Breakthrough: Quantum computers will soon fit in your phone

Posted by in categories: mobile phones, quantum physics, supercomputing

“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 Has Returned to Android: It Can Empty Your Bank Accounts Without You Noticing It and It Is Hidden in These Apps in the Google Play Store

Posted by in categories: biotech/medical, cybercrime/malcode, mobile phones

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?

Implantable AI system developed for early detection and treatment of illnesses

Posted by in categories: biotech/medical, mobile phones, robotics/AI

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 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 ,” 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 vaccine card on your phone

Posted by in categories: biotech/medical, health, mobile phones

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.

Persephone, the robot guide, leads visitors in a Greek cave

Posted by in categories: mobile phones, robotics/AI

Markes listened to the first three stops from the robοt in his native language and the rest in English from a human tour guide.

“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.

Apple Has Designed a ‘Folded’ Camera With Optical Image Stabilization

Posted by in categories: electronics, mobile phones

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.

Smartphone camera measures blood glucose concentration

Posted by in categories: biotech/medical, mobile phones

Circa 2019


An add-on device for smartphones could replace blood glucose meters for measuring blood sugar. Blood sugar measurements are essential for diabetes patients who need to know their blood glucose concentration in order to regulate it with insulin. Failure to do so might result in complications from the disease. The device, designed by researchers in Taiwan, achieved 100% accuracy in a test with 20 blood samples from diabetes patients (J. Biomed. Opt. 10.1117/1.JBO.24.2.027002).

The researchers designed a compact device containing no electrical components that can be used in combination with a smartphone. The light from the smartphone’s display reflects onto the blood glucose test site (BGTS) inside the device, which contains a colorimetric test strip. The user adds a blood drop to the test strip, which is then assessed for a colour change using the phone’s front camera.

What You Need to Know About Solid-State Batteries

Posted by in categories: computing, engineering, mobile phones, sustainability, transportation

This next jump in battery-tech could solve a lot of EV problems.


The world of the internal combustion engine will sadly, but very necessarily, come to a close at some point in many of our lifetimes. Hybrids and electric vehicles are becoming more affordable and more advanced at a rapid pace, which means batteries are taking the place of fossil fuels. This has led to an equally rapid progression in battery technology, with the main goals of improving capacity, charging times, and safety. One major advancement in this field is the advent of solid-state batteries, which promise to push the boundaries of the limitations that current lithium-ion batteries carry.
