Japan's Radiation Disaster Toll: None Dead, None Sick 319

An anonymous reader writes "This article discusses a recently-released U.N. Scientific Committee report which examined the health effects of the accident at the Fukushima nuclear plant. Their conclusion: 'Radiation exposure following the nuclear accident at Fukushima-Daiichi did not cause any immediate health effects. It is unlikely to be able to attribute any health effects in the future among the general public and the vast majority of workers. ... No radiation-related deaths or acute effects have been observed among nearly 25,000 workers involved at the accident site. Given the small number of highly exposed workers, it is unlikely that excess cases of thyroid cancer due to radiation exposure would be detectable.' The article even sums up the exposure levels for the workers who were closest to the reactor: 'Of 167 exposed to more than the industry's recommended five-year limit of 100 mSv (a CT scan exposes patients to up to 10 mSv), 23 recorded 150-200 mSv, three 200-250 mSv and six up to 678 mSv, still short of the 1000 mSv single dosage that causes radiation sickness, or the accumulated exposure estimated to cause a fatal cancer years later in 5 per cent of people.' The report also highlights the minute effect it's had on the environment: 'The exposures on both marine and terrestrial non-human biota were too low for observable acute effects.'"

Temporal Cloak Erases Data From History 102

ananyo writes "Electrical engineers have used lasers to create a cloak that can hide communications in a 'time hole', so that it seems as if they were never sent. The method is the first that can cloak data streams sent at the rapid rates typically seen in telecommunications systems. It opens the door to ultra-secure transmission schemes, and may also provide a way to better shield information from noise corruption (abstract). The researchers manipulated laser light in time to create regular periods with zero light intensity (a Talbot carpet) in which to hide data. Unfortunately, the current set up erases the data-adding event entirely from history. Though they are confident that future modifications will allow them, or others, to send secret messages successfully, the more immediate use of the technology will be to cut down crosstalk when multiple data streams share the same fibre."

GM Crop Producer Monsanto Using Data Analytics To Expand Its Footprint 128

Nerval's Lobster writes "Monsanto is more infamous for growing its genetically modified crops than its use of software, but a series of corporate acquisitions and a new emphasis on tech solutions has transformed it into a firm that acts more like an innovative IT vendor than an agribusiness giant. Jim McCarter (the Entrepreneur in Residence for Monsanto) recently detailed for an audience in St. Louis how the company's IT efforts are expanding. Monsanto's core projects generate huge amounts of bits, especially its genomic efforts, which are the focus of so much public attention. Other big data gobblers are the phenotypes of millions of DNA structures that describe the various biological properties of each plant, and the photographic imagery of crop fields. (All told, there are several tens of petabytes that need storage and analysis, a number that's doubling roughly every 16 months.) With all that tech muscle, the company has launched IT-based initiatives such as its FieldScripts software, which uses proprietary algorithms (fed with data from the FieldScripts Testing Network and Monsanto research) to recommend where to best plant corn hybrids. 'Just like Amazon has its recommendation engine for what book to buy, we will have our recommendations of what and how a grower should plant a particular crop,' said McCarter. 'All fields aren't uniform and shouldn't be planted uniformly either.' Despite its increasingly sophisticated use of data analytics in the name of greater crop yields, however, Monsanto faces pushback from various groups with an aversion to genetically modified food; a current ballot initiative in Washington State, for example, could result in genetically modified foods needing a label in order to go on sale here. The company has also inspired a 'March Against Monsanto,' which has been much in the news lately."

Cometary Impacts May Have Provided Key Elements of Life 85

trendspotter writes with news of research indicating that impact events might be responsible for seeding the Earth with reactive forms of the precursors to amino acids. From the article: "Early Earth was not very hospitable when it came to jump starting life. In fact, new research shows that life on Earth may have come from out of this world. Lawrence Livermore scientist Nir Goldman and University of Ontario Institute of Technology colleague Isaac Tamblyn (a former LLNL postdoc) found that icy comets that crashed into Earth millions of years ago could have produced life building organic compounds, including the building blocks of proteins and nucleobases pairs of DNA and RNA. Comets contain a variety of simple molecules, such as water, ammonia, methanol and carbon dioxide, and an impact event with a planetary surface would provide an abundant supply of energy to drive chemical reactions."

