Cutthroat trout cross-breeds to survive
Scientific American
Any Montana angler worth a double-haul cast knows that the iconic state fish, the westslope cutthroat trout, has been crowded out by the non-native rainbow trout, first introduced to these rivers by well-meaning sportsmen in the 1880s. Now those invaders are taking over the cutthroat's gene pool, too. A new study tracks just how rapidly cross-breeding between the two species has accelerated in the past 30 years. It's invasive hybridization driven by climate change, and it could spell extinction for the ruby-throated native fish of the Big Sky state.

Toxic effects of ocean plastic far greater than previously thought
Epoch Times
When dead seabirds washed up in their thousands along the eastern and southern seaboards of Australia last year, biologist Dr Jennifer Lavers became worried, very worried. A research fellow at the Institute for Marine & Antarctic Studies in Hobart, Dr Lavers had been studying flesh-footed shearwaters, also known as mutton birds, for nearly a decade. She knew that mass deaths, known as "wrecks," were not uncommon for the migratory shearwaters, which travel huge distances from the Bering Sea to Australia every year.

White hot insects: Climate change leading to lighter colors
Discover
Most of the discussion on climate change focuses on startling images of potential loss: the city of Miami underwater due to rising sea level or the lone polar bear on an ever-shrinking iceberg. But some of the greatest impacts of our continued inability to curb our carbon appetite are surprisingly small — little changes that may ultimately have big implications. It's the butterfly effect — except, in this case, it literally is about butterflies.

Experts: Impact of pesticide residue hard to track
Harvard Gazette
Pesticides have been linked to Parkinson’s disease, declines in cognitive performance, developmental disorders, and attention-deficit/hyperactivity disorder in children. Their application has also been tied to environmental issues, such as the collapse of honeybee colonies and the development of resistant pests and weeds. But we know surprisingly little about population-wide health effects of the low doses that are in the foods we eat every day, panelists at the Harvard School of Public Health said.

Vancouver for craft beer nuts
The Boston Globe
So many independent producers have recently opened in Western Canada's largest metropolis that it's easy to claim Vancouver as the country’s current craft beer capital. "Since many also have inviting little tasting lounges, I've plotted a course around four of the newest hot spots," writes John Lee.

The red hot renewable that could incite a green power revolution
Think Progress
Earlier this year, researchers in Iceland found a new way to transform the heat generated by volcanic magma into electricity. The advancement could be especially valuable in Iceland, a country that has capitalized on its unique geology to derive a quarter of its electricity production and around 90 percent of household heating from geothermal energy.

Silver too small to see, but everywhere you look
The New York Times
Several years ago, a mosquito bite on Elizabeth Loboa's right leg became infected, turning into an oozing sore that refused to heal. Her doctor prescribed a stiff course of antibiotics. But Dr. Loboa decided to try another remedy. An associate professor of biomedical engineering at North Carolina State University, she had been experimenting with a new kind of bandage, a scaffold of microscopic fibers that could be inserted into a wound to encourage tissue growth. The fibers were coated with silver to fend off infection.

Brought on by climate change, toxic blue-green algae are expected to return to Ohio's Lake Erie this summer, according to recent research. On the heels of the recently released 3rd US National Climate Assessment, nearly 200 scientists spoke at a conference at The Ohio State University to discuss how climate change is projected to affect the state of Ohio.

Ancient soils are 'reservoirs' of carbon and could contribute to climate change
International Business Times
There is far more carbon stored in the Earth’s soil than previously thought, a new study has shown, and scientists fear disturbing it could unleash vast amounts of it into the atmosphere. According to new research, published in the journal Nature Geoscience, ancient soil that was buried thousands of years ago has been found to be rich in organic carbon. The soil is up to six-and-a-half meters, or 21 feet, below the present-day surface and could be exposed through erosion, agriculture, mining, deforestation and other human activities.
