Minor mutations in avian flu virus increase chances of human infection

...her, as yet "unidentified mutations" could emerge, allowing the avian virus to switch receptor specificity and make the jump to human-to-human transmission. The glycan microarray technology, which was used to identify the mutations which could enable adaptation of H5N1 into the human population in the labor...

Watching the brain switch off 'self'

...ot in enabling perceptual awareness, but rather in allowing the individual to reflect upon sensory experiences, to judge their possible significance to the self, and, not less importantly for consciousness research, to allow the individual to report about the occurrence of his or her sensory experience to the...

Rutgers researchers find fat gene

...ce of the amino acids that make up the PAP enzyme, allowing them to backtrack along the path to its origin ?the gene that coded it ?linking the enzyme to the yeast gene PAH1 that made it. Carman and his group went on to confirm the link by introducing the yeast gene into bacteria, with similar results. The r...

Botox could help target resistant tumors for treatment

...e tumors, the tumors' cellular vasculature opened, allowing for more effective destruction of previously resistant cancer cells. The study is the first to test the idea of using Botox against cancer and explores the possibility of its use as an adjuvant, assisting the effective delivery of chemotherapies and ...

Utah researchers confirm chromosome may harbor autism gene

... broken up and then bonded to the DNA on the chip, allowing researchers to compare the variations in the SNPs of the different DNA on an extremely fine scale. The chance of the same variants of SNPs in a particular region on a chromosome being passed through several generations from a founding couple to mul...

Engineered mouse mimics cognitive aspects of schizophrenia

...s. "However, rodent models have the advantage of allowing direct tests of cause-effect relationships for specific aspects of the disease, such as some of the cognitive deficits," they concluded. "We here have been able to introduce genetically a single molecular alteration in a restricted and regulated fash...

Tiny RNA molecules fine-tune the brain's synapses

...vidence that microRNAs have a role at the synapse, allowing for a new level of regulation of gene expression,"...ortant synaptic connections, forming new ones, and allowing unimportant ones to weaken. Experiments in Greenberg's lab, done in rats, showed that a microRNA ca...

Stem cell study for patients with heart attack damage seeks to regenerate heart muscle

...e cells are grown in culture to very high numbers, allowing a single donor's cells to treat thousands of patients. "The cells have the ability to expand, or multiply, under controlled conditions, and the expanded cells have the ability to develop into different types of cells in the appropriate environment. ...

Amazon rainforest greens up in the dry season

...bed forest can reach water even in the dry season, allowing the trees to flourish during the sunnier, drier part of the year. In contrast, plants in areas that have been logged or converted to other uses cannot reach deep water in the dry season and therefore either go dormant or die. Figuring out the metabo...

Ticks, flukes, and genomics: Emerging pathogens revealed

...riations of a single gene that codes for a protein allowing the bacteria to evade the immune system of the organism it has infected. This protein sits on the bacteria's outer membrane surface. When the bacteria, through tick bites, transfers to a human, say, or horse, the bacteria chooses the protein variatio...

Cheaper and simpler keyhole surgery

...n operate the camera himself (with one hand), thus allowing him to conduct the operation by himself without a (camera) assistant. A test showed that this enabled 'solo surgery' and that it even brought advantages in comparison to surgery using an assistant. The second instrument developed by Jaspers is a mec...

New University of Toronto research a 'pore' excuse for engineering

... better insulator and would take up far less room, allowing components to shrink even further. "Industry is always looking for a better insulator," Hatton says. "This is an example of how materials chemistry can provide innovative solutions to the design of novel materials." ...

Waking a sleeping virus

...emical "letters" in the DNA, docking onto them and allowing the information to be read and transformed into raw materials to make new viruses. "A good strategy in fighting viruses is to block the activation of viral genes," says Patrice Morand, a physician at the University hospital and the IVMS. "The drugs...

Clock molecule's sensitivity to lithium sheds light on bipolar disorder

... the Rev-erb protein is destroyed within the cell, allowing bmal and other clock proteins to increase. Among other actions, these clock genes cause Rev-erb to increase, which again inhibits bmal and clock. "The time it takes for that to happen determines the length of the cycle–roughly 24 hours–and keeps the ...

Anthrax inhibitor counteracts toxin, may lead to new therapeutics

...patterns on the anthrax toxin molecular structure, allowing it to bind at multiple sites and become four orders of magnitude more potent than an inhibitor that binds to a single site. "Think about how two Lego blocks snap together. A brick with four studs can interlock with a brick with four holes. These br...

Both alcoholism and chronic smoking can damage the brain's prefrontal cortex

The neural interface device between the arm and the person wearing it would be implanted in what is left of the amputated arm or sh...

Scientists a step closer to protecting world's most important crop

...own cells where they overcome the plant's defences allowing a full scale invasion by the fungus. Until now it's not been known how the fungus delivers that weaponry, but researchers from the School of Biosciences have identified a single gene that appears to be important in the process. Professor Nick Talbo...

Genome sequencing is for ecologists, too

Ahead of the game

...lopments in the social realm of modern human life, allowing routine use of distant resources and more extensive division of labor, may be better indicators of why Neanderthals disappeared than hunting practices. "The establishment of larger social networks allowed the replacement of Neanderthals in the Cauca...
