Chemistry

Tiny spheres may deliver oral insulin

Researchers have developed microscopic spheres that can sneak insulin past the stomach so it can be absorbed in the small intestine.

Chemistry

Faster, Better, Cleaner?

Chemists have found that a new class of compounds, called ionic liquids, can substitute for widely used, messy organic solvents while also performing better and producing new products of interest to industry.

Chemistry

Feline stimulant fends off mosquitoes

Preliminary results suggest that catnip may be more effective at repelling mosquitoes than the widely used chemical DEET.

Chemistry

Chemists redesign natural antifreeze

Researchers have synthesized a family of artificial molecules that resemble the compounds that keep Antarctic and Arctic fish from freezing.

Chemistry

Carbon-70 fullerenes finally link up

Researchers have coaxed the cage-like molecules of carbon-70 into zigzagging polymers.

Chemistry

Chemists make molecules with less mess

Researchers have found a way for a widely used, commercially important chemical reaction to produce less pollution.

Chemistry

Chemistry of Colors and Curls

Chemists are using new technology and experiments to discover how hair becomes damaged and how to protect it.

Chemistry

Researchers take an element off the table

Researchers have retracted their 1999 claim that they had created the heaviest member of the periodic table so far, element 118.

Chemistry

Longest carbon-carbon bonds discovered

Researchers have found a type of carbon-carbon bond that's twice as long as the longest naturally occurring bond linking two carbon atoms.

Chemistry

Carbon nanotubes show superconductivity

Researchers have made individual superconductive carbon nanotubes that are just 0.4 nanometer wide.

Chemistry

Wee dots yield rainbow of molecule markers

Chemists report a scheme for creating a versatile color-based tagging system out of tiny atomic clusters, called quantum dots, that may enable scientists to track biomolecules with more finesse than ever.

Universe of Molecules

For chemistry students, Molecular Universe offers a host of images, explanations, and other resources concerning molecules and chemical systems. Developed by Richard Catlow of the Royal Institution of Great Britain, the site features lessons and material on protein folding, the molecular basis of taste, and many other topics.
