Army Goes Goth With 'Super-Black' Materials



Get ready to break out the eyeliner and the candelabras, because the Army is going goth.


In its latest round of solicitations for small businesses, the Army is asking for proposals for super-black material. That is, material so black that it absorbs 99 percent of all light. But it isn’t really black paint, exactly. The plan is to use either an “antireflective coating or surface treatment process for metals” to absorb stray light “in the ultraviolet, visible, infrared, and far-infrared regions.” This, the Army hopes, will boost the quality of high-resolution cameras, while also cooling down sensitive electronics. Or to put it another way: The Army needs the color black to reflect its icy-cold heart.


Another curious thing is that the program is being run out of the Army’s Program Executive Office Ammunition at the Picatinny Arsenal, a main center for the Pentagon’s experiments in all sorts of weapons: from rifles and tank cannons to directed-energy weapons. But the purpose of the solicitation isn’t much more specific than described. “Simply put, it’s too early yet to speculate on where the technology(s) will go,” Frank Misurelli, an Army spokesman at Picatinny said in a statement provided to Danger Room. ”Possibly in a few months, after an contract has been awarded, more information may become available.”


But for whatever the Army wants to fade to black, it seems that regular black isn’t good enough. This is because most black paint will absorb only around 90-95 percent of light, with the other 5-10 percent reflected back outwards. For a high-resolution camera, that stray light can bounce back into the lens and interfere with the quality of an image. It’s even a problem for NASA’s ultra-deep-space sensors. In the extreme coldness of space, black paint turns a silver-y color, which increases heat and can interfere with infrared-detecting instruments.



But wait, doesn’t black get really hot when hit with light, like wearing black clothes during the summer? The answer is: sorta. Black is really good at absorbing heat, but is also really good at radiating heat away. This is why cooling fins, radiators and engines for cars and trucks are often painted black. In 2011, NASA developed a carbon-nanotube coating that absorbed between 98-99.5 percent of light, depending on the wavelength. Nor do the coating’s thin layers of nanotubes change color in extreme cold. They absorb more light, and help radiate heat away from instruments, keeping them cold.


The Army could go another route. A second option uncovered by Britain’s National Physical Laboratory involves immersing an object in a solution of nickel and sodium for several hours, which blackens the color, and then taking it out and dunking it in nitric acid for a few seconds. According to New Scientist, this creates an alloy pock-marked with tiny microscopic craters that prevent light from bouncing away.


Finally, the Army also hopes to expand the materials to “optical glass surfaces” — camera lenses, in other words — while testing to see whether “it will be able to survive in a military environment.” The material should also come in “multiple surface colors” and be able to “selectively exhibit earth color instead of broadband absorption.” And another hope is to use the materials to absorb water to cool down equipment. See, it’s tough out there being goth, but it doesn’t mean you can’t do it in comfort.

Gifts That Keep Giving (if Not Exploding)


Gregory Tobias/Chemical Heritage Foundation Collections

Ask scientists of a certain age about their childhood memories, and odds are they’ll start yarning about the stink bombs and gunpowder they concocted with their chemistry sets. Dangerous? Yes, but fun.




“Admittedly, I have blown some things up in my time,” said William L. Whittaker, 64, a robotics professor at Carnegie Mellon University who unearthed his first chemistry set, an A. C. Gilbert, in a junkyard around age 8. By 16, he was dabbling in advanced explosives. “There’s no question that I burned some skin off my face,” he recalled.


Under today’s Christmas tree, girls and boys will unwrap science toys of a very different ilk: slime-making kits and perfume labs, vials of a fluff-making polymer called Insta-Snow, “no-chem” chemistry sets (chemical free!), plus a dazzling array of modern telescopes, microscopes and D.I.Y. volcanoes. Nothing in these gifts will set the curtains on fire.


“Basically, you have to be able to eat everything in the science kit,” said Jim Becker, president of SmartLab Toys, who recalled learning the names of chemicals from his childhood chemistry set, which contained substances that have long since been banned from toys.


Some scientists lament the passing of the trial-and-error days that inspired so many careers. “Science kits are a lot less open-ended these days,” said Kimberly Gerson, a science blogger who lives outside Toronto. “Everything is packaged. It’s either ‘yes’ or ‘no.’ If you don’t get the right result, you’ve done it wrong and you’re out of chemicals.”


