View ArticleNoise 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...
View ArticleLimited 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...
View ArticleInsects 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.
View ArticleStress-induced genomic instability facilitates rapid cellular adaption in yeast
Cells trying to keep pace with constantly changing environmental conditions need to strike a fine balance between maintaining their genomic integrity and allowing enough genetic flexibility to adapt to...
