How to look at dinosaur tracks

... “The tracks and undertracks of large theropods found in the [Middle Jurassic] Entrada Sandstone at the studied locality come in a wide range of morphologies, mainly as a result of present-day erosion that has exposed the track-bearing surfaces at different depths,?the researchers explain. “[They] demon...

A cherry on top: Tart cherries may alter heart/diabetes factors

...antioxidant compounds called anthocyanins that are found in tart cherries. The new results were given today in an oral presentation at the Experimental Biology 2007 meeting in Washington, D.C. It's not yet known if cherry-rich diets might have a similar impact in humans, but a U-M team will soon launch...

Does amateur boxing cause brain damage?

...0 healthy men who were not athletes. The study found high CSF levels of neuronal and glial markers suggestive of brain damage after a fight. A particular marker for neuronal damage, neurofilament light (NFL), was four times higher in boxers within 10 days of the fight as compared with healthy non-athl...

Technique monitors thousands of molecules simultaneously

...tor, washing away any excess receptor that has not found a key, and then treating the bound receptors with an antibody that recognizes the receptor and is tagged to a fluorescent label. The washing step risks removing a bound receptor if it does not bind the molecular key strongly enough. But, with an elec...

'Insulator' helps silence genes in dormant herpes virus

...ons indicative of silenced chromatin. The patterns found resemble well-studied regions where insulators are found in both yeast and chicken, namely the yeast mating loci and chicken globin locus. To see if insul...

How the brain's backup system compensates for stroke

... which reflects brain activity. The researchers found that the magnetic pulses to the left PMd briefly disrupted the subjects' performance on the task, but that performance quickly recovered. The fMRI scans revealed that during this behavioral recovery, the right PMd and other areas involved in premotor...

The sound of proteins

Miller from the University of California, Los Angeles, USA, have so far transcribed segments of two human proteins into music. But to make their melodies more pleasing on...

Vaccine prevents prion disease in mice

...ous agent. The proteins are so similar to proteins found normally that the immune system does not fight them off. To develop a vaccine that would stimulate the mice's immune system, researchers attached prion proteins to a genetically modified strain of Salmonella. For the study, the mice were orally v...

Keeping the immune system from starting a 'food fight'

...ell, a publication of Cell Press. The researchers found that animals lacking a protein enriched in fat cells, called STAMP2, develop acute inflammation in deep pockets of visceral fat. The animals also showed symptoms of metabolic syndrome—including insulin resistance and fatty liver disease—even while ea...

Master regulatory gene of epithelial stem cells identified

...al stem cells has been controversial. Some studies found that p63 maintains a steady pool of the regenerative cells, while other studies argued that p63 has more to do with causing the cells to differentiate into particular types of tissue. The study, which was lead by Frank McKeon, PhD, professor of cell ...
