Of enzymes and aging: Tryptophan metabolism plays key role in aging and age-related neurological diseases

Of enzymes and aging: Tryptophan metabolism plays key role in aging and age-related neurological diseases | Neurobiology | Scoop.it
(Medical Xpress)—In the battle against aging and age-related neurological diseases such as Parkinson's and Alzheimer's, a key factor has long appeared to be the toxicity of proteins which tend to aggregate.

Biological measurement beyond the quantum limit : Nature Photonics : Nature Publishing Group | Neurobiology | Scoop.it
Researchers use squeezed light to track the constituents of yeast cells with a performance that overcomes the quantum noise limit. This approach allows for the utilization of low optical power, which helps to minimize cell damage.

Parasitic DNA: Complete bacterial genome discovered inside genome of a Drosophila fruitfly

Parasitic DNA: Complete bacterial genome discovered inside genome of a Drosophila fruitfly | Neurobiology | Scoop.it

Scientists at the University of Rochester and the J. Craig Venter Institute have discovered a copy of the entire genome of Wolbachia, a bacterial parasite, residing inside the genome of its completely different host species Drosophila Ananassae, the fruitfly. To isolate the fly’s genome from the parasite’s, the flies were fed with a simple antibiotic, killing the Wolbachia, but Wolbachia genes were still there. The scientists found that the genes were residing directly inside the second chromosome of the insect, and that some of these genes are even transcribed in uninfected flies, so that copies of the gene sequence are made in cells that could be used to make Wolbachia proteins.
