels and other predators upends the ecosystem. The island's nesting seabirds had no defenses against the predatory rats, which ate their eggs and their y
"The geological record offers a longer perspective on rates of change," Thompson said, "and sea-level changes during previous warm intervals are especially relevant to today's situation." Sea levels during the Last Interglacial are known to ha
One would expect, then, that the tidal cycle would be the clock that drives their gene expression. But in fact, as Gracey's tests discovered, while a "tidal clock" probably does exist for mussels, the lion's share of their gene expression is inst
Researchers led by University of Alberta paleontologist Ryan McKellar say these specimens represent distinct stages of feather evolution, from early-stage, single filament protofeathers to much more complex structures associated with modern diving bi
As glass office and condominium towers have proliferated in the last decade, so, too, have calls to make them less deadly to birds. The San Francisco Planning Commission adopted bird-safety standards for new buildings in July, and this month that cit
Mystery of the century, you guys. No, the millenium. All times. A new paper in the journal Brain, Behavior and Evolution has a new answer to the eternal question: why do our fingers and toes get all wrinkly after bathtime?
A solid-state supercapacitor based on nanotubes created by researchers at Rice University could be useful for both large and small scale energy storage.
Twinkling stars may look like diamonds in the sky, but iron meteorites seeded the world with gold. That's the fascinating conclusion that a new study, "The tungsten isotopic composition of the Earth’s mantle before the terminal bombardment," publi
Scientists are only now figuring this out, "because it certainly sounds like a whistle," said study researcher Peter Madsen of the Institute of Bioscience at Aarhus University in Denmark, adding that the term was coined in a paper published in 1949
After baffling biologists for decades, the female orgasm has resisted yet another attempt to explain its elusive evolutionary origins.
Ford and a colleague collected samples, which were later analyzed at DFO's Pacific Biological Station in Nanaimo, British Columbia. The tests confirmed Ford's long-held hypothesis: the offshore orcas weren't eating salmon or sea lions. They wer
He thinks hard scientific evidence, in the form of DNA, could be provided by researchers in the United States later this year, or next. But then again, his hopes have been raised before – only to be dashed when material promised by Sasquatch hunters
"When the number of committed opinion holders is below 10 percent, there is no visible progress in the spread of ideas. It would literally take the amount of time comparable to the age of the universe for this size group to reach the majority," s
All living creatures on this planet use the same 20 amino acids, even though there are hundreds available in nature. Scientists therefore have wondered if life could have arisen based on a different set of amino acids. And what's more, could life ex
But for the first time, scientists have achieved a quantum measurement with virtually no additional disturbance beyond what quantum mechanics deems unavoidable.
Planetary scientists thought they knew what to expect when NASA's Dawn spacecraft returned the first close-up portrait of the giant asteroid Vesta last month. Fuzzy images from the Hubble Space Telescope (HST) taken in 1996 seemed to show that somet
Stanford physicists probing the sun's deep interior have predicted the emergence of sunspots on the surface a full two days before they appear, providing the first early warning of the violent solar storms that can endanger astronauts in space, di
Astronomers just spotted a brand-new supernova mere hours after it exploded, thanks to a robotic telescope and some smart computer algorithms.
For the first time, a black hole has been caught in the act of tearing apart and swallowing a star that got too close.
Mankind may be facing a devastating mass extinction in the near future warn a group of science experts. Five mass extinctions that occurred during the past half billion years followed biological and chemical disruptions to the oceans—the same kind of
Two years ago when researchers began to piece the bones together they quickly realised that they were in fact dealing with two separate animals; an adult plesiosaur and a smaller juvenile. The study's authors report that the juvenile was unlike
