Researchers Report Largest DNA Origami To Date

MTorrice (2611475) writes Bioengineers can harness DNA’s remarkable ability to self-assemble to build two- and three-dimensional nanostructures through DNA origami. Until now, researchers using this approach have been limited to building structures that are tens of square nanometers in size. Now a team reports the largest individual DNA origami structures to date, which reach sizes of hundreds of square nanometers. What’s more, they have developed a less expensive way to synthesize the DNA strands needed, overcoming a tremendous obstacle to scaling up the technology.

Emails Cast Unflattering Light On Internal Politics of Obamacare Website Rollo

An anonymous reader writes with this report from The Verge linking to and excerpting from a newly released report created for a committee in the U.S. House of Representatives, including portions of eight “damning emails” that offer an unflattering look at the rollout of the Obamacare website. The Government Office of Accountability released a report earlier this week detailing the security flaws in the site, but a report from the House Committee on Oversight and Government Reform released yesterday is even more damning. Titled, “Behind the Curtain of the HealthCare.gov Rollout,” the report fingers the Centers for Medicare and Medicaid Services, which oversaw the development of the site, and its parent Department of Health and Human Services. “Officials at CMS and HHS refused to admit to the public that the website was not on track to launch without significant functionality problems and substantial security risks,” the report says. “There is also evidence that the Administration, to this day, is continuing its efforts to shield ongoing problems with the website from public view.” Writes the submitter: “The evidence includes emails that show Obamacare officials more interested in keeping their problems from leaking to the press than working to fix them. This is both both a coverup and incompetence.”

Washington DC To Return To Automatic Metro Trains

Bruce66423 (1678196) writes with news of interest to anyone with reason to ride mass transit in the U.S., specifically on the D.C. Metro system: After a crash some five years ago, automatic operation was abandoned. Now however replacement of ‘faulty’ modules means that moving the whole system on to automatic operation can happen. One quote is depressing: “And because trains regularly lurch to a halt a few feet short of where they should be at platforms, Metrorail riders have grown accustomed to hearing an announcement while they’re waiting to board: ‘Stand clear. Train moving forward.’” That never happens on the London underground with human operators? What’s wrong with American drivers?

New "Crescent Bay" VR Headset Revealed and Demo’d At Oculus Connect

Oculus Rift revealed today its new ‘Crescent Bay’ prototype wearable display, at its inaugural Oculus Connect conference. (You can find more in the company’s blog too.) From Gamasutra’s coverage: The new headset has 360 degree tracking and integrated audio, as well as improved performance that allows better presence, says Iribe. It has higher resolution and a better refresh rate than even its recent DK2 headset. It’s also much lighter than earlier prototypes. The company has also licensed technology from RealSpace 3-D for improved 3D audio on Oculus moving forward. Audio is becoming a priority for the company, [CEO Brendan] ]Iribe said. Road to VR has a gushing hands-on review: One of the stand-out demos put me in front of an alien on some sort of Moon-like world. The alien was looking at me and speaking in an unfamiliar tongue. When I moved my head, its gaze followed me. Its big and detailed eyes, combined with reaction to me as I moved, imbued it with a sense of living that was really cool. Spaceships flew over head and drew my gaze behind me, leading me to look at some incredibly detailed scenery.

Is Google’s Non-Tax Based Public School Funding Cause For Celebration?

theodp (442580) writes “Google’s “flash-funding” of teachers’ projects via DonorsChoose continues to draw kudos from grateful mayors of the nation’s largest cities. The latest comes from Pittsburgh Mayor Bill Peduto (fresh from a Google-paid stay at the Google Zeitgeist resort), who joined Google officials at Taylor Allderdice HS, where Google announced it was ‘flash funding’ all Pittsburgh area teachers’ crowd-funding campaigns on DonorsChoose.org. DonorsChoose reports that Google spent $64,657 to fund projects for 10,924 Pittsburgh kids. While the not-quite-$6-a-student is nice, it does pale by comparison to the $56,742 Google is ponying up to send one L.A. teacher’s 34 students to London and Paris and the $35,858 it’s spending to take another L.A. teacher’s 52 kids to NYC, Gettysburg, and DC. So, is Google’s non-tax based public school funding — which includes gender-based funding as well as “begfunding” — cause for celebration?”

Ask Slashdot: Alternate Software For Use On Smartboards?

SmarterThanMe (1679358) writes Teacher here, you can call me Mr. SmarterThanMe. I have a fancy smartboard installed in my room. Smartboards allow me to show students a whole range of other stuff other than just whatever I’m writing. I can prepare instructions and activities before the lesson and just move through the boards. I can pull up some students’ work and display it through the projector. I can bring up some stimulus for use in a writing task. So much better than blackboards. Except the software that comes bundled with this particular brand of smartboard is ridiculously clunky. Without naming this particular piece of software, and highlighting its shortfalls, has anyone got any suggestions on alternatives (open source or otherwise)? The main features that I’d like are: Handwriting recognition The ability to make and use templates Grids or guides or *something* to be able to teach measurement I have gold star stickers for any good suggestions.

Video Released, Crowdfunding Underway For Axiom Open Source Cinema Camera

New submitter atagunov writes “Video clips have been released as crowdfunding starts for the world first open source cinematic videocam. “I am a filmmaker myself … I would like to have powerful tools that I know to have full control over and that I can tune and tweak,” says Sebastian Pichelhofer of Apertus. He is working on the Axiom Beta, the 2nd generation Apertus videocam, fully open sourced under GPL and OHL. It’s not cheap compared to consumer-grade cameras, but being not-cheap hasn’t stopped people from snapping up Joel Rubenstein’s Digital Bolex.

Why You Can’t Manufacture Like Apple

HughPickens.com writes Medium reports that although many startups want to design something that mimics the fit and finish of an Apple product, it’s a good way to go out of business. “What happened when Apple wanted to CNC machine a million MacBook bodies a year? They bought 10k CNC machines to do it. How about when they wanted to laser drill holes in MacBook Pros for the sleep light but only one company made a machine that could drill those 20 m holes in aluminum? It bought the company that made the machines and took all the inventory. And that time when they needed batteries to fit into a tiny machined housing but no manufacturer was willing to make batteries so thin? Apple made their own battery cells. From scratch.” Other things that Apple often does that can cause problems for a startup include white plastic (which is the most difficult color to mold), CNC machining at scale (too expensive), Laser drilled holes (far more difficult than it may seem), molded plastic packaging (recycled cardboard is your friend), and 4-color, double-walled, matte boxes + HD foam inserts (It’s not unusual for them to cost upwards of $12/unit at scale. And then they get thrown away.). “If you see a feature on an Apple device you want to copy, try to find it on another company’s product. If you do, it’s probably okay to design into your product. Otherwise, lower your expectations. I assure you it’ll be better for your startup.”
