A University of Texas at El Paso (UTEP) study on children’s health has found that fourth and fifth graders who are exposed to toxic air pollutants at home are more likely to have lower GPAs.
A new international study is the first to use a high-resolution, large-scale computer model to estimate how much ice the West Antarctic Ice Sheet could lose over the next couple of centuries, and how much that could add to sea-level rise. The results paint a clearer picture of West Antarctica’s future than was previously possible. The study has been published in The Cryosphere, an open access journal of the European Geosciences Union (EGU).
“The IPCC’s [Intergovernmental Panel on Climate Change] 4th and 5th Assessment Reports both note that the acceleration of West Antarctic ice streams in response to ocean warming could result in a major contribution to sea-level rise, but that models were unable to satisfactorily quantify that response,” says Stephen Cornford, a research assistant at the University of Bristol, UK and lead-author of the study.
Each spring, powerful dust storms in the deserts of Mongolia and northern China send thick clouds of particles into the atmosphere. Eastward winds sweep these particles as far as the Pacific, where dust ultimately settles in the open ocean. This desert dust contains, among other minerals, iron — an essential nutrient for hundreds of species of phytoplankton that make up the ocean’s food base.
Global sea levels have risen nearly 3 inches in less than 25 years, with some locations around the world rising more than 9 inches, according to NASA’s latest satellite data. An intensive research effort now underway, aided by NASA observations and analysis, points to an unavoidable rise of several feet in the future.
At the end of November, governments will come together in Paris to hammer out agreements for a successor to the Kyoto Protocol. Under the KP, there are two greenhouse gas (GHG) emissions offsetting mechanisms: joint implementation (JI) and the Clean Development Mechanism (CDM).
JI allows countries with emissions-reduction commitments under the Kyoto Protocol to generate Emission Reduction Units (ERUs) from GHG reduction projects and transfer them to other countries. Almost 872 million ERUs had been issued under JI as of March 2015, about a third of all Kyoto offset credits. In a nutshell, JIs are carbon credits and include things like reforestation projects.
"If I offered you a bruised banana, you probably wouldn’t be interested,” said Jonathan Deutsch, PhD, director of Drexel University’s Center for Hospitality and Sport Management. “But what if I offered you some banana ice cream on a hot summer day? I bet you’d find that a lot more appealing.”
It was this simple observation that inspired a new model for recovering would-be wasted – or surplus – food and repurposing it to feed hungry people, generate revenue and even create jobs. The model was recently piloted in West Philadelphia, home to a large population of low-income and food insecure individuals, as part of the Environmental Protection Agency’s Food Recovery Challenge with support from Brown’s Super Stores.
Compiled by researchers from Drexel University, University of Pennsylvania, Cabrini College and the EPA, the results were published in Food and Nutrition Sciences, a peer-reviewed international journal dedicated to the latest advancements in food and nutrition sciences. The report also projects the amount of food that could be saved if the program was replicated nationally.
Everyday cosmetic and cleaning products contain huge quantities of plastic particles, which are released to the environment and could be harmful to marine life, according to a new study. Research at Plymouth University has shown almost 100,000 tiny ‘microbeads’ – each a fraction of a millimetre in diameter – could be released in every single application of certain products, such as facial scrubs.
Individuals previously diagnosed with heart disease may be less likely to experience heart failure, heart attacks, or stroke, or to die from these events, if they have higher blood levels of two very closely related proteins, according to a new study led by a UC San Francisco research team.
One of these proteins, known as GDF11, has attracted great interest since 2013, when researchers showed that it could rejuvenate old mice. Based on these findings, scientists have speculated that drugs that increase GDF11 levels might reverse physiological manifestations of aging that lead to heart failure in people.
Men and persons age 65 and older who have access to natural surroundings, whether it’s the green space of a nearby park or a sandy beach and an ocean view, report sleeping better, according to a new University of Illinois study published in Preventive Medicine.
In addition to melting icecaps and imperiled wildlife, a significant concern among scientists is that higher Arctic temperatures brought about by climate change could result in the release of massive amounts of carbon locked in the region’s frozen soil in the form of carbon dioxide and methane. However, new research led by Princeton University researchers and published in The ISME Journal in August suggests that, thanks to methane-hungry bacteria, the majority of Arctic soil might actually be able to absorb methane from the atmosphere rather than release it.
