How to help your brain age more slowly
April 25, 2015 08:16 AM - Laura Kurtzman, University of California San Francisco

Brains age, just like the rest of the body, even for those don't get neurological disease, according to an Institute of Medicine.

"Some of the changes that one observes doesn't mean that it's all over, gloom and doom," the committee’s vice chair, Kristine Yaffe, MD, told the Washington Post.

”‹While aging does more damage to some than others, most people can take steps to improve their health, according to Yaffe, the Roy and Marie Scola Endowed Chair and professor of psychiatry, neurology, and epidemiology at UCSF and chief of geriatric psychiatry and director of the Memory Disorders Clinic at the San Francisco VA Medical Center.

Mountains warming faster than expected
April 24, 2015 03:28 PM - Janet Lathrop, UMassAmherst

High elevation environments around the world may be warming much faster than previously thought, according to members of an international research team including Raymond Bradley, director of the Climate System Research Center at the University of Massachusetts Amherst. They call for more aggressive monitoring of temperature changes in mountain regions and more attention to the potential consequences of warming.

What's worse for polar bears- Global Warming or Pollution?
April 24, 2015 02:44 PM - Tim Radford, The Ecologist

As if melting ice in Polar bears' Arctic habitat was not enough, Norwegian scientists have found that organic pollutants such as pesticide residues are disrupting their thyroid and endocrine systems, adding a further threat to the species' survival.

Cross-species animal fights explained by new research
April 24, 2015 07:54 AM - UNIVERSITY OF CALIFORNIA - LOS ANGELES via EurekAlert

Why do animals fight with members of other species? A nine-year study by UCLA biologists says the reason often has to do with "obtaining priority access to females" in the area.

The scientists observed and analyzed the behavior of several species of Hetaerina damselflies, also known as rubyspot damselflies. For the study, published this month in the print edition of the journal Proceedings of the Royal Society B, researchers observed more than 100 damselflies a day in their natural habitat along rivers and streams in Texas, Arizona and Mexico.

Microbes have major effect on climate change
April 24, 2015 07:21 AM - Kathleen Haughney, Florida State University

Carbon, held in frozen permafrost soils for tens of thousands of years, is being released as Arctic regions of the Earth warm and is further fueling global climate change, according to a Florida State University researcher.

Cleaner buses could result in fewer school absences
April 23, 2015 12:32 PM - ClickGreen Staff, ClickGreen

The use of clean fuels and updated pollution control measures in the school buses 25 million children ride every day in the United States could result in 14 million fewer absences from school a year, based on a study by the University of Michigan and the University of Washington. In research believed to be the first to measure the individual impact on children of the federal mandate to reduce diesel emissions, researchers found improved health and less absenteeism, especially among asthmatic children.

What countries have the most endangered animals?
April 23, 2015 10:55 AM - Susan Bird, Care2

If you had to guess which countries are losing the greatest number of endangered mammals to extinction, which would you pick? Actually, you don’t have to guess. There’s a new map that will show you, in no uncertain terms, where in the world we’re losing animals the fastest. The top three “winners” of this unfortunate contest are Indonesia (184), Madagascar (114), Mexico (101), with India following close behind at 94.

Putting a value on our Oceans
April 23, 2015 06:56 AM - World Wildlife Fund, Justmeans

The ocean’s wealth rivals those of the world’s leading economies, but its resources are rapidly eroding, according to a new World Wildlife Fund (WWF) report. The analysis, Reviving the Ocean Economy: The Case for Action, conservatively estimates the value of key ocean assets to be at least $24 trillion. If compared to the world’s top 10 economies, the ocean would rank as the seventh largest, with an annual value of goods and services of $2.5 trillion.

The report, produced in association with The Global Change Institute at the University of Queensland and The Boston Consulting Group (BCG), combines scientific evidence of environmental degradation with an economic case for urgent conservation action. Using an innovative economic analysis, the ocean’s value is quantified based on assessments of goods and services ranging from fisheries to coastal storm protection, resulting in an overall asset value and an annual dividend output (comparable to a GDP).

A brief history of Earth Day
April 22, 2015 09:59 PM - Earth Day Network

Each year, Earth Day -- April 22 -- marks the anniversary of what many consider the birth of the modern environmental movement in 1970.

The height of hippie and flower-child culture in the United States, 1970 brought the death of Jimi Hendrix, the last Beatles album, and Simon & Garfunkel’s “Bridge Over Troubled Water”. Protest was the order of the day, but saving the planet was not the cause. War raged in Vietnam, and students nationwide increasingly opposed it.

 

On Earth Day, Give Fiber Its Due...
April 22, 2015 02:14 PM - Guest Contributor, James Gowen, Verizon Chief Sustainability Officer

There's a touch of green associated with receiving phone service, using the Internet and streaming video over an all-fiber-optic network. It's not the color of laser-generated light that carries massive amounts of data through all-glass cables directly into homes and businesses. It's green in the sense of how much more environmentally friendly today’s fiber-based telecommunications networks are compared to copper wire and coaxial cable networks. Whether it's energy efficiency or reduced demand for raw materials and other resources, all-fiber networks are a winning strategy on many fronts — including environmental sustainability. As we approach the 45th celebration of Earth Day on April 22, it's a good time to reflect on how network and technology decisions made by major telecommunications companies don't just result in advanced, more reliable services. These decisions can also pay handsome dividends on the sustainability front.
