Heat-Shock Vaccine Stops Bacteria Dead
...ous agent. Unfortunately, manyinfectious organisms camouflage themselves in a sugary coat so that the T cellscan't see them. In such cases, the antibodies that are produced are of lowerquality and less effective fighters against disease. To outwit the camouflaged bacteria, scientists have begun to resort to aso...CU Research Team Unravels Mystery Of Larceny Among Tropical Ant Species
...s in Costa Rica firstconfirmed the use of chemical camouflage by E. ruidum to enter neighboring antcolonies.

... in an indirect way. The epibionts might provide a camouflage cover that could reduce overall predation on the bivalves. Jones is continuing her work by examining the wide range of Spondylus spine forms existing today to see if the different types of spines correlate with the number or type of predators prese...Traits link viruses from common cold to HIV
...me, they have evolved subtle and intricate ways to camouflage themselves or otherwise circumvent the immune defenses of their hosts. Finding common threads, says Ahlquist, means it is possible to generalize knowledge across broad classes of viruses.

...its main predators. "Youve got to have very good camouflage to trick a bird," said Sandoval, noting that birds have very good vision and are visual predators. The insect exhibits two genetically determined color patterns. The unstriped insect is more commonly found on the plant Ceanothus spinosus (commonly ...Death by color: Spiny spiders' bright stripes attract prey
... says Hauber, that sun and nearby vegetation offer camouflage for the web. "Daytime web-building and hunting, along with the web placement and orientation, is consistent with behavior that attracts prey traveling from darker areas to lighter ones," says Hauber....UK scientists crack lobster shell colour puzzle

... that might affect survival in nature, such as the camouflage coloring of a moth. This survivability variable was missing in previous studies since in them the only thing being selected for or against was the choice of habitat itself. Eventually, after months of weeding and 50 to 60 generations, Fry hopes to s...Researchers working to devise plan for Palo Alto Battlefield Restoration
...efield. The thick sections of cord grass served as camouflage for the soldiers. "According to one historical account, the soldiers would hide in it," Margo said. "It had needle-point leaves and would poke their legs. It can dominate when in a healthy stage." However, the grass can't be re-established by seed....Prescott Prize to Diane and Mark Littler
