I Know You're Lying to Me

Please listen carefully to these options, as our menu has recently changed

No it hasn’t.

I suspect this behavior shows up somewhere on the list of ways you can manipulate people, in this case, trying to get me to listen to all the options instead of choosing the first convenient (and wrong) one or hitting “0.” Yes! 50 Scientifically Proven Ways to Be Persuasive

(I haven’t read the whole list, but am confident that by mentioning and linking to it, someone will read it and confirm that the behavior is indeed there. And that there are ways to persuade people to do your research for you, too, like checking to see if an item is on a list)

Looking for Mr. DNAbar

The Electric Slide

The researchers used computer simulations and analytical calculations to show that a simplified model of a protein is attracted to DNA until it gets within a half-nanometer or so. At this short range, the protein is repelled, so it can slide freely until it finds its target sequence and binds more tightly. The results provide a more complete physical picture of this critical biological process.

I’ve looked at clouds from both sides now*

The cloud with no name: Meteorologists campaign to classify unique ‘Asperatus’ clouds seen across the world

Experts at the Royal Meteorological Society are now attempting to make it official by naming it ‘Asperatus’ after the Latin word for ‘rough’.

If they are successful, it would be the first variety of cloud formation to be given a new label in over half a century

Also being pushed by the Charades Society to fill the empty “sounds like asparagus” clue niche.

Class, Pay Attention

Anyone want to try and guess why blowing on frikkin’ molten Aluminum (or slapping it with a glove) didn’t put the fire out? Bueller?

Healthy Graphing Technique

An interesting graph of life expectancy vs per-capita income, for a bunch of different countries around the world. What is so trés cool is that you can animate it to run it from 1800 to the present. France does a meteoric rise very early on with no change in income, war participants take hits in life expectancy, and basically the whole world does the Time Warp (it’s just a jump to the left) in 1929.

The Search for the Dragon(fly) Warrior

One of the questions I was asked in my most recent adoption was what I would do if I were not a physicist. I’m pretty sure I would do something in science, and I have an interest in evolution and paleontology. The stumbling block to going in that direction was the squishy part of biology — when I was in school, I was pretty sure animal dissection would start by making me weak-in-the-knees, followed by me throwing up, and I had no desire to test that prediction. Consequently, I haven’t studied a whole lot of biology, including entomology.

But dragonflies are pretty fascinating. They don’t fall under the “bugs to be avoided” category — not gross house-invaders, nor do they want to sting me. I had no idea that they flap their sets of wings out of phase, though it makes sense (if it were in phase, why not just have a bigger wing?) But I have some shots where it looks like maybe the two sets are at slight different frequencies, so the phase changes. I also didn’t realize how much they glide when they fly. And the flapping is low enough in frequency that it shows up well on a high-speed camera — a much lower pitch than many other insects.

It’s also really hard to pan a camera to follow them. I think I saw six distinct species; these were the biggest and flew high, while a few others tended to hug the ground, and yet others I only saw in the woods.

They Look Like Ants From Up Here

You get three ants together, they can’t do dick. You get 300 million of them, they can build a cathedral.

Look at what 6 – 7 billion people can do.

Time-Lapse Videos of Massive Change on Earth

Over the past decade, the number of people on Earth shot up by more than 13 percent, to nearly 6.8 billion people. To make room for all the hungry, breeding, CO2-emitting bodies on our small planet, we’ve ravaged Earth’s surface with staggering feats of deforestation, irrigation and urbanization — and NASA satellites have captured it all. Here are a few videos, compiled from images posted on NASA’s Earth Observatory, of some of the most impressive conquests of man over environment.
