California's oak woodlands face a new threat: Climate change
...face intense grazing pressure and competition from invasive
grasses. But the future will bring a new threat--climate change--which could drastically reduce the areas in which oaks can grow. Researchers at the University of California, Santa Cruz, have taken a close look at the implications of climate change ...
Study examines cancer risks after cancer diagnosis in family member

prostate cancer in siblings decreased with time after the diagnosis of the first familial tumor. "The most likely reason for the detection of familial cancers close in time is that the first diagnosis leads to the earlier detection of some asymptomat...

PET imaging reveals the immune system at work
...ent technology to assess immune response relies on invasive
procedures such as biopsies to gather tissue that can be analyzed to determine how well or how poorly the body is faring against disease. The advantage of using the new PET technique, said Witte, is that surgical procedures are avoided and a PET scan...

CO2 sensing proves critical for fungal pathogens to adapt to life in air and human hosts
...ns and C. neoformans. Both cause life-threatening, invasive
infections in immunocompromised patients--for example, those infected with HIV or undergoing bone-marrow transplantation. The two fungi, which are distantly related in evolution, have different attributes governing their virulence in humans. For C. a...
AKT cancer cell pathway demonstrates unexpected function
...ough cell migration is an essential feature of the invasive
phenotype of cancer cells, relatively little information has been available on AKT's role in this key function. As a result, the discovery that this kinase actually blocks cancer cell motility and invasion was totally unexpected. "We asked ourselves,...
