Nine percent of the Western Hemisphere’s mammals—and up to 40 percent in some regions—may not be able to outpace climate change. “I think it’s important to point out that in the past when climates have changed—between glacial and interglacial periods when species ranges contracted and expanded—the landscape wasn’t covered with agricultural fields, four-lane highways and parking lots, so species could move much more freely across the landscape,” says Joshua Lawler, associate professor of environmental and forest sciences at University of…

Time of year matters for vitamin D risk
16 May 2012 | 12:08 pmWhen considering a patient’s blood vitamin D levels, it may be best to consider a lower threshold for concern, as well as the time of year. "In evaluating health risk," the University of Washington researchers conclude, "season-specific targets for Vitamin D blood concentration may be more appropriate than a static target when evaluating patients health risk."

The mechanics of eclipses [infographic]
16 May 2012 | 9:11 amWhen the moon passes in front of sun, as viewed from Earth, the eclipse that occurs is visible from a narrow path on Earth that corresponds to the location of the moon's shadow. During a total solar eclipse, this path is known as the path of totality. WARNING: Never look directly at the sun during an eclipse with a telescope or your unaided eye. Severe eye damage can result and scientists use special filters to safely view the sun. Via Space. The view from space. Permalink | Leave a comment » -
Clean air improves heart health, Olympics show
16 May 2012 | 8:39 amUsing the 2008 Beijing Olympics as a lab, researchers found evidence that even short-term reduction in air pollution exposure improves a person’s cardiovascular health. “Beijing is one of the most polluted cities in the world, and the Chinese government had proposed to reduce pollution levels to be comparable to other Olympic host cities,” says USC Professor Junfeng (Jim) Zhang. “We wanted to take advantage of such a huge intervention and look at what happens to people biologically.” Full story at Futurity.
