A video demonstration of the vulnerability here, using a temporary password. (credit: Kapil Haresh) This piece first appeared on Medium and is republished here with the permission of the author. It reveals a limitation in the way Apple approaches 2FA, which is most likely a deliberate decision. Apple engineers probably recognize that someone who loses their phone won’t be able to wipe data if 2FA is enforced, and this story is a good reminder of the pitfalls. As a graduate student studying cryptography, security and privacy (CrySP ), software engineering and human-computer interaction , I’ve learned a thing or two about security. Yet a couple of days back, I watched my entire digital life get violated and nearly wiped off the face of the Earth. That sounds like a bit of an exaggeration, but honestly it pretty much felt like that. Here’s the timeline of a cyber-attack I recently faced on Sunday, July 23, 2016 (all times are in Eastern Standard): That’s a pretty incidence matrix (credit: Kapil Haresh) 3:36pm— I was scribbling out an incidence matrix for a perfect hash family table on the whiteboard, explaining how the incidence matrix should be built to my friends. Ironically, this was a cryptography assignment for multicast encryption. Everything seemed fine until a rather odd sound started playing on my iPhone. I was pretty sure it was on silent, but I was quite surprised to see that it said “Find My iPhone Alert” on the lock screen. That was odd. Read 20 remaining paragraphs | Comments

Slashdot reader Paul Fernhout writes: FarmBot is an open-source gantry-crane-style outdoor robot for tending a garden bed. The project is crowdfunding a first production run and has raised US$561, 486 of their US$100, 000 goal — with one day left to go… The onboard control system is based around a Raspberry Pi 3 computer and an Arduino Mega 2560 Microcontroller. Many of the parts are 3D printable. Two years ago Slashdot covered the genesis of this project, describing its goal as simply “to increase food production by automating as much of it as possible.” Read more of this story at Slashdot.

An anonymous reader shares a CNET report: Australia is changing from “down under” to “down under and across a bit”. The country is shifting its longitude and latitude to fix a discrepancy with global satellite navigation systems. Government body Geoscience Australia is updating the Geocentric Datum of Australia, the country’s national coordinate system, to bring it in line with international data. The reason Australia is slightly out of whack with global systems is that the country moves about 7 centimetres (2.75 inches) per year due to the shifting of tectonic plates. Since 1994, when the data was last recorded, that’s added up to a misalignment of about a metre and a half. While that might not seem like much, various new technology requires location data to be pinpoint accurate. Self-driving cars, for example, must have infinitesimally precise location data to avoid accidents. Drones used for package delivery and driverless farming vehicles also require spot-on information.ABC has more details. Read more of this story at Slashdot.

Australia Has Moved 1.5 Metres, So It’s Updating Its Location For Self-Driving Cars
(credit: NASA ) Deep space travel takes a toll on the body—and it’s apparently something you can’t moon-walk off. Apollo astronauts who have ventured out of the protective magnetosphere of mother Earth appear to be dying of cardiovascular disease at a far higher rate than their counterparts—both those that have stayed grounded and those that only flew in the shielding embrace of low Earth orbit. Though the data is slim—based on only 77 astronauts total—researchers speculate that potent ionizing radiation in deep space may be to blame. That hypothesis was backed up in follow-up mouse studies which provided evidence that similar radiation exposure led to long-lasting damage to the rodents’ blood vessels. All of the data is published Thursday in the journal Scientific Reports . The study, while not definitive, may add an extra note of caution to the potential hazards of future attempts to fly to Mars and elsewhere in the cosmos. Read 9 remaining paragraphs | Comments

HughPickens.com writes: Seth Abramovitch reports in the Hollywood Reporter that actor and LGBT activist George Takei says Paramount’s plans to have Sulu’s character in the upcoming ‘Star Trek Beyond’ the first LGBTQ lead character in Star Trek history is out of step with what creator Gene Roddenberry would have wanted. [Roddenberry] “was a strong supporter of LGBT equality, ” says Takei, now 79. “But he said he has been pushing the envelope and walking a very tight rope — and if he pushed too hard, the show would not be on the air.” Takei says he’d much prefer that Sulu stay straight. “I’m delighted that there’s a gay character, ” says Takei. “Unfortunately, it’s a twisting of Gene’s creation, to which he put in so much thought. I think it’s really unfortunate.” The timeline logic of the new revelation is enough to befuddle even the most diehard of Trek enthusiasts, as the rebooted trilogy takes place before the action of the original series. In other words, assuming canon orthodoxy, this storyline suggest Sulu would have had to have first been gay and married, only to then go into the closet years later. Simon Pegg, who has co-written the latest Star Trek movie, as well as starring as Scotty, has responded to criticism by the actor George Takei at the film-makers’ decision to make the character he used to play openly gay. “He’s right, it is unfortunate, it’s unfortunate that the screen version of the most inclusive, tolerant universe in science fiction hasn’t featured an LGBT character until now. We could have introduced a new gay character, but he or she would have been primarily defined by their sexuality, seen as the ‘gay character, ‘ rather than simply for who they are, and isn’t that tokenism?” says Pegg. “Our Trek is an alternate timeline with alternate details. Whatever magic ingredient determines our sexuality was different for Sulu in our timeline. I like this idea because it suggests that in a hypothetical multiverse, across an infinite matrix of alternate realities, we are all LGBT somewhere.” Read more of this story at Slashdot.

