New technologies coming too fast for Indian farmers

... previously undocumented pattern of fads, in which each village moves from seed to seed, reflects a breakdown in "environmental learning," leaving farmers to rely on "social learning." Stone refers to this situation as "de-skilling." "The bottom line is that the spread of Bt cotton doesn't so much refle...

Scientists discover new, readily available source of stem cells

...ntation. There are more than 4 million live births each year in the United States. In addition to being easily obtainable, the AFS cells can be grown in large quantities because they typically double every 36 hours. They also do not require guidance from other cells (termed "feeders") and they do not p...

Trusting your instincts leads you to the right answer

...ovements, the team controlled the time allotted to each individual's search for their target. The visual display screen was switched off at various time intervals either before or after the subjects' eyes landed on the target. When the on-screen image was hidden immediately after the subjects' eyes had la...

Scientists clone mice from adult skin stem cells

...rtilized mouse oocytes and replaced the nucleus of each oocyte with a nucleus from these adult skin stem cells. A main hurdle in nuclear transfer with adult cells has been its efficiency ?out of a hundred attempts, only a handful may succeed ?with reported success rates never reaching into double digi...

Insomnia drug can improve brain function

The researchers systematically assessed the effect of zolpidem on motor and cognitive function and explored its effect on brain activity using positron emission tomography (PET) scans. ...

Iowa State University botanists identify new species of North American bamboo

...re of how all the temperate bamboos are related to each other. That means taking inventory of what exists, then comparing notes," Clark said. They already know that the closest relatives of native North American bamboos are not in Central or South America, but are in East Asia. "That's a well-know...

Novel antigen-cloning technique may boost efforts to develop a melanoma vaccine

... genes into recipient cells and match the genes to each T cell type as it permits the B cells to present the peptide to the T cells in context with their own HLA class II. Herlyn and her group now plan to use the RPL8 antigen to develop a melanoma vaccine for patients with advanced disease. "And becaus...

"It can be applied across species and can tell us how social interactions developed in the past and will develop in the future between individuals and among various animal species. "This is important because the most stable ecos...
