...dica and Japonica genes ). This would further help discovering distribution of the hybrid genes in F1 and the changes of physiological traits, thus revealing the source of the hybridization advantage in hybrid rice. ...

Researchers identify target for cancer drugs

...ience, researchers from the Sabatini lab report on discovering an important missing piece of the activation process. This missing component, a molecule called mTOR, is a protein that influences a cell's ability to expand in size. mTOR has been widely studied as the target for the immunosuppressant drug rapamyci...

New studies suggest airborne SARS transmission is possible

...ng Kong, emphasized the scientific significance of discovering SARS coronavirus in the air in a patient's room. "Although the possibility of airborne dissemination of SARS coronavirus has been controversial," said Dr. Tong, "this important work shows beyond doubt that SARS coronavirus aerosol generation can occu...

New tumor-suppressor gene discovered

...e. Lai's team also tackled the tough challenge of discovering how the mats gene is able to suppress the growth of tumors. "We did not find many clues when we compared the sequence of the mats gene with the sequence of other genes in the public databases," Lai says. "But we did find a counterpart to the mats gen...

Advancements In Genomics Foster Deep Sea Discoveries

...ssure. Scientists say precious information lies in discovering how organisms have adapted and evolved to such conditions. Bartlett and his colleagues probed the genetic makeup of Photobacterium profundum, a bacterium that copes with pressures of 4,000 pounds per square inch. The researchers grow the microbes in...

Successful Test Of Single Molecule Switch Opens The Door To Biomolecular Electronics

...developed into a working electrical switch, but in discovering some critical design parameters that should make possible successful research in designing molecular devices. “We have a working rational roadmap now for how to do this, and we’re already hard at work applying it to a wide variety of potentially exc...

Whole-body MRI Takes Less Than 20 Min To Scan A Patient's Entire Body For Cancer Spread To Bone

...found that whole-body MRI is fast and accurate for discovering bone metastases. However, they discovered that whole-body FDG-PET is superior to whole-body MRI in for staging lymph nodes, soft-tissue tumors and metastasis in the internal organs. For that study, the researchers scanned 120 patients using both who...

Scientists discover odd-ball rodent

...species. "Skeptics might say that if we are still discovering such amazing new animals, why are people worried about wildlife loss; but of course it is an indication of how little we know, and a window onto what we could be losing without ever knowing," said Dr. Timmins. ...

UCLA cancer researchers shake loose hidden biomarker

...lieved the opposite was true, Rajasekaran said. So discovering the mechanism of moving the PSMA to a more treatment accessible location on the cell could have ramifications for treating the sickest patients, those in whom the cancer has spread. "The ability to reverse the polarity of PSMA from apical to the bas...

Discovery of an American salamander where it shouldn't be: Korea

More animals join the learning circle

...ansmission can instead be explained by individuals discovering the skill on their own rather than following another's lead. But because the gull-baiting behaviour is so unusual, "it would be hard to argue that it is individual learning", says ethologist Janet Mann of Georgetown University in Washington DC, one o...

Evolution of life on Earth may hold key to finding life in outer space

...at the University of Illinois, Fox was involved in discovering the existence of a third kingdom of life now known as the Archaea. This discovery is regarded as one of the major breakthroughs in biology in the last 100 years. A combined UH/NASA night with two free screenings of "Fantasy Worlds" for UH students, ...

UCLA researchers identify key enzyme linked to childhood blindness

...It's like searching the world for a treasure, then discovering it in your own back yard." Leber congenital amaurosis is an inherited disease that is believed to cause up to 20 percent of all cases of childhood blindness. It is caused by mutations in several different genes including RPE65. An important characte...

Smoking damages key regulatory enzyme in the lung

...MAO A subtype in nine smokers and nine nonsmokers, discovering that MAO A was fairly well "intact" in all of the peripheral organs except in smokers' lungs, said Fowler. Smokers had MAO A levels that were 50 percent lower than in nonsmokers, she said, noting that a prior study had also shown a significant reduct...

Kenya halts first field trials of GM maize

Wilson Songa, Kenya's agriculture secretary and chair of the National Biosafety Committee, said this could compromise the validity...

Wright bros. upstaged! Dinos invented biplanes

...'t interfere with flight. Another key element to discovering Microraptor's flight secrets was setting some realistic limitations on how the dinosaur could move its hindlimbs ? something that was initially overlooked by Chinese researchers who found the fossil. Chatterjee and Templin studied its anatomy and fou...

Delaware scientists make significant advance in study of small RNAs

...ce in the study of small ribonucleic acids (RNAs), discovering 10 times more small RNAs in the plant Arabidopsis than previously had been identified. The advance is reported in the Sept. 2 issue of Science magazine. The research was conducted over the course of the last year and a half by teams from the laborat...

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

...d by Apestegua helped fill in missing bones. Since discovering the first two Buitreraptor fossils, the scientists have discovered at least two more in the same area during fieldwork conducted in January 2005. "Although Buitreraptor is a recent discovery, we already have a very good sample of this remarkable din...
