Researchers are using nanotechnology to build microscopic silicon devices with features comparable in size to DNA, proteins and other biological molecules – to count molecules, analyze them, separate them, perhaps even work with them one at a time.
When it comes to calming "nuisance-barking" dogs, a spritz of fragrance under the chin is more effective than electric shock, a test by the Animal Behavior Clinic at Cornell's College of Veterinary Medicine has found.
An increasingly popular commercial corn, genetically engineered to produce a bacterial toxin to protect against corn pests, has an unwanted side effect: Its pollen kills monarch butterfly larvae in laboratory tests, according to a report by Cornell University researchers.

As unpleasant as it is, the nausea and vomiting of "morning sickness" experienced by two-thirds of pregnant women is Mother Nature's way of protecting mothers and fetuses from food-borne illness and also shielding the fetus from chemicals that can deform fetal organs at the most critical time in development.
