A group of Spanish researchers reported today in Science that they may have stumbled upon a substance that could become the ultimate memory-enhancer. The group was studying a poorly-understood region of the visual cortex. They found that if they boosted production of a protein called RGS-14 in that area of the visual cortex in mice, it dramatically affected the animals' ability to remember objects they had seen.
Ancient protein dating back 80 million years to the Cretaceous geologic period has been preserved in bone fragments and soft tissues of a hadrosaur, or duck-billed dinosaur, according to a study in the May 1 issue of Science. Led by scientists at Beth Israel Deaconess Medical Center (BIDMC) and North Carolina State University (NCSU), the new findings support earlier results from analyses suggesting that collagen protein survived in the bones of a well preserved Tyrannosaurus rex, and offer robust new evidence supporting previous conclusions that birds and dinosaurs are evolutionarily related. In April 2007 John Asara, PhD, Director of the Mass Spectrometry Core at BIDMC, together with NCSU paleontologist Mary Schweitzer, PhD, published two papers in Science describing their discovery that collagen extracted from bone fragments of a 68-million-year-old T. rex closely matched the amino acid sequences of modern day chickens. Not surprisingly, the widely publicized findings created a great deal of controversy.
Camel urine, considered an ancient Islamic 'remedy' from the time of the Prophet Mohammed, has become big business for men and women in Yemen.
The urine has become fashionable recently among Yemen's young people, who claim that it strengthens the scalp, slows hair loss and promotes healthy hair.
The advert has upset Muslims because dogs are considered ritually unclean and has sparked such anger that some shopkeepers in Dundee have refused to display the advert.
With gas prices at almost $4 a gallon, many are looking for cheaper ways to get around town.
Three Conner High students are avoiding the pain at the pump, by riding horseback to school.
Tyrannosaurus rex just got a firm grip on the animal kingdom's family tree, right next to chickens and ostriches. New analyses of soft tissue from a T.rex leg bone re-confirm that birds are dinosaurs' closest living relatives.
What would a dog say if it could talk? "Stranger", "fight", "walk", "alone", "ball" and "play", according to scientists who have developed a computer programme to translate dog barks.
