Certain Dry Foods Are Good Past Their Best-before Date, Food Scientists Say
Some low-moisture foods such as dried apples can be safe to eat even years after their expiration date, if properly stored, food chemists say. They verified this in a tasting experiment of ... > more -
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 -
Sniffing Dog Provides Cost-Effective Contamination Detection
America's only dog that's trained to sniff mercury is able to detect as little as a half-gram, and is faster and cheaper than traditional lab analysis. Dogs' olfactory membranes are larger and 44 ... > more -
Food Chemists Find that Milk Pushes Air to Break Crystallized Sugar
Food scientists have discovered why Rice Krispies make their characteristic sound when soaked in milk. Rice Krispies contain lots of sugar and are cooked at high temperature, which makes the sugar ... > 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 -
Acoustical Oceanographers Record Noises in the Deep
Manmade and natural sounds, from boat engines to rainfall, sound different below the sea surface. To study their impact of noise on marine life, scientists are submerging devices called Passive ... > 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
