Sometimes, the most significant scientific discoveries happen by accident. Scientists have long known that whole-genome ...

Ribosomes are the cell's heavyweight molecular machinery that produces proteins. It turned out, however, that in hungry yeast ...

Evolved macroscopic "snowflake" yeast from the MuLTEE experiment. The large size of the nuclei (yellow) and cells (cyan) are results of whole-genome duplication and aneuploidy.

These early observations came from biological studies of the cells of rapidly dividing fertilized frog eggs as well as mutant yeast cells that could not divide. The observations suggested that ...

The body's cells respond to stress-toxins, mutations, starvation or other assaults-by pausing normal functions to focus on conserving energy, repairing damaged components and boosting defenses.

Lurking within the genomes of nearly all species—including plants, fungi, and even humans—are genes that are passed from generation to generation with no clear benefit to the organism. Called "selfish ...

Recombinant yeast cells can be used as a vector to produce proteins that would normally be found in animals or plants. Recombinant yeast cells are used during DNA Recombinant technology as they ...

In contrast, in the polluted containers, the ones containing lactic acid, he observed "much smaller cells than the yeast." Pasteur's finding showed that there are two types of fermentation ...

Cell biologist Fred Chang, MD, PhD, has been named a fellow in the American Association for the Advancement of Science (AAAS), a highly esteemed lifetime honor within the scientific community.

Yeast is used to make alcoholic drinks. When yeast cells are reproducing rapidly during beer or wine production, the oxygen is used up. The yeast has to switch to using anaerobic respiration to ...
