An anonymous reader writes "A meta-study published yesterday looked at over 12,000 peer-reviewed papers on climate science that appeared in journals between 1991 and 2011. The papers were evaluated and categorized by how they implicitly or explicitly endorsed humans as a contributing cause of global warming. The meta-study found that an overwhelming 97.1% of the papers that took a stance endorsed human-cause global warming. They also asked the 1,200 of the scientists involved in the research to self-evaluate their own studies, with nearly identical results. In the interest of transparency, the meta-study results were published in an open access journal, and the researchers set up a website so that anybody can check their results. From the article: '... a memo from communications strategist Frank Luntz leaked in 2002 advised Republicans, "Should the public come to believe that the scientific issues are settled, their views about global warming will change accordingly. Therefore, you need to continue to make the lack of scientific certainty a primary issue in the debate." This campaign has been successful. A 2012 poll from U.S. Pew Research Center found less than half of Americans thought scientists agreed humans were causing global warming. The media has assisted in this public misconception, with most climate stories "balanced" with a "skeptic" perspective. However, this results in making the 2–3% seem like 50%. In trying to achieve "balance," the media has actually created a very unbalanced perception of reality. As a result, people believe scientists are still split about what's causing global warming, and therefore there is not nearly enough public support or motivation to solve the problem.'"

sciencehabit writes "If you are one of the 20% of healthy adults who struggle with basic arithmetic, simple tasks like splitting the dinner bill can be excruciating. Now, a new study suggests that a gentle, painless electrical current applied to the brain can boost math performance for up to 6 months. Researchers don't fully understand how it works, however, and there could be side effects." We've covered various other potential benefits to having your brain shocked.

An anonymous reader sends this excerpt from Wired: "[Henry] Markram was proposing a project that has bedeviled AI researchers for decades, that most had presumed was impossible. He wanted to build a working mind from the ground up. ... The self-assured scientist claims that the only thing preventing scientists from understanding the human brain in its entirety — from the molecular level all the way to the mystery of consciousness — is a lack of ambition. If only neuroscience would follow his lead, he insists, his Human Brain Project could simulate the functions of all 86 billion neurons in the human brain, and the 100 trillion connections that link them. And once that's done, once you've built a plug-and-play brain, anything is possible. You could take it apart to figure out the causes of brain diseases. You could rig it to robotics and develop a whole new range of intelligent technologies. You could strap on a pair of virtual reality glasses and experience a brain other than your own."

Today The New Yorker unveiled a project called Strongbox, which aims to let sources share tips and leaks with the news organization in a secure manner. It makes use of the TOR network and encrypts file uploads with PGP. Once the files are uploaded, they're transferred via thumb-drive to a laptop that isn't connected to the internet, which is erased every time it is powered on and booted with a live CD. The publication won't record any details about your visit, so even a government request to look at their records will fail to find any useful information. "There’s a growing technology gap: phone records, e-mail, computer forensics, and outright hacking are valuable weapons for anyone looking to identify a journalist’s source. With some exceptions, the press has done little to keep pace: our information-security efforts tend to gravitate toward the parts of our infrastructure that accept credit cards." Strongbox is actually just The New Yorker's version of a secure information-sharing platform called DeadDrop, built by Aaron Swartz shortly before his death. DeadDrop is free software.

TheSync writes "The long-awaited remake of Carl Sagan's amazing Cosmos series, Cosmos: A Space-Time Odyssey, will be coming to Fox television next year. It will star astrophysicist Neil deGrasse Tyson. Surprisingly, Seth MacFarlane of Family Guy fame is an executive producer. MacFarlane was introduced to Carl Sagan's widow Ann Druyan by deGrasse Tyson, and MacFarlane helped them pitch the show to Fox executives."

An anonymous reader writes "Worldwide levels of the chief greenhouse gas that causes global warming have hit a milestone, reaching an amount never before encountered by humans, federal scientists said. Carbon dioxide was measured at 400 parts per million at the oldest monitoring station in Hawaii, which sets the global benchmark. More than half of plants and a third of animal species are likely to see their living space halved by 2080 if current trends continue."

