new neurons from inside
The brain may be able to repair itself from within, Duke researchers discoverJune 3, 2014 *[+]* In this artist’s representation of the adult subependymal neurogenic niche (viewed from underneath the ependyma), electrical signals generated by the ChAT+ neuron give rise to newborn migrating neuroblasts, seen moving over the underside of ependymal cells ( credit: O’Reilly Science Art) Duke researchers have found a new type of neuron in the adult brain that is capable of telling stem cells to make more new neurons. Neuroscientists have suspected for some time that the brain has some capac... mais »
Peer Review
Peer Review under Fire In the first decade of the 21st century, the number of scientific journal articleretractions rose more than 10-fold, raising serious questions about the peer-review process. Critics say that part of the problem is that study authors frequently omit some of the data from their papers, making it difficult for peer reviewers to accurately assess the work, especially when the papers employ complex, highly specialized techniques.

Search for Genes
Search Engine for Genes Will Boost Medical Research - TIME Staff 3:26 AM ET [image: 173543371]Getty ImagesWith the database, researchers will be able to see links between different genes, helping them find better treatments for everything from Alzheimer's to cancer Researchers at Virginia Tech have developed a search engine, called EvoCor, which finds genes that are functionally linked. By typing the name of a gene type into the database, the platform generates a list of genes that are compatible and likely to function together. This list of gene candidates can then give scientis... mais »
