Chemistry
We summarize the week's scientific breakthroughs every Thursday.
- Chemistry
New sensor can ID dangerous bacteria
When newly created organic molecules, called TWTCPs, are attached to a porous silicon wafer and exposed to a certain class of bacterium, the wafer changes color.
- Chemistry
Chemists Try for Cleaner Papermaking
Chemists have developed a novel technology that could help clean up the papermaking process.
- Chemistry
Bitter truth about beer comes to a head
Chemists have figured out exactly how beers develop a skunky flavor and smell.
- Chemistry
Milk protein does a membrane good
Chemical engineers have created a new type of durable membrane from whey protein, a natural component of milk.
- Chemistry
Molecules, like Tinkertoys, link up
Researchers have tailored molecules so that they self-assemble into predictable shapes on a gold surface.
- Chemistry
Nobel recognizes three for handy chemistry
The 2001 Nobel Prize in Chemistry honors research that led to new chemicals, materials, and drugs, including widely used heart medicines.

Nobel prize: Chemistry
The 2001 Nobel Prize in Chemistry recognizes the development of molecules for catalyzing fundamental reactions used to make countless pharmaceuticals.
- Chemistry
Burned by Flame Retardants?
One particular class of flame retardants—polybrominated diphenyl ethers—is accumulating at alarming rates in the environment, taints human breast milk, and has toxic effects similar to the now-banned PCBs.
- Chemistry
Molecules get microscopic bar code labels
Researchers have created tiny, striped tags for labeling and tracking biologically important molecules.
- 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.
