In mice, drug protects against diabetes and atherosclerosis

... more detailed toxicity tests in animals, and then move toward human testing. The important lesson from the new study, the researchers wrote in their report, is the demonstration that aP2 can be blocked by a small-molecule, oral compound. In turn, they add, the results suggest that targeting aP2 "can l...

Salty oceans provide early warning for climate change

...it takes nearly a century for a parcel of water to move from the South Atlantic to the North Atlantic). Instead the scientists think that energy is transferred through the ocean along a deep pressure wave. “The surge of salt generates a pressure gradient in the ocean that sends energy to the north without...

Massive herds of animals found to still exist in Southern Sudan

...efugees and internally displaced people are on the move back into this area, which is causing deforestation east of the Sudd wetlands.” “With the billions being spent annually in Southern Sudan by the international community, almost nothing is being spent on natural resource management, particularly on ...

The project is the first large-scale study to document the relationship of the dimensions of the semicircular canals to locomotion. These structures are filled with a fluid, which moves within the canals wh...

Surprising origin of cell's internal highways

... the microscopic scaffolding that the cell uses to move things around in order to hold its shape and divide, originated from a tiny structure near the nucleus, called the centrosome. Now, researchers at Vanderbilt University Medical Center reveal a surprising new origin for these cellular "highways." In...

Study identifies 5 genetic themes key to keeping stem cells in a primitive, flexible state

...teristics by tightly controlling how molecules can move within the nucleus. The study will be published in the June 20 edition of the online, open-access journal PLoS ONE. “You could call this a ‘theory-of-everything’ for stem cells,” said senior author Dr. Michael Rudnicki, referring to the often-cite...

Scientists close in on missing carbon sink

...vertically in the atmosphere. The models tended to move too much carbon dioxide toward ground level in the summer, when growing trees and other plants take in the gas, and not enough carbon dioxide up in the winter. As a result, scientists believed that there was relatively less carbon in the air above mi...

'Virtual Patient' to simulate real-time organ motions for radiation therapy

Xu expects that the physics-based 4-D VIP-Man will eventually be used as an even more general anatomical modeling tool for the biomedical community to help patients with...

Lessons from the orangutans: Upright walking may have begun in the trees

... Sumatran rainforest and recording virtually every move the orangutans made. Then, she and her colleagues used these observations to test the hypothesis that bipedalism would have benefited tree-dwelling ape ancestors. Because these ancestors were probably fruit-eaters, as orangutans are, they would ha...

Human stem cell treatment restores motor function in paralyzed rats

Frey said this research compares the ability of a new investigational smallpox vaccine called IMVAMUNE® to produce a strong immune response against smallpox disease with another vaccine called Dryva...

Technique monitors thousands of molecules simultaneously

In this way, a wide variety of molecules can be generated and then probed for their biological behavior in real-time," said Moeller. "It's a tool, still being deve...
