The Top 50 Scariest Television Episodes of All Time, Part 1. 46) What made the Night Stalker Zombie episode frightening was the climax: Kolchak has to climb into the zombie's resting place (a hearse in a junkyard) and, in order to immobilise it, Kolchak had to fill its mouth with salt and sew its mouth shut.

X-ray videos of people doing ordinary and extraordinary things. It significantly increases the chances of developing some kind of cancer.

How much it increases the chances depends on the total dose, but there is no guarantee if they will or will not develop cancer. Actually, these are not traditional X-rays as most people understand them to be. This is not a series of still images being taken, but rather video fluoroscopy, which uses a continuous lower mA X-rays over a longer period of time with an amplifying receiver to create a visual image. Notice the inverted image... on typical X-rays, bones show up on the white end of the gray scale, not black.

Depending on the length of time you're exposed, the actual absorbed dose is usually quite small. These are mostly used in upper GI examinations and Small Bowel Follow Throughs, imaging in the OR as guiding tools for localization of organs and instruments, and in angiography studies where they examine things like function of the arteries and veins feeding the heart. 8 Things We Simply Don't Understand About the Human Brain. Well done article, and a lot of fun to read.

8 Things We Simply Don't Understand About the Human Brain

Some points - we *do* know "how" memory is encoded; that is, Gary Lynch identified the micro changes in neurons that represent memory encoding. But this is like understanding how an AND gate works and trying to project that to a modern processor - in your head. "Free Will" as conceived by most people is the expression of a grand confusion about the state of affairs in the universe. Absolutely mindblowing video shot from the Space Shuttle during launch. Unless I'm misreading the speedo, the word "transonic" is used somewhat inaccurately.

If I'm not mistaken, the vehicle went transonic quite a bit before this point. The visible shockwaves only go on for a range of about 100mph, which seems too short for the passage from the initial transonic range to supersonic. What the producer seems to mean is that it is going supersonic (passing the sound barrier). Transonic means that there is both supersonic and subsonic flow somewhere on the vehicle. This starts quite a ways below the speed of sound, in most cases around Mach 0.75. The Mach Number calculation is not that easy since Mach Number is True Airspeed divided by the Local Speed of Sound. Corset-wearing superwomen from the Age of Steam. Mixed bag, honestly.

Some are just odd, others are dead on as far as in-character goes. Harley is cute, Emma is actually wearing more than usual and probably has an outfit exactly like that stashed for formal occasions. The Best New and Short Webcomics of 2012. SExpand I'm surprised more people haven't been talking about King of the Unknown.

I, personally, would've stuck a "probably" or a "possibly" in front of all my "NSFW"'s. That said, yeah, our culture's odd double-standards when it comes to being massive prudes are kinda odd, but I highly doubt the way to change anything is to not warn people who may be browsing io9 on a coffee break "Tits Ahoy! " (which should totally replace NSFW, if you ask me...), but to start applying the label more judiciously (and also, more specifically.

Another advantage of "Tits Ahoy! " Eight things you didn’t know you could do with human sperm. "Why would you need huge quantities of it?

" This question assumes a couple of things that are by no means conclusively proven: 1) I am highly skeptical that human sperm has any beneficial cosmetic effects. The Philosophical Roots of Science Fiction. This is a wonderful article, and I think it provides a lot of great insight into what science fiction's role really is.

The Philosophical Roots of Science Fiction

Tangentially, I think it also explains why so many older sci-fi fans are mourning the loss of Golden Age, Big Idea science fiction. As it's gotten older, science fiction has morphed from expansive, overt idea-exploring into more character-driven stories set in the microcosm of people's lives. We're less Asimov and more late-stage Heinlein. It's still exploring these ideas, just in a smaller, more intimate way.

It doesn't have the wonder and scale of the old stuff. I do, however, think that these core values of science fiction are still in play. This is perhaps the most beautiful footage of dolphins you've ever seen. Very.

I'd love to hear from someone more knowledgeable on the subject because that doesn't look right. The movement looks a little too perfect. Not enough variation. When one turns, it looks too smooth. Holy crap wtf News, Videos, Reviews and Gossip - io9. Not that young. I'm 24 and my great-great-great grandparents were born in 1860's; they were still children in the 1870's when the main photo of this article was taken.

It depends on the age at which each generation reproduces. Assuming a generation every 20 years, which is the standard base assumption, someone born in 1960 would be the correct generation to be the great-great-great-grandchild of someone who had his or her child in 1880. If you up it to 30 years per generation, which is a bit of a stretch but certainly not inconceivable, especially if we're not dealing strictly with first borns, for most of the period under discussion here, you hit three greats with someone born in 2000. So best answer to your question is anywhere between c. 12 and c. 52. Daily 10 News, Videos, Reviews and Gossip - io9.

Sir Lawrence Alma-Tadema, OM, RA (/ˈælmə ˈtædɪmə/;[1] 8 January 1836 – 25 June 1912) was a Dutch painter of special British denizenship. Born in Dronrijp, the Netherlands, and trained at the Royal Academy of Antwerp, Belgium, he settled in England in 1870 and spent the rest of his life there. A classical-subject painter, he became famous for his depictions of the luxury and decadence of the Roman Empire, with languorous figures set in fabulous marbled interiors or against a backdrop of dazzling blue Mediterranean Sea and sky.

Though admired during his lifetime for his draftsmanship and depictions of Classical antiquity, his work fell into disrepute after his death, and only since the 1960s has it been re-evaluated for its importance within nineteenth-century English art.

I seem to remember seeing somewhere that The Sneetches, who wore stars on their bellies, was actually originally conceived due to the Star of David that Jews were required to wear in Germany during Hitler's reign. Granted, the story of the Sneetches was more about "be happy with who you are, not with what someone else has" than ostracism via having to wear the Star of David.
