Maglev Heart Could Keep Cardiac Patients Alive 49

Bivacor is working toward human trials of their artificial heart after the implant successfully kept a calf alive for 90-days, helping it stay healthy, energetic, and gain weight at a normal rate. It even jogged on a treadmill for 30-minute stretches. Artificial hearts have been discussed among cardiac surgeons and biomedical engineers for more than 50 years, but what makes Bivacor's artificial heart so unique is its use of a levitating disk, suspended in a magnetic field, that spins 2,000 times per minute to keep blood flowing. IEEE Spectrum reports: We had to overcome many technical challenges to make an artificial heart that's small, biocompatible, energy efficient, and durable. Consider that the human heart beats about 112,000 times a day, which adds up to 42 million times a year, and you'll understand the magnitude of the challenge. We've tested the Bivacor heart in 15 cows so far. While the need for animal testing is unfortunate, it's the only way to prove the device's safety and move forward to clinical trials in humans. These Corriente calves, which are relatively small, are the right size to serve as analogues for adult patients. We've also implanted the Bivacor heart in several sheep, which are more representative of patients with smaller bodies, including children. Our tests have shown that the heart holds up well: With its one moving part levitating in a magnetic field, there's no worry that friction and mechanical wear will cause the machine to give out. Our tests have also shown that the device can adapt to the user's cardiovascular requirements.

The Bivacor heart would fit in the palm of your hand -- it's about 650 grams, slightly heavier than an adult human heart. Its shell is made of titanium, a noncorroding material that almost never triggers an immune response. Patients will wear a 4-kg external controller pack that contains two rechargeable batteries (providing about 5 hours of operation each), although they can also plug in directly to a power outlet. Throughout our design process, we used 3D printers to make both titanium and plastic parts for our prototypes, allowing us to rapidly experiment with different geometries. For testing, we built a hardware simulation of the human circulatory system in our engineering office in Los Angeles; this mock-up allows us to validate a device's function thoroughly and repeatedly in a controlled environment, and reduces the need for animal testing.

Chicago Tribune Claims iPhone Radiofrequency Radiation Levels Measured Higher Than Legal Safety Limit In Tests (macrumors.com) 74

An anonymous reader quotes a report from MacRumors: The Chicago Tribune recently launched an investigation into the radiofrequency radiation levels output by popular smartphones, and found that some of Apple's iPhones are allegedly emitting radiofrequency radiation that exceeds safety limits. According to the newspaper, it contracted an accredited lab to test several smartphones according to federal guidelines. iPhones were secured below clear liquid formulated to simulate human tissue while probes measured the radiofrequency radiation the liquid absorbed.

Several iPhones measured over the legal safety limits in the tests, but the worst performer was the iPhone 7. Its radiofrequency radiation exposure was over the legal limit and more than double what Apple reported to federal regulators. The iPhone X was slightly over limits in some tests, as was the iPhone 8, while the 8 Plus stayed within the legal range. iPhones were tested twice after Apple provided feedback on the testing method. The modified test "added steps intended to activate sensors designed to reduce the phones' power." In these modified tests, where a reporter held the iPhone to activate the sensors in question, the iPhone 8 was under the 5mm limit, but the iPhone 7 models were not. Apple disputed the results found by The Chicago Tribune and said that the lab did not test the iPhones in the same way that Apple does, though Apple would not specify what was done wrong in the testing. Apple also said the modified testing had been done wrong.
The investigation also found smartphones from Samsung, Motorola, and Vivo also demonstrated radiofrequency radiation levels that exceed FCC guidelines. However, it's worth noting that testing was done in a way to simulate the worst possible exposure conditions.

The FCC said that it will be conducting its own tests over the next couple of months. "We take seriously any claims on non-compliance with the RF (radiofrequency) exposure standards and will be obtaining and testing the subject phones for compliance with FCC rules," agency spokesman Neil Grace said.

California High School In Silicon Valley Is Locking Up Students' Cellphones (nbcnews.com) 319

San Mateo High School administrators have instituted a new policy to lock up students' cellphones. "Each school day, nearly 1,700 students place their devices in a Yondr pouch that closes with a proprietary lock," reports NBC News. "School administrators unlock them at the end of the day." The goal is to help students focus on the teacher and other students. From the report: While administrators and teachers say they have already noticed a positive effect on students, the policy has elicited mixed reactions from researchers who argue its long-term effectiveness. Devices remain in the student's possession, but they aren't able to access them, the school said. The program was funded with a $20,000 grant. The pouches have been assigned to students at no cost, but losing one will cost the high-schoolers a $25 replacement fee.

