Materials Chemists Apply Photonic Crystals to Forensics
Photonic crystals -- materials with precise patterns of gaps that make them reflect only selected wavelengths of light -- could soon replace the traditional ink-based fingerprinting. In a new ... > more -
A Vacuum Alternative to Pesticides for Microbiology Solution
A physical chemist has developed a new technique for ridding harvested produce of insect pests and microorganisms without using pesticides such as methyl bromide. The technique, called Metabolic ... > more -
Biochemists Develop Diagnostic Tool to ID Strains Faster
Biochemists have developed a new tool that can identify a strain of influenza in hours, instead of the usual days or weeks, potentially speeding up the development of new vaccines. A sample of the ... > more -
With New Antibiotics, Pediatricians Fight Proxy War on Bugs
Strep throat has become harder to fight using penicillin or amoxicillin, but that's not because the Streptococci have developed a resistance to those drugs. Instead, more than 50 percent of children ... > more -

Biological Engineers Generate Natural Gas with Bacteria
A new kind of waste digester uses two different strains of bacteria in different tanks. This would normally take place in the same environment, but microbiologists have now separated it into two ... > more -
Are Bioluminescent Bacteria Behind Milky Seas Legend?
For centuries, sailors in the Indian Ocean have told stories of seas glowing with a dim, white light at night. Satellite images have now confirmed the appearance of what seem to be bioluminescent ... > more -
Newly Sequenced Genome Could Shed Light on Human Diseases
Molecular biologists have completely sequenced the first dog genome. Understanding how genetics plays a role in canine diseases could lead to new treatments for diseases shared by humans, such as ... > more -
Entomologists Train Insects to Act Like Sniffing Dogs
If rewarded with sugary water, wasps can be trained in minutes to follow specific smells. The olfactory sensors in their antennae can sense chemicals in the air in concentrations as tiny as a few ... > more -
Horticulture Engineers Take Years to Carefully Grow Bulbs
Of the 1,700 varieties of tulips, about 80 percent come from Holland, which exports more than $700 million's worth of tulips per year. Tulip bulbs take up to five years to fully form, and require ... > more -
Exhibit Delves into Science of Taste and Smell
An exhibit at San Francisco's Exploratorium explains the science of cooking and eating, and in particular how we taste food. Our sense of taste comes from a combination of smell receptors in the nose ... > more
