Tundra disappearing at rapid rate

...th century was observed at all locations. Treeline advanced considerably—as much as 85 metres elevation—on warm, south-facing slopes and tree density increased significantly—as much as 65 per cent—on cooler, north-facing slopes. "The mechanism of change appears to be associated with occasional years of ex...

30+ AIDS vaccine clinical trials in 24 countries, research occurring on every continent

...a expected later this year. Two of the most advanced trials underway in 2007 are from Sanofi-Pasteur and Merck & Co., Inc.

Ancient genes used to produce salt-tolerant wheat

...heat variety as salt-tolerant as bread wheat is in advanced field trials and could be commercially available in three years. Even better durum wheats are in development and the program has been expanded to include bread wheat. "Bread wheat is quite tolerant to salt, but we think it too can be improved. Our...

Researchers identify ovarian cancer biomarkers

... 20 percent survival among patients diagnosed with advanced disease. "All the things we could hope for are present with this approach: It has potential for diagnosis, imaging, treatment and prognosis. It needs more work and much more confirmation, but our early results are promising," Buckanovich says. ...

Imaging pinpoints brain regions that 'see the future'

... from Washington University in St. Louis have used advanced brain imaging techniques to show that remembering the past and envisioning the future may go hand-in-hand, with each process sparking strikingly similar patterns of activity within precisely the same broad network of brain regions. "In our daily l...

Stem cells act through multiple mechanisms to benefit mice with neurodegenerative disease

...shed in Nature Medicine, will be made available by advanced publication at the journal's website on March 11, 2007. To determine whether stem cell biology might play a role in benefiting degenerative diseases, the investigators first chose to approach, as proof-of-concept, a mouse model of a representative l...

A genetic 'gang of 4' drives spread of breast cancer

...ocks the action of epiregulin and is used to treat advanced colorectal cancer. Celecoxib is an inhibitor of COX2 that is used as an anti-inflammatory, and is being tested in clinical trials against many types of cancer. The researchers also tested whether cetuximab and celecoxib would work effectively in conc...
