mmell writes: Apparently, owning 700 acres of land in Hawaii isn't enough -- Mark Zuckerberg, founder of Facebook, has filed suit to force owners of several small parcels of land to sell to the highest bidder. The reason? These property owners are completely surrounded by Zuckerberg's land holdings and therefore have lawful easement to cross his property in order to get to theirs. Many of these land owners have held their land for generations, but seemingly Mr. Zuckerberg can not tolerate their presence so close to his private little slice of paradise. Landowners such as these came to own their land when their ancestors were "given" the land as Hawaiian natives. If successful in his "quiet title" court action, Mr. Zuckerberg will finally have his slice of Hawaii's beaches and tropical lands without having to deal with the pesky presence of neighbors who were on his land before he owned it. Who knew that Hawaiians were just another kind of Native Americans? CNBC reports: "The cases target a dozen small plots of so-called 'kuleana' lands that are inside the much larger property that Zuckerberg bought on Kauai. Kuleana lands are properties that were granted to native Hawaiians in the mid-1800. One suit, according to the Star-Advertiser, was filed against about 300 people who are descendants of an immigrant Portuguese sugar cane plantation worker who bought four parcels totaling two acres of land in 1894. One of that worker's great-grandchildren, Carlos Andrade, 72, lived on the property until recently, the paper said. But the retired university professor told the Star-Advertiser that he is helping Zuckerberg's case as a co-plaintiff in an effort to make sure the land is not surrendered to the county if no one in his extended clan steps up to take responsibility for paying property taxes on the plots."

An anonymous reader quotes a report from Ars Technica: Netflix has gleefully poked a stick at its competitors in the video streaming market, after revealing it had added more than seven million subscribers to its service in the last three months of 2016. HBO also got a special mention. In a letter to shareholders, the company's boss Reed Hastings teased the TV drama maker by noting that, if the BBC was willing to stream shows before they air on television, then maybe HBO -- which has rigidly stuck to its strategy of eking out episodes to viewers -- should do the same. He said: "[...] the BBC has become the first major linear network to announce plans to go binge-first with new seasons, favoring internet over linear viewers. We presume HBO is not far behind the BBC. In short, it's becoming an Internet TV world, which presents both challenges and opportunities for Netflix as we strive to earn screen time." But it's worth noting that HBO currently has an exclusive deal with Sky in the UK, Ireland, Germany, Austria, and Italy, allowing the broadcaster to have first-run rights on the likes of Game of Thrones and Westworld until 2020 -- so any such change isn't likely to happen in the near-term. Late last year, it struck a deal with Netflix rival Amazon, allowing Prime members in the US to sign up for a monthly HBO subscription. "We have a very successful partnership with this great company that continues to evolve," said HBO exec Sofia Chang in December. The company's HBO Now streaming service shows no sign of shifting strategy, either, with programs airing simultaneously on traditional TV and online.

Amazon is working on self-driving cars, according to a new patent that deals with the complex task of navigating reversible lanes. From a report on The Guardian: The patent, filed in November 2015 and granted on Tuesday, covers the problem of how to deal with reversible lanes, which change direction depending on the bulk of the traffic flow. This type of lane is typically used to manage commuter traffic into and out of cities, particularly in the US. Autonomous vehicles, the patent warns, "may not have information about reversible lanes when approaching a portion of a roadway that has reversible lane", leading to a worst-case scenario of them driving headfirst into oncoming traffic. More generally, the inability to plan for reversible lanes means cars and trucks can't optimize their routes by getting into the correct lane well in advance, something that could otherwise prove to be one of the benefits of self-driving cars. Amazon's solution to the problem could have much larger ramifications than simply dealing with highway traffic in large cities. The patent proposes a centralized roadway management system that can communicate with multiple self-driving cars to exchange information and coordinate vehicle movement at a large scale.

