3:41 PM | Footage of the 8th International Congress in Genetics! (Stockholm, 1948)
While searching for information regarding Åke Gustafsson, a plant breeder who practiced mutagenesis (and cited by Stebbins as providing experimental data for mutation studies), I stumbled upon an amazing video: footage from the 8th International Congress in Genetics held in Stockholm in 1948! Bengt Bengtsson and Anna Tunlid of Lund University digitized and annotated the video (the […]

10:09 PM | Sunday Chess Problem
My renewed interest in chess has not just extended to tournament play. I am composing chess problems again as well. Here’s one I came up with recently, and which will eventually be published in The Problemist magazine.

10:04 PM | How to kill an iZombie
Sometime back TPP commented on iPhone zombies, but a similar affliction can also occur due to ear buds and whatever they are delivering from an iPod, so the result is an iZombie. Like all zombies, you have to know the right way to kill them, but based on recent events that may not be too difficult. You turn an ordinary person, often a student around here, into an iZombie by giving them a smart phone and a set of ear buds either attached to the iphone or an ipod, either or both […]

7:40 PM | Robert Kennedy's Anti-Vaccine Craziness
Robert Kennedy is obsessed with the notion that vaccines cause autism. He’s particularly obsessed with the discredited idea that thimerosal, a preservative used in some vaccines, causes autism. Now Kennedy is about to publish a new book on this topic, and he’s promoting it both in the press and, as described in today’s Washington Post, in the halls of Congress. He’s recently had personal meetings with U.S. Senators Barbara Mikulski and Bernie Sanders to try to convince […]

Over on Facebook, Nancy Pearcey responded to a post about young people and deconversion from churches with a modest proposal: let them read apologetics. Age at which people leave the church — Tell me again why youth groups focus on games and goodies instead of majoring on apologetics? One study found that the age at […]

10:45 PM | Barbarians and their enablers
You give a kid a BB gun, and sooner or later he'll shoot it at some windows. It's a given of human nature. You give rebels, terrorists, or even some other type of militia under limited central control some big boom-booms, and sooner or later they'll shoot at something they shouldn't have.  And of course giving an implement of destruction to anybody who is more likely to shoot than to think makes you partly responsible for the outcome. This means you really have to think […]

4:42 PM | Fraud, Deception And Lies: How Discovery’s Shark Week Became The Greatest Show On Earth
In 1842, the infamous showman P.T. Barnum unveiled a truly bizarre creature. In his autobiography, Barnum described it as “an ugly, dried-up, black-looking, and diminutive specimen… its arms thrown up, giving it the appearance of having died in great agony.” The Feejee mermaid, as the mummified remains were called, possessed the torso of a monkey with […]The post Fraud, Deception And Lies: How Discovery’s Shark Week Became The Greatest Show On Earth appeared […]

2:32 PM | Passport required to reproduce: Local adaptation persists despite frequent dispersal
[ This post is by Daniel Peterson; I am just putting it up.  –B. ]Alaska contains roughly half of the wilderness in the United States. That’s over 230,000 square kilometers of pristine habitat – a place where ecosystem processes disrupted almost everywhere else can be observed in a natural state. Of course, that also means a large proportion of the state isn’t accessible by road, a fact I could barely comprehend as a brand-new grad student stepping off a plane from […]

The anti-evolutionists just never get tired of the second law thermodynamics! The latest bit of silliness comes from Barry Arrington, writing at Uncommon Descent. Here’s the whole post: I hope our materialist friends will help us with this one. As I understand their argument, entropy is not an obstacle to blind watchmaker evolution, because entropy…

They are part of a series we’ve done on the silicified fauna of a block of limestone we dissolved in the lab many years ago. The calcitic shells […]

7:55 PM | Stop teaching calculus in high school
Math education needs a reboot. Kids today are growing up into a world awash in data, and they need new skills to make sense of it all. The list of high school math courses in the U.S. hasn’t changed for decades. My daughters are taking the same courses I took long ago: algebra, geometry, trigonometry, and calculus. These are all fine subjects, but they don’t serve the needs of the 21st century. What math courses do young people really need? Two subjects are head-smackingly […]
