Ancient genes used to produce salt-tolerant wheat

... "Bread wheat is quite tolerant to salt, but we think it too can be improved. Our aim is to eventually produce wheats able, like barley, to grow in highly saline soils," Dr Munns says. Over six per cent of the world's arable land is affected by salinity. Salt tolerant crops can provide farmers with i...

Glucose triggers brain cell death in rats after hypoglycemic coma

...ly dependent upon the amount of glucose given. "We think that this stems from a known link between glucose and NADPH oxidase," Swanson says. "Glucose is a precursor for NADPH, which in turn is used by NADPH oxidase in generating oxidative stress." Swanson explains that the results have implications for...

Study shows isolation of stem cells may lead to a treatment for hearing loss

...ansition from stem cells to hair cells, and we can think of developing strategies for cell replacement, i.e. transplanting these cochlear stem cells into the adult cochlea to affect hair cell replacement in the mouse, by extension, in humans?remarked Dr. Alagramam. In this paper, Drs. Miller and Alagram...

Cambodian vulture nests offer hope for species

...cal people benefit from conservation activities. I think we have a good chance of making it work here if we can find the support." The slender-billed vulture is one of several vulture species in Asia that have been driven to the brink of extinction across its entire range due to Diclofenac, an anti-infl...

Enhancing activity of marijuana-like chemicals in brain helps treat

...s a really important difference, and it is why we think our manipulation of the chemicals is really different from smoking marijuana." The researchers began their study by focusing on a region of the brain known as the striatum. They were interested in that region because it has been implicated in a...

Smithsonian scientists discover new marine species in eastern Pacific

...found in the Indo-Pacific, half a world away. "To think that the larvae of Hymenocera picta, a little shrimp we collected on Isla Seca, can survive a journey of more than 3,000 miles from the Indo-Pacific to the coast of Panama is mind blowing!" said Darryl Felder from the University of Louisiana. Felder...

Scientists uncover link between ocean's chemical processes and microscopic floating plants

Combining future experimental and modeling efforts will lead to a better understanding of the feedba...

Bacterial walls come tumbling down

"We have a totally new understanding of how the enzyme works and how a very good animal antibiotic inhibits the en...

How trees manage water in arid environments

...uck by a major difference: people in Indiana don't think about water every day the way people in Arizona do. The difference shows up in many ways. In Arizona, Brown said, if you drop a piece of ice on the kitchen floor and ignore it, in a few minutes it will be gone -- melted and then evaporated. In Ind...

Hybrid molecule causes cancer cells to self-destruct

"Our insight was to select the sugar partner to serve not just as a passive carrier but as additional ammunitio...

Misclassified for centuries, medicinal leeches found to be 3 distinct species

It is possible that within three to five years we'll be finished the animal trials and be looking at clinical trials in humans."

The researchers also discovered that, while XptA1 was highly selective in that it b...
