Submission + - MIT creates 3D-printing robot that can construct a home off-grid in 14 hours (mit.edu)

Kristine Lofgren writes: Home building hasn't changed much over the years, but leave it to MIT to take things to the next level. A new technology built at MIT can construct a simple dome structure in 14 hours and it's powered by solar panels, so you can take it to remote areas. MIT's 3D-printing robot can construct the entire basic structure of a building and can be customized to fit the local terrain in ways that traditional methods can't do. It even has a built-in scoop so it can prepare the building site and gather its own construction materials.

Submission + - Elon Musk on why he doesn't like flying cars: 'That is not an anxiety-reducing' (yahoo.com)

boley1 writes: Elon Musk on why he doesn't like flying cars: 'That is not an anxiety-reducing situation'.

According to Musk, the main challenges with flying cars are that they'll be noisy and generate lots of wind because of the downward force required to keep them in the air. Plus, there's an anxiety factor.

"Let's just say if something is flying over your head...that is not an anxiety-reducing situation," he said. "You don’t think to yourself 'Well, I feel better about today. You’re thinking'Is it going to come off and guillotine me as it comes flying past?'

Submission + - WikiLeaks Reveals The "Snowden Stopper": CIA Tool To Track Whistleblowers (zerohedge.com)

schwit1 writes: As the latest installment of it's 'Vault 7' series, WikiLeaks has just dropped a user manual describing a CIA project known as ‘Scribbles’ (a.k.a. the "Snowden Stopper"), a piece of software purportedly designed to allow the embedding of ‘web beacon’ tags into documents “likely to be stolen.” The web beacon tags are apparently able to collect information about an end user of a document and relay that information back to the beacon's creator without being detected. Per WikiLeaks' press release

But, the "Scribbles" user guide notes there is just one small problem with the program...it only works with Microsoft Office products. So, if end users use other programs such as OpenOffice of LibreOffice then the CIA's watermarks become visible to the end user and their cover is blown.

Submission + - SPAM: Higher sodium intake associated with lower blood pressure. You read that right.

schwit1 writes: In another blow against decades of accepted medical wisdom, one of the most prestigious, long-running studies reports that lowering sodium intake doesn’t reduce blood pressure.

The study also implies that most Americans are consuming a perfectly healthy amount of salt, the main source of sodium. But those who are salt-sensitive, about 20 to 25 percent of the population, still need to restrict salt intake.

Consuming fewer than 2,500 milligrams of sodium daily is actually associated with higher blood pressure, according to the Framingham Offspring Study report, given today. The American Heart Association recommends consuming no more than 2,300 milligrams of sodium daily, equal to a teaspoon of ordinary iodized table salt.

High blood pressure is a known risk factor for heart disease and stroke. Hence, lowering salt intake is supposed to lower blood pressure and thus reduce the risk of cardiovascular disease and stroke. But the study found that supposition to be unfounded.

Moreover, the lowest blood pressure was recorded by those who consumed 4,000 milligrams or more a day — amounts considered dangerously high by medical authorities such as the American Heart Association.

Submission + - NASA officially delays SLS first flight to 2019 (arstechnica.com)

schwit1 writes: Despite spending almost $19 billion and more than thirteen years of development, NASA today admitted that it will have to delay the first test flight of the SLS rocket from late 2018 to sometime in 2019.

“We agree with the GAO that maintaining a November 2018 launch readiness date is not in the best interest of the program, and we are in the process of establishing a new target in 2019,” wrote William Gerstenmaier, chief of NASA’s human spaceflight program. “Caution should be used in referencing the report on the specific technical issues, but the overall conclusions are valid.”

The competition between the big government SLS/Orion program and private commercial space is downright embarrassing to the government. While SLS continues to be delayed, even after more than a decade of work and billions of wasted dollars, SpaceX is gearing up for the first flight of Falcon Heavy this year. And they will be doing it despite the fact that Congress took money from the commercial private space effort, delaying its progress, in order to throw more money at SLS/Orion.

Submission + - Spying on Students in the Classroom (eff.org)

schwit1 writes: It seems a day doesn’t go by without another report of a company monitoring what we do on the Internet and selling that data to generate more revenue. And now the Electronic Frontier Foundation (EFF) has examined what happens to the data that's collected from students using technology in the classroom. They released the results of an extensive survey covering students in grades K-12.

What they found was that little work has been done to protect the privacy of the student information that is collected from both the classroom and from using the online software the schools issue for use at home on the students' own devices. They found that while many school districts have embraced technology and all of the benefits it can bring to the schools and students, often little thought has been given to one of the unintended consequences of this: the students' privacy.

The study was very extensive and took two years to complete. Virtually everything was examined, including what's being done along each point from the suppliers of hardware and software and the cloud services, to the schools and the students. They found that lots of data is being collected without permission and that it's easy for outside companies to access the data. They also discovered that there's little to prevent suppliers from sharing data with others, including advertisers.

Submission + - DNA-Based Test Can Spot Cancer Recurrence a Year Before Conventional Scans (theguardian.com)

An anonymous reader writes: A revolutionary blood test has been shown to diagnose the recurrence of cancer up to a year in advance of conventional scans in a major lung cancer trial. The test, known as a liquid biopsy, could buy crucial time for doctors by indicating that cancer is growing in the body when tumors are not yet detectable on CT scans and long before the patient becomes aware of physical symptoms. It works by detecting free-floating mutated DNA, released into the bloodstream by dying cancer cells. In the trial of 100 lung cancer patients, scientists saw precipitous rises in tumor DNA in the blood of patients who would go on to relapse months, or even a year, later. In the latest trial, reported in the journal Nature, 100 patients with non-small cell lung cancer were followed from diagnosis through surgery and chemotherapy, having blood tests every six to eight weeks. By analyzing the patchwork of genetic faults in cells across each tumor, scientists created personalized genomic templates for each patient. This was then compared to the DNA floating in their blood, to assess whether a fraction of it matched that seen in their tumor.

Submission + - SmartThings Has Access to Tens of Thousands of Private GitHub Repos (reddit.com)

An anonymous reader writes: After Samsung acquired SmartThings for a cool $200 million a few years ago, the company has been aggressively pushing for developers to enable GitHub access. At one time, the company boasted it had more than 20,000 developers on the platform. What most of those developers do not know is that the SmartThings integration is a blanket read on all repositories in your account. Why GitHub makes this an option, I have no idea. With all the turmoil over at Samsung lately, do you want that company to have access to all of your GitHub repositories? Have you checked what else has access to your repos lately?
