Man and mouse share genome structures

... the way chromatin is organized, thus allowing the right combination of genes to be turned on. In their study, the researchers analyzed the chromatin structure of the two shortest human chromosomes, numbers 21 and 22, containing about two percent of the human genome. They also sampled additional regions i...

Another Look Finds Promising Proteomics Test is Not Biologically Plausible

...od is unlikely to lead to a reliable clinical test right away. After conducting repeated checks of the data that supported the test’s effectiveness, the researchers say their findings indicate that claims about the experimental protein-based assay are not biologically plausible. “We view this as a cauti...

... scaffold helps direct the engineered cells to the right place, then dissolves once the cells begin to generate to fill in the wound. "In certain kinds of defects, the body cannot heal itself and the body needs a jumpstart," Krebsbach said. To heal a large wound, like that created when a cancerous tumor i...

Genome-wide mouse study yields link to human leukemia

Purdue proves concept of using nano-materials for drug discovery

...lecules to pass. "This allows us to do separation right in the reactor, which means we can do reactions that could not be done before in such a small device. We can study membrane proteins in a fundamentally new way, which is very important because many future drugs to treat diseases will likely work by c...

First-ever Compounds To Target Only Metastatic Cells Are Highly Effective Against Breast, Prostate, And Colon Cancers

...ese analogues into clinical trials. "We're trying right now to get a company interested in this, especially because the mice used in our trial seemed to experience minimal toxicity -- a good sign that patients might tolerate these compounds, too," Dr. Huang said. "It's all very exciting," he said. "Metas...

In such a situation, the contact angle is not determined by the classical Young equation but can vary over a wide range of values. A surprising prediction of the new theory is that the experimentally observed polymorphism of the w...

Why do insects stop 'breathing'? To avoid damage from too much oxygen, say researchers

...ernal oxygen concentration at 4-5 kilopascals, the right oxygen concentration for its body. In a low-oxygen environment, the insect opens its respiratory system for longer periods of time; when it closes the system, it does so for only a very short time. In a stream of air with high oxygen on the other han...

Scientists discover unique microbe in California's largest lake

First real-time view of developing neurons reveals surprises, say Stanford researchers

... moving in a certain direction or near the left or right side of the visual field. What they found was a surprise. As soon as the neurons were old enough to respond to the LCD screen, they specifically fired when they sensed only one type of movement. When the tiny square moved left to right, a distinct p...
