NASA’s real news: bacterium on Earth that lives off arsenic! | Bad Astronomy | Discover Magazine

NASA scientists announced today an incredible find: a form of microbe that apparently evolved the ability to use otherwise toxic arsenic in their biochemistry!

First off, just to be straight and to dispel the rumors: this is not aliens on Titan, or Mars, or anywhere else. This bizarre life form was found right here on good ol’ Earth. And don’t be disappointed: this is still pretty cool news.

This is the point where I should inject some sort of personal insight, or intelligent observation… but all I can really think of, right now, is: HOW FREAKIN’ COOL IS THIS?!?!!?!

My First Act of Free Will – LINK

There’s a certain frivolousness to all these eloquent arguments over free will. The fact is, we are deeply wired to believe in our freedom. We feel like willful creatures, blessed with elbow room and endowed with the capacity to pick our own breakfast cereal.

Free will, and whether or not it exists, is one of my favorite philosophical topics. This article over at Wired points highlights a take on the discussion I hadn’t thought of before. Very interesting read.

What do you think? Do we have free will, or is it an illusion we create to feel we have control over our lives?

BEHOLD! The Future, Today – LINK

That’s right, an ACTUAL flying car.

From the article: “It’s a two-seater. Front-wheel-drive. Gets about 30 mpg on the highway. But give it a third of a mile of straight asphalt in front of it, and it really flies.”

ARE YOU FREAKING KIDDING ME? Just yesterday, my 10 year old son asked me when we’d have flying cars. I guess now we know the answer.

What Is Time?

I’m trying to understand how time works. And that’s a huge question that has
lots of different aspects to it. A lot of them go back to Einstein and spacetime
and how we measure time using clocks. But the particular aspect of time that I’m
interested in is the arrow of time: the fact that the past is different from the
future. We remember the past but we don’t remember the future. There are
irreversible processes. There are things that happen, like you turn an egg into
an omelet, but you can’t turn an omelet into an egg.

Time is always a “wow this is fascinating; ouch my brain hurts” subject. This interview at Wired is a great read.

Check it out and tell me what you think. Is time liniar? Is it circular? Is it a myth?
