Tibetan antelope slowly recovering, WCS says

...has ever taken place due to a sprawling range that spans more than 250,000 square miles. The team also counted more than 1,000 wild yak, a relatively high number for a species that's far more endangered than the chiru, due to hunting and hybridization with domestic yak. The group saw an increase in wil...

Protein fragments sequenced in 68 million-year-old Tyrannosaurus rex

...rmation, a barren fossil-rich stretch of land that spans several states, including Wyoming and Montana. Schweitzer and colleagues reported in 2005 that they had found evidence of soft tissue inside the fossilized femur, a discovery widely covered. After seeing one such story in the New York Times, Cantley ...

Prehistoric mystery organism verified as giant fungus

...o 350 million years ago. During this period, which spans part of the Silurian and Devonian periods of geologic time, terrestrial Earth looked quite alien in comparison to the modern world. Simple vascular plants, the ancestors of the familiar conifers, ferns and flowering plants of today, began to diver...

Billions of dollars saved in US by polio vaccination

...sis. The history of polio vaccination in the U.S. spans over 50 years and includes different phases of the disease, multiple vaccines, and a sustained significant commitment of financial resources. Lead author of the study, Kimberly Thompson, associate professor of risk analysis and decision science at HS...

Meat and two neutrons -- the key to a longer life

... of elements). In initial experiments, worms' life spans were extended by 10%, which, with humans expected to routinely coast close to the centenary, could add a further 10 years to human life. Food enhanced with isotopes is thought to produce bodily constituents and DNA more resistant to detrimental p...

Shrinking ponds signal warmer, dryer Alaska

... subarctic boreal region of Interior Alaska, which spans more than 5 million square kilometers bounded on the north by the Brooks Range and on the south by the Alaska Range. To contrast the semi-arid, subarctic sites of discontinuous permafrost in Interior Alaska, the authors also selected a study area in ...

Dinosaurs -- stones did not help with digestion

...ht and corresponding masses of gastric stones also spans four orders of magnitude, from the 17 gram robin to the ostrich,' says Oliver Wings, who moved from Bonn University to Tübingen only recently. Yet what else were the dinosaurs' gastric stones used for? The researchers presume that they were accide...

Better sludge through metagenomics

His research spans some forty years of international professional practice in water and wastewater chemistry and wastewater treatment for government, municipalities, and industry. He has specialized in the chemical precipitation of phosphate from wastewater and sludge...

Biotech cotton provides same yield with fewer pesticides

...mmercial cotton fields in a region of Arizona that spans about 2,500 square miles (6,600 square kilometers). Much of the field and lab work was done by Manda G. Cattaneo as part of her master's research at UA. Cattaneo is now an extension entomologist at Texas A&M University in College Station. The...

New tiger report release: Tiger habitat down from just a decade ago

...t tigers over the last 10 years. "As tiger range spans borders, so must tiger conservation," said Eric Dinerstein, chief scientist and vice president of conservation science at World Wildlife Fund. "Asia's economic growth should not come at the expense of tiger habitat and the natural capital it protect...

Creating a window on 'oceans in motion'

...The OTN plans a highly interconnected network that spans 14 ocean regions: The Arctic and Southern Oceans, the Indian Ocean (East, West), the Atlantic (NE, NW, SE, SW), the Mediterranean, and the Pacific (NE, NW, SE, SW and Mid-ocean). The group says funding sought from Canada of roughly US$32 million to...

Scientists find Antarctic ozone hole to recover later than expected

...ses containing chlorine and bromine that have life spans in the atmosphere ranging from 45 to about 300 years, are affecting ozone. This new prediction model is a very useful step forward to refining our understanding of ozone hole recovery time scales." The researchers included ozone data from the Total ...

The giant protein titin helps build muscles

...n is anchored in the Z-disk and is so long that it spans half the length of a sarcomere. Its size and position ?putting it into contact with all the majorcomponents of sarcomeres ?suggests that it might help in their assembly.

Stanford study of owls finds link in brain between sight and sound

...ain uses a common strategy to focus attention that spans different types of animals and different parts of the brain. "This paper opens the floodgates for studying a wide range of species," Knudsen said. "The fundamental mechanisms are probably going to be the same in all vertebrates, as even frogs and fi...
