It's a gas: dinosaur flatulence may have warmed Earth
Mon,7 May 2012 11:40 AM PDT
Reuters -  WASHINGTON (Reuters) - In a major new climate finding, researchers have calculated that dinosaur flatulence could have put enough methane into the atmosphere to warm the planet during the hot, wet Mesozoic era. Like gigantic, long-necked, prehistoric cows, sauropod dinosaurs roamed widely around the Earth 150 million years ago, scientists reported in the journal Current Biology on Monday. And just like big cows, their plant digestion was aided by methane-producing microbes. ...

Scientists "switch off" brain cell death in mice
Sun,6 May 2012 10:01 AM PDT
Reuters -  LONDON (Reuters) - Scientists have figured out how to stop brain cell death in mice with brain disease and say their discovery deepens understanding of the mechanisms of human neurodegenerative diseases such as Alzheimer's and Parkinson's. British researchers writing in the journal Nature said they had found a major pathway leading to brain cell death in mice with prion disease, the mouse equivalent of Creutzfeld-Jacob Disease (CJD). They then worked out how to block it, and were able to prevent brain cells from dying, helping the mice live longer. ...

"Super Moon" to light up night sky this weekend
Sat,5 May 2012 12:51 PM PDT
Reuters -  WASHINGTON (Reuters) - A "super Moon" will light up Saturday's night sky in a once-a-year cosmic show, overshadowing a meteor shower from remnants of Halley's Comet, the U.S. space agency NASA said. The Moon will seem especially big and bright since it will reach its closest spot to Earth at the same time it is in its full phase, NASA said. The Moon "is a 'super Moon,' as much as 14 percent bigger and 30 percent brighter than other full Moons of 2012," it said in a statement. The scientific term for the phenomenon is "perigee moon. ...

"Made in space" coming soon to a product near you
Fri,4 May 2012 06:38 AM PDT
Reuters - BERLIN (Reuters) - The European Space Agency is hatching plans for a branding campaign aimed at making people more aware of the benefits of spending their hard-earned taxes on the International Space Station (ISS). The list of products and technologies that have their roots in space research is long, from memory foam to the in-ear thermometer, but in a world struggling to pay the bill from the financial crisis the billions of dollars spent on space exploration are increasingly hard to justify. ...

Yoga for jets: why planemakers prefer bent wingtips
Wed,2 May 2012 04:00 PM PDT
Reuters -  CHICAGO/PARIS (Reuters) - There are, so the industry saying goes, only three secrets in the commercial airplane business: the selling price, the production cost and the shape of the wing. Boeing and Airbus are testing that proverb to the limits as they squeeze improvements out of the wings of their most popular jets to make them more aerodynamic -- hunting down extra pennies per gallon of fuel savings for ultra-thrifty airlines. ...

Plant study flags dangers of warming world
Wed,2 May 2012 10:18 AM PDT
Reuters -  LONDON (Reuters) - Plants are flowering faster than scientists predicted in response to climate change, research in the United States showed on Wednesday, which could have devastating knock-on effects for food chains and ecosystems. Global warming is having a significant impact on hundreds of plant and animal species around the world, changing some breeding, migration and feeding patterns, scientists say. ...

Italy scientists say they have found oldest human blood
Wed,2 May 2012 08:26 AM PDT
Reuters -  ROME (Reuters) - Scientists examining the remains of "Otzi," Italy's prehistoric iceman who roamed the Alps some 5,300 years ago, said on Wednesday they have isolated what are believed to be the oldest traces of human blood ever found. The German and Italian scientists said they used an atomic force microscope to examine tissue sections from a wound caused by an arrow that killed the Copper Age man, who was found frozen in a glacier, and from a laceration on his right hand. ...

Can an African "green revolution" help feed the world?
Wed,2 May 2012 03:06 AM PDT
Reuters -  SABA SABA, Kenya, May 2 (AlertNet) - Her bare feet coated with mud, Sabena Gitau trudged down the rain-sodden hillside to her banana plantation, machete in hand. She chose and cut several giant bunches of bananas, which she strapped to a motorbike to be taken to nearby Saba Saba town, 77 km (48 miles) north of Nairobi, to be weighed, graded and sold. A decade ago, Gitau made the same 10 km trip a couple of times a month, on foot with her bananas on her back, earning about 420 shillings ($5) for the dawn-to-dusk trek. ...

"Green bullet" innovations aim to feed world of 9 billion
Wed,2 May 2012 03:02 AM PDT
Reuters -  LONDON, May 2 (AlertNet) - In flood-hit fields in the Philippines, farmers are testing a hardy new variety of rice that can survive completely submerged for more than two weeks. In Kenya's Kibera slum, poor urban families are turning around their diets and incomes just by learning to grow vegetables in sack gardens outside their doors. And in India, a push to help marginalized rural communities gain title to their land is leading to a significant drop in hunger. ...

Polar bears can swim vast distances, study finds
Tue,1 May 2012 07:35 PM PDT
Reuters -  ANCHORAGE, Alaska (Reuters) - Polar bears are capable of swimming vast distances, a potential survival skill needed in an Arctic environment where summer sea ice is vanishing, a study led by the U.S. Geological Survey showed on Tuesday. The study, published in the Canadian Journal of Zoology, tracked 52 female polar bears in the southern Beaufort Sea off Alaska. Between 2004 and 2009, a period of extreme summer-ice retreat, about a third of those bears made swims exceeding 30 miles in distance, according to the study results. ...

Silkworms and squid inspire smart materials
Tue,1 May 2012 04:39 PM PDT
Reuters -  (Reuters) - Car panels made of silkworm cocoons, clothing that can camouflage the wearer at the flick of a switch and a "smart" shirt with a phone and power source embedded in the fabric. Scientists, some with funding from the U.S. Air Force, have made breakthroughs that could eventually make all this reality. Research published on Wednesday reveals advances in materials science that could transform industries struggling with the rising cost and scarcity of raw materials and save lives in post-conflict countries still clearing minefields. ...

Icy Alpine caves setting for Mars mission tests
Tue,1 May 2012 06:52 AM PDT
Reuters -  VIENNA (Reuters) - Scientists were out of this world on Tuesday about tests in icy Alpine caves of the technology needed for a mission to Mars one day. "We have learned an infinite amount in the past three days," project leader Gernot Groemer from the Austrian Space Forum said of the 11-nation field test in the Dachstein region near Salzburg. Scientists picked the area - which Groemer called a "scientific playground" - for experiments because ice caves would be a natural refuge for any microbes on Mars seeking steady temperatures and protection from damaging cosmic rays. ...

FDA approves Glaxo cancer drug Votrient
Thu,26 Apr 2012 02:57 PM PDT
Reuters -  WASHINGTON (Reuters) - U.S. regulators gave the nod to GlaxoSmithKline Plc's Votrient for a type of sarcoma on Thursday, following a positive advisory panel vote last month. The U.S. Food and Drug Administration approved the pill for people with soft-tissue sarcoma who have already received chemotherapy. Soft-tissue sarcoma is a rare but aggressive form of cancer that afflicted about 11,000 Americans last year, 4,000 of whom died from the disease, according to the National Cancer Institute. The cancer begins in the muscles, fat or other tissues. ...
