Radioactive Tool Goes Missing In Texas 163

Hugh Pickens writes "Oil-field service companies lower radioactive units into wells to let workers identify places to break apart rock for a drilling process known as hydraulic fracturing, or fracking, which frees oil and natural gas. Now Bloomberg reports that Halliburton workers have discovered that a lock on the container used to transport one such device has gone missing, along with the unit, after employees drove a truck from a site near Peco to a well south of Odessa and while the loss of radioactive rods occurs from time to time, it has been years since a device with americium-241/beryllium, the material in Halliburton's device, was misplaced in Texas. NRC spokeswoman Maureen Conley says the material would have to be in someone's physical possession for several hours for it to be considered harmful as teams comb the route between the two wellsites searching for the seven-inch tube, which is clearly marked with the words 'DANGER RADIOACTIVE' as well as a radiation warning symbol, "Halliburton strongly cautions members of the public that if they locate this source, they should not touch or handle it, stay a minimum of 25 feet away," and contact local law enforcement or the company's emergency hotline if they find the cylinder, says the company which is also offering a reward for information about the tube's whereabouts."

How the Critics of the Apollo Program Were Proven Wrong 421

MarkWhittington writes "A recent story in The Atlantic reminds us that the Apollo program, so fondly remembered in the 21st Century, was opposed by a great many people while it was ongoing, on the theory that the money spent going to the moon would have been better spent on poverty programs. The problem with this view was that spending for Lyndon Johnson's Great Society dwarfed the Apollo program, that the programs in the Great Society largely failed to address poverty and other social ills, and that the Apollo program actually had a stimulative effect on the economy that fostered economic growth and created jobs by driving the development of technology,"

Shuttle Endeavour Embarking to Los Angeles Museum 56

Endeavour will be the second of NASA's space shuttles to leave the Kennedy Space Center. The ship will piggyback on top of a specially modified 747 and head to a Los Angeles museum this week. From the article: "Endeavour's lifespan was relatively short by shuttle standards - 25 missions over 20 years, totaling 299 days in space. But those flights ran the gamut of orbital odysseys, including the sheer moxie of its May 1992 debut when three astronauts made an impromptu and unprecedented spacewalk to rescue a stranded Intelsat communications satellite."

50 Years of Research and Still No Microwave Weapons 154

DevotedSkeptic writes in with a story about the lack of usable microwave technology to come from 50 years of military research. "For some Pentagon officials, the demonstration in October 2007 must have seemed like a dream come true — an opportunity to blast reporters with a beam of energy that causes searing pain. The event in Quantico, Virginia, was to be a rare public showing for the US Air Force's Active Denial System: a prototype non-lethal crowd-control weapon that emits a beam of microwaves at 95 gigahertz. Radiation at that frequency penetrates less than half a millimetre into the skin, so the beam was supposed to deliver an intense burning sensation to anyone in its path, forcing them to move away, but without, in theory, causing permanent damage. However, the day of the test was cold and rainy. The water droplets in the air did what moisture always does: they absorbed the microwaves. And when some of the reporters volunteered to expose themselves to the attenuated beam, they found that on such a raw day, the warmth was very pleasant. The story is much the same in other areas of HPM weapons development, which began as an East–West technology race nearly 50 years ago. In the United States, where spending on electromagnetic weapons is down from cold-war levels, but remains at some US$47 million per year, progress is elusive. 'There's lots of smoke and mirrors,' says Peter Zimmerman, an emeritus nuclear physicist at King's College London and former chief scientist of the US Arms Control and Disarmament Agency in Washington DC. Although future research may yield scientific progress, he adds, 'I cannot see they will build a useful, deployable weapon.'"

NASA To Face $1.3 Billion Cut Next Year Under Sequestration 242

littlesparkvt writes "A budget forecast that was released on Friday shows that the defense department isn't the only department getting hammered: NASA is as well, if the automatic budget cuts happen. According to Nature magazine, NASA will lose '$417 million from its science budget, $346 for space operations, $309 for exploration, $246 for cross agency support, among other cuts.'"

Detailed Images Show Intra-Molecular Bonds 53

Techmeology writes "A team from IBM in Zurich has published images of molecules that are detailed enough to show the lengths of atomic bonds. 'The IBM team's innovation to create the first single molecule picture, of a molecule called pentacene, was to use the tip to pick up a single, small molecule made up of a carbon and an oxygen atom. This carbon monoxide molecule effectively acts as a record needle, probing with unprecedented accuracy the very surfaces of atoms. It is difficult to overstate what precision measurements these are. The experiments must be isolated from any kind of vibration coming from within the laboratory or even its surroundings. They are carried out at a scale so small that room temperature induces wigglings of the AFM's constituent molecules that would blur the images, so the apparatus is kept at a cool -268C.' This allows an analysis of imperfections in the molecular structure (abstract). The team plans to use the method to examine molecules of graphene."

