'GreeneChip' -- New diagnostic tool that rapidly and accurately identifies multiple pathogens

...amples, including tissue, blood, urine, and stool, allowing for the rapid identification of pathogens in a variety of laboratory and clinical settings. The GreeneChip system and its application in an outbreak investigation when other methods failed to implicate a microorganism in a fatal hemorrhagic fever ...

Reef warns of sea level rise

... more like water temperatures off Geraldton today, allowing the corals to flourish and reefs to form. The discovery is of particular importance as it shows that sea levels rose not only because of the expansion of the oceans due to warming, which can account for ~1/2 metre of sea level rise, but also because ...

'Erectile dysfunction' drugs heighten natural anti-cancer activity

...l that diverts the immune system away from tumors, allowing swarms of cancer-attacking T-cells to migrate to t...ng the production of nitric oxide by MDSCs thereby allowing other immune cells to "see" the cancer and attack it, says Paolo Serafini, Ph.D., a research fellow ...

Using nature's most primitive anti-viral defense system to find new approaches to cancer research

...ery one of the fruit fly's genes in cells. This is allowing him now to compare those to similar genes in human cell lines to help him understand why some cancer cells invade and spread to other parts of the body." Derek Napier, AICR's Chief Executive says the grant awarded to Dr Baum and worth £136,000 has ...

Seals protect brain, conserve oxygen by turning off shivering response on icy dives

...-conserving step of not shivering, Folkow said. By allowing body temperatures to drop, they slow metabolism and reduce oxygen demand. In addition, since shivering itself requires oxygen, there is an oxygen-conserving advantage to not shivering when diving. In addition to slowing metabolism and generally re...

T for two: Scientists show how immune system chooses best way to fight infection

... deliberately affect the type of T cells produced, allowing scientists to tackle a number of diseases which are influenced by these different types of T cells. "Our team has shown that a process known as 'trans-conditioning', which we knew to be involved in T cell development, actually has a profound influ...

Evolution and the workaround

...osomes provide “backup?copies of important genes, allowing the original copies to mutate in ways that help the cells survive stresses (such as drugs) that are meant to kill them. The observation that both yeast and cancer cells evolve chromosome duplications to work around lethal stresses suggests that...

Sandia researchers discover way to see how a drug attaches to a cell

... drug by attaching a porphyrin molecule and, after allowing the drug to bind to a cell, using light to grow a nanometer-sized particle. The nanoparticles can then be imaged with electron microscopy to reveal the location of the drug receptor molecules on the cell," Shelnutt says. "This type of nanotagging tec...

Nanoparticle assembly enters the fast lane

...ments of DNA to extend away from the gold surface, allowing for more efficient assembly. "By using properties of DNA, we can increase assembly kinetics, or speed, by relatively simple means without a lot of synthetic steps," Maye said. The research team probed the synthesized and assembled nanosystems...

Scientists find new way to manipulate DNA

...lso has implications in the field of gene therapy, allowing scientists another tool to control the length of the strands of DNA. In genome sequencing, the first step is to take the genome and break it into small pieces to reassemble it into the DNA strand that is best for further biochemistry, Solomon said. ...

Engineer ramps up protein production, develops versatile viral spheres

... carry specific proteins orstick to other capsids, allowing their assembly en masse. The tiny spheres could therefore transport targeted vaccines or medicines around the bloodstream or could be linked together in different configurations to make novel materials. Materials from assembled capsids could be light...

Spelling out cancer on the nanoscale

...itoring patients?responses during their treatment, allowing clinicians to tailor treatments to individual patients. Finally, we provide a high throughput method to identify if new cancer drugs are effective at targeting specific oncoproteins." ...

Resistance and genetic sensitivity to sleeping sickness

...and treatment operations over the past five years, allowing a substantial fall in the number of subjects infected. Sleeping sickness classically manifests itself in two forms, corresponding to two parasite subspecies. The chronic form, encountered in Central and West African countries, is caused by Trypanos...

Research suggests beta agonists may alter the immune system

...nists are very effective in opening up airways and allowing asthmatics to breathe, but their ability to address the underlying inflammation that causes most asthma has been debated for years," said Penn, an associate professor in the Department of Internal Medicine and the Center for Human Genomics. The res...

Extraordinary life found around deep-sea gas seeps

... chemosynthetic habitats occur in close proximity, allowing scientists to address key questions about the patterns of biological distribution that cannot be addressed elsewhere. The team visited eight cold seep sites on the continental slope to the east of the North Island, lying at depths of 750?050 m. ...

Advance helps explain stem cell behavior

... of steps which turn some genes on and others off, allowing a cell to become a liver cell, for instance, rather than a brain cell," said Chrissa Kioussi, an OSU assistant professor of pharmacology and co-author on the study. "We were able to use a system of microarray comparisons that monitored the expression...

Bacteria that use radiated water as food

In a way, Firmicutes serve the same function as photosynthetic organisms, such as plankton and trees at Earth's surface, that capture sunlight energy ul...
