Climate change plus human pressure caused large mammal extinctions in late Pleistocene

...hment, there are no refuges for animals that might want to relocate because of climate change. "One thing we can do, as conservationists, is to create and connect natural areas" to allow animals to move around, he added. "Because species can no longer do this by themselves, maybe the solution is to do it ...

Scientists to prototype cyberinfrastructure for research and education access to ocean observatories

"One of our biggest challenges is the design of middleware ...

Molecular motor implicated in tissue remodeling

...hey participate in all basic tissue metabolism, we want to understand how they function." Goldberg and his colleagues Savees Saffarian, Ivan Collier, Barry Marmer and Elliot Elson found that MMP-1 operates as a molecular motor--a molecule that converts chemical energy into motion.

Cancer vaccine based on pathogenic listeria bacteria shows promise targeting metastases

... also puts the antigen into exactly the pathway we want and gives us a robust antigen-specific response." Listeria also can avoid antibodies, whereas other microbial vectors set up an antibody response that prevents them from being used more than once. A listeria-based cancer vaccine could thus be given p...

The group's research is providing detailed genetic explanations of how and why c-myb is essential for the proliferation of white blood cells and breast cells by demonstrating t...

Rice finds 'on-off switch' for buckyball toxicity

In other cases -- like applications where particles may make their way into the environment -- toxicity is undesirable." In the study, the researchers exposed two types of human cells to various s...

"If you want to study a conserved biological process, it makes sense to do it in a system where you can do all these genetic tricks," said Campbell of being able to create mutant proteins and manipulate such factors as temperature. "We have an excellent model for...
