Apple: iPhones Are Too 'Complex' To Allow Unauthorized Repair

Slashdot - Sat, 23/09/2017 - 10:00am
Jason Koebler writes: Apple's top environmental officer made the company's most extensive statements about the repairability of Apple hardware on Tuesday: "Our first thought is, 'You don't need to repair this.' When you do, we want the repair to be fairly priced and accessible to you," Lisa Jackson, Apple's vice president of policy and social initiatives said at TechCrunch Disrupt in San Francisco. "To think about these very complex products and say the answer to all our problems is that you should have anybody to repair and have access to the parts is not looking at the whole problem." Apple has lobbied against "Fair Repair" bills in 11 states that would require the company to make its repair guides available and to sell replacement parts to the general public. Instead, it has focused on an "authorized service provider" model that allows the company to control the price and availability of repair.

Super-Accurate GPS Chips Coming To Smartphones In 2018

Slashdot - Sat, 23/09/2017 - 7:00am
schwit1 writes about a new mass-market Broadcom chip designed for the next generation of smartphones: It'll know where you are to within 30 centimeters (11.8 inches), rather than five meters. At least that's the claim chip maker Broadcom is making. It says that some of its next-generation smartphone chips will use new global positioning satellite signals to boost accuracy. In a detailed report on the announcement and how the new signals work, IEEE Spectrum says that the new chips, which are expected to appear in some phones as soon as next year, will also use half the power of today's chips and even work in cities where tower blocks often interfere with existing systems. All told, it sounds like a massive change for those who rely on their phones to find their way.

New Antibody Attacks 99% of HIV Strains

Slashdot - Sat, 23/09/2017 - 3:30am
An anonymous reader quotes a report from BBC: Scientists have engineered an antibody that attacks 99% of HIV strains and can prevent infection in primates. It is built to attack three critical parts of the virus -- making it harder for HIV to resist its effects. The work is a collaboration between the US National Institutes of Health and the pharmaceutical company Sanofi. Our bodies struggle to fight HIV because of the virus' incredible ability to mutate and change its appearance. These varieties of HIV -- or strains -- in a single patient are comparable to those of influenza during a worldwide flu season. So the immune system finds itself in a fight against an insurmountable number of strains of HIV. But after years of infection, a small number of patients develop powerful weapons called "broadly neutralizing antibodies" that attack something fundamental to HIV and can kill large swathes of HIV strains. Researchers have been trying to use broadly neutralizing antibodies as a way to treat HIV, or prevent infection in the first place. The study, published in the journal Science, combines three such antibodies into an even more powerful "tri-specific antibody." The experiments conducted on 24 monkeys showed none of those given the tri-specific antibody developed an infection when they were later injected with the virus. "We're getting 99% coverage, and getting coverage at very low concentrations of the antibody," said Dr Gary Nabel, the chief scientific officer at Sanofi and one of the report authors.

Artificial ‘skin’ gives robotic hand a sense of touch

Kurzweil AI - Sat, 23/09/2017 - 2:41am

University of Houston researchers have reported a development in stretchable electronics that can serve as artificial skin for a robotic hand and biomedical devices (credit: University of Houston)

A team of researchers from the University of Houston has reported a development in stretchable electronics that can serve as an artificial skin, allowing a robotic hand to sense the difference between hot and cold, and also offering advantages for a wide range of biomedical devices.

The work, reported in the open-access journal Science Advances, describes a new mechanism for producing stretchable electronics, a process that relies upon readily available materials and could be scaled up for commercial production.

Cunjiang Yu, Bill D. Cook Assistant Professor of mechanical engineering and lead author of the paper, said the work is the first to create a semiconductor in a rubber composite format, designed to allow the electronic components to retain functionality even after the material is stretched by 50 percent.

He noted that traditional semiconductors are brittle and using them in otherwise stretchable materials has required a complicated system of mechanical accommodations. That’s both more complex and less stable than the new discovery, as well as more expensive, he said. “Our strategy has advantages for simple fabrication, scalable manufacturing, high-density integration, large strain tolerance, and low cost,” he said.

The team used the skin to demonstrate that a robotic hand could sense the temperature of hot and iced water in a cup. The skin also was able to interpret computer signals sent to the hand and reproduce the signals as American Sign Language.

Uses of the stretchable skin include soft wearable electronics such as health monitors, medical implants, and human-machine interfaces.

