  • Cross-species animal fights explained by new research
    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
    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
    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?
    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
    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
    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...
    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.
