Warming streams contribute to warming Chesapeake Bay
December 8, 2014 09:19 AM - US Geological Survey

The majority of streams in the Chesapeake Bay region are warming, and that increase appears to be driven largely by rising air temperatures. These findings are based on new U.S. Geological Survey research published in the journal Climatic Change.

Researchers found an overall warming trend in air temperature of 0.023 C (0.041 F) per year, and in water temperature of 0.028 C (0.050 F) per year over 51 years.  This means that air temperature has risen 1.1 C (1.98 F), and water temperature has risen 1.4 C (2.52 F) between 1960 and 2010 in the Chesapeake Bay region. 

O Christmas Tree, O Christmas Tree
December 3, 2014 10:18 AM - Allison Winter, ENN

The tradition of the Capitol Christmas Tree, or The People’s Tree, began in 1964 when Speaker of the U.S. House of Representatives John W. McCormack (D-MA) placed a live Christmas tree on the Capitol lawn. This tree lived three years before succumbing to wind and root damage. In 1970, the Capitol Architect asked the U.S. Forest Service to provide a Christmas tree. Since then, a different national forest has been chosen each year to provide The People’s Tree. This national forest also works with state forests to provide companion trees that are smaller Christmas trees for offices in Washington, D.C. 

 

This year, the 88-foot-tall white spruce tree was harvested from the Chippewa National Forest in northeastern Minnesota by Jim Scheff who won the Logger of the Year award from the Sustainable Forestry Initiative Inc. (SFI). 

 

That begs the question how can a logger win an award from a sustainability group? 

ENERGY STAR's first multifamily properties announced today
November 13, 2014 08:31 AM - ENERGY STAR

Roughly one-third of the U.S. population lives in the country’s 500,000 multifamily buildings, and they spend $22 billion on energy every year. Until this year, apartment and condo managers lacked the tools to measure how much energy they were wasting and compare their performance nationwide. Meanwhile, energy costs for renters have risen by 20 percent over the past decade.

 

Today, a new era of savings will be ushered in when the U.S EPA announces the first set of multifamily properties to earn the ENERGY STAR certification. The ENERGY STAR first became available to the sector this September, after a three-year partnership with Fannie Mae to develop the scoring system for multifamily properties.

The mysteries of what Comets actually are is getting closer to being solved
November 7, 2014 04:44 AM - Roger Greenway, ENN

Man has been amazed by comets for millenia. What are they, these beautiful wanderers?  There have been many theories, the most popular being that they are balls of ice.  Now we are actually getting data.  The photographs taken by the European Space Agency's Rosetta spacecraft show comet Churyumov-Gerasimenko to be more rocklike than a ball of ice. 

After sailing through space for more than 10 years, the Rosetta spacecraft is now less than a week shy of landing a robotic probe on a comet. 

The mission's Philae (fee-LAY) lander is scheduled to touch down on comet 67P/Churyumov-Gerasimenko on Wednesday, Nov. 12 at 7:35 a.m PST/10:35 a.m. EST. A signal confirming the landing is expected about 8:02 a.m. PST/11:02 a.m. EST. If all goes as planned with this complex engineering feat, it will be the first-ever soft landing of a spacecraft on a comet.

Good job: were using less water!
November 5, 2014 01:48 PM - U.S. Department of the Interior, U.S. Geological Survey

Water use across the country reached its lowest recorded level in nearly 45 years. According to a new USGS report, about 355 billion gallons of water per day (Bgal/d) were withdrawn for use in the entire United States during 2010.

This represents a 13 percent reduction of water use from 2005 when about 410 Bgal/d were withdrawn and the lowest level since before 1970.

“Reaching this 45-year low shows the positive trends in conservation that stem from improvements in water-use technologies and management,” said Mike Connor, deputy secretary of the Interior.  “Even as the U.S. population continues to grow, people are learning to be more water conscious and do their part to help sustain the limited freshwater resources in the country.”

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.
