The prevalence of naturally occurring asbestos in the environment
November 4, 2014 10:49 AM - Geological Society of America, via EurekAlert.

Naturally occurring asbestos minerals may be more widespread than previously thought, with newly discovered sources now identified within the Las Vegas metropolitan area. The asbestos-rich areas are in locations not previously considered to be at risk, according to new report that will be presented at the Annual Meeting of the Geological Society of America (GSA) in Vancouver, Canada, on Sunday, 20 October.

"These minerals were found where one wouldn't expect or think to look," said Rodney Metcalf, associate professor of geology at the University of Nevada, Las Vegas, and co-researcher of the study. The naturally occurring asbestos was found in Boulder City, Nevada, in the path of a construction zone to build a multi-million dollar highway called the Boulder City Bypass, the first stage of an I-11 corridor planned between Las Vegas and Arizona.

MIT finds switching to higher octane fuel would reduce carbon emissions
October 28, 2014 07:15 AM - MIT News

If the majority of light-duty vehicles in the United States ran on higher-octane gasoline, the automotive industry as a whole would reduce its carbon dioxide emissions by 35 million tons per year, saving up to $6 billion in fuel costs, according to a new analysis by MIT researchers.

 

In a study published in the journal Environmental Science & Technology, the team considered a scenario in which fuel is manufactured under a redefined octane rating — the measure of a gasoline’s ability to resist engine knocking during combustion.

Ebola - vaccines under development show promise
October 27, 2014 06:48 AM - International Union of Immunological Societies, via EurekAlert.

Not everyone who contracts the Ebola virus dies, the survival rate is around 30% suggesting that some kind of immunity to the disease is possible. Experimental treatments and vaccines against Ebola exist but have not yet been tested in large groups for safety and efficacy (phase 2 trials). 

The International Union of Immunology Societies (IUIS) published a statement today in its official journal, Frontiers in Immunology calling for urgent and adequate funding of vaccine candidates in clinical trials and speedy implementation of immunisation in African countries.

Abundant natural gas will not slow climate change according to new study
October 16, 2014 06:22 AM - Pacific Northwest National Laboratory

A new analysis of global energy use, economics and the climate shows that without new climate policies, expanding the current bounty of inexpensive natural gas alone would not slow the growth of global greenhouse gas emissions worldwide over the long term, according to a study appearing today in Nature Advanced Online Publication. Because natural gas emits half the carbon dioxide of coal, many people hoped the recent natural gas boom could help slow climate change — and according to government analyses, natural gas did contribute partially to a decline in U.S. carbon dioxide emissions between 2007 and 2012.

Methane sink discovered in oceanic rock
October 15, 2014 06:35 AM - Oregon State University

Since the first undersea methane seep was discovered 30 years ago, scientists have meticulously analyzed and measured how microbes in the seafloor sediments consume the greenhouse gas methane as part of understanding how the Earth works. The sediment-based microbes form an important methane "sink," preventing much of the chemical from reaching the atmosphere and contributing to greenhouse gas accumulation. As a byproduct of this process, the microbes create a type of rock known as authigenic carbonate, which while interesting to scientists was not thought to be involved in the processing of methane.

Does the public trust what scientists say?
October 6, 2014 03:58 PM - Princeton University

If scientists want the public to trust their research suggestions, they may want to appear a bit "warmer," according to a new review published by Princeton University's Woodrow Wilson School of Public and International Affairs. The review, published in the Proceedings of the National Academy of Sciences (PNAS), shows that while Americans view scientists as competent, they are not entirely trusted. This may be because they are not perceived to be friendly or warm.

Lawrence Livermore finds ocean warming underestimated by past analyses
October 6, 2014 07:32 AM - Anne M Stark, LLNL

Using satellite observations and a large suite of climate models, Lawrence Livermore scientists have found that long-term ocean warming in the upper 700 meters of Southern Hemisphere oceans has likely been underestimated. "This underestimation is a result of poor sampling prior to the last decade and limitations of the analysis methods that conservatively estimated temperature changes in data-€sparse regions," said LLNL oceanographer Paul Durack, lead author of a paper appearing in the October 5 issue of the journal Nature Climate Change.

New MIT report predicts serious future warming
September 30, 2014 07:38 AM - Audrey Resutek | MIT Joint Program on the Science and Policy of Global Change

Global temperature is likely to rise 3.3-5.6 degrees Celsius by the end of this century, unless international climate negotiations in Paris next year are more effective than expected, according to a report released Monday by the MIT Joint Program on the Science and Policy of Global Change. The predicted temperature increase surpasses the threshold identified by the United Nations as necessary to avoid the most serious impacts of climate change, altering precipitation patterns and heightening the pressures of population and economic growth. "Our world is rapidly changing," says John Reilly, co-director of the MIT Joint Program and a coauthor of the report. "We need to understand the nature of the risks we’re facing so we can prepare for them."
