Solexa and collaborating scientists illuminate the small RNA component of the transcriptome

...re and a senior author on the study. "We have also released an enhanced version of our Arabidopsis MPSS website (http://mpss.udel.edu/at) to further facilitate public access and use of these data." "These experiments underscore the importance of studying the entire genome for evidence of small RNA activity. ...

Chernobyl: The true scale of the accident

...h, Environmental and Socio-Economic Impacts," just released by the Chernobyl Forum. The digest, based on a three-volume, 600-page report and incorporating the work of hundreds of scientists, economists and health experts, assesses the 20-year impact of the largest nuclear accident in history. The Forum is ma...

Plant wounds trigger bacteria

...detect specific chemical signal molecules that are released from plants or animals, and respond by initiating an attack on these host organisms," Winans said. "For example, others have shown that the bacteria that cause cholera express protein toxins only when they detect bile salts in the host's intestine. I...

GM crop that holds on to its seeds offers higher yields

...lt for farmers to rotate crops because prematurely released seeds can germinate and become weeds. Researchers, led by Lars Østergaard from the University of California at San Diego, United States, created genetically modified (GM) Indian mustard whose seedpods will not open naturally. They did this by insert...

Seeing the forest and the trees

...chanisms that absorb and store carbon. A new study released this week in the on-line edition of the journal Science suggests that tree diversity in tropical forests plays a crucial role in determining how much carbon these natural storehouses are able to hold, as well as their ability to provide other crucial...

Breath of the dragon: ERS-2 and Envisat reveal impact of economic growth on China's air quality

...here and the sum of the two is called NOX. This is released into the troposphere from power plants, heavy industry and road transport, along with biomass burning, lightning in the atmosphere and microbial activity in the soil. The emission of nitrogen oxides has increased about six-fold since pre-industrial t...

Molecular cabal contributes to stroke damage

...or is triggered by glutamate, which is known to be released during ischemia. The other component of neuronal damage that they studied is an "acid-sensing ion channel," (ASIC)--basically, a pore-like protein in the membranes of neurons. In response to the acid unleashed by ischemia, ASICs open to admit calciu...

Male elephants woo females with precise chemistry

... team showed that the enantiomers of frontalin are released in the elephants in specific ratios that depend on the animal's age and stage of its musth. They also found that alterations in those ratios elicit different responses in not only female elephants, but also other male elephants near the male emitting...

DNA self-assembly used to mass-produce patterned nanostructures

... in volume 45 of the journal Angewandte Chemie and released early online Dec. 23, 2005. It was funded by the National Science Foundation. "The process we've described creates lattices -- with patterns we specify -- at least tenfold smaller than the best lithography being used right now," LaBean said. "Plus, ...

Plants have a double line of defence

...e PEN2 enzyme, a glycosyl hydrolase. The substance released by it appears to have a fungicidal effect, which kills the pathogen. The researchers, on the other hand, observed that when PEN2 is missing, the plants become more susceptible not only to grass powdery mildew fungi but also other pests ?for example,...

Marine conservation organizations team up to conduct Indonesia coral reefs assessment

...ound the world. The complete status report will be released in early 2006. "It is extremely important to determine the status of the reefs in order to predict future food availability from the sea in this area," said Reef Check Director Gregor Hodgson, Ph.D., who will be coordinating the two-week expedition....

Software might revolutionize glucose monitoring in critically ill patients

...en shown todecrease patient survival. GRIP will be released as open sourcesoftware. Mathijs Vogelzang and colleagues from University Medical CenterGroningen in the Netherlands implemented GRIP in a 12-bed ICU, forfour months. GRIP monitors glucose levels and recommends theappropriate insulin pump rate and th...

New book highlights world's borderless conservation areas
