Crop competition as a weed control strategy

A new study featured in the journal Weed Science points to the formidable weed control challenges faced by growers today. Weeds have developed resistance to many existing herbicide options, and new herbicide discoveries have plummeted. As a result, nonchemical approaches are growing in importance.

Mapping millet genetics

In the semi-arid tropics of Asia and Africa, conditions can be difficult for crops. Plants need to have short growing seasons, survive on poor soils and tolerate environmental stresses.

Ornament with eagle talons from Neanderthal Period

Eagle talons are regarded as the first materials used to make jewellery by Neanderthals, a practice which spread around Southern Europe about 120,000 and 40,000 years ago.

Impact of water droplets on leaves quickly triggers stress responses in plants

In contrast to humans, plants cannot feel pain. However, so-called mechanical stimulation -- rain, wind and physical impact from humans and animals -- contributes to the activation of a plant's defence system at a biochemical level. This in turn triggers a stress hormone that, among other things, can lead to the strengthening of a plant's immune system.
