Insects are scared to death of fish

The mere presence of a predator causes enough stress to kill a dragonfly, even when the predator cannot actually get at its prey to eat it, say biologists at the University of Toronto.

New technique elucidates dynamics of plant cell metabolites

A new technique developed by researchers at RIKEN has clarified the location and dynamics of specific metabolites in a single cell of the alga Chara australis. The findings reveal that these metabolites are regulated and ...

A new transporter gene that regulates plant transpiration

When plants feel stress from a lack of water, they close their epidermal pores, or stomata, to prevent water loss via transpiration. Each stoma is flanked by a pair of guard cells, which change shape to close or open stomata ...

Limited iron availability shown to exacerbate coral bleaching

(PhysOrg.com) -- It is widely held that coral bleaching occurs when temperatures and solar radiation are high, overwhelming antioxidant defenses in the algal endosymbionts and their coral hosts. Little understood are the ...

Weather conditions could results in cattle heat stress

Cattle producers should be aware that forecasted weather conditions could result in significant heat stress issues in cattle. The US Meat Animal Research Center predicts danger or emergency conditions through most of South ...

Noise distracts fish from their dinner

Using underwater speakers to play noise at levels similar to those produced by recreational speedboats, the researchers found that three-spined sticklebacks exposed to even brief noise playback made more foraging mistakes ...

Growing drought-tolerant crops inching forward

A collaborative team of scientists led by researchers at The Medical College of Wisconsin, in Milwaukee, has used the tools of structural biology to understand how a synthetic chemical mimics abscisic acid (ABA), a key stress ...
