Sunshine pill for prostate cancer in 2009

...o effect. Novacea, the company that makes Asentar, produced a novel formulation that reproduces the healing effect without the dangerous side-effects of a vitamin D overdose. If the on-going phase III trial goes to plan, the new drug should be available in 2009, reports Chemistry & Industry, the magazine...

...cial? ''It uses less water per gram of biomass produced than other plants,'' he said. ''For example, to make a pound of alfalfa or spinach requires about 600 pounds of water, while to grow a pound of Miscanthus requires only about 200 pounds of water.'' According to Somerville, Miscanthus produces abou...

Strawberry daiquiris -- the extra-healthy cocktail?

...y work by helping to mop up damaging free radicals produced naturally during a person’s normal metabolism. Those who aren’t keen on strawberry daiquiris might be relieved to know that the scientists found similar results with blackberries, meaning that a blackberry-crowned champagne cocktail might achieve...

Birth rate, competition are major players in hominid extinctions

...e food. Paranthropus could not compete because it produced one offspring a year at most, while the others had large litters and could increase their populations at a much faster rate. Paranthropus simply could not compete reproductively and could not alter its choice of food. "We find that the early memb...

Freeze! Scientists film proteins at work by freezing them at different states

...l living organisms have to fight oxidative stress, produced by outflows of the oxygen metabolism. In humans, about 2% of the oxygen used to breathe is transformed into this toxic “superoxide radical?molecule, instead of water. This production is increased in people affected by neurodegenerative diseases such ...

Small molecule dervived from Rb2/p130 could act as cancer therapeutic

...named Spa310. The molecule that was synthetically produced in the laboratory was introduced into mice that had been injected with tumor cells. "Tumor growth was inhibited and the tumors began to reduce in size until they disappeared," Giordano said. Giordano said because of the intrinsic nature of the ...

Scientists unlock secret of what makes plants flower

Antibody signal may redirect inflammation to fuel cancer

...ignal from serum in the blood -- often an antibody produced by a B cell in the separately evolved "acquired" immune system. Now UCSF researchers have found that in the presence of precancerous tissue, leukocyte antibody receptors can also be activated to turn on a dangerously different program: inducing l...

Biologists produce global map of plant biodiversity

...n Diego and the University of Bonn in Germany have produced a global map of estimated plant species richness. Covering several hundred thousand species, the scientists say their global map is the most extensive map of the distribution of biodiversity on Earth to date. The map, which accompanies a study publi...

Biodiesel won't drive down global warming

...e engine. By contrast, two-thirds of the emissions produced by rapeseed derived biodiesel (RME) occur during farming of the crop, when cropland emits nitrous oxide (N2O), otherwise known as laughing gas, that is 200-300x as potent a greenhouse gas as CO2. The results of this analysis should have big implic...

Mosquito genes explain response to climate change

...ity of Oregon researchers studying mosquitoes have produced the first chromosomal map that shows regions of chromosomes that activate ?and are apparently evolving ?in animals in response to climate change. The map will allow researchers to narrow their focus to identify specific genes that control the seaso...

Living with water scarcity -- world must act now

...ery day, depending on our diet and how the food is produced ?far more than the 2 to 5 litres we drink every day" says Molden. A heavy meat diet requires much more than a vegetarian diet. In developed countries water scarcity poses no threat to what appears on the dinner plate. In contrast, the relation...

The connector rotation hypothesis? Phage do not pack their DNA by rotation

...t on them and recorded the pattern of fluorescence produced in two channels at right angles to one other. If the connectors had been rotating, they would have seen a sine wave-like fluctuation in intensity in both channels with a phase shift of 90 degrees. They did not see the sine waves, and mathematical ...

Neural bottleneck found that thwarts multi-tasking

The two tasks consisted of pressing the appropriate computer key in response to hearing one of eight possible sounds and uttering ...