Some technology experts feel the new policy is a step in the right direction and will curb distraction in the classroom. "Taking cellphones out of the classroom is a no-brainer," said Calvin Newport, a professor of computer science at Georgetown University. Students tend to perform worse when they have access to network connectivity in the classroom, he said. "The ability to be free of distraction and concentrate on things is increasingly valuable, so it's a good general function of our schools to be a place where our students get trained to keeping their concentration on one thing at a time," he added.

While many researchers have focused on the benefits of cutting out devices from the classroom, others worry about taking away something young people depend on. Larry Rosen, a research psychologist at California State University, said young people constantly check their phones to alleviate anxiety. They are anxious about staying on top of things, and that anxiety will build up if they are forced to ditch the devices cold turkey, he added. Taking away phones doesn't work for everyone, he argues. Instead, he believes "technology breaks" are a much happier medium.

Researchers Build a Heat Shield Just 10 Atoms Thick To Protect Electronic Devices (phys.org) 20

An anonymous reader quotes a report from Phys.Org: Excess heat given off by smartphones, laptops and other electronic devices can be annoying, but beyond that it contributes to malfunctions and, in extreme cases, can even cause lithium batteries to explode. To guard against such ills, engineers often insert glass, plastic or even layers of air as insulation to prevent heat-generating components like microprocessors from causing damage or discomforting users. Now, Stanford researchers have shown that a few layers of atomically thin materials, stacked like sheets of paper atop hot spots, can provide the same insulation as a sheet of glass 100 times thicker. In the near term, thinner heat shields will enable engineers to make electronic devices even more compact than those we have today, said Eric Pop, professor of electrical engineering and senior author of a paper published Aug. 16 in Science Advances. "To make nanoscale heat shields practical, the researchers will have to find some mass production technique to spray or otherwise deposit atom-thin layers of materials onto electronic components during manufacturing," adds Phys.Org.

"But behind the immediate goal of developing thinner insulators looms a larger ambition: Scientists hope to one day control the vibrational energy inside materials the way they now control electricity and light. As they come to understand the heat in solid objects as a form of sound, a new field of phononics is emerging, a name taken from the Greek root word behind telephone, phonograph and phonetics."

The Fashion Line Designed To Trick Surveillance Cameras (theguardian.com) 95

Freshly Exhumed shares a report from The Guardian: Automatic license plate readers, which use networked surveillance cameras and simple image recognition to track the movements of cars around a city, may have met their match, in the form of a T-shirt. Or a dress. Or a hoodie. The anti-surveillance garments were revealed at the DefCon cybersecurity conference in Las Vegas on Saturday by the hacker and fashion designer Kate Rose, who presented the inaugural collection of her Adversarial Fashion line.

To human eyes, Rose's fourth amendment T-shirt contains the words of the fourth amendment to the U.S. constitution in bold yellow letters. The amendment, which protects Americans from "unreasonable searches and seizures," has been an important defense against many forms of government surveillance: in 2012, for instance, the U.S. supreme court ruled that it prevented police departments from hiding GPS trackers on cars without a warrant. But to an automatic license plate reader (ALPR) system, the shirt is a collection of license plates, and they will get added to the license plate reader's database just like any others it sees. The intention is to make deploying that sort of surveillance less effective, more expensive, and harder to use without human oversight, in order to slow down the transition to what Rose calls "visual personally identifying data collection."
"It's a highly invasive mass surveillance system that invades every part of our lives, collecting thousands of plates a minute. But if it's able to be fooled by fabric, then maybe we shouldn't have a system that hangs things of great importance on it," she said.

