Researchers track how spores break out of dormant state

... of new countermeasures that identify the earliest stages of a wide range of spore mediated diseases, including botulism, gas gangrene and pulmonary anthrax,” said Alexander Malkin, senior author from LLNL’s Biosciences and Biotechnology Division. “But it’s also important to gain fundamental insights into t...

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

...rlier this year, concluded that even in the latest stages of cancer, reactivation of a previously damaged p53 pathway caused cancer tumors to stop growing and even eliminate themselves by activating an immune response in surrounding healthy cells. Most suspected that proteins would be revealed as key to th...

Researchers shed light on shrinking of chromosomes

..., “we think that the ‘super condensation’ at later stages helps to disentangle such chromosomes and acts as a back-up mechanism to rescue separation defects.” The EMBL researchers found that an enzyme called Aurora kinase is crucially involved in this process. Blocking this enzyme abolishes late condensat...

Migration alert -- How tumor cells home in on the lymphatic system

...cells migrate to the lymphatic system in the early stages of tumor metastasis. This new understanding holds significant potential for developing anti-metastasis therapies. Scientists know that tumor cells spread via the lymphatic system, but they don’t understand the details of how this deadly migration t...

454 sequencing identifies HIV drug resistance at early stage

...ucial research tool to better understand the early stages of HIV drug resistance.” It is estimated that 22 million people have died from AIDS and over 42 million people are living with HIV/AIDS worldwide. In the U.S. alone, 40,000 new infections occur each year. ...

How 'memory' T cells curb the spread of viruses throughout the body

... from the lymph node to vital organs at very early stages of the infection. “It’s like having a security check point,” said Sigal. “Also, many cancers, like viruses, must pass through lymph nodes to metastasize, so this research may help develop vaccines that prevent tumor metastases.”...

A first -- Hebrew University scientist observes brain cell development in 'real time'

... time-lapse imaging over several days at different stages of development. Mizrahi revealed that dendritic formation is highly dynamic. Moreover, once incorporated into the network, adult-born neurons in the study also remained dynamic and capable of continuous change. This method provides a mechanism fo...

'Smart' mice teach scientists about learning process, brain disorders

.... NR2B previously has been implicated in the early stages of learning. The new research showed that when Cdk5 is removed from the brain, the levels of NR2B significantly increase, and the mice are primed to learn, Dr. Bibb said. "We made the animals ‘smarter,’ but in doing so and applying this techno...

How brain pacemakers erase diseased messages

...py for other movement disorders and are at various stages of testing for the treatment of epilepsy, depression, obsessive-compulsive disorder and pain, according to Grill. The complexity of the brain -- in which nerves project in all directions and connect with one another to form multiple, looping netwo...

How the brain's backup system compensates for stroke

...that their experiments showed that "In the initial stages of adaptive compensation for neuronal interference, the adult brain exploits pre-established patterns of functional specialization. When a key node in an information-processing circuit is impaired, healthy cortical networks can flexibly reconfigure p...

pHLIP, a novel technology to locate and treat tumors

...al tests to reveal many health problems at earlier stages may be developed based on pHLIP technology? “Our discovery is an example of the reason that the NIH and DOD support basic science—we were working on the principles of membrane protein folding, and made a discovery with important medical implicatio...

First clinical trial of gene therapy for childhood blindness

...s, as we will be treating the disease in the early stages of its development." Professor Ali added: "There are many forms of retinal degeneration, meaning the use of gene therapy treatments must be individually developed then tested in a separate clinical trial specifically for that disease. However, th...

Scientists find genes involved in the battle between Hessian flies and wheat

...emical mechanisms involved when larvae - the early stages of the gnat-sized Hessian fly - try to feed on resistant wheat plants that are able to defend themselves, Shukle said. While the insects can't establish feeding sites on resistant plants, the larvae can alter the physiology and change the level of c...