Students at elite colleges are even richer than experts realized, according to a new study based on millions of anonymous tax filings and tuition records. At 38 colleges in America, including five in the Ivy League -- Dartmouth, Princeton, Yale, Penn and Brown -- more students came from the top 1 percent of the income scale than from the entire bottom 60 percent. From a report on the NYTimes (alternate non-paywall link): Roughly one in four of the richest students attend an elite college -- universities that typically cluster toward the top of annual rankings (you can find more on our definition of "elite" at the bottom). In contrast, less than one-half of 1 percent of children from the bottom fifth of American families attend an elite college; less than half attend any college at all. Colleges often promote their role in helping poorer students rise in life, and their commitments to affordability. But some elite colleges have focused more on being affordable to low-income families than on expanding access. "Free tuition only helps if you can get in," said Danny Yagan, an assistant professor of economics at the University of California, Berkeley, and one of the authors of the study.

Netflix's boom in subscribers is a sign that the world is accepting internet TV, meaning without commercials and on-demand, said CEO Reed Hastings during an earnings call with investors. From a report: "The basic demand is increasing as people get more comfortable and more aware of Internet television where you don't get the commercial interruptions, where you get to watch where and when you want," said Hastings. Netflix reported $2.47 billion in revenue during Q4 2016, and earnings per share of 15 cents. The streaming giant wildly beat its original projections for subscriber additions, bringing in 7.05 million new customers compared to its Q3 estimate of 5.2 million. The majority of adds were from international viewers. Even though some shows -- like "Gilmore Girls" -- started as traditional TV shows before moving to Netflix, a large part of the draw for new subscribers came from original shows. Almost half of the most searched for shows this year were Netflix originals, said Ted Sarandos, chief content officer. The company has 42 launches coming up, including Marvel's "Iron Fist" and Drew Barrymore's zombie comedy "Santa Clarita Diet."

Sitting too much during the day has been linked to a host of diseases, from obesity to heart problems and diabetes, as well as early death. It's not hard to understand why: being inactive can contribute to weight gain, which in turn is a risk factor for heart attack, stroke, hypertension and unhealthy blood sugar levels. On top of everything else, sitting has detrimental effects on cells at the biological level, according to a new report published in the American Journal of Epidemiology. From a report on Time: In the new study, scientists led by Aladdin Shadyab, a post-doctoral fellow in family medicine and public health at the University of California San Diego, traced sitting's impact on the chromosomes. They took blood samples from nearly 1,500 older women enrolled in the Women's Health Initiative, a long-term study of chronic diseases in post-menopausal women, and focused on the telomeres: the tips of the tightly packed DNA in every cell. Previous studies have found that as cells divide and age, they lose bits of the telomeres, so the length of this region can be a marker for how old a cell (and indirectly the person the cells belong to) is. The researchers compared telomere length to how much the women exercised, to see if physical activity affected aging.

New submitter baalcat writes: A new study reported by Neuroscience News sheds light on how we learn to pay attention in order to make the most of our life experiences. From the report: "The Wizard of Oz told Dorothy to 'pay no attention to that man behind the curtain' in an effort to distract her, but a new Princeton University study sheds light on how people learn and make decisions in real-world situations. The findings could eventually contribute to improved teaching and learning and the treatment of mental and addiction disorders in which people's perspectives are dysfunctional or fractured. Participants in the study performed a multidimensional trial-and-error learning task, while researchers scanned their brains using functional magnetic resonance imaging (fMRI). The researchers found that selective attention is used to determine the value of different options. The results also showed that selective attention shapes what we learn when something unexpected happens. For example, if your pizza is better or worse than expected, you attribute the learning to whatever your attention was focused on and not to features you decided to ignore. Finally, the researchers found that what we learn through this process teaches us what to pay attention to, creating a feedback cycle -- we learn about what we attend to, and we attend to what we learned high values for. 'If we want to understand learning, we can't ignore the fact that learning is almost always done in a multidimensional 'cluttered' environment,' says senior author Yael Niv, an associate professor in psychology and the Princeton Neuroscience Institute. 'We want kids to listen to the teacher, but a lot is going on in the classroom -- there is so much to look at inside it and out the window. So, it's important to understand how exactly attention and learning interact and how they shape each other.'" The study has been published in the journal Neuron.

