University of California, Berkeley, To Delete Publicly Available Educational Content

In response to a U.S. Justice Department order that requires colleges and universities make website content accessible for citizens with disabilities and impairments, the University of California, Berkeley, will cut off public access to tens of thousands of video lectures and podcasts. Officials said making the videos and audio more accessible would have proven too costly in comparison to removing them. Inside Higher Ed reports: Today, the content is available to the public on YouTube, iTunes U and the university’s webcast.berkeley site. On March 15, the university will begin removing the more than 20, 000 audio and video files from those platforms — a process that will take three to five months — and require users sign in with University of California credentials to view or listen to them. The university will continue to offer massive open online courses on edX and said it plans to create new public content that is accessible to listeners or viewers with disabilities. The Justice Department, following an investigation in August, determined that the university was violating the Americans With Disabilities Act of 1990. The department reached that conclusion after receiving complaints from two employees of Gallaudet University, saying Berkeley’s free online educational content was inaccessible to blind and deaf people because of a lack of captions, screen reader compatibility and other issues. Cathy Koshland, vice chancellor for undergraduate education, made the announcement in a March 1 statement: “This move will also partially address recent findings by the Department of Justice, which suggests that the YouTube and iTunes U content meet higher accessibility standards as a condition of remaining publicly available. Finally, moving our content behind authentication allows us to better protect instructor intellectual property from ‘pirates’ who have reused content for personal profit without consent.” Read more of this story at Slashdot.

Professors Claim Passive Cooling Breakthrough Via Plastic Film

What if you could cool buildings without using electricity? charlesj68 brings word of “the development of a plastic film by two professors at the University of Colorado in Boulder that provides a passive cooling effect.” The film contains embedded glass beads that absorb and emit infrared in a wavelength that is not blocked by the atmosphere. Combining this with half-silvering to keep the sun from being the source of infrared absorption on the part of the beads, and you have a way of pumping heat at a claimed rate of 93 watts per square meter. The film is cheap to produce — about 50 cents per square meter — and could create indoor temperatures of 68 degrees when it’s 98.6 outside. “All the work is done by the huge temperature difference, about 290C, between the surface of the Earth and that of outer space, ” reports The Economist.

DNA ‘computers’ could lead to self-activated smart pills

Imagine a pill that knew if you were ill enough to need drugs, and wouldn’t release chemicals if it thought you didn’t need it. That’s the breakthrough that’s been made at Eindhoven University in the Netherlands by a team of researchers ld by Maarten Merkx. The team has harnessed the power of DNA itself to form an organic computer that performs crude calculations on the state of your health. When you get ill, or suffer from a chronic condition, doctors normally prescribe drugs to help you get better, but this is based on a set of generic guidelines. The idea is that a smart pill will be able to offer specific doses, tailored to your needs, reducing the risk of side effects and waste. The computation comes in the form of the DNA, which looks for molecules that it can react with as a form of data-gathering. Put simply, the pill will journey inside your body and sniff the local environment to decide if you need more medicine. Of course, like so many things at the bleeding edge of technology, it’s still early days for this form of treatment, but the potential is exciting. Source: TUE , Nature

Alaska Gets ‘Artificial Aurora’ As HAARP Antenna Array Listens Again

Freshly Exhumed quotes Hackaday: The famous HAARP antenna array is to be brought back into service for experiments by the University of Alaska. Built in the 1990s for the US Air Force’s High Frequency Active Auroral Research Program, the array is a 40-acre site containing a phased array of 180 high-frequency antennas and their associated high-power transmitters. Its purpose is to conduct research on charged particles in the upper atmosphere, but that hasn’t stopped an array of bizarre conspiracy theories. A university space physics researcher will actually create an artificial aurora starting Sunday (and continuing through Wednesday) to study how yjr atmosphere affects satellite-to-ground communications, and “observers throughout Alaska will have an opportunity to photograph the phenomenon, ” according to the University. “Under the right conditions, people can also listen to HAARP radio transmissions from virtually anywhere in the world using an inexpensive shortwave radio.” Read more of this story at Slashdot.

Patent Office Rules CRISPR Patents, Potentially Worth Billions, Belong To Broad Institute

According to a ruling by judges at the United States Patent and Trademark Office, the disputed patents on the gene-editing tool CRISPR belong to the Broad Institute of MIT and Harvard. “The ruling comes a little over two months after a high-profile court hearing, during which MIT and University of California, Berkeley heatedly argued about who should own CRISPR, ” The Verge reports. From their report: STAT News reported that the decision was one sentence long. The three judges decided that the Broad patents are different enough from the ones the University of California applied for that the Broad patents stand. The patent ruling suggests that the work done by Jennifer Doudna of the University of California and her colleagues on CRISPR wasn’t so groundbreaking as to make any other advance obvious. But that legal opinion isn’t how the science world views her work, STAT points out: “Doudna and her chief collaborator, Emmanuelle Charpentier, won the $3 million Breakthrough Prize in the life sciences in 2015, the $500, 000 Gruber Genetics Prize in 2015, and the $450, 000 Japan Prize in 2017, ” the outlet notes.

The world’s biggest telescope needs half a billion dollars more

GMTO It has been a long road for planners of the Giant Magellan Telescope, which will become the world’s largest telescope—if it’s completed on schedule. Casting of the first of seven mirrors, each formed from about 20 tons of borosilicate glass made from Florida sand, began way back in 2005. The project seems to finally be closing in on first light as the team amps up fundraising and construction efforts. The organizers of the telescope are gearing up for fundraising needed to bring the project to completion and have hired a new president with significant executive experience: Robert N. Shelton, a former president of the University of Arizona and provost and executive vice chancellor of the University of North Carolina at Chapel Hill. “Anyone who has been a president and a provost understands the importance of fundraising,” Shelton told Ars in an interview.

