Enlisting genomics to understand flu evolution

...enough samples from around the world," he adds, to find the benign virus strain that will become next season's scourge. The more genomes scientists collect--and the more refined the tools of genomics become--the greater the chances of developing more effective vaccines. Citation: Holmes EC, Ghedin E, Mil...

Achilles heel of the herpes virus possibly found

... away from being able to use this new knowledge to find effective drug candidates, this is a very exciting... herpes virus. They searched the genome library to find genes essential to HSV infection, isolated the B5-coding sequence, and figured out how to get pig ce...

Researchers use 3-D imaging system to unveil swimming behavior of microscopic plankton

...r in the Marine Physical Laboratory at Scripps. "I find it fascinating and remarkable that we can capture the reflection of such tiny creatures in three dimensions from two meters away." The divers frequented the underwater setup to sample the animals, reorient the transducer and measure the vertical cur...

Biologists determine genetic blueprint of social amoeba

...ch we will relate the gene function information we find to humans," Kuspa says. "It makes Dictyostelium a better model for looking for targets against which drugs can act." Key collaborators in the project at Baylor included Richard Gibbs and George Weinstock, co-directors of Baylor's Human Genome Sequen...

Newly discovered genetic disease sheds light on body's water balance

...on." First, Gitelman and his colleagues worked to find an innovative treatment for the two young patients. "When adults retain too much water we can treat them by restricting fluid intake," he said. "We can't do that with infants -- almost all of their nutrition comes in liquid form." The physicians wer...

Researchers develop new method for facile identification of proteins in bacterial cells

...d resources on eliminating the background noise to find the signal, our method increases the signal upfront so that it stands out above the background noise. By forcing an up-regulation of enzyme expression in the bacterium of interest, our target can be identified amidst all of the other cell components,...

Novel compounds show promise as safer, more potent insecticides

...ath risks and there’s a growing effort underway to find safer replacements. Targeting the ryanodine receptor may offer a promising alternative, researchers say. Ryanodine, a natural alkaloid discovered years ago in a species of tropical plant, has been used to study muscle physiology in a wide variety of...

A virus-like hitchhiker may trigger bacterial meningitis

...- known as 'hyperinvasive' strains -- occasionally find their way into the blood stream and then into the brain, where they trigger a potentially fatal immune response (meningitis). Tinsley and colleagues have now discovered that many hyperinvasive stains of N. meningitidis contain a bacteriophage (a vir...

Scientists turn tobacco against cancer

Tufts researchers shine light on firefly mysteries

...r words, are some male fireflies lying in order to find romance? "If female mate choice is adaptive, we would expect that the more attractive males would provide females with greater material benefits and/or genetic benefits," said Sara Lewis, associate professor of biology in the School of Arts & Sc...

Fluorescing lab worms signal longer life spans

... "By finding them, we should ultimately be able to find what makes an animal robust to many different insults." Johnson authored a milestone paper in 1988 showing that mutating a single gene in roundworms could double their life span -- the first evidence that the lifespan of an animal could be increased...
