Skull study sheds light on dinosaur diversity

...tails, sauropod dinosaurs---famous as the Sinclair gasoline logo and Fred Flintstone's gravel pit tractor---are easy to recognize, in part because they all seem to look alike. The largest animals known to have walked the earth, sauropods were common in North America during the middle of the dinosaur era but...

Does manganese inhaled from the shower represent a public health threat?

...ards for manganese." The addition of manganese to gasoline as an anti-knock agent may also be a threat, the researchers said. "The manganese, as it settles from car exhaust onto streets and highways, may enter the water supply, increasing manganese levels in the water we drink and bathe in," said Spangler. ...

Blood flow in brain takes a twist, affecting views of Alzheimer's

...iar to anyone who worried over the availability of gasoline immediately after hurricane Katrina. In our bodies the process is particularly crucial in the brain, which is the body's most voracious guzzler of "fuel," with a constant need for oxygen. When part of the brain becomes more active, more blood is shun...

MIT researchers build tiny batteries with viruses

...e generally too heavy and too weak to compete with gasoline as an energy source. Still, battery technology is gradually being improved and may someday even become competitive as the price of oil escalates. "The nanoscale materials we've made supply two to three times the electrical energy for their mass or v...

Scientific issues associated with carbon-neutral energy sources such as cellulosic ethanol

...domestically produced biofuels. Displacing use of gasoline with biofuels, such as cellulosic ethanol, will dramatically reduce emissions of stored carbon dioxide into the atmosphere, Somerville noted. This past year, Somerville has been participating in workshops organized by the U.S. Department of Energy ...

The first tree genome is published: Poplar holds promise as renewable bioenergy resource

...ping practical, biologically-based substitutes for gasoline and other fossil fuels." "Biofuels are not only attractive for their potential to cut reliance on oil imports but also their reduced environmental impact," said Dr. Gerald A. Tuskan, ORNL and DOE JGI researcher and lead author of the SCIENCE study....

Engineered yeast speeds ethanol production

...ply. Currently used as a fuel additive to improve gasoline combustibility, ethanol is often touted as a potential solution to the growing oil-driven energy crisis. But there are significant obstacles to producing ethanol. One is that high ethanol levels are toxic to the yeast that ferments corn and other pla...

Lead with a poisonous electron shield

...d containers. Though the introduction of lead-free gasoline has reduced damage to the environment, the annual production of lead continues to increase worldwide because lead is still used in batteries, glass, and electronic components. However, there has thus far been little research into what, at a molecular...

New biofuels process promises to meet all US transportation needs

...t making the concept economically competitive with gasoline and diesel fuel would require research in two areas: finding ways to produce cheap hydrogen from carbon-free sources and developing a new type of gasifier needed for the process. "Having said that, this is the first concept for creating a sustaina...

Fuel from fiber -- Pretreatment can put corn stalks, trees in your car's tank

.... "In time, we can expect to completely replace gasoline and diesel with cellulose-derived biofuels that are cheaper, better for the environment and much better for national security than petroleum-derived fuels," Dale said....
