MrSeb writes "Engineers at Caltech and the University of Victoria in Canada have smashed their own internet speed records, achieving a memory-to-memory transfer rate of 339 gigabits per second (53GB/s), 187Gbps (29GB/s) over a single duplex 100-gigabit connection, and a max disk-to-disk transfer speed of 96Gbps (15GB/s). At a sustained rate of 339Gbps, such a network could transfer four million gigabytes (4PB) of data per day — or around 200,000 Blu-ray movie rips. These speed records are all very impressive, but what's the point? Put simply, the scientific world deals with vasts amount of data — and that data needs to be moved around the world quickly. The most obvious example of this is CERN's Large Hadron Collider; in the past year, the high-speed academic networks connecting CERN to the outside world have transferred more than 100 petabytes of data. It is because of these networks that we can discover new particles, such as the Higgs boson. In essence, Caltech and the University of Victoria have taken it upon themselves to ride the bleeding edge of high-speed networks so that science can continue to prosper."

Lasrick writes "Fred Guterl is the executive editor of Scientific American, and in this piece he explores various threats posed by the technology that modern civilization relies on. He discusses West African and Indian monsoons, infectious diseases, and computer hacking. Here's a quote: 'Today the technologies that pose some of the biggest problems are not so much military as commercial. They come from biology, energy production, and the information sciences — and are the very technologies that have fueled our prodigious growth as a species. They are far more seductive than nuclear weapons, and more difficult to extricate ourselves from. The technologies we worry about today form the basis of our global civilization and are essential to our survival.'"
An anonymous reader writes "Lamar Smith, a global warming skeptic, will become the new chairman of the House Committee on Science, Space, and Technology. Someone who disagrees with the vast majority of scientists will be given partial jurisdiction over NASA, EPA, DOE, NSF, NOAA, and the USGS. When will candidates who are actually qualified to represent science or at a minimum show an interest in it be the representatives of science with regard to political decision-making?"
An anonymous reader writes "The BBC reports that the SABRE hybrid (part air-breathing jet, part rocket) that is intended to power the Skylon single-stage-to-orbit space plane has passed its final technical demonstration test, and is now looking for money (only £250m!) to prepare for manufacturing. If this goes ahead, travel into orbit from local airports (ideally, those close to the equator) will be possible. And quite cheaply. But might it have the same legal difficulties flying from U.S. airports as the Concorde did?"
An anonymous reader writes with this AP report: "Workers have raised the first section of a colossal arch-shaped structure that eventually will cover the exploded nuclear reactor at the Chernobyl power station. Project officials on Tuesday hailed the raising as a significant step in a complex effort to clean up the consequences of the 1986 explosion, the world's worst nuclear accident. Upon completion, the shelter will be moved on tracks over the building containing the destroyed reactor, allowing work to begin on dismantling the reactor and disposing of radioactive waste.'"
New submitter zenyu writes "IPCC's 2mm per year estimate for sea level rise at current CO2 levels has proven too optimistic. Sea levels have been rising 3.2mm per year in the last two decades. The IPCC's 50 cm — 100 cm projection for the next century may prove equally optimistic."
sighted writes "Today the robotic spacecraft Cassini returned some jaw-dropping images of the odd hexagon in the planet's north polar region. The hexagon has been seen before, but the change of season has more fully revealed the feature in visible light. Cassini also zoomed in on the churning vortex at the north pole itself. The south pole features a similar maelstrom."
An anonymous reader writes "The first large scientific study of how people respond to poor video quality on the Internet paints a picture of ever rising user expectations and the willingness to abandon ship if those expectations are not met (PDF). Some nuggets: 1) Some users are willing to wait for no more than 2 seconds for a video to start playing, with each additional second adding 6% to the abandonment rate. 2) Users with good broadband connectivity expect faster video load times and are even more impatient than ones on mobile devices. 3) Users who experience video freezing watch fewer minutes of the video than someone who does not experience freezing. If a video freezes for 1% of its total play time, 5% less of its total play time is watched, on average. 4) Users who experience failures when they try to play videos are less likely to return to the same website in the future. Big data was analyzed (260+ million minutes of video) and some cool new data analysis techniques used."
