Cone of poison: The secret behind the cone snail’s venom pump
Scientists have discovered the secret of how an amazing sea snail injects its venom after shooting a harpoon-like tooth into its prey — or some unlucky swimmer — at jetliner speeds. The creatures, called cone snails, use a highly specialized structure that instantly pumps the paralyzing venom through the tooth and into its target. Their study appears in ACS’ monthly Journal of…
Tobacco and its evil cousin, nicotine? They’re good — as a pesticide!
Tobacco, used on a small scale as a natural organic pesticide for hundreds of years, is getting new scientific attention as a potential mass-produced alternative to traditional commercial pesticides. That’s the topic of a report in ACS’ bi-weekly journal Industrial & Engineering Chemistry Research…
Small particles show big promise in beating unpleasant odors
Scientists are reporting development of a new approach for dealing with offensive household and other odors — one that doesn’t simply mask odors like today’s room fresheners, but eliminates them at the source. Their research found that a deodorant made from nanoparticles — hundreds of times smaller than peach fuzz — eliminates odors up to twice as effectively as today’s gold…
Concerns about the safety of certain “healthful” plant-based antioxidants
Scientists are calling for more research on the possibility that some supposedly healthful plant-based antioxidants — including those renowned for their apparent ability to prevent cancer — may actually aggravate or even cause cancer in some individuals. Their recommendation follows a study in which two such antioxidants — quercetin and ferulic acid — appeared to aggravate kidney…
Probing the mysterious second-wave of damage in head injury patients
Why do some of the one million people who sustain head injuries annually in United States experience a mysterious second wave of brain damage days after the initial injury — just when they appear to be recovering? Limited clinical trials using an innovative new device to monitor brain chemistry on a second-by-second basis are underway to answer that life-and-death question, according…
