A new cheaper way in creating magnets.
US researchers have created a powerful permanent magnet out of iron and nitrogen, two plentiful cheap materials, as part of a programme to cut the need for ‘rare earth’ metals.
It is only a tiny sample, a film 500nm thick, but it is the real thing.

Advocates of Active SETI say it’s better to put our best foot forward first, before E.T. gets the wrong idea about us from shock jocks and reality TV. As in politics, define ourselves before someone else does it for us. Plus, they contend, they’d already know we’re here anyway.
Two new separate groups of scientists now want to send coded radio messages into the cosmos in hopes of deliberately attracting the attention of intelligent space aliens. Known as Active SETI (Active Search for Extraterrestrial Intelligence), it’s arguably no safer to entice unknown offworlders into our planetary living room than to invite total strangers in for coffee and crullers.
But even if they are totally unsavory, it’s highly likely that an interstellar civilization would already be picking up our electromagnetic leakage and therefore already know we’re here, Douglas Vakoch, President of the San Francisco-based non-profit METI (Messaging Extraterrestrial Intelligence) International, told me.

Nice read.
At the beginning of the movie 50/50, Adam Lerner is diagnosed with neurofibrosarcoma, a cancer of the spine’s nerve tissue. Adam sits in his doctor’s office while the doctor rattles off the word several times, but Adam has no idea what it means, or if there’s anything wrong with him at all. Eventually, his doctor uses the word “cancer,” and Adam’s perspective goes blurry, the doctor’s voice drowned out by a high-pitched ringing.
Many people have had real experiences like this one. Cancer is still one of the scariest words you can hear in a diagnosis. And chances are, you know someone who has heard it—almost 40 percent of adults are diagnosed with some form of it during their lifetime. Every patient’s story is different, and they don’t all have a happy ending. But because of decades of research into how cancer works, patients diagnosed with cancer today have a much better chance of survival than ever before.
Virtual Reality is finally happening after years of existing only in science fiction or as underwhelming prototypes. While Oculus Rift is certainly a big deal due to the financial support from Facebook, there are other compelling options on the market. One particularly impressive bit of hardware is the HTC Vive, which features a variety of great games and immersive motion controls.
The below video showcases several of the most exciting games on the HTC Vive, which headset purchasers will be ready to play as long as they have a gaming PC that meets the minimum requirements to be VR ready.
No longer in the movies.
Specific regions of the brain are specialized in recognizing bodies of animals and human beings. By measuring the electrical activity per cell, scientists from KU Leuven, Belgium, and the University of Glasgow have shown that the individual brain cells in these areas do different things. Their response to specific contours or body shapes is very selective.
Facial recognition has already been the subject of much research. But what happens when we cannot recognize an animal or a human being on the basis of a face, but only have other body parts to go on? The mechanism behind this recognition process is uncharted territory for neuroscientists, says Professor Rufin Vogels of the KU Leuven Laboratory for Neuro- and Psychophysiology.