Ultrasound Waves For Transdermal Drug Delivery 32

An anonymous reader writes with news of research from MIT, where engineers have found a better way to use ultrasound waves to boost the permeability of skin for the delivery of drugs. "Ultrasound — sound waves with frequencies greater than the upper limit of human hearing — can increase skin permeability by lightly wearing away the top layer of the skin, an effect that is transient and pain-free. ... When ultrasound waves travel through a fluid, they create tiny bubbles that move chaotically. Once the bubbles reach a certain size, they become unstable and implode. Surrounding fluid rushes into the empty space, generating high-speed 'microjets' of fluid that create microscopic abrasions on the skin. In this case, the fluid could be water or a liquid containing the drug to be delivered. In recent years, researchers working to enhance transdermal drug delivery have focused on low-frequency ultrasound, because the high-frequency waves don’t have enough energy to make the bubbles pop. However, those systems usually produce abrasions in scattered, random spots across the treated area. In the new study (abstract), the MIT team found that combining high and low frequencies offers better results. The high-frequency ultrasound waves generate additional bubbles, which are popped by the low-frequency waves."

Mammoth Tooth Found In Downtown San Francisco 66

DevotedSkeptic writes with this excerpt pulled from the San Francisco Chronicle:"A seemingly ordinary day at the Transbay Transit Center construction site became a mammoth day of discovery Monday when a mild-mannered crane operator reached deep into the earth and pulled out a tooth. This was no ordinary tooth. The 10-inch-long brown, black and beige chomper, broken in two and missing a chunk, once belonged to a woolly mammoth, an elephantine creature that roamed the grassy valley that's now San Francisco Bay 10 to 15 thousand years ago in the Pleistocene epoch."

Monkeys Made Smarter With Prosthetic Device 102

An anonymous reader writes "Scientists have successfully restored and, in some cases, enhanced decision-making ability in brain-damaged monkeys on cocaine by connecting a prosthetic device to their brains. 'In the study, the scientists trained five monkeys to match multiple images on a computer screen until they were correct 70 to 75 percent of the time. First, an image appeared on the screen, which the animals were trained to select using a hand-controlled cursor. The screen then went blank for up to two minutes, followed by the reappearance of two to eight images, including the initial one, on the same screen. When the monkeys correctly chose the image they were shown first, the electronic prosthetic device recorded the pattern of neural pulses associated with their decision by employing a multi-input multi-output nonlinear (MIMO) mathematical model, developed by researchers at the University of Southern California. In the next phase of the study, a drug known to disrupt cognitive activity, cocaine, was administered to the animals to simulate brain injury. When the animals repeated the image-selection task, their decision-making ability decreased 13 percent from normal. However, during these "drug sessions," the MIMO prosthesis detected when the animals were likely to choose the wrong image and played back the previously recorded "correct" neural patterns for the task. According to the study findings, the MIMO device was exceedingly effective in restoring the cocaine-impaired decision-making ability to an improved level of 10 percent above normal, even when the drug was still present and active.'"

Rewiring the Autistic Brain 139

sciencehabit writes "Signs of autism — such as impaired social skills and repetitive, ritualistic movements — usually begin to appear when a child is about 18 months old. Autism is thought to result from miswired connections in the developing brain, and many experts believe that therapies must begin during a 'critical window,' before the faulty circuits become fixed in place. But a new study (abstract) shows that at least one malfunctioning circuit can be repaired after that window closes, holding out hope that in some forms of autism, abnormal circuits in the brain can be corrected even after their development is complete."

Smooth, High Definition Video of Curiosity's Landing On Mars 78

_0x783czar writes "Filmmaker Brad Canning has released a hi-def video of Curiosity's landing. This video was captured in low res, and then extrapolated and re-rendered by Canning to produce some of the most stunning imagery ever captured on an alien world. It took Canning over a month to complete the process. He used motion tracking to add sound effects which in turn give you the sensation of the ride of your life."

Elon Musk, an Industrialist For the 21st Century 89

pacopico writes "Elon Musk has just come off a pretty amazing run. SpaceX docked with the ISS. Tesla has started selling its all-electric luxury sedan, and SolarCity just filed to go public. Bloomberg Businessweek spent a few days with Musk and got a look inside his insane factories in Silicon Valley and Los Angeles. It's like Willy Wonka time for geeks. Among the other proclamations in the story is Musk saying that he intends to die on Mars. 'Just not on impact.' Musk then goes on to describe a fifth mode of transportation he's calling the Hyperloop."

