Chemistry
We summarize the week's scientific breakthroughs every Thursday.
- Chemistry
Molecular machines split water
Hydrogen derived from molecular machines that use solar energy to split water, rather than hydrogen from fossil fuels, could drive future fuel cell vehicles.
- Chemistry
Tricky Business
The way a drug crystallizes to form a solid can make or break a billion-dollar product, which explains why pharmaceutical and crystal chemists are racing to control this poorly understood process.
- Chemistry
Velcro Therapy: Branching polymer wards off scarring after eye surgery
Specially designed polymer molecules called dendrimers reduce scar tissue formation after glaucoma surgery, dramatically improving the procedure's outcome.
- Chemistry
Tarantula venom disrupts cells in unexpected way
The unusual way in which the chemical components of tarantula venom disrupt cells could inspire the design of new drug therapies.
- Chemistry
Nitrogen Power: New crystal packs a lot of punch
At extremely high temperatures and pressures, nitrogen gas assumes a three-dimensional crystal structure called polymeric nitrogen, a long-sought energy-storage material.
- Chemistry
Chemistry Catches Cocaine at Source
Scientists have devised a method for identifying cocaine's geographical origin by determining the chemical signatures of five distinct coca-growing regions in the Andes.
- Chemistry
Connection blocker may stop viruses
Using compounds that disrupt the interface of two viral proteins might present a novel strategy for combating viruses, a study of herpes suggests.
- Chemistry
Detailed yellow-bud research blossoms
In identifying the chemical responsible for the color of many yellow flowers, scientists have moved one step closer to engineering sunny-colored designer buds.
- Chemistry
Weighty Discovery: Chemical screening technique identifies potential anthrax drug
A new version of mass spectrometry could speed the process of drug discovery by enabling more accurate screening of thousands of chemicals at once.
- Chemistry
Crystal could generate pure hydrogen fuel
An organic crystal's unusual molecular-trapping behavior could help drive a new hydrogen economy.
- Chemistry
Chemical Knot: Scientists assemble legendary symbol by interlocking molecules
Chemists have constructed a molecular version of a Borromean knot.
- Chemistry
Strange brew brings inorganic chemicals to life
A mixture of inorganic chemicals spontaneously forms cell-like structures that behave like tiny chemical reactors.
