Asthma Inhalers To Go Green

Asthma Inhalers Going Green
By the end of the year, 22 million Americans who suffer from asthma will have to switch to a new, environmentally-friendly type of inhaler. Dr. Emily Senay reports. |

(CBS/ AP) Old-fashioned asthma inhalers that contain environment-harming chemicals will no longer be sold at year's end - and the U.S. government is urging patients not to wait until the last minute to switch to newer alternatives.

Patients use inhalers to dispense airway-relaxing albuterol during asthma attacks.

Chemicals called chlorofluorocarbons, or CFCs, once were widely used to propel the drug into the lungs. But CFC-containing consumer products are being phased out because CFCs damage the Earth's protective ozone layer. As of Dec. 31, asthma inhalers with CFCs can no longer be made or sold in the U.S. Inhalers instead will be powered by ozone-friendly HFAs, or hydrofluoroalkanes.

The ozone layer shields the planet from harmful ultraviolet radiation.

Patients have been warned of the change for several years, but the U.S. Food and Drug Administration issued an advisory last week saying anyone still using CFC inhalers should ask their doctor about switching now.

The FDA warns that patients will face a learning curve: HFA inhalers may taste and feel different. The spray may feel softer. Each must be primed and cleaned in a specific way to prevent clogs. And they tend to cost more.

Users will have to wash the plastic mouthpiece more frequently and dry it overnight, CBS' The Early Show medical correspondent Dr. Emily Senay said.

CFC-free albuterol inhaler options include GlaxoSmithKline's Ventolin HFA, Schering Plough's Proventil HFA and Teva Specialty Pharmaceuticals' ProAir HFA. Sepracor's Xopenex HFA is also CFC-free, but it contains levalbuterol, a similar medication.

The FDA said Armstrong Pharmaceuticals is the sole remaining maker of CFC inhalers and is expected to stop production even before the deadline. A spokesman for Armstrong's parent company would not say when production would stop, but sales of remaining inventory will continue until Dec. 31.

Soaring Over the Alps on Homemade Jet Wings

By Dave Demerjian May 16, 2008

Playing to a mesmerized audience, Swiss pilot and adventurer (some might say nutcase) Yves Rossy has soared above the Alps with homemade jet-powered wings strapped to his back.

Rossy, an extreme sports guy who has spent years assembling his wings, casually stepped out of an airplane at 7,500 feet, unfolded the wings and quickly passed from free fall to mellow glide. He then fired up the wings' engines and accelerated to more than 180 mph.

As if that weren't cool enough, Rossy showed off a bit, making a few dives, some figure eights and a 360-degree barrel roll before landing at an airfield near Lake Geneva.

"That was to impress the girls," he said after the five-minute flight.

It's not your average DIY project, but then again Rossy doesn't seem to be your average guy. One look at the video proves that.

Fusionman, as the 47-year-old adventurer calls himself, is intimately familiar with flight. As a military pilot he spent years flying Hunter, Tiger F-5 and Mirage III jets, and he flies airliners for Swiss International Airlines.

He's spent several years developing the carbon fiber wing, which is eight feet long and features four German jet engines that provide 200 pounds of thrust. Rossy and his sponsors, which include the Swiss watch company Hublot, have spent $190,000 on the project, and with no plans to bring the wing to market, there's no guarantee they'll get a return on their investment.

The flight above the Alps was a big test for Fusionman and his wings, and it went off without a hitch. His mother wasn't even worried, explaining to the Associated Press, "He knows what he's doing."

But it hasn't always been smooth sailing -- er, flying -- for Rossy. Damage to a set of test wings in 2007 forced him to build another prototype, and he lost control during a jump three years ago and didn't deploy his chute until he was a mere 1,500 feet above the ground.

Soaring above the Alps is only the start. Rossy is planning to cross the English Channel -- a flight of about 23 miles -- by the end of the year. But his dream is to fly over the

St Louis

In an effort to encourage electronics recycling in St. Louis, local governments, community organizations and businesses in the city have launched “E-cycle St. Louis,” an initiative designed to develop ways to manage e-waste. According to an article in the St. Louis Post-Dispatch, the program, which is the first of its kind in the city, urges residents to recycle their electronic equipment at 10 sites throughout the city. Residents can bring obsolete items such as cell phones and computer monitors to the sites. In addition to the collection sites, educational materials and a Web site have been created to promote the program.
