MIT’s thread-like robot can slip through blood vessels in your brain

[ad_1]

The team described the “magnetically steerable, hydrogel-coated robotic thread” in a paper published in Science Robotics. The core of the thread is made from nickel-titanium alloy, which is both bendy and springy. It’s coated with a rubbery paste, or ink, which is embedded with magnetic particles. That’s then covered with a hydrogel, which makes the wire smooth and friction-free, and the final product can be controlled using magnets.

Today, surgeons typically clear blood clots in the brain by inserting a thin wire through a person’s main artery. The surgeons use a fluoroscope, which images the blood vessel using X-rays, to manually rotate and guide the wire into the damaged brain vessel. A catheter is then threaded along the wire to deliver drugs or other clot therapies. But the procedure is physically taxing on the surgeons, who are exposed to repeated radiation from the fluoroscope. And the wires carry the risk of damaging the vessel linings.

In contrast, this robotic thread is controlled by magnets, and surgeons could guide it from outside of the operating room. They’d be protected from repeated radiation exposure, and they might be able to perform procedures remotely using a joystick. Yes, remote robotic brain surgery using a joystick.

Thanks to the hydrogel, there’s less risk of friction against the vessel linings, and the device could help surgeons reach even further into the brain. “One of the challenges in surgery has been to be able to navigate through complicated blood vessels in the brain, which has a very small diameter, where commercial catheters can’t reach,” said Kyujin Cho, professor of mechanical engineering at Seoul National University. “This research has shown potential to overcome this challenge and enable surgical procedures in the brain without open surgery.”

The robotic thread isn’t ready for clinical use, but the team demonstrated its agility by steering the thread through an obstacle course of small rings, similar to threading a needle. They also created a life-sized replica of the brain’s major blood vessels and guided the robot through those winding, narrow paths. Eventually, they hope the robotic wire might deliver clot-reducing drugs or break up blockages with a laser.

Google’s bug bounty program now covers all popular Android apps

[ad_1]

Google’s expanded initiative, called the Google Play Security Reward Program, offers rewards to developers who uncover issues in apps on the Play Store. Previously, the program only covered a set list of eight top apps, but now any app from the Play Store with more than 100 million installs is fair game. If developers discover and disclose a vulnerability in an app to Google, they can claim bounties of up to $30,000.

Typical bug bounty programs are run by companies to offer rewards to people who find security issues within the company’s own software. This program is unusual in that it offers bounties for finding vulnerabilities in other company’s apps as well.

This opens the door for security researchers to help hundreds of organizations identify and fix vulnerabilities in their apps,” a Google spokesperson said. If an app developer has its own bug bounty program, bugs can be claimed from both the app developers and Google.

In addition, Google is launching a Developer Data Protection Reward Program to hunt down “data abuse issues” in Android apps, OAuth projects and Chrome extensions. This means findings apps which are using or selling users’ data without user consent. If a data abusing app or extension is reported to the program, it will be removed from the Play Store or the Chrome Web Store and the bug hunter will receive a payment of up to $50,000.

Juul will require retailers to scan IDs before selling its vapes

[ad_1]

These new Retail Access Control Standards (RACS) are Juul’s latest attempt to curb teen vaping. More than 50 retail chains — a total of more than 40,000 outlets — have agreed to comply. Juul will stop distributing products to retailers who aren’t RACS-certified by May 2021. And because the company recognizes that updating POS systems is no small task, it’s offering more than $100 million in incentives and financial support to retailers looking to implement the new system.

Juul is also expanding its track-and-trace program. That allows educators, law enforcement and parents to enter a Juul serial number into an online portal to see where the device was purchased. It was introduced as an experiment this spring, and it will now be rolled out nationwide.

Juul claims its target market is the one billion existing adult smokers globally, but the FDA has accused it of undermining efforts to prevent teen vaping. It’s also under investigation by both the House and Senate. The new POS rules could help Juul stave off more regulations and lawsuits — like the one filed recently by North Carolina. Though RACS would do little to prevent teens from buying the products online — an issue San Francisco is grappling with.

According to the FDA, in 2018, more than 3.6 million middle and high school students across the US were current e-cigarette users. The CDC has identified at least 193 cases of severe lung illnesses, which are potentially linked to vaping.

Tech tools to keep you safe

[ad_1]

“The self-defense seminars that I teach are all weapons-based,” White said. “Because I do believe, even after all this time doing martial arts, that the empty-hands stuff, it’s effective but it takes time to distill. And it’s not always going to work out for you on the street. I always promote somebody leveling the playing field by getting something in their hand.”

