8 plants from South Africa may hold potential for treating high blood pressure

...t three separate determinations were conducted for each test compound. A tannin test was only conducted on those plant extracts that exhibited over 50 percent ACE inhibition in the initial analysis. The data was subjected to GraphPad Instat (GraphPad Software Inc, San Diego, CA, USA). All values were ex...

Brain's white matter -- More 'talkative' than once thought

...re Neuroscience, shows that brain cells “talk?with each other in more ways than previously thought. “We were surprised to see these nerve axons talking to other cells in the white matter,?says Dwight Bergles, Ph.D., an associate professor of neuroscience at Hopkins. The discovery focuses on oligode...

An ancient bathtub ring of mammoth fossils

...g to tease out as much information as we can about each and every mammoth find in the mid-Columbia basin, so that we can better understand the impacts that Ice Age floods may have had on the mammoths and other creatures, and in turn learn more about the history of Ice Age flooding."

Scientists: As rainfall changes, tropical plants may acclimate

...the soil and leaf samples of four plant species at each site. They learned that drier soils contained more nitrogen in the form of nitrate, while wetter soils contained more nitrogen in the form of ammonia. Isotopic analysis of the plants revealed that they switched from nitrate to ammonia "abruptly, and ...

...hold them in place. The tiny openings in the mesh, each about 250 microns in diameter, would allow blood to pass through to nourish the cells and disperse helpful proteins. But the openings are too small to allow the microcapsules to escape. In lab tests using latex tubing to represent a vein, the stu...

While polyps provide the framework, coral's vivid hues come from symbiotic single-celled algae that live in the polyps. The algae supply much of the food coral need to survive.

The longest carbon nanotubes you've ever seen

...While still slightly less than 2 centimeters long, each nanotube is 900,000 times longer than its diameter. The fibers--which have the potential to be longer, stronger and better conductors of electricity than copper and many other materials--could ultimately find use in smart fabrics, sensors and a host...

"The next step is to figure out how to get them to stay in care," said Giordano. He plans to look for ways to in...

Magnetic computer sensors may help study biomolecules

...ns. NIST researchers made an array of spin valves, each about one by four micrometers in size, patterned on a 200-nanometer-thick silicon nitride membrane in fluid. When the spin valves are turned on, a local magnetic field is created that is strongest near the ends of the magnetic stack below the membran...

Confirmed -- deforestation plays critical climate change role

...eforestation releases 1.5 billion tonnes of carbon each year into the atmosphere. "Deforestation in the tropics accounts for nearly 20 per cent of carbon emissions due to human activities," Dr Canadell says. "This will release an estimated 87 to 130 billion tonnes of carbon by 2100, which is greater tha...

DOE JGI sets 'gold standard' for metagenomic data analysis
