Elon Musk doesn’t follow the same standards that most entrepreneurs do. He’s different, he likes to be different!

And when you’re different, and you’re not afraid to be, it’s okay to test a cigar (or should I say ‘joint’?) of tobacco mixed with marijuana, on Joe Rogan’s famous podcast. But if you look closely, Elon was just nice (polite) and followed Rogan’s elaborate script. Before trying it, Musk even asked him if it was legal.

Then all those facial expressions of Musk, which photojournalists love to catch, go viral as if he’s there promoting some soft drug or passing abroad that his office at Tesla (or SpaceX) is enveloped in a large cloud of smoke.

Quite the opposite. The expressions themselves spoke for themselves, as if to say, “This is nothing special, Joe. Why do you waste my time with these scenes”? Musk even claimed that weed is not good for productivity at all, but it has nothing against (as I do, by the way).

A material has been created that imitates how the brain stores information

Posted by in category: computing

The magnetic material emulates learning that occurs in the brain during deep sleep.

Researchers have developed a material that can replicate the way the brain stores information. The material works by copying the synapses of neurons, allowing it to mimic learning that occurs during deep sleep. The team of researchers, from the Universitat Autònoma de Barcelona (UAB), built the magnetic material using a type of computation called neuromorphic computing.

Neuromorphic computing is a computing concept that uses artificial neurons to mimic behavior of the brain and the synaptic functions, or communication signals, of neurons.

Brainwave-reading implant lets paralyzed man spell out 1,100 words

Posted by in categories: biotech/medical, computing, cyborgs, neuroscience

A paralyzed man who cannot speak or type was able to spell out over 1,000 words using a neuroprosthetic device that translates his brain waves into full sentences, US researchers said Tuesday.

“Anything is possible,” was one of the man’s favorite phrases to spell out, said the first author of a new study on the research, Sean Metzger of the University of California San Francisco (UCSF).

The James Webb Space Telescope has revolutionized the way we look at the universe in less.
than a year. Since its launch on December 25, 2021 multiple images captured by the largest.
telescope with potentially the highest infrared resolution and sensitivity have been going viral.
around the globe. James Webb is no doubt the most advanced telescope in human history. The.
telescope’s integrated science instrument module or ISIM framework provides it with electrical.
power, computing framework, cooling capability and structural stability. The ISIM also holds the.
four science instruments and the guide camera of the telescope. The infrared imager NIRICam.
serves as the Observatory’s wavefront sensor while the NIRISpec performs spectroscopy over.
the same wavelength range as that of NIRICam. The Mid-Infrared Instrument measures the mid.
to long infrared wavelengths and the Fine Guidance Center and Near Infrared Imager and.
Slitless Spectrograph is used to stabilize the line of sight during the science observations. So far.
the images and data received from the JWST are well worth the ten billion spent on building this.
miraculous invention. The first ever in ages from the telescope were revealed to the world on.
July 12, 2022 and experts believe these pictures from the largest and most powerful telescope.
in the world demonstrate Webb at its absolute best, fully prepared to further unravel the infrared universe. These included images of cosmic cliffs in the carina nebula, exoplanet WASP-06b.
southern ring nebula, Stephen’s quintet and the brilliant deep field view of the universe. But.
these were just the first batch, since then the James Webb Telescope has provided scientists.
with even more dazzling and awe-inspiring images of the cosmos. Some of these images have.
left astronomers and cosmologists quite confused. A flood of astronomical papers has been.
published since the revelation of these images and data from the JWST, a few of these papers.
have incited panic among the cosmologists. But what exactly is the reason behind this wave of.
panic? Well, it’s the assumption that the findings of James Webb Space Telescope are blatantly.
and repeatedly contradicting the Big Bang Theory. In order to better understand what’s going.
on, we first need to understand what the Big Bang exactly is.

100 Times Longer Than Previous Benchmarks — A Quantum Breakthrough

Posted by in categories: computing, quantum physics

On these timescales, a blink of an eye — one-tenth of a second — seems like eternity.

Researchers from the University of New South Wales have now broken new ground in demonstrating that ‘spin qubits,’ which are the fundamental informational units of quantum computers, can store data for up to two milliseconds. The accomplishment is 100 times longer than prior benchmarks in the same quantum processor for what is known as “coherence time,” the amount of time qubits can be manipulated in increasingly complicated calculations.