The stretchable composite semiconductor was prepared by using a silicon-based polymer known as polydimethylsiloxane (PDMS) and tiny nanowires to create a solution that was then hardened into a material that used the nanowires to transport electric current.

Abstract of Rubbery electronics and sensors from intrinsically stretchable elastomeric composites of semiconductors and conductors

A general strategy to impart mechanical stretchability to stretchable electronics involves engineering materials into special architectures to accommodate or eliminate the mechanical strain in nonstretchable electronic materials while stretched. We introduce an all solution–processed type of electronics and sensors that are rubbery and intrinsically stretchable as an outcome from all the elastomeric materials in percolated composite formats with P3HT-NFs [poly(3-hexylthiophene-2,5-diyl) nanofibrils] and AuNP-AgNW (Au nanoparticles with conformally coated silver nanowires) in PDMS (polydimethylsiloxane). The fabricated thin-film transistors retain their electrical performances by more than 55% upon 50% stretching and exhibit one of the highest P3HT-based field-effect mobilities of 1.4 cm2/V∙s, owing to crystallinity improvement. Rubbery sensors, which include strain, pressure, and temperature sensors, show reliable sensing capabilities and are exploited as smart skins that enable gesture translation for sign language alphabet and haptic sensing for robotics to illustrate one of the applications of the sensors.

Hackers Using iCloud's Find My iPhone Feature To Remotely Lock Macs, Demand Ransom Payments

Slashdot - Sat, 23/09/2017 - 2:05am
AmiMoJo shares a report from Mac Rumors: Over the last day or two, several Mac users appear to have been locked out of their machines after hackers signed into their iCloud accounts and initiated a remote lock using Find My iPhone. With access to an iCloud user's username and password, Find My iPhone on iCloud.com can be used to "lock" a Mac with a passcode even with two-factor authentication turned on, and that's what's going on here. Affected users who have had their iCloud accounts hacked are receiving messages demanding money for the passcode to unlock a locked Mac device. The usernames and passwords of the iCloud accounts affected by this "hack" were likely found through various site data breaches and have not been acquired through a breach of Apple's servers. Impacted users likely used the same email addresses, account names, and passwords for multiple accounts, allowing people with malicious intent to figure out their iCloud details.

Court Rules That Imported Solar Panels Are Bad For US Manufacturing

Slashdot - Sat, 23/09/2017 - 1:25am
The International Trade Commission has ruled that American companies are being hurt by cheap solar panels from overseas, providing an opportunity for President Donald Trump to tax imports from countries like China. The Verge reports: Today's unanimous decision ruled that the companies SolarWorld Americans and Suniva were struggling financially not because of their own poor management, but because they couldn't compete with cheap panels from countries like China, Mexico, and South Korea. Suniva is now suggesting import duties of 40 cents a watt for solar cells, and a floor price of 78 cents a watt for panels. (Right now, the average floor price, worldwide, for panels is about 32 cents.) The Solar Energy Industries Association warned that implementing these suggestions could end up doubling the price of solar, thus destroying demand and causing Americans to lose their jobs.

A battery-free origami robot powered and controlled by external magnetic fields

Harvard University researchers have created a battery-free, folding robot “arm” with multiple “joints,” gripper “hand,” and actuator “muscles” — all powered and controlled wirelessly by an external resonant magnetic field.

The design is inspired by the traditional Japanese art of origami (used to transform a simple sheet of paper into complex, three-dimensional shapes through a specific pattern of folds, creases, and crimps). The prototype device is capable of complex, repeatable movements at millimeter to centimeter scales.

The research, by scientists at the Wyss Institute for Biologically Inspired Engineering and the John A. Paulson School of Engineering and Applied Sciences (SEAS), is reported in Science Robotics.

How it works

Design of small-scale-structure prototype of wirelessly controlled robotic arm (credit: Mustafa Boyvat et al./Science Robotics)

The researchers designed a 0.8-gram prototype small-scale-structure* prototype robotic “arm” capable of bending and opening or closing a gripper around an object. The “arm” is constructed with a special origami-like pattern that uses hinges (“joints”) to permit it to bend. There is also a “hand” (gripper — left panel in above image) that opens or closes.

