Powerful systems biology

An international team of researchers headed by ETH-Zurich scientists has demonstrated for the first time how to extract testable hypotheses from a vast amount of different measurement data for cells that are about to change. ...

Tracking genes' remote controls

As an embryo develops, different genes are turned on in different cells, to form muscles, neurons and other bodily parts. Inside each cell's nucleus, genetic sequences known as enhancers act like remote controls, switching ...

Transcriptional elongation control takes on new dimensions

Life is complicated enough, so you can forgive the pioneers of DNA biology for glossing over transcriptional elongation control by RNA polymerase II, the quick and seemingly bulletproof penultimate step in the process that ...

Parental controls on embryonic development?

When a sperm fertilizes an egg, each contributes a set of chromosomes to the resulting embryo, which at these very early stages is called a zygote. Early on, zygotic genes are inert, so embryonic development is largely controlled ...

New light shed on cell division

Genes control everything from eye color to disease susceptibility, and inheritance - the passing of the genes from generation to generation after they have been duplicated - depends on centromeres. Located in the little pinched ...

Researchers fight world hunger by mapping the soybean genome

In 2009, soybeans represented an almost $30 billion industry in the U.S. alone, making soybeans the second-most profitable crop next to corn. Worldwide, soybeans have been used in human foods and livestock feed for centuries ...

Epigenetic mark guides stem cells toward their destiny

(PhysOrg.com) -- Not all stem cells are completely blank slates. Some, known as adult stem cells, have already partially embraced their fates and are capable of becoming only cells of a particular type of tissue. So how do ...
