Editor's Picks: Iron Man, ZombieSat, Fat Dinos and More

If you weren't able to read every story Discovery News published this week (we forgive you), not to worry. Discovery News has got you covered.

Here are the top five stories that we've selected as this week's must-reads:

5. Grown Men Swap Bodies With Virtual Girl

Have you ever felt like a virtual girl trapped in a grown man's body?

Researchers have created a virtual environment that simulates what it's like to be in someone else's skin, even if that person is a different gender -- or resolution.

"When subjects looked down they saw a different body, suggesting that this was a powerful cue for the brain to generate the illusion that the virtual body was their own," said Mel Slater, a cognitive scientist at the University of Barcelona.

While it is very unlikely that this kind of experience is going to catch in the gaming community (think I'll just wait for "Red Dead Redemption" instead), this study could prove invaluable to future experiments involving body-consciousness and self awareness.

4. Most Fat Dinos Didn't Chew

This may sound like a cheesy, Paleolithic punchline at the expense of overweight dinosaurs. But according to research in the journal Biological Reviews, it's true.

At the same time, this finding may be one of those almost obvious "Eureka!" moments. Large animals need more food to survive, so they likely spend more time eating. If they're going to spend so much of their time taking in calories, why bother chewing? It's a waste of energy and a waste of time -- time that could be spent eating.

Added bonus: Less time chewing means less time in the dentist's chair. For animals with such small brains, dinosaurs really had a lot figured out.

3. 'King of Herrings' Found Off Sweden's Coast

Everyone knows you can't have an honest smörgåsbord without herring (OK, nobody knows that, but work with me here). So you can imagine how excited Sweden was when the "King of Herrings" -- an 11-foot-long fish not seen since 1879 -- washed ashore.

This rarely seen beast is the world's longest bone fish, and many believe it's at the origin of the sea serpent myth or other mythological sea creatures such as the Loch Ness Monster.

Although the fish was found dead, it will be preserved and likely displayed at the the House of the Sea museum in Lysekil, Sweden. So be sure to pre-order your tickets now if you don't want to wait behind the leagues of fans already lining up to see this fish!

2. Wake-Up Call: 'Zombiesat' Could Interrupt 'Lost' Finale

In April, a satellite called Galaxy 15 went rogue after it got fried by a solar storm, knocking out its ability to communicate with controllers.

With no human operators able to give it any commands, the satellite -- dubbed "zombiesat" -- has been left to its own devices.

Unfortunately, zombiesat may soon pass in front of another satellite, blocking its signal to Earth, potentially disrupting television service in the United States right around the time of the "Lost" series finale.

Granted, I've never seen the series, but I can imagine this news may be disheartening to fans. (From what I understand, "Lost" is a shot-for-shot remake of the "Swiss Family Robinson." Anybody care to dispute that? Comment below.)

1. Is Iron Man 2's Home-Made Particle Accelerator Possible?

If there's one thing I learned from watching Iron Man 2 last weekend, it's that money can make you a superhero. (Hat tip to Batman for driving home the same point.)

If there are two things I learned from watching Iron Man 2 last weekend -- with a little help from Jennifer Ouellette, of course -- it's that I can build my own particle accelerator at home.

It's just like baking a cake. All you need is a beam tube with a large vacuum, charged particles, magnets to bend the beam, and radio frequency oscillators, or RF cavities, to accelerate the particles. It just doesn't get any easier than that.

Those were the top stories that we selected. But what did YOU think?

Here are the most popular stories we published this week:

5. Ancient Egyptian 'Nilometer' Helped Measure River's Height

Stylish and functional, the structure was among several new discoveries at the so-called Avenue of Sphinxes. Rossella Lorenzi has the story.

4. Baby Star Blows a Bubble, Force-Feeding a Stellar 'Goliath'

Baby humans blow bubbles in milk. Baby stars blow bubbles in space. Ian O'Neill can fill you in on the rest.

3. Why We Sigh (It's a Human Reset Button)

Sighing is an essential part of an inherently chaotic system: breathing. Larry O'Hanlon has the story.

2. Our Weird Universe Not As 'Constant' As We Thought

Who would have thought "constants" could be so variable? Nicole Gugliucci, that's who.

1. No, Seriously, Why is the Sky Blue?

Michael Reilly knows the answer. Do you?
