Less resistance can sometimes be better than more--at least in a freshwater lake When battling a deadly parasite epidemic, less resistance can sometimes be better than more, a new study suggests. A freshwater zooplankton species known as Daphnia dentifera endures periodic epidemics of a virulent yeast parasite that can infect more than 60 percent of the Daphnia population. During these epidemics, the Daphnia population evolves quickly, balancing infection resistance and reproduction....

When it comes to battling a deadly parasite epidemic, it may be better not to fight it.  A new study of freshwater zooplankton suggests less is more when it comes to evolving against a parasitic epidemic. The zooplankton, known as Daphnia dentifera, has been found to endure a yeast parasite infection known to affect more than 60% of its population. What scientists found interesting is how quickly the Daphnia population evolves, balancing infection, resistance, and reproduction....

Researchers Determine Why Wine Aeration Works
2011-11-23 06:17:27

Researchers have determined how the process of swirling wine around in a glass to aerate the liquid actually works. The team generated waves in clear cylinders and used state-of-the-art instrumentation to track the motion of traveling waves and measure the liquid velocity. The team found that "as the wave propagates along the glass wall, the liquid is displaced back and forth from bottom to top and from the center to the periphery," Mohamed Farhat, senior scientist at the Ecole...

  An angry glare from the family goldfish might not be the result of a missed meal, but a too-humble abode.

"The welfare of aquarium fishes may not seem important, but with that many of them in captivity, they become a big deal," said Ronald Oldfield, an instructor of biology at Case Western Reserve. Why,...
