Medical researchers have deepened the understanding of the environment within bone marrow that nurtures stem cells, this time identifying the biological setting for specialized blood-forming cells that produce the infection-fighting white blood cells known as T cells and B cells. Fuente :...

Scientists have identified several genes linked to human neurological disorders, including Alzheimer's disease, Parkinson's disease and spinal cord injury, in the sea lamprey, a vertebrate fish whose whole-genome sequence. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/3...

Small stretches of DNA in the human genome are known as "pseudogenes" because, while their sequences are nearly identical to those of various genes, they have long been thought to be non-coding "junk" DNA. But now, a new study shows how pseudogenes can regulate the activity of a cancer-related gene...

The origin of an innate ability the brain has to protect itself from damage that occurs in stroke has been explained for the first time. Researchers hope that harnessing this inbuilt biological mechanism, identified in rats, could help in treating stroke and preventing other neurodegenerative...

Two new articles describe how the CPBE1 protein "takes the brakes off" the production of proteins associated with the cell switch from being healthy to tumorous. The study highlights CPEB proteins as promising targets, thus opening up a new and unexplored therapeutic window. The lab has developed a...

Researchers have demonstrated that graphene is able to convert a single photon that it absorbs into multiple electrons that could drive electric current -- a very promising discovery that makes graphene an important alternative material for light detection and harvesting technologies, now based on...

Researchers have identified a new so-called pseudogene that regulates the tumor-suppressing PTEN gene. They hope that this pseudogene will be able to control PTEN to reverse the tumor process, make the cancer tumour more sensitive to chemotherapy and to prevent the development of resistance. The findings can be of significance...

The islands Reunion and Mauritius, both well-known tourist destinations, are hiding a micro-continent, which has now been discovered. The continent fragment known as Mauritia detached about 60 million years ago while Madagascar and India drifted apart, and had been hidden under huge masses of lava. Fuente :...
