Many native plants in the U.S. cannot possibly move themselves fast enough to avoid climate-change driven extinction.

Insecticides may help growers hoping to protect their crops from harmful insects, but they also may contribute to a larger amount of some weeds, according to a study led by researchers at Penn State.

For many plant species, flowering is biologically synced with the seasons. Scientists are clocking blooms to understand our ever-changing planet.

Reducing the amount of agricultural sprays used by farmers — including fertilizers, pesticides and herbicides — could cut down the amount of polluting runoff that ends up in the environment while at the same time reducing farmers’ costs and perhaps even enhancing their productivity.

A forest with high tree-species diversity is better at buffering heat peaks in summer and cold peaks in winter than a forest with fewer tree species.

A groundbreaking study led by Li Yi, professor at the School of Life Sciences, was published in Nature on March 12, titled “Perception of viral infections and initiation of antiviral defence in rice”, uncovering a molecular mechanism by which rice cells perceive viral infections and initiate antiviral response, which significantly contributes to understanding of virus-host interactions for further disease resistance breeding.

New research finds that microalgae in northern peat bogs will absorb more carbon dioxide as the planet warms, helping to take a bite out of emissions.

In the spring of 1994, David Noble rappelled down the sheer cliff of a narrow canyon, part of a tangled maze of escarpments deeply incised into the sandstone tablelands in Australia’s Wollemi National Park, some 90 miles northwest of Sydney.

Cancer drugs and agrichemicals can be powerful, but toxic, tools.

At TU Wien (Vienna), methods are being developed to extract valuable substances from biomass – and quantum cascade lasers offer some very interesting new possibilities.
