Lindsey Kaufman writes in the Washington Post that despite its obvious problems, the open-office model has continued to encroach on workers across the country with about 70 percent of US. offices having no or low partitions. Silcon Valley has led the way with Facebook CEO Mark Zuckerberg enlisting famed architect Frank Gehry to design the largest open floor plan in the world, housing nearly 3,000 engineers with a single room, stretching 10 acres, where everyone will sit in the open with moveable furniture. Michael Bloomberg was an early adopter of the open-space trend, saying it promoted transparency and fairness. Bosses love the ability to keep a closer eye on their employees, ensuring clandestine porn-watching, constant social media-browsing and unlimited personal cellphone use isn’t occupying billing hours. But according to Kaufman employers are getting a false sense of improved productivity with a 2013 study showing that many workers in open offices are frustrated by distractions that lead to poorer work performance. Nearly half of the surveyed workers in open offices said the lack of sound privacy was a significant problem for them and more than 30 percent complained about the lack of visual privacy. The New Yorker, in a review of research on this nouveau workplace design, determined that the benefits in building camaraderie simply mask the negative effects on work performance. While employees feel like they’re part of a laid-back, innovative enterprise, the environment ultimately damages workers’ attention spans, productivity, creative thinking, and satisfaction says Kaufman. "Though multitasking millennials seem to be more open to distraction as a workplace norm, the wholehearted embrace of open offices may be ingraining a cycle of underperformance in their generation," writes Maria Konnikova. "They enjoy, build, and proselytize for open offices, but may also suffer the most from them in the long run."

Nick Szabo writes that when we use web services, we are relying on an architecture based on full trust in an unknown "root" administrator, who can control everything that happens on the server. They can read, alter, delete, or block any data on that computer at will. Even data sent encrypted over a network is eventually unencrypted and ends up on a computer controlled in this total way. With current web services we are fully trusting, in other words we are fully vulnerable to, the computer, or more specifically the people who have access to that computer, both insiders and hackers, to faithfully execute our orders, secure our payments, and so on. Compare this architecture to traditional commercial protocols, such as ticket-selling at a movie theater, that distribute a transaction so that no employee can steal money or resources undetected. There is no "root administrator" at a movie theater who can pocket your cash undetected. On the Internet, instead of securely and reliably handing over cash and getting our goods or services, or at least a ticket, we have to fill out forms and make ourselves vulnerable to identity theft in order to participate in e-commerce.

Recently a developing technology, often called "the block chain", is starting to change this. A block chain computer is a virtual computer, a computer in the cloud, shared across many traditional computers and protected by cryptography and consensus technology. A block-chain computer, in sharp contrast to a web server, is shared across many such traditional computers controlled by dozens to thousands of people. By its very design each computer checks each other's work, and thus a block chain computer reliably and securely executes our instructions up to the security limits of block chain technology, which is known formally as anonymous and probabilistic Byzantine consensus (sometimes also called Nakamoto consensus). Instead of the cashier and ticket-ripper of the movie theater, the block chain consists of thousands of computers that can process digital tickets, money, and many other fiduciary objects in digital form. "I think we see every week now somewhere between one and three entrepreneurs come in with blockchain ideas," says Chris Dixon. "There's definitely some momentum behind it."

Spaceflight has faded from American consciousness even as our performance in space has reached a new level of accomplishment. In the past decade, America has become a truly, permanently spacefaring nation. All day, every day, half a dozen men and women, including two Americans, are living and working in orbit, and have been since November 2000. Charles Fishman has a long, detailed article about life aboard the ISS in The Atlantic that is well worth the read where you are sure to learn something you didn't already know about earth's permanent outpost in space. Some excerpts:

The International Space Station is a vast outpost, its scale inspiring awe even in the astronauts who have constructed it. From the edge of one solar panel to the edge of the opposite one, the station stretches the length of a football field, including the end zones. The station weighs nearly 1 million pounds, and its solar arrays cover more than an acre. It’s as big inside as a six-bedroom house, more than 10 times the size of a space shuttle’s interior. Astronauts regularly volunteer how spacious it feels. It’s so big that during the early years of three-person crews, the astronauts would often go whole workdays without bumping into one another, except at mealtimes.

On the station, the ordinary becomes peculiar. The exercise bike for the American astronauts has no handlebars. It also has no seat. With no gravity, it’s just as easy to pedal furiously, feet strapped in, without either. You can watch a movie while you pedal by floating a laptop anywhere you want. But station residents have to be careful about staying in one place too long. Without gravity to help circulate air, the carbon dioxide you exhale has a tendency to form an invisible cloud around your head. You can end up with what astronauts call a carbon-dioxide headache.

