This video is a re-enactment of what happened at Hiroshima after the nuclear bomb detonated there: This was a tiny bomb by today’s standards, and of the simplest design (for more info on the bomb’s design and yield, see How Nuclear Bombs Work). Yet the effects on the city were gigantic. Nearly everything within a [...]
If sharks die when they stop moving, can sharks sleep?
by Marshall Brain | February 27, 2009
You asked: If sharks die when they stop moving, can sharks sleep? — Allia, Ponce, Puerto Rico Marshall answered: See this page for the answer: Will a shark drown if it stops moving?
You asked: Are there any sharks, other than bull sharks, that can survive in fresh water? — Jonnie, Grover Beach, Calif. Marshall answered: The bull shark actually handles both fresh and salt water. But there are also several shark species caller river sharks that live in fresh water. Like the freshwater dolphin that recently went [...]
What exactly happened to the dinosaurs that them wiped them off the earth?
by Marshall Brain | February 27, 2009
You asked: What exactly happened to the dinosaurs that them wiped them off the Earth? — Luke, Edson, Canada Marshall answered: There are many theories, running from an asteoid impact or a giant volcanic eruption to more gradual climate change. To explore the possibilities, see Dinosaur Extinction.
You asked: Why do some birds stand on one leg sleeping? — Tuyet, Ha Noi, Viet Nam Marshall answered: The truth is that no one really knows for sure. Could it have to do with the way birds sleep? Unlike humans, some birds are known to let only half of the brain sleep at a [...]
Oddly, I was thinking just this morning that despite the popularity of some older arcade games, that no one would put out something as simple as Space Invaders again. Turns out, I was wrong.
For the uninitiated, Space Invaders is a simple game. There’s an invading horde of creatures slowly making your way to your planet. Your job is to shoot them down with your … cannon? Rocket ship that doesn’t leave the ground? Gun thingy? … that slides back and forth horizontally and can hide behind shields, at least, until the invaders reach that level, when they disappear. That doesn’t sound fair, does it? Nor is it fair that with each alien you take out, his or her buddies speed up a notch, until the last one’s chugging downscreen at an alarming and very hard-to-hit rate.
Among the many, many things your snazzy iPhone can accomplish, add one more: It can sniff out ghosts. Or pretend to. A company called Moderati Inc. released a simulated paranormal state EMF meter that you can download free on iTunes. It turns out the app is more of a promo for the A&E show “Paranormal State” than anything that will help you detect beings suspended between our world and the hereafter. It did get me curious about EMF meters and if I could buy one if were so inclined. Yeah, yeah, I’m the science editor, but I will admit to being fascinated by ghosts. Berate me if you will.
An EMF meter or reader measures the electromagnetic fields in your immediate surroundings, be they haunted house or humdrum household. Ghosts supposedly have strong electromagnetic fields that will register on your handheld meter and confirm or deny your paranormal suspicions.
During a ceremony held yesterday at the Indianapolis Motor Speedway Hall of Fame Museum in Indianapolis, Indiana, the 2010 Chevrolet Camaro was announced as the Pace Car for the 93rd running of the Indianapolis 500.
According to a statement made by the Indianapolis Motor Speedway, the Camaro Pace Car will be running completely stock out in front of the 33 competitors on race day:
“Powered by the 6.2-liter LS3 all-aluminum Chevy V-8, the all-new 2010 Camaro produces 426 horsepower at 5,900 rpm and 420 lb-ft of torque at 4,600 rpm. It features a Tremec six-speed manual transmission and 3.45 axle ratio. No drivetrain or suspension modifications are required to prepare the Camaro for its Pace Car duties. The only modifications to the vehicle include a fully integrated strobe system, including a GM-designed custom light bar utilizing Whelen 500 series linear strobes.”
Podcast Goodness: Can people really die of fright?
by Charles W. Bryant | February 27, 2009
This week on the Stuff You Should Know podcast we discussed a couple of interesting topics. Yesterday’s show was about how to stop junk mail, which is something everyone definitely should know. Tuesday’s show was a gem called “Can people really die of fright?” It was based on a stellar article by staff writer Molly Edmonds. Josh and I delved a bit into the science of fear and the potential medical issues that could arise if you were really scared — aka the “Baskerville Effect.”
We also looked at some interesting studies. One took a look at the death rate of people in China and Japan on the fourth day of the month, four being an unlucky number in much of Asia. They found that there was a 13 percent increase in heart failure on the fourth of each month compared to a Caucasian control group. So there’s something to be said for chilling out on the fourth if you’re Chinese or Japanese.
Is it possible for someone to hate the iPhone? What about a whole nation of people? It is possible, because it appears that the entire nation of Japan could care less about the iPhone: Why the Japanese Hate the iPhone Why do they hate it? Let us count the ways: 1) The high cost per [...]