Others, though, say the new crop of science toys — even with their cartoonish packaging and heavy emphasis on neon goo — actually represent progress. More entertaining, educational and accessible than earlier products, which relied heavily on a child’s inner motivation, these toys may actually help democratize the learning of science and introduce children to scientific methods and concepts at an earlier age.


“I grew up in the 1960s, and a lot of the chemistry sets were kind of boring,” said William Gurstelle, a science and technology writer. “You’d go through the book, and at the end of the experiment you’d get some light precipitate at the bottom of the beaker. Maybe at most it changes color or something.”


Mr. Gurstelle’s books, which include “Whoosh Boom Splat” and “Backyard Ballistics,” teach people how to make dangerous projectiles, like a potato cannon that uses hair spray as launching fluid. But he had high praise for commercial science kits, which show children (among other things) how to make slime.

“Well, that’s a pretty cool thing to have when you’re done,” Mr. Gurstelle said. “You’re not going to really learn to be a chemist from a chemistry set when you’re in seventh grade; you’re just going to be inspired. The point is that new chemistry sets and new toys are just better, because the manufacturers have figured out how to make them more fun.”


Some toy makers, like SmartLab, Mr. Becker’s company, have used this philosophy to give classic toys a makeover. One of SmartLab’s takes on a chemistry set, for instance, is the Extreme Secret Formula Lab, which comes with “squishy-lidded bubble test tubes” and “an abundance of glow-in-the-dark powder.” The game of Mousetrap has been re-envisioned as the Weird and Wacky Contraption Lab, meant to bring out children’s Rube Goldberg talents. And the slot car tracks that Mr. Becker recalls snapping together in his youth have been translated into a robot called ReCon 6.0, which children can program to roam around.

“What we do is give kids the opportunity to learn through problem solving,” Mr. Becker said.


Of course, technology has also remade the experience of learning science. Children may be more likely to click on a science app than to go play outside.

Raging fire guts Kabul market









KABUL, Afghanistan -- Firefighters battled through the night to contain a raging fire that swept through a market in the Afghan capital.

No injuries were reported, but the blaze destroyed hundreds of stores and millions of dollars worth of merchandise, Afghan police and firefighters said at the scene. 


Dealers at the neighboring currency exchange, the city’s largest, said they evacuated cash, computer equipment and records from their shops as the flames approached during the night. But in the morning, the market was jammed with people haggling over thick stacks of notes as smoke billowed overhead.





Col. Mohammed Qasem, general director of the Kabul fire department, said he suspected an electrical short was to blame for the fire. 


Gas canisters used to heat the stores propelled the flames, along with the cloth and clothing sold by many of the vendors, Qasem said. “It made it very big in a short time.”


Firefighters from the Afghan defense department and NATO forces were sent to assist. But the city’s notorious traffic and the market’s narrow lanes made it difficult for responders to maneuver their vehicles, Qasem said.


Abdulrahman, who like many Afghans has only one name, squatted near a fire truck with his head in his hands  as responders aimed a hose at the blackened ruins of a building still smoldering at noon Sunday, more than 12 hours after the fire broke out.


He said the building had contained three shops that he owned and a warehouse full of glassware, crockery and kitchen utensils. 


“I lost everything,” he said.


Shirali Khan complained that police hadn't allowed him to remove the goods from his four clothing stores.


“They thought we were all robbers,” he said.  “There’s only ashes left.”

Reality TV star Bethenny Frankel and husband to separate






NEW YORK (Reuters) – Reality TV star Bethenny Frankel and her husband Jason Hoppy are separating, Frankel announced on Sunday.


“It brings me great sadness to say that Jason and I are separating. This was an extremely difficult decision that, as a woman and a mother, I have to accept as the best choice for our family,” Frankel said in a statement confirmed by her representative.






“We have love and respect for one another and will continue to amicably co-parent our daughter who is and will always remain our first priority. This is an immensely painful and heartbreaking time for us.”


Frankel, 42, and Hoppy married in March of 2010. They have a daughter, Bryn, who was born in May of 2010.


On Sunday, Frankel tweeted, “I am heartbroken. I am sad. We will work through this as a family.”


