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 ...

The last supper of the hominids establishes the times they lived at the sites

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...
