Researchers at MIT have built a system that allows robots to be corrected through thought and hand gestures. "The system monitors brain activity, determining if a person has noticed an error in the machine's work," reports Popular Mechanics. "If an error is detected, the system reverts over to human control. From that point, all it takes is a flick of the wrist to get the robot back on the right course." From the report: "This work combining EEG and EMG feedback enables natural human-robot interactions for a broader set of applications than we've been able to do before using only EEG feedback. By including muscle feedback, we can use gestures to command the robot spatially, with much more nuance and specificity," says CSAIL Director Daniela Rus, who supervised the work, in a press statement. EEG refers to electroencephalography, a type of biofeedback which uses real-time displays of brain activity to each self-regulation to the brain. EMG feedback refers to electromyography, which is the recording of the electrical activity of muscle tissue.
Earlier brain recognition systems required people to think in highly specific ways to achieve EEG or EMG recognition. What Rus' team realized is that when the human brain recognizes an error, it automatically releases a very specific signal all on its own. These signals are called error-related potentials (ErrPs). When the robotic system notices an ErrP signal in the human brain, it turns the robot over to human control.Read Replies (0)

Some U.S. lawmakers on both sides of the aisle have asked Google on Wednesday to reconsider its work with Chinese telecommunications firm Huawei, citing security concerns. Reuters reports: In a letter to Google Chief Executive Sundar Pichai, the lawmakers said Google recently decided not to renew "Project Maven," an artificial intelligence research partnership with the U.S. Department of Defense. "While we regret that Google did not want to continue a long and fruitful tradition of collaboration between the military and technology companies, we are even more disappointed that Google apparently is more willing to support the Chinese Communist Party than the U.S. military," they wrote. The letter was signed by Republican Senators Tom Cotton and Marco Rubio, Republican Representatives Michael Conaway and Liz Cheney, and Democratic Representative Dutch Ruppersberger.
"Like many U.S. companies, we have agreements with dozens of OEMs (manufacturers) around the world, including Huawei. We do not provide special access to Google user data as part of these agreement, and our agreements include privacy and security protections for use data," she said in an emailed statement.Read Replies (0)

An anonymous reader shares a study that finds contemporary meditation and yoga practices can actually inflate your ego. Quartz reports: In the paper, published online by University of Southampton and due to be published in the journal Psychological Science, researchers note that Buddhism's teachings that a meditation practice helps overcome the ego conflicts with U.S. psychologist William James's argument that practicing any skill breeds a sense of self-enhancement (the psychological term for inflated self-regard.) There was already a fair bit of evidence supporting William James's theory, broadly speaking, but a team of researchers from University Mannheim in Germany decided to test it specifically in the context of yoga and meditation.
They recruited yoga 93 students and, over a period of 15 weeks, regularly evaluated their sense of self-enhancement. They used several measures to do this. First, they assessed participants' level of self-enhancement by asking how they compared to the average yoga student in their class. (Comparisons to the average is the standard way of measuring self-enhancement.) Second, they had participants complete an inventory that assesses narcissistic tendencies, which asked participants to rate how deeply phrases like "I will be well-known for the good deeds I will have done" applied to them. And finally, they administered a self-esteem scale asking participants whether they agreed with statements like, "At the moment, I have high self-esteem." When students were evaluated in the hour after their yoga class, they showed significantly higher self-enhancement, according to all three measures, than when they hadn't done yoga in the previous 24 hours.Read Replies (0)

A Democratic assemblyman with financial ties to AT&T has gutted a new law that would serve as a gold standard for true net neutrality protection across the country. The bill SB 822 is expected to be voted on by the California State Assembly Communications and Conveyance committee on Wednesday, where it would go to the state assembly for a full vote, at which point it would become law if it passes. "But late Tuesday evening, Miguel Santiago, a California assemblyman and chair of the Communications and Conveyance committee, edited the bill to allow for gaping loopholes that benefit the telecommunications industry and make the net neutrality legislation toothless," reports Mashable. From the report: If Santiago doesn't remove his amendments, he would be the first California Democrat to side with the Trump administration to actively destroy net neutrality, according to Fight for the Future (an internet freedoms advocacy organization). Specifically, the amendments undermine net neutrality in a few ways. First, they would allow ISPs to charge any website a fee for people to be able to access it. Next, they would give some content (such as content owned by the provider) preferential treatment on cellular data. That means that some content would eat up cellular data, while others would be free or less impactful to access. There's a high likelihood that privileged content would be created by the network's parent company, since so many telecoms companies like Comcast and, recently, AT&T, now both own the actual content, and the way it's distributed. This loophole makes it likely that people wary about using up the data that they pay for would opt for the content privileged by their telecoms provider, which undermines consumer choice. And finally, Santiago's edits allow for throttling, which means intentionally slowing down content, but with a twist: Instead of slowing down the connection to consumer devices, the data is slowed at the website or service side, affecting everyone trying to access it.Read Replies (0)

Facebook announced today in a blog post that group administrators can start charging $4.99 to $29.99 a month for exclusive membership in certain groups. "Parenting, cooking, and home cleaning groups will be the first ones to get the new feature as part of an early test," reports The Verge. From the report: As it stands now, free groups will remain intact, but they will soon have the option to launch premium sub-groups. For instance, lifestyle blogger Sarah Mueller's Declutter My Home group is starting an Organize My Home group that costs $14.99 a month to join. And the Grown and Flown Parents group is making a College Admissions group that charges $29.99 for access to college counselors. Facebook says the new feature is so that group admins, who put a lot of time and dedication to growing their communities, can also earn money at the same time. The company also says admins could take the money they earn to create higher-quality content for the group as well, whether that be more posts, videos, or offline meet-ups and events. Facebook reportedly won't be getting a cut of the subscription fees.Read Replies (0)

