Tesla recall covers 123,000 pre-April 2016 Model S EVs

While Tesla’s current-day Model 3 production tries to keep up with demand, the company is dealing with an issue affecting earlier cars. Today it announced a recall affecting every Model S built before April 2016. That adds up to about 123,000 vehicles worldwide that it plans to retrofit with new power steering bolts because it has “observed excessive corrosion in the power steering bolts, though only in very cold climates, particularly those that frequently use calcium or magnesium road salts, rather than sodium chloride (table salt).”

According to Tesla, it’s initiating this recall (similar to others it has done in the past) even though it estimates that fewer than 0.2 percent of vehicles will exhibit this issue. In an email to owners it explained that if the bolts fail then the steering would still work, but with lost or reduced power assist. I’ve experienced this while driving and can attest that it’s something you should probably hope to avoid. There’s a sizeable thread on Tesla Motors Club showing at least one vehicle this happened to, but with less than an hour of service it should be preventable on other cars.

Leaked Facebook memo: ‘ugly truth’ justified any growth tactics

Buzzfeed has published an internal Facebook memo entitled “The Ugly” from 2016 that shows just how much emphasis the social network places on growth above safety, privacy and everything else. Written by Facebook VP Andrew “Boz” Bosworth, one of Mark Zuckerberg’s staunchest allies, the memo tries to defend the social network’s “questionable contact importing practices” and pretty much takes a very “ends justify the means” tone. Part of the memo reads:

“…Maybe someone finds love. Maybe it even saves the life of someone on the brink of suicide.

So we connect more people

That can be bad if they make it negative. Maybe it costs a life by exposing someone to bullies. Maybe someone dies in a terrorist attack coordinated on our tools.

And still we connect people.

The ugly truth is that we believe in connecting people so deeply that anything that allows us to connect more people more often is *de facto* good. It is perhaps the only area where the metrics do tell the true story as far as we are concerned.

That isn’t something we are doing for ourselves. Or for our stock price (ha!). It is literally just what we do. We connect people. Period.

That’s why all the work we do in growth is justified. All the questionable contact importing practices. All the subtle language that helps people stay searchable by friends. All of the work we do to bring more communication in. The work we will likely have to do in China some day. All of it.”

Based on those words, Facebook’s top execs knew the issues that could arise from the way its platform works. In fact, as Buzzfeed noted, Boz posted the memo a day after Facebook Live captured the moment when a man from Chicago was shot to death. Shortly after that, a terrorist who posted about his plans to die as a martyr on Facebook stabbed and murdered an Israeli teen.

The memo shows the social network in an even worse light than before, considering its messsage. Facebook has been under fire more than usual ever since Cambridge Analytica’s secret data collection was exposed to the public. An executive defending its “questionable contact importing practices” (even if it is in a 2-year-old memo) is definitely not a good thing.

A former senior employee told Buzzfeed that the note “speaks to the majority of Facebook employee views,” but not everyone within the company believes growth should be everything: at least one engineer said it became a significant factor in his decision to leave. Former employee Alec Muffett said that an underrepresented portion of the company’s Engineering community really do care about user privacy.

As a response to the memo’s release, Boz claimed in a statement posted on Twitter that he didn’t actually agree with it when he wrote it, and he doesn’t agree with it today. He said its purpose was to surface the issues he thought deserved more discussion within the company:

Facebook chief Mark Zuckerberg also denied that the social network doesn’t care if someone loses a life or if people’s data are collected, so long as it connects more and more people, telling Buzzfeed in a statement:

“We’ve never believed the ends justify the means. We recognize that connecting people isn’t enough by itself. We also need to work to bring people closer together. We changed our whole mission and company focus to reflect this last year.”

Shred like a cyborg with this endurance-boosting exoskeleton for skiers

Whether it’s the workplace, war zones, or the home, exoskeletons are being used in a wide variety of settings and applications here in 2018. The latest? A new prototype exoskeleton, created by Roam Robotics, that’s designed to help wearers on ski slopes. Resembling a pair of leg braces with a connected backpack, the wearable device works by effortlessly replicating wearers’ movements. It does this using built-in, air-filled bladders to absorb the shock of impacts, and thereby protect skiers’ knees.

