Animals
Researchers at the University of Southern California (USC) have, for the first time in history, derived authentic embryonic stem (ES) cells from rats. This breakthrough finding will enable scientists to create far more effective animal models for the study of a range of human diseases.
The BBC reports that in Finland, a car thief was identified from his DNA -- DNA taken from blood found in a mosquito inside the stolen car.
In a study that challenges current ideas about the insect brain, researchers have found that honey bees on cocaine tend to exaggerate.
Biologists have tracked down genes that control the handedness of snail shells, and they turn out to be similar to the genes used by humans to set up the left and right sides of the body.
A previously unknown mutation discovered in a common roundworm holds the promise of new treatments for obesity in humans, McGill University researchers say.
Big males outperform smaller ones in head-to-head mating contests but diminutive males make ten times better lovers because they're quicker to mature and faster on their feet, a new study of redback spiders reveals.
What is a kakapo? Who is supporting their cosnervation?
Scientists have discovered that management efforts intended to assist migrations of salmon and steelhead trout can have unintended consequences for fish populations. Juveniles that are transported downstream on boats can lose the ability to migrate back to their breeding grounds, reducing their survivorship and altering adaptations in the wild.
The first robot that can jump like a grasshopper and roll like a ball could play a key role in future space exploration.
A Duke University study suggests that evolution can behave as differently as dogs and cats. While the dogs depend on an energy-efficient style of four-footed running over long distances to catch their prey, cats seem to have evolved a profoundly inefficient gait, tailor-made to creep up on a mouse or bird in slow motion.
The pod of pilot whales stranded on Anthony's Beach near Stanley Tasmania were injured 25 days prior to beaching by a magnitude 5.1 earthquake in the seafloor below where the pod was feeding.
Jealousy. Obsessive stalking. Cross-dressing. Strangulation. Once-in-a-lifetime sex.
A single hit on the head by the termite Termes panamensis (Snyder), which possesses the fastest mandible strike ever recorded, is sufficient to kill a would-be nest invader.
Sandcastle worms live in intertidal surf, building sturdy tube-shaped homes from bits of sand and shell and their own natural glue.
Darwin's anniversary, the tale of the mockingbirds, and Lonesome George.
