President of Elon Musk’s Neuralink venture tweets that he’s left the company

Posted by in categories: computing, Elon Musk, neuroscience

Neuralink President Max Hodak tweeted Saturday that he has left the company he co-founded with Tesla and SpaceX CEO Elon Musk. Hodak didn’t elaborate on why he left the company or elaborate on the circumstance for his departure. “I am no longer at Neuralink (as of a few weeks ago),” he tweeted. “I learned a ton there and remain a huge cheerleader for the company! Onward to new things.”

New Brain-Like Computing Device With Electrochemical “Synaptic Transistors” Simulates Human Learning

Posted by in categories: chemistry, computing, food, neuroscience

Researchers have developed a brain-like computing device that is capable of learning by association.

Similar to how famed physiologist Ivan Pavlov conditioned dogs to associate a bell with food, researchers at Northwestern University and the University of Hong Kong successfully conditioned their circuit to associate light with pressure.

The research will be published today (April 30, 2021) in the journal Nature Communications.

Advances in Detectors: The Quanta image sensor (QIS): Making every photon count

Posted by in categories: computing, mobile phones, space

One of the interesting consequences of the emergent upshift in visual systems is that all streetlights, car headlights and other external sources of lighting will no longer be needed within around a decade. This will not only make astronomers happy, since they will be able to see the dark skies again but will simplify urban infrastructure. The three convergent elements making this change of affairs come about are the following:

1) Quanta Image Sensors, whether of the SPAD or the CIS-QIS versions are expected to become widely available within 5 to 10 years. Unlike the CMOS image sensors in billions of cell-phone cameras, which only register packets of the incoming light, these sensors can register single photons of light. The most versatile of these are the QIS sensors being developed by Fossum—who also developed the CMOS sensor—wherein a single jot\.

Intel seeks $10 billion in subsidies for European chip plant

Posted by in category: computing

BRUSSELS/BERLIN (Reuters)-Intel wants 8 billion euros ($9.7 billion) in public subsidies towards building a semiconductor factory in Europe, its CEO was cited as saying on Friday, as the region seeks to reduce its reliance on imports amid a shortage of supplies. The pitch is the first time Pat Gelsinger has publicly put a figure on how much state aid he would want, as Intel pursues a multibillion-dollar drive to take on Asian rivals in contract manufacturing. “What we’re asking from both the U.S. and the European governments is to make it competitive for us to do it here compared to in Asia,” Gelsinger told Politico Europe in an interview.

Intel Motherboard Lands With 32 SATA Ports For Farming Chia

Posted by in categories: computing, cryptocurrencies, entertainment

Let the farming games begin.


Chinese motherboard manufacturer Onda (via ZOL) has launched the brand’s new Chia-D32H-D4 motherboard. The model name alone is enough to tell you that this motherboard is aimed at farming Chia cryptocurrency, which has already caused hard drive price spikes in Asia.

Designed for mining, rather than to compete with the best motherboards for gaming, the Chia-D32H-D4 is most likely a rebranded version of Onda’s existing B365 D32-D4 motherboard. It measures 530 × 310mm, so the Chia-D32H-D4 isn’t your typical motherboard. In fact, Onda has produced a special case with an included power supply for this specific model. The unspecified 800W power supply arrives with the 80Plus Gold certification, while the case features five cooling fans.

Efficient Quantum-Mechanical Interface Leads to a Strong Interaction Between Light and Matter

Posted by in categories: computing, particle physics, quantum physics

Circa 2020 o.o!


Researchers have succeeded in creating an efficient quantum-mechanical light-matter interface using a microscopic cavity. Within this cavity, a single photon is emitted and absorbed up to 10 times by an artificial atom. This opens up new prospects for quantum technology, report physicists at the University of Basel and Ruhr-University Bochum in the journal Nature.

Quantum physics describes photons as light particles. Achieving an interaction between a single photon and a single atom is a huge challenge due to the tiny size of the atom. However, sending the photon past the atom several times by means of mirrors significantly increases the probability of an interaction.

The U. S. Air Force Research Laboratory (AFRL) and American Semiconductor have combined traditional manufacturing techniques with 3D printed circuitry to produce a flexible Silicon-on-polymer chip.

Besides its material qualities, the new chip has a memory more than 7000 times larger than any comparable commercially available devices, making it suitable as a micro-controller to be integrated into other objects.

More Compact and Efficient Vertical Turbines Could Be the Future for Wind Farms

Posted by in categories: computing, engineering, mathematics, sustainability

The now-familiar sight of traditional propeller wind turbines could be replaced in the future with wind farms containing more compact and efficient vertical turbines.

New research from Oxford Brookes University has found that the vertical turbine design is far more efficient than traditional turbines in large-scale wind farms, and when set in pairs the vertical turbines increase each other’s performance by up to 15%.

A research team from the School of Engineering, Computing and Mathematics (ECM) at Oxford Brookes led by Professor Iakovos Tzanakis conducted an in-depth study using more than 11500 hours of computer simulation to show that wind farms can perform more efficiently by substituting the traditional propeller-type Horizontal Axis Wind Turbines (HAWTs), for compact Vertical Axis Wind Turbines (VAWTs).

Nvidia Entangled in Quantum Simulators

Posted by in categories: computing, information science, quantum physics

Quantum simulators are a strange breed of systems for purposes that might seem a bit nebulous from the outset. These are often HPC clusters with fast interconnects and powerful server processors (although not usually equipped with accelerators) that run a literal simulation of how various quantum circuits function for design and testing of quantum hardware and algorithms. Quantum simulators do more than just test. They can also be used to emulate quantum problem solving and serve as a novel approach to tackling problems without all the quantum hardware complexity.

Despite the various uses, there’s only so much commercial demand for quantum simulators. Companies like IBM have their own internally and for others, Atos/Bull have created these based on their big memory Sequanna systems but these are, as one might imagine, niche machines for special purposes. Nonetheless, Nvidia sees enough opportunity in this arena to make an announcement at their GTC event about the performance of quantum simulators using the DGX A100 and its own custom-cooked quantum development software stack, called CuQuantum.

After all, it is probably important for Nvidia to have some kind of stake in quantum before (and if) it ever really takes off, especially in large-scale and scientific computing. What better way to get an insider view than to work with quantum hardware and software developers who are designing better codes and qubits via a benchmark and testing environment?
