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.
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.
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 ...
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.
A zap of cold plasma reduces harmful bacteria on raw chicken
A new study by food safety researchers at Drexel University demonstrates that plasma can be an effective method for killing pathogens on uncooked poultry. The proof-of-concept study was published in the January issue of the ...
