Seven-year experiment shows that pond communities bear a lasting imprint of random events in their past Scientist Jon Chase once worked in a lab that set up small pond ecosystems for experiments on species interactions and food webs. "We would try to duplicate pond communities with a given experimental treatment," he says. "We put 10 of this species in each pond, and five of these species, and eight of the other species, and 15 milliliters of this nutrient and 5 grams of that and 'sproing,'...

Brain scans show persistent motivation regardless of payoff Whether it's for money, marbles or chalk, the brains of reward-driven people keep their game faces on, helping them win at every step of the way. Surprisingly, they win most often when there is no reward. That's the finding of neuroscientists at Washington University in St. Louis, who tested 31 randomly selected subjects with word games, some of which had monetary rewards of either 25 or 75 cents per correct answer, others of which...

A genetic survey shows very little structure to moray eel populations in the Indo-Pacific. How, then, did 150 species of eel arise there? Joshua Reece became interested in moray eels in 2005 when he was applying to the PhD program at the University of Hawai'i. Instead of taking him on a campus tour, his host, Brian Bowen, PhD, a biologist at the university, took him on a dive.
