Ask Slashdot: Have You Tried a Standing Desk? 147 147

An anonymous reader writes: Evidence is piling up that sitting down all day is really bad for you. I work primarily from home, and as I grow older, I'm starting to worry about long term consequences to riding a desk full-time. We talked about this a few years ago, but the science has come a long way since then, and so have the options for standing desks. My questions: do you use a standing desk? What kind of setup do you have? There are a lot of options, and a lot of manufacturers. Further studies have questioned the wisdom of standing all day, so I've been thinking about a standing/sitting combo, and just switching every so often. If you do this, do you have time limits or a particular frequency with which you change from sitting to standing?

I'm also curious about under-desk treadmills — I could manage slowly walking during parts of my work, and the health benefits are easy to measure. Also, any ergonomic tips? A lot of places seem to recommend: forearms parallel to the ground, top of monitor at eye level, and a pad for under your feet. Has your experience been the same? Those of you who have gone all-out on a motorized setup, was it worth the cost? The desks are dropping in price, but I can still see myself dropping upward of $1k on this, easily.

Pluto Probe Back To Normal, Cause of Snafu Found 54 54

Tablizer writes: NASA has provided an update to the problem with the New Horizons probe that will fly by Pluto next week. "The investigation into the anomaly that caused New Horizons to enter "safe mode" on July 4 has concluded that no hardware or software fault occurred on the spacecraft. The underlying cause of the incident was a hard-to-detect timing flaw in the spacecraft command sequence that occurred during an operation to prepare for the close flyby. No similar operations are planned for the remainder of the Pluto encounter.

Researchers Study "Harbingers of Failure," Consumers Who Habitually Pick Losers 223 223

AmiMoJo writes: Is your favorite TV show always getting cancelled? Did you love Crystal Pepsi? Were you an early adopter of the Zune? If you answered yes to these questions, researchers say you might be a "Harbinger of Failure." In a study published in the Journal of Marketing Research, researchers identified a group of consumers whose preferences can predict products that will fail. “Certain customers systematically purchase new products that prove unsuccessful,” wrote the study authors. “Their early adoption of a new product is a strong signal that a product will fail.”

Chinese Zoo Animals Monitored For Earthquake Prediction 27 27

An anonymous reader writes: Seismologists in Nanjing have set up seven observation centers at zoos and animal parks in the region to see if animals can predict when an earthquake may strike. At least three kinds of animals in the earthquake stations should corroborate each other when bizarre behavior occurs, said Zhao Bing, head of Nanjing earthquake monitoring. Discovery reports: "According to one English-language Chinese news outlet, 'At Banqiao ecological park the behavior of around 200 pigs, 2,000 chickens, and fish in a 15-hectare pond are closely monitored to detect signals of an earthquake. Breeders here create daily reports regarding animal behavior for Nanjing's seismological departments.' The news report noted that the park relies 'mainly on employees closely watching the animals' for seismological significance."

Checking Mammoth DNA Against Elephants Hints At How They Got Hairy 18 18

An anonymous reader writes: A new study on mammoth DNA comparing the hairy animals to their cousins, the Asian and African elephants, has isolated what genes separate it from its warm-weather cousins. The study found that genes controlling skin and hair development, fat metabolism, insulin signaling, and skull shape, differed from today's contemporary elephant species. "They have this weird hump on their back, which is thought to be something like a camel hump — sort of a fat deposit that stored water and energy for the cold, dark winters," says Vincent Lynch, an evolutionary biologist at the University of Chicago.

Seahorse Tails Could Inspire New Generation of Robots 15 15

An anonymous reader writes: Researchers at Clemson University have studied the makeup of seahorse tails and rendered its mechanics using 3D-printing in an effort to provide flexibility to stiff robots. Unlike most creatures, seahorse's tail is made of square prisms. Michael Porter, assistant professor in mechanical engineering at Clemson University said, "Almost all animal tails have circular or oval cross-sections—but not the seahorse's. We wondered why. We found that the squared-shaped tails are better when both grasping and armor functions are needed."

Russian Progress Cargo Ship Docks With Space Station 45 45

An anonymous reader writes: An unmanned Russian cargo ship has successfully docked with the International Space Station. The successful launch, rendezvous and docking came after two resupply failures. A Progress launched in April spun out of control and a week ago, a SpaceX Falcon 9 rocket disintegrated, destroying a supply ship loaded with supplies and equipment. "Crew reports, 'feels like Christmas in July,'" the International Space Station tweeted.