“Think of them as lightweight shock absorbers for your legs,” Roam Robotics CEO Tim Swift told Digital Trends. “There is a lightweight brace on each leg, which is connected to the corresponding boot. Both legs are powered by a lightweight backpack worn by the skier. As a skier needs support — during turns, stops, or whatever — the product provides that support.”

Swift said that he realized early on that exoskeletons were the way of the future. However, he also realized that it’s important to reduce their size and cost to make them the mainstream product they can be. As a result, he’s worked to replace the metal and motors of conventional systems with fabric and air, as can be seen with this creation.

So when can you get your hands (or, more accurately, feet) on this wearable device? “It will be rolled out in two main phases,” Swift continued. “For this coming season, a limited number of our ski product will be available at ski resorts in Utah and Northern California. They’ll be available through rentals with a small number of pilot devices available for purchase. We then hope to offer general availability to one and all for the 2019-2020 ski season.”

If you’re interested, you can pay $99 to reserve a unit, with the final price likely to fall in the $2,000-$2,500 range.

“We feel it will appeal to a wide variety of skiers,” Swift said. “In our initial testing, it’s helped skiers across a wide spectrum. If someone is already a strong skier, it helps them ski even longer with less exertion; if someone is an intermediate or beginning skier, it provides the support they need to ski longer and with better form.”

The ‘fog harp’ pulls water out of thin air, could help drought-prone communities

Brook Kennedy / Virginia Tech

Harvesting water from fog isn’t just a chore for young Luke Skywalker — it’s become an important part of bringing clean water to people living in drought-prone climates across the globe. The problem is that harvesting tools can be pretty inefficient.

Now, engineers from Virginia Technical University have designed a device that may be able to extract three times as much water from fog as previous tools. They’re calling the device the “fog harp” because the secret is in the way its array of parallel wires lines up like the strings of the instrument.

Most fog harvesters used today are massive nets that capture water droplets blown in by the wind. The droplets merge on the net and then stream down to a collection container at the bottom. If the net’s holes are too large, the droplets sneak through. If they’re too small, the holes can get clogged.

“What we demonstrated here is that using a ‘harp’ geometry, rather than nets, can solve the clogging problem to maximize the efficiency of fog harvesters,” Jonathan Boreyko, a Virginia Tech engineer who worked on the project, told Digital Trends. “By only having vertical, parallel wires, the droplets are able to slide down into the collector at very small sizes, preventing clogging even when small wires are used. So our harps can both catch the fog efficiently from the air, and avoid the clogging problem that plagues conventional nets.”

Some four billion people face severe water scarcity, according to a report from 2016, and their situation may worsen if the effects of climate change intensify. Since the 1980s, fog nets have helped drought-prone communities with access to low, moving fog, with the largest fog nets able to collect some 6,000 liters of water each day.

In the lab, the fog harp was able to increase water capture threefold compared to traditional devices. The current fog harp prototype is three feet by three feet, but the Virginia Tech team aims to increase the size in future iterations. By overcoming the constraints of traditional fog nets, the team hopes the fog harp will offer a tool that effectively captures droplets and avoids clogging.

“Fog harvesting is already used to obtain fresh water in arid regions, particularly along the coastal regions of South America and Africa,” Boreyko said. “When rainfall is scarce, fog becomes an invaluable source of water for drinking and agricultural purposes. Many desert animals and plants know this too, for example the pointy needles of cacti are highly efficient at capturing fog from the air.”

A paper describing the project was published this week in the journal ACS Applied Materials & Interfaces.

Latest Festo creations include a bionic bat and somersaulting robo-spider

We sure love nature-inspired robots a whole lot, and German automation company Festo is one of the most exciting companies working in this space. Its latest creations are two of its greatest yet: A BionicWheelBot robotic spider that resembles a Star Wars battle droid and a BionicFlyingFox which is, well, pretty much what its name suggests.

The BionicWheelbot was inspired by the flic-flac spider and its highly unusual way of moving, which includes a combination of walking, somersaulting and rolling on the ground. When it’s not busy scampering, the robot — which is powered by 15 motors — begins its rolling action by bending three legs on each side of its body to form a wheel. Two additional legs then extend, pushing the rolled-up spider off the ground, and forward. Doing so allows it to move over rougher ground at high speeds, even including uphill slopes.