Apple Confirms $1 Million Reward For Anyone Who Can Hack An iPhone (forbes.com) 65

Apple says it will offer up to $1 million for hackers who can find vulnerabilities in iPhones and Macs. "That's up from $200,000, and in the fall the program will be open to all researchers," reports Forbes. "Previously only those on the company's invite-only bug bounty program were eligible to receive rewards." From the report: As Forbes reported on Monday, Apple is also launching a Mac bug bounty, which was confirmed Thursday, but it's also extending it to watchOS and its Apple TV operating system. The announcements came in Las Vegas at the Black Hat conference, where Apple's head of security engineering Ivan Krstic gave a talk on iOS and macOS security. Forbes also revealed on Monday that Apple was to give bug bounty participants "developer devices" -- iPhones that let hackers dive further into iOS. They can, for instance, pause the processor to look at what's happening with data in memory. Krstic confirmed the iOS Security Research Device program would be by application only. It will arrive next year.

The full $1 million will go to researchers who can find a hack of the kernel -- the core of iOS -- with zero clicks required by the iPhone owner. Another $500,000 will be given to those who can find a "network attack requiring no user interaction." There's also a 50% bonus for hackers who can find weaknesses in software before it's released. Apple is increasing those rewards in the face of an increasingly profitable private market where hackers sell the same information to governments for vast sums.

Samsung's DeX On Note 10 Brings Phone Apps To Your PC (engadget.com) 32

Earlier today at Samsung's Galaxy Note 10 launch event, Samsung announced several new features coming to DeX, an application that transforms your Samsung phone into a "desktop like" interface. The expanded version of DeX on the Note 10 now works with your computer, allowing you to transfer files (including photos), reply to messages and run mobile apps on your Mac or Windows PC. Engadget reports: The Note 10 also touts a Link to Windows option in the phone's Quick Panel that connects to a Windows 10 PC, sharing your phone's notifications on your PC screen with no specialized apps required. This concept also isn't completely new, but it's still helpful if you'd rather not check your phone for a must-see message or app alert. More Microsoft integrations are coming. You'll get to make and receive calls right from your PC (it's not clear if this is just for Samsung phones or for all Android devices). Samsung's Gallery app, meanwhile, will tie into OneDrive to upload photos to cloud storage. If the company has its way, your phone and computer will feel like extensions of each other.

High-Security Locks For Government and Banks Hacked By Researcher (reuters.com) 46

pgmrdlm shares a report from Reuters: Hackers could crack open high-security electronic locks by monitoring their power, allowing thieves to steal cash in automated teller machines, narcotics in pharmacies and government secrets, according to research to be presented Friday at the annual Def Con hacking conference in Las Vegas. Mike Davis, a researcher with security firm IOActive, discovered the vulnerability last year and alerted government officials and Swiss company DormaKaba Holding, the distributor of multiple brands of locks at issue. In an interview with Reuters, Davis said he used an oscilloscope worth about $5,000 to detect small changes in the power consumption, through what is known as a side-channel attack. The method worked best in older models.

The locks include their own power supply so they function even when an external source of electricity is cut off. Most versions do not consume extra or randomized power to hide what they are doing. That leaves them open to attack if a thief can get physically close enough and has the right tools, Davis said. "I can download that analog signal and parse through the power trace to get ones and zeroes," Davis said. "I know what the lock is doing internally." Inside ATMs, the company's locks typically protect the cash in the more secure, lower compartment. An upper compartment includes the interface with customers and directs the lower compartment to send up money. The upper compartment often has less physical security, and breaking into it might provide access to the lower vault's vulnerable lock. A bigger concern is that another series of DormaKaba locks are used on military bases, U.S. presidential jet Air Force One and elsewhere in the government.

Microsoft Catches Russian State Hackers Using IoT Devices To Breach Networks (arstechnica.com) 99

An anonymous reader quotes a report from Ars Technica: Hackers working for the Russian government have been using printers, video decoders, and other so-called Internet-of-things devices as a beachhead to penetrate targeted computer networks, Microsoft officials warned on Monday. "These devices became points of ingress from which the actor established a presence on the network and continued looking for further access," officials with the Microsoft Threat Intelligence Center wrote in a post. "Once the actor had successfully established access to the network, a simple network scan to look for other insecure devices allowed them to discover and move across the network in search of higher-privileged accounts that would grant access to higher-value data."

Microsoft researchers discovered the attacks in April, when a voice-over-IP phone, an office printer, and a video decoder in multiple customer locations were communicating with servers belonging to "Strontium," a Russian government hacking group better known as Fancy Bear or APT28. In two cases, the passwords for the devices were the easily guessable default ones they shipped with. In the third instance, the device was running an old firmware version with a known vulnerability. While Microsoft officials concluded that Strontium was behind the attacks, they said they weren't able to determine what the group's ultimate objectives were.
Microsoft says they have notified the makers of the targeted IoT devices so they can add new protections. "Monday's report also provided IP addresses and scripts organizations can use to detect if they have also been targeted or infected," adds Ars Technica. "Beyond that, Monday's report reminded people that, despite Strontium's above-average hacking abilities, an IoT device is often all it needs to gain access to a targeted network."

