As many of us once again rouse ourselves from festivities filled with an overabundance of food, it might be sombering to ponder that a recent PLoS ONE study suggests that nearly 40 percent of food in the United States is wasted.  As noted in a recent ScienceNOW article, physiologist Kevin Hall and mathematician Carson Chow, both at the National Institute…

 Most people schussing down a ski slope probably don’t wonder if it’s been cleared or graded and why the answer makes a big difference to the surrounding environment.  A new study out in December’s Ecological Applications finds that there is a big difference between a downhill ski slope that’s been cleared (cutting and removing shrubs and trees) versus one that…

This post was contributed by Meg Lowman, ESA Vice President for Education and Human Resources, who just recently returned from the Copenhagen climate summit.  With good intentions, delegates arrived from 192 nations in Copenhagen, Denmark last week for the UNFCCC (United Nations Framework for Climate Change Convention). Their goal was to meet, talk, draft, edit and finalize a document to…

This post was contributed by Piper Corp, ESA Science Policy Analyst.  Pope Benedict XVI has received his share of criticism from the scientific community, most recently because of his statement that condoms increase the risk of HIV transmission.  But in his December 15 message for the Catholic Church’s annual World Day of Peace, he gave ecological scientists and environmentalists something…

Lyme disease (Borrelia burgdorferi) is typically associated with mammals, but birds too can become infected by black-legged ticks (Ixodes scapularis), the principal vector of the pathogen.  Moreover, birds may figure significantly in the range expansion of both the Lyme bacterium and black-legged ticks.  So say Jory Brinkerhoff and colleagues of Yale University in a paper published today in Frontiers in…

The human industrial and agricultural sectors contribute to air pollution by releasing nitrogen oxides (sometimes denoted NOx) into the atmosphere. And just like ocean acidification occurs when carbon dioxide dissolves into the ocean, soil acidification can occur when nitrogen oxides dissolve into soils. But we also know that nitrogen is a major component of fertilizers, which add nutrients to soils. …

Next year, the US Navy will enlist as many as 20 bottle-nosed dolphins and California sea lions to provide around-the-clock surveillance of Naval Base Kitsap-Bangor in Washington State. The new recruits have been trained through the Navy Marine Mammal Program (NMMP) to locate and apprehend swimmers and divers in…

Biofuels hold promise for reducing the world’s consumption of unsustainable fossil fuels.  But like any new technology, they come with their own host of issues and problems.  One such problem is the so-called “indirect” effect of biofuels on the landscape and the atmosphere. For example, when farmlands are converted to biofuel crops, the food formerly grown on those lands needs…

COPENHAGEN NEGOTIATIONS The December climate summit commenced today.  Of chief concern to the international community are numbers on the following two matters: 1) Near-term emissions reduction: President Obama recently pledged that the US will reduce emissions “in…

Open access to scientific journals is a contentious issue in the sciences. A recent article in the (open-access) journal PLoS Biology makes the case that open access is the way of the future and is good for science, scientists and universities alike. In his essay, David Shulenburger of the Association of Public and Land-Grant Universities says that limiting access to…
