Bears: The Future of Space Travel

Well, not so much the bears themselves–something tells me that letting a grizzly loose on a space station might not be particularly beneficial to the mission. Rather, the key here is bear hibernation, which scientists believe could be a key to enabling travel into deep space.

This assessment comes after a recent study conducted by the Alaska Department of Fish and Game, which found that hibernating black bears slow metabolic activity by 75 percent, despite only slight reductions in their body temperatures. Generally it’s understood that large changes in metabolism come with large changes in body temperature, a 50 percent drop in metabolism coming with a 50 degree Fahrenheit drop in temperature.
Scientist Øivind Tøien describes the measuring process thusly,
We measured the bears’ metabolism by continuously measuring the oxygen and carbon dioxide concentrations of the air entering and leaving the den. The transmitters inside each bear told us that the bear’s body temperature was not stable, but varied over the winter in slow cycles each lasting several days

Tøien believes that the discovery could make it possible to induce hibernation in people, thus making it possible to survive the long periods required for deep space travel.

Pluto: A Timeline

Tomorrow marks the 81st anniversary of the discovery of Pluto, that troubled little celestial body that has become the subject of a heated planetary status debate over the past decade or so. In honor of the little dwarf planet, and the recent “discovery” of a giant planet six times the size of Jupiter, which may or may not exist at the edge of our solar system, we’re taking a quick trip down memory lane.

Corning’s Glass-Filled Vision of the Future

Corning - Day of Glass

Corning, makers of fine glassware and ceramics that you probably already have in your kitchen, sees the future, and it has a lot of glass in it. A lot of touch-sensitive, multi-functional, all-encompassing glass that will cover virtually every device we carry with us and every object we interact with. 
The “A Day Made of Glass” video (video’s behind the jump) suggests a possible future where we all carry transparent glass-phones that look conspicuously like iPhones that interact seamlessly with everything in our homes, 3D televisions that literally jump out at you (without glasses, of course,) and cars with touch-panels that spring to life when you approach the vehicle. 
Admittedly none of this technology exists in the consumer market just yet, but none of it is so terribly far-fetched given current trends that it couldn’t be possible in the near future. The idea of interactive televisions that display traffic conditions and weather while you’re checking out the morning news is nothing new, and neither is the idea that a computer system in a store can identify you when you approach and suggest products that you like. If you’re thinking that part looks a lot like the movie Minority Report, you wouldn’t be too far off.
Still, while reality never really turns out like these concept videos (after all, brushing your teeth and checking your messages at the same time is all well and good until your mirror blue-screens on you) one thing is for sure: if Corning has its way, the future will need a lot of Windex.

Do Synchronized Goldfish Constitute Animal Abuse?

A Chinese television station is drawing fire for a broadcast of magician’s synchronized goldfish act. Animal rights groups have criticized Fu Yandong for the trick, which they believe involves magnets, harming the fish in the process. 

Yandong, for his part, denies that the trick actually harms the fish, though he hasn’t actually revealed how it’s done–he is a magician, after all. “If I used magnets, the fish would stick together,” Yandong told the press.”Some people say I use electricity or high technology. They can say what they want, but the fish are safe.”

British Ancestors Used Human Skulls as Bowls

Say what you will about the forward march of technology, we’ve made some undeniably positive advances as a species–like how we don’t eat our breakfast cereal out of the top of a human skull anymore. That’s definitely one for the “win” column.
According to evidence culled from some recently unearthed human bits, this wasn’t always the case. London’s Natural History got its hands on three 14,700-year-old severed skull-cups it believes were used as drinking bowls, possibly in some kind of ritual. 
The skulls, taken from Gough’s Cave, in Sommerset, England, were fashioned in a similar manner to skull-based drinking cups that have been discovered in areas like Tibet, Fiji, and India. The treatment of the skulls apparently shows too much care to be a simple case of one person drinking another’s delicious brain juices. 
“I think the production of the skull-cups is ritualistic,” said the museum’s Dr. Silvia Bello. “If the purpose was simply to break the skulls to extract the brain to eat it, there are much easier ways to do that.” Sure, any simple zombie could tell you that.

One in Three Russians Thinks Sun Revolves Around Earth

Aristarchus of Samos suggested it in the third century BC. Nicolaus Copernicus really drove the point home about 1,800 years later. And, in case anyone still had forgotten, Sun Ra reminded us in 1965, with The Heliocentric Worlds, volumes one and two. But the people of Russia apparently don’t listen to a heck of a lot of avant-garde jazz. According to a new study, 32 percent of Russians are under the impression that the sun revolves around the earth.

Says Olga Kamenchuk, a spokeswoman for the organization that did the polling, “It’s really quite amazing. All of [the questions] were absolutely obvious… the data speaks of the low levels of education in the country.”

Also on the survey: a question about whether humans and dinosaurs roamed the Earth at the same time. Twenty-nine percent of those surveyed believe they did. The survey polled 1,600 people across the country. The margin of error is 3.4 percent.

How a Dead Elephant Is Consumed In Under Two Minutes [Video]

This is a time lapse of what happens when you leave a dead elephant on the savanna. Yes, it’s like the Lion King, but really gross. Don’t play it if you don’t want to see leopards, hyenas and flies putting all those proteins and carbohydrates back into the ecosystem. More »

This Star Trek-Style Scanner Tells If You’re Healthy Or Not [Medicine]

I never thought I would live to see something like this: A hand held scanner that can detect if a patient is healthy or not just by pointing it at the skin. It seems out of Star Trek, but it is real and it works today. More »

Giant Planet May, May Not Exist at Edge of Solar System

Is there a giant planet four times the size of Jupiter hanging out at the edge of our solar system? The consensus from scientists is a definitive “maybe.”  Two researchers at the University of Louisiana at Lafayette believe that there’s a gas giant lurking in our solar system, a theory they base on the strange pattern of comets in the area.

The phantom planet has been nicknamed Tyche, after a Greek goddess, and it’s been the source of some major controversy–which is to say that a lot of fellow scientists aren’t really buying the theories about a giant ninth planet, at least not with the current evidence available.

Over at Discover Magazine, Phil Plait had this to say, 

I read their papers, and thought the data were interesting but unconvincing. The sample size was too small. A bigger study was done, but again the effects weren’t quite enough to rise to the level of breakthrough.

There you have it, a big, fat scientific “maybe.”

Researchers calculate the amount of information in the world, move on to calculate how much time they wasted on silly calculations

Have you ever wondered how much information there is in the world? No? Well, someone has. In fact, new research by a team at the USC Annenberg School for Communication & Journalism, led by Martin Hilbert, has gone ahead and done some calculations to that effect, and the results, while seemingly trivial, are rather interesting. Turns out that there’s a ton of information in the world, and the rate of its production is ever-increasing. A few fun tidbits: the current capacity for information, including digital and analog devices, is 295 exabytes, and by their metrics, 2002 is considered the start of the digital age. By 2007, around 94 percent of information was stored digitally. The full research is in the February issue of Science Express, and a video describing their methodology is after the break.