Scientists Look For Patterns In North Carolina Shark Attacks 88 88

HughPickens.com writes: The Washington Post reports that there have been seven recent shark attacks in North Carolina. Scientists are looking for what might be luring the usually shy sharks so close to shore and among the swimmers they usually avoid. It's an unusual number of attacks for a state that recorded 25 attacks between 2005 and 2014. Even with the recent incidents, researchers emphasize that sharks are a very low-level threat to humans, compared with other forms of wildlife. Bees, for example, are much more dangerous. And swimming itself is hazardous even without sharks around.

George Burgess, director of the International Shark Attack File at the University of Florida's Florida Museum of Natural History, speculates that several environmental factors could be pushing sharks to congregate in the Outer Banks. It is a warm year, and the water has a higher level of salinity because of a low-level drought in the area. Also, a common species of forage fish — menhaden — has been abundant this year and might have attracted more sharks to the area. Burgess also says some fishermen put bait in the water near piers, which could lure the predators closer to shore; two of the encounters took place within 100 yards of a pier. "That's a formula for shark attacks," Burgess says of these conditions, taken together. "Now, does that explain seven attacks in three weeks? No, it doesn't."

Why Electric Vehicles Aren't More Popular 626 626

An anonymous reader writes: Ars takes a look at a recent report from the National Academy of Sciences into the reasons why more people aren't driving electric vehicles. Of course infrastructure issues are a part of it — until charging stations are ubiquitous, the convenience factor for using a gas-powered car will weigh heavily on consumers's minds. (This despite the prevalence of outlets at home and work, where the vast majority of charging will be done even with better infrastructure.) But other reasons are much more tractable. Simply giving somebody experience with an EV tends to make the fog of mystery surrounding them dissipate, and the design of the car counts for a lot, too. It turns out car buyers don't want their EVs to look different from regular cars.

3-D Ultrasonic Fingerprint Scanning Could Strengthen Smartphone Security 30 30

Zothecula sends news that researchers from the University of California are developing new fingerprint scanning technology that could one day enhance the security of mobile devices. The new technique scans a fingertip in 3D, capturing the tiny ridges and valleys that make up a fingerprint, as well as the tissue beneath the surface. This guards against attackers unlocking a device with an image of the fingerprint, or by attempting to dust the scanner. The basic concepts behind the researchers’ technology are akin to those of medical ultrasound imaging. They created a tiny ultrasound imager, designed to observe only a shallow layer of tissue near the finger’s surface. "Ultrasound images are collected in the same way that medical ultrasound is conducted," said [Professor David] Horsley. "Transducers on the chip’s surface emit a pulse of ultrasound, and these same transducers receive echoes returning from the ridges and valleys of your fingerprint’s surface." The basis for the ultrasound sensor is an array of MEMS ultrasound devices with highly uniform characteristics, and therefore very similar frequency response characteristics. ... To fabricate their imager, the group employed existing microelectromechanical systems (MEMS) technology, which smartphones rely on for such functions as microphones and directional orientation. They used a modified version of the manufacturing process used to make the MEMS accelerometer and gyroscope found in the iPhone and many other consumer electronics devices.

Common Medications Sway Moral Judgment 121 121

sciencehabit sends news that two commonly-prescribed drugs have been shown to influence how the human brain makes moral decisions. Citalopram is an SSRI used to treat depression, and levodopa is often used to combat Parkinson's disease. A new study (abstract) asked subjects to set a monetary value on receiving painful electric shocks — for themselves and for others (e.g. "Would you rather endure seven shocks to earn $10 or 10 shocks to earn $15?"). The study found that subjects on citalopram (which affects serotonin levels) were willing to give up more money to reduce shocks, both for themselves and others. Those on levodopa (which affects dopamine levels) made people just as willing to shock others as they were to shock themselves, when those on a placebo tended to be more reluctant to shock others. [Neuroscientist Molly] Crockett says those effects could suggests multiple underlying mechanisms. For example, excess dopamine might make our brain's reward system more responsive to the prospect of avoiding personal harm. Or it could tamp down our sense of uncertainty about what another person is experiencing, making us less hesitant to dole out pain. Serotonin, meanwhile, appeared to have a more general effect on aversion to harm, not just a heightened concern for another person. Such knowledge could eventually develop drugs that address disorders of social behavior, she says.