To power the device, an external coil with its own power source (see video below) is used to generate a low-frequency magnetic field that induces an electrical current in three magnetic coils. The current heats the spiral-wire shape-memory-alloy actuator wires (coiled wire shown in inset above). That causes the actuator wires (“muscles”) to contract, making the attached nearby “joints” bend, and folding the robot body.

Mechanism of the origami gripper (for small-scale prototype design). (Left) The coil SMA actuator pushes the center link connected to both fingers and the gripper opens fingers, enabled by dynamic folding at the joints (left). The plate spring, which is a passive compression spring, pulls the link back as the gripper closes the fingers, again by rotations at folding joints (center). (Right) A photo of the gripper showing the SMA actuator wire attached at the center link. (credit: Mustafa Boyvat et al./Science Robotics)

By changing the resonant frequency of the external electromagnetic field, the two longer actuator wires (coiled wires shown in above illustration) are instead heated and stretched, opening the gripper (“hand”).

In both cases, when the external field-induced current stops, the actuators relax, springing back to their “memory” positions and causing the robot body to straighten out or the gripper’s outer triangles to close.

Minimally invasive medicine and surgery applications

As an example of a practical future application, instead of having an uncomfortable endoscope put down their throat to assist a doctor with surgery, a patient could just swallow a micro-robot that could move around and perform simple tasks, like holding tissue or filming, powered by a coil outside their body.

Using a much larger source coil — on the order of yards in diameter — could enable wireless, battery-free communication between multiple “smart” objects in a room or building.

“Medical devices today are commonly limited by the size of the batteries that power them, whereas these remotely powered origami robots can break through that size barrier and potentially offer entirely new, minimally invasive approaches for medicine and surgery in the future,” says Wyss Founding Director Donald Ingber, who is also the Judah Folkman Professor of Vascular Biology at Harvard Medical School and the Vascular Biology Program at Boston Children’s Hospital, as well as a Professor of Bioengineering at Harvard’s School of Engineering and Applied Sciences.

This work was supported by the National Science Foundation, the U.S. Army Research Laboratory, and the Swiss National Science Foundation.

* A large-scale-structure prototype version has minor differences, including 12-cm folding lines vs. 1.7-cm folding lines in the smaller version.

Abstract of Addressable wireless actuation for multijoint folding robots and devices

“Printing” robots and other complex devices through a process of origami-like folding is an emerging and promising manufacturing method due to the inherent simplicity and low cost of folding-based assembly. Folding is used in this class of device to create both complex static structures and flexure-based compliant mechanisms. Dependency on batteries to power these folds with no external wires is a hurdle to giving small-scale folding robots and devices functionality. We demonstrate a battery-free wireless folding method for dynamic multijoint structures, achieving addressable folding motions—both individual and collective folding—using only basic passive electronic components on the device. The method is based on electromagnetic power transmission and resonance selectivity for actuation of resistive shape memory alloy actuators without the need for physical connection or line of sight. We demonstrate the utility of this approach using two folded devices at different sizes using different circuit approaches.

Google Experiment Tests Top 5 Browsers, Finds Safari Riddled With Security Bugs

Slashdot - Sat, 23/09/2017 - 12:05am
An anonymous reader writes from a report via Bleeping Computer: The Project Zero team at Google has created a new tool for testing browser DOM engines and has unleashed it on today's top five browsers, finding most bugs in Apple's Safari. Results showed that Safari had by far the worst DOM engine, with 17 new bugs discovered after Fratric's test. Second was Edge with 6, then IE and Firefox with 4, and last was Chrome with only 2 new issues. The tests were carried out with a new fuzzing tool created by Google engineers named Domato, also open-sourced on GitHub. This is the third fuzzing tool Google creates and releases into open-source after OSS-Fuzz and syzkaller. Researchers focused on testing DOM engines for vulnerabilities because they expect them to be the next target for browser exploitation after Flash reaches end-of-life in 2020.

