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.'"

Star Trek Tech That Exists Today 207

Esther Schindler writes "When Star Trek hit the air waves, talking computers were just a pipe dream. While teleportation remains elusive, several once-fictional technologies are changing the way people live and work. Here are some ways in which we're approaching the gizmos that Star Trek demonstrated. Speech recognition? Check. Holodeck? Sort of. Replicator? Workin' on it."

Stem Cells Turn Hearing Back On 101

puddingebola sends this excerpt from an article at ScienceNow: "Scientists have enabled deaf gerbils to hear again — with the help of transplanted cells that develop into nerves that can transmit auditory information from the ears to the brain. The advance, reported today in Nature, could be the basis for a therapy to treat various kinds of hearing loss. ... Rivolta and his colleagues knew that during embryonic development, a handful of proteins, including fibroblast growth factor (FGF) 3 and 10, are required for ears to form. So they exposed human embryonic stem cells to FGF3 and FGF10. Multiple types of cells formed, including precursor inner-ear hair cells, but they were also able to identify and isolate the cells beginning to differentiate into the desired spiral ganglion neurons. Then, they implanted the neuron precursor cells into the ears of gerbils with damaged ear neurons and followed the animals for 10 weeks. The function of the neurons was restored.'"

Turning Data Science Into a Spectator 'Sport' 19

vu1986 writes "Kaggle has a 'predictive-modeling competition platform that makes public the competitors in invite-only private competitions. Think of it like watching a major tournament in golf or tennis, where you can watch the best in the world shoot it out to see whose algorithms are king. Kaggle's tagline is "We're making data science a sport." Maybe now it can make data science a spectator sport.'"

Confusion and Criticism Over ENCODE's Claims 34

As_I_Please writes "In response to the previous report of the ENCODE project discovering 'biochemical functions for 80 percent of the genome,' many scientists have questioned what was meant by 'function.' Ars Technica Science Editor John Timmer wrote an article calling ENCODE's definition of functionality 'broad to the point of being meaningless. At worst, it was actively misleading.' Nature magazine also has a followup discussing the ambiguity surrounding the 80% figure and claims about junk DNA."

Around 200,000 Tons of Deep Water Horizon Oil and Gas Consumed By Bacteria 170

SchrodingerZ writes "The University of Rochester and Texas A&M University have determined that in the five months following the Deepwater Horizon Disaster in the Gulf of Mexico, bacteria have consumed over 200,000 tons of oil and natural gas. The researched was published in the journal Environmental Science and Technology (abstract). 'A significant amount of the oil and gas that was released was retained within the ocean water more than one-half mile below the sea surface. It appears that the hydrocarbon-eating bacteria did a good job of removing the majority of the material that was retained in these layers," said co-author John Kessler of the University of Rochester.' The paper debuts for the first time 'the rate at which the bacteria ate the oil and gas changed as this disaster progressed, information that is fundamental to understanding both this spill and predicting the behavior of future spills.' It was also noted that the oil and gas consumption rate was correlated with the addition of dispersants at the wellhead (video). Still, an estimated 40% of the oil and natural gas from the spill remains in the Gulf today."

GAO Slams DHS Over BioWatch Biological Defense System 88

Mansing writes "Citizens need to evaluate if they are indeed safer for all the 'security precautions' put into place. 'The U.S. Department of Homeland Security has rushed to acquire a new, multibillion-dollar version of the BioWatch system for detecting biological attacks without establishing whether it was needed or would work, according to a new report by a nonpartisan investigative arm of Congress. ... The existing system's repeated false alarms have triggered tense, high-stakes deliberations over whether to order mass evacuations, distribute emergency medicines or shut down major venues.' Is this just more money funneled to U.S. companies, or is this really keeping the U.S. safer? Are the same types of 'security precautions' being instituted in Spain and the UK? Or is this preying on fear a uniquely U.S. phenomenon?"

Exposing the Machinery of the Resistome 23

aarondubrow writes "2011 Nobel Prize Winner, Bruce Beutler, is using the Ranger supercomputer at The University of Texas at Austin for an ambitious new project to discover all of the genes involved in the mammalian immune response – the so-called 'resistome.' Over several years, Beutler's lab will sequence the protein coding portions of genes in 8,000 mice to detect the impact of mutations on immunity. This means scanning, enriching and sequencing 500 billion base pairs every week. The project represents a 'Big Data' problem of the highest order."

Synthetic Materials Set New World Record For Greatest Amount of Surface Area 96

Zothecula writes "Researchers at Northwestern University, Illinois, have broken a world record in the creation of two synthetic materials, named NU-109 and NU-110, which have the greatest amount of surface areas of any material to date (abstract). To put this into perspective: if one were able to take a crystal of NU-110 the size of a grain of salt, and somehow unfold it, the surface area would cover a desktop. Additionally, the internal surface area of just one gram of the new material would cover one-and-a-half football fields."

How Does the Tiny Waterbear Survive In Outer Space? 119

DevotedSkeptic sends this excerpt from SmithsonianMag: "The humble tardigrade, also known as a 'waterbear' or 'moss piglet,' is an aquatic eight-legged animal that typically grows no longer than one millimeter in length. Most tardigrades (there are more than 1,000 identified species) have a fairly humdrum existence, living out their days on a moist piece of moss or in the sediment at the bottom of a lake and feeding on bacteria or plant life. In 2007, a group of European researchers pushed the resilience of this extraordinary animal even further, exposing a sample of dehydrated tardigrades to the vacuum and solar radiation of outer space for 10 full days. When the specimens were returned to earth and rehydrated, 68 percent of those that were shielded from the radiation survived, and even a handful of those with no radiation protection came back to life and produced viable offspring. How do the little tardigrades survive such a harsh environment? Although amateur tardigrade enthusiast Mike Shaw recently made waves by postulating that the animals may be equipped to survive in outer space because they originally came from other planets, scientists are certain that the creatures developed their uncommon toughness here on earth."

Scientists Built the 'Hubble Telescope For the Ocean' Using the Cloud 36

New submitter stacey7165 writes "VMware shared the application architecture story of how they worked with the Ocean Observatory Initiative to build a 'Hubble Telescope' of the ocean. It's comprised of a massive network of global, regional, and coastal sensors that send information to a common framework called the Common Operating Infrastructure (COI). The COI resides in a hybrid cloud powered by VMware and Amazon. To cope with a total of 49 classes and over 700 instruments deployed off of 6 coastlines, and a variety of consumption use cases, the Ocean Observatory Initiative built out the system using a variety of sub-systems loosely coupled through a messaging system powered by RabbitMQ called an 'Exchange.' Organized into a system where message clients pubsub from 'Exchange Points' and 'Exchange Spaces', the system is easier to maintain, extend, and scale. According to the OOI's documentation on release 1, the Integrated Observatory Network uses AMQP 0.9.1 and RabbitMQ-Server v. 2.3.1 on CentOS 5.5."

Amateur Astronomers Spot Jovian Blast 86

RocketAcademy writes "Spaceweather.com reports an explosion on Jupiter, which was detected by two amateur astronomers. According to Spaceweather.com, the event occurred at 11:35 Universal Time on September 10. Dan Peterson of Racine, Wisconsin, observing through a 12-inch Meade telescope, observed a white flash lasting for 1.5-2 seconds. George Hall of Dallas, Texas was capturing a video of Jupiter at the time, which also captured the event. It's believed that the explosion was due to a comet or small asteroid collision. Similar events were observed in the past, in June and August 2010."