Astronomers Fix the Astronomical Unit 182

gbrumfiel writes "The Astronomical Unit (AU) is known to most as the distance between the Earth and the Sun. In fact, the official definition was a much more complex mathematical calculation involving angular measurements, hypothetical bodies, and the Sun's mass. That old definition created problems: due to general relativity, the length of the AU changed depending on an observer's position in the solar system. And the mass of the Sun changes over time, so the AU was changing as well. At the International Astronomical Union's latest meeting, astronomers unanimously voted on a new simplified definition: exactly 149,597,870,700 meters. Nobody need panic, the earth's distance from the sun remains just as it was, regardless of whether it's in AUs, meters, or smoots."

Curiosity Gearing Up for Drive to Next Study Location 73

Curiosity has spent most of the past 5 weeks running instrument and system checks, but on Friday that is all scheduled to change. The plan is to "drive, drive, drive" until a suitable rock for the rover's first robotic "hands-on" analysis is found, says mission manager Jennifer Trosper. The rover will head to a location about 1,300 feet away labeled "Glenelg," where three different types of rock intersect.

Unusual Discovery of New African Monkey Species 71

rhettb writes "In a remote and largely unexplored rainforest of the Democratic Republic of the Congo, researchers have made an astounding discovery: a new monkey species. The new primate, which is name the lesula and described in a paper in the journal PLoS ONE, was first noticed by scientist and explorer John Hart in 2007. The discovery of a new primate species is rare nowadays. In fact, the lesula is only the second newly discovered monkey in Africa in the past 28 years."

Ancient Egyptian Tech May Be Key To Printing 3D Ceramics 138

Zothecula writes "We like to think of technology as always being forward looking. It's supposed to be about nanoparticles and the Cloud, not steam engines and the telephone exchange. But every now and again the past reaches out, taps the 21st century on the shoulder and says, 'Have a look at this.' That's what happened to Professor Stephen Hoskins, Director of the University of West England, Bristol's Centre for Fine Print Research. He is currently working on a way of printing 3D ceramics that are self-glazing, thanks to a 7,000-year old technology from ancient Egypt."

Video George Albercook Teaches Kids About Space with High-Altitude Balloons (Video) Screenshot-sm 21

George Albercook says he got carried away talking with some third and fourth graders about space and asked them, "Would you like to go?" Except, of course, he couldn't send them beyond the atmosphere in person, so as a consolation he worked with them to send up a balloon that could carry experiments high enough that the sky is black 24 hours a day and the Earth's curvature is easy to see. This interview with George was at the 2012 Ann Arbor Mini Maker Faire. Click on the link just below, if you'd like to read the transcript.

Canadian Scientists Bind High-Temp Superconductor Components With Scotch Tape 97

A user writes "Scotch tape really can fix anything according to a new study where it was used to induce super conductivity by taping two pieces of material together. A "proximity effect" occurs when a superconducting material is able to induce superconducting behavior in a second material — a semiconductor that does not typically enjoy superconductivity." All that and X-rays, too. Related: An anonymous reader writes "Scientist at University of Leipzig in Germany claim to have measured room-temperature superconducting in specially treated graphite grains. The measurements were reproduced independently before the announcement was made. More tests need to be done to verify the extent of superconductivity and whether the effect can be extended and scaled to be practical."

World's First Color Moving Pictures Discovered 105

BoxRec writes "The BBC is reporting newly-discovered films made by pioneer Edward Raymond Turner from London, who patented his colour process on 22 March 1899." When Turner invented his process, though, existing projection systems weren't up to it; to see the discovered footage, British archivists digitized the film for computer playback. When you're used to old films being both black and white and jerky, it's amazing to see it in color and (relatively) smooth.

Scientists Themselves Play Large Role In Bad Reporting 114

Hugh Pickens writes "A lot of science reporting is sensationalized nonsense, but are journalists, as a whole, really that bad at their jobs? Christie Wilcox reports that a team of French scientists have examined the language used in press releases for medical studies and found it was the scientists and their press offices that were largely to blame. As expected, they found that the media's portrayal of results was often sensationalistic. More than half of the news items they examined contained spin. But, while the researchers found a lot of over-reporting, they concluded that most of it was 'probably related to the presence of ''spin'' in conclusions of the scientific article's abstract.' It turns out that 47% of the press releases contained spin. Even more importantly, of the studies they examined, 40% of the study abstracts or conclusions did, too. When the study itself didn't contain spin to begin with, only 17% of the news items were sensationalistic, and of those, 3/4 got their hype from the press release. 'In the journal articles themselves, they found that authors spun their own results a variety of ways,' writes Wilcox. 'Most didn't acknowledge that their results were not significant or chose to focus on smaller, significant findings instead of overall non-significant ones in their abstracts and conclusions, though some contained outright inappropriate interpretations of their data.'"