Even by the low estimates, it costs $350,000 an hour to keep the station flying, which makes astronauts’ time an exceptionally expensive resource—and explains their relentless scheduling: Today’s astronauts typically start work by 7:30 in the morning, Greenwich Mean Time, and stop at 7 o’clock in the evening. They are supposed to have the weekends off, but Saturday is devoted to cleaning the station—vital, but no more fun in orbit than housecleaning down here—and some work inevitably sneaks into Sunday.

Life in space is so complicated that a lot of logistics have to be off-loaded to the ground if astronauts are to actually do anything substantive. Just building the schedule for the astronauts in orbit on the U.S. side of the station requires a full-time team of 50 staffers.

Almost anyone you talk with about the value of the Space Station eventually starts talking about Mars. When they do, it’s clear that we don’t yet have a very grown-up space program. The folks we send to space still don’t have any real autonomy, because no one was imagining having to “practice” autonomy when the station was designed and built. On a trip to Mars, the distances are so great that a single voice or e‑mail exchange would involve a 30-minute round-trip. That one change, among the thousand others that going to Mars would require, would alter the whole dynamic of life in space. The astronauts would have to handle things themselves.

That could be the real value of the Space Station—to shift NASA’s human exploration program from entirely Earth-controlled to more astronaut-directed, more autonomous. This is not a high priority now; it would be inconvenient, inefficient. But the station’s value could be magnified greatly were NASA to develop a real ethic, and a real plan, for letting the people on the mission assume more responsibility for shaping and controlling it. If we have any greater ambitions for human exploration in space, that’s as important as the technical challenges. Problems of fitness and food supply are solvable. The real question is what autonomy for space travelers would look like—and how Houston can best support it. Autonomy will not only shape the psychology and planning of the mission; it will shape the design of the spacecraft itself.

Phys.org reports that in a new paper accepted by the journal Astroparticle Physics, Robert Ehrlich, a recently retired physicist from George Mason University, claims that the neutrino is very likely a tachyon or faster-than-light particle. Ehrlich's new claim of faster-than-light neutrinos is based on a much more sensitive method than measuring their speed, namely by finding their mass. The result relies on tachyons having an imaginary mass, or a negative mass squared. Imaginary mass particles have the weird property that they speed up as they lose energy – the value of their imaginary mass being defined by the rate at which this occurs. According to Ehrlich, the magnitude of the neutrino's imaginary mass is 0.33 electronvolts, or 2/3 of a millionth that of an electron. He deduces this value by showing that six different observations from cosmic rays, cosmology, and particle physics all yield this same value within their margin of error. One check on Ehrlich's claim could come from the experiment known as KATRIN, which should start taking data in 2015. In this experiment the mass of the neutrino could be revealed by looking at the shape of the spectrum in the beta decay of tritium, the heaviest isotope of hydrogen.p

But be careful. There have been many such claims, the last being in 2011 when the "OPERA" experiment measured the speed of neutrinos and claimed they travelled a tiny amount faster than light. When their speed was measured again the original result was found to be in error – the result of a loose cable no less. "Before you try designing a "tachyon telephone" to send messages back in time to your earlier self it might be prudent to see if Ehrlich's claim is corroborated by others."

Dahlia Lithwick reports that a panel of the 4th Circuit Court of Appeals has voted to strike down a highly controversial North Carolina law requiring doctors and ultrasound technicians to perform an ultrasound, display the image of the sonogram, and specifically describe the fetus to any pregnant woman seeking an abortion, even if the woman actively “averts her eyes” and “refuses to hear.” In July 2011, the North Carolina General Assembly passed the Woman’s Right to Know Act over then-Gov. Beverly Perdue’s veto. One provision of the law, the “Display of Real-Time View Requirement,” forces doctors or technicians to perform an ultrasound on any woman seeking an abortion at least four but not more than 72 hours before the abortion is to take place. They must show the sonogram so that the woman can see it and describe the fetus in detail, “including the presence, location, and dimensions of the unborn child within the uterus and the number of unborn children depicted.” Doctors who violate the act are liable for damages and may lose their licenses to practice in North Carolina. A lower federal court found that the Display of Real-Time View Requirement violated physicians’ First Amendment rights to free speech (PDF), and the three-judge panel affirmed a lower court’s determination that the law is a compelled speech provision that violates the First Amendment rights of providers. “The requirement is quintessential compelled speech," wrote Judge J. Harvie Wilkinson III, a conservative judge who was shortlisted for John Roberts’ seat as Chief Justice of the Supreme Court. "It forces physicians to say things they otherwise would not say. Moreover, the statement compelled here is ideological; it conveys a particular opinion. The state freely admits that the purpose and anticipated effect of the Display of Real-Time View Requirement is to convince women seeking abortions to change their minds or reassess their decisions.”

