Nicotine rush hinges on sugar in neurons

...old its shape, Chen said. The water molecule may enable the receptor to alter its shape in counterbalance to the bending hinge, said Chen, who explained, “Think of it as a lubricant.” Previously studied “homologs” of nAChR – proteins that share its structure but not its signaling function – are entirely...

CSIRO scientists join fight to save 'Tassie devil'

Research team identifies new Alzheimer's gene

... Phoenix-based Kronos Optimal Health Company, will enable Kronos to develop a test that aids in clinical diagnosis and help determine a person’s genetic predisposition for developing Alzheimer’s disease. “This discovery allows us to accelerate the development process for creating a new diagnostic test th...

Study shows big power of small RNAs, not just proteins, in halting cancer

...ve identified a family of micro RNAs (miRNAs) that enable a critical tumor suppressor network, called the p53 pathway, to fight cancer growth. “At CSHL, we are moving simultaneously on several fronts to understand the p53 pathway because damage to this pathway is something that almost all cancers have in c...

Herpes virus hijacks DNA repair process

...he DNA repair response helps viral replication may enable us to develop novel strategies to treat infection." The paper appears online this week in Cell Host & Microbe. Scientists have known for some time that viral infection of cells activates the DNA damage response. But researchers had assumed th...

454 sequencing identifies HIV drug resistance at early stage

...ands of long clonal sequence reads that accurately enable the sensitive detection of rare mutations” explained Egholm Michael, Ph.D. vice president of research and development at 454 Life Sciences. “Ultra Deep Sequencing provides an essential tool for research on viral diseases and their treatments. The ab...

How brain pacemakers erase diseased messages

... processes underlying deep brain stimulation could enable physicians to better fine-tune electrical implants, Grill said. That could be particularly useful for zeroing in on effective settings for implants used to treat diseases, such as epilepsy, in which seizures occur only sporadically, as well as condit...

How the brain's backup system compensates for stroke

...brains of stroke victims can quickly reorganize to enable the beginning of recovery of movement. Jacinta O'Shea and colleagues at the University of Oxford reported their findings in the May 3, 2007 issue of the journal Neuron, published by Cell Press. In their experiments, the researchers focused on a r...

How to steer a moving cell

...t developed in Klemke’s lab is the first method to enable researchers to study the entire network of signaling proteins. "To find out what goes wrong during metastasis, we need to understand how the signaling networks are controlled in normal healthy cells," said Klemke. "This is the first time a group ...

New technique will produce a better chromosome map

...ping fruit fly chromosomes. This new approach will enable them to construct the first accurate map of the chromosomes and tease out the secrets hidden in their stripes. Their work appears online May 6 in advance of publication in the journal Nature Methods. Fruit flies are well suited for chromosome s...

Scientists identify prion's infectious secret

...In order to glean insights into the mechanics that enable amyloid formation, Peter Tessier, a postdoctoral scientist in Lindquist’s lab, used peptide arrays—glass slides covered with thousands of tiny protein fragments. Traditionally, these arrays are used for finding binding sites within well-behaved prote...

World's leading scientists announce creation of 'Encyclopedia of Life'
