350.000 Jahre Klimageschichte archiviert in der Devils-Hole-Höhle, Nevada: Geologen der Universität Innsbruck untersuchen Niederschlagsmuster weit in die Vergangenheit zurück, um besser verstehen zu können, wie die Wüsten im Südwesten der USA künftig vom Klimawandel beeinflusst werden. (more…)
Die Felskluft Devils Hole in den USA ist weltweit einzigartig. Sie beherbergt ein Unterwasserreservoir, in dem seit hunderttausenden von Jahren konstante Bedingungen herrschen. In einem Projekt des Wissenschaftsfonds FWF untersuchen Forscherinnen und Forscher um Christoph Spötl dieses wertvolle Klimaarchiv und sind dabei einem Rätsel auf der Spur. (more…)
There is still quite a bit of interest in cloud services, and still no small demand for them. Due to this, there’s been a rush by all manner of service providers, both old and new, to provide cloud offerings to hungry customers. Indeed, of the roughly 20,000 North American service providers, just about 20 percent of these offer cloud services at this time, and this number is expected to grow sharply over the next few years. Yet at the same time, there will be a lot of attrition among these providers, if only because many of these organizations are only regional in nature, and offer only a small array of products — most of them just one or two.
At least that’s what Ashar Baig, a research director at Gigaom predicts. He provided his view on the near future and the recent past of cloud services at the recent ITEXPO in Las Vegas, Nevada. (more…)
High-Fiber Salad Bar May Help Lagomorphs Survive Climate Change
In some mountain ranges, Earth’s warming climate is driving rabbit relatives known as pikas to higher elevations or wiping them out. But University of Utah biologists discovered that roly-poly pikas living in rockslides near sea level in Oregon can survive hot weather by eating more moss than any other mammal.
“Our work shows pikas can eat unusual foods like moss to persist in strange environments,” says biology professor Denise Dearing, senior author of the new study, published online on Dec. 18, 2013 in the February 2014 issue of Journal of Mammalogy. “It suggests that they may be more resistant to climate change than we thought.” (more…)
SAN FRANCISCO — In the search for rogue nukes, researchers have discovered an unlikely tool: astronomical radio telescopes.
Ohio State University researchers previously demonstrated another unlikely tool, when they showed that South Korean GPS stations detected telltale atmospheric disturbances from North Korea’s 2009 nuclear test.
Both techniques were born out of the discovery that underground nuclear explosions leave their mark—on the outer reaches of Earth’s atmosphere. (more…)
A joint effort of citizen scientists and professional astronomers has led to the first reported case of a planet orbiting twin suns that in turn is orbited by a second distant pair of stars.
Aided by volunteers using the Planethunters.org website, a Yale-led international team of astronomers identified and confirmed discovery of the phenomenon, called a circumbinary planet in a four-star system.
Only six planets are known to orbit two stars, according to researchers, and none of these are orbited by distant stellar companions. (more…)
Thanks to the generosity of three professional meteorite hunters, the UA Lunar and Planetary Laboratory will own three samples of a rare kind of meteorite leftover from the earliest beginnings of the solar system.
To the untrained eye, the black, smooth-edged lump that is sitting under a glass cover looks similar to a piece of charcoal. But to scientists Dante Lauretta and Ed Beshore from the University of Arizona Lunar and Planetary Laboratory, it is one of the most intriguing stones they have ever seen.
“This meteorite is the oldest rock you’ll ever find on Earth. In fact, it formed 50 to 60 million years before the Earth even existed,” said Lauretta, who is a professor of planetary science and principal investigator of NASA’s OSIRIS-REx mission, which will send a spacecraft to return a sample from an asteroid in 2023.

Cloud services reduce time and money spent managing security and increase protection against cyberthreats, Microsoft study shows.
REDMOND, Wash. — Research released today by Microsoft Corp. shows that small and midsize businesses (SMBs) are gaining significant IT security benefits from using the cloud, according to a new Microsoft study in five geographies.
The study shows that 35 percent of U.S. companies surveyed have experienced noticeably higher levels of security since moving to the cloud.1 In addition, 32 percent say they spend less time worrying about the threat of cyberattacks. U.S. SMBs using the cloud also spend 32 percent less time each week managing security than companies not using the cloud. They are also five times more likely to have reduced what they spend on managing security as a percentage of overall IT budget. (more…)