Ask Slashdot: Budget-Friendly Webcam Without a Cloud Service? 118

simpz writes: Does anyone know of a fairly inexpensive webcam that doesn't depend on a cloud service? A few years ago, you could buy a cheap webcam (with the usual pan/tilt and IR) for about $50 that was fully manageable from a web browser. Nowadays the web interfaces are limited in functionality (or non-existent), or you need a phone app that doesn't work well (maybe only working through a cloud service). I've even seen a few cheap ones that still need ActiveX to view the video in a web browser, really people!

I'd like to avoid a cloud service for privacy and to allow this to operate on the LAN with no internet connection present. Even a webcam where you can disable the cloud connection outbound would be fine and allow you to use it fully locally. I guess the issue is this has become a niche thing that the ease of a cloud service connection probably wins for most people, and other considerations don't really matter to them.

I had a brief look at a Raspberry Pi solution, but didn't see anything like a small webcam form factor (with pan/tilt etc). Alternatively, are there any third-party firmwares for commercial webcams (sort of a OpenWRT-, DD-WRT-, or LineageOS-style project for webcams) that could provide direct local access only via a web browser (and things like RTSP)?

Cops Are Giving Amazon's Ring Your Real-Time 911 Caller Data (gizmodo.com) 54

Gizmodo has learned that Amazon's Ring home security system is pursuing contracts with police departments that would grant it direct access to real-time emergency dispatch data. From the report: The California-based company is seeking police departments' permission to tap into the computer-aided dispatch (CAD) feeds used to automate and improve decisions made by emergency dispatch personnel and cut down on police response times. Ring has requested access to the data streams so it can curate "crime news" posts for its "neighborhood watch" app, Neighbors. Ring says it does not provide the personal information of its customers to the authorities without consent. To wit, the company has positioned itself as an intermediary through which police requests access to citizen-captured surveillance footage. When police make a request, they don't know who receives it, Ring says, until a user chooses to share their video. Users are also prompted with the option to review their footage before turning it over.

But how often is one the victims of a crime in their own neighborhood? Likely not enough to stay engaged with the app for too long. Ring's solution is to push out alerts about alleged criminal activity reported nearby in real-time, according to company documents obtained by Gizmodo. Hiring people to monitor police scanners all day, however, is presumably too costly and inefficient. To pull off this trick, Ring needs something better: direct access to raw police dispatch data. Through its police partnerships, Ring has requested access to CAD, which includes information provided voluntarily by 911 callers, among other types of data automatically collected. CAD data is typically compromised of details such as names, phone numbers, addresses, medical conditions and potentially other types of personally identifiable information, including, in some instances, GPS coordinates.
Ring confirmed on Thursday that it does receive location information, including precise addresses from CAD data, which it does not publish to its app. It denied receiving other forms of personal information.

According to internal documents, police CAD data is received by Ring's "Neighbors News team" and is then reformatted before being posted on Neighbors in the form of an "alert" to users in the vicinity of the alleged incident. The document states that Ring's team only posts alerts for eight different crimes: burglary, vehicle break-in and theft, robbery, shots fired, shootings, stabbing, hostage, and arson.

Samsung Won't Let Android Tablets Die, Announces the Galaxy Tab S6 (arstechnica.com) 96

Samsung is one of the only companies still producing tablets to rival Apple's iPad. Today the company announced the Samsung Galaxy Tab S6, its latest high-end tablet, for $649. Pre-orders start August 23, and the device ships September 6. Samsung says there will be an LTE version available later. Ars Technica reports: The Samsung Tab S6 features a 10.5-inch 2560x1600 OLED display, a 2.84GHz Snapdragon 855, and a 7040mAh battery. The base version has 6GB of RAM and 128GB of storage, with a higher tier of 8GB of RAM and 256GB of storage. For cameras, there's an 8MP front camera, while the rear gets a 13MP main camera and a 5MP wide-angle lens. The device is down to 5.7mm thick and weighs 420 grams. This is Samsung's first-ever tablet with an in-screen fingerprint reader. Interestingly, it's an optical reader instead of the ultrasonic tech that the Galaxy S10 uses. Somehow, on a 10-inch tablet, Samsung couldn't find room for a headphone jack. Even Apple, which ditched the headphone jack two years ago, still puts a headphone jack on iPads. Samsung is apparently declaring war on the headphone jack with this round of updates -- the Galaxy Note 10, launching next week, is expected to dump the headphone jack, too.