Frankel first attracted attention in 2008 on the reality show “The Real Housewives of New York City,” which chronicles the exploits of wealthy New York women. She went on to star in two other reality TV shows, “Bethenny Getting Married?” and “Bethenny Ever After…,” both of which centered on the couple’s marriage and child-rearing.


Frankel also founded the Skinnygirl line of cocktails, and has written several diet and self-help books. In 2012 she launched a talk show, “Bethenny,” which is set to air nationally in 2013.

N.Y.U. and Others Offer Shorter Courses Through Medical School





Training to become a doctor takes so long that just the time invested has become, to many, emblematic of the gravity and prestige of the profession.




But now one of the nation’s premier medical schools, New York University, and a few others around the United States are challenging that equation by offering a small percentage of students the chance to finish early, in three years instead of the traditional four.


Administrators at N.Y.U. say they can make the change without compromising quality, by eliminating redundancies in their science curriculum, getting students into clinical training more quickly and adding some extra class time in the summer.


Not only, they say, will those doctors be able to hang out their shingles to practice earlier, but they will save a quarter of the cost of medical school — $49,560 a year in tuition and fees at N.Y.U., and even more when room, board, books, supplies and other expenses are added in.


“We’re confident that our three-year students are going to get the same depth and core knowledge, that we’re not going to turn it into a trade school,” said Dr. Steven Abramson, vice dean for education, faculty and academic affairs at N.Y.U. School of Medicine.


At this point, the effort involves a small number of students at three medical schools: about 16 incoming students at N.Y.U., or about 10 percent of next year’s entering class; 9 at Texas Tech Health Science Center School of Medicine; and even fewer, for now, at Mercer University School of Medicine’s campus in Savannah, Ga. A similar trial at Louisiana State University has been delayed because of budget constraints.


But Dr. Steven Berk, the dean at Texas Tech, said that 10 or 15 other schools across the country had expressed interest in what his university was doing, and the deans of all three schools say that if the approach works, they will extend the option to larger numbers of students.


“You’re going to see this kind of three-year pathway become very prominent across the country,” Dr. Abramson predicted.


The deans say that getting students out the door more quickly will accomplish several goals. By speeding up production of physicians, they say, it could eventually dampen a looming doctor shortage, although the number of doctors would not increase unless the schools enrolled more students in the future.


The three-year program would also curtail student debt, which now averages $150,000 by graduation, and by doing so, persuade more students to go into shortage areas like pediatrics and internal medicine, rather than more lucrative specialties like dermatology.


The idea was supported by Dr. Ezekiel J. Emanuel, a former health adviser to President Obama, and a colleague, Victor R. Fuchs. In an editorial in the Journal of the American Medical Association in March, they said there was “substantial waste” in the nation’s medical education. “Years of training have been added without evidence that they enhance clinical skills or the quality of care,” they wrote. They suggested that the 14 years of college, medical school, residency and fellowship that it now takes to train a subspecialty physician could be reduced by 30 percent, to 10 years.


That opinion, however, is not universally held. Other experts say that a three-year medical program would deprive students of the time they need to delve deeply into their subjects, to consolidate their learning and to reach the level of maturity they need to begin practicing, while adding even more pressure to a stressful academic environment.


“The downside is that you are really tired,” said Dr. Dan Hunt, co-secretary of the Liaison Committee on Medical Education, the accrediting agency for medical schools in the United States and Canada. But because accreditation standards do not dictate the fine points of curriculum, the committee has approved N.Y.U.’s proposal, which exceeds by five weeks its requirement that schools provide at least 130 weeks of medical education.


The medical school is going ahead with its three-year program despite the damage from Hurricane Sandy, which forced NYU Langone Medical Center to evacuate more than 300 patients at the height of the storm and temporarily shut down three of its four main teaching hospitals.


Dr. Abramson of N.Y.U. said that postgraduate training, which typically includes three years in a hospital residency, and often fellowships after that, made it unnecessary to try to cram everything into the medical school years. Students in the three-year program will have to take eight weeks of class before entering medical school, and stay in the top half of their class academically. Those who do not meet the standards will revert to the four-year program.

