Earth 8

The eruption of the Bardarbunga volcano in central Iceland, which appeared a strong possibility after a series of earthquakes, is currently underway, beneath the ice of the Dyngjujokull glacier. The BBC reports that Iceland has raised its air travel alert to red, its higest level, but that for now all of Iceland's airports remain open. CNN notes that "the underground activity did not immediately result in changes to volcanic activity on the surface ... Because of a pressure from the glacier cap it is uncertain whether the eruption will stay sub-glacial or not, Iceland 2 TV said."

Oregon Sues Oracle For "Abysmal" Healthcare Website

Oracle 53

SpzToid (869795) writes The state of Oregon sued Oracle America Inc. and six of its top executives Friday, accusing the software giant of fraud for failing to deliver a working website for the Affordable Care Act program. The 126-page lawsuit claims Oracle has committed fraud, lies, and "a pattern of activity that has cost the State and Cover Oregon hundreds of millions of dollars". "Not only were Oracle's claims lies, Oracle's work was abysmal", the lawsuit said. Oregon paid Oracle about $240.3 million for a system that never worked, the suit said. "Today's lawsuit clearly explains how egregiously Oracle has disserved Oregonians and our state agencies", said Oregon Atty. Gen. Ellen Rosenblum in a written statement. "Over the course of our investigation, it became abundantly clear that Oracle repeatedly lied and defrauded the state. Through this legal action, we intend to make our state whole and make sure taxpayers aren't left holding the bag."

Oregon's suit, alleges that Oracle, the largest tech contractor working on the website, made falsely convinced officials to buy "hundreds of millions of dollars of Oracle products and services that failed to perform as promised." It is seeking $200 million in damages. Oracle issued a statement saying the suit "is a desperate attempt to deflect blame from Cover Oregon and the governor for their failures to manage a complex IT project. The complaint is a fictional account of the Oregon Healthcare Project."

It's Dumb To Tell Kids They're Smart

theodp writes Over at Khan Academy, Salman Khan explains Why I'm Cautious About Telling My Son He's Smart. "Recently," writes Khan, "I put into practice research I had been reading about for the past few years: I decided to praise my son not when he succeeded at things he was already good at, but when he persevered with things that he found difficult. I stressed to him that by struggling, your brain grows. Between the deep body of research on the field of learning mindsets and this personal experience with my son, I am more convinced than ever that mindsets toward learning could matter more than anything else we teach." According to Dr. Carol Dweck, who Khan cites, the secret to raising smart kids is not telling kids that they are. A focus on effort — not on intelligence or ability — says Dweck, is key to success in school and in life.

2 Galileo Satellites Launched To Wrong Orbit

As reported by the BBC, two satellites meant to form part of the EU's Galileo global positioning network have been launched into a wrong, lower orbit, and it is unclear whether they can be salvaged. NASASpaceFlight.com has a more detailed account of the launch, which says [D]espite the Arianespace webcast noting no issue with the launch, it was later admitted the satellites were lofted into the wrong orbit. “Following the announcement made by Arianespace on the anomalies of the orbit injection of the Galileo satellites, the teams of industries and agencies involved in the early operations of the satellites are investigating the potential implications on the mission,” noted a short statement, many hours after the event. It is unlikely the satellites can be eased into their correct orbit, even with a large extension to their transit time. However, ESA are not classing the satellites as lost at this time. “Both satellites have been acquired and are safely controlled and operated from ESOC, ESA’s Operations Centre in Darmstadt, Germany,” the Agency added. Over the course of the next "year or so," an additional 24 satellites are slated to complete the Galileo constellation, to be launched by a mixed slate of Ariane and Soyuz rockets.

A Better Way To Make Mind-Controlled Prosthetic Limbs

Biotech 26

the_newsbeagle writes: To make a brain-machine interface, you need a way to capture neurons' electric signals. The most precise and most invasive way uses implants that are stuck in the gray matter. The least precise and least invasive way uses EEG sensors stuck to the scalp. But researchers at Johns Hopkins University say there's a third way that gets the best of both worlds, which is not too invasive and fairly precise. They use ECoG systems, in which a mesh of electrodes is placed under the skull, draped over the surface of the cortex.

They're testing their systems on epilepsy patients, who have these ECoG systems inserted anyway while they're waiting for surgery (the electrodes record the source of their seizures). The researchers are capturing these patients' movement commands from their brains, and using them to control robotic limbs. Someday such a system could be used by amputees to control their prosthetic limbs.

