Best way to clean up toxic plumes? Give 'em a pill
...anganate to treat pollution pump it into a well in liquid form every day for a couple of months," said Frank Schwartz, a study co-author and a professor of geological sciences at Ohio State University. Like salt, potassium permanganate is granular and dissolves when it comes into contact with water. "There'...NJIT chemists pave way for cheap, usable field test for polluted, toxic, water, air, food
...er approach which can also be used for airborne or liquid pollutants as well as food contaminants uses a chemical process to create a hard gel. The gel glues together the targeted nanoparticles to form themselves into distinct micro channels. Scientists often refer to this hard gel process as a "sol-gen s...... -320 degrees Fahrenheit, the temperature of their liquid nitrogen storage bath. But when scientists thaw the cells for use in the lab, less than 1 percent awake from their frigid slumber and assume their undifferentiated state. This 'blank slate' form is characteristic of stem cells and essential for the ...A&M researcher studying genes of mosquitoes
... As mosquitoes feed, they begin excreting a clear liquid very quickly. "Diuresis, or the production of urine, is very fast. If they are still engorged, they fly very poorly and susceptible to being slapped by a human or eaten by a predator," she explained. "We want to know how the mosquit...Method produces uniform, self-assembled nanocells
... a micro version of a four-way stop. A water-based liquid containing medicines or other substances is sent toward the lipid stream from two opposing directions. Rather than mixing with the water, the lipids surround it, forming self-assembled nanocells. Controlling flow rates in the microchannels produces ...Research suggests new way to repair cartilage damage

"The solid polymer creates a scaffold of support that fills the defect, and provides the correct physical and chemical cues to enable cells that move into the defect to differentiate appropriately...UN study shows environmental consequences from ongoing boom in personal computer sales
...e Cole says that while the increased popularity of liquid crystal displays over CRTs tends to lower electricity use by computers, newer generations of microprocessors and larger monitors tend to use much more than their predecessors. Much electricity is wasted as computers also tend to be left on when not ...Capturing cell protein production in action could help fight antibiotic resistance

In each channel, heat transfer or chemical reactions happen more efficiently than they do in larger spaces, permitting better process control, shorter channel lengt...A shocking surprise: High voltage + rats = ozone, reopens power-line debate
... something called "the Taylor cones phenomenon." A liquid surface at high field strength is unstable, with spots of slightly-higher surface charge that protrude from the surface. The tips can elongate and grow so sharp that droplets and even electrons can be ejected. Since most mammals are mostly water and ...Free, public events at the 2004 AAAS Annual Meeting

After one hour the nanotube disks were washed and a microscope was used to count how many of the dyed astrocytes washed out of the suspension, which enabled the researchers to calculate how many astrocytes stuck to the nanot...Tiny heaters may pave way for easier tissue engineering, medical sensors
...emperatures below about 90 degrees Fahrenheit in a liquid environment, the polymer exists in a water-saturated, gel-like state. But when the temperature exceeds that threshold, the polymer's chemical properties change. It becomes water-repellant and allows proteins to stick to it. "When you go above thi......tanetriol.
