Chemistry
We summarize the week's scientific breakthroughs every Thursday.
- Chemistry
Molecules get microscopic bar code labels
Researchers have created tiny, striped tags for labeling and tracking biologically important molecules.
- Chemistry
Web Elements
Want to know more than just selenium’s symbol, atomic number, and atomic weight? Created by chemist Mark Winter of the University of Sheffield, WebElements provides information on each chemical element’s history, uses, reactions, bulk and thermal properties, and more.

- Chemistry
Novel material fights against cavities
A new material that dentists might eventually put under fillings and braces secretes calcium and phosphate ions to rebuild teeth as cavities form.
- Chemistry
Argon keeps chips and lettuce crisp
A new technique replaces the air in food packages with argon instead of widely used nitrogen, improving taste and shelf life.
- 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.
