... circulate through the body to capture and ingest infectious agents such as bacteria. Monocytes also penetrate enflamed body tissue to help defend against infections. For this Circulation Research study, scientists tested the ......h the membrane's protein channel. This "midstream" capture had never been accomplished before. The stop-action image and knowledge of the chemical interactions between glycerol and the molecules that make up the inner surface of the membrane channel, allowed scientists to determine that glycerol is essential...USGS scientists warn: West Nile Virus is on the move

...program. The proposed system allows programmers to capture application-level semantics and invariants of interest at a high level of abstraction. Whereas specific tools have been developed by compiler writers to detect common programming errors, this system will allow programmers to formulate the correctness...UF technique detects tiny, potentially harmful airborne particles
...an larger ones because the body's natural defenses capture and expel the larger particles, while small ones lodge in the lung cavities and cause damage over time. A major component of smog, airborne particles have been tied to asthma and other diseases.

...er species of wildlife, snails and clams sometimes capture nature lover's attention in constructive ways, Thompson said. "When I bring it to the attention of property owners that they have a creature -- a snail, a crayfish or a shrimp -- living in a spring in a creek in their backyard that is found nowhe......GLING folklore that claims fish learn how to avoid capture seems to be true. A study of trout fishing published last week in New Zealand demonstrates for the first time that fish constantly exposed to anglers become "streetwise", staying out of sight and avoiding the bait. Likewise, fish caught once remember...Faster coagulation rates found in natural systems could impact industrial processing
... large aggregates of these groups collide with and capture additional particles millions of times faster than predicted by existing theories. Dr. Bruce E. Logan, the Kappe professor of environmental engineering, says, "Our results have caused us and many other scientists and engineers to think completely d...UF researchers: technique cuts pollution from burning treated wood
...n control devices in the incinerators' smokestacks capture only relatively large particles. In the heat of the incinerator, however, the arsenic vaporizes and forms extremely tiny particles -- less than 1 micron in diameter, or more than 100 times smaller than the diameter of a human hair.

This data will help scientists understand why the vast Amazon region appears to fluctuate between being a net source of carbon to the atmosphere and a net sink for a...Fragmented Forest, Fragmented Food
... Robins employ a "sit and wait" foraging tactic to capture insects and small lizards on the ground by pouncing on their prey from above. Zanette and her team used small pitfall traps to measure the amount of prey potentially available to these robins. Using PVC piping and alcohol, the researchers trapped i...The hair of the bear: USGS releases grizzly bear numbers in Glacier National Park

...plant exhausts. Tornado in a Tube In order to capture carbon dioxide from a power plant's smokestack, the greenhouse gas needs to be separated from the other flue gases. Typically, carbon dioxide makes up anywhere from 2 percent to 70 percent of the flue exhaust. To separate the gas, INEEL researchers a...Mountains of variables: The effect of landscape features on atmospheric deposition

The pollutants that are trapped by these canopies are then deposited to the forest floor, when the captured precipitation falls to the ground and when the tree loses it needles.
