This extraordinary cultural and natural diversity is an important source of life and inspiration for humanity and its preser...Tsunami + 1 year: Reviving exhausted fisheries should trump replacing boats, gear, experts say
...l Stephen Hall says that while delivery of aid has varied significantly from one location to another across the tsunami-affected region, infrastructure replacement is relatively easy to achieve compared with reformulating fisheries policy and modifying long-standing practices of communities to ensure sustai...Male elephants woo females with precise chemistry
...y exhausting musth episode, the ratio becomes more varied so that at the end of musth, the ratio is askewed toward the minus enantiomer, allowing other males and females to detect the ending of musth. The team then tested the effect the various enantiomer ratios had on the elephants. They examined ovulatin...Getting an evolutionary handle on life after reproduction
...which is what they found. Though overall lifespan varied among the populations, these variations stemmed from differences in time allotted only to reproduction. Postreproductive lifespan, in contrast, showed no signs of being under selection, and appeared to be what the authors called a "random add-on at t......ed how carbon dioxide levels in Earth's atmosphere varied over time millions of years ago by analyzing the proportions of different carbon and oxygen isotopes in prehistoric soils and animal teeth. In the new study, Cerling and colleagues analyzed hair in the tails of African elephants in Samburu National ......pear important in the laboratory may not be in the varied conditions of the field."

...variants with Rituxan showed that antibody binding varied with changes in the glycosylation structure. Moreover certain antibody glycoforms showed significantly increased antibody mediated cell killing compared to Rituxan. "By controlling the sugar structures on antibodies we have shown that the antibodies ...Alzheimer's found to be mostly genetic
...South Florida. Past estimates of Alzheimer's risk varied widely, with thehighest numbers sometimes greeted with skepticism. "Our finding confirms the higher estimates that have beensuggested previously. The important thing is that no onehas had this large a sample before," Gatz said, adding thesize was 10 ...A clue to core problem of neurodegenerative disease and cell death
...the mechanism that actually causes cell death have varied widely, puzzling scientists and leading them to ask whether Alzheimer's, Parkinson's, Huntington's and Creutzfeldt-Jakob diseases and familial amyotrophic lateral sclerosis (ALS) are related diseases or very different diseases. Northwestern Universi......ide. Interestingly, nitric oxide production levels varied among the diatoms. Some cells showed rapid increases in nitric oxide production while their neighbors showed delayed responses, suggesting that the signal to produce nitric oxide was propagating through the diatom population.