Terra/MODIS Color Image of Copahue Eruption Plume Across South America











For the first time since 2000, Copahue is erupting, sending an ash plume across southern South America. So far, the eruption is following the same patterns as the activity that ran from July to October 2000. That activity started with phreatic (water-driven) explosions, so it will be interesting to see if this eruption has new juvenile magma involved. Earlier this year, a study of the summit crater lake suggested new magma was intruding under Copahue and the SERNAGEOMIN report mentioned. that seismicity was rising before today’s eruption.


I grabbed the brand new Terra/MODIS imagery for South America and the plume from the Copahue was glorious – stretching over 350 km across Argentina to the east of the volcano. For a sense of scale on the image, the distance between Copahue and the Embalse los Barreales is ~225 km. The plume itself has been reported to be over 9.5 km / 30,000 feet tall.


UPDATE 12/22 5 PM EST: Eruptions reader Kirby pointed me to the SERNAGEOMIN webcam pointed at Copahue — check out the eruption live!


UPDATE 12/22 7 PM EST: ONEMI has not called for any evacuations on the Chilean side of Copahue — this article also has a nice gallery of pictures from the eruption as well.

Iron Butterfly bassist Lee Dorman dies at age 70






LOS ANGELES (AP) — Lee Dorman, the bassist for psychedelic rock band Iron Butterfly, has died at age 70.


Orange County sheriff‘s spokeswoman Gail Krause says Dorman was found dead in a vehicle Friday morning. A coroner’s investigation is under way, but foul play is not suspected.






Krause said Dorman may have been on his way to a doctor’s appointment when he died.


Iron Butterfly was formed and rose to prominence in the late 1960s. Its second album, “In-A-Gadda-Da-Vida,” sold more than 30 million copies, according to the band’s website. The title track’s distinctive notes have been featured in numerous films and TV shows including “The Simpsons,” ”That ’70s Show” and in the series finale of “Rescue Me.”


Douglas Lee Dorman was born in September 1942 and had been living in Laguna Niguel, a coastal city in Southern California, when he died.


A message sent through the band’s website was not immediately returned.

Amazon Book Reviews Deleted in a Purge Aimed at Manipulation





Giving raves to family members is no longer acceptable. Neither is writers’ reviewing other writers. But showering five stars on a book you admittedly have not read is fine.




After several well-publicized cases involving writers buying or manipulating their reviews, Amazon is cracking down. Writers say thousands of reviews have been deleted from the shopping site in recent months.


Amazon has not said how many reviews it has killed, nor has it offered any public explanation. So its sweeping but hazy purge has generated an uproar about what it means to review in an era when everyone is an author and everyone is a reviewer.


Is a review merely a gesture of enthusiasm or should it be held to a higher standard? Should writers be allowed to pass judgment on peers the way they have always done offline or are they competitors whose reviews should be banned? Does a groundswell of raves for a new book mean anything if the author is soliciting the comments?


In a debate percolating on blogs and on Amazon itself, quite a few writers take a permissive view on these issues.


The mystery novelist J. A. Konrath, for example, does not see anything wrong with an author indulging in chicanery. “Customer buys book because of fake review = zero harm,” he wrote on his blog.


Some readers differ. An ad hoc group of purists has formed on Amazon to track its most prominent reviewer, Harriet Klausner, who has over 25,000 reviews. They do not see how she can read so much so fast or why her reviews are overwhelmingly — and, they say, misleadingly — exaltations.


“Everyone in this group will tell you that we’ve all been duped into buying books based on her reviews,” said Margie Brown, a retired city clerk from Arizona.


Once a populist gimmick, the reviews are vital to making sure a new product is not lost in the digital wilderness. Amazon has refined the reviewing process over the years, giving customers the opportunity to rate reviews and comment on them. It is layer after layer of possible criticism.


“A not-insubstantial chunk of their infrastructure is based on their reviews — and all of that depends on having reviews customers can trust,” said Edward W. Robertson, a science fiction novelist who has watched the debate closely.


Nowhere are reviews more crucial than with books, an industry in which Amazon captures nearly a third of every dollar spent. It values reviews more than other online booksellers like Apple or Barnes & Noble, featuring them prominently and using them to help decide which books to acquire for its own imprints by its relatively new publishing arm.


