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 Read more about Researchers build a heat shield just 10 atoms thick to protect electronic devices[…]

By activating a dormant software lock on their newest iPhones, Apple is effectively announcing a drastic new policy: only Apple batteries can go in iPhones, and only they can install them. If you replace the battery in the newest iPhones, a message indicating you need to service your battery appears in Settings > Battery, next Read more about Apple Is Locking iPhone Batteries to Discourage Repair, showing ominous errors if you replace your battery[…]

Contemporary science, medicine, engineering and information technology demand efficient processing of data—still images, sound and radio signals, as well as information coming from different sensors and cameras. Since the 1970s, this has been achieved by means of the Fast Fourier Transform algorithm (FFT). The FFT makes it possible to efficiently compress and transmit data, store Read more about Quantum interference allows huge data sets to be sifted through much more quickly[…]

On newer Linux distributions, there’s a hard regression either within the kernel but more likely some cross-kernel/user-space interaction issue leaving newer Linux distributions unbootable. While Ubuntu 18.04 LTS and older Linux distributions boot Zen 2, to date I have not been able to successfully boot the likes of Ubuntu 19.04, Manjaro Linux, and Fedora Workstation Read more about AMD Ryzen 7 3700X + Ryzen 9 3900X Offer Incredible Linux Performance – if you can get it to boot. Which newer distros seemingly can’t[…]

The ZenBook Pro Duo has not one, but two 4K screens. (At least if you’re counting horizontal pixels.) There’s a 15-inch 16:9 OLED panel where you’d normally find the display on a laptop, then a 32:9 IPS “ScreenPad Plus” screen directly above the keyboard that’s the same width and half the height. It’s as if Read more about The Asus ZenBook Pro Duo laptop with two 4K screens – for some reason people are comparing to Apples touch bar, but has nothing to do with that.[…]

A person’s “right to repair” their own equipment may well become a US election issue, with presidential candidate Bernie Sanders making it a main talking point during his tour of Iowa. “Are you ready for something truly insane?” the veteran politician’s account tweeted on Sunday, “Farmers aren’t allowed to repair their own tractors without paying Read more about Tractors, not phones, will (maybe) get America a right-to-repair law at this rate: Bernie slams ‘truly insane’ situation[…]

Aweigh is an open navigation system that does not rely on satellites: it is inspired by the mapping of celestial bodies and the polarized vision of insects. Ancient seafarers and desert ants alike use universally accessible skylight to organize, orient, and place themselves in the world. Aweigh is a project that learns from the past Read more about Aweigh – open source navigation system without satellites[…]

In February, the company announced its intention to move forward with the development of the Curie cable, a new undersea line stretching from California to Chile. It will be the first private intercontinental cable ever built by a major non-telecom company. And if you step back and just look at intracontinental cables, Google has fully financed Read more about Google and other tech giants are quietly buying up the most important part of the internet[…]

Researchers at the Black Hat Asia conference this week disclosed a previously unknown way to tap into the inner workings of Intel’s chip hardware. The duo of Mark Ermolov and Maxim Goryachy from Positive Technologies explained how a secret Chipzilla system known as Visualization of Internal Signals Architecture (VISA) allows folks to peek inside the Read more about The hidden backdoor in Intel processors is a fascinating debug port (you have to pwner to use it anyway)[…]

Canadian startup D-Wave Systems has extended the availability of its Leap branded cloud-based quantum computing service to Europe and Japan. With Leap, researchers will be granted free access to a live D-Wave 2000Q machine with – it is claimed – 2,000 quantum bits, or qubits. Developers will also be free to use the company’s Quantum Read more about Europe, Japan: D-Wave would really like you to play with its ‘2,000-qubit’ quantum Leap cloud service[…]

Microsoft has helped build the first device that automatically encodes digital information into DNA and back to bits again. DNA storage: Microsoft has been working toward a photocopier-size device that would replace data centers by storing files, movies, and documents in DNA strands, which can pack in information at mind-boggling density. According to Microsoft, all Read more about Microsoft just booted up the first “DNA drive” for storing data[…]

Scientists from Heriot-Watt University have welded glass and metal together using an ultrafast laser system, in a breakthrough for the manufacturing industry. Various optical materials such as quartz, borosilicate glass and even sapphire were all successfully welded to metals like aluminium, titanium and stainless steel using the Heriot-Watt laser system, which provides very short, picosecond Read more about Welding glass to metal breakthrough could transform manufacturing[…]

A team of Cambridge researchers have found a way to control the sea of nuclei in semiconductor quantum dots so they can operate as a quantum memory device. Quantum dots are crystals made up of thousands of atoms, and each of these atoms interacts magnetically with the trapped electron. If left alone to its own Read more about Physicists get thousands of semiconductor nuclei to do ‘quantum dances’ in unison[…]
