Confirmed -- deforestation plays critical climate change role

...e data from 11 climate-carbon computer models. The results show that tropical forests continue to accumulate carbon through to the end of the century, although they may become less efficient at higher temperatures. "The new body of information shows considerable value in preserving tropical forests such a...

Asexual worm quickly adapts to soil contamination

...hether they are suitable for this purpose. The results of this study are important for the development of protection strategies for natural populations. This can be realised by focusing environmental management more on functions such as biomass turnover rate and less on the structure and biomasss of popu...

...e world that performs the procedure. The latest results of Duke's experience with this treatment of DiGeorge anomaly, published Tuesday, May 15, in the journal Blood, show that 75 percent of the babies who received a thymus transplant were alive after one year. The recipient of the first transplant, in 19...

Scientists seek useful traits in wild cottons

... massive thrips pressure on the cotton plants, and results in a lot of damage to those first four true seedling leaves," he said. "We measure the leaf damage, identify cottons that show thrips resistance and subject those to further tests." Sheehan raises Lygus bugs, a secondary pest of cotton, and ...

Scientists discover new life in the Antarctic deep sea

...of life of the global marine species. Our research results challenge suggestions that the deep sea diversity in the Southern Ocean is poor. We now have a better understanding in the evolution of the marine species and how they can adapt to changes in climate and environments." Dr Katrin Linse, marine bio...

Gene thought to assist chemo may help cancer thrive

...he tumors of patients undergoing chemotherapy. The results appear in the May 16 edition of the open access journal PLoS ONE. “P53 has long been recognized as a key player in directing chemotherapy-damaged cancer cells to self annihilate, but less attention has been paid to p53’s role in repairing damaged ...

Latent memory of cells comes to life

...the research group could simulate the experimental results and in this way gained insight into the mechanisms by which living cells with identical DNA can achieve extreme differentiation.
