Are yeast cells bringing us a step closer in treating obesity?
...od targets for new medicines to compensate for the surplus or shortage of a particular sugar. Yeast as model for humans The VIB scientists are conducting their research on yeast proteins. It often turns out that the proteins found in yeast have a similar variant in human cells. This makes yeast an excellen...Muon opportunists: Detecting the unseen with natural probes
...ough the pyramid. The team will be looking for any surplus of muons striking a portion of its detector array compared to the background flux. That would be an indication that voids in the pyramid have allowed more particles to pass through to the detectors than expected.

That means they have more tools to lie coupled with fewer moral restraints than normal people, Raine said.

...rain, like grooves on a record," said Silva. "But surplus Ras tips the balance between switching signals on and off in the brain. This interrupts the delicate cell communication needed by the brain to record learned information." The UCLA team began searching for a safe drug that would zero in on Ras and o...Overproducing leptin receptors in fat cells may be key to halting weight gain
... mice's high levels of leptin receptors caused all surplus calories to be burned rather than stored. "They were overfed tremendously and did not get obese. Our control animals were fed the same diet and gained an enormous amount of weight," Dr. Wang said. "If we could prevent the disappearance of leptin rece...New egg freezing technique offers hope to hundreds of women