Quadcopter Guided By Thought — Accurately 79

ananyo writes "A toy quadcopter can be steered through an obstacle course by thought alone. The aircraft's pilot operates it remotely using a cap of electrodes to detect brainwaves that are translated into commands. Ultimately, the developers of the mind-controlled copter hope to adapt their technology for directing artificial robotic limbs and other medical devices." From the paper (PDF) abstract: "... we report a novel experiment of BCI controlling a robotic quadcopter in three-dimensional (3D) physical space using noninvasive scalp electroencephalogram (EEG) in human subjects. We then quantify the performance of this system using metrics suitable for asynchronous BCI. Lastly, we examine the impact that the operation of a real world device has on subjects’ control in comparison to a 2D virtual cursor task. Approach. ... Individual subjects were able to accurately acquire up to 90.5% of all valid targets presented while traveling at an average straight-line speed of 0.69 m s^(1)." This also appears to be the first time a Brain-Computer Interface was used to operate a flying device in 3D space. Also, there are several additional videos showing people operating the quadcopter.

New Drugs Trail Many Old Ones In Effectiveness Against Disease 230

Lasrick tips this report from Reuters: "Despite the more than $50 billion that U.S. pharmaceutical companies have spent every year since the mid-2000s to discover new medications, drugmakers have barely improved on old standbys developed decades ago. Research published on Monday showed that the effectiveness of new drugs, as measured by comparing the response of patients on those treatments to those taking a placebo, has plummeted since the 1970s. 'While experts agree that tougher trials and similar factors explain some of the decline in drugs' reported effectiveness, something real is going on here,' said Olfson. 'Physicians keep saying that many of the new things just aren't working as well,' and therefore prescribe antidepressant drugs called tricyclics (developed in the 1950s) instead of SSRIs (from the 1980s), or diuretics (invented in the 1920s) for high blood pressure instead of newer anti-hypertensives.'"

XCOR COO Warns That Proposed State Department Rule Could Cripple Space Tourism 105

MarkWhittington writes "Andrew Nelson, the chief operating officer of XCOR Aerospace, a company that proposes to take paying customers on suborbital jaunts on its Lynx rocketplane, posted some good news/bad news concerning some proposed rule changes from the State Department on June 3, 2013. On the good news side, the Department of State has proposed changes (PDF) that would move satellites from the Department of Defense's Munitions list, where they have been since 1999, to the Department of Commerce's commerce control list. 'This is a great step for the industry. Since the time commercial satellites were placed on the munitions list in 1999, the commercial satellite industry was almost wiped out.' On the bad news side, the State Department proposes to place commercial manned spacecraft on the DOD munitions list, making it very difficult if not impossible to fly them outside the United States. 'This is the same backward path provided to the US satellite manufacturing and launch community two decades ago that almost decimated that industry.'"

Lowest Mass Exoplanet Ever Directly Imaged. Probably. 43

The Bad Astronomer writes "Astronomers announced today that they have taken a direct image of the lowest mass exoplanet ever seen. HD 95086 b has a mass about 4 to 5 times that of Jupiter, and orbits a star 300 light years away that is slightly more massive and hotter than the Sun. The planet is not 100% confirmed, but it appears very likely to be real. If so, it's a hot gas giant, still cooling from its formation less than 20 million years ago. The picture, taken in the infrared, clearly shows the planet, making it one of fewer than a dozen such planets seen in actual telescopic images."

Proxima Centauri To Bend Starlight For Planet Hunt 23

astroengine writes "In October 2014 and again February 2016 Proxima Centauri, the closest star system to our Solar System, will pass in front of two distant stars allowing astronomers a rare opportunity to use Einstein's General Relativity to potentially detect hidden exoplanets around the star system. As Proxima Centauri blocks the distant starlight from our perspective, the gravitational field will bend the distant light to create a microlensing event. The transient brightening can then be analyzed and the gravitational presence of any worlds may be revealed. The research, announced Monday at the American Astronomical Society meeting in Indianapolis, has been submitted for publication in the Astrophysical Journal."

Genetic Switches Behind 'Love' Identified In Prairie Voles 102

ananyo writes "Researchers have shown for the first time that the act of mating induces permanent chemical modifications in the chromosomes (epigenetic changes), affecting the expression of genes that regulate sexual and monogamous behavior in prairie voles. Prairie voles have long been of interest to neuroscientists and endocrinologists who study the social behavior of animals, in part because this species forms monogamous pair bonds — essentially mating for life. The voles' pair bonding, sharing of parental roles and egalitarian nest building in couples makes them a good model for understanding the biology of monogamy and mating in humans (abstract)."

