The ability to make cells do our bidding would be a major advance in everything from drug production to biofuels, but it’s difficult to hack into nature and make cells obey. A team of Swiss researchers have one way to do it: Create cyborg cells connected to, and controlled by, a computer.
Dieters know the powerful temptations of just seeing or smelling food. Certain odors might have such a strong effect as to actually change the body's metabolism and lead to an early grave. At least, that's the case for fruit flies on a diet, according to Science Now.
In an interesting experiment, researchers sheathed living yeast cells in armor of silica. The cells survived, and emerged as unusual armored versions of themselves that could become building blocks for nanotech applications.
As any brewer will tell you, the yeast used to make beer tends to bunch up during fermentation. However, despite thousands of years of brewing and decades of genetic research on yeast, no one was able to explain why yeast stuck together. Now, not only has the gene behind the clumping been discovered, but that gene also offers an interesting look at how life may have become multicellular, and provides a new example of an important evolutionary theory.
Scientists find the stuff that makes bread oh-so-tasty also may cure everything from Lou Gehrig's disease to aging

You know that humans have used yeast for thousands of years for baking and brewing, but did you know that it’s also prized for its applications in medical research?
The metabolic processes of yeast cells are similar to mammal cells, and since yeast reproduces quickly, experimental results can be obtained much faster than they would using animals. Yeast’s rapid reaction time has allowed scientists to put all sorts of research in fast-forward, with the aim of efficiently developing new disease treatments.