A Movie of Triton Made From Voyager 2's Fly-by 25 Years Ago

schwit1 writes: Using restored images taken by Voyager 2 when it flew past Neptune's moon Triton 25 years ago, scientists have produced a new map and flyby movie of the moon. "The new Triton map has a resolution of 1,970 feet (600 meters) per pixel. The colors have been enhanced to bring out contrast but are a close approximation to Triton's natural colors. Voyager's "eyes" saw in colors slightly different from human eyes, and this map was produced using orange, green and blue filter images. ... Although Triton is a moon of a planet and Pluto is a dwarf planet, Triton serves as a preview of sorts for the upcoming Pluto encounter. Although both bodies originated in the outer solar system, Triton was captured by Neptune and has undergone a radically different thermal history than Pluto. Tidal heating has likely melted the interior of Triton, producing the volcanoes, fractures and other geological features that Voyager saw on that bitterly cold, icy surface. Pluto is unlikely to be a copy of Triton, but some of the same types of features may be present." Dr. Paul Schenk provides provides further information on his blog, and the movie can be viewed here.

Jason Koebler writes: In order to get inside China's notorious internet filter, Harvard researcher Gary King created his own fake social network to gain access to the programs used to censor content, so he could reverse-engineer the system. "From inside China, we created our own social media website, purchased a URL, rented server space, contracted with one of the most popular software platforms in China used to create these sites, submitted, automatically reviewed, posted, and censored our own submissions," King wrote in a study published in Science. "We had complete access to the software; we were even able to get their recommendations on how to conduct censorship on our own site in compliance with government standards."

Scientists Confirm Life Under Antarctic Ice

Science 46

MikeChino writes A new paper by a group of researchers from Montana State University confirms that life can survive under antarctic ice. Researchers led by John Priscu drilled down into the West Antarctic Ice Sheet and pulled up organisms called Archaea. These organisms survive by converting methane into energy, enabling them to survive where there is no wind or sunlight, buried deep under the ice.

The Star That Exploded At the Dawn of Time

Space 55

sciencehabit writes To probe the dawn of time, astronomers usually peer far away; but now they've made a notable discovery close to home. An ancient star a mere thousand light-years from Earth bears chemical elements that may have been forged by the death of a star that was both extremely massive and one of the first to arise after the big bang. If confirmed, the finding means that some of the universe's first stars were so massive they died in exceptionally violent explosions that altered the growth of early galaxies.

Cause of Global Warming 'Hiatus' Found Deep In the Atlantic

Earth 377

vinces99 writes with news about a study that may account for a slowdown in air temperature rises. Following rapid warming in the late 20th century, this century has so far seen surprisingly little increase in the average temperature at the Earth's surface. More than a dozen theories have now been proposed for the so-called global warming hiatus, ranging from air pollution to volcanoes to sunspots. New research from the University of Washington shows the heat absent from the surface is plunging deep in the north and south Atlantic Ocean, and is part of a naturally occurring cycle. The study is published in Science. Subsurface ocean warming explains why global average air temperatures have flatlined since 1999, despite greenhouse gases trapping more solar heat at the Earth's surface. "Every week there's a new explanation of the hiatus," said corresponding author Ka-Kit Tung, a UW professor of applied mathematics and adjunct faculty member in atmospheric sciences. "Many of the earlier papers had necessarily focused on symptoms at the surface of the Earth, where we see many different and related phenomena. We looked at observations in the ocean to try to find the underlying cause." What they found is that a slow-moving current in the Atlantic, which carries heat between the two poles, sped up earlier this century to draw heat down almost a mile (1,500 meters). Most previous studies focused on shorter-term variability or particles that could block incoming sunlight, but they could not explain the massive amount of heat missing for more than a decade.

Scientists Developing Remote-Control Cyborg Moths

Zothecula writes We've been hearing a lot about the development of tiny flying sensor-equipped robots, that could be sent into areas such as disaster sites to seek out survivors or survey the damage. However, why go to the trouble of designing those robots from scratch, when there are already ready-made insects that are about the right size? That's the thinking behind research being conducted at North Carolina State University, which is aimed at converting moths into "biobots".

NASA's Space Launch System Searches For a Mission

Space 53

schwit1 writes: Managers of NASA's Space Launch System (SLS) are searching for a mission that they can propose and convince Congress to fund. "Once SLS is into the 2020s, the launch rate should see the rocket launching at least once per year, ramping up to a projected three times per year for the eventual Mars missions. However, the latter won’t be until the 2030s. With no missions manifested past the EM-2 flight, the undesirable question of just how 'slow' a launch rate would be viable for SLS and her workforce has now been asked." Meanwhile, two more Russian rocket engines were delivered yesterday, the first time that's happened since a Russian official threatened to cut off the supply. Another shipment of three engines is expected later this year. In Europe, Arianespace and the European Space Agency signed a contract today for the Ariane 5 rocket to launch 12 more of Europe’s Galileo GPS satellites on three launches. This situation really reminds me of the U.S. launch market in the 1990s, when Boeing and Lockheed Martin decided that, rather than compete with Russia and ESA for the launch market, they instead decided to rely entirely on U.S. government contracts, since those contracts didn’t really demand that they reduce their costs significantly to compete.

