Bioethanol's impact on water supply 3 times higher than once thought
At a time when water supplies are scarce in many areas of the United States, scientists in Minnesota are reporting that production of bioethanol often regarded as the clean-burning energy source of the future may consume up to three times
more water than previously thought. Their study appeared ...

As sticky as a gecko... but 10 times stronger!
The gecko's amazing ability to stick to surfaces and walk up walls has inspired many researchers to manufacture materials that mimic the special surface of a gecko's foot. The secret behind the gecko's ability to stick so well is a forest of pillars at the micro-/nano-scale on the underside of the...
