The Periodic Table of Rejected Elements

Poor Fahrvergnügen. I totally agree with the rejection of Celinedion, though.

How? Very carefully.

Aquatic mammals have a unique challenge when it comes to sleeping. They have a voluntary respiratory system (as opposed to our mostly involuntary one), meaning that they have to come to the surface, actively open the flap of skin covering their blowhole, and then take a breath. But they also need to sleep. How do they do it?

Observations of dolphins have shown biologists that they sleep either floating still at the surface (called “logging”, a deeper sleep) or by swimming very slowly, usually with another dolphin around. You might be wondering “But Joe, how can they swim if they are asleep?”, to which I say “Nice to see you’re paying attention …”

Dolphin sleep is not like human sleep. I couldn’t find any examples of them reaching anything like our deep REM sleep. Instead they seem to do something that resembles napping. They are able to “shut off” one half of their brain and the opposing eye, with the other half staying awake to watch for danger and to control the voluntary breathing. Infant dolphins get pushed along in their mothers’ slipstream while resting, since their lack of buoyancy means that they have to swim or sink. And all whales have the ability to tolerate much more carbon dioxide in their blood than we can, allowing this sleep/breathe trade-off to work.

So while dolphins spend about as much time per day as we do in a sleep-like state, they space it out throughout the day, and can be more active at night when there’s lots of squiddy snacks to be had. Every animal needs rest, especially one with the brain energy demands of a dolphin. They’ve just evolved a very unique and useful way to get that rest.

How to Be Creative

Creativity is not a trait that we inherit in our genes or a blessing bestowed by the angels. It’s a skill. Anyone can learn to be creative and to get better at it. New research is shedding light on what allows people to develop world-changing products and to solve the toughest problems. A surprisingly concrete set of lessons has emerged about what creativity is and how to spark it in ourselves and our work.

The Man Working To Reverse Engineer Your Brain:

Seung’s new book, Connectome: How the Brain’s Wiring Makes Us Who We Are, explains how mapping out our neural connections in our brains might be the key to understanding the basis of things like personality, memory, perception and ideas, as well as illnesses that happen in the brain, like autism and schizophrenia.

Animals Smuggled On Airplanes

Each year, more than two million live animals travel on commercial aircraft in the United States.

This collection of endangered seahorses was part of an exhibition at the London Zoo of animals seized by Metropolitan Police from smugglers. According to a roundup of the illegal pet trade in 2006 from LiveScience, up to 21.6 million seahorses are captured and traded illegally each year, some of which belong to endangered species, for use in Chinese medicine.

These otters made it through airport security without issue because the TSA knew they were coming. But there are travelers who try to smuggle animals without permission through the air across state or international borders.

Google Street View Goes Under The Sea

Now that it’s conquered all seven continents, mapped the Amazon, some rivers in the United States, caves, the ruins of Pompeii and captured snapshots of naked women, Google Street View’s next expedition will turn its lens on the mysteries of the deep when it goes under the sea.

What happens when your teenage son is obsessed with nuclear research and wants to experiment in the backyard? How 17-year-old Taylor Wilson found support from his family and a group of scientist mentors:

Kenneth and Tiffany agreed to let Taylor assemble a “survey of everyday radioactive materials” for his school’s science fair. Kenneth borrowed a Geiger counter from a friend at Texarkana’s emergency-management agency. Over the next few weekends, he and Tiffany shuttled Taylor around to nearby antique stores, where he pointed the clicking detector at old radium-dial alarm clocks, thorium lantern mantles and uranium-glazed Fiesta plates. Taylor spent his allowance money on a radioactive dining set.

Drawn in by what he calls ‘the surprise properties’ of radioactive materials, he wanted to know more. How can a speck of metal the size of a grain of salt put out such tremendous amounts of energy? Why do certain rocks expose film? Why does one isotope decay away in a millionth of a second while another has a half-life of two million years?

Clean Coal: Not a Thing

squashed:

The coal companies are lying to you. Coal energy is not clean energy. It is the dirtiest form of energy generation we have. The coal companies are spending millions of dollars hoping you’ll forget this. A slick ad campaign doesn’t change the truth.