An anonymous reader writes "With the personal robotics revolution imminent, a law professor and a roboticist (called Professor Smart!) argue that the law needs to think about robots properly. In particular, they say we should avoid 'the Android Fallacy' — the idea that robots are just like us, only synthetic. 'Even in research labs, cameras are described as "eyes," robots are "scared" of obstacles, and they need to "think" about what to do next. This projection of human attributes is dangerous when trying to design legislation for robots. Robots are, and for many years will remain, tools. ... As the autonomy of the system increases, it becomes harder and harder to form the connection between the inputs (your commands) and the outputs (the robot's behavior), but it exists, and is deterministic. The same set of inputs will generate the same set of outputs every time. The problem, however, is that the robot will never see exactly the same input twice. ... The problem is that this different behavior in apparently similar situations can be interpreted as "free will" or agency on the part of the robot. While this mental agency is part of our definition of a robot, it is vital for us to remember what is causing this agency. Members of the general public might not know, or even care, but we must always keep it in mind when designing legislation. Failure to do so might lead us to design legislation based on the form of a robot, and not the function. This would be a grave mistake."

Titus Andronicus writes "Today, NOAA reported, 'On May 9, the daily mean concentration of carbon dioxide in the atmosphere of Mauna Loa, Hawaii, surpassed 400 parts per million for the first time since measurements began in 1958.' For comparison, over the last 800,000 years, CO2 has ranged from roughly 180 ppm to 280 ppm. 'For the entire period of human civilization, roughly 8,000 years, the carbon dioxide level was relatively stable near that upper bound. But the burning of fossil fuels has caused a 41 percent increase in the heat-trapping gas since the Industrial Revolution, a mere geological instant, and scientists say the climate is beginning to react, though they expect far larger changes in the future.' The last time Earth had 400 ppm was probably more than 3 megayears ago."

hessian writes with a story at Wired (excerpt below) about a project from Drew Endy of the International Open Facility Advancing Biotechnology, or BIOFAB, to standardize a programming language connecting genetic information from DNA to the cell components that DNA can create. "The BIOFAB project is still in the early stages. Endy and the team are creating the most basic of building blocks — the 'grammar' for the language. Their latest achievement, recently reported in the journal Science, has been to create a way of controlling and amplifying the signals sent from the genome to the cell. Endy compares this process to an old fashioned telegraph. 'If you want to send a telegraph from San Francisco to Los Angeles, the signals would get degraded along the wire,' he says. "At some point, you have to have a relay system that would detect the signals before they completely went to noise and then amplify them back up to keep sending them along their way.""

ananyo writes "Researchers have tagged every single worker in entire colonies and used a computer to track them, accumulating what they say is the largest-ever data set on ant interactions. The biologists have found that the workers fall into three social groups that perform different roles: nursing the queen and young; cleaning the colony; and foraging for food. The insects, they found, tend to graduate from one group to another as they age. By creating heat maps to represent the workers’ positions, Mersch's team showed that nurses and foragers stick to their own company and seldom mix, even if the colony’s entrance and brood chamber are close together (abstract). Cleaners are more widely dispersed, patrolling the whole colony and interacting with both of the other groups. 'The ants can probably be in any place within their enclosures in less than a minute,' says Mersch, 'but even in these simple spaces, they organize into these spatial groups.'"

Zothecula writes "The Global Positioning System (GPS) has proved a boon for those with a bad sense of direction, but the satellite-based system isn't without its shortcomings. Something as simple as going indoors or entering a tunnel can render the system useless. That might be inconvenient for civilians, but it's potentially disastrous to military users, for whom the system was originally built. DARPA is addressing such concerns with the development of a self-sufficient navigation system that can aid navigation when GPS is temporarily unavailable."

Velcroman1 writes "The Pentagon has plans to deploy its first ever ship-mounted laser next year, a disruptive, cutting-edge weapon capable of obliterating small boats and unmanned aerial vehicles with a blast of infrared energy. Navy officials announced Monday that in early 2014, a solid-state laser prototype will be mounted to the fantail of the USS Ponce and sent to the 5th fleet region in the Middle East for real-world experience. 'It operates much like a blowtorch ... with an unlimited magazine,' one official said."
