Massive herds of animals found to still exist in Southern Sudan

...traveled in a modified Cessna 182 just hundreds of feet above the ground for 70,000 miles (112,650 km) to create an unprecedented record of human impact on the land. A survey of Southern Sudan was part of the initial planning for the trip, but Fay was unable to complete his surveys due to political obstac...

CT scan reveals ancient long-necked gliding reptile

...or less. The researchers could determine that the feet were curved, indicating that the reptiles probably lived in trees. The resolution of the CT scan is largely dependent on the size of the object to be scanned. Because the researchers did not want to cut up the sheet of rock in which the fossiliz...

Scientists map key landmarks in human genome

...ave multiple functions, including allowing several feet of DNA to be packed tightly into a cell's nucleus. They also regulate gene expression, or activity, by determining whether DNA sequences can be accessed by transcription factors, allowing the factors to regulate expression of a nearby gene.

...trol in the spinal cord ?extending as far as three feet in adult humans. These neurons degenerate in ALS and related disorders, and their damage contributes to loss of motor function in spinal cord injuries.