SchrodingerZ writes "Captain Scott Kelly, brother of former commander Mark Kelly, will embark on the United States' longest manned space mission, set for 2015. Kelly and Russian cosmonaut Mikhail Kornienko will spend an entire year on the orbiting International Space Station. The mission will be a first for NASA's space program, but it is far from the world record. The longest recorded time in space was the 438-day mission of Russia's Valery Polyakov, working on the Mir Space Station, 1994-1995. Kelly, a decorated Navy captain, received degrees from State University of New York Maritime College and the University of Tennessee, and was the flight engineer for space station expedition 25, and commander of expedition 26 in 2010. 'Kornienko hails from Russia's Syzran, Kuibyshev, region and has worked in the space industry since 1986.' The yearlong study on humans working in space will launch from the Baikonur Cosmodrome in Kazakhstan, spring 2015."
Covalent writes "The Large Hadron Collider, the world's largest and most powerful particle accelerator and the 'Big Bang machine' that was used to discover what appears to be the long-sought Higgs boson particle (as announced July 4), may have another surprise up its sleeve this year: The LHC looks to have produced a new type of matter, according to a new analysis of particle collision data by scientists at MIT and Rice University. The new type of matter, which has yet to be verified, is theorized to be one of two possible forms: Either 'color-glass condensate' — a flattened nucleus transformed into a 'wall' of gluons, which are smaller binding subatomic particles, or it could be 'quark-gluon plasma,' a dense, soup or liquid-like collection of individual particles."
astroengine writes "NASA has begun surveying scientists on what they would like to do with two Hubble-class space telescopes donated to the civilian space agency by its secretive sibling, the National Reconnaissance Office — which operates the nation's spy satellites. But the gifts have some formidable strings attached, including costs to develop instruments and launch the observatories. The telescopes, though declassified, also are subject to export regulations. 'We need to retain possession and control,' NASA's astrophysics division director Paul Hertz told Discovery News. 'That doesn't preclude us from partnering (with other countries). It just sets boundaries on the nature of the partnership.' NASA also isn't allowed to use the telescopes for any Earth-observing missions. Topping the list of possible missions for the donor hardware is a remake of NASA's planned Wide-Field Infrared Survey Telescope, known as WFIRST. The mission, estimated to cost between $1.5 billion and $2 billion, is intended to answer questions about dark energy, a relatively recently discovered phenomenon that is believed to be speeding up the universe's rate of expansion."
alphadogg writes "Dr. Joseph E. Murray, the Nobel laureate who conducted the world's first successful organ transplant, died Monday at the Boston hospital where the pioneering surgery was performed. He was 93. On Dec. 23, 1954, in Operating Room 2 of the Peter Bent Brigham Hospital in Boston, Dr. Murray took the healthy kidney of Ronald Herrick and sutured it into the donor's dying identical twin, Richard. With that 5½-hour operation, Dr. Murray and his team saved a life, sparked an ethical debate that still echoes today, and opened medicine to a new frontier. Murray, who focused on plastic and reconstructive surgery for most of his career, was recognized with the Nobel Prize in Medicine in 1990."
ananyo writes "It is permanently covered by a massive cap of ice up to 27 metres thick, is six times saltier than normal sea water, and at 13 C is one of the coldest aquatic environments on Earth — yet Lake Vida in Antarctica teems with life. Scientists drilling into the lake have found abundant and diverse bacteria, including at least one new phylum (full paper (PDF)). The find increases the chances that life may exist (or have once existed) on planets such as Mars and moons such as Jupiter's Europa."
Hugh Pickens writes "Charles Q. Choi reports that hairspray could one day serve as the sign that aliens have reshaped distant worlds because one group of gases that might be key to terraforming planets are CFCs. 'Our hypothesis is that evidence of intelligent life might be evident in a planetary atmosphere,' says astrobiologist Mark Claire at the Blue Marble Space Institute of Science. CFCs are entirely artificial, with no known natural process capable of creating them in atmospheres. Detecting signs of these gases on far-off worlds with telescopes might serve as potent evidence that intelligent alien civilizations were the cause, either intentionally as part of terraforming or accidentally via industrial pollution. 'An industrialized civilization will be one that will use its planetary resources for fabrication, the soon-to-be-detectable-from-Earth atmospheric byproducts of which could be a tell-tale sign of their activity,' says astrobiologist Sanjoy Som. CFCs can be easily recognized in planetary atmospheres because their atmospheric 'fingerprint' (i.e. chemical spectra) is very different from natural elements, and are a tell-tale sign that life on the surface has advanced industrial capabilities. Using state-of-the-art computer models of atmospheric chemistry and climate, researchers plan to discover what visible signs CFCs and other artificial byproducts of alien terraforming or industry might have on exoplanet atmospheres. 'We are about a decade away of being able to measure detailed compositions of the atmospheres of extrasolar planets,' says Som."