White’s doorstop advice isn’t a suggestion to bring down assailants by smacking them with rubber wedges. It’s about prevention, and it’s proof that your self-defense tools don’t need to be high-tech to get the job done (though a little electricity certainly helps).

We asked White to break down the best gadgets to have in your bag, pocket or hand when walking alone down a dark alley, and he had plenty of suggestions. He also had a story for every situation.

S-s-s-state-breaker

One night years ago, White found himself in a teachable moment.

“I broke up a fight,” he said. “It was a melee, really. It was about 30 people. It was bikers and punk rock kids. It was back in the day.”

Instead of diving in, fists flailing, White wanted to defuse the situation with whatever he had on hand. In this case, it was a bamboo fan.

“One of the weapons we use in Chinese kung fu is a fan,” he said, “and people don’t realize when you really pop it open, it’s loud. It’s really close to the sound of a gunshot.”

So, White pulled out his fan and made his move.

“These guys were pounding the shit out of each other,” he said. “And when you take the fan and pop it, you go like pop-pop-pop-pop-pop five times quick, what actually occurs there mentally is it’s a state-breaker. And that’s what happened. Every single person just stopped. They were still holding each other mid-punch and just looked, and everyone went from anger to what the?”

basu

State-breakers come in myriad forms, from jarring sounds to bright lights, but they essentially cover anything that shocks an attacker into temporary confusion, pausing the assault and providing a window to escape or fight back. White doesn’t recommend everyday folks carry fans in their back pockets, but there are plenty of tools on the market designed with state-breaking in mind. For instance, there’s the BASU eAlarm+ ($25), a gadget that emits a loud sound when the top pin is pulled. It looks like a USB device and it’s small enough to fit on a keychain, but when activated it emits an alarm at 130 decibels, a noise level comparable with standing 50 feet away from a military jet, complete with afterburner, as it takes off from an aircraft carrier.

“It’s not so much the gadget as what the application is,” White said. “Like the flashlight, just blinding somebody with a flashlight for a second is a state-breaker.”

A flashlight is one of White’s go-to personal defense tools. Not only can one temporarily blind someone, but many are heavy and sturdy enough to also be used in a physical altercation.

“A really good flashlight, it’s not obvious, but when you look on the end of the bezel, which is where the light comes out, they have these crenellated striking edges on them,” White said. “And they’re so underrated as a self-defense tool because you can hit with it, but you don’t even really have to. You can press it into somebody’s clavicle and they’ll just wilt under it.”

Some flashlights are built specifically for self-defense purposes, with exaggerated bezels and textured grips. The SureFire Defender Ultra ($179) is an LED tactical light designed for fighting, with an aluminum body and Mil-Spec hard-anodized coating. It’s small enough to fit in a pocket and strike with one hand. It’s also a powerful flashlight, of course.

“Obviously with a flashlight you can blind them, but in general just illuminating your path and seeing what you’re coming up against — it’s just good practice to have a flashlight,” White said.

Stunna tech

The Venn diagram of “tech gadgets” and “self-defense weapons” has one giant, all-caps word at the heart of its intersection: TASER.

“I can only recommend what I know is going to work for people, and when it comes to using self-defense tools, the obvious one when it comes to tech, to me, is the taser,” White said, “which is a great option.”

He took a few seconds to talk through that last statement before adding, “Where they are allowed, a taser is a good option.”

taser

Tasers may be the ultimate self-defense tool, but they come with a handful of limitations. First, here’s how they work: Pulling the trigger expels two tiny electrified probes that stay connected to the weapon via conductive wire measuring up to 15 feet in commercial models. The darts in newer iterations are designed to puncture thick layers of clothing and stay embedded in the skin once they make contact, firing electrical pulses into a person and resulting in neuromuscular incapacitation — the loss of control of their muscles.

Tasers are high-reward and also high-risk. They’re effective when wielded properly, but they can be extremely dangerous, even lethal, for anyone who hasn’t studied up and practiced using one. Tasers are more expensive than many other self-defense tools, and they’re not legal for civilian use in every state.

But if you can get a taser and invest time in training, it’s the number one option for personal self-defense. The Pulse+ ($450) is the latest model from TASER, the company and proprietary eponym. It’s equipped to work in the Information Age — the Pulse+ pairs with the Noonlight app, which can alert authorities the second your weapon is fired, using your phone’s GPS to track your location. That service costs $9.99 a month.

“There’s a lot of training involved,” White said. “They’re not cheap. But that’s kind of the ultimate, I would say, gadget. …I teach more locally in the northeast, and again, it’s just not an option because you can’t carry one.”

Which brings us to the final scenario: weapons you can bring nearly anywhere.

