As a chemical for industrial processes, butanol is used in everything from brake fluid, to paint thinners, to plastics. According to a University of Illinois researcher, butanol made from plant material could displace butanol made from petroleum, just not at the fuel pump.

The nuclei of ordinary hydrogen atoms contain only a single proton. If a neutron is added, the hydrogen becomes deuterium. In principle, molecules that contain deuterium in place of hydrogen atoms are chemically identical. However, there can be significant differences.

During the past 20 years, researchers have identified thousands of cell protein interactions, with the ultimate goal of inventorying all that occur within cells of various organisms – a comprehensive catalogue known as the interactome. Such information will be critical to understanding the basic mechanics of cellular life, and how malfunctions in these processes contribute to cancer.

Did Earth's twin cores spark plate tectonics?
It's a classic image from every youngster's science textbook: a cutaway image of Earth's interior. The brown crust is paper-thin; the warm mantle orange, the seething liquid of the outer core yellow, and at the center the core, a ball of solid, red-hot iron. Now a new theory aims to rewrite it all by proposing the seemingly impossible: Earth has not one but two inner cores.
