Researchers develop flood-tolerant California rice

... like to develop rice that is both submergence and salt tolerant," she said, "given that many flood-prone areas are a mixture of fresh and salt water." Besides Bailey-Serres, Takeshi Fukao of UCR; and Kenong Xu and Pamela C. Ronald of UC Davi...

Tiny airborne particles are a major cause of climate change

... presence of small amounts of aerosols such as sea salt and desert dust. These tiny particles serve as the seeds around which water vapor in the air condenses, forming tiny water droplets that rise as they release heat. As the small droplets rise, they collide and merge with larger droplets. When the drop...

How healthy is that marsh? Biologists count parasites

Is that salt marsh healthy? To answer this, Sea Grant biologist... to collect California horn snails from 30 coastal salt marshes between Marin County and Imperial Beach at the U.S.-Mexico border. "The horn snail is a mob...

Invasive species alter habitat to their benefit

... activity, such as the use of fertilizers and road salt and the suppression of natural wildfires, also may result in environmental changes that affect species diversity. "My question was, are humans causing the changes, or are the invaders?" Farrer said. "Finding the answer has practical implications: i...

UCI scientists find chlorine may contribute to ozone formation

... salts are naturally present in coastal air in sea salt aerosols, which are swept from the ocean into the air by the wind. Chlorine gas also is used to treat water in swimming pools, cooling towers and municipal water supplies. Chlorine atoms react rapidly with hydrocarbons and nitrogen oxides from automo...

Tastes great! Study shows brain's response to pleasing -- and changing -- tastes

... cells in that area while the rats received water, salt water and sugar water directly into their mouths. ...ated with drugs that greatly reduced their bodies' salt levels. At first, the rats all behaved negatively after tasting a strong salt-water solution, com...

Microcapsules like it hot and salty

Sunflower speciation highlights roles for transposable elements in evolution

...desert environments, while the third is adapted to salt marshes. Both hybridization and abiotic stress have been implicated as natural agents of activation and proliferation of transposable elements. ...

Climate change has surprising effect on endangered naked carp

... organ which excreted water at a greater rate than salt in river-water, to one which conserved water relative to salt in lake-water," explain the researchers. Long-term lake-water-acclimated fish also adjust by acti...

Pleasure and pain: Study shows brain's 'pleasure chemical' is involved in response to pain too

...heir jaw muscles were being injected with harmless salt water in order to cause pain. The questionnaires measure pain and emotion in a standardized way, so that ratings can be compared over time. None of the participants had a history of medical or psychiatric illness, nor of drug addiction or dependence....

Special chip provides better picture of salmon health

...ation, which enable them to live in both fresh and salt water. Assessing their health and performance is very difficult as conventional measures used in other animals, such as temperature, blood protein levels and general demeanour, are not relevant or are difficult to assess in fish. Farmers and conse...

Sandia researchers discover way to see how a drug attaches to a cell

... reducing or increasing the amount of the platinum salt placed into the solution. Shelnutt sees many potential applications for this process, including "nanotagging" biological structures such as drug molecules. "This would involve labeling the drug by attaching a porphyrin molecule and, after allowin...

Like salty food? Chances are you had low blood sodium when you were born

...s were tested for their preferred concentration of salt in soup and sugar in tea, followed by orally administered spray tests involving table salt and table sugar. Between the tests the children and escorting parent(s) were interviewed about dieta...

Eating less salt could prevent cardiovascular disease

People who significantly cut back on the amount of salt in their diet could reduce their chances of develo.... Researchers in Boston also found a reduction in salt intake could lower the risk of death from cardiovascular disease by up to a fifth. Cardiovascul...

Shedding new light on proteorhodopsin

...ein, bacteriorhodopsin, that's used by bacteria in salt ponds to supplement respiration. However, in experiments in which marine bacteria endowed with proteorhodopsin were exposed to light, there was no response. This begged the question: What does proteorhodopsin actually do? A recent study out of th...

Rapid, Low-Cost DNA Testing

...s takes 10 seconds and costs $0.02. Step 3. Add salt to the solution. This takes 10 seconds and costs $0.01. Step 4. Measure photoluminescence. This takes 1 minute. It's as simple as that, yet nobody's ever done it before. The method is so new that the University of Rochester filed patents for it...

Hybrid molecule causes cancer cells to self-destruct

...e other sugar-butyrate combinations and a butyrate salt compound with no sugar attached. The four other formulas and the butyrate-ManNAc hybrid were each added to lab dishes containing cancer cells. After three to five days, cancer growth had slowed in all of the dishes. After 15 days, however, cancer gro...

...tivity and urate in the adipose tissue. Urate is a salt derived from uric acid. "Our results identify XOR as a potential therapeutic target for metabolic abnormalities beyond hyperuricemia," the researchers said. "To our knowledge, there have not been studies designed to explore the effects of XOR i...