In an effort to improve air quality, the Chinese government has canceled over 100 coal-fired power plants in 11 provinces -- totaling a combined installed capacity of more than 100 gigawatts. Reuters reports: In a document issued on Jan. 14, financial media group Caixin reported, the National Energy Administration (NEA) suspended the coal projects, some of which were already under construction. The projects worth some 430 billion yuan ($62 billion) were to have been spread across provinces and autonomous regions including Xinjiang, Inner Mongolia, Shanxi, Gansu, Ningxia, Qinghai, Shaanxi and other northwestern areas. Putting the power projects on hold is a major step towards the government's effort to produce power from renewable sources such as solar and wind, and wean the country off coal, which accounts for the majority of the nation's power supply. To put it in perspective, some 130 GW of additional solar and wind power will be installed by 2020, equal to France's total renewable power generation capacity, said Frank Yu, principal consultant at Wood Mackenzie. "This shows the government is keeping its promise in curbing supplies of coal power," Yu said. Some of the projects will still go ahead, but not until 2025 and will likely replace outdated technology, he said.

An anonymous reader quotes a report from New Scientist: A female shark separated from her long-term mate has developed the ability to have babies on her own. Leonie the zebra shark (Stegostoma fasciatum) met her male partner at an aquarium in Townsville, Australia, in 1999. They had more than two dozen offspring together before he was moved to another tank in 2012. From then on, Leonie did not have any male contact. But in early 2016, she had three baby sharks. Intrigued, Christine Dudgeon at the University of Queensland in Brisbane, Australia, and her colleagues began fishing for answers. One possibility was that Leonie had been storing sperm from her ex and using it to fertilize her eggs. But genetic testing showed that the babies only carried DNA from their mum, indicating they had been conceived via asexual reproduction. Some vertebrate species have the ability to reproduce asexually even though they normally reproduce sexually. These include certain sharks, turkeys, Komodo dragons, snakes and rays. However, most reports have been in females who have never had male partners. In sharks, asexual reproduction can occur when a female's egg is fertilized by an adjacent cell known as a polar body, Dudgeon says. This also contains the female's genetic material, leading to "extreme inbreeding", she says. "It's not a strategy for surviving many generations because it reduces genetic diversity and adaptability." Nevertheless, it may be necessary at times when males are scarce. "It might be a holding-on mechanism," Dudgeon says. "Mum's genes get passed down from female to female until there are males available to mate with." It's possible that the switch from sexual to asexual reproduction is not that unusual; we just haven't known to look for it, Dudgeon says.

randomErr writes: 5.7 million adults in the United States have heart failure each year with about 41 million worldwide. Currently, treatment involves surgically implanting a mechanical pump, called a ventricular assist device (VAD), into the heart. The VAD helps maintains the heart's function. But patients with VADs are at high risk for getting blood clots and having a stroke. Researchers at Harvard University and Boston Children's Hospital have created a soft robotic sleeve that doesn't have to be implanted. The robotic sleeve slips around the outside of the heart, squeezing it in sync with the natural rhythm. "This work represents an exciting proof of concept result for this soft robot, demonstrating that it can safely interact with soft tissue and lead to improvements in cardiac function," Conor Walsh, said in a press statement. Seeker reports: "The sleeve they developed is made from thin silicone and attaches to the outside of the heart with a combination of suction devices and sutures. It relies on soft, air-powered actuators that twist and compress in a way that's similar to the outer layer of muscle of a human heart. A gel coating reduces any friction between the sleeve and the organ. Because the sleeve is soft and flexible, it can be customized to fit not just the size and shape of individual hearts, but augment the organ's weaknesses. For example, if a patient's heart is weaker on the left side than the right, the sleeve can be tuned to squeeze with more authority on the left side. As the organ gains strength, the device can be adjusted." The study has been published in the journal Science Translational Medicine.
