A new mechanism of regulating RNA degradation

...on. Those observations, said Maquat, sent Kim on a hunt for what Staufen1 and Upf1 were doing. Looking at gene expression data available through the lab of Luc DesGroseillers, Ph.D. at the University of Montreal, they found that Staufen1 protein binds to numerous RNAs. Downregulating the amount of Staufe...

Grizzlies set to invade high Arctic?

...rcle. "We know grizzlies go out on the sea ice to hunt seals, but no one has ever seen one that far north," says Dr. John England a geology professor and the NSERC Northern Chair at the University of Alberta. Dr. England got his first glimpse of the surprising Melville Island grizzly bear from the air d...

Engineers improve plastic's potential for use in implants by linking it to biological material

...bacteriophage that was purchased commercially. To hunt for the plastic-preferring peptide, Sanghvi and Miller added a solution containing bacteriophages that displayed different peptides to a container with polypyrrole stuck on its inner surface. The bacteriophages that didn't wash away when exposed to c...

Cats' indifference towards sugar explained

...o wonder cats are cranky--not only do they have to hunt for their food, but they also can't enjoy a sweet dessert!" Citation: Li X, Li W, Wang H, Cao J, Maehashi K, et al. (2005) Pseudogenization of a sweet-receptor gene accounts for cats' indifference toward sugar. PLoS Genet 1(1): e3. ...

Scientists turn tobacco against cancer

...iny guided protein missiles -- that can target and hunt down cancer cells. The plants promise to provide a cheaper, faster method of producing anticancer antibodies, raising hopes that the technology can one day be used in humans. Scientists, led by Hilary Koprowski, M.D., professor of microbiology and i...

Molecular miners find pain relief drugs from the sea

...l of venom peptides. Fortunately, most cone snails hunt marine worms or other molluscs and are not harmful to humans. It may seem unusual that toxic venoms can also be a source of pain relieving medication for humans. Associate Professor Livett explains, "It appears that cone snails have adopted the gen...

Primate virus jumps species barrier to humans for first time in Asia

...d consumption, a practice in which local residents hunt monkeys for food. HIV, the virus that causes AIDS in humans, is believed to have originated as simian immunodeficiency virus (SIV), and jumped the species barrier to humans when African bushmeat hunters came into contact with blood from infected anim...

Researchers predict infinite genomes

...ely tap these known genomes in public databases to hunt for drug targets, explain ecological niches, and chart evolution. How well do these microbial genomes reflect reality? As comparative genomics itself evolves, Fraser expects TIGR to increasingly focus on pan-genomes. Many questions remain. Although...

A little telomerase isn't enough

...al Sciences. "This phenomenon could complicate the hunt for disease genes." Scientists generally figure that inherited disease accompanies an inherited mutation in one or more genes. In the case of the genetically normal offspring of two half-telomerase parents, however, the disease is still present. Th...

Newly discovered birdlike dinosaur is oldest raptor ever found in South America

...usual dentition, it may have been an adaptation to hunt small prey, such as the abundant burrowing snakes, mammals, and lizards that have been discovered alongside Buitreraptor. The remarkable dinosaur was discovered in northwestern Patagonia about 700 miles southwest of Buenos Aires. Although Buitrerapt...

Performing monkeys in Asia carry viruses that could jump species to humans

HIV, the virus that causes AIDS in humans, is believed to have originated as a primate virus and jumped the species barrier to humans when African bushmeat hunters came into contact with blood from infected animals.

Honeybee decision-making ability rivals any department committee

When 10,000 honeybees fly the coop to hunt for a new home, usually a tree cavity, they have a unique method of deciding which site is right: With great efficiency they narrow down the options and minimize their bad decisions. Their technique, says Cornell University biologist Thomas Seeley,...

Flu not the only germ threat this time of year

...ts at Rochester General Hospital, have been on the hunt for a vaccine against RSV. While they've identified several proteins on the surface of RSV, an important step toward creating a vaccine, none of the vaccines they've tested has panned out. So while people tense up about the availability of flu vacc...

UF scientists trace origin of shark's electric sense

"That doesn't mean they can only detect electric fish. They c...

Failure of 'scout cells' may lead to cancer in transplant patients

... the memory T cells, which rapidly proliferate and hunt down and kill any cells that contain growing virus or have become cancerous. If memory T cells are re-stimulated properly, they can kill the cancerous cells before PTLD develops, VanBuskirk says. But if that re-stimulation is weak or is blocked, n...

Massive duplication of genes may solve Darwin's 'abominable mystery' about flowering plants

...s and colleagues relied on a statistical filter to hunt for ancient duplications. In order to show that such an event occurred early in angiosperm history, dePamphilis and his colleagues had to compare the genomes of "basal" angiosperms--those whose ancestors diverged from the rest early in the lineage--...

Scientists describe new African monkey genus ?first in 83 years

...wned eagles and possibly leopards. But humans also hunt and kill Kipunji, and eat their meat. "Any hunting of the Kipunji or loss of its vulnerable habitat, with the latter probably increasing the frequency of the former, will further serve to threaten this important new genus," the authors conclude. ...