coondoggie writes "Sandia National Laboratories physicist Willis Whitfield, 92, passed away earlier this month and left a technological legacy that continues to reverberate today: The legendary clean room. The original laminar-flow 10 x 6 clean room developed 50 years ago by Whitfield was more than 1,000 times cleaner than any cleanrooms used at the time and ultimately revolutionized microelectronics, healthcare and manufacturing development. According to Sandia, with slight modifications, it is still the clean room standard today."
An anonymous reader writes "A new experimental flu vaccine made out of messenger RNA that may work for life is now being developed. German researchers said on Sunday that the vaccine, made of the genetic material that controls the production of proteins, protected animals against influenza and, unlike traditional vaccines, it may work for life and can potentially be manufactured quickly enough to stop a pandemic (abstract)."
Hugh Pickens writes "Salvatore Iaconesi, a software engineer at La Sapienza University of Rome, writes that when he was recently diagnosed with brain cancer, his first idea was to seek other opinions. He immediately asked for his clinical records in digital format, converted the data into spreadsheets, databases, and metadata files, and published them on the web site called The Cure. 'The responses have been incredible. More than 200,000 people have visited the site and many have provided videos, poems, medical opinions, suggestions of alternative cures or lifestyles, personal stories of success or, sadly, failures — and simply the statement, "I am here." Among them were more than 90 doctors and researchers who offered information and support.' The geneticist and TED fellow Jimmy Lin has offered to sequence the genome of Iaconesi's tumor after surgery, and within one day Iaconesi heard from two different doctors who recommended similar kinds of 'awake surgery,' where the brain is monitored in real time as different parts are touched. A brain map is produced and used during a second surgery. 'We are creating a cure by uniting the contributions of surgeons, homeopaths, oncologists, Chinese doctors, nutritionists and spiritual healers. The active participation of everyone involved — both experts and ex-patients — is naturally filtering out any damaging suggestion which might be proposed,' writes Iaconesi. 'Send us videos, poems, images, audio or text that you see as relevant to a scenario in which art and creativity can help form a complete and ongoing cure. Or tell us, "I am here!" — alive and connected, ready to support a fellow human being.'"
The tough economic times have had a huge effect on scientific research and development funding. The looming "fiscal cliff" may be the last straw for many programs. "The American science programs that landed the first man on the moon, found cures for deadly diseases and bred crops that feed the world now face the possibility of becoming relics in the story of human progress. American scientific research and development stands to lose thousands of jobs and face a starvation diet of reduced funding if politicians fail to compromise and halt the United States' march towards the fiscal cliff's sequestration of federal funds."
A study has found that a decreased pH level in the antarctic is damaging the shells of native wildlife. "Marine snails in seas around Antarctica are being affected by ocean acidification, scientists have found. An international team of researchers found that the snails' shells are being corroded. Experts says the findings are significant for predicting the future impact of ocean acidification on marine life. The results of the study are published in the journal Nature Geoscience (abstract). The marine snails, called "pteropods", are an important link in the oceanic food chain as well as a good indicator of ecosystem health. 'They are a major grazer of phytoplankton and... a key prey item of a number of higher predators - larger plankton, fish, seabirds, whales,' said Dr Geraint Tarling, Head of Ocean Ecosystems at the British Antarctic Survey and co-author of the report."
SternisheFan writes "The structure of the universe and the laws that govern its growth may be more similar than previously thought to the structure and growth of the human brain and other complex networks, such as the Internet or a social network of trust relationships between people, according to a new study. 'By no means do we claim that the universe is a global brain or a computer,' said Dmitri Krioukov, co-author of the paper, published by the Cooperative Association for Internet Data Analysis (CAIDA), based at the San Diego Supercomputer Center (SDSC) at the University of California, San Diego.'But the discovered equivalence between the growth of the universe and complex networks strongly suggests that unexpectedly similar laws govern the dynamics of these very different complex systems,' Krioukov noted."