Writing and wet-weather weaponry

White’s next recommendation sounds like something out of Spy Kids.

“When I travel internationally,” he said, “I usually have what’s called an Unbreakable Umbrella.”

Unbreakable Umbrellas come from NTOI, and the walking-stick model that White favors runs $129.95. On top of functioning as a perfectly fine umbrella, an Unbreakable is light, weighing just over one pound. It still “whacks just as strong as a steel pipe,” according to NTOI, and it’s legal to carry everywhere.

ntoi

“It’s really cool,” White said. “Just a super sturdy umbrella with a metal rod all the way down the center, and it’s got a crook on it like a cane does. And, because it’s an umbrella, it really comes in under the radar.”

Another everyday item that works well as a defense tool is the tactical pen. This one is a little trickier, when it comes to airplanes — the Transportation Security Administration considers tactical pens to be weapons, and therefore they’re banned from flights. However, many models are sleek enough that they simply look like high-quality or extra-rugged writing devices, meaning they can be carried into most scenarios without raising alarm.

Take the ISBOSI Tactical Pen ($39.95), for example. It’s a large, stainless-steel device with a knob on the back and an extra-long, extra-pointy tip, but it’s still immediately recognizable as a pen, not a weapon.

Proper training

An unspoken refrain runs beneath all of White’s advice: Practice. Practice. Practice. He teaches self-defense classes and highly recommends them to anyone curious about personal-security gadgets. Even with all of the fighting and defense styles at a student’s disposal, White said some of the most powerful moments in his lessons aren’t physical at all. They occur when a student actually gets their hands on a tool, and suddenly recognizes their personal limits of violence and security.

“These tech items are part of the recommended self-defense spectrum,” White said. “I teach all those different things because I understand that choosing to carry a weapon is a very personal thing for somebody. Not everybody is willing to grab a blade and cut somebody — nor should they. And vice versa with firearms and any weapons. So it’s really a bit of discovery you have to go on internally to decide what’s good with you morally.”

There’s absolutely nothing wrong, morally or otherwise, with buying a new umbrella. And if you’re going to buy a new umbrella, you might as well get the one with a metal rod running down the center for protection from the rain and anything else.

Apple will ‘verify’ third-party iPhone repair stores

[ad_1]

Apple COO Jeff Williams says that the move will enable small mom-and-pop repair outfits to get the same tools and gear as authorized repair stores. And that it’ll help improve confidence that users are getting a trustworthy service without going to an official Apple store, or one of their proxies. For now, the program is limited to “out of warranty iPhone repairs,” so your broken iPad may still need to be sent back to Apple.

The program is free to join, as long as businesses employs an “Apple-certified” technician, although certification is also, apparently, free. Apparently, the company has been running a quiet pilot with a handful of indie stores across the world, who are receiving genuine parts for use. And Apple says that third-parties can source parts and tools for the same price as current Authorized Service Providers.

Earlier this year, Apple also said that it was working with Best Buy to ensure that Geek Squad, the retailer’s support arm, will be able to offer same-day repairs. This is likely also a reflection of the spike in people opting to replace their phone batteries when Apple cut the price to $29 in the wake of throttlegate. During the discount period, 11 million people paid for a replacement, up from the usual two million.

Expanding the repair program is a long-overdue move after Apple received significant criticism about how it handles iPhone repairs. The company has sought to frustrate third-party repair programs by making iPhones less functional after they’ve been fixed. That included a warning if you use a stock replacement battery and, in come cases, breaking even genuine replacement displays and TouchID replacements.

Because Apple has often talked-up its green credentials, the fact it wouldn’t allow basic iPhone repairs smacked of hypocrisy. After all, replacing the battery of an otherwise perfectly-serviceable iPhone 7 is better for the planet than buying a new iPhone XR. The fact that Apple also charged a significant premium for these basic repairs raised hackles for the same reasons.

Relaxing this policy and allowing third-parties to fix common iPhone issues is a good start, especially if it results in lower prices and longer-lasting devices. It’ll be interesting to see if other Apple hardware, like its laptops and tablets, get added to the program in future. Especially given the contentious battles between the company and right-to-repair advocates like Louis Rossmann.

Spotify is testing a ‘Create podcast’ button inside its app

[ad_1]

The feature was uncovered by app researcher Jane Manchun Wong, who reverse-engineers apps to dig up preview features. She has a record of scooping new technology features, so it’s a pretty reliable finding.

The Anchor podcast creation app, recently purchased by Spotify, has an upcoming promo page about the feature too. Spotify bought Anchor at the same time it purchased podcast studio Gimlet Media, creators of the popular Reply All internet culture podcast.

