It also describes how some conditions allow these invasive species to multiply to great numbers, the potential they pose for severe environmental damage, and how people can control or prevent their outbreaks. The authors, e...UF researchers develop tiny tool kit to study genes and unhealthy cell
...tify disease or toxins in single cells before they invade the body. On Thursday, in an achievement widely heralded as a first, researchers in France announced they had used gene therapy to cure a rare immune disorder. The UF research, which created a synthetic DNA molecule, has the potential to play a role...Do fish farms really add to the world's supply of fish?
...med Atlantic salmon often escape from net pens and invade wild populations. Today, an estimated 40 percent of all salmon caught in the North Atlantic originated in farms. More than 255,000 Atlantic salmon also have escaped into the Pacific Ocean since the early 1980s and are routinely caught by fishing ves...Three areas on chromosomes contain prostate cancer aggressive genes
... which tumors will penetrate the prostate capsule, invade the seminal vesicles, and spread to the lymph nodes. Therefore, the researchers determined, genes linked to Gleason score -- and hence tissue architecture -- could serve as molecular markers of prostate cancer aggressiveness. To investigate this po...Grasslands, deserts, mountains and fire

Scientists already know that the number of birds that survive to adulthood in grassland areas is very low and that the reason why may relat......g the theory that fungi helped plants successfully invade the land. The newly discovered fossils - microscopic spores and threads in sediments dating from 460 to 455 million years ago - push the origin of land-based fungi back some 55 to 60 million years to about the same era that green plants invaded land,...Genome sequencing sheds light on bacterium harmful to newborns

Scientists also want to understand the genetic and molecular mechanisms behind U. urealyticum's propensity to cause disease. Preliminary analyses of its genome did not fin...Global warming: lessons taught by snails and crabs
...lobal warming accelerates, plants and animals will invade cooler habitats, but many will be unable to move fast enough to avoid extinction. Whether this catastrophic scenario actually occurs is a matter of debate, but according to Somero, the ability of an organism to quickly adapt to temperature changes m...UF scientists discover novel mechanism underlying bone destruction

When osteoclasts encounter bone, they attach themselves to it, forming a connection similar to a suction cup. Using tissues from mice and cows, UF researchers di......ses vaginal yeast infections, oral thrush, and can invade tissues and produces fatal systemic infections in immunocompromised people. Under nitrogen-poor conditions, each of these fungi switch to filament form and thus become pathogenic.

When the mosquito-like Hessian fly bites into a wheat plant, it releases...Household ant invasions are determined by weather, not pesticide use, new study finds
... weather,`` says Gordon, noting that ants probably invade kitchens and dining rooms to escape searing heat or excessive dampness - and there is little we can do to stop them. ``When you don`t have ants in your house, putting out pesticides won`t make any difference,`` she concludes. ``The most reliable caus......ed no deaths and failed to cross the intestine and invade organ tissues.

Contaminants can invade the pond, daily and seasonal changes in light and temperature can make growth rates unpredictable, and the algae can shade each other after a certain point, restricting the available light.