Verizon Backtracks Slightly In Plan To Kick Customers Off Network

Slashdot - Fri, 22/09/2017 - 11:20pm
An anonymous reader quotes a report from Ars Technica: Verizon Wireless is giving a reprieve to some rural customers who are scheduled to be booted off their service plans, but only in cases when customers have no other options for cellular service. Verizon recently notified 8,500 customers in 13 states that they will be disconnected on October 17 because they used roaming data on another network. But these customers weren't doing anything wrong -- they are being served by rural networks that were set up for the purpose of extending Verizon's reach into rural areas. Today, Verizon said it is extending the deadline to switch providers to December 1. The company is also letting some customers stay on the network -- although they must switch to a new service plan. "If there is no alternative provider in your area, you can switch to the S (2GB), M (4GB), 5GB single-line, or L (8GB) Verizon plan, but you must do so by December 1," Verizon said in a statement released today. These plans range from $35 to $70 a month, plus $20 "line fees" for each line. The 8,500 customers who received disconnection letters have a total of 19,000 lines. Verizon sells unlimited plans in most of the country but said only those limited options would be available to these customers. Verizon also reiterated its promise that first responders will be able to keep their Verizon service even though some public safety officials received disconnection notices. "We have become aware of a very small number of affected customers who may be using their personal phones in their roles as first responders and another small group who may not have another option for wireless service," Verizon said. "After listening to these folks, we are committed to resolving these issues in the best interest of the customers and their communities. We're committed to ensuring first responders in these areas keep their Verizon service."

Walmart Wants To Deliver Groceries Straight To Your Fridge

Slashdot - Fri, 22/09/2017 - 10:40pm
New submitter Rick Schumann writes: Walmart has a new marketing idea: "Going to the store? No one has time for that anymore," Walmart says. They want to partner with a company called August Home, who makes smart locks, so a delivery service can literally deliver groceries right into your refrigerator -- while you watch remotely on your phone. Great, time-saving idea, or super-creepy invasion of your privacy? You decide. Here's how the company says it would work: 1. Place an order on Walmart.com for groceries or other goods. 2. A driver for Deliv -- a same-day delivery service -- retrieves items when the order is ready, and brings them to the customer's home. 3. If no one answers, the delivery person can use a one-time passcode that's been pre-authorized by the customer to open the home's smart lock. 4. The customer receives a smartphone notification when the delivery is occurring, and can choose to watch it all play out in real-time on home security cameras through a dedicated app. 5. Delivery person leaves packages in the foyer, then brings the groceries to the kitchen, unloads them into the fridge, and leaves. 6. Customer receives notification that the door has locked behind them.

Adobe Security Team Accidentally Posts Private PGP Key On Blog

Slashdot - Fri, 22/09/2017 - 10:00pm
A member of Adobe's Product Security Incident Response Team (PSIRT) accidentally posted the PGP keys for PSIRT's email account -- both the public and the private keys. According to Ars Technica, "the keys have since been taken down, and a new public key has been posted in its stead." From the report: The faux pas was spotted at 1:49pm ET by security researcher Juho Nurminen. Nurminen was able to confirm that the key was associated with the psirt@adobe.com e-mail account. To be fair to Adobe, PGP security is harder than it should be. What obviously happened is that a PSIRT team member exported a text file from PSIRT's shared webmail account using Mailvelope, the Chrome and Firefox browser extension, to add to the team's blog. But instead of clicking on the "public" button, the person responsible clicked on "all" and exported both keys into a text file. Then, without realizing the error, the text file was cut/pasted directly to Adobe's PSIRT blog.

Passwords For 540,000 Car Tracking Devices Leaked Online

Slashdot - Fri, 22/09/2017 - 9:20pm
An anonymous reader quotes a report from The Hacker News: Login credentials of more than half a million records belonging to vehicle tracking device company SVR Tracking have leaked online, potentially exposing the personal data and vehicle details of drivers and businesses using its service. Just two days ago, Viacom was found exposing the keys to its kingdom on an unsecured Amazon S3 server, and this data breach is yet another example of storing sensitive data on a misconfigured cloud server. The Kromtech Security Center was first to discover a wide-open, public-facing misconfigured Amazon Web Server (AWS) S3 cloud storage bucket containing a cache belonging to SVR that was left publicly accessible for an unknown period. Stands for Stolen Vehicle Records, the SVR Tracking service allows its customers to track their vehicles in real time by attaching a physical tracking device to vehicles in a discreet location, so their customers can monitor and recover them in case their vehicles are stolen. The leaked cache contained details of roughly 540,000 SVR accounts, including email addresses and passwords, as well as users' vehicle data, like VIN (vehicle identification number), IMEI numbers of GPS devices. The leaked database also exposed 339 logs that contained photographs and data about vehicle status and maintenance records, along with a document with information on the 427 dealerships that use SVR's tracking services.
