Scientists detect aquatic ecosystem warning signal

Scientists have found what appears to be the stress signals of a lake ecosystem that is on its way to collapse. Stephen Carpenter of the University of Wisconsin, Madison and colleagues carefully monitored the food web in a Wisconsin lake as they gradually introduced largemouth bass into the ecosystem. The researchers noticed a shift in the algae populations that were directly related to the altered feeding behavior of smaller lake...

That is, if all banks are run equally, they are more susceptible to a uniform crisis; much in the way that a...

Tracking the ecological impact of nanotechnology

Scientists are still uncovering the potential uses for nanotechnology. Just this month, researchers have reported on nanotechnology’s potential to eradicate cancer cells and blood diseases, desalinate seawater on the go and convert environmental energy waste to hydrogen fuel. With new research arising daily, it seems nanotechnology could have many applications in medicine and alternative energy. Take, for example, the recent...
