Amazon trees much older than assumed, raising questions on global climate impact of region

...umbore points out, are contrary to the widely held view that tropical forests are highly dynamic. "In addition, the impact of logging activity in the Amazon region may be longer-lasting than we think," Trumbore added, "because it may take centuries for these forests to grow back to their full size." ...

Langerhans cells regulate immune reactions in the skin

...cine and immunobiology at Yale, "We now have a new view of these cells, not just as sentinels or stimulators of immune reactions as previously thought, but more as peacekeepers with the environment, which poses a constant challenge to skin. Most such challenges are not dangerous and do not warrant an immu...

Penicillin, amoxicillin: Step aside for strep throat treatment

... for the most severe cases. But most doctors would view a drug that fails in one out of four patients, as penicillin does in strep cases, as unacceptable, Pichichero said. To understand why the older drugs don't work as well, consider a child's throat as a battleground for many types of bacteria vying fo...

Bugs expose underground carbon traffic system 10 times more important than fossil fuel burning

...wenty mites from the order Collembola, which would view the AM mycelia as food stuff, were introduced to half of the cores. After another four weeks the grassland was exposed to a particular form of carbon dioxide (a stable isotope of carbon, 13C) for 7 hours, a technique called pulse labelling. Concentra...

Novel protein complex enables survival in hostile environment

...tudy goes a long way to dispelling this simplistic view and greatly extends our knowledge of their versatility." Methanogenesis is a microbial process in nature that produces methane, an energy resource and a green house gas. Sulfate reduction is also a microbial process where organisms turn sulfate int...

Zooming in on the protein-conducting channel

Researchers have gained the most detailed view yet of the heart of the translocon, a channel through which newly constructed proteins are inserted into the cell membrane. The process of transporting proteins across or into membranes is a critical function that occurs in every cell. Howard Hughes...

Penn study finds direct role for glial cells in brain cross-talk

Fruit fly research set to revolutionize study of birth defects

...nd of study is a revelation to the researchers who view it as an efficient model for the initial testing of "rescue" therapies to try to prevent birth defects. Scientists can study the effect of the drug on the genes of as many as three generations of fruit flies in a month using readily available scienti...

Mouse genome much more complex than expected

...ucture. 'Our study calls into question the classic view that one gene contains the information for exactly one protein,' Professor Zimmer explains. 'Mammals frequently use the selfsame place on the DNA several times over, as a partial blueprint, so to speak, for different proteins. It is becoming more and...

"There is this romanticized view of rainforests, yet the tropical dry forest is being forgotten even though the most fertile soils are there," said Sanchez-Azofeifa, who hails from Costa Rica.

Using a much larger sample size with clear evidence of exposure, our findings are internally consistent and almost exactly replicate the Dutch findings. Since the two...