The S-Pen comes with the tablet but doesn't stow away inside the body; instead, a groove on the back of the tablet gives it a spot to magnetically attach to. Of course, don't expect the tablet to sit flat on a table with a big pen attached to the back. As with other newer Samsung devices, the S-Pen now comes with a battery and some Bluetooth functionality, allowing it to do things like work as a remote shutter button for the camera. A new "Air action" gesture system lets you do things like change the camera mode or scroll through pictures with a flick of the pen.

The Hottest Phones For the Next Billion Users Aren't Smartphones (wsj.com) 95

Millions of first-time internet consumers from the Ivory Coast to India and Indonesia are connecting to the web on smart feature phones that cost only about $25. "[T]hese hybrid phones, fueled by inexpensive mobile data, provide some basic apps and internet access in addition to calling and texting," the Wall Street Journal reports. From the report: While global smartphone sales began sliding last year as markets became saturated, smart feature phone shipments tripled to around 75 million from 2017, according to research firm Counterpoint. Some 84 million are likely to be shipped this year. Even as rich nations start to roll out 5G technologies, some 3.4 billion people around the world remain cut off from the internet, according to We Are Social, another research firm. Most of them already use traditional, unconnected mobile phones, meaning they can easily make the transition to similarly shaped devices capable of high-speed web connections.

Smart feature phones aren't only inexpensive, but they also have physical keypads that are less intimidating than touch screens for those new to the technology. Meanwhile, their batteries last for days, a bonus in places where electricity is unreliable. There is a trade-off for the low price. The devices typically have slower and less powerful components, only basic cameras and their screens are usually just a few inches in size, factors that contribute to their longer battery life. There also are fewer apps available for smart feature phones.

How You Move Your Phone Can Reveal Insights Into Your Personality (sciencealert.com) 56

schwit1 shares a report from ScienceAlert: It may sound strange at first, but a team of researchers in Australia has come up with a method to predict your personality traits using just the accelerometer in your phone. Well, that and your call and messaging activity logs. Also, the system works for some traits better than others. But it's an interesting take on how we may find connections through such seemingly unrelated things. In this case, we start at the Big Five personality traits. These have been used in psychology since the 1980's to help classify five dominant parts of our personalities. These five traits are extraversion (outgoing vs reserved), openness (curious vs cautious), neuroticism (confidence vs nervous), agreeableness (compassionate vs detached) and conscientiousness (organised vs easy-going).

The researchers analysed 52 people's phone habits between March 2010 and July 2011. Each participant was given a phone with sensing and collection software on it, which gave the researchers information on when and how much the phone was moving (accelerometer data), as well as the number and time of day of all calls and messages. The participants were also asked to complete a Big Five survey to score their personalities on the five traits. Then, the team also created a list of features related to the aspects of phone use they measured, that might potentially determine personality traits; for example, physical activity on weekend nights might predict extraversion, or the number of calls one makes might predict agreeableness. After crunching the numbers, the researchers found that some of the phone features really did predict some of the personality traits for the 52 participants.
The phone data best predicted neuroticism, conscientiousness, and extraversion, but had trouble predicting the other two traits, especially openness. "There's also the issue of whether the team were actually looking at personality traits, or if the personality traits could be masked by other factors," the report adds. "For instance, neuroticism may be associated with different regularity of activity intensity in the night, however we cannot rule out many other possible explanations (e.g. neurotic people are more prone to stress and therefore - if this is the case, anyone with different personality traits that are stressed will still exhibit the same results)."

The study has been published in the journal Computer.