Digital Doubles and Second Selves

Posted by in categories: augmented reality, automation, big data, computing, cyborgs, evolution, futurism, information science, innovation, internet, life extension, machine learning, neuroscience, posthumanism, robotics/AI, singularity, software, supercomputing

This time I come to talk about a new concept in this Age of Artificial Intelligence and the already insipid world of Social Networks. Initially, quite a few years ago, I named it “Counterpart” (long before the TV series “Counterpart” and “Black Mirror”, or even the movie “Transcendence”).

It was the essence of the ETER9 Project that was taking shape in my head.

Over the years and also with the evolution of technologies — and of the human being himself —, the concept “Counterpart” has been getting better and, with each passing day, it makes more sense!

Imagine a purely digital receptacle with the basics inside, like that Intermediate Software (BIOS(1)) that computers have between the Hardware and the Operating System. That receptacle waits for you. One way or another, it waits patiently for you, as if waiting for a Soul to come alive in the ether of digital existence.

Scientists Tap Into Biology’s ‘Mirror Dimension’ to Create Ultra-Strong Synthetic RNA

Posted by in categories: biotech/medical, computing, genetics

Even more daring, biology’s “mirror dimension” may be a springboard to engineer synthetic life forms that exist outside of nature, but are literal reflections of ourselves. To rephrase: building a mirror-image version of biology means rewriting the fundamental operating system of life.

Sound a bit too sci-fi? Let me explain. Similar to how our left hand can’t wear a right-hand glove, the building blocks of life—DNA, RNA, and proteins—are etched into specific 3D structures. Flip them around, as if reflected by a mirror, and they can no longer function inside the body. Scientists aren’t yet sure why nature picked just one shape out of two potential mirror images. But they’re ready to test it out.

A new study in Science made strides by reworking parts of the body’s protein-making machine into its mirror image. At the center is a structure called the ribosome, which intakes genetic code and translates it into amino acids—the Lego blocks for all proteins. The ribosome is an iconic cellular architecture, fused from two main molecular components: RNA and proteins.

Quantum Cryptography Is Unbreakable. So Is Human Ingenuity

face_with_colon_three circa 2016.


Two basic types of encryption schemes are used on the internet today. One, known as symmetric-key cryptography, follows the same pattern that people have been using to send secret messages for thousands of years. If Alice wants to send Bob a secret message, they start by getting together somewhere they can’t be overheard and agree on a secret key; later, when they are separated, they can use this key to send messages that Eve the eavesdropper can’t understand even if she overhears them. This is the sort of encryption used when you set up an online account with your neighborhood bank; you and your bank already know private information about each other, and use that information to set up a secret password to protect your messages.

The second scheme is called public-key cryptography, and it was invented only in the 1970s. As the name suggests, these are systems where Alice and Bob agree on their key, or part of it, by exchanging only public information. This is incredibly useful in modern electronic commerce: if you want to send your credit card number safely over the internet to Amazon, for instance, you don’t want to have to drive to their headquarters to have a secret meeting first. Public-key systems rely on the fact that some mathematical processes seem to be easy to do, but difficult to undo. For example, for Alice to take two large whole numbers and multiply them is relatively easy; for Eve to take the result and recover the original numbers seems much harder.

Public-key cryptography was invented by researchers at the Government Communications Headquarters (GCHQ) — the British equivalent (more or less) of the US National Security Agency (NSA) — who wanted to protect communications between a large number of people in a security organization. Their work was classified, and the British government neither used it nor allowed it to be released to the public. The idea of electronic commerce apparently never occurred to them. A few years later, academic researchers at Stanford and MIT rediscovered public-key systems. This time they were thinking about the benefits that widespread cryptography could bring to everyday people, not least the ability to do business over computers.

Gate-tunable heterojunction tunnel triodes based on 2D metal selenide and 3D silicon

Posted by in categories: computing, materials

Electronics engineers worldwide are trying to improve the performance of devices, while also lowering their power consumption. Tunnel field-effect transistors (TFETs), an experimental class of transistors with a unique switching mechanism, could be a particularly promising solution for developing low-power electronics.

Despite their potential, most TFETs based on silicon and III-V heterojunctions exhibit low on-current densities and on/off current ratios in some modes of operation. Fabricating these transistors using 2D materials could help to improve electrostatic control, potentially increasing their on-current densities and on/off ratios.

Researchers at University of Pennsylvania, the Chinese Academy of Sciences, the National Institute of Standards and Technology, and the Air Force Research Laboratory have recently developed new heterojunction tunnel triodes based on van der Waals heterostructures formed from 2D metal selenide and 3D silicon. These triodes, presented in a paper published in Nature Electronics, could outperform other TFETs presented in the past in terms of on-current densities and on/off ratios.