NASA Launches Second Robot Challenge 9

CowboyRobot writes "This week NASA kicks off its second Sample Return Robot Challenge, in which teams compete for a chance to win $1.5 million. Participants must demonstrate a self-operated robot capable of locating and collecting geologic samples from diverse terrain. Eleven teams from the U.S. and overseas gather for the challenge from June 5 through 7 at the Worcester Polytechnic Institute (WPI) in Worcester, Mass. The Sample Return Robot competition is part of NASA's Centennial Challenges program launched by the Space Technology Mission Directorate, which develops and tests hardware for use in NASA's future missions. NASA said the goal of the challenge is to encourage innovation in autonomous navigation and robotics technologies, which the agency could potentially use to explore a "variety of destinations in space" and in "industries and applications on Earth.""

Surgeries On Friday Are More Frequently Fatal 152

antdude writes "A British Medical Journal (BMJ) research report says that 'Surgeries on Friday Are More Frequently Fatal ... compared to those who opt for really bad Mondays, Britons who have a planned surgery on a Friday are 44 percent more likely to die. And the few patients who had a leisurely weekend surgery saw that number jump to 82 percent. The skeleton staff working on weekends might be to blame.'"

Researchers Determine Chemical Structure of HIV Capsid 90

adeelarshad82 writes "Researchers at the University of Illinois at Urbana-Champaign (UIUC) have determined the precise chemical structure of the HIV 'capsid,' a protein shell that protects the virus's genetic material and is a key to its virulence. The experiment involved mapping an incredible 64 million atoms to simulate the HIV capsid, pictured here. Interestingly no current HIV drugs target the HIV capsid and researchers believe that understanding the structure of the HIV capsid may hold the key to the development of new and more effective antiretroviral drugs. What makes this whole experiment even more fascinating is the use of Blue Waters, a Cray XK7 supercomputer with 3,000 Nvidia Tesla K20X GPU accelerators."

Never Mind the Epidemic, Who Gets Patent Rights For the Cure? 135

A virus that has so far killed nearly thirty people in seven countries faces a non-medical obstacle to treatment: Patents. Reader Presto Vivace writes with this excerpt from the Council on Foreign Relations: "At the center of the dispute is a Dutch laboratory that claims all rights to the genetic sequence of the Middle East Respiratory Syndrome coronavirus [MERS-CoV]. Saudi Arabia's deputy health minister, Ziad Memish, told the WHO meeting that "someone"--a reference to Egyptian virologist Ali Zaki--mailed a sample of the new SARS-like virus out of his country without government consent in June 2012, giving it to Dutch virologist Ron Fouchier of Erasmus Medical Center in Rotterdam."

Avatars Help Schizophrenics Gain Control of Voices In Their Heads 138

Zothecula writes "Imagine if there was a voice in your head that regularly threatened to harm you or your loved ones, or that even ordered you to do so yourself. Awful as that would be, such auditory hallucinations are one of the most common symptoms of schizophrenia, with approximately one in four sufferers continuing to experience them even after taking anti-psychotic drugs. Fortunately, scientists have recently helped some schizophrenics gain control of their condition, by turning those voices into interactive avatars."

Small Black Holes: Cloudy With a Chance of Better Visibility 27

Rambo Tribble writes "As reported by the BBC, astronomers are hoping to reap a black-hole-hunting windfall when a giant gas cloud passes through an area within our galaxy thought to contain numerous small black holes (abstract). When the cloud interacts with the black holes, the resultant emission of X-rays should allow scientists to finally confirm their existence. 'The idea is that as the cloud speeds past these small black holes — some slightly more massive than our Sun but just a few tens of km across — gas will spiral around them faster and faster, heating up to millions of degrees and emitting X-ray light. It is a bit like allowing a giant sink to empty through thousands of tiny drains and looking for any evidence of swirling water.'"

Big Asteroid (With Its Own Moon) To Have Closest Approach With Earth Today 87

An anonymous reader writes "Asteroid 1998 QE2 has an estimated diameter of 2.7 km. This asteroid will have a close approach with Earth at about 15.2 LD (Lunar Distances = ~384,000 kilometers) or 0.0392 AU (1 AU = ~150 million kilometers) at 2059 UT on 2013 May 31 and it will reach the peak magnitude ~10.8 on May 31 around 2300 UT." Radar images of the asteroid taken Wednesday show that 1998 QE2 has its own tiny moon, about 600 meters wide. Phil Plait explained how the images were taken, and what further information we gleaned from them. 'The very presence of the moon is a good thing. By measuring how long it takes to go around the primary, the mass of the primary can be found using math known for centuries (the more massive the big asteroid, the faster the moon will go around it at a given distance). We also know the size of the primary, so that means we can find its density, and therefore what it’s made of (probably mostly rock).'