An anonymous reader writes from a report via CNN: Helium is an incredibly important element that is used in everything from party balloons to MRI machines — it’s even used for nuclear power. For many years, there have been global shortages of the element. For example, Tokyo Disneyland once had to suspend sales of its helium balloons due to the shortages. The shortages are expected to come to an end now that researchers from Oxford and Durham universities have discovered a “world-class” helium gas field in Tanzania’s East African Rift Valley. They estimate that just one part of the reserve in Tanzania could be as large as 54 billion cubic feet (BCf), which is enough to fill more than 1.2 million medical MRI scanners. “To put this discovery into perspective, global consumption of helium is about 8 billion cubic feet (BCf) per year and the United States Federal Helium Reserve, which is the world’s largest supplier, has a current reserve of just 24.2 BCf, ” said University of Oxford’s Chris Ballentine, a professor with the Department of Earth Sciences. “Total known reserves in the USA are around 153 BCf. This is a game-changer for the future security of society’s helium needs and similar finds in the future may not be far away, ” Ballentine added. Read more of this story at Slashdot.

An anonymous reader writes from a report via ScienceAlert: Physicists have confirmed the existence of pear-shaped nuclei, which challenges the fundamental theories of physics that explain our Universe. “We’ve found these nuclei literally point towards a direction in space. This relates to a direction in time, providing there’s a well-defined direction in time and we will always travel from past to present, ” Marcus Scheck from the University of the West of Scotland told Kenneth MacDonald at BBC News. Until recently, it was generally accepted that nuclei of atoms could only be one of three shapes: spherical, discus, or rugby ball. The first discovery of a pear-shaped nucleus was back in 2013, when physicists at CERN discovered isotope Radium-224. Now, that find has been confirmed by a second study, which shows that the nucleus of the isotope Barium-144 is also asymmetrical and pear-shaped. In regard to time travel, Scheck says that this uneven distribution of mass and charge caused Barium-144’s nucleus to “point” in a certain direction in spacetime, and this bias could explain why time seems to only want to go from past to present, and not backwards, even if the laws of physics don’t care which way it goes.

Speaking at the National Press Club on Monday, Federal Communications Commission Chairman Tom Wheeler made an impassioned plea for the US to take the lead in developing a wireless 5G standard. “To seize the opportunities before us, we need the next generation of wireless connectivity – a fifth generation, or 5G, ” he said. What’s more he laid forth a plan to do it. On Thursday, Wheeler will seek to “open up” a swath of high-band spectrum for 5G applications; he’s calling it the Spectrum Frontiers proceeding. The FCC plans to use 200 MHz-wide chunks of high-band spectrum because, unlike lower frequencies, it can offer the gigabit per second throughput and sub-millisecond latency that 5G applications demand. 5G will usher in an Internet of Everything, Wheeler told the Press Club. “If something can be connected, it will be connected in a 5G world.” Wheeler cited various remote operation scenarios, such as surgeons using VR to operate on patients hundreds of miles away, to illustrate the need for ultrafast wireless connectivity. He expects the commission’s research to be completed and the proposal ready for a vote by July 14th. Should it be adopted, America would become the first nation on Earth to actively reserve frequency for 5G development. 5G networks will require a number of infrastructure updates, specifically a large number of small cell sites. To account for this, the FCC will streamline its environmental and historic preservation rules, which will allow local governments more flexibility in where they situate these devices. The commission will also reportedly take a collaborative approach to addressing the networks cybersecurity and will reach out to “all stakeholders”. Wheeler stated that he expects the private sector to lead this development and produce the necessary technical standards on its own. Verizon and AT&T have both already announced that they’ll begin testing 5G next year. And if what we saw at Mobile World Congress is any indication, they won’t be the last. “Turning innovators loose is far preferable to expecting committees and regulators to define the future.” Wheeler said. “We won’t wait for the standards to be first developed in the sometimes arduous standards-setting process or in a government-led activity.” That said, the end result of the coming 5G revolution is still very much up in the air. “I’ve listed some examples of what 5G makes possible, ” Wheeler told the crowd. “But if anyone tells you they know the details of what 5G will deliver, walk the other way.”

tomhath writes from a report via The Washington Post: The Tennessee Valley Authority’s (TVA) Watts Bar Unit 2 is the first nuclear reactor to come online since 1996, when the Watts Bar Unit 1 started operations. The new reactor is designed to add 1, 150 megawatts of electricity generating capacity to southeastern Tennessee. By summer’s end, authorities expect the new reactor at this complex along the Chickamauga Reservoir, a dammed section of the Tennessee River extending northward from Chattanooga, to steadily generate enough electricity to power 650, 000 homes. But while nuclear reactors account for the lion’s share of the carbon-free electricity generated in the United States, the industry faces this new set of circumstances in a state of near-crisis. A combination of very cheap natural gas and deregulated energy markets in some states has led to a growing number of plant closures in recent years. A new report from Bloomberg New Energy Finance says that renewable energy, including solar, wind and hydroelectric will overtake natural gas as an energy source by 2027.
