New ‘Heartland’ disease emerges in U.S. Midwest
A new viral disease causes major pain and flu-like symptoms. At present, no treatment or cure exists.

Wily bacteria create ‘zombie’ plants
Scientists have discovered how some plant pathogens ensure their own survival by transforming flowering plants into strictly leaf-producing ones. These green ‘zombies’ attract insects that the parasites need to help them spread to other plants.

One plus to wearing stripes
A zebra’s black-and-white coat doesn’t offer cooling or camouflage, researchers find. Instead, its stripes appear to keep away biting flies — and deadly diseases.

Loneliness can breed disease
Everyone experiences loneliness from time to time. But when allowed to persist, loneliness can damage your health and steal years from your life.

A success for designer life
Synthetic biologists are scientists who create custom organisms in the lab. Their efforts have just taken a big step forward. They have created the first lab-made yeast chromosome. The advance could lead to entirely synthetic organisms customized to produce food, fuel or medicine.

Sea otters picked up swine flu
A new study finds that large numbers of sea otters off of the U.S. Pacific coast have been exposed to the ‘pandemic’ type of this killer virus.

When a species can’t stand the heat
When temperatures rise, New Zealand’s tuatara produce more males. With global warming, that could leave the ancient reptile species with too few females to avoid going extinct.

Explainer: How invasive species ratted out the tuatara
The introduction of rats to New Zealand led to huge population losses of the ancient tuatara. These uncommon reptiles vanished from the mainland. This left isolated populations to survive on several dozen isolated islands.

Understanding Autism
Genetics appears to play some role in this disorder, which affects more than one percent of all Americans.

Getting a head start on autism
Early diagnosis followed by early treatment may reduce autism’s impact on kids — and help them to communicate better.

Kangaroos have ‘green’ farts
The farts and belches of these animals contain less methane than do those from other big grass grazers. Microbes in their digestive tract appear to explain the ‘roos lower production of this greenhouse gas, a new study finds.

Autism unlocked
Experts are learning how to diagnose this brain disorder in infancy. That may be early enough to allow nerve cells in the brain to develop new connections — ones that form detours around autism-affected areas.
