Researchers Apply DNA Biology to Vaccination Technique
Spraying viral genes directly through the skin is a new technique that turns infinitesimal amounts of DNA into an effective vaccine. If approved for use in humans, the new procedure could save lives ... > more -
Microbiologists Find Soap and Water Best for Washing Hands, Removing Germs
Microbiologists tested 14 hand-hygiene agents -- everything from soap and alcohol rubs to plain old tap water -- against hardy bacteria and viruses applied to the hands of 62 volunteers. The study ... > more -
Chemists Steal Engineering Tricks from Sponges
Sponges are the homes of colonies of tiny marine animals, and wonders of miniaturized engineering. They employ complex structural arrangements, the strongest glasses known to man, and even ... > more -
Plant Scientists Graft Apple Trees to Select Disease-Resistant Traits
Grafting -- an ancient way of cloning plants -- enables plant scientists to create new varieties of apples. The selected genetic traits allow trees to resist pests with less pesticides, and to make ... > more -
Insect Ecologist Spearheads Creation of Oases for Endangered Butterflies
Waystations for monarch butterflies are sprouting up around the country. With milkweed plants and flowers such as zinnias that produce lots of nectar, these gardens will provide oases for the ... > more -
Mechanical Engineers Have New Bug-Inspired Robot That Senses Its Way With Flexible Antenna
Researchers have developed a flexible, sensor-laden artificial antenna to help a robotic "bug" move and navigate just like the common cockroach. The bug can curry along walls, turn corners, avoid ... > more -
Chemist's Glue Borrows Unique Amino Acid from Mollusk
Chemists combined an exotic form of an amino acid -- used by mussels to stick to rocks -- with soy flour to make a new, high-strength adhesive. The new glue helps in manufacturing natural-looking ... > more -
Materials Engineers Turn to Ferocious Fish for Nonstick Ship Coating
Researchers are using shark skin as a model for creating new coatings that prevent adhesion of algae and barnacles to boats. The new coating is modeled after sharks' placoid scales, which have a ... > more
