Hijacking bacteria's natural defences to trap and reveal pathogens
Bad bacteria could soon have no place left to hide, thanks to new materials that turn the cell's own defenses against them. Scientists at The University of Nottingham and GSK Consumer Healthcare have developed ...
How a plant beckons the bacteria that will do it harm
A common plant puts out a welcome mat to bacteria seeking to invade, and scientists have discovered the mat's molecular mix.
In-package plasma process quickly, effectively kills bacteria
(Phys.org) —Exposing packaged liquids, fruits and vegetables to an electrical field for just minutes might eliminate all traces of foodborne pathogens on those foods, according to a Purdue University study.
Scientists uncover mechanism for natural plant immunity
Scientists in Norwich and China have, for the first time, uncovered exactly how an immune receptor mediating plants' natural immunity to bacteria works.
Why a bacterium got its curve—and why biologists should know
Drawing from his engineering background, Princeton University researcher Alexandre Persat had a notion as to why the bacteria Caulobacter crescentus are curved—a hunch that now could lead to a new way of ...
Proteins barge in to turn off unneeded genes
(Phys.org)—The sorcerer's apprentice started a water-carrying system, but couldn't stop it, and soon he was up to his neck in water, and trouble. Living cells have a better design: When they activate a ...
Viruses help scientists battle pathogenic bacteria and improve water supply
(Phys.org)—Infectious bacteria received a taste of their own medicine from University of Missouri researchers who used viruses to infect and kill colonies of Pseudomonas aeruginosa, common disease-causing bacteria. The vi ...
Strategy discovered to activate genes that suppress tumors and inhibit cancer
(Medical Xpress) -- A team of scientists has developed a promising new strategy for "reactivating" genes that cause cancer tumors to shrink and die. The researchers hope that their discovery will aid in the ...
Researchers use SSRL to decipher structural details of deadly enzyme
(Phys.org)—A small team of researchers has used the brilliant X-rays of the Stanford Synchrotron Radiation Laboratory to pin down the crystalline structure of an enzyme complex that scientists had spent ...
50-year cholera mystery solved: Answers may help clear the way for a new class of antibiotics
For 50 years scientists have been unsure how the bacteria that gives humans cholera manages to resist one of our basic innate immune responses. That mystery has now been solved, thanks to research from biologists at The University ...
Simple device can ensure food gets to the store bacteria free
A Purdue University researcher has found a way to eliminate bacteria in packaged foods such as spinach and tomatoes, a process that could eliminate worries concerning some food-borne illnesses.
Even bacteria use social networks
The next time your Facebook stream is filled with cat videos, think about Myxococcus xanthus. The single-cell soil bacterium also uses a social network. But forget silly distractions. M. xanthus relies on ...
Harnessing plant-invading fungi for fuel
(Phys.org)—As gas prices rise around the world, researchers are seeking a potential solution from endophytic fungi—fungi that live inside plants.
