Arctic River Ice Deposits Rapidly Disappearing

Climate change is causing thick ice deposits that form along Arctic rivers to melt nearly a month earlier than they did 15 years ago, a new study finds.

Air Pollution May Directly Cause Those Year-Round Runny Noses, According to a Mouse Study

Although human population studies have linked air pollution to chronic inflammation of nasal and sinus tissues, direct biological and molecular evidence for cause and effect has been scant. Now, Johns Hopkins researchers report that experiments in mice continually exposed to dirty air have revealed that direct biological effect.

Researchers have long known that smog, ash and other particulates from industrial smokestacks and other sources that pollute air quality exacerbate and raise rates of asthma symptoms, but had little evidence of similar damage from those pollutants to the upper respiratory system.

Cracking the code of a long-distance swimmer

Born in the Sargasso Sea, that Atlantic Ocean gyre east of Bermuda, baby European eels will travel 4,000 miles to the freshwater rivers of Europe. Now scientists might have answered a century-old question of how these young eels accomplish such vast oceanic migrations.

UBC researcher sees future for flax and hemp as particleboard alternative

Wood scientist Solace Sam-Brew envisions a future where Canadian homes are furnished with products made from flax and hemp.

“Both flax and hemp are widely available in Canada, especially in the West,” said Sam-Brew, a recent PhD graduate from the University of British Columbia’s faculty of forestry. “It’s worth considering their viability as alternative raw materials to wood for particleboard production.”

Birds sing shorter songs in response to traffic noise

Birds sing differently in response to traffic noise, which potentially affects their ability to attract mates and defend their territory, according to research published in Bioacoustics. The study found that a species of North American flycatcher sings shorter songs at a lower range of frequencies in response to traffic noise levels. The researchers suggest traffic noise reduction, for example through road closures, is a viable option for mitigating this effect.

Lyme Disease Imposes Large Cost On the Northeast United States

As people across the northeastern U.S. begin venturing back into the outdoors with the arrival of spring, they will make 1 billion fewer trips than they otherwise would have if Lyme disease didn’t exist, a new Yale study concludes.

New Battery Coating Could Improve Smart Phones and Electric Vehicles

High performing lithium-ion batteries are a key component of laptops, smart phones, and electric vehicles. Currently, the anodes, or negative charged side of lithium ion batteries, are generally made with graphite or other carbon-based materials.

Cover crops may be used to mitigate and adapt to climate change

Cover crops long have been touted for their ability to reduce erosion, fix atmospheric nitrogen, reduce nitrogen leaching and improve soil health, but they also may play an important role in mitigating the effects of climate change on agriculture, according to a Penn State researcher.

Eat, Prey, Move

It’s a fish-eat-fish world out in the ocean, and prey species usually fear the predators that would make them into a tasty snack.

New era of western wildfire demands new ways of protecting people, ecosystems

Just four weeks ago, fire crews battled the Sunshine fire in the foothills west of Boulder. Low humidity, record-high temperatures and 40 mile-per-hour gusts of wind helped fan flames that forced over 1,000 people to evacuate their homes. Firefighters quickly contained the wildfire, with no injuries or damage reported. But the reality of a blaze this serious in March raises concerns about how we deal with wildfire in the western United States.
