Plants do not emit methane

...rting in New Phytologist, Tom Dueck and colleagues present their results and conclude that methane emissions from plants are negligible and do not contribute to global climate change. The consortium brings together a unique combination of expertise and facilities enabling the design and execution of a novel...

How T lymphocytes attack

... scientists noted that these defenders were always present at the periphery, but that the presence of the antigen was essential to in-depth penetration, leading to effective tumour elimination. These results were validated in two types of experimental tumour generated from two lines of cancer cells. It...

Satellites shed light on global warming

...chive of uniformly processed data from 1991 to the present day, which is due to be launched later this year, it will soon be possible to provide a definitive statement of the rate at which global temperatures have been changing and how the variability of our climate has been changing," Llewellyn-Jones said. ...

With cellulosic ethanol, there is no food vs. fuel debate according to MSU scientist

...at are made from renewable resources. Dale will present his findings today at the American Chemical Society annual meeting in Chicago. "We grow animal feed, not human food in the United States," Dale said. "We could feed the country's population with 25 million acres of cropland, and we currently have ...

'Hidden-hero' microbes in soil, water may help naturally clean toxic sites

... a genetic database of genes of organisms that are present in the Oak Ridge site's subsurface. "With the genetic database and associated cutting-edge genomics techniques, my lab will determine and predict the functioning or metabolism of subsurface microbial groups that catalyze key chemical reactions for...

Vaccine to cope with viral diversity in HIV

...culties in producing a vaccine. David Nickle et al present here an efficient algorithm to develop vaccines that cope with the diversity of HIV or other variable pathogens. This computational method clarifies and analyzes the variation found in the strains of the virus by describing the molecules which stimu...

Dinosaur extinction didn't cause the rise of present-day mammals, claim researchers

... million years after the dinosaurs were wiped out, present day mammals kept a very low profile, while these other types of mammals were running the show. It looks like a later bout of 'global warming' may have kick-started today's diversity ?not the death of the dinosaurs. "This discovery rewrites our und...

New insights into autoimmunity and depression

... system in SLE is another intriguing aspect of the present study," notes its leading author, Yehuda Shoenfeld, M.D., while emphasizing the need for further investigation through large-scale clinical studies. "Elucidating the mechanisms by which anti-ribosomal P induces behavioral changes may lead to novel t...

UCLA: How does your brain respond when you think about gambling or taking risks?

...6 issue of the journal Science, UCLA psychologists present the first neuroscience research comparing how our brains evaluate the possibility of gaining versus losing when making risky decisions. Participants in the study, mostly UCLA students in their 20s, were given $30 and then asked whether they would ag...

100 percent juices found as beneficial to health as fruits and vegetables

...ust the fiber but also from antioxidants which are present in both juice and the whole fruit and vegetables. This 2006 review of the literature states, “When considering cancer and coronary heart disease prevention, there is no evidence that pure fruit and vegetable juices are less beneficial than whole ...

Music genes and musical geniuses

A book of abstracts will be distributed at the beginning of the Workshop and the proceedings published in electronic and/or paper format after the event. In addition to the round table discussions and meetings with s...

'The eyes have it' -- Autism research yields surprising results

...revious research are largely based on methods that present static photographs to participants. Our study indicates that a more accurate measure of the abilities of those with autism can be obtained through the use of sophisticated digital imaging techniques with animated facial expressions." The study com...

Ape gestures offer clues to the evolution of human communication

...nobos and chimpanzees as well as humans likely was present in the last common ancestor," said Pollick. "A good example of a shared gesture is the open-hand begging gesture, used by both apes and humans. This gesture can be used for food, if there is food around, but it also can be used to beg for help, for s...

Monitoring poisons in the environment -- a woolly matter

Heavy metals are present in variable amounts in the natural environment in ...er Sneddon (Liverpool John Moores University) will present the results of a pilot study assessing the use of upland sheep wool as a bio-monitoring device for n...

Dig deeper to find Martian life

...ion environment on Mars and its effect on past and present life. This is the first study to take a thorough look at how radiation behaves in the atmosphere and below the surface and it’s very relevant to planned missions. The best chance we have of finding life is looking in either the sea at Elysium or fres...

Chronic pain up almost 40 percent among US workers in past decade

Salmonella survives better in stomach due to altered DNA

...hogen. Examining which genetic characteristics are present in an infectious Salmonella (in this case the DT104 type) can reveal how this pathogen has become stronger and caused more outbreaks. This information can also be used to make a less dangerous variant of this infectious Salmonella. Such a harmless va...

Stress hormones may play new role in speeding up cancer growth

...is showed that the receptors for this hormone were present on cells in Glaser's cell line, but that might have been just a laboratory aberration in the tissue cultures. "We needed to see how relevant this finding was to what happened with actual tumors," he said. Glaser asked colleagues for samples of act...
