Doggy Genes
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

Help for Thunder-Phobic Dogs
A new study shows that dogs
can get very upset during
thunderstorms, whether or
not their owner holds them.
The study measured the
stress hormone cortisol to
be up to three times normal

Wasps: Man's New Best Friend!
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

Mercury Detection: It's a “Ruff Job”
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'

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 -
Plant Biologists Discover Plant Defenses Against Insects
Plant biologists have identified the strategy used by plants to recognize an attack. When insects ingest parts of a plant digestion turns proteins into a peptide elicitor, which is secreted back into ... > more -
Zoo Focuses Efforts on Poison Dart Frog Breeding Program
The National Aquarium in Baltimore is home to over 16,000 different varieties of animals, so that in one day visitors can travel around the One of the most toxic animals in the world -- the poison ... > more -
Biologists Help Perfumers Capture New Scents from Nature
To increase perfumers' palette with new scents from flowers, biologists now use a device that captures smells. A plant is covered with a glass dome and vapor is extracted and later analyzed. ... > more -
Electrical Engineers Monitor Environment with Robotic Sensors
Fleets of robotic sensors, networking through thin cables, can track environmental changes such as biogeochemical cycles or loss of biodiversity, helping to manage wild lands. The technology is the ... > 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 -
Paleontologists Teach Medical Students About Fossil Tumors
Using medical-physics tools such as CT scans, medical students can learn to recognize a tumor even in a 150-million-year-old dinosaur bone. Paleontologists say the role of disease during evolution ... > 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 -
Environmental Toxicologists Link Household Bacteria to Asthma
Scientists have found that chemicals called endotoxins can inflame airways and trigger asthma. Endotoxins are shed by bacteria in household dust. Experts say better home hygiene, washing bed linens ... > 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
