Research discovers frequent mutations of chromatin remodeling genes in TCC of the bladder
BGI, the world's largest genomics organization, Peking University Shenzhen Hospital and Shenzhen Second People's Hospital, announced today that the study on frequent mutations of chromatin remodeling genes in transitional cell carcinoma of the bladder was published online in Nature Genetics.

Mutations not inherited from parents cause more than half the cases of schizophrenia
Columbia University Medical Center researchers have shown that new, or

UMass Amherst research team discovers new conducting properties of bacteria-produced wires
The discovery of a fundamental, previously unknown property of microbial nanowires in the bacterium Geobacter sulfurreducens that allows electron transfer across long distances could revolutionize nanotechnology and bioelectronics, says a team of physicists and microbiologists at the University of Massachusetts Amherst.

How yeast chromosomes avoid the bad breaks
Whitehead Institute researchers have discovered how yeast cells protect themselves against a novel type of chromosome fragility that occurs in repeated DNA during meiosis -- the cell division that produces spores in fungi or eggs and sperm in plants and animals.

UNC-Duke ties lead to collaborative finding about cell division & metabolism
A new finding based on multiple collaborations between UNC and Duke scientists over several years points to new avenues for investigation of cell metabolism that may provide insights into diseases ranging from neurodegenerative disorders like Parkinson's and Alzheimer's disease to certain types of cancers.

Cell-based alternative to animal testing
European legislation restricts animal testing within the pharmaceutical and cosmetic industries and companies are increasingly looking at alternative systems to ensure that their products are safe to use.

Bullying may contribute to lower test scores
High schools in Virginia where students reported a high rate of bullying had significantly lower scores on standardized tests that students must pass to graduate, according to research presented at the 119th Annual Convention of the American Psychological Association.

New resource to unlock the role of microRNAs
The first mammalian microRNA knockout resource -- mirKO -- will be released.

Brain's map of space falls flat when it comes to altitude
Animal's brains are only roughly aware of how high-up they are in space, meaning that in terms of altitude the brain's 'map' of space is surprisingly flat, according to new research.

The nanoscale secret to stronger alloys
Researchers at Lawrence Berkeley National Laboratory's National Center for Electron Microscopy have solved the mystery of one of the most promising aluminum alloys ever for strength, hardness, lightness, and resistance to corrosion and heat.
