Cats attracted to ADHD drug, a feline poison
Since 2004, drugs designed for use by people have been the leading source of poisonings among companion animals, according to the national Animal Poison Control Center in Urbana, Ill. And among cats, Adderall – a combination of mixed amphetamine salts used to treat attention deficit hyperactivity disorder – has quickly risen to become one of the most common and dangerous of these pharmaceutical threats.

For a lucky few, ‘dioxins’ might be heart healthy
Dioxins and their kin are notorious poisons. They work by turning on what many biologists had long assumed was a vestigial receptor with no natural beneficial role. But it now appears that in a small proportion of people, this receptor may confer heart benefits.

Temporary hearing impairment leads to ‘lazy ear’
A rodent study shows that even after ear infections clear up, brain rewiring may cause long-term hearing problems.

First complete look at families’ genes
Comparing the complete genetic material of family members pinpoints genes involved in three rare inherited diseases.

Scientists offer compelling images of Gulf War illness
BLOG: Researchers have just rolled out a host of brain images — various types of magnetic resonance scans and brain-wave measurements — that they say graphically and unambiguously depict Gulf War Syndrome.

Cocktails ward off the bulge
A large study has found that middle-aged women who drink moderately gain less weight over the years compared to their teetotaling peers.

Ancient Norse colonies hit bad climate times
Temperatures in Iceland plummeted soon after settlers arrived, a new chemical analysis suggests.

Boys and girls differ in genetic response to what mom eats
Expectant mothers’ diets may influence gene activity differently in the placentas that feed sons and daughters, a new mouse study reveals.

Gene linked to pain perception
A common genetic variant that appears to increase sensitivity could lead to the development of better medications.

Green-ish pesticides bee-devil honey makers
Pesticides are agents designed to rid targeted portions of the human environment of undesirable critters – such as boll weevils, roaches or carpenter ants. They’re not supposed to harm beneficials. Like bees. Yet a new study from China finds that two widely used pyrethroid pesticides – chemicals that are rather “green” as bug killers go – can significantly impair the pollinators’ reproduction.

Mature females key to beluga sturgeon survival
Hatchery fish are unlikely to restore caviar-producing fish populations, a new assessment finds.
