Seafloor container ecology
May 8, 2014 09:54 AM - Monterey Bay Aquarium Research Institute Press Room
Thousands of shipping containers are lost from cargo vessels each year. Many of these containers eventually sink to the deep seafloor. In 2004, scientists at the Monterey Bay Aquarium Research Institute (MBARI) discovered a lost shipping container almost 1,300 meters (4,200 feet) below the surface of the Monterey Bay National Marine Sanctuary. In the first-ever survey of its kind, researchers from MBARI and the sanctuary recently described how deep-sea animal communities on and around the container differed from those in surrounding areas.
A dinosaur's evolution of the claw
May 7, 2014 11:02 AM - University of Bristol Newsroom
How did the evolution of the dinosaur claw evolve into the current bird form? A new University of Bristol study into the claws of a group of theropod dinosaurs, known as therizinosaurs, has revealed a great versatility in their usage. Theropod dinosaurs, a group that includes such famous species as Tyrannosaurus rex and Velociraptor, are often regarded as carnivorous and predatory animals, using their sharp teeth and claws to capture and dispatch prey. However, the detailed look at forelimb claws demonstrates that these claws were very likely to have been used for other tasks.
In search of safe drinking water
May 7, 2014 09:55 AM - Robin Blackstone, ENN
Access to safe drinking water is a fundamental requirement for good health and is also a human right. WHO and UNICEF’s indicator is based upon the "use of an improved source". The authors of a recent study into water contamination postulated that this did not account for water quality measurements or monitor global access to safe drinking water. Researchers Robert Bain and Jamie Bartram from The Water Institute at University of North Carolina sought to determine whether water from "improved" sources is less likely to contain fecal contamination than "unimproved" sources and to assess the extent to which contamination varies by source type and setting.
Scots are being encouraged to leave the car for journeys under two miles and enjoy the stress-relieving and health benefits of active travel, such as walking or cycling. Minister for Environment and Climate Change Paul Wheelhouse has launched the second phase of the national Active Travel campaign, confirming a further £250,000 for local authorities to promote the initiative.
Which Diamondback terrapin turtle is not like the others?
May 6, 2014 04:33 PM - Robin Blackstone, ENN
Until now little has been understood about the genetic variations of terrapin turtles. Terrapins have been designated a species of special concern in some areas and not in others. They are listed as an endangered species in Rhode Island and threatened in Massachusetts. Terrapins are the only North American turtle that spends its entire life in coastal marshes and mangroves.
With spring migration in full flight, a new report urges greater protection for an avian haven
May 5, 2014 10:18 AM - Guest Contributor, Lisa McCrummen
It's been dubbed North America's bird nursery: the sprawling billion-plus-acre boreal forest that spans the continent from Alaska across Canada to Newfoundland and Labrador. Each spring, an estimated 1 billion to 3 billion nesting birds make the long journey north to the boreal forest from wintering grounds throughout the United States and central and South America. Their populations swell during the boreal breeding season, and as many as 3 billion to 5 billion birds of remarkable diversity—from ring-necked ducks to whooping cranes to Cape May warblers to golden eagles—can make the return trip south in the fall. These are the birds that populate America's backyards, parks, and wetlands, providing enjoyment and recreation to millions of birders, conservationists, and waterfowl hunters.
Bicycles Can Change the World
May 4, 2014 09:22 AM - Anna Brones, Care2
Saying that bicycles can change the world might sound like an oversimplification of things, but when you start to break it down, it’s easy to see that the bicycle has an effect on a lot more than just how we get from point A to point B. Need proof for why bicycles are a good way to change the world? Here are some good ones. 1. They provide alternative transportation It doesn’t take a scientist to work out that switching from four wheels to two wheels is a good thing. First there’s the environmental reason. For example, if 5 percent of people in New York commuting by car (either private or taxi) were to bike to work, they could save 150 million pounds of CO2 emissions per year. That’s the equivalent to the amount of CO2 reduced by planting a forest 1.3 times the size of Manhattan. And that’s only with a 5 percent change.
Is an Electric Car Right for You?
May 3, 2014 09:52 AM - CLEANTECHIES GUEST AUTHOR, Clean Techies
Operating a car without needing to visit a gas station is intriguing idea to many American drivers. After all, the pumps can be a painful place—gas prices have been on a roller coaster ride the past few years. But in the minds of many American, electric cars are nothing more than glorified golf cars incapable of providing adequate daily driving range or sufficient highway speed. In this new era of electrified transportation, those misconceptions need to be tossed aside. Todays' electric vehicles, like the Nissan Leaf, provide all the creature comforts and capabilities of gasoline internal combustion cars. These EVs comfortably seat four or five passengers, offer quasi-luxury features, and serve up smooth, silent and sporty levels of acceleration. But there are a couple of important issues to consider—such as driving range and refueling times.
"Close the door to landfilling." says the European Commission's Director-General for Environment

In a passionate call for change, Karl Falkenberg, European Commission Director-General for Environment calls for a closure of landfilling, as we know it. "Separate collection is very much at the heart of this circular economy - [but] we are coming to realize that separate collection is not enough," said Falkenberg, the at a conference in Brussels on Tuesday (29 April).
Local residents chronicle lake water quality
May 2, 2014 10:29 AM - Robin Blackstone, ENN
Long-term water quality trends in Midwestern lakes yield good news in the form of little change in water clarity in the regions 3,000 lakes. But what makes this news unique is that the data to make this determination was collected by non-scientists and local residents from the area’s towns and villages.
