Science's breakthrough of the year -- The Poincar Theorem
...s year. The Antarctic and Greenland ice sheets are losing ice, at an ever faster rate, to the oceans. Fishy First Steps: The discovery of a fossil fish with sturdy, jointed fins made a big splash in 2006. The fish is the closest known kin to limbed vertebrates and provides a window into how life left the ......" founded by bacteria to combat antibiotics may be losing ground. By combining key properties of two different types of weapons used by the innate defense systems of organisms, a team of scientists at the Weizmann Institute of Science has managed to design a more powerful weapon, hoping that this will provi...Producing medicines in plant seeds
...t. The seeds can be stored for a long time without losing the produced protein's effectiveness, so that a reserve can always be kept on hand. This means that the proteins can be isolated from the seeds at the moment that they are actually needed. With production in leaves, for example - or with conventional...'Speechless' and 'Mute' help break the silence of the leaves
...n't evolved this ability, which protects them from losing too much moisture. The leaves and stems of land plants are dotted with the "tiny mouths," called stomata. When open, stomata allow the plant to take in carbon dioxide gas needed for photosynthesis and allow moisture to evaporate, pulling water from ...Gene knockouts reveal FoxOs' vital functions in cancer defense, health of stem cells
...scription factors," he said, dividing too rapidly, losing their ability to renew themselves, and dying out. "This means that FoxOs contribute to the longevity of stem cells, and if you take them away, you dramatically shorten stem cells' lives." Looking further, Gilliland and his colleagues found that the...Some brain-damaged patients quit smoking with ease, researchers report in Science

Because the patients reported losing the urge to smoke so suddenly and without difficulty or relapse, Bechara and his colleagues concluded that insula damage reduced the patients' actual urge to smoke rather than reducing the pleasurable experience, or "reward," associated with smoking....Weight-loss supplement shows good and bad traits

In contrast, Stern says, the costs of reducing greenhouse gas emissions can be limited to around 1% of global GDP each year.

"There are conditions where a lot of cells die by what we call apoptosis and, in these cases, it could be that ceramide is elevated and that causes good cells to die," says Dr. Bieberich.

...e originally flanked by intron-exon boundaries. On losing the introns, the selection constraint has apparently been released (as splice enhancers are no longer needed). This also implies that, in the multi-exon forms of the proteins, the sequences were not optimized for their biological functions but have i...Reversal of symptoms in an autism spectrum disorder

... the disease, said Bowers. However, once you start losing neurons, things become very difficult, because the body doesnt readily replace them due to their very large size. If we could find a marker, early on, to indicate when the patient first has the disease, then the new drug or drugs that we hope to dev...Stem cells determine their daughters' fate

It remains to be proven whether ISCs require a specific microenvironment created by neighboring cells, known as a niche, as other types of stem cells in Drosophila and mammals do. Understanding such a niche could have hug...Cellulosic ethanol: Fuel of the future?

For a lucky subset of vertebrates, losing an appendage is no big deal.
