It turns out that the brain, when stimulated, may not look like a frying egg after all. According to MIT's Technology Review, neuroscientists are using "two photon microscopy" to visualize chemical activity in the brains of laboratory animals. Far more powerful than MRI scanning, this process can focus on individual cells and molecules.
OhGizmo says a device like this may be available at a local hardware store at some point in the future, but we're not throwing away our electric drill just yet.
Researchers at Tel Aviv University have reported developing a microwave drill that can cut through concrete. Instead of a traditional bit, the drill uses a needle-like antenna that emits the radiation and can be developed far less expensively than a laser.
While Stephen Hawking contemplates the future of our existence, other scientists are taking some concrete steps toward ensuring it--such as creating another universe.
Arstechnica notes that Japanese physicists are apparently serious about an experiment to create a "baby universe" in the lab. As nutty as it may sound, the project is based in part on an established phenomenon known as the Higgs field--which, as everyone knows, involves such elements as false vacuums and Z bosons.
Needless to say, all of this is well beyond the reach of our puny intellect. But it still makes for some interesting … Read more
An international team of scientists believes that, given the right conditions, it may be possible to revive the woolly mammoth, according to the U.K.'s Times Online.
Well, sort of.
These post-"Jurassic Park" years have seen plenty of talk about using cutting-edge biotechnology to bring the fuzzy elephant cousins back to life (and even start up Siberian safari parks), but this recent announcement appears to be more than theoretical. Experimentation on mice revealed that the male specimens' sperm could potentially still be viable after years in a frozen state, and the scientists believe this could have … Read more
If you've never seen anything wrong with handing your toddler endless bottles of grape juice, you could eventually find your child with Early Childhood Caries (ECC), a kind of tooth decay found on baby teeth. The cavities are caused by prolonged exposure to sweetened juices and tend to be overlooked by parents until the pain becomes so severe that the only option for the toddlers--often under the age of 4--is sedation and extraction.
Good thing technology can come to the rescue (again).
A specially outfitted digital camera can now be used to take pictures of a toddler's teeth … Read more
It's summertime, and that means air shows: vintage planes, military exhibitions and homemade flying machines. But not everyone lives in areas that feature such displays, so Aviation Videos--a site run by Iowa City's Alexis Park Inn, "the Midwest's only aviation-themed all-suites hotel"--provides the next best thing with an impressive collection of videos taken at various locations around the world.
Howl @ The Moon has passed along a great real estate tip, a government auction for an atoll 700 miles southwest of Hawaii. But before you jump at this deal, offered by the GSA's Office of Property Disposal, check the fine print: It apparently was the site of thermonuclear explosives testing by the U.S. military at the height of the Cold War.
If you do decide to buy the islands anyway, at least you'll know why the pineapple in your mai tai is glowing in the dark.
Ever wonder what the sharpest human-made object looks like under a super-high-powered microscope? Well, no, we'd never thought about it either, until we came across this post titled "Sharpest Manmade Thing." Physics News Graphics, published by the American Institute of Physics, has posted a photograph taken with a field ion microscope that shows a "very sharp" tungsten needle, right down to individual atoms.
If you've ever wondered how whales end up in the Hudson River or San Francisco Bay, this post might be of particular interest. Information Aesthetics today posted an item on a "unique visualization method" that tracks the behavior of large sea-going mammals.
We're not sure, however, if it's the easiest diagram to understand. Among the instructions: "A pattern of chevrons on the top surface of the ribbon reveals travel direction & gives an additional orientation cue. The sawtooth's amplitude on top of the ribbon reveals the amount of angular acceleration at any given … Read more
SAN JOSE, Calif.--The roughly 20 pigeons released Tuesday from the roof of the San Jose Museum of Art weren't ordinary, sidewalk food-pecking birds. Each was strapped with a special backpack containing a GPS device, GSM unit with small antennas, temperature sensor, pollution sensor and more.
Beatriz da Costa, a professor at the University of California, Irvine, hopes to gather pollution data from the pigeons that fly up to 300 feet with her project called "PigeonBlog." The study is not scientific, nor does it claim to be. Two students who specialize in computer and engineering studies have … Read more
