Scientists in Poland are describing how a medical imaging technique has taken on a second life in revealing forgery of an artist’s signature and changes in inscriptions on paintings that are hundreds of years old. A report on the technique, called optical coherence tomography (OCT), is in ACS’ Accounts of Chemical Research, a monthly journal. Piotr Targowski notes that easel...
Scientists in Texas are reporting that a technique used in the search for new drugs could also be used in the quest to discover new, environmentally friendly materials for fighting global warming. Such materials could be used to capture the greenhouse gas carbon dioxide from industrial smokestacks and other fixed sources before it enters the biosphere. The new study appears in ACS’...
Scientists have published the first report on a new way of preventing potentially harmful plasticizers — the source of long-standing human health concerns — from migrating from one of the most widely used groups of plastics. The advance could lead to a new generation of polyvinyl chloride (PVC) plastics that are safer than those now used in packaging, medical tubing, toys, and other products...
In an advance with overtones of Star Trek phasers and other sci-fi ray guns, scientists in Canada are reporting development of an internal on-off “switch” that paralyzes animals when exposed to a beam of ultraviolet light. The animals stay paralyzed even when the light is turned off. When exposed to ordinary light, the animals become unparalyzed and wake up. Their study appears in the Journal....
Amid concern about the potential toxic effects of the fluorochemicals used in nonstick cookware, water-repellent clothing, and other consumer products, manufacturers are using new versions of these chemicals that may be safer. That’s the topic of the cover story in the current issue of Chemical & Engineering News (C&EN), ACS’ weekly newsmagazine. C&EN Senior Editor Stephen K. Ritter cites indications that long-chain compounds like perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) can cause…

- Must-reads from C&EN: Valentine treats too sweet for words
The cloyingly sweet taste of those tiny candy hearts and other Valentine’s Day treats are a reminder that too much of a good thing — sweet taste, in this case — can be bad. Food scientists actually are searching for sweetness inhibitors and zinc salts that block the perception of “sweet” as possible solutions. For a copy of the story, go to too sweet.