Canoe Tech reports that M&M sorting machines are a popular project for people who like combining electronics, programming and machine building. Most of them send a single M&M down a chute to a simple color sensor where the color sensor will then take a second or two to figure out the color. A servo motor will then rotate a chute that will direct the M&M into the correct pot. But a new project created by the nameless blogger behind the reviewmylife blog, that uses an iPhone 5s as its brain is capable of sensing different colors and so can "sort" the M&Ms as they fall past. The iPhone communicates the information via Bluetooth to an Arduino board, which in turn fires off the correct electro magnet controlled gate. One practical application of the sorter could be creating a bowl of M&Ms - with all the brown ones removed. According to Dan and Chip Heath, that's just what rock band Van Halen demand in one of the riders to their standard contract. The band’s “M&M clause” was written into its contract to serve a very specific purpose. It was called Article 126, and it read as follows: “There will be no brown M&M’s in the backstage area, upon pain of forfeiture of the show, with full compensation.” The article was buried in the middle of countless technical specifications. When David Lee Roth would arrive at a new venue, he’d immediately walk backstage and glance at the M&M bowl. If he saw a brown M&M, he’d demand a line check of the entire production. “Guaranteed you’re going to arrive at a technical error,” said Roth. “They didn’t read the contract Sometimes it would threaten to just destroy the whole show.”

For most city-dwellers, the elevator is an unremarkable machine that inspires none of the passion or interest that Americans afford trains, jets, and even bicycles. But according to Daniel Wilk the automobile and the elevator have been locked in a “secret war” for over a century, with cars making it possible for people to spread horizontally, encouraging sprawl and suburbia, and elevators pushing them toward life in dense clusters of towering vertical columns.

Elevators first arrived in America during the 1860s, in the lobbies of luxurious hotels, where they served as a plush conveyance that saved the well-heeled traveler the annoyance of climbing stairs. It wasn’t until the 1870s, when elevators showed up in office buildings, that the technology really started to leave a mark on urban culture. Business owners stymied by the lack of available space could look up and see room for growth where there was previously nothing but air—a development that was particularly welcome in New York, where a real estate crunch in Manhattan’s business district had, for a time, forced city leaders to consider moving the entire financial sector uptown. Advances in elevator technology combined with new steel frame construction methods to push the height limits of buildings higher and higher. In the 1890s, the tallest building in the world was the 20-story Masonic Temple in Chicago. By 1913, when hydraulic elevators had been replaced with much speedier and more efficient electrical ones, it was the 55-story Woolworth Building in New York, still one of the one-hundred tallest buildings in the United States as well as one of the twenty tallest buildings in New York City. "If we didn't have elevators," says Patrick Carrajat, the founder of the Elevator Museum in New York, "we would have a megalopolis, one continuous city, stretching from Philadelphia to Boston, because everything would be five or six stories tall."

But the elevator did more than make New York the city of skyscrapers, it changed the way we live. “The elevator played a role in the profound reorganization of the building,” writes Andreas Bernard. That means a shift from single-family houses and businesses to apartments and office buildings. “Suddenly . . . it was possible to encounter strangers almost anywhere.” The elevator, in other words, made us more social — even if that social interaction often involved muttered small talk and staring at doors. Elevators also reinforced a social hierarchy; for while we rode the same elevators, those who rode higher lived above the fray. "It put the “Upper” into the East Side. It prevented Fifth Avenue from becoming Wall Street," writes Stephen Lynch. "It made “penthouse” the most important word in real estate."

Kitsap Sun reports at Military.com that the USS Ranger, a 1,050-foot-long, 56,000-ton Forrestal-class aircraft carrier, is being towed from the inactive ship maintenance facility at Puget Sound for a 3,400-mile, around-Cape Horn voyage to a Texas dismantler who acquired the Vietnam-era warship for a penny for scrap metal. “Under the contract, the company will be paid $0.01. The price reflects the net price proposed by International Shipbreaking, which considered the estimated proceeds from the sale of the scrap metal to be generated from dismantling,” said officials for NAVSEA. “[One cent] is the lowest price the Navy could possibly have paid the contractor for towing and dismantling the ship.”

