...hope for its resurrection now lies in its tame descendants, domesticated cattle. Here's how the process is expected to work: Scientists will first scour old aurochs bone and teeth fragments from museums in order to glean enough genetic material to be able to recreate its DNA. Researchers will then compare the DNA to that of modern European cattle to determine which breeds still carry the creature's genes and create a selective-breeding program to reverse thousands of years of evolution. If everything goes as planned, each passing generation will more closely resemble the ancient aurochs. "Everything will...
...bring different animals back from extinction through breeding. In South Africa, scientists are attempting to recreate the quagga, an extinct subspecies of the zebra, and in the U.S., breeders are trying to bring back a giant Galápagos tortoise that was killed off in the 1800s - a process that could take close to a century. (See "Dinosaur-Era Crocodiles Found in Sahara...
...exact mechanisms by which antenatal depression may affect a child's future behavior are hazy, but researchers think they could have to do with the environment inside the womb and its long-lasting impact on the growing fetus - a process known as "fetal programming." Maternal influences such as alcohol or drug use, poor nutrition and stress are known to affect the level of hormones in the mother's body. It is thought that biochemical changes in the uterus have an impact on the baby's development, affecting its birth weight and even its future risk of disease, among other things...
...also indicates that the sea level was changing rapidly around this time period, rising as much as 1 m the century before, as ice melted, and then falling afterward at around the same speed, as ice began to freeze once more. Rather than forming steadily and melting steadily, the process of glacier freezing and receding may be more more unstable, reflected in sudden rising and falling of the sea level. "It's fair to say that this means glaciers may change somewhat faster than we once inferred," says Jeffrey Dorale, a geoscientist at the University of Iowa and the lead...
...process of starting a new student group to continue the work of changing the culture of Harvard sports fans—from essentially nonexistent to lively and influential. It will be called “The People of the Crimson” and include representatives from the band and the cheerleading squad to ensure a unified assault of intimidation...
