CDC says a toxic compound may be responsible for vaping illnesses
The Center for Disease Control is edging closer to an explanation for vaping-related lung illnesses. The agency has determined that vitamin E acetate, a compound present in all 29 lung tissue samples obtained from patients, is a "potential toxin of concern." The chemical is used to dilute liquid in e-cigarettes and vaping products that include THC, and is found in some food as well as cosmetic products like skin cream. It doesn't normally cause harm when swallowed or rubbed on your skin, but past research suggests that inhaling might impede lung functions.
iPhone 5 chemical study shows a green Apple, leaves room for improvement
Eventually, that shiny new iPhone 5 will have to meet its untimely end, whether it's in a landfill or (preferably) a recycling company's machinery. When it does, you'll at least be glad to know that Apple has kept the toxin levels down. HealthyStuff and iFixit have dissected the extra skinny smartphone and put it in the same "low concern" category for potential harm that's normally occupied by phones wearing their green credentials on their sleeves. Lest anyone rush to tell Greenpeace about the feat, just remember that there's a difference between proficiency at excising dangerous chemicals and getting rid of them completely: HealthyStuff still found small traces of bromine, chlorine, lead and mercury in the iPhone 5's construction, which could pose risks if the handset is ever broken apart or melted for scrap. Some concern also exists that the x-ray fluorescence spectrometer doesn't reveal the full extent of any toxic materials. Whether or not these remain sore points for you, the new iPhone is at least easier on the eco-friendly conscience than most of its peers.
Inhabitat's Week in Green: fluorescent bulb moon, fuel-efficient supersonic jet and a toxin-eating oyster park
Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green. Man-made technology is great, but Mother Nature is the greatest inventor of them all -- and scientists are discovering new ways to take advantage of the tools found in nature. Take, for example, a team of researchers from Vanderbilt University who developed a solar cell using the photosynthetic protein found in spinach. In New York, Scape Studio has proposed to use the oyster's natural cleaning ability to help clean up the contaminated waters of the Gowanus Canal. The firm has received funding to create Oyster-tecture, an oyster park at the mouth of the canal where millions of mollusks will "eat" toxins. Meanwhile, the US Forest Service has been deriving cellulose nanocrystals from wood pulp extract to create a material that's stronger than Kevlar and carbon fiber.
Inhabitat's Week in Green: the dangers of LED lighting, self-healing nanotech, and spray-on solar power
Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green. This week Inhabitat shed light on the next generation of solar power as we showcased a spray-on film capable of generating 300% more energy than traditional photovoltaics and a new breed of nanotech cells that can heal themselves like plants. New biofuel projects also broke ground around the world as the US began construction on its first commercial biofuel plant and Canada upgraded a waste plant to be powered by soda and beer. And another farticle, er, article covers a project in Greenpoint, Brooklyn that takes the result of the results of those drinks (methane) and turns it into fuel. We also interviewed energy efficiency expert David Johnston, who shared 5 tips that could cut your electricity bill by up to 50 percent. And on a more sour energy efficiency note, we were appalled to see this new study that found that LEDs, like CFLs, also contain unsafe levels of carcinogenic toxins. The big (or should we say B.I.G) architecture news of the week was the unveiling of Bjarke Ingels Group's sloping residential pyramid for midtown Manhattan. In transportation news, Nissan revealed plans to roll out its Tesla-trouncing ESFLOW electric supercar at the Geneva Auto Show, while Chevrolet announced that the Volt will receive a $5,000 tax rebate in California. We also applauded the US government's $53 billion plan to jump start high speed rail, while republicans rallied against the movement towards more efficient infrastructure. We also showcased several stylish examples of wearable eco tech - a set of bio sensors that improve physical and emotional health, and a pair of GPS-enabled snow goggles that are perfect for shredding through uncharted territory. Finally, we shared 10 green iPad cases that are perfect for protecting your e-reader from blustery winter weather.
UCSD researchers hope to track airborne toxins with sensor-equipped cellphones
If researchers the world over have their way, cellphones will one day be used to detect and track everything from nuclear radiation to pollution to cancer, and it looks like you can now add one more to the group -- some researchers from the University of California, San Diego have developed a tiny sensor that could eventually let cellphones track airborne toxins in real time. To do that, the researchers have proposed a rather novel system that would consist of a tiny silicon sensor that changes color when it interacts with various chemicals, and a equally tiny camera with a macro lens that would actually capture an image of the sensor and display it on the phone's screen. As you might have guessed, however, while the researchers are now showing off the sensor itself, they still have a ways to go on the cellphone part of the equation -- although they have apparently started work on a prototype.
E-cigarettes contain carcinogens and toxins after all, FDA warns
In case you ever of the mindset that e-cigarettes were somehow toxin free, at least compared to the more traditional smokes, along comes the FDA to shatter your illusions. A report this week from the government agency calls out the product with a safety warning, charging that the cartridges they examined contained "carcinogens and toxic chemicals such as diethylene glycol, an ingredient used in antifreeze." The FDA says it can't confirm the extent of the health issues, as it's only done limited testing and it hasn't been formally submitted for review, but it doesn't look quite as risk-free as previously touted. Don't say the WHO never warned ya. So remind us again, what's the point in smoking one of these over an old school cigarette?[Via Switched; thanks, flatlander85]