The Ranger was commissioned Aug. 10, 1957, at Norfolk Naval Shipyard and decommissioned July 10, 1993, after more than 35 years of service. It was stricken from the Naval Vessel Register on March 8, 2004, and redesignated for donation. After eight years on donation hold, the USS Ranger Foundation was unable to raise the funds to convert the ship into a museum or to overcome the physical obstacles of transporting the ship up the Columbia River to Fairview, Oregon. As a result, the Ranger was removed from the list of ships available for donation and designated for dismantling. The Navy, which can't retain inactive ships indefinitely, can't donate a vessel unless the application fully meets the Navy's minimum requirements. The Ranger had been in pristine condition, but for a week in August volunteers from other naval museums were allowed to remove items to improve their ships. The Ranger was in a slew of movies and television shows, including "The Six Million Dollar Man," "Flight of the Intruder" and "Star Trek IV: The Voyage Home" where it stood in for the USS Enterprise carrier. But the Ranger’s most famous role was in the 1980’s Tom Cruise hit, "Top Gun." “We would have liked to have seen it become a museum, but it just wasn’t in the cards,” Navy spokesman Chris Johnson told Fox. “But unfortunately, it is a difficult proposition to raise funds. The group that was going to collect donations had a $35 million budget plan but was only able to raise $100,000.”

Nicholas St. Fluer reports at The Atlantic that according to researchers, our convenient, sedentary way of life is making our bones weak foretelling a future with increasing fractures, breaks, and osteoporosis. For thousands of years, hunter-gatherers trekked on strenuous ventures for food with dense skeletons supporting their movements and a new study pinpoints the origin of weaker bones at the beginning of the Holocene epoch roughly 12,000 years ago, when humans began adopting agriculture. “Modern human skeletons have shifted quite recently towards lighter—more fragile, if you like—bodies. It started when we adopted agriculture. Our diets changed. Our levels of activity changed,” says Habiba Chirchir, A second study attributes joint bone weakness to different levels of physical activity in ancient human societies, also related to hunting versus farming.

The team scanned circular cross-sections of seven bones in the upper and lower limb joints in chimpanzees, Bornean orangutans and baboons. They also scanned the same bones in modern and early modern humans as well as Neanderthals, Paranthropus robustus, Australopithecus africanus and other Australopithecines. They then measured the amount of white bone in the scans against the total area to find the trabecular bone density. Crunching the numbers confirmed their visual suspicions. Modern humans had 50 to 75 percent less dense trabecular bone than chimpanzees, and some hominins had bones that were twice as dense compared to those in modern humans. Both studies have implications for modern human health and the importance of physical activity to bone strength. “The lightly-built skeleton of modern humans has a direct and important impact on bone strength and stiffness,” says Tim Ryan. That's because lightness can translate to weakness—more broken bones and a higher incidence of osteoporosis and age-related bone loss. The researchers warn that with the deskbound lives that many people lead today, our bones may have become even more brittle than ever before. “We are not challenging our bones with enough loading," says Colin Shaw, "predisposing us to have weaker bones so that, as we age, situations arise where bones are breaking when, previously, they would not have."

Duane D. Stanford writes at Bloomberg that Coca-Cola's Atlanta Headquarters is the latest big campany to ditch its old-style voice mail, which requires users to push buttons to scroll through messages and listen to them one at a time. The change went into effect this month, and a standard outgoing message now throws up an electronic stiff arm, telling callers to try later or use “an alternative method” to contact the person. Techies have predicted the death of voice mail for years as smartphones co-opt much of the office work once performed by telephones and desktop computers. Younger employees who came of age texting while largely ignoring voice mail are bringing that habit into the workforce. “People north of 40 are schizophrenic about voice mail,” says Michael Schrage. “People under 35 scarcely ever use it.” Companies are increasingly combining telephone, e-mail, text and video systems into unified Internet-based systems that eliminate overlap. “Many people in many corporations simply don’t have the time or desire to spend 25 minutes plowing through a stack of 15 to 25 voice mails at the end or beginning of the day,” says Schrage, In 2012, Vonage reported its year-over-year voicemail volumes dropped 8%. More revealing, the number of people bothering to retrieve those messages plummeted 14%. More and more personal and corporate voicemail boxes now warn callers that their messages are rarely retrieved and that they’re better off sending emails or texts. "The truly productive have effectively abandoned voicemail, preferring to visually track who’s called them on their mobiles," concludes Schrage. "A communications medium that was once essential has become as clunky and irrelevant as Microsoft DOS and carbon paper."
