Genomic Analysis Uncovers New Targets for HIV Vaccine

...a series of future genome-wide studies to pinpoint additional targets for HIV vaccines. In the new analysis, pat...iscover even more polymorphisms that could provide additional clues how some patients are better able to control the virus than others," Goldstein. "This should u...

Scratch no more: Gene for itch sensation discovered

...t mice still scratched a little suggests there are additional itch receptors," Chen says. "We know of some proteins that are similar to GRPR, so now we're trying to determine if there is functional redundancy in the itching pathway." GRPR knockout mice had normal reactions to painful stimuli, indicating that p...

Brain inflammation may be friend, not foe, for Alzheimer's patients

...cted by the disease – and followed the mice for an additional month, watching for effects in the brain regions that were awash in higher-than-normal levels of IL-1beta. It’s the first use of an organism where scientists can boost IL-1beta in select areas and then watch what happens as the process unfolds. Th...

Research team identifies new Alzheimer's gene

... or genetic variations to characterize and confirm additional LOAD susceptibility genes. The search revealed GAB2. Based on the genetics of this and other neuroscientific findings, researchers suggest the healthy form of the GAB2 gene may protect brain cells from developing tangles, one of the hallmarks of A...

Dirty snow may warm Arctic as much as greenhouse gases

...es absorb sunlight more rapidly than snow, causing additional warming. This cycle causes temperatures in the polar regions to rise as much as 3 degrees Celsius during some seasons, the scientists say. “Once the snow is gone, the soot that caused the snow to melt continues to have an effect because the ground...

Salty oceans provide early warning for climate change

...of water becomes salty enough it sinks, drawing in additional water from surrounding areas, and initiates an ocean circulation loop called thermohaline overturning. The scientists discovered that a build up of salt in the waters off the coast of South Africa could help to speed up ocean circulation in the No...

Stroke study sheds light on left-right brain divide

... this research highlights, for the first time, the additional challenges that people with right frontal-lobe damage might face in everyday life.’ 23 people, each with frontal lobe damage, performed a ‘rule-switching’ task which involved learning rules linking the colour of a symbol on a computer screen with ...

Now, self-healing materials can mimic human skin, healing again and again

...ith catalyst particles. If the crack reopens under additional stress, the healing cycle is repeated. “Ultimately, the ability to achieve further healing events is controlled by the availability of active catalyst,” said Kathleen S. Toohey, a U. of I. graduate student and lead author of the paper. “While we ca...

ASU research shows connection between testosterone, dietary antioxidants and bird coloration

...inked to testosterone levels. Birds who were given additional testosterone depleted their carotenoid levels and became healthier, as if they were combating testosterone directly with antioxidants. “These findings show that there are nutrient specific mechanisms by which animals can avoid the immune costs of ...

Plastic that grows on trees

...onvert the sugars to HMF. Ionic liquids provide an additional benefit: It is reusable, thus produces none of the wastewater in other methods that convert fructose to HMF. Metal chlorides belong to a class of ionic-liquid-soluble materials called halides, which “in general work well for converting fructose to...

454 sequencing identifies HIV drug resistance at early stage

...e testing methods that are used in the clinic. The additional low abundant resistant variants detected by Ultra Deep sequencing were found to be extremely important as it enabled the prediction of early antiretroviral treatment failure with strong statistical significance. “Current genotypic resistance technol...

Gene responsible for common hearing loss identified for first time

...option is an operation. However, there is often an additional component of hearing loss which can’t be restored by surgery. As the gene involved is a growth factor, and the disease manifests itself by the abnormal growth of bone in the middle ear, it may have a large potential for therapy”, she said. Improved u...

Weizmann Institute scientists develop a general 'control switch' for protein activity

... and in the future the new technique may find many additional uses. The switch has a genetic component and a chemical component: Using genetic engineering, the scientists insert a short segment of amino acids into the amino acid sequence making up the protein. This segment is capable of binding strongly and...
