Stanford University scientists experimenting with a decades-old, single-use battery architecture have developed of a new version that is not only rechargeable, but offers around six times the capacity of today’s lithium-ion solutions. The breakthrough hinges on the stabilization of volatile chlorine reactions within the device, and could one day provide the basis for high-performance batteries that power smartphones for a week at a time.

The new battery is described as an alkali metal-chlorine battery, and is based on chemistry that first emerged in the 1970s called lithium-thionyl chloride. These batteries are highly regarded for their high energy density, but rely on highly reactive chlorine that makes them unsuitable for anything other than a single use.

In a regular rechargeable battery, the electrons travel from one side to the other during discharging and then are reverted back to their original form as the battery is recharged. In this case, however, the sodium chloride or lithium chloride is converted to chlorine, which is too reactive to be converted back to chloride with any great efficiency.

A Tesla semi-truck with a very Tesla-worthy aesthetics highlighted by the contoured yet sharp design language that in a way reminds me of the iPhone 12!

Tesla’s visionary Semi all-electric truck powered by four independent motors on the rear is scheduled for production in 2022. The semi is touted to be the safest, most comfortable truck with an acceleration of 0–60 mph in just 20 seconds and a range of 300–500 miles. While the prototype version looks absolutely badass, how the final version will look is anybody’s guess.

“We are thinking about volumes in millions.”

“We are thinking about volumes in millions, not the thousands that people talk about with quantum computers based on superconducting,” said Marcus Doherty, chief science officer.

Quantum Brilliance delivered its first system to the Pawsey Supercomputing Centre in Australia earlier this year and is beginning to ship to other commercial customers.

The ‘Joker’ virus hides in several apps on the Google Play Store and the user does not realize it until their bank accounts are emptied. See how this malware operates and what are the dangerous applications.

In September 2,020 the ’Joker’ virus was found in 24 Android applications that registered more than 500 thousand downloads before being removed. It is estimated that that time it affected more than 30 countries including the United States, Brazil and Spain. Through unauthorized subscriptions, hackers could steal up to $7 (about 140 Mexican pesos) per subscription weekly, a figure that has most likely increased in recent months.

How does the Joker virus work in Android apps?

Summary: Retrofitting wireless earbuds to detect neural signals and relaying the data back to smartphones via Bluetooth, researchers say the new earEEG system could have multiple applications, including health monitoring.

From keypads to touch screens to voice commands – step by step, the interface between users and their smartphones has become more personalized, more seamless. Now the ultimate personalized interface is approaching: issuing smartphone commands with your brain waves.

Artificial intelligence (AI) will fundamentally change medicine and healthcare: Diagnostic patient data, e.g. from ECG, EEG or X-ray images, can be analyzed with the help of machine learning, so that diseases can be detected at a very early stage based on subtle changes. However, implanting AI within the human body is still a major technical challenge. TU Dresden scientists at the Chair of Optoelectronics have now succeeded for the first time in developing a bio-compatible implantable AI platform that classifies in real time healthy and pathological patterns in biological signals such as heartbeats. It detects pathological changes even without medical supervision. The research results have now been published in the journal Science Advances.

In this work, the research team led by Prof. Karl Leo, Dr. Hans Kleemann and Matteo Cucchi demonstrates an approach for real-time classification of healthy and diseased bio-signals based on a biocompatible AI chip. They used polymer-based fiber networks that structurally resemble the human brain and enable the neuromorphic AI principle of reservoir computing. The random arrangement of polymer fibers forms a so-called “recurrent network,” which allows it to process data, analogous to the human brain. The nonlinearity of these networks enables to amplify even the smallest signal changes, which—in the case of the heartbeat, for example—are often difficult for doctors to evaluate. However, the nonlinear transformation using the polymer network makes this possible without any problems.

In trials, the AI was able to differentiate between healthy heartbeats from three common arrhythmias with an 88% accuracy rate. In the process, the polymer network consumed less energy than a pacemaker. The potential applications for implantable AI systems are manifold: For example, they could be used to monitor cardiac arrhythmias or complications after surgery and report them to both doctors and patients via smartphone, allowing for swift medical assistance.

Samsung Pay can now store your coronavirus vaccination card on your smartphone in the U.S., thanks to the CommonHealth app on the Play Store.

After Google added support for COVID-19 vaccination cards to Google Pay, Samsung has now announced that it is doing the same with Samsung Pay. Users of the service will be able to load their SMART Health Cards displaying their COVID-19 vaccination status within Samsung Pay. This will allow U.S. consumers to download a verifiable digital version of their vaccination record from pharmacies or health systems and securely store in on their smartphone via the CommonHealth app on supported Samsung Galaxy smartphones.

“I should thank Persephone, our robot, she said very fine things,” said Christos Tenis, a Greek visitor. “I’m impressed by the cave. Of course, we had a flawless (human) guide, she explained many things. I’m very impressed.”

Persephone is not the only technology used inside the cave. There’s a cellphone app in which a visitor, scanning a QR code, can see the Alistrati Beroni. That’s a microorganism that is only found in this cave, in the huge mounds of bat droppings left behind when the cave was opened and the bats migrated elsewhere.

Optical image stabilization combined with a lot more zoom.

Apple has been beaten to the periscope “folded” camera punch by pretty much every other smartphone manufacturer, but it continues to design and patent new takes on the now-commonplace tech. It was granted a patent for a new design that includes folded optics and “lens shifting” capabilities.

Folded optics, or more commonly known as periscope cameras, are a design that allows smartphones to gain considerably more optical zoom than a typical lens design by placing the lens array parallel to the long edge of a smartphone body and bending the transmission of light to the sensor by using one or more prisms. The design has been used by Samsung, Huawei, and others to make smartphone cameras that sport massive optical zooming capabilities compared to what Apple offers.
