Chemistry
We summarize the week's scientific breakthroughs every Thursday.
- Chemistry
Energy in Motion
The molecular machines of living cells harvest energy out of randomness, and scientists are learning how to do the same with artificial molecules.
- Chemistry
Chomping on uranium
Chemists forced the most common form of uranium into a new kind of chemical reaction, which could lead to new industrial applications and new tools to clean up the environment.
- Chemistry
Hydrogen makers
A new bioreactor produces hydrogen hundreds of times as fast as previous prototypes.
- Chemistry
Chemistry—Weird and Otherwise
During this—Chemistry Week—check out the “Who, What, When, Where, and Why of Chemistry.” The site’s periodic postings are offered up by Bryn Mawr College computational chemist Michelle M. Francl, who comments on events of the day—always inserting a gentle chemistry twist. She notes that her blog “began as part of an NSF grant to write […]
- Chemistry
Platinumfree fuel cell
Cheaper than a typical hydrogen fuel cell, a new, platinumfree cell runs on a "green" liquid fuel.
- Chemistry
Nanotherapy: Gold-drug combo could target tumors
Clusters of paclitaxel molecules attached to gold nanoparticles could deliver a safer and more effective chemotherapy punch to tumors.
- Chemistry
Kitchen Chemistry
Play with your food. That’s encouraged at this Countertop Chemistry site. Its kitchen-based teaching projects have been compiled by the Science House, an educational outreach program of North Carolina State University. Go to: http://www.science-house.org/learn/CountertopChem/
- Chemistry
Nanoparticles multitask
Magnetite nanoparticles have catalytic properties that may be useful in wastewater treatment and biomedical assays.
- Chemistry
Alien Pizza, Anyone?
Although many biochemical molecules come in left-handed and right-handed versions, life on Earth uses one version exclusively, and some controversial experiments suggest this preference might not be due to chance.
- Chemistry
Soot Sense: Test tallies exposure to diesel pollution
A chemical in urine reveals a person's exposure to diesel exhaust.
- Chemistry
Gooey solution to a sticky problem
A new, gooey, and potentially useful protein has been extracted from the bodies of jellyfish that overpopulate the seas around Japan.
- Chemistry
A sweet way to replace petroleum?
Thanks to a new chemical process, many products now manufactured from petroleum could one day be made from sugar molecules.
