Injured plants send chemical signals to neighboring plants
Harsh Bais, a botanist at the University of Delaware, and a high school student collaborated to understand how plants behave when they feel threatened. They studied about a thousand Arabidopsis thaliana or mustard weed plants that were grown in the lab in petri dishes. It was found that when one... 阅读更多

How animals detect and react to high temperatures
To understand behavioral responses of animals to fast and slow rise in temperature, researchers at the University of California - Santa Barbara conducted a study on fruit fly larvae. They found that a quick rise in temperature to 25 degrees stimulated a writhing response in the larvae. On the... 阅读更多
