These include cancers arising in organs of the gastrointestinal tract, such as the stomach, pancreas, esophagus and biliary tract. According to Beachy, since all these ca...

Songbirds escaped from Australasia, conquered rest of world

...a, as previously thought. Instead, their ancestors escaped from a relatively small area--Australasia (Australia, New Zealand and nearby islands) and New Guinea--about 45 million years ago and went on to populate every other continent save Antarctica. The study, led by Keith Barker of the University of Minnes...

Microscopy scans show how brain cells process energy

...." If that seems like a fine point, it is one that escaped scientists who developed PET and fMRI (functional magnetic resonance imaging) scanning technologies, as well as the medical personnel who use those diagnostic tools everyday without knowing exactly what the images represent.

Researchers find no safe place to sit in California tick-infested forest

... roller to pick up ticks that might otherwise have escaped their attention. All told, they found a total of 86 nymphal ticks on their bodies during the field trials.

Studies offer new insight into HIV vaccine development

...o weakened the virus. To model the transmission of escaped viruses between people, the team inoculated monkeys with the mutant virus strain. They discovered that most of the escape mutations were lost as the virus grew in the monkeys, often restoring original sequences that killer cells could recognize. ...

MBL scientists confirm evolutionary exception

...imals have evolved without sexual reproduction and escaped extinction. "We can now use belloid rotifers to test the theories about why sex is important," says Mark Welch. "Any good theory will now have to account for why the bdelloids are an exception." Note to Editors: The paper entitled "Cytogenetic evid...

RNA lariat may tie up loose ends to decades-old mystery of retrovirus life cycle

...icate. He surmises that the lariat structure had escaped detection for so long because of its transient nature. As the RNA is being transcribed into DNA, another part of the viral machinery "chews up" and destroys the RNA. Yeast cells are common laboratory models because they are structurally similar to h...

US develops lethal new viruses

...use or rabbit populations around the world if they escaped from a lab. However, this discovery also means some bioterrorists might be more tempted to use the same trick to modify a pox virus that infects humans. Such a disease, like anthrax, would infect only those directly exposed to it. It would not sprea...

Wolves are rebalancing Yellowstone ecosystem

... "The last period when aspen trees in Yellowstone escaped the effects of elk browsing to generate trees into the forest overstory was the 1920s," Ripple said, "which is also when wolves were removed from the park." But in at least one place - America's first national park - there is now cause for hope. Whi...

Scientists determine identity, cell locale and quantity of nearly all proteins in an organism

...y technical reasons, some of the proteins may have escaped successful tagging. Nonetheless, the project was easily thorough enough to net some striking findings. For example, the research revealed that of the 4,200 yeast proteins scrutinized, a full 527 of them -- or about one in eight - work in the energy-c...

Researchers urge caution over using ginseng in early pregnancy

Ginsenoside Rb1 is only one of the ginsenosides in commercially available ginseng. More than 20 had been identified and previous studies had shown that di...

Salmon farms pose significant threat to salmon fisheries in the Pacific Northwest, researchers find

...wrote, noting that well over a million salmon have escaped from farms in Washington and British Columbia during the past decade.

For them, the arrival of the Spanish virus would be a disaster, allowing rabbit populations to boom. If the potential for international conflict is obvious, the means of preventing it is not. None of...

Historical coral reef declines featured in this week's Science

Parasites prevent ants from protecting coffee plants

...ith phorids, and some caterpillars on those plants escaped ant attacks altogether. The system illustrates what ecologists call a trophic cascade, in which changes higher up in the food chain cascade or trickle down to affect organisms at lower levels. "Having phorids in the system cascades down to affect Azt...

Researchers discover strategy that shields HIV from destruction

The new data suggest a more active role for HIV-1-neutralizing antibodies in virus containment and an unexpected m...