Spotify has been pushing podcast content since it made these acquisitions, including promoting its own podcast exclusives like the sport-focused Riggle’s Picks. This feature will encourage users interested in creating their own podcasts to try the Anchor app as well.

With an audience of 180 million active users, getting on Spotify gives podcasters the opportunity to reach a potentially massive audience. However, with so many podcasts available — Google announced it had indexed over 2 million podcasts last year — trying to attract listeners in the crowded market will be a challenge.

Garmin’s new Fenix 6 watches are prettier and last longer

[ad_1]

There’s also a new PacePro feature that will coach you in real time so you can speed up or slow down during your run rather than try to remember what to do the next time you work out. As you jog, the Fenix 6 will show your target split pace, actual split pace, distance to next split and how much time you’re ahead of or behind your goal. It’ll also take into account your elevation grade and adjust your targets accordingly.

Garmin is also adding maps from ski resorts worldwide that you can download to your watch from the companion app for free. The existing maps for golf courses will also be upgraded to full color and will now show you the distance to the front, middle and back of each hole.

In addition to all the updates, the Fenix 6 series will come with features its predecessors already packed. You’ll get Garmin Pay for contactless payments, the company’s powerful fitness-tracking tools, smartphone alerts on your wrist and Amazon Music support (along with Spotify, Deezer and iHeartRadio).

Compared to their predecessors, the Fenix 6 and 6X have larger 1.3-inch and 1.4-inch faces respectively, while retaining the same size as before. All three new models will have the Pulse Ox bloody oxygen sensor whereas it was only available on the most expensive Plus model on the Fenix 5. The new Fenix range starts at $599, with pricing changing depending on the finishes and straps you pick. It’s nice to see Garmin roll out a more comprehensive set of styles for a line of watches that has traditionally looked bulky and masculine. With the new designs and features, the Fenix 6 lineup looks like a compelling watch for those considering a serious, yet stylish GPS watch.

NASA’s much-delayed James Web Space Telescope has finally been assembled

[ad_1]

The telescope will be the successor to Hubble, and it includes a five-layer sunshield which blocks infrared light from the sun to keep the delicate components cool. The sunshield was already integrated with the spacecraft that will launch the project, and the telescope itself had to be lifted onto to this combination using a crane. Engineers aligned and secured the two halves together to complete the mechanical connection.

Next, the engineers must electrically connect the two halves and test the electrical connections before unfurling the sunshield and performing environmental and deployment testing.

“This is an exciting time to now see all Webb’s parts finally joined together into a single observatory for the very first time,” said Gregory Robinson, the Webb program director at NASA Headquarters. “The engineering team has accomplished a huge step forward and soon we will be able to see incredible new views of our amazing universe.”

Launch is scheduled for 2021, when the telescope will investigate celestial bodies from our solar system but also those in distant galaxies.

YouTube Kids is getting its own website

[ad_1]

The Google-owned video platform has been under intense scrutiny over the past few years due to various issues related to videos targeting children. It had to grapple with the rise in child-exploitative videos that masqueraded as family-friendly content, and it even had to shut down the comments section in videos with young children, because they were plagued with pedophilic responses. The platform also had to face an FTC probe that looked into whether it violated COPPA by collecting data for children under the age of 13.

In addition to launching a dedicated website for children, the platform has also introduced new categories for YouTube Kids, so young users can explore videos in a safer environment. You’ll now be able to control what the app shows by choosing from three different age groups: Preschool for kids ages 4 and under, Younger for children ages 5 to 7 and Older for kids ages 8 to 12. The Older category can show a wider variety of videos, of course, including music and gaming videos, as well as family vlogs.

Despite the new measures, YouTube has included a reminder in its announcement that it doesn’t manually review all its videos. “Our systems work hard to exclude content not suitable for each of these age categories, but not all videos have been manually reviewed,” it wrote. It’s worth noting that YouTube’s algorithms are nowhere near perfect, as Wired found in 2018 when it discovered the bizarre and disturbing content that popped up while searching for children’s search terms.

Microsoft HoloLens 2 will go on sale in September

[ad_1]

The tech giant’s upcoming headset promises a more comfortable experience than its predecessor. We were able to confirm just how comfortable the headset is — it felt more balanced and less hot — when we tested it out at MWC. The device was also designed to be more immersive. It has double the field of view of its predecessor, which Microsoft says is like switching from a 720p television to a 2K set for each eye, and has retina-tracking capabilities. As you can imagine, the headset won’t come cheap: it has a $3,500 price tag, which isn’t really surprising, seeing as its target audiences are enterprise users and institutions.
