EAST LANSING, Mich. — Using nature’s beauty as a tourist draw can boost conservation in China’s valued panda preserves, but it isn’t an automatic ticket out of poverty for the human inhabitants, a long-term study at Michigan State University shows.
The policy hitch: Often those who benefit most from nature-based tourism endeavors are people who already have resources. The truly impoverished have a harder time breaking into the tourism business. (more…)
In the fight against emerging public health threats, early diagnosis of infectious diseases is crucial. And in poor and remote areas of the globe where conventional medical tools like microscopes and cytometers are unavailable, rapid diagnostic tests, or RDTs, are helping to make disease screening quicker and simpler.(more…)
COLUMBUS, Ohio – Scientists have found why a certain type of bacteria, harmless in healthy people, is so deadly to patients with cystic fibrosis.
The bacterium, Burkholderia cenocepacia, causes a severe and persistent lung infection in patients with CF and is resistant to nearly all known antibiotics. Cystic fibrosis is a chronic disorder characterized by a buildup of mucus in the lungs and other parts of the body, and various types of lung infection are responsible for about 85 percent of deaths in these patients.

The most transparent, lightweight and flexible material ever for conducting electricity has been invented by a team from the University of Exeter.
Called GraphExeter, the material could revolutionise the creation of wearable electronic devices, such as clothing containing computers, phones and MP3 players.
GraphExeter could also be used for the creation of ‘smart’ mirrors or windows, with computerised interactive features. Since this material is also transparent over a wide light spectrum, it could enhance by more than 30% the efficiency of solar panels.
Adapted from graphene, GraphExeter is much more flexible than indium tin oxide (ITO), the main conductive material currently used in electronics. ITO is becoming increasingly expensive and is a finite resource, expected to run out in 2017. (more…)

Life-changing opportunities made possible by donor’s generosity
From working on solar-powered energy in India and conducting historic research on the Jewish community of Buenos Aires, to studying the world parrot crisis and examining music and dance in Bali, the four 2011 Plastino Scholars recounted their experiences at a dinner on Thursday, April 26, that celebrated their experiences and welcomed the incoming 2012 cohort.(more…)
PASADENA, Calif. — While some galaxies are rotund and others are slender disks like our spiral Milky Way, new observations from NASA’s Spitzer Space Telescope show that the Sombrero galaxy is both. The galaxy, which is a round elliptical galaxy with a thin disk embedded inside, is one of the first known to exhibit characteristics of the two different types. The findings will lead to a better understanding of galaxy evolution, a topic still poorly understood.
“The Sombrero is more complex than previously thought,” said Dimitri Gadotti of the European Southern Observatory in Chile and lead author of a new paper on the findings appearing in the Monthly Notices of the Royal Astronomical Society. “The only way to understand all we know about this galaxy is to think of it as two galaxies, one inside the other.”(more…)
Clogging of pipes leading to the heart is the planet’s number one killer. Surgeons can act as medical plumbers to repair some blockages, but we don’t fully understand how this living organ deteriorates or repairs itself over time.
Researchers at the University of Washington have studied vessel walls and found the cells pull more tightly together, reducing vascular leakage, in areas of fast-flowing blood. The finding could influence how doctors design drugs to treat high cholesterol, or how cardiac surgeons plan their procedures. (more…)
