Snow Coyotes and Spirit Bears

Posted on by Matt Kristoffersen

Twenty eight years ago, the first coyotes arrived in Newfoundland. They had come a long way.

Up until the 1800s, coyotes lived mostly in the southwestern United States, and in low numbers in the Midwest. To the east and north, wolves shut them out of their forests. But when farmers and trappers exterminated wolves in much of North America, the coyotes began to expand their range. By the 1970s, they had reached the far corners of New England. In the winter of 1985, there were reports in Newfoundland of wolf-like animals traveling across the ice to the Port au Port Peninsula. In 1987, a car hit one of the animals, and it was confirmed to be a coyote pup. The coyotes had come about as far east as they possibly could.

A Trilobite For Your Nightmare (Science Ink Sunday)

Posted on by Matt Kristoffersen

Meredith Palmer writes, “I am currently working on Guam studying the invasive Brown Tree Snake. I graduated with my B.A. in Zoology in 2011 and have spent the last year or so in Africa studying large mammals, in the Caribbean examining guppy evolution, and in Canada digging up dinosaurs. And now I find myself in the Pacific! The plan, however, is to attend graduate school next fall. Although I majored in zoology, I always had an interested in paleontology born out of cold, rainy childhood summers spent cracking shale in New England with my geologist parents. Dicranurus is one of my favorite trilobite species, and the design is modeled after scientific plates in the publications of Barrande, a Boehmian paleontologist from the 1800s.”

Barrande’s beautiful illustrations are posted on the Smithsonian’s web site. For more on the glorious vanished trilobites, visit A Guide to the Order of the Trilobites.

Viruses That Make Zombies and Vaccines

d of flu vaccine. Nestled in the articles was an odd fact: unlike traditional flu vaccines, the new kind, called Flublok, is produced by the cells of insects.

This is the kind of detail that you might skim over without giving it a thought. If you did pause to ponder, you might be puzzled: how could insects possibly make a vaccine against viruses that infect humans? The answer may surprise you. To make vaccines, scientists are tapping into a battle between viruses and insects that’s raging in forests and fields and backyards all around us. It’s an important lesson in how to find new ideas in biotechnology: first, leave biologists free to explore the weirdest corners of nature they can find.

Black Carbon and Warming: It’s Worse than We Thought

It rises from the chimneys of mansions and from simple hut stoves. It rises from forest fires and the tail pipes of diesel-fueled trucks rolling down the highway, and from brick kilns and ocean liners and gas flares. Every day, from every occupied continent, a curtain of soot rises into the sky.

What soot does once it reaches the atmosphere has long been a hard question to answer. It’s not that scientists don’t know anything about the physics and chemistry of atmospheric soot. Just the opposite: it does so many things that it’s hard to know what they add up to.
