If it isn't polar bears in the North Pole, it's penguins in the South. Hundreds of dead baby penguins have washed up on the beaches of Rio de Janeiro over the past two months. Story in the full article.

Human beings have a bad habit of making the place they inhabit quite uninhabitable. (I like the word "habit" for some reason.) The sad thing is, human beings as a race would probably be the last to suffer its own mistakes - it's the rest of the world that would suffer first, and it looks like the polar bears of the Arctic are the next casualties. In this edition of the Science Weekend Warrior, we take a look at what it's like to be on top of the food chain.

So the North Pole is melting and polar bears are on the verge of extinction. Solution? Ship 'em off to the other pole, to Antarctica. Lame. Story in the full article.

There used to be water on Mars, we know as much. Just last week, NASA's Phoenix Spacecraft discovered of ice underground. This week, a group of UC Berkeley researchers posited that Mars' atmosphere can be likened to deserts we have here on Earth, and that it even rained in the red planet. How was this possible? Learn more after the jump.

Couch potatoes, it's again time to bust out the popcorn as new releases on Blu-ray are about to hit the shelves. This week, we've got a slew of titles from Sony Pictures (Walk Hard, The Water Horse, The 6th Day), a shark documentary from National Geographic, an interactive feature called Space Ace, and an anime OVA entitled Yukikaze. Check out the list in the full article.

If a 160-square-mile ice shelf collapsing isn't a sure sign of global warming, then we sure as heck don't know anymore what is. Last month, a huge chunk of the Wilkins ice shelf in Antarctica broke away from its main body, and the remaining bulk of it is about to give way any time soon. Scientists are not as disturbed, though. Read on to the full article to know why.

Australia's Aurora Australis, a marine science research vessel, recent came back from its trip from Antarctica. Dr. Martin Riddle, leader of the voyage, said that their expedition was able to uncover the rich and complex marine life in the previously unknown environment. Find out what they discovered in the full article.

Underwater volcanic eruptions are fairly common, but under-ice eruptions? Not so much. Scientists have discovered evidence of a volcano erupting under the Antarctic ice sheet 2000 years ago. Details in the full article.

The Southern Ocean Whale Sanctuary is a vast stretch of ocean near Antarctica, 50 million square kilometers in size and ordained as a whaling-free zone by the International Whaling Commission. Unfortunately, the strict zero-whaling rule isn't honored apparently as the Greenpeace ship called the Esperanza spotted a Japanese whaling fleet within the sanctuary. What followed was a game of cat and mouse, and Greenpeace took the field...for now.

It's been a few days since Halloween, so we'd rather honor the most memorable deaths that made gamers shriek, throw tantrums, and cry. Of course, along the line are deaths so dramantic, shocking, or simply sad that they're difficult to forget. In other words, a list of characters who died in ways that scarred our minds, or those we felt so attached to that seeing them perish became emotional. If it's not obvious enough, we'll have to warn you about major spoilers that await.
