		<description><![CDATA[Scientists are developing a salt-resistant rice variety after a huge tsunami last year hit paddy fields in Japan leaving behind a salty sludge. Farmlands that accumulate salt have lower crop yields, which can threaten food supply, as rice happens to be the staple of billions of people worldwide. &#8220;The beauty of the new method (called [...]]]></description>

		<description><![CDATA[Genetic factors only partially affect our lifelong intelligence levels, while environmental causes seem to exert the largest influence. In a number of studies since early 2000, researchers have shown that when people took intelligence tests as children and then again in old age they tended to keep about the same relative score. However, there was [...]]]></description>

Scientists stumbled on the signal while trying to understand how different parts of the cell chat with one another in the Arabidopsis thaliana, a kin of canola, under drought conditions. A series of connected pathways, like [...]]]></description>

A new study has found that such insect predators, given a choice of food, will select a diet that maximises their chances of reproducing. &#8220;Contrary to standard dogma, predators do balance their diet and show nutritional [...]]]></description>

Researchers say that glia cells, which had long puzzled scientists, are central to the brain&#8217;s adaptability, learning and information storage. Actually, glia cells do much more than hold the brain [...]]]></description>

The findings may provide insight into human decision-making as well. The team [...]]]></description>