The BionicFlyingFox, meanwhile, is a 580g creation with a 3D-milled foam body, carbon fiber skeleton, and 228cm wingspan — comprised of a wafer-thin, ultralight membrane material. The robot doesn’t just look like a real actual flying fox (aka a fruit bat), but can actually fly by flapping its wings in a realistic approximation of the genuine article. It’s launched via remote control but can then carry out its actual flight using an autopilot system — aided by infrared cameras built into its legs and wing tips.

Sadly, you won’t be able to buy either robot anytime soon. “Both projects are tech demos so there won’t be a real-world application for them — maybe a bit similar to concept cars in the automotive industry,” Dr. Elias Knubben, head of corporate bionic projects at Festo, told Digital Trends. “Nevertheless we’re trying to transfer the knowledge gained in the development of the bionic projects on product-related topics like energy efficiency and lightweight construction, so we can offer more efficient products and solutions to our partners and customers.”

Ultimately, Knubben said that the goal is to show off the company’s technology — and hopefully to inspire kids about the possibilities offered by science and technology in the process. We have to admit that that is a pretty good rationale for creating these critters!

Drug enforcement agency turns to A.I. to help sniff out doping athletes

In the constant battle between doping athletes and the officials trying to catch them, the athletes have almost always remained ahead of the curve. They’re the better-funded side in the war and can stay ahead of the latest testing methods that regulatory agencies are using. Most notably, in cycling, it’s an open secret that many of the sport’s athletes are on some kind of doping regimen. Lance Armstrong, the disgraced American cyclist who became the sport’s most popular figure before admitting to years of doping, was able to pass drug tests throughout his career despite being the most tested athlete on the planet.

So, the testing agencies are in dire need of help. Hoping to narrow the divide between the cheaters and the testing methods is the World Anti-Doping Agency (WADA), which recently announced it would begin using artificial intelligence systems to help flag suspected cheaters across all sports.

“There’s a lot of data that is being collected in anti-doping — whether it is through the [athlete’s biological] passports, through the tests, through the results of the athletes,” WADA Director Olivier Niggli told iNews. “If you manage to create a system that will meaningfully use this data, I think you can create some very powerful tools.”

WADA has lamented that its lack of resoures (both in personnel and finances) makes its job of catching doping athletes difficult much of the time. With A.I., the agency would be able to sift through an exponetial amount of extra data and subsequently raise red flags when it catches suspect patterns in an athlete’s performance and/or testing results. While the A.I. would be able to highlight who might be using performance-enhancing drugs, it would not be considered evidence of cheating. Instead, that highlighted athlete might subsequently go through a more rigorous drug-testing regimen as a result of being flagged by the computer.

“Only sophisticated algorithms would be able to spot the differences, which would allow the anti-doping organizations to focus on the right individuals,” Niggli said.

There are not a whole lot of specifics on the program yet as WADA will be testing a few pilot programs in the coming years. It’s likely going to take time before WADA might see real results from its new efforts.

“I hope that in five years we will be much better at analyzing all this data that we already have and are already collected,” Niggli said.

Scientists nix Alzheimer’s-causing brain plaques in mice. Could humans be next?

Alzheimer’s disease is the most common form of dementia, affecting roughly 5.7 million Americans at this moment. In 2018, Alzheimer’s and other dementias will cost the U.S. an estimated $277 billion — not to mention the immeasurable amount of emotion labor it inflicts on patients and their careers. Unfortunately, right now it is an incurable disease for those affected by it. While that will remain true for the time being, a promising new piece of research suggests that there may soon be a way to better treat or even prevent the disease altogether. In experiments with mice, researchers at Washington University School of Medicine have demonstrated that it is possible to remove the plaques which begin forming in the brains of future Alzheimer’s patients, sometimes years before the disease manifests.

