Why Elephants Rarely Get Cancer
October 8, 2015 12:58 PM - University of Utah
Why elephants rarely get cancer is a mystery that has stumped scientists for decades. A study led by researchers at Huntsman Cancer Institute (HCI) at the University of Utah and Arizona State University, and including researchers from the Ringling Bros. Center for Elephant Conservation, may have found the answer.
Chernobyl considered unlikely nature reserve for some species
October 8, 2015 08:47 AM - Steve Williams, Care2
When you think of Chernobyl you probably think along the lines of “nuclear disaster” and a “no-go” area, but new research shows that with humans now absent from the region, several mammal species including wild boar and wolves, are increasing in number in this most unlikely nature reserve.
Arctic butterflies adapt to warming climate by getting smaller

New research shows that butterflies in Greenland have become smaller in response to increasing temperatures due to climate change.
It has often been demonstrated that the ongoing rapid climate change in the Arctic region is causing substantial change to Arctic ecosystems. Now Danish researchers demonstrate that a warmer Greenland could be bad for its butterflies, becoming smaller under warmer summers.
Researchers trace how birds, fish go with the flow
October 6, 2015 09:16 AM - New York University
Fish and birds, when moving in groups, could use two “gears”—one slow and another fast—in ways that conserve energy, a team of New York University researchers has concluded. Its findings offer new insights into the contours of air and water flows--knowledge that could be used to develop more energy-efficient modes of transportation.
Are fish the greatest athletes?

When you think of the world’s greatest athletes, names like Usain Bolt generally spring to mind, but scientists have discovered the best athletes could well be found in the water, covered in scales.
It turns out that fish are far more effective at delivering oxygen throughout their body than almost any other animal, giving them the athletic edge over other species.
Noise pollution harms wildlife, degrades habitats

Traffic noise is just another inconvenience for many of us. But for wildlife, noise from honking, and zooming vehicles can often be an insidious threat: it can degrade habitats without leaving any physical evidence of change, warns a recent study published in the Proceedings of the National Academy of Sciences.
Road noise — even in moderate levels — pushes migrating birds away from their stopover habitats, researchers from Boise State University in Idaho found. Those that stay back become weak.
“I was initially surprised that even moderate road noise — comparable to a suburban setting — would have such a wide-ranging impact on migrating birds,” William Laurance, a professor at James Cook University in Cairns, Australia, who was not involved in the study, told Mongabay. “On reflection, however, I guess such migrators have to be hyper-vigilent about noise, as they’re constantly moving to new areas where unseen predators could be lurking.”
Could Mealworms Help Solve our Styrofoam Waste Problem?
October 2, 2015 03:16 PM - Kevin Mathews, Care2
Plastic waste is out of control in this country, and Styrofoam is one of the worst offenders. Americans toss out 25 billion Styrofoam cups each year. Over two million tons of the stuff ends up in landfills, where it does not biodegrade. Scientists think they may have found a solution for our Styrofoam problem, though: feed it to the worms!
Loss of ocean predators has impact on climate change strategies

Continued unsustainable harvesting of large predatory fish, including the culling of sharks, can have far-reaching consequences for the way we tackle climate change.
How will offshore wind farms affect bird populations?
September 28, 2015 08:42 AM - University of Leeds
Offshore wind farms which are to be built in waters around the UK could pose a greater threat to protected populations of gannets than previously thought, research led by the University of Leeds says.
It was previously thought that gannets, which breed in the UK between April and September each year, generally flew well below the minimum height of 22 metres above sea level swept by the blades of offshore wind turbines.
Horse Owners Can Manage Flies with Wasps
September 25, 2015 09:49 AM - Entomological Society of America
Horses need help when it comes to insect pests like flies. But, unfortunately, horse owners are in the dark about how best to manage flies because research just hasn't been done, according to a new overview of equine fly management in the latest issue of the Journal of Integrated Pest Management, an open-access journal that is written for farmers, ranchers, and extension professionals.
