Uncovering the mechanism behind high-temperature superconductivity -- a phenomenon with tremendous value to advances in energy efficiency and sustainability -- remains one of the greatest and most pressing puzzles in physics. Now, using precise laser pulses and atomically perfect 2-D materials, scientists have ruled out one...
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...
Scientists have developed an algorithm to predict how much can be learned in a large-scale DNA sequencing experiment -- with potential applications in every field of science. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/3...
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...
Scientists have demonstrated a quantum algorithm that performs a true calculation for the first time. Quantum algorithms could one day enable the design of new materials, pharmaceuticals or clean energy devices. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/l...
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 :...

Psychogenic diseases, formerly known as "hysterical" illnesses, can have many severe symptoms such as painful cramps or paralysis, but without any physical explanation. However, new research from the University of Cambridge and University College London suggests that individuals with psychogenic disease, that is to say physical...
