Editor's note: Our profile of Bill Nye [September 2014] elicited an impassioned response from readers. We received more than 100 letters, many from readers grappling with how to reconcile scientific concepts like climate change with religion. We asked climate scientist Katharine Hayhoe, an evangelical Christian, why science doesn't have to conflict with faith. (We wrote about Dr. Hayhoe previously in July.) Popular Science does not necessarily support or endorse the views expressed here. The text has been edited for grammar and style.
Cryan's research, published today in Proceedings of the National Academy of Sciences, found that certain species of tree-roosting bats are more likely to be killed by wind turbines when the blades are moving at low speeds. By tracking the bats with thermal surveillance cameras, near-infrared video, acoustic detectors, and radar, the researchers discovered that bats tend to approach turbines from downwind, particularly when the turbines spin slowly relative to the wind speeds around them. This led researchers to theorize that the wind currents around slow moving turbines may resemble those created by trees, where the bats gather to roost and hunt insects.
Much of the American Southwest has been in drought conditions for more than a decade—harsher in some places than the dry spell that caused the Dust Bowl of the 1930's. Until recently, however, California had largely been spared. That changed when an air mass dubbed the Ridiculously Resilient Ridge appeared over the Pacific in the winter of 2013—an event Daniel Swain, lead author on the study and weather blogger, says is likely the result of human activity.
The dusty hills around Lima sprout concrete at all angles. There are many words here for the gray delineation of poverty-struck areas: áreas tugurizadas (slum zones), the less formal tugurios (projects), solares (tenements), barriadas asistidas (assisted shanty towns). The average shanty-town income is less than $150 a month, which makes it a difficult place to conduct public health campaigns. In the 1990s, Dr. Jim Yong Kim, now the president of the World Bank, worked with the non-profit Partners in Health (PIH) to identify and then control an epidemic of multiple-drug-resistant tuberculosis in Lima. Kim called it “Ebola with wings.”
As the Ebola outbreak continues to spread throughout West Africa, one thing is on everyone’s minds: finding a cure. But while many researchers are toiling away, trying to fulfill this desperate need, others are trying to capitalize on it. Various companies are claiming to have treatments that can cure or prevent Ebola, and those treatments can be yours! For a fee, of course.
