Humans take pride in their unique, perhaps exalted, place among creatures. We’re the only animal that can point to triumphs like space travel, nerve gas, for-profit prisons, and plastic-filled oceans. Until recent times, we also thought we stood alone in our taste for addling our brains with drugs. Alas, we can no longer claim that distinction: Dolphins, dogs, wallabies, waxwings, and loads of other species like to get loaded. [Read more…] about Wildlife Gone Wild: Animal Intoxication
Late-Season Yellowjacket Anarchy
I’m not one to shed a tear when authoritarian rulers die, but once they’re gone, picnics become a lot more dangerous. As summer wanes, the original queen in every yellowjacket wasp colony dies – having a few thousand babies in the course of one season is enough to tire any Queen Mum to death.

Tree Sign Language: Early Fall Color Spells Trouble
Each fall deciduous trees, ice-cream stands, and marinas close for the same reason: as daylight dwindles and cold creeps in, they become less profitable. When income dips down to equal the cost of doing business, a wise proprietor will turn off the lights and lock the doors until spring.
Some enterprising holdouts stay solvent longer than others who are in the same business. Perhaps they have less competition or a better location. Conversely, a few businesses close their shops at the first whiff of autumn. Those are the ones that just barely scrape by at the height of summer.

Goldenrod and The Golden Rule
Unless you have bees up your nose on a regular basis, don’t blame late-season allergies on goldenrod. However, if you do find bees in your schnozz, seek medical (and perhaps entomological) help immediately. While most plants respond to the shrinking hours of daylight in the late summer by starting to wind down their business for the season, goldenrod is a “short-day” plant, the type that is stimulated to bloom by dwindling light.

Fly Research Yields Possible Trauma Treatment
Though the phrase “garbage in, garbage out” is a decades-old caution for techies to be mindful when writing code or entering data, I thought my mom invented it. It was her stock retort when we kids asked why two hours of Saturday cartoons was plenty: “Garbage in, garbage out. Fill your heads with foolishness, and you’ll act that way.” I guess she was afraid we’d start chasing roadrunners across the desert, which typically leads to sprinting off cliffs and being struck by falling anvils.
It turns out she had a point. Numerous studies confirm that exposure to graphic TV violence raises a child’s level of aggression and anxiety in the short term, and is a sound predicter of hostile behavior as an adult. [Read more…] about Fly Research Yields Possible Trauma Treatment
White Pines: Physically & Culturally Colossal
The eastern white pine (Pinus strobus) isn’t really a crop-bearing tree, but it has borne priceless fruit for American democracy. Physically as well as culturally massive, there are many accounts from the early 1800s of white pines over 200 feet tall being harvested. One credible report pegs a white pine at 247 feet, and unverified accounts have claimed that 300-foot-tall leviathans were cut back then.

Oaks Will Be Oakay
If you’ve wondered what awful new malady has struck our oak trees this spring, resulting in shriveled, deformed and dead leaves, the answer is chilling. Literally; as in cold. A hard freeze on the night of May 17-18 happened at just the right – or wrong – time, catching oak foliage at a critically tender stage. Since trees can’t change their locations (to my knowledge, at least), I guess you could say that oaks were in the right place at the wrong time. [Read more…] about Oaks Will Be Oakay
Tick Season is Here
Black flies can put a damper on summer fun, but a tick bite can change your life forever. Deer ticks are known to transmit Lyme disease, which is caused by any of three species of spirochete bacteria in the genus Borrelia. When a deer tick latches onto us for longer than 24 hours, it barfs a load of these fast-moving, corkscrew-shaped microbes into our bloodstream. The spirochetes, which have a particular craving for hearts, brains, and joints, begin to drill through our tissues in search of a nice place to settle down and reproduce.

Coltsfoot: Eye Candy, Cough Syrup, and Early Flowers
After many months (five-plus where I live) of winter whiteness, it’s a relief to watch the snow melt at last. We’re always grateful, even though the loss of snow cover gives way to a mostly brown world: brown grass, sand everywhere – even brown pine needles along the roads.
Not to mention the leaves, trash, or dog poop that was mercifully hidden under the snow. Those few sepia-toned weeks after the white stuff disappears and before trees and grass wake up can be visually bleak. [Read more…] about Coltsfoot: Eye Candy, Cough Syrup, and Early Flowers
Girdling Roots Kill Trees
“My girdle is killing me” was an obnoxious slogan from a TV ad that ran in the late 1960s and early 1970s in the US. The widely-mocked catchphrase was meant to inspire women to rush out and buy a certain brand of non-murderous undergarment. I doubt the ad’s plaintive tone helped boost sales, but hey – I’m no marketing expert.
And yet, underclothes can be dangerous. [Read more…] about Girdling Roots Kill Trees
