Wooly Mammoths and Mastodons loved Cincinnati!
July 22, 2014 04:47 PM - University of Cincinnati via ScienceDaily

Their scruffy beards weren't ironic, but there are reasons mammoths and mastodons could have been the hipsters of the Ice Age. According to research from the University of Cincinnati, the famously fuzzy relatives of elephants liked living in Greater Cincinnati long before it was trendy -- at the end of the last ice age. A study led by Brooke Crowley, an assistant professor of geology and anthropology, shows the ancient proboscideans enjoyed the area so much they likely were year-round residents and not nomadic migrants as previously thought.

New research compares environmental costs of livestock-based foods
July 22, 2014 08:00 AM - Allison Winter, ENN

Trust me, no one loves a nice, big, juicy steak more than me and while I have no immediate plans of becoming a vegetarian, I am a little concerned about the resources and costs it takes to produce the proteins of our favorite meals. From the land that is used by livestock to the supplies and energy it takes to raise these animals for our consumption, it is evident that environmental resources take a toll. But what is the real cost? New research at the Weizmann Institute of Science, conducted in collaboration with scientists in the US, calculates these environmental costs and compares various animal proteins to give a multi-perspective picture of what resources are really being used.

Devil Rays are deep divers!
July 21, 2014 03:23 PM - Woods Hole Oceanographic Institution

Thought to dwell mostly near the ocean's surface, Chilean devil rays (Mobula tarapacana) are most often seen gliding through shallow, warm waters. But a new study by scientists at Woods Hole Oceanographic Institution (WHOI) and international colleagues reveals that these large and majestic creatures are actually among the deepest-diving ocean animals. "So little is known about these rays," said Simon Thorrold, a biologist at WHOI and one of the authors of the paper, published July 1, 2014, in the journal Nature Communications. "We thought they probably travelled long distances horizontally, but we had no idea that they were diving so deep. That was truly a surprise."

The mystery behind starling flocks explained
July 18, 2014 11:51 AM - University of Warwick

The mystery behind the movements of flocking starlings could be explained by the areas of light and dark created as they fly, new research suggests. The research, conducted by the University of Warwick and published in the journal PNAS, found that flocking starlings aim to maintain an optimum density at which they can gather data on their surroundings. This occurs when they can see light through the flock at many angles, a state known as marginal opacity. The subsequent pattern of light and dark, formed as the birds attempt to achieve the necessary density, is what provides vital information to individual birds within the flock.

New Insect Repellent Graphic Released by EPA
July 17, 2014 04:15 PM - US EPA Newsroom

The U.S. Environmental Protection Agency today unveiled a new graphic that will be available to appear on insect repellent product labels. The graphic will show consumers how many hours a product will repel mosquitoes and/or ticks when used as directed. "We are working to create a system that does for bug repellents what SPF labeling did for sunscreens," said Jim Jones, Assistant Administrator of the Office of Chemical Safety and Pollution Prevention. "By providing vital information to consumers, this new graphic will help parents, hikers and the general public better protect themselves and their families from serious health threats caused by mosquitoes and ticks. We are encouraging manufacturers to submit applications so they can add the graphic to their registered repellent products."

Fertilizer Threatens Grasslands Globally
July 15, 2014 05:10 PM - Paul Sutherland, MONGABAY.COM

The world's grasslands are being destabilized by fertilization, according to a paper recently published in the journal Nature. In a study of 41 grassland communities on five continents, researchers found that the presence of fertilizer weakened grassland species diversity. The researchers surveyed grasslands in countries around the world, such as China, the U.S., Switzerland, Tanzania and Germany, and discovered that grassland communities that had not been managed by humans contained more species. They also had greater species asynchrony, which means that different species thrive at different times so that the grassland produces more consistently over time, resulting in more stable biomass production.

Scalloped Hammerhead Sharks officially endangered, and that is not good news!
July 14, 2014 04:49 PM - s.e. smith, Care2, Care2

It’s not really the kind of "first" you want to be: The peculiar-looking but oddly beautiful scalloped hammerhead shark has just become the first shark species to be added to the US Endangered Species List. Sphyrna lewini, as they're known, are coastal to semi-oceanic sharks with a number of extremely vulnerable subpopulations. The move to classify them as endangered is in response to lobbying from several animal welfare groups who hoped to secure additional protections for these amazing creatures before it's too late.

Pesticide impairs bees' ability to forage
July 14, 2014 09:11 AM - ClickGreen Staff, ClickGreen

A study that involved fitting bumblebees with tiny radio frequency tags found long-term exposure to a neonicotinoid pesticide hampers bees' ability to forage for pollen. The research by Nigel Raine, a professor at the University of Guelph, and Richard Gill of Imperial College, London, shows how long-term pesticide exposure affects individual bees' day-to-day behaviour, including pollen collection and which flowers worker bees chose to visit.

Our newest Astronauts are fruit flies!
July 10, 2014 06:15 AM - Roger Greenway, ENN

Becoming an Astronaut is a big deal! Men and women selected to go into space are very carefully chosen. They go through rigorous medical evaluations to make sure they are healthy and that their bodies can withstand the forces of liftoff and re-entry. And they go through months and months of training to prepare them for their first space flight. Now NASA is sending untested, untrained astronauts into space. Of course, they are not human, they are fruit flies! Fruit flies are bug eyed and spindly, they love rotten bananas, and, following orders from their pin-sized brains, they can lay hundreds of eggs every day. We have a lot in common. Genetically speaking, people and fruit flies are surprisingly alike, explains biologist Sharmila Bhattacharya of NASA's Ames Research Center. "About 77% of known human disease genes have a recognizable match in the genetic code of fruit flies, and 50% of fly protein sequences have mammalian analogues."

Cell Phone Conservation
July 9, 2014 10:35 AM - Alex Kirby, The Ecologist

Some of the world's most endangered forests may soon benefit from better protection, thanks to discarded treasures from the consumer society - mobile phones. A Californian technology startup, Rainforest Connection (RFCx), has developed a tool - made from recycled smartphones - that it says will pilot new ways to monitor and stop illegal logging and animal poaching throughout Africa's equatorial forests. RFCx has formed a partnership with the Zoological Society of London (ZSL), an international scientific charity that works for the worldwide conservation of animals and their habitats. The two organisations are planning to install the anti-deforestation, anti-poaching technology in Cameroon this year.
