Some Insects Are Picky About What Wind to Ride

For a high-flying insect, long-distance migration must be easy. The bug just ascends to a height where the air is zipping along — about 500 to 2,500 feet — and heads whichever way the wind blows.

Spring comes 11 days early (at least that's what birthing British wildlife think)

So that's why John Wayne always won the Wild West duels - he waited for the baddie to go for his gun first

Scientists identify gene linked to biological agei ...

Biological ageing, as distinct from chronology ageing, includes changes in the physical structure of the body as well as changes in the performance of motor skills and sensory awareness.

Researchers map the soybean genome

Researchers, funded by the US Department of Energy, have completely mapped the soybean genome, according to a study published in Nature magazine. They have also begun comparing soybean DNA to traits in the growing plant, allowing scientists to select for desirable characteristics such as plant hardiness, digestibility, disease resistance, and reduced environmental impact.

Earth: Bizarre Giant Fish Filmed

A huge oarfish was caught on camera in the Gulf of Mexico recently, giving scientists a rare glimpse of the bizarre fish in its native deep sea habitat. Researcher Mark Benfield describes the fish, a likely inspiration for the sea serpent myth. Earth: Bizarre Giant Fish Filmed More Videos Online

Researchers have discovered that some animals can actually breathe underwater. Discovery News' James Williams dives deep for the details. Animals: Submerged Sense of Smell More Videos Online

Dinosaur Discovery Helps Solve Piece of Evolutionary Puzzle

TEHRAN (FNA)- A George Washington University expedition to the Gobi Desert of China has enabled researchers to solve the puzzle of how one group of dinosaurs came to look like birds independent of birds.

Enhancing arrest of cell growth to treat cancer in mice

A team of researchers, led by Pier Paolo Pandolfi, at Beth Israel Deaconess Medical Center, Boston, has identified a new type of cellular senescence (i.e., irreversible arrest of cell growth) and determined a way to enhance it to suppress prostate tumor development and growth in mice.