The Google Pixel 4 Will Have Built-In Radar and Unlock With a Face Scan (theverge.com) 72

In a YouTube video and blog post, Google revealed that its upcoming Pixel 4 smartphone will feature face unlock technology and a feature called "Motion Sense," which confirms that it will have a Project Soli chip that uses radar to detect hand gestures near the phone. The Verge reports: Adding face unlock puts the Pixel 4 on par with modern iPhones for unlocking, and it's (at least in theory) more convenient than an in-screen fingerprint sensor. Google also confirmed that the Pixel 4 will use the face unlock feature for payments: "face unlock works in almost any orientation -- even if you're holding it upside down -- and you can use it for secure payments and app authentication too." As with the iPhone, Google says that biometric data will be stored locally in a secure chip and never share with other Google services. The Pixel 4's face unlock feature will use a variety of sensors to identify your face, including depth, infrared, and RGB. That should mean that it will work in a variety of lighting situations and also work with a diverse set of faces. Google has told me that it has done "field research" to ensure both of those things.

As for the "Motion Sense" feature, there's not a ton that we can glean from Google's article. Earlier rumors have pointed to it being related to Project Soli, which uses radar to detect tiny hand or finger movements above the device. For example, Google has demoed rubbing your thumb and index finger together to simulate turning a dial on a smartwatch. Some code found in the next version of Android has suggested it could be used for media controls at the very least. Google's post cites a possible use case where the Soli chip could detect your hand reaching for the phone, which would automatically turn on "the face unlock sensors." If it all works, the phone would automatically unlock itself and be ready by the time you're looking at it.

200 Million Devices -- Some Mission-Critical -- Vulnerable To Remote Takeover (arstechnica.com) 46

An anonymous reader quotes a report from Ars Technica: About 200 million Internet-connected devices -- some that may be controlling elevators, medical equipment, and other mission-critical systems -- are vulnerable to attacks that give attackers complete control, researchers warned on Monday. In all, researchers with security firm Armis identified 11 vulnerabilities in various versions of VxWorks, a slimmed-down operating system that runs on more than 2 billion devices worldwide. Billed collectively as Urgent 11, the vulnerabilities consist of six remote code flaws and five less-severe issues that allow things like information leaks and denial-of-service attacks. None of the vulnerabilities affects the most recent version of VxWorks or any of the certified versions of the OS, including VxWorks 653 or VxWorks Cert Edition.

For the 200 million devices Armis estimated are running a version that's susceptible to a serious attack, however, the stakes may be high. Because many of the vulnerabilities reside in the networking stack known as IPnet, they can often be exploited by little more than boobytrapped packets sent from outside the Internet. Depending on the vulnerability, exploits may also be able to penetrate firewalls and other types of network defenses. The most dire scenarios are attacks that chain together multiple exploits that trigger the remote takeover of multiple devices. "Such vulnerabilities do not require any adaptations for the various devices using the network stack, making them exceptionally easy to spread," Armis researchers wrote in a technical overview. "In most operating systems, such fundamental vulnerabilities in the crucial networking stacks have become extinct, after years of scrutiny unravelled and mitigated such flaws."
VxWorks-maker Wind River says the latest release of VxWorks "is not affected by the vulnerability, nor are any of Wind Rivers' safety-critical products that are designed for safety certification, such as VxWorks 653 and VxWorks Cert Edition used in critical infrastructure."

Wind River issued patches last month and is in the process of notifying affected customers of the threat.

Samsung Galaxy Fold 'Ready' For Launch After Screen Fix (bbc.com) 80

Samsung said it has made the necessary improvements to fix the Galaxy Fold and put it back on sale. The April launch of the device was postponed after early reviewers reported broken screens; it's now scheduled to go on sale in September. From a report: "Samsung has taken the time to fully evaluate the product design, make necessary improvements and run rigorous tests," the company said in a statement. Improvements include extending a protective layer to make it clear it is not meant to be removed, as well as strengthening the hinge area with new protection caps. One explanation for the broken screens appears to have been that some reviewers removed a film which they thought was a typical protective layer that came with the phone when first bought.

