...nts and water and leading to reduced yields. One example is red rice, a weedy form of rice that reduces the yields of cultivated rice by as much as 80 percent and contaminating harvests with its small red-coated grains. A project led by researchers at Washington University St. Louis will examine the region...

LIAI completes world's most comprehensive analysis on influenza virus data

...f a particular epitope had been used one time, for example by a single individual responding to a single virus, or 100 different times. Now, scientists can search the database and find out all existing information on their particular topic. This will enable them to avoid unnecessary repetition and make fas...

Profiling of cancer genes may lead to better and earlier detection

...e processes estrogen and tobacco carcinogens, for example may be different, said Dr. Euhus, associate professor of surgical oncology. "I was also struck that some of these processes could be detected in benign breast cells from high-risk women, more so than in lower-risk women," said Dr. Euhus, co-direct...

Development of gene therapy

...es in somatic gene therapy are on the horizon, for example in treating adenosine deaminase deficiency and chronic granulomatous disease. There are also initial indicators that point to the efficacy of gene therapy in treating chronic lymphatic leukaemia and haemophilia B. But successes in clinical testing co...

Adenine 'tails' make tailored anchors for DNA

... array--microarray "gene chips" are the best-known example of the technology. The properties of gold are well-known, so it is a practicaland convenient substrate for some sensors. One popular technique for making DNA sensors (developed at NIST) is to use DNA with a sulfur atom attached to one end, which acts...

One example is the investigation of algal growth under high light intensities with simultaneous low temperatures by scientists of the Alfred Wegener Institute, in collaboration with the Institute for Polar Ecology in Kiel. The effect of ice movement on species c...

Shotgun sequencing finds nanoorganisms

...aea in the mine slime. It was the first successful example of community genomic analysis to profile the organisms in a drop of water - scummy water. But Baker's discovery makes clear that shotgun sequencing can also pick out rare organisms too small to see easily, and too novel to be plucked out by other g...

Contrary to common wisdom, scientist discovers some mammals can smell objects under water

...ir sense of smell usually degenerates. The primary example is the cetaceans whales and dolphins many of which have lost their sense of smell." Catania devised a series of experiments to determine whether the star-nosed mole and another small, semi-aquatic mammal - the water shrew - can smell objects underw...

"This relationship is another example of technology created in CU labs moving to the marketplace, where companies like Quidel can distribute it to improve health care around the world," said David Allen, associate vice president for technology transfer in CU's Technology Transfer Office....

Too mellow for our predatory world

...mals. Over a longer evolutionary period, birds for example can lose their ability to fly. This would greatly reduce their ability to escape should new predators appear. In contrast to such "hard wired" traits, however, behavioural patterns should be significantly more flexible. In programmes introducing tame...

Self-assembling nano-ice discovered at UNL -- Structure resembles DNA

... to bond together through weak hydrogen bonds. One example of a self-assembling material is protein. Proteins can self-assemble into structures like amyloid fibrils that can build up in the brain to cause Alzheimer's disease or prions that cause mad cow disease." Another implication, Zeng said, is that the...

Geneticists discover genes that make fruit fly hybrids sterile

...ecies, the males survive. "We have found the first example of two genes that interact to cause lethality in a species hybrid," said the paper's senior author, Daniel Barbash, assistant professor in Cornell's Department of Molecular Biology and Genetics. The finding supports the Dobzhansky-Muller model, a the...

Ecologists know who eats whom and understand chemical signallingwithout them, drug discovery teams would be faced with the difficult task of looking for a needle in a haystack," STRI ...

Global warming of the future is projected by ancient carbon emissions

...dern primate ancestors. "The PETM is a stunning example of carbon dioxide-induced global warming and stands in contrast to critics who argue that the Earths temperature is insensitive to increases in carbon dioxide," said Pagani. "Not only did the Earth warm by at least 9F (5C), but it did so during a tim...

"Exploration of these minimal systems promises to lead to more exciting insights into the origins of biological complexity," she writes.

Penn researchers discover initial steps in the development of taste

...te have taste buds, but there are differences, for example humans have more (around 200) taste papillae than mice, and they are arranged in a different pattern. Future research directions will include determining whether Wnt signaling is also important for the periodic regeneration of taste buds from taste...

Study uncovers mutation responsible for Noonan Syndrome

"These results are the first example of activating mutations in an exchange factor in human disease," notes Neel, explaining that for families at risk for Noonan syndrome, the findings will aid in prenatal diagnosis and genetic counseling for the disorder. "Furthermore," Neel adds, "b...
