New protein implicated in autism

... It is thought that genetic make-up predisposes an individual to autism, and several genes have been associated with the development of autism. Although a region of human chromosome 7 has been identified to be associated with susceptibility to autism, none of the genes in this region had been directly implicate...

Tears reveal some of their deepest secrets to researchers

...ut mass spectrometry is sensitive enough to detect individual lipid molecules, like oleamide," Nichols said. Oleamide was first identified as a lipid in the brain, where one of its roles is to induce sleep. It also has other key functions throughout the central nervous system. But the current study is the fi...

Moonlighting enzyme linked to neurodegenerative disease

...less you know someone with the condition. For that individual -- usually a child or teenager -- it is devastating. Symptoms are mild at first: muscle weakness in the arms and legs, vision impairment and slurred speech, but eventually the symptoms progress and most patients become wheelchair-bound and succumb to...

MicroRNA helps prevent tumors

Baby fish 'smell their way home'

...eady to settle," Mike says. "This evidence that individual coral reefs play such a key role in the emergence of new species is a fresh reason to take even greater care in how we look after them." ...

Ultrathin films deliver DNA as possible gene therapy tool

... dunking first in one solution, then another. The individual layers are so thin it would take roughly 10,000 of them to equal the thickness of a single sheet of paper. As it turns out, making the DNA-containing films is relatively straightforward, Lynn says, but "getting [the DNA] back out of the films is t...

Latest advances in DNA sequencing highlighted at DOE Joint Genome Institute User Meeting

...cing available to a diverse research community and individual investigators who otherwise would not have access to such a resource to advance the frontiers of their disciplines. The meeting will be held in the California Ballroom at the Walnut Creek Marriott, 2355 North Main Street. Highlights of the three-day...

Reminding doctors which antibiotics to prescribe cuts C. difficile infection rates

...colleagues investigated whether use of feedback to individual doctors about their prescribing habits can improve adherence to a narrow-spectrum antibiotic prescribing policy, thereby reducing CD cases. "National guidelines recommend narrow-spectrum antibiotic policies and suggest a variety of methods to ens...

Bird flu -- Call for antiviral drugs to be shared

...umber' (a measure of how many people an infectious individual infects on average) of the new virus that emerges. If this number is low, it will take many months before the virus spreads w orldwide and there will be plenty of time to bring an effective vaccine into use. But if the number is high then it could be...

Nanoparticles can track cells deep within living organisms

...separately by tuning the MRI scanner to each one's individual frequency, says Wickline. That makes the labeled cells potentially useful for vascular research as well. "Many kinds of cells are involved in the formation of new blood vessels," Partlow says. "Because we can create a separate MRI signature for d...

MIT: Pulsing light silences overactive neurons

...ite control over the stimulation and inhibition of individual neurons. Learning more about the neural circuits involved in epilepsy could help scientists develop devices that can predict when a seizure is about to occur, allowing treatment (either shock or light) to be administered only when necessary, Boyde...

New science of metagenomics 'will transform modern microbiology'

...Historically, microbiology focused on the study of individual species of organisms that could be grown in a laboratory and examined under a microscope, but most of the life-supporting activities of microbes are carried out by complex communities of microorganisms, and many cannot be grown in laboratory culture....

New test helps identify hepatitis C patients at high risk of developing cirrhosis

... consumption to predict such risk, but because of individual variability, these factors don't yield a very accurate prediction. A liver biopsy can indicate the amount of damage to the liver up until the time of the biopsy, but can't reveal how much future damage will occur. The new test assessed by Cheun...

UCLA: How does your brain respond when you think about gambling or taking risks?

...ences in brain activity correspond very closely to individual differences in participants' actual choices," said co-author Craig Fox, an associate professor of policy at the UCLA Anderson School of Management and an associate professor of psychology. "The people who show much more neural sensitivity to losses r...

Genes and genius: Researchers confirm association between gene and intelligence

... differences in individuals' DNA. By comparing individual differences embedded in DNA, the team zeroed in on CHRM2, the neuronal receptor gene on chromosome 7. The CHRM2 gene activates a multitude of signaling pathways in the brain involved in learning, memory and other higher brain functions. The research ...
