Precise molecular surgery in the plant genome

Crop plants have always been adapted to the needs of man by breeding for them to carry more fruit, survive droughts, or resist pests. Green biotechnology now adds new tools to the classical breeding methods for a more rapid ...

Plants use circadian rhythms to prepare for battle with insects

In a study of the molecular underpinnings of plants' pest resistance, Rice University biologists have shown that plants both anticipate daytime raids by hungry insects and make sophisticated preparations to fend them off.

New strategy could lead to dose reduction in X-ray imaging

For more than a century, the use of X-rays has been a prime diagnostic tool when it comes to human health. As it turns out, X-rays also are a crucial component for studying and understanding molecules, and a new approach ...

Video shows tool use by a fish