These sticky masses are called amyloid plaques. As they form in the brain, they damage nearby cells. The plaques are made up of a brain protein called amyloid beta, along with another Alzheimer’s protein called Apolipoprotein E (ApoE). In their study, the Washington University researchers demonstrated that a DNA-based compound can be made to target ApoE in a way that also removes the plaques. It does this without removing the ApoE protein which is present in our blood and brain.

The DNA-based compound is an antibody called HAE-4. It was given to the mice in the study for six weeks and was found to cut the level of plaques in half. It could represent a new treatment for Alzheimer’s, without the side effects of some current alternatives.

“It is possible that what we have shown in mice with anti-ApoE antibodies in the future could move into human trials,” Dr. David Holtzman, head of the Department of Neurology, told Digital Trends. “Part of this will have to do with whether the effects we have seen in mice is similar to what is seen with anti-amyloid beta antibodies, but yet has less side effects. That remains to be determined.”

While it’s still far too soon to start celebrating the idea of a medicine people could proactively take to delay or stop the onset of Alzheimer’s, this still represents incredibly exciting research. Let’s hope that the subsequent steps prove as promising as the initial developments.

ProtonMail brings encrypted contacts to its mobile email app

ProtonMail’s encrypted contacts are now readily available beyond the web — the company has updated its Android and iOS email apps to add the privacy-minded contacts manager. It uses zero-access encryption to prevent everyone but you (yes, including ProtonMail) from seeing anything besides a name and email address, and includes digital signatures to check for signs of tampering. It’s pitched as ideal for journalists who may need to protect their contacts, but it could be just as important to you if you’re worried that a thief might use your contacts as a burglary hit list.

Notably, this is also the first time the mobile app has had a full contacts manager. The upgrade makes ProtonMail a more practical option if you spend most of your computing time on smartphones than PCs. You’ll still want to be extra-cautious even with encrypted contacts in place, but this will at least help you rest a little easier.

Lindsay Lohan’s ‘Grand Theft Auto’ suit is on the road to nowhere

Lindsay Lohan has lost the appeal for her lawsuit against Take-Two Interactive, which alleged that the company’s studio Rockstar Games used her likeness without permission for a character in Grand Theft Auto V. The case was originally dismissed back in 2016 because, well, it’s legal to parody people in video games.

By unanimous vote, a New York state court of appeals said the game’s depictions were “nothing more than cultural comment” and declared that Take-Two didn’t owe Lohan damages. Judge Eugene Fahey said the character in question, Lacey Jones, depicted a generic twenty-something woman that wasn’t specifically referencing the actress.

“We conclude that the amended complaint was properly dismissed because the artistic renderings are indistinct, satirical representations of the style, look, and persona of a modern, beach-going young woman that are not reasonably identifiable as plaintiff,” Fahey wrote in the court’s decision (PDF).

In a separate ruling (PDF), the court also dismissed similar claims against Take-Two from Karen Gravano, star of the reality TV show Mob Wives, who had alleged that her likeness had been used for another character.

US visa applications may soon require five years of social media info

The State Department wants to require all US visa applicants, both immigrant and non, disclose their social media handles to the US government, CNN reports. In documents that the department will file to the Federal Register tomorrow, it proposes that nearly every individual applying for a US visa be required to hand over any social media handles used on certain platforms in the past five years as well as submit any telephone numbers and email addresses used during that same time period.

Previously, this information was only requested from visa applicants who required more rigorous scrutiny — such as those who had traveled to regions with notable terrorist activity. But once enacted, these rule changes will require nearly all applicants submit this information, with the only potential exceptions being those applying for diplomatic and official visas. However, even they may have to provide their social media info, as the State Department’s documents only say “most” won’t be “routinely” asked for it.

Last year, the Department of Homeland Security introduced a new rule that allows social media information to be included in immigrants’ official records. But the move to incorporate social media handles and searches into visa application protocols precedes the Trump administration.

The State Department’s proposed changes also include questions about immigrants’ travel, whether they’ve been deported or removed from another country and if any of their relatives have been associated with terrorist activities. Applicants will also have the option to disclose social media handles used on platforms not listed on the questionnaire. Approximately 15 million visa applicants stand to be affected by the change.

Once the planned rule change is filed to the Federal Register on Friday, the public will have 60 days to comment on it.
