Phase transition in bilayers could affect their performance
...g the properties of supported bilayers through the incorporation of additional constituents, the scientists said. In this case, the defects would serve as portals through the membrane, where proteins or other components could be introduced, and then encased by raising the temperature. "Our experiments have shown ...Coral layers good proxy for Atlantic climate cycles

"When we look at the averaged annual data from 1935 to about 1994, we see it has the shape of a sine wave," says Greer. "It is periodic and has a significant pattern of oxygen isotope composition that has a peak at about ev...Alcohol's effects on testosterone

They found that concentrations of testosterone increased fourfold in the frontal cortex and threefold in the plasma of the un-operated rats 30 minutes after alcohol administration. AD...Diabetes therapies and liquid memory may develop from micro fluid research, Science researchers say
...gical and biochemical systems," said Groisman. The incorporation of liquid polymers into fluidics has enabled researchers to escape the demands of inertia and shrink the size of circuits. This miniaturization trend will continue, according to the authors....Seven CD-ROM global GIS data set available from AGI

Regional CD-ROMs are available for North America, Europe, Central and South America, Africa, North Eurasia, South Asia, and the South Pacific. The world atlas on DVD-ROM will be available in mid-2003. The Global GIS ...Salt controls size of DNA structures, could improve gene therapy

In the study reported in PNAS, Hud and his Ph.D. students Christine Conwell and Igor Vilfan also describe using the positively charged, inorganic molecule hexammine cobalt (III) to condense a DNA molecule contain...New guidelines can help health officials better predict and control dengue epidemics
... findings are meant to "provide incentives for the incorporation of types of early warning systems, which may have substantial benefits even if they are not always 100% accurate." In particular, systems that provide some indication of an increased likelihood of higher levels of dengue transmission may warrant more...Rocks could reveal secrets of life on Earth and Mars

The three-year initiative will be carried out by geologists and bioengineers at the University of Aberdeen and the University of Glasgow, with funding from the UK's Engineering and Physical Sciences Re...Budding viral hijackers may co-opt cell machinery for the getaway
...ndophilin-2, was not there. This suggests that the incorporation of selected proteins is unlikely to be accidental. Endophilin-2's normal role is to increase the curvature of the cell membrane during endocytosis. Further examination of how retroviruses use endophilin-2 will not only tell us more about the normal p...Gulf between rich, poor will grow if high-profile nanotechnology opponents prevail: ethics experts

This process involves the gradual incorporation of carbon from dead plants and microbes into stable organic matter called humus, which is responsible for the dark color in many soils.

...ers in the presence of a different enzyme, and the incorporation of those bases into the polonies is monitored with a scanning machine. This produces a read-out of the DNA sequence from each polony.

The incorrect amino acid, while different in the six mutations, had in common that all appeared to either jam the pump's molecular machinery, cause unstable misfolding in the protein,...Improving crops without genetic modification natural variation holds the key

In further analyses, Hsu confirmed that bacterial polymerase would behave just as did the human polymerase in preferring to incorporate the mismatch and failing to recognize it.
