New target for chronic pain identified
Discovery of a phosphorylation event outside of the cell offers a new avenue for targeting chronic and pathologic pain, a new study reports.

Making chicken feathers
Does each cell in the embryo have a genetically predetermined fate, or are cell interactions important? Researchers have, for the first time, linked the two, showing how the tug of war between cells in the developing skin mobilizes a protein that triggers a genetic program to differentiate into a specific cell type, a feather follicle. This could provide tips on how to make more realistic artificial skin, with hairs and sweat glands.

Parasitic worms may lead to agricultural stem cell breakthrough
A plant parasitic nematode is a pest that parasitizes the roots of agricultural crops and creates nests called 'galls' which deprive plants of nutrition. Research on plant reactions to parasitic worms shows that parasitism activates plant stem cells which grow to form galls on their roots. This finding is expected to improve crop breeds and alleviate nematode damage, which is estimated to cost hundreds of billions of dollars each year worldwide.

Protein produced with electricity to alleviate world hunger
A batch of single-cell protein has been produced by using electricity and carbon dioxide, report scientists. Protein produced in this way can be further developed for use as food and animal feed. The method releases food production from restrictions related to the environment. The protein can be produced anywhere renewable energy, such as solar energy, is available.

Novel type of virus found in a lake in Central Finland links virus groups
Viruses are the most numerous biological entities -- where is life there are viruses. Still, only a small fraction of them have been structurally and biochemically characterized.

Massive simulation shows HIV capsid interacting with its environment
It took two years on a supercomputer to simulate 1.2 microseconds in the life of the HIV capsid, a protein cage that shuttles the HIV virus to the nucleus of a human cell. The 64-million-atom simulation offers new insights into how the virus senses its environment and completes its infective cycle.

Pause to read the traffic sign: Regulation of DNA transcription in bacteria
The survival of the cell is -- apart from other important aspects -- a question of timing. Scientists have now identified the different parts of this mechanism and introduced a model of the process.

New bacterial defense mechanism of the CRISPR-Cas system uncovered
Researchers have found an unprecedented defense mechanism by which bacteria defend themselves against invading viruses. When the bacterial immune system gets overwhelmed, the CRISPR-Cas system produces a chemical signal that activates a second enzyme which helps in degrading the invaders' genetic material. This process is very similar to an antiviral mechanism of the human innate immune system.
