Say you were curious about what happened when a human brain came into prolonged contact with a strong magnetic field. To find an answer, you might learn more about the nature of magnetism and the biology of the brain and make some hypotheses. Later, you'd run some experiments using dead tissue, or perhaps live animal models. This is because you are a good person.
If you were Thomas Edison, on the other hand, you'd find the nearest street urchin and keep him inside a giant electromagnet. It's OK, though, science writers would later say, because there turned out not to be much of an effect, and, anyway, the boy liked it.
Many years ago, Mr. Thomas Edison made the following interesting experiment in his laboratory. Wishing to see what, if any, influence is produced by the passage of strong magnetic flux through the brain, he kept a boy for a long time inside a huge electro-magnet with his head placed between the poles so that the flux passed directly through his brain. If now a magnet is capable of producing any effect whatever on the body it should certainly have done it in this case. But as far as could be seen no effect whatever was felt by the boy. When asked privately how he felt he replied confidentially, "The experiment is bully. I am all right in the magnet. I like to be here for I do not have to work while the experiment is going on and I can take a nap occasionally. But don't tell Mr. Edison. I hope he will keep me here for a long time."

Researchers at UC Riverside and Centro de Investigación Científica y de Educación Superior de Ensenada have published a paper describing their ongoing success in setting a “transparent nanocrystalline yttria-stabilized-zirconia” into patients’ skulls, which reveal the patients’ brains so that the patients’ brains can be zapped with therapeutic lasers.
One million miles from Earth, hanging in space between Earth’s gravitational pull and the sun’s, is the DSCOVR satellite and NASA’s incredible EPIC camera. Every two hours, EPIC takes a photo of Earth “to monitor ozone and aerosol levels in Earth’s atmosphere, cloud height, vegetation properties and the ultraviolet reflectivity of Earth.” The above video […]
In Botswana, conservation scientists from the University of New South Wales are painting eyes on the rear ends of cattle in an effort to deter lions from eating them. As the lions’ protected habitats shrink, they move closer to human settlements. In Botswana, the lions attack the livestock that the subsistence farmers count on. That […]
3D printers are hot, but they’re also pricey. While the prospect of cranking out everything we can dream up is enticing, cost is often one factor that keeps us from jumping onto the 3D printing train.Now, thanks to M3D, that doesn’t have to be the case. You can now get its flagship 3D printer–plus four reels of filaments–for just […]
It’s no secret that technology is changing the way we all work—but it’s also transforming the way we play. The games of today look nothing like those of 10 or even 20 years ago: these days it’s all about mobile and 3D. And now you can learn to design 3D mobile games with the Intro to Unity 3D Game […]
