Chemistry
We summarize the week's scientific breakthroughs every Thursday.
- Chemistry
Delivering the Goods
Experimental gene-delivery therapies generally use viruses to shuttle genetic material into cells, but some researchers are devising ways to avoid using the sometimes-risky viruses.
- Chemistry
Jet Streams: Droplet behavior captured by high-speed camera
A series of images has captured charged droplets spouting microscopic jets of fluid, a phenomenon that was proposed by Lord Rayleigh in 1882.
- Chemistry
Soy and oat combo protects against UV
Soybean oil and a natural chemical in oat bran have been chemically combined to make a new sunscreen.
- Chemistry
Photography at a Crossroads
Researchers are racing to understand the chemical processes used during the past 2 centuries to make photographs before digital-imaging techniques take over completely.
- Chemistry
Dipping deeper into acid
New experiments reveal how a molecule of acid dissolves in water.
- Chemistry
Hydrogen: The Next Generation
Researchers are looking for more sustainable ways to generate hydrogen, which burns cleanly but is typically made from fossil fuel.
- Chemistry
Hot Spuds: Golden path to acrylamide in food
The browning reaction that imparts flavor to french fries and breads also creates acrylamide, an animal carcinogen.
- Chemistry
The Dirt on Art: Chemists test laser cleanup of paintings
A new experiment shows that lasers can be a safe tool for cleaning paintings.
- Chemistry
Money Allergies: Two-toned euro coins shed metallic allergen
The two-alloy composition of some euro coins makes them release large amounts of nickel, a common skin allergen.
- Chemistry
Wine Tasting: Instrument can sniff out vinegar in sealed wine
A new system could determine whether a sealed bottle of wine has turned to vinegar.
- Chemistry
Germ Fighter: Lens coating may keep contacts in eye longer
A new antibacterial coating may allow contact lenses to remain in a person's eyes for up to 3 months.
- Chemistry
Down to the bone
A new method for making bone cement could simplify hip and knee replacements and improve the surgeries' outcomes.
