Scientists Have Developed a Material So Dark That You Can't See It 238

Posted by samzenpus
from the none-more-black dept.
gbjbaanb writes A British company is developing a new material that's so black it absorbs all but 0.035 percent of the visual light, making it the darkest material ever created. Of course, apart from making album covers, it conducts heat 7 times better than copper and is 10 times stronger than steel. "The nanotube material, named Vantablack, has been grown on sheets of aluminium foil by the Newhaven-based company. While the sheets may be crumpled into miniature hills and valleys, this landscape disappears on areas covered by it. 'You expect to see the hills and all you can see it's like black, like a hole, like there's nothing there. It just looks so strange,' said Ben Jensen, the firm's chief technical officer.

Ancient Bird With Largest Wingspan Yet Discovered 55

sciencehabit writes Fossils unearthed at a construction project in South Carolina belong to a bird with the largest wingspan ever known, according to a new study. The animal measured 6.4 meters from wingtip to wingtip, about the length of a 10-passenger limousine and approaching twice the size of the wandering albatross, today's wingspan record-holder. Like modern-day albatrosses, the newly described species would have been a soaring champ.

Julian Assange Plans Modeling Debut At London Fashion Show 173

An anonymous reader writes with news about a possible new direction for Julian Assange. Julian Assange is expected to make his London Fashion Week debut this September. The Australian WikiLeaks founder will reportedly model for Vivienne Westwood’s son, Ben Westwood, at a fashion show staged at the Ecuadorean Embassy, where he has been seeking refuge for the past two years. He is avoiding extradition to Sweden, where he is wanted for questioning over claims of sex offences. “Julian’s been in the embassy for two years and it’s important that he doesn’t slip into obscurity,” said Ben Westwood. “I want to highlight Julian Assange’s plight. What happened to him is totally unfair.”

Scientists Successfully Grow Full Head of Hair On Bald Man 109

realized writes: "A man with almost no hair on his body has grown a full head of it after a novel treatment by doctors at Yale University. The patient had previously been diagnosed with both alopecia universalis, a disease that results in loss of all body hair, and plaque psoriasis, a condition characterized by scaly red areas of skin. The only hair on his body was within the psoriasis plaques on his head. He was referred to Yale Dermatology for treatment of the psoriasis. The alopecia universalis had never been treated.

After two months on tofacitinib [an FDA-approved arthritis drug] at 10 mg daily, the patient's psoriasis showed some improvement, and the man had grown scalp and facial hair — the first hair he'd grown there in seven years. After three more months of therapy at 15 mg daily, the patient had completely regrown scalp hair and also had clearly visible eyebrows, eyelashes, and facial hair, as well as armpit and other hair, the doctors said."

How do you distinguish between intentional and unintentional changes? How much storage overhead do you need to keep all changes so that you can roll back any unintentional change?

I'm only a rocket scientist, not a CS person, but it seems intuitive to me. If it's an intentional change, then the new version will have a later last-modified date than the back-up. If the hash of the back-up copy made at the time it was written matches a hash calculated at the time of the second back-up, then the integrity of the back-up is confirmed. If the active copy has not been intentionally changed in the interval, and its hash no longer matches the other two, then the active should be discarded in favor of the back-up. I'm sure you can do the mental figuring for the equivalent to detect if the back-up rather than the active has bitrotted.

The challenge arrives if you have *both* intentional and unintentional changes to the same file between successive back-ups. To exclude unintentional changes, you would have to do hashes every time you save/compile/whatever,as well as keep a keystroke log of the edits. Then, you would have to execute the exact same change process on the back-up copy, repeating the process described above. It would be incredibly resource-intensive (essentially having a 'bot duplicate the work you have performed between back-ups), but it would sure be thorough.

Lord, I HOPE this is not an original idea. If I just invented it, and somebody tries to patent it later, you're in for a world of hurt.

US Secret Service Wants To Identify Snark 213

Why not just force Twitter to change TOS to require sarcasm tag?"

Please provide a link to any mainstream working application for Mac OS X that uses Qt. I don't know of a single one because Qt's support for XCode is incredibly poor.

Scott Adams's Plan For Building Giant Energy-Generating Pyramids 107

LoLobey (1932986) writes "Scott Adams has proposed a pyramid project to save the world via energy generation and tourism. Basically build giant pyramids, miles wide and high, in the desert to generate power via chimney effect and photo voltaics with added features for tourism (he's planning ahead for when robots take over all the work and we'll need something to do). He's had a few "Big Ideas" lately (canals, ice bergs, ion energy)."

Printed Circuits as Part of a 3-D Printed Object (Video) 42

Posted by timothy

Affordable 3-D printing is still young; just a few years ago, it would have been nearly impossible to have an arbitrary three-dimensional piece of plastic (or resin, or sometimes metal) created from a software description in a box that fits on your desk. But in the several years the printing of *things* has moved fromquaint, quixotic, futzing-about hobby into something that works (fairly) reliably in ever more garages, schools, and hackerspaces, it's gotten good enough that you can now download and print quite a few objects that are available for download, or scan small items to replicate, or scan your friends to print out as statuettes. However, for the most part, these printed pieces are static, and finished. With care, you can print things like a chain, or even a ball joint, but you're still limited mostly to one basic material at a time. (Printing with multiple colors is getting easier, though.) If you want to print a flashlight or a robot, you'll need to add wires and other circuitry as a separate step. That's what the folks at Rabbit Proto (get it?) are trying to change. With the system they're working on, a filament printer is used to fabricate the object itself, but at the same time, both capacitive and conductive features can be baked -- or rather printed -- right in, with a separate print head. We talked with Alexandre Jais and Manal Dia of Rabbit Proto about how the system works, and why you might want to use it. (Alternate video link.)
