New on-off “switch” triggers and reverses paralysis in animals with a beam of light

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...

Scientists are reporting evidence that air pollution — a well-recognized problem at major airports — may pose an important but largely overlooked health concern for people living near smaller regional airports. Those airports are becoming an increasingly important component of global air transport systems. The study, one of only a handful to examine airborne pollutants near regional airports, suggests...

Scientists in China are reporting discovery of unusual liver proteins, found only in males, that may help explain the long-standing mystery of why the hepatitis B virus (HBV) sexually discriminates -- hitting men harder than women. Their study has been published online in ACS’ Journal of Proteome Research, a monthly publication. In a step toward using human saliva to tell whether those stiff joints...

In a step toward using human saliva to tell whether those stiff joints, memory lapses, and other telltale signs of aging are normal or red flags for disease, scientists are describing how the protein content of women’s saliva change with advancing age. The discovery could lead to a simple, noninvasive test for better diagnosing and treating certain age-related diseases in women, they suggest…

A new generation of “green” automobile tires that can boost fuel efficiency without sacrificing safety and durability is rolling through the research pipeline. The new tires could help add an extra mile or two per gallon to a car’s fuel economy. That’s the topic of the cover story of the current issue of Chemical & Engineering News (C&EN), ACS’ weekly newsmagazine. C&EN Senior Editor Alexander Tullo explains that rolling resistance — the friction that tires encounter when rolling — are a major factor in....

  • Must-reads from C&EN: Popcorn butter flavor ingredient subject of numerous lawsuits
    A butter flavor ingredient widely considered safe for consumers is now leaving manufacturers with a bad taste in their mouths. The reason: Hundreds of lawsuits have been filed claiming that the ingredient — diacetyl — causes lung disease in factory workers. Most of the cases involve workers who were exposed to high concentrations of the ingredient during the manufacture of microwave popcorn. Most food makers no longer add diacetyl to their microwave popcorn. To obtain a copy of this story, contact m_bernstein@acs.org
