Most new farmland in tropics comes from slashing forests, research shows

A new study shows that more than 80 percent of the new farmland created in the tropics between 1980 and 2000 came from felling forests, which sends carbon into the atmosphere and drives global warming. But the research team also noted that big agribusiness has largely replaced small farmers in doing most of the tree cutting in Brazil and Indonesia, which may make it easier to rein in the trend.

Afla-Guard, a biological control used to thwart the growth of fungi on peanuts, can be used on corn as well, according to a study by agriculture scientists who helped develop it. After extensive study and research trials in Texas, Afla-Guard was registered by the US Environmental Protection Agency for use on corn, beginning with the 2009 crop.

Researchers have revealed new details about how cannibalistic bacteria identify peers suitable for consumption. The work, which employed imaging mass spectrometry, is a first step toward a broader effort to map all signaling molecules between organisms.

Next step in evolution? A technical life form that passes on knowledge and experience

Dutch biologist Gerard Jagers op Akkerhuis has developed the ‘operator hierarchy’ -- a system based on the complexity of particles and of organisms, which can predict the next step in evolution: a technical life form, that can pass on its knowledge and experience to the next generation.
Cows prefer red clover, boost milk production

Cows prefer silage containing red clover, which also boosts their milk production. New research conducted in Finland also discovered that silage made from grass in late summer is no comparison for the same silage made in early summer.