Surgical robot makes highly precise eye injection possible

For the first time ever, a team of eye surgeons were able to inject a thrombolytic drug directly into a patient’s retinal vein to dissolve a blood clot. It was a success despite the fact that the vein is as thin as human hair thanks to a surgical robot developed by researchers from KU Leuven , a university in Belgium. The condition they treated is called retinal vein occlusion, and it leads to reduced eyesight and blindness. At the moment, doctors can only suppress its effects with monthly eye injections, because the retinal vein itself is only around 0.1 millimeter wide. It’s just much too thin for manual injections when the drug has to be administered for 10 minutes straight. Professor Peter Stalmans, an eye surgeon at University Hospitals Leuven, said: “The current treatment for retinal vein occlusion costs society €32.000 per eye. This is a high price tag, considering that you’re only treating the side effects and that there is little more you can do than avoid reducing eyesight. The robotic device finally enables us to treat the cause of the thrombosis in the retina. I look forward to what is next: if we succeed, we will literally be able to make blind people see again.” To address the issue, the researchers created a robot that can help a surgeon insert the needle precisely and then hold it perfectly still. They also designed the 0.03 millimeter needle, which is three times thinner than human hair, needed to inject the drug into the tiny vein. According to the university, the method successfully dissolved the blood clot and the patient is now doing well. However, it’ll take some time before everyone else who has the condition can go through the same treatment: the surgery was merely part of the first phase of the method’s clinical trial. The surgeons have to replicate the procedure’s success on other patients and then study its effects in the trial’s second phase. Source: KU Leuven

1,000-year-old Native American structure was designed using sophisticated math

Sherry Towers A millennium ago, the Pueblo peoples were constructing incredible monuments and cities throughout the US Southwest. Among the most impressive structures they left behind is called the Sun Temple, in what is now Colorado’s Mesa Verde National Park . Probably the location for meetings and ceremonies, the Sun Temple is an enormous D-shaped building with walls that were once 11-15 feet high. Now, an applied mathematician has discovered something intriguing about the proportions used to lay out the temple and its internal structures. Physicist Sherry Towers is part of the Mathematical, Computational, and Modeling Sciences Group at Arizona State University, and she occasionally takes time away from physics to focus on the way mathematical patterns shape the social world. She got interested in the Sun Temple site because many archaeologists believe its structure might reveal whether the Pueblo peoples were using it for astronomy. But as Towers pored over satellite images of the area from Google Maps, the Sun Temple’s general shape kept drawing her attention. “I noticed in my site survey that the same measurements kept popping up over and over again,” she said in a release . “When I saw that the layout of the site’s key features also involved many geometrical shapes, I decided to take a closer look.” Read 5 remaining paragraphs | Comments

LA beats out SF to host George Lucas’ art museum

Unbeknownst to some, Los Angeles and San Francisco had been clashing for months on yet another front: Which would win the right to build an elaborate, expansive museum housing film ephemera and personal art collected by George Lucas. As is only proper for the nexus of cinema, Hollywood won the fight. Yes, the upcoming museum will feature choice souvenirs from the Star Wars franchise, but it aims to be a serious institution with the money to back it up. Lucas will allegedly front $1 billion himself in construction costs and art as well as the creation of a $400 million endowment fund. The 275, 000 sq ft building will sit in Exposition Park south of downtown, joining the California Science Center, Natural History Museum and California African American Museum. It will house over 10, 000 paintings and illustrations including works by Rockwell, N.C. Wyeth and R. Crumb, according to The Los Angeles Times . Canny fans will note that the future site of the George Lucas Museum of Narrative Art is blocks away from the University of Southern California campus, where he studied as a young filmmaker. It’ll also be an hour-drive away from another sizable monument to his legacy when Disneyland’s upcoming Star Wars Land eventually opens. Source: The Los Angeles Times

Amber’s sensors aim to save farmers’ grain from spoilage

CES is most known as a show for computers , cars and seriously strange stuff , but there’s no shortage of people here trying to solve big problems the rest of us have never heard of. Take Amber Agriculture for instance: run by students at the University of Illinois, the startup as developed a finger-sized sensor meant to be stuck inside silos to help farmers monitor the quality of their stored grain. What’s more, Amber’s approach falls in line with other big trends at the show. You’ve heard of the smart home — the Amber team is trying to help build the smart farm. The idea is simple enough — these sensors monitor temperature and humidity, along with the volatile compounds that signal how moist a farmer’s grain is. Since this is 2017, those farmers will be able to monitor that key data from their smartphones, and that sort of easy access should help them figure out the ideal time to sell and ship their crop. Here’s the thing, though: there’s more to this idea than just helping the world’s farmers demand the best possible prices. Amber co-founder Lucas Frye also believes that some serious long-term good could be possible if the company could work with farmers in countries where grain spoilage has been a pressing issue. Frye, a competent, low-key pitchman, said the startup’s vision is on some level about protecting our food supply. That said, smart moisture management won’t be able to fix every grain spoilage problem around the world. Consider India: spoilage and grain rot is a recurring problem there, but that’s thanks in large part to logistical issues like finding places to actually store those huge crop hauls. For now, though, global problems are taking a back seat while Amber makes sure everything works the way it’s supposed to. There’s no firm word on pricing yet, but that’s to be expected — after finalizing some design elements and striking some deals, the startup’s leaders are gearing up for its first set of field trials in early 2017. Click here to catch up on the latest news from CES 2017.
