We summarize the week's scientific breakthroughs every Thursday.
- 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.
- Chemistry
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.

Perfecting Porosity
Researchers are designing novel porous materials that could clean up toxins, store gases, or catalyze difficult chemical reactions.
- Chemistry
Chemists decorate nanotubes for usefulness
Researchers have developed a new technique for attaching groups of atoms to the sides of carbon nanotubes, creating compounds with extraordinary strength and conductivity.
- Chemistry
Hassium holds its place at the table
Researchers have performed the first ever chemical studies on the element hassium.
- Chemistry
Chemists make hard-to-catch molecules
Chemists have devised a new way to stabilize highly reactive molecules called carbenes.

Molecular Chemistry Takes a New Twist
New calculations show that a basic tenet of chemistry is wrong: Ethane forms its most stable structure not due to so-called steric effects, but because of a quantum mechanical influence.
- Chemistry
Designer surface proves deadly to bacteria
Researchers have made a surface coating that kills bacteria on contact in a novel way.
- Chemistry
Cosmic Chemistry Gets Creative
By simulating extraterrestrial impacts on Earth, researchers are firing away at the question of how life started.
- Chemistry
Rocks May Have Given a Hand to Life
In a new twist to the puzzle of how life developed from only left-handed amino acids, researchers have found that the common mineral calcite can segregate the molecules into their left-handed and right-handed varieties.
- Chemistry
Liver cells thrive on novel silicon chips
Researchers have coaxed finicky liver cells to grow on porous silicon chips, a feat that could lead to new medical treatments.
- Chemistry
Leaden news for city neighborhoods
Researchers have identified more than 400 urban sites that may be highly contaminated with lead but had remained unknown to authorities for decades.
