Monitoring a wound as it heals should get easier thanks to a new kind of optical fiber that could become a part of everyday bandages. The fiber’s coating alters in color in response to changes in acidity, a key health indicator in wounds. The core of the fiber carries light to and from an attached device, which caregivers could use to monitor a wound in real time, says Bastien Schyrr, a Ph.D. student in biomedical engineering at the University of Fribourg, in Switzerland, who last month presented results of a laboratory trial in which the enhanced bandage detected acidity changes in a solution containing human serum.

Matching Scientists with Adventurers
Gregg Treinish, a man whose hiking credentials include a stroll along most of the Andes, took part in the Appalachian Trail Days event last weekend with an unusual sense of purpose. On a previous hike, he “felt selfish and … realized that was a shared feeling amongst hikers and mountaineers,” Treinish says. That feeling, together with a stint studying wildlife biology at Montana State University, gave him an original idea: to offer adventurers the opportunity to share with scientists something that even those who travel light routinely take with them on their adventures: their eyes and ears. Now, wherever he goes, Treinish recruits fellow adventurers for his new organization, Adventurers and Scientists for Conservation (ASC). Continue reading Matching Scientists with Adventurers
Swiss Scientists Design a Turbine to Fit in Human Arteries
Coaches admire athletes for showing a lot of heart, and poets praise the organ’s passions, but engineers see the human cardiovascular system otherwise. The heart is a pump in a prime location, brimming with energy for the taking, says biomedical engineer Alois Pfenniger. So together with colleagues at the University of Bern and the Bern University of Applied Sciences, in Switzerland, Pfenniger has tested small turbines designed to fit inside a human artery, like an implantable hydroelectric generator.

Australian Government Silent on Synchrotron Budget While Scientists Plan Expansion
One might think that the managers of the Australian Synchrotron would be panicking given the news that neither the federal government nor the Victoria state government has addressed in their just-released budget proposals how the facility will be funded beyond June 2012, when its original 5-year financial plan ends. After all, the two governments currently provide most of the synchrotron’s annual funding. Yet, at least publicly, those running the synchrotron are thinking not about how to save the young facility but how to grow it. “We are now in the process of wanting to expand,” says Andrew Peele, a physicist at La Trobe University in Victoria who has been head of science at the synchrotron since late last year.