Russian Cargo Ship Successfully Makes Orbit, Will Supply ISS 50 50

An anonymous reader writes: Early this morning, a Russian Soyuz rocket successfully launched from the Baikonur Cosmodrome in Kazakhstan. The rocket carried a Progress capsule containing 2,700kg of supplies for the International Space Station. It's a much-needed victory after a series of launch failures that saw ISS resupply missions from Orbital ATK, Russia, and SpaceX end in failure. "The station, a joint project involving 15 nations which is staffed by a crew of six astronauts and cosmonauts, currently has a four-month supply of food and water, NASA said. The arrival of the Russian cargo ship, and the planned launch of a Japanese HTV freighter in August, should replenish the station's pantries through the end of the year, NASA said. Friday's successful launch clears the way for three new crew members to fly to the station later this month."

The Science of 4th of July Fireworks 40 40

StartsWithABang writes: There are few things as closely associated with American independence as our willingness and eagerness to celebrate with fiery explosions. I refer, of course, to the unique spectacle of fireworks, first developed nearly a millennium ago halfway across the world. But these displays don't happen by themselves; there's an intricate art and science required to deliver the shows we all expect. So what's the science behind fireworks? Here's the physics (and a little chemistry) behind their height, size, shape, color and sound, just in time for July 4th!

Rocket Labs Picks New Zealand For Its Launch Site 70 70

schwit1 writes: The small sat rocket company Rocket Labs has chosen a location in New Zealand as its future launch site. Bloomberg reports: "The company didn't specify how much it was investing in the site, which is due to be completed in the fourth quarter. New Zealand, which has been used in the past by the National Aeronautical and Space Administration, is considered a prime location because rockets launched from that deep in the Southern hemisphere can reach a wide range of Earth orbits. Rocket Lab's remote site on the Kaitorete Spit in the Canterbury region also means it has less air and sea traffic, which translates into more frequent launches and economies of scale, the company said. It also will no longer compete for airspace with the U.S. government." Rocket Labs will have to actually launch something to really make the competition heat up. This announcement, however, illustrates that in the long run, the United States has some significant disadvantages as a spaceport location.

The Epidemic May be Over, But Liberia Has New Ebola Cases 11 11

Three new cases of Ebola have been reported in Liberia. Reuters reports that despite the declared end to the Ebola outbreak in that country in May, the medical community is speculating that a cluster of infectious carriers somehow survived longer than was previously believed possible, or that there is a previously unknown means of transmission. Health officials "were monitoring 175 people believed to have come into contact with the three cases, though none had yet exhibited symptoms of the disease." The report notes that "A U.S. military operation aimed at helping Liberia's government counter the outbreak has mostly withdrawn. But the Centers for Disease Control and Prevention, a U.S. health body, said it was working with local authorities to study the origin of the cases and stop the virus spreading."

First Human Colonies Should Be Among Venus' Clouds 253 253

StartsWithABang writes: When we talk about humans existing on worlds other than Earth, the first choice of a planet to do so on is usually Mars, a world that may have been extremely Earth-like for the first billion years of our Solar System or so. Perhaps, with enough ingenuity and resources, we could terraform it to be more like Earth is today. But the most Earth-like conditions in the Solar System don't occur on the surface of Mars, but rather in the high altitudes of Venus' atmosphere, some 50-65 km up. Despite its harsh conditions, this may be the best location for the first human colonies, for a myriad of good, scientific reasons. NASA proposed something similar last year and released a report on the subject.

Pew Survey Documents Gaps Between Public and Scientists 278 278

PvtVoid writes: A new Pew Research Study documents an alarming gap between public perception of scientific issues and the opinions of the scientists themselves, as measured by a poll of AAAS scientists. Even worse, the gap is partisan, with clear differences between Republicans and Democrats, and between conservatives and liberals. For example, while 98% of AAAS members agree with the statement that "Human beings and other living things have evolved over time", only 21% of conservatives agree, compared with 54% of liberals. Global warming, similarly, shows an ideological gap: 98% of AAAS scientists agreed with the statement that "the Earth is getting warmer mostly due to human activity", compared with 21% of conservatives and 54% of liberals. Encouragingly, almost everybody thinks childhood vaccines should be required (86% of AAAS members, 65% of conservatives, and 74% of liberals.) Go here for an interactive view of the data.
