A genetic change in the protein eEF2K creates resistance to epileptic attacks, thereby creating the possibility of a new treatment for the disease, show the surprising results of a new study.

Enough is enough: Stem cell factor Nanog knows when to slow down

Posted: 25 Nov 2016 05:42 AM PST

The transcription factor Nanog plays a crucial role in the self-renewal of embryonic stem cells. Previously unclear was how its protein abundance is regulated in the cells. Researchers now report that the more Nanog there is on hand, the less reproduction there is.

Three rings stop cell division in plants

Posted: 25 Nov 2016 05:42 AM PST

Arising from a collaboration between plant and animal biologists, and organic chemists, a research group has succeeded in developing a new compound, a triarylmethane that can rapidly inhibit cell division in plants. This compound was found to selectively inhibit cell division in plant cells with respect to animal cells. Having a reversible cell inhibiting property, this triarylmethane could be a potential candidate for developing new agrochemicals that can control plant growth.

Starch now created from yeast

Posted: 23 Nov 2016 11:32 AM PST

Starch is only produced by plants and algae. Now, it can also be produced by yeast - or, at any rate, by the yeasts in labs, report scientists. The researchers have succeeded in implanting yeast with the machinery that plants use to create this stored form of glucose.
