Iowa State scientists demonstrate first use of nanotechnology to enter plant cells

...ind of material can have a total surface area of a football field, making it possible to carry a large payload," Trewyn said. Lin’s nanoparticle has a unique "capping" strategy that seals the chemical goods inside. In previous studies, his group successfully demonstrated that the caps can be chemically act...

BMI not accurate indicator of body fat

...muscle mass, said Ode. "A previous study of NFL football players found that a large percentage of them ?around 60 percent ?were considered obese," he said. "But when you look at an athlete like that, you see that in many cases he is not obese. Many athletes have huge BMIs because of muscle mass, but in man...

ASU researchers test antibacterial effects of healing clays

... 100 square meters per gram of clay ?bigger than a football field). As a result, surface chemical reactions from these sites have an enormous impact on the geochemistry of the local environment. Williams is passionate about her subject: "Clays are as individual in character as people are in personality. Th...

Fragmentation rapidly erodes Amazonian biodiversity

... species occurring in an area the size of just two football fields. These forests are being rapidly felled and fragmented for timber operations, cattle ranches and industrial soy farms. The team, led by William Laurance of the Smithsonian Tropical Research Institute in Panama, has been studying the fates ...

Fire ant-attacking fly spreading rapidly in Texas

...rent kinds of phorid fly in an area smaller than a football field. "No single phorid species will be a magic bullet," he says. Fire ants are not typically pests or even common in South America in large part because of harassment by the phorid flies. In the presence of these flies, ants have difficulty ret...

New bird flu drug promises to beat the problem of resistance

...stance. How it works The flu virus is like a football coated with two different types of enzymes. These are proteins which carry out specific jobs for the virus. The first of these proteins, haemagglutinin (H), helps the virus to invade cells in the throat whilst the second, neuraminidase (N), allows ...

New technique puts brain-imaging research on its head

It's a scene football fans will see over and over during the bowl and NFL playoff seasons: a player, often the quarterback, being slammed to the ground and hitting the back of his head on the landing. Sure, it hurts, but what happens to the inside of the skull? Researc...

Underlying cause of massive pinyon pine die-off revealed

...by-150 meter plot (about three times the size of a football field). Temperature and precipitation data were recorded at a nearby site. In 1992, the team began tracking tree mortality. "I could see the plot from my office window," said Breshears, who used to work at LANL. When the recent drought hit, the scie...

Man-made wetland's effectiveness similar to natural marsh

...wetland in the study was roughly the size of three football fields and drained a watershed about 14 times that large. It is located in prime agricultural territory in west central Ohio ?on the shores of Great Miami River, a tributary that flows into a local lake and then on to the Ohio River, which drains to ...
