...volved in disease," says Coles. "The eye itself is telling the stem cells what to do, so when we go to a disease model, it is important to know what those signals from the eye are so we can inhibit them or protect the cells." The other researchers involved in this study are U of T's Prof. Roderick McInnes, a...

New protein identified in development of lung cancer

...quitin to p53 protein. Ubiquitin acts like a flag, telling the cell's recycling center the proteasome that the proteins are ready to be destroyed. Destruction of the proteins essentially cripples p53 and opens the door to malignant transformation. Supporting that notion, the researchers discovered that p5...

Endurance running may be key to evolution of human body form

..."What these features and fossil facts appear to be telling us is that running evolved in order for our direct ancestors to compete with other carnivores for access to the protein needed to grow the big brains that we enjoy today." Protein and fat derived from prey are excellent food for growing the bodies...

...ne to the mouse, and then the gene goes to work -- telling the animal's body to make this antibody against anthrax," Dr. Crystal said. The study found: Once inside the mouse's body, the gene began producing an immune-system antibody targeted to a key component of the deadly anthrax toxin. Mice were immu...

The new generation of airborne radar sensors go one better than ASAR because they include full quad-polarisation capability: this means their signal can be retrieved simultaneously in H and V polarisations, so that by sendin...

Bayou blues: Working to save the US from the worst potential oil, gas and fishing crisis

... and it didn't even have a direct hit. There's no telling how high the price of oil will go years down the line if a severe hurricane directly hits and there are less wetlands to protect the energy infrastructure and the coastline. Besides losing the oil, you'd also face the price of repairing broken pipeli...

Diabetes' link to obesity broken in mice

... he explains. "We thought PPAR-alpha might also be telling cells, look, we have all this fat coming in, so we're not going to need glucose to make energy, so let's shut down glucose burning. And that's exactly what happens in diabetes." To test their ideas, Kelly and lead author Brian N. Finck, Ph.D., resear...

Scientists discover that three overlapping signals in embryo help get the backbone right

What clinched their experiment was taking the organizer from one embryo - in their experiments, a newt - and implanting it into another. "They actually produced a Siamese twin embryo," Khokha said.