New Research Suggests Cancer May Be an Intrinsic Property of Cells

Medicine 180

cranky_chemist sends this report from NPR: "Cancer simply may be here to stay. Researchers at Kiel University, the Catholic University of Croatia and other institutions discovered that hydra — tiny, coral-like polyps that emerged hundreds of millions of years ago — form tumors similar to those found in humans. Which suggests that our cells' ability to develop cancer is "an intrinsic property" that has evolved at least since then — way, way, way before we rallied our forces to try to tackle it, said Thomas Bosch, an evolutionary biologist at Kiel University who led the study, published in Nature Communications in June (abstract) To get ahead of cancer, he said, "you have to interfere with fundamental pathways. It's a web of interactions," he said. "It's very difficult to do." That's why cancer "will probably never be completely eradicated."

Metamaterial Superconductor Hints At New Era of High Temperature Superconductors

Soulskill posted 2 days ago | from the resistance-is-futile-at-extremely-low-temperatures dept.

Science 38

KentuckyFC writes: Superconductors allow current to flow with zero resistance when cooled below some critical temperature. They are the crucial ingredients in everything from high-power magnets and MRI machines to highly sensitive magnetometers and magnetic levitation devices. But one big problem is that superconductors work only at very low temperatures — the highest is around 150 kelvin (-120 degrees centigrade). So scientists would dearly love to find ways of raising this critical temperature. Now a group of physicists say they've found a promising approach: to build metamaterial superconductors that steer electrons in the same way as other metamaterials steer light to create invisibility cloaks. The inspiration for the work comes from the observation that some high temperature superconductors consist of repeated layers of conducting and dielectric structures. So the team mixed tin — a superconductor at 3.7 kelvin — with the dielectric barium titanate and found that it raised the critical temperature by 0.15 kelvin. That's the first demonstration that superconductors can be thought of as metamaterials. With this proof of principle under their belts, the next step is to look for bigger gains at higher temperatures.

Experimental Drug Stops Ebola-like Infection

Medicine 51

sciencehabit writes: An experimental treatment against an Ebola-related virus can protect monkeys even when given up to 3 days after infection, the point at which they show the first signs of disease. The virus, known as Marburg, causes severe hemorrhagic fever—vomiting, diarrhea, and internal bleeding. In one outbreak, it killed 90% of people it infected. There are no proven treatments or vaccines against it. The new results raise hopes that the treatment might be useful for human patients even if they don't receive it until well after infection. The company that makes the compound, Tekmira, based in Burnaby, Canada, has started a human safety trial of a related drug to treat Ebola virus disease, and researchers hope that it, too, might offer protection even after a patient has started to feel ill. In other Ebola news, the two American aid workers who were infected with the virus while in Liberia have now recovered and been released from the hospital.

The First Particle Physics Evidence of Physics Beyond the Standard Model?

StartsWithABang writes It's the holy grail of modern particle physics: discovering the first smoking-gun, direct evidence for physics beyond the Standard Model. Sure, there are unanswered questions and unsolved puzzles, ranging from dark matter to the hierarchy problem to the strong-CP problem, but there's no experimental result clubbing us over the head that can't be explained with standard particle physics. That is, the physics of the Standard Model in the framework of quantum field theory. Or is there? Take a look at the evidence from the muon's magnetic moment, and see what might be the future of physics.

The Almighty Buck 25

aarondubrow writes The National Science Foundation today announced two $10 million projects to create cloud computing testbeds — to be called "Chameleon" and "CloudLab" — that will enable the academic research community to experiment with novel cloud architectures and pursue new, architecturally-enabled applications of cloud computing. While most of the original concepts for cloud computing came from the academic research community, as clouds grew in popularity, industry drove much of the design of their architecture. Today's awards complement industry's efforts and enable academic researchers to advance cloud computing architectures that can support a new generation of innovative applications, including real-time and safety-critical applications like those used in medical devices, power grids, and transportation systems.

Study: Seals Infected Early Americans With Tuberculosis

mdsolar writes that a study suggests that tuberculosis first appeared in the New World less than 6,000 years ago and it was brought here by seals. After a remarkable analysis of bacterial DNA from 1,000-year-old mummies, scientists have proposed a new hypothesis for how tuberculosis arose and spread around the world. The disease originated less than 6,000 years ago in Africa, they say, and took a surprising route to reach the New World: it was carried across the Atlantic by seals. The new study, published Wednesday in the journal Nature, has already provoked strong reactions from other scientists. "This is a landmark paper that challenges our previous ideas about the origins of tuberculosis," said Terry Brown, a professor of biomolecular archaeology at the University of Manchester. "At the moment, I'm still in the astonished stage over this."
