New research published in Genome Biology investigates genes that increase the life span of fruit flies in an effort to gain a greater understanding of the ageing process. The researchers from the University of Southern California and Harvard Medical School screened 10,000 fruit fly populations that were mutated.
Their results revealed that six populations of mutant flies lived 5-17% longer than normal. Furthermore, analysis of these long-lived flies showed that the extended life span
Penn State engineers have developed a low- cost, high-torque rotary motor, based on “smart” materials, that can be configured in a wide range of formats, including one as flat and thin as a CD case.
The inventors say that, in the flat format, the motor could be used to drive changes in the camber of airplane wings or fins, essentially shape-shifting the curvature of the wing or fin surface.
In other formats, the motor could work in tightly integrated spaces where other motors can
It seems that biologists know everything about the Alpine hare (Lepus timidus), particularly about its ration. However, the Yakut scientists, Anatoly Pshennikov and Vladimir Pozdnyakov have discovered a previously unknown method the hares employ in wintertime when they suffer from the lack of food.
Forage is scarce in winter in Yakutia. The Alpine hares are content to feed on bushes and young trees. If the distance between the ground and a thin twig is less than a meter, the hare bi
The key role of multidisciplinary research in developing a landmark intergovernmental strategy to combat air pollution across Europe will be considered by Professor Helen ApSimon of Imperial College London in her inaugural lecture, A lot of Hot Air – Transboundary Air Pollution Over Europe.
The new Professor of Air Pollution Studies will focus on how her research using computer modelling of air pollution contributed to the formulation of the Gothenburg protocol under the United Nations’ Con
As Rebecca Brown kayaked down the Nolichucky River in North Carolina one summer, she followed a path similar to many of her own study subjects. Seeds and other propagules often float downstream before settling along riverbanks. Rampant with change, these areas offer a nutrient-rich location for new plants, yet pose the danger of sweeping vegetation away in a flood. It is this high volatility that makes the area resource rich and perfect for invasive and native plants to put down their roots. In a stu
A long-standing debate in ecology has been the effect of diversity on the temporal stability of biological systems.
Ecological theory predicts that the stability of populations should decline as community diversity increases, in part, because population size is assumed to decline with community richness.
In the February issue of Ecology Letters, Valone and Hoffman, using an 11-year dataset, have shown that the temporal stability of 17 species of annual plants in natural communitie
