Dr. Hologram will see you now: Virtual specialists visit cancer patients

Back in August 2021, LA-based Portl launched a 7-ft-tall hologram projection box for life-like remote communications. Now renamed Proto, the company has revealed that its Epic technology is allowing cancer patients to consult life-size virtual specialists.

Proto was founded in 2018 by David Nussbaum, who took his experience working on huge holograms for arena gigs, movie premieres and fashion shows to produce a hologram in a box called the Epic. The idea is to plonk the machine in a venue, university, boardroom, medical facility and so on, and allow folks to chat with a life-like 3D hologram of a person who might be thousands of miles away.

So instead of a tiny image on a smartphone screen, the viewer essentially gets to interact with someone as if they’re actually in the room for a more natural communications experience. LED lighting inside the box helps with shadows and reflections for added realism, the front of the unit is touch-enabled, microphones and speakers are cooked in, and there are AI-powered cameras onboard too.

New PIXHELL acoustic attack leaks secrets from LCD screen noise

A novel acoustic attack named ‘PIXHELL’ can leak secrets from air-gapped and audio-gapped systems, and without requiring speakers, through the LCD monitors they connect to.

In a PIXHELL attack, malware modulates the pixel patterns on LCD screens to induce noise in the frequency range of 0–22 kHz, carrying encoded signals within those acoustic waves that can be captured by nearby devices such as smartphones.

The researchers’ tests showed that data exfiltration is possible at a maximum distance of 2 meters (6.5 ft), achieving a data rate of 20 bits per second (bps).

Facebook partner admits to eavesdropping on conversations via phone mics for ad targeting

A hot potato: For almost as long as we’ve had smartphones, there has been the belief that they surreptitiously listen to our spoken conversations to serve us targeted ads; most people have experienced seeing an ad on Facebook for something they were recently talking about. It’s always been claimed that this type of privacy invasion doesn’t happen. However, a marketing agency, whose clients included Facebook and Google, has admitted to using an “Active Listening” feature that eavesdrops on conversations via phone mics to gather data.

A pitch deck from Cox Media Group (CMG), seen by 404 Media, states that the marketing firm uses its AI-powered Active Listening software to capture real-time data by listening to phone users’ conversations. The slide adds that advertising clients can pair the gathered voice data with behavioral data to target in-market consumers.

Radical New Super-Tough Transistor Could Revolutionize Electronics

A newly developed transistor device has shown exceptional levels of resilience in tests, performing so well, in fact, that it promises to transform the electronics and gadgets we make use of each day.

These tiny toggles are essential in just about every modern day electronic device, involved in storing data and processing information in a binary ‘on’ or ‘off’ state, switching back and forth multiple times a second.

Thanks to its remarkable combination of speed, size, and resilience to wear, this latest design potentially represents a huge upgrade for consumer devices like phones and laptops, as well as the data centers that store all of our information in the cloud.

Psychologists reveals the morbid reason we take so many selfies

Why do we take so many selfies? Because we are afraid of dying, say psychologists.

Many of us have phones filled with selfies documenting everything from holidays to duvet days.

But what’s behind the modern fascination with taking photos of ourselves?

Psychologists have come up with a rather morbid answer: fear of dying.

Researchers from Tel Aviv University in Israel quizzed 100 students on the motivations behind their selfie-taking.

Achieving a supercapacitor through the ‘molecular coating’ approach

Researchers at Tohoku University have successfully increased the capacity, lifetime durability, and cost-effectiveness of a capacitor in their pursuit of a more power-efficient future. The research is published in the journal ACS Applied Materials & Interfaces.

A capacitor is a device used as part of a circuit that can store and release energy, just like a battery. What makes a capacitor different from a battery is that it takes much less time to charge. For example, your cellphone battery will power your phone instantly, but charging that back up to 100% when it dies is far from instantaneous.

While this makes capacitors sound like the superior choice, they have some big drawbacks that need to be overcome. First, their is much smaller than batteries, so they cannot store large amounts of energy at once. Second, they can be quite expensive.
