Brown is principal investigator of the institute, which will receive $7.5 million over the next five years-$6.7 million from NSF and $800,000 from the Department of Energy. The co-principal investigators from Stanford...For yeast, a DNA break ensures sex switch for a grandchild
...heir progeny receive the same genomic DNA, yet the fate of the cells of the next generation will not be identical. One of the two daughter cells will produce a granddaughter cell that has switched its sexual mating type. Two decades ago, researchers proposed that a chromosomal imprint at the mating-type l...New Royal Society journal studies

Our results showed that the workers produced eggs according to the theory while they also removed nestmate-workers' eggs contradicting the theory. Conflict over reproduction between workers using an unk...Tiny exosomes extracted from donor cells may be 'magic bullet' for drug-free transplants
...li and colleagues sought to do so by following the fate of exosomes that they extracted from dendritic cells of one mouse strain and injected into the bloodstream of mice of a different strain. The exosomes were labeled with a dye, and methods such as flow cytometry, confocal microscopy and immuno-electro...Illegal tuna fishing and farming leads to demise of species

Sawyers received a phone call from Bristol-Myers Squibb -- and BMS-354825's reincarnation as a cancer drug was under way. As Sawyers is quick to point out, only time...Iceberg poses no threat to Antarctic personnel
... roughly 1-3 three kilometres per day. The berg's fate is unclear, as it depends on unpredictable winds, tides and other forces, but possibilities include colliding with the floating Drygalski Ice Tongue or continuing north, eventually to melt. If it's the former, the impact with the ice tongue could com......s known to be important in a number of neural cell fate determination and developmental processes, and is ... shows the ability to sense a small change in cell fate and amplify it, acting as a sort of contrast enhancement mechanism in cell fate determination.

... Mexico, considerable attention has focused on the fate of the now highly polluted water body. After massive fish kills and avian mortality in the 1990s, federal agencies targeted the lake for one of the nation's largest restoration projects. Wood says the discovery also shows that the Salton Sea, with it...Unusual reproductive behavior of odd ants surprises scientists

...uppression of differentiation, which maintains the fate of the cell as a germline stem cell," Lin said. In the cystoblast cell, the signal from piwi is no longer effective because this cell is detached from niche cells, which allows for the expression of the bam gene, which in turn represses the activity...New insight into regulation of blood stem cells
...ifferentiation. The ability to influence stem cell fate decisions would be expected to have a major impact on the field of stem cell therapy and to provide important in vitro model systems for the identification of genes and compounds that can be used to regulate the process of stem cell differentiation."...When does a mole become a melanoma?
..." adds Zon. "We can track a cancer and follow the fate of individual cells as the tumor grows and spreads." Now that the zebrafish model has been created, Zon's team will use it to examine how melanomas metastasize, and to look for other gene mutations besides the p53 mutation that participate in transfo...Are IVF embryos starved of a vital ingredient?