So writers have naturally been vying to get more, and better, notices. Several mystery writers, including R. J. Ellory, Stephen Leather and John Locke, have recently confessed to various forms of manipulation under the general category of “sock puppets,” or online identities used to deceive. That resulted in a widely circulated petition by a loose coalition of writers under the banner, “No Sock Puppets Here Please,” asking people to “vote for book reviews you can trust.”


In explaining its purge of reviews, Amazon has told some writers that “we do not allow reviews on behalf of a person or company with a financial interest in the product or a directly competing product. This includes authors.” But writers say that rule is not applied consistently.


In some cases, the ax fell on those with a direct relationship with the author.


“My sister’s and best friend’s reviews were removed from my books,” the author M. E. Franco said in a blog comment. “They happen to be two of my biggest fans.” Another writer, Valerie X. Armstrong, said her son’s five-star review of her book, “The Survival of the Fattest,” was removed. He immediately tried to put it back “and it wouldn’t take,” she wrote.


In other cases, though, the relationship was more tenuous. Michelle Gagnon lost three reviews on her young adult novel “Don’t Turn Around.” She said she did not know two of the reviewers, while the third was a longtime fan of her work. “How does Amazon know we know each other?” she said. “That’s where I started to get creeped out.”


Mr. Robertson suggested that Amazon applied a broad brush. “I believe they caught a lot of shady reviews, but a lot of innocent ones were erased, too,” he said. He figures the deleted reviews number in the thousands, or perhaps even 10,000.


The explosion of reviews for “The 4-Hour Chef” by Timothy Ferriss shows how the system has evolved from something spontaneous to a means of marketing and promotion. On Nov. 20, publication day, dozens of highly favorable reviews immediately sprouted. Other reviewers quickly criticized Mr. Ferriss, accusing him of buying supporters.


He laughed off those suggestions. “Not only would I never do that — it’s unethical — I simply don’t have to,” he wrote in an e-mail, saying he had sent several hundred review copies to fans and potential fans. “Does that stack the deck? Perhaps, but why send the book to someone who would hate it? That doesn’t help anyone: not the reader, nor the writer.”


As a demonstration of social media’s grip on reviewing, Mr. Ferriss used Twitter and Facebook to ask for a review. “Rallying my readers,” he called it. Within an hour, 61 had complied.


A few of his early reviews were written by people who admitted they had not read the book but were giving it five stars anyway because, well, they knew it would be terrific. “I am looking forward to reading this,” wrote a user posting under the name mhpics.


A spokesman for Amazon, which published “The 4-Hour Chef,” offered this sole comment for this article: “We do not require people to have experienced the product in order to review.”


The dispute over reviews is playing out in the discontent over Mrs. Klausner, an Amazon Hall of Fame reviewer for the last 11 years and undoubtedly one of the most prolific reviewers in literary history.


Mrs. Klausner published review No. 28,366, for “A Red Sun Also Rises” by Mark Hodder. Almost immediately, it had nine critical comments. The first accused it of being “riddled with errors in grammar, spelling and punctuation.” The rest were no more kind. The Harriet Klausner Appreciation Society had struck again.


Mrs. Klausner, a 60-year-old retired librarian who lives in Atlanta, has published an average of seven reviews a day for more than a decade. “To watch her in action is unbelievable,” said her husband, Stanley. “You see the pages turning.”


Mrs. Klausner, who says ailments keep her home and insomnia keeps her up, scoffs at her critics. “You ever read a Harlequin romance?” she said. “You can finish it in one hour. I’ve always been a speed reader.” She has a message for her naysayers: “Get a life. Read a book.”


More than 99.9 percent of Mrs. Klausner’s reviews are four or five stars. “If I can make it past the first 50 pages, that means I like it, and so I review it,” she said. But even Stanley said, “She’s soft, I won’t deny that.”


The campaign against Mrs. Klausner has pushed down her reviewer ratings, which in theory makes her less influential. But when everything is subject to review, the battle is never-ending.


Ragan Buckley, an aspiring novelist active in the campaign against Mrs. Klausner under the name “Sneaky Burrito,” is a little weary. “There are so many fake reviews that I’m often better off just walking into a physical store and picking an item off the shelf at random,” she said.