MicroLED Displays Could Show Up In Products As Soon As 2020 (ieee.org) 50

An anonymous reader quotes a report IEEE Spectrum: One of the most striking things about the prototype microLED display that Silicon Valley startup Mojo Vision unveiled in June was its size. At half a millimeter across, it's barely bigger than a single pixel from the microLED TV prototype Samsung showed off in 2018. That both use versions of the same technology is remarkable, and it portends big potential for screens made of superefficient and bright micrometer-scale gallium nitride LEDs. Impressive prototypes have proliferated during the past year, and now that companies are turning to the hard work of scaling up their manufacturing processes, displays could appear in some products as soon as late next year. The driving force behind microLED displays remains a combination of brightness and efficiency that LCD and OLED technology can't come close to. One demo of a smartwatch-size display by Silicon Valley -- based Glo shines at 4,000 nits (candelas per square meter) while consuming less than 1 watt. An equivalent LCD display would burn out in seconds trying to meet half that brightness. Some companies "are making monolithic displays, where the gallium nitride pixels are made as a complete array on a chip and a separate silicon backplane controls those pixels," the report says. Others "are using 'pick and place' technology to transfer individual LEDs or multi-microLED pixels into place on a thin-film-transistor (TFT) backplane. The former is suited to microdisplays for applications like augmented reality and head-up displays. The latter is a better fit for larger displays."

Asus Unveils High-End 'ROG Phone II' Smartphone With 120Hz Display, Snapdragon 855 Plus, and Giant Battery (phonedog.com) 102

Asus has unveiled a spec-heavy gaming phone called the ROG Phone II. When it launches later this year, it'll be one of the only phones to feature Qualcomm's new gaming-focused Snapdragon 855 Plus processor, a 120Hz AMOLED display, and massive 6,000mAh battery. PhoneDog reports: The ROG Phone II features a 6.59-inch 2340x1080 AMOLED display with a 120Hz refresh rate and it's the first phone to include Qualcomm's gaming-focused Snapdragon 855 Plus processor. Both the CPU and GPU in the SD855 Plus are clocked higher than in the standard SD855, helping you get better performance. ASUS has crammed 12GB of RAM inside the ROG Phone II's body, too. Another gaming-centric feature of the ROG Phone II are its AirTrigger buttons. Located on the side of the device, they give you extra buttons for your games and an improved software algorithm over the first ROG Phone that lets you rest your fingers on the AirTriggers, meaning you can react more quickly since you're not having to move your fingers to reach for the buttons.

Other notable features of the ROG Phone II include a 48MP main camera with Sony IMX586 sensor, a 13MP ultra wide rear camera with a 125-degree field of view, and a 24MP front camera. There's up to 512GB of built-in storage available, an in-display fingerprint reader, dual front-facing speakers, and a 3.5mm headphone jack. Powering the whole package is a whopping 6000mAh battery. There are two USB-C ports on the ROG Phone II, with one in a traditional place on the bottom of the device and the other on the side of the phone so that it doesn't get in your way when you're gaming and charging. Both ports support Quick Charge 3.0, but the side port can charge more quickly with QuickCharge 4.0 support. It also includes support for 4K video output using DisplayPort 1.4.
We don't have an official price or release date yet, but it's likely to start shipping later this year at around $899, which was the cost of the original ROG Phone.

Apple In Advanced Talks To Buy Intel's Smartphone-Modem Chip Business (cnbc.com) 64

According to The Wall Street Journal, Apple is in advanced talks to buy Intel's smartphone-modem chip business (Warning: source paywalled; alternative source), "a move that would jump-start the iPhone maker's push to take control of developing the critical components powering its devices." From the report: A deal, covering a portfolio of patents and staff valued at $1 billion or more, could be reached in the next week, the people said -- assuming the talks don't fall apart. Though the purchase price is a rounding error for companies valued in the hundreds of billions of dollars, the transaction would be important strategically and financially. It would give Apple access to engineering work and talent behind Intel's yearslong push to develop modem chips for the crucial next generation of wireless technology known as 5G, potentially saving years of development work.

For Intel's part, a deal would allow the company to shed a business that had been weighing on its bottom line: The smartphone operation had been losing about $1 billion annually, a person familiar with its performance has said, and has generally failed to live up to expectations. Though it would exit the smartphone business, Intel plans to continue to work on 5G technology for other connected devices.
Earlier this year, it was reported that Apple began discussing plans to acquire parts of Intel's smartphone modem chip business last summer, around the time former Intel Chief Executive Brian Krzanich resigned. "Mr. Krzanich championed the modem business and touted 5G technology as a big future revenue stream," reports The Wall Street Journal. "When Bob Swan was named to that job in January, analysts said the odds of a deal rose because his focus on cleaning up Intel would require addressing the losses in the modem business."
