Elon Musk’s Neuralink is neuroscience theater

Posted by in categories: biotech/medical, computing, Elon Musk, neuroscience

Rock-climb without fear. Play a symphony in your head. See radar with superhuman vision. Discover the nature of consciousness. Cure blindness, paralysis, deafness, and mental illness. Those are just a few of the applications that Elon Musk and employees at his four-year-old neuroscience company Neuralink believe electronic brain-computer interfaces will one day bring about.

None of these advances are close at hand, and some are unlikely to ever come about. But in a “product update” streamed over YouTube on Friday, Musk, also the founder of SpaceX and Tesla Motors, joined staffers wearing black masks to discuss the company’s work toward an affordable, reliable brain implant that Musk believes billions of consumers will clamor for in the future.

Optical Computing: Solving Problems at the Speed of Light

Posted by in categories: computing, internet, quantum physics

Optical computing, which uses photons instead of electrons, has been one of the great promises of this field for decades.


According to Moore’s law —actually more like a forecast, formulated in 1965 by Intel co-founder Gordon Moore— the number of transistors in a microprocessor doubles about every two years, boosting the power of the chips without increasing their energy consumption. For half a century, Moore’s prescient vision has presided over the spectacular progress made in the world of computing. However, by 2015, the engineer himself predicted that we are reaching a saturation point in current technology. Today, quantum computing holds out hope for a new technological leap, but there is another option on which many are pinning their hopes: optical computing, which replaces electronics (electrons) with light (photons).

The end of Moore’s law is a natural consequence of physics: to pack more transistors into the same space they have to be shrunk down, which increases their speed while simultaneously reducing their energy consumption. The miniaturisation of silicon transistors has succeeded in breaking the 7-nanometre barrier, which used to be considered the limit, but this reduction cannot continue indefinitely. And although more powerful systems can always be obtained by increasing the number of transistors, in doing so the processing speed will decrease and the heat of the chips will rise.

Extreme events in quantum cascade lasers

Posted by in categories: biological, climatology, computing, neuroscience, quantum physics

Extreme events occur in many observable contexts. Nature is a prolific source: rogue water waves surging high above the swell, monsoon rains, wildfire, etc. From climate science to optics, physicists have classified the characteristics of extreme events, extending the notion to their respective domains of expertise. For instance, extreme events can take place in telecommunication data streams. In fiber-optic communications where a vast number of spatio-temporal fluctuations can occur in transoceanic systems, a sudden surge is an extreme event that must be suppressed, as it can potentially alter components associated with the physical layer or disrupt the transmission of private messages.

Recently, extreme events have been observed in quantum cascade lasers, as reported by researchers from Télécom Paris (France) in collaboration with UC Los Angeles (USA) and TU Darmstad (Germany). The giant pulses that characterize these extreme events can contribute the sudden, sharp bursts necessary for communication in neuromorphic systems inspired by the brain’s powerful computational abilities. Based on a quantum cascade laser (QCL) emitting mid-infrared light, the researchers developed a basic optical neuron system operating 10,000× faster than biological neurons. Their report is published in Advanced Photonics.

New Chrome 0-day Under Active Attacks – Update Your Browser Now

Posted by in categories: computing, security

Attention readers, if you are using Google Chrome browser on your Windows, Mac, or Linux computers, you need to update your web browsing software immediately to the latest version Google released earlier today.

Google released Chrome version 86.0.4240.111 today to patch several security high-severity issues, including a zero-day vulnerability that has been exploited in the wild by attackers to hijack targeted computers.

Tracked as CVE-2020–15999, the actively exploited vulnerability is a type of memory-corruption flaw called heap buffer overflow in Freetype, a popular open source software development library for rendering fonts that comes packaged with Chrome.

Scientists borrow solar panel tech to create new ultrahigh-res OLED display

Posted by in categories: augmented reality, computing, mobile phones, solar power, sustainability

Ultra high-res displays for gadgets and tv sets may be coming. 😃


By expanding on existing designs for electrodes of ultra-thin solar panels, Stanford researchers and collaborators in Korea have developed a new architecture for OLED—organic light-emitting diode—displays that could enable televisions, smartphones and virtual or augmented reality devices with resolutions of up to 10,000 pixels per inch (PPI). (For comparison, the resolutions of new smartphones are around 400 to 500 PPI.)

Such high-pixel-density displays will be able to provide stunning images with true-to-life detail—something that will be even more important for headset displays designed to sit just centimeters from our faces.

Biomimicry has positive impact on planet says architect Michael Pawlyn

Posted by in categories: computing, innovation

In the second video of our Design for Life collaboration with Dassault Systèmes, Exploration Architecture founder Michael Pawlyn explains how computational design tools allow architects to mimic the natural world.

Pawlyn is the second designer to feature in the Design for Life collaboration between Dezeen and Dassault Systèmes, which highlights designers who are using technology and research to build a better world.

Biomimicry is innovation inspired by nature,” explained Pawlyn in the video, which was filmed by Dezeen at the founder of biomimicry-focussed practice Exploration Architecture’s home studio in London.
