Biometric authentication like fingerprint and iris scans are a staple of any spy movie, and trying to circumvent those security measures is often a core plot point. But these days the technology is not limited to spies, as fingerprint verification and facial recognition are now common features on many of our phones.

Now, researchers have developed a new potential odorous option for the biometric security toolkit: your breath. In a report published in Chemical Communications, researchers from Kyushu University’s Institute for Materials Chemistry and Engineering, in collaboration with the University of Tokyo, have developed an olfactory sensor capable of identifying individuals by analyzing the compounds in their breath.

Combined with machine learning, this “artificial nose,” built with a 16-channel sensor array, was able to authenticate up to 20 individuals with an average accuracy of more than 97%.

When our phones and computers run out of power, their glowing screens go dark and they die a sort of digital death. But switch them to low-power mode to conserve energy, and they cut expendable operations to keep basic processes humming along until their batteries can be recharged.

Our energy-intensive brain needs to keep its lights on too. Brain cells depend primarily on steady deliveries of the sugar glucose, which they convert to adenosine triphosphate (ATP) to fuel their information processing. When we’re a little hungry, our brain usually doesn’t change its energy consumption much. But given that humans and other animals have historically faced the threat of long periods of starvation, sometimes seasonally, scientists have wondered whether brains might have their own kind of low-power mode for emergencies.

Now, in a paper published in Neuron in January, neuroscientists in Nathalie Rochefort’s lab at the University of Edinburgh have revealed an energy-saving strategy in the visual systems of mice. They found that when mice were deprived of sufficient food for weeks at a time — long enough for them to lose 15%-20% of their typical healthy weight — neurons in the visual cortex reduced the amount of ATP used at their synapses by a sizable 29%.

With a more sustainable world goal, MIT researchers have succeeded in developing a new LEGO-like AI chip. Imagine a world where cellphones, smartwatches, and other wearable technologies don’t have to be put away or discarded for a new model. Instead, they could be upgraded with the newest sensors and processors that would snap into a device’s internal chip – similar to how LEGO bricks can be incorporated into an existing structure. Such reconfigurable chips might keep devices current while lowering electronic waste. This is really important because green computing is the key to a sustainable future.

MIT engineers have developed a stackable, reprogrammable LEGO-like AI chip. The chip’s layers communicate thanks optically to alternating layers of sensing and processing components, as well as light-emitting diodes (LEDs). Other modular chip designs use conventional wiring to transmit signals between layers. Such intricate connections are difficult, if not impossible, to cut and rewire, making stackable configurations nonreconfigurable.

Rather than relying on physical wires, the MIT design uses light to transfer data across the AI chip. As a result, the chip’s layers may be swapped out or added upon, for example, to include extra sensors or more powerful processors.

Such reconfigurable chipware could keep devices up to date while reducing our electronic waste.

Now MIT engineers have taken a step toward that modular vision with a LEGO-like design for a stackable, reconfigurable artificial intelligence chip.

The design comprises alternating layers of sensing and processing elements, along with light-emitting diodes (LED) that allow for the chip’s layers to communicate optically. Other modular chip designs employ conventional wiring to relay signals between layers. Such intricate connections are difficult if not impossible to sever and rewire, making such stackable designs not reconfigurable.

Cybersecurity researchers have discovered adware and information-stealing malware on the Google Play Store last month, with at least five still available and having amassed over two million downloads.

Adware infections displaying unwanted advertisements that can be particularly intrusive, degrade the user experience, deplete the battery, generate heat, and even cause unauthorized charges.

This software generally tries to hide by masquerading as something else on the host device and makes money for remote operators by forcing the victim to perform views or clicks on affiliated advertisements.

There’s a lot going on when it comes to Apple’s rumored mixed reality headset, which is expected to combine both AR and VR technologies into a single device. However, at the same time, the company has also been working on new AR glasses. According to Haitong Intl Tech Research analyst Jeff Pu, Apple’s AR glasses will be announced in late 2024.

In a note seen by 9to5Mac, Pu mentions that Luxshare will remain as one of Apple’s main suppliers for devices to come between late 2022 and 2024. Among all devices, the analyst highlights products such as Apple Watch Series 8, iPhone 14, and Apple’s AR/VR headset. But more than that, Pu believes that Apple plans to introduce new AR glasses in the second half of 2024.

At this point, details about Apple’s AR glasses are unknown. What we do know so far is that, unlike Apple’s AR/VR headset, the new AR glasses will be highly dependent on the iPhone due to design limitations. Analyst Ming-Chi Kuo said in 2019 that the rumored “Apple Glasses” will act more like a display for the iPhone, similar to the first generation Apple Watch.

“I think it is possible,” Musk, 50, recently told Insider. “Yes, we could download the things that we believe make ourselves so unique. Now, of course, if you’re not in that body anymore, that is definitely going to be a difference, but as far as preserving our memories, our personality, I think we could do that.”

By Musk’s account, such technology will be a gradual evolution from today’s forms of computer memory. “Our memories are stored in our phones and computers with pictures and video,” he said. “Computers and phones amplify our ability to communicate, enabling us to do things that would have been considered magical … We’ve already amplified our human brains massively with computers.”

Wood-derived materials can be used to harvest electrical energy from everyday movements such as walking, according to University of Toronto and University of Waterloo researchers.

In a new study recently published in Nano Energy, the team demonstrated the use of lignocellulosic nanofibrils—derived from tree bark —in a prototype self-powered device capable of sending a wireless signal to a smartphone via bluetooth.

Such devices can be used to track biometric data such as heart rate, oxygen levels or skin conductivity. The innovation could improve the performance of these devices while lowering their environmental impact.

A new study has shown for the first time that the Bluetooth signals constantly emitted by our smartphones have a unique fingerprint.
