Biochemists Create Microbicidal Coating to Fight Hospital Infections
New bandages with microbicidal coating kill the most harmful bacteria on contact. The coating is washable and can also be used on hospital gowns and bed sheets, which will help reduce the risk of ... > more -
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 -
Entomologists Design Environmentally-Friendly Lawns, Golf Courses
The PGA Golf course at San Francisco's Harding Park is an environmental model, using fewer pesticides than any other PGA course in the country. Taking a cue from entomologists and other scientists, ... > more -
In Hospitals, Air Ducts with Silver-Based Coating Stay Germ-Free
Preventing hospital infections -- from such stubborn bugs as Staphylococcus aureus -- could get a little easier with a new non-toxic, silver-based material. Used in coating, it helps keep hospital ... > 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 -
Biologist, Computer Scientist Make 3D Anatomy Images Available Online
Frog biology is especially noteworthy because of the amphibians' sensitivity to pollution, which often flags previously unknown environmental problems. Science labs and classrooms around the world ... > 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
