WaPo: Stop worrying about honey bees

WaPo: Record number of honey bees

WaPo: Record number of honey bees

After almost two decades of relentless colony collapse coverage and years of grieving suspiciously clean windshields, we were stunned to run the numbers on the new Census of Agriculture (otherwise known as that wonderful time every five years where the government counts all the llamas): America’s honeybee population has rocketed to an all-time high.

When I started keeping bees 15 years ago, the corporate media was covering the impending environmental catastrophe of honey bee extinction.  To populate a bee colony, a beekeeper can purchase a 3 lb package of bees.  That’s around 30,000 live bees with a queen.  When I started, a package cost about $120.  The price has gone up about $5 per year, but never drastically from year to year.  That convinced me that honey bee extinction wasn’t likely.

To summarize, this census only counts beekeepers with more than five hives.  It would also only count beekeepers who register their hives.  I never registered mine.

The challenges to bee colonies still exist, but various treatments mitigate the problem.

Changes in Texas tax law made it advantages to keep bees and register hives, so many more people did.

Honey bees are not indigenous to the US.  Many other insects pollinate plants.

My beekeeper instructor told the class that wild honeybees no longer exist.  The article suggests that the increase in domesticated bees will threaten wild honeybees.

Like most impending environmental catastrophes, people involved are managing the issues and the rest of us don’t have to worry about it.

Guardian: Researchers prove that dogs are smart.

Dogs understand what certain words stand for, according to researchers who monitored the brain activity of willing pooches while they were shown balls, slippers, leashes and other highlights of the domestic canine world.

The finding suggests that the dog brain can reach beyond commands such as “sit” and “fetch”, and the frenzy-inducing “walkies”, to grasp the essence of nouns, or at least those that refer to items the animals care about.

It’s good to see that researchers have finally caught up with what I figured out after a year with Sparky.  After a year of practice, Sparky does not differentiate between Bunny and Mr. Moose.  To him, “Moose” means a stuffed animal.  “Crate” means run to his crate.  “Bed” means run somewhere, but not necessarily to his cushion in my bedroom.  We’ve practiced this almost every day, and that’s as far as he will ever get because it seems good enough to him. 

One time, I said, “car ride”, and Sparky knew to run down to the garage and rush to the passenger side of my truck.  He might have learned “car ride” prior to coming to me, but to know exactly where to go was impressive.  Sparky really likes car rides.

During the tests, researchers monitored the dogs’ brain activity through non-invasive electroencephalography, or EEG. The traces revealed different patterns of activity when the objects matched or clashed with the words their owner said. The difference in the traces was more pronounced for words that owners believed their dogs knew best.

I can’t help thinking that dog researchers finally got time on an EEG machine.

While playing with Sparky, I found a related research topic.

When I tease Sparky with Mr. Moose, his eyes are locked on it.  If I hold Mr. Moose behind my back, his eyes remain locked on where Mr. Moose should be based on the position of my arm.  If I pull my arm out without Mr. Moose, Sparky is completely baffled and starts to look for Mr. Moose.

I don’t know what that means, but it seems like if he saw my arm holding Mr. Moose, my arm is an extension of Mr. Moose.  When my arm comes out without Moose, then that connection is broken.

A newly popular alternative to cigarettes is changing the way many Americans consume nicotine—and becoming a political flashpoint.
The product, a nicotine pouch, looks like a tiny tea bag and comes in flavors such as mint, coffee, berry and mango. It tucks discreetly into the cheek and doesn’t require the user to spit.

I have never smoked a cigarette in my life.  Pulling hot smoke into your lungs always seemed like a bad idea.  When I was young, I figured that lungs were moist, pink mucus membranes kind of like the inside of your mouth.  Hot smoke would dry them out and damage them.

Keep it in the distant family.

Sperm counts and fertility have been dropping for a hundred years.  This could become a problem.

Women having fewer children could be explained by societal changes that mostly converge to women having more life options and control over their fertility.  The drop in sperm count is not easy to explain, but everybody wants to attribute the decline to whatever agenda suits them. 

In my first quarter at The Ohio State University, I took Bio 100 because, at the time, I was majoring in natural resource management.  Everyone majoring in a non-STEM field took it.

The professor was an engaging lecturer, with some wit.  He was explaining dominant and recessive genes, and explained how inbreeding increases the chances of passing along harmful, recessive traits.  He ended with, “So if you want to have the healthiest kids, breed with someone of a different race.”  In 1979, this was a mildly subversive thing to say.
