The data may help stem cell researchers understand the mechanisms that determine whether stem cells divide or differentiate, what types of cells they become…
“Today, the middle of Wyoming is a vast desert, and a few antelope and deer are all you see,” said lead author Michael Woodburne, honorary curator of geology…
While banded birds are sometimes seen in the area where they were originally released, it is very rare to see them so far from a release site.The observation…
They conducted a simple genetic test to identify the presence of the unusual form of the gene, the so-called M allele that other researchers had suspected…
The new work, described in the August 6 issue of Science Express,* overcomes significant hurdles in scaling up ion-trapping technology from small…
Effective response by key immune cells in the body, called T cells, is crucial for control of many widespread chronic viral infections such as HIV and…
In 1957, shepherds in Idaho (USA) discovered that when pregnant sheep ate lilies of the species Veratrum californicum (corn lily, California false hellebore),…
The genetic information was obtained using pyrosequencing technology in the Keck Center at the U of I. The genetic sequence will allow scientists to study…
If you are a woman who dines with a man, chances are you choose food with fewer calories than if you dine with a woman. That is one of the findings in a study…
Sangwon Suh and colleagues point out in the study that annual bioethanol production in the U.S. is currently about 9 billion gallons and note that experts…
This striking view is ablaze with a flurry of stars of all colours and brightnesses, some of which are seen against a backdrop of clouds of dust and gas. One…
Pyruvate carboxylase is a metabolic enzyme that plays a fundamental role in the metabolism of fatty acids (the components of fats) and sugars. When its…
The results of this research project, which was initiated in 2005 and is supported by Bizkaia:Xede and the Basque Government's Etortek programme, were…
The study, the cover story in the Aug. 6, 2009, issue of the journal Nature, also opens the door for further research which could accelerate the development of…
It is important to understand what biological mechanisms contribute to an individual's capacity to be resilient under conditions of extreme stress, such as…
To use hydrogen as a clean energy source, some engineers want to pack hydrogen into a larger molecule, rather than compressing the gas into a tank. A gas flows easily out of a tank, but getting hydrogen out of a molecule requires a catalyst. Now, researchers reveal new details about one such catalyst. The results are a step toward designing catalysts for use in hydrogen energy applications such as fuel cells. Scientists from the Department of Energy's Pacific Northwest National…