Bloomberg New Energy Finance released a new report this week that estimates how electricity generation will change out to 2050. ArsTechnica: The clean energy analysis firm estimates that in a mere 33 years, the world will generate almost 50 percent of its electricity from renewable energy, and coal will make up just 11 percent of the total electricity mix. Add in hydroelectric power and nuclear energy, and greenhouse-gas-free electricity sources climb to 71 percent of the world's total electricity generation. The report doesn't offer a terribly bright future for nuclear, however, and after a period of contraction, the nuclear industry's contribution to electricity generation is expected to level off. Instead, falling photovoltaic (PV), wind, and battery costs will cause the dramatic shift in investment, Bloomberg New Energy Finance (BNEF) notes. "PV and wind are already cheaper than building new large-scale coal or gas plants," the 2018 report says. In addition, BNEF expects that more than $500 billion will be invested in batteries by 2050, with two-thirds of that investment going to installations on the grid and one-third of that investment happening at a residential level.Read Replies (0)

An anonymous reader shares a report: For a long time, China has been a dumping ground for the world's problematic plastics. In the 1990s, Chinese markets saw that discarded plastic could be profitably recreated into exportable bits and bobs -- and it was less expensive for international cities to send their waste to China than to deal with it themselves. China got cheap plastic and the exporting countries go rid of their trash. But in November 2017, China said enough. The country closed its doors to contaminated plastic, leaving the exports to be absorbed by neighboring countries like Vietnam, South Korea, and Thailand. And without the infrastructure to absorb all the waste that China is rejecting, the plastics are piling up. Between now and 2030, 111 million metric tons of trash -- straws, bags, water bottles -- will have nowhere to go, according to a paper published in Science Advances on Wednesday. That's as if every human on Earth contributed a quarter of their body mass in mostly single-use plastic polymers to a massive, abandoned pile of garbage.Read Replies (0)

The Oxford English Dictionary is asking the public to help it mine the regional differences of English around the world to expand its record of the language, with early submissions ranging from New Zealand's "munted" to Hawaii's "hammajang." From a report: Last year, a collaboration between the OED, the BBC and the Forward Arts Foundation to find and define local English words resulted in more than 100 new regional words and phrases being added to the dictionary, from Yorkshire's "ee bah gum" to the north east's "cuddy wifter," a left-handed person. Now, the OED is widening its search to English speakers around the world, with associate editor Eleanor Maier calling the early response "phenomenal," as editors begin to draft a range of suggestions for inclusion in the dictionary. These range from Hawaii's "hammajang," meaning "in a disorderly or shambolic state," to the Scottish word for a swimming costume, "dookers" or "duckers," and New Zealand's "munted," meaning "broken or wrecked." The OED is also looking to include the word "chopsy," a Welsh term for an overly talkative person; "frog-drowner," which Americans might use to describe a torrential downpour of rain; "brick", which means "very cold" to residents of New Jersey and New York City; and "round the Wrekin", meaning "in a lengthy or roundabout manner" in the Midlands. The dictionary has already found that, depending on location, a picture hanging askew might be described as "agley," "catawampous," "antigodlin" or "ahoo" by an English speaker, while a loved one could be called a "doy," "pet," "dou-dou," "bubele," "alanna" or "babber."Read Replies (0)

Joshua Rapp Learn, reporting for National Geographic: Critically endangered eels hyped up on cocaine could have trouble making a 3,700-mile trip to mate and reproduce -- new research warns. And while societies have long grappled with ways to cope with the use of illicit drugs, less understood are the downstream effects these drugs might have on other species after they enter the aquatic environment through wastewater. So, in the name of research, scientists pushed cocaine on European eels in labs for 50 days in a row, in an effort to monitor the effects of the experience on the fish. European eels have complex life patterns, spending 15 to 20 years in fresh or brackish water in European waterways before crossing the Atlantic Ocean to spawn in the Sargasso Sea just east of the Caribbean and the U.S. Eastern Seaboard. While the eels are also farmed for food, the wild population is considered critically endangered by the International Union for Conservation of Nature due to dams and other waterway changes that block their migrations, overfishing, and different types of water pollution. The eels are vulnerable to trace concentrations of cocaine, particularly in their early lives, according to the researchers of a study published in Science of the Total Environment.Read Replies (0)

Lindsay, a compact rectangle amid the lakes northeast of Toronto, is at the heart of one of the world's biggest tests of a guaranteed basic income. Technology Review: In a three-year pilot funded by the provincial government, about 4,000 people in Ontario are getting monthly stipends to boost them to at least 75 percent of the poverty line. That translates to a minimum annual income of $17,000 in Canadian dollars (about $13,000 US) for single people, $24,000 for married couples. Lindsay has about half the people in the pilot -- some 10 percent of the town's population. The report outlines that the Canadian province's vision for a basic income -- and the underlying experiment -- differs from that of the one we have seen in Silicon Valley. The report continues: The Canadians are testing it as an efficient antipoverty mechanism, a way to give a relatively small segment of the population more flexibility to find work and to strengthen other strands of the safety net. That's not what Silicon Valley seems to imagine, which is a universal basic income that placates broad swaths of the population. The most obvious problem with that idea? Math. Many economists concluded long ago that it would be too expensive, especially when compared with the cost of programs to create new jobs and train people for them. That's why the idea didn't take off after tests in the 1960s and '70s. It's largely why Finland recently abandoned a basic-income plan after a small test.Read Replies (0)
