After ALS struck, he became the world’s most advanced cyborg

Posted by in categories: biological, cyborgs, robotics/AI

At this point, Scott-Morgan is almost completely “locked-in,” unable to move except for his eyes and a few facial muscles. His sense of smell and taste are gone, and he can’t breathe on his own, but his brilliant mind is fully intact.

Scott-Morgan now relies on a synthetic version of his biological voice and has had his face scanned to produce a 3D animated avatar, which he wears on a screen on his chest when speaking publicly. After a series of operations to extend his life, including a total laryngectomy, he uses technologies like GPT-2, OpenAI’s generative deep-learning model for text, pushing the boundaries of what it means to be human.

A Weird Paper Tests The Limits of Science

Posted by in categories: biological, science

Been saying this for years!


A summary of decades of research on a rather ‘out-there’ idea involving viruses from space raises questions on just how scientific we can be when it comes to speculating on the history of life on Earth.

Is Reality a Controlled Hallucination? — with Anil Seth

Posted by in categories: biological, computing, neuroscience

How does our biology give rise to the experience of consciousness?
Anil’s new book “Being You” is available now: https://geni.us/anil.
Watch the Q&A: https://youtu.be/JZS39CaODTs.

Anil Seth argues, using innovative combinations of theory and experiment, that our brains are prediction machines inventing our world and correcting our mistakes by the microsecond. Anil’s new perspective on consciousness has shed light on the nature of the self, free will, the intimate relationship between being alive and being aware — and the possibility of conscious machines.

Entanglement between superconducting qubits and a tardigrade

Posted by in categories: biological, chemistry, quantum physics

Quantum and biological systems are seldom discussed together as they seemingly demand opposing conditions. Life is complex, “hot and wet” whereas quantum objects are small, cold and well controlled. Here, we overcome this barrier with a tardigrade — a microscopic multicellular organism known to tolerate extreme physiochemical conditions via a latent state of life known as cryptobiosis. We observe coupling between the animal in cryptobiosis and a superconducting quantum bit and prepare a highly entangled state between this combined system and another qubit. The tardigrade itself is shown to be entangled with the remaining subsystems. The animal is then observed to return to its active form after 420 hours at sub 10 mK temperatures and pressure of $6\times 10^{-6}$ mbar, setting a new record for the conditions that a complex form of life can survive.

AI Researchers Fight Noise by Turning to Biology

Posted by in categories: biological, neuroscience, robotics/AI

Tiny amounts of artificial noise can fool neural networks, but not humans. Some researchers are looking to neuroscience for a fix.

Flexible tentaclelike robotic manipulators inspired by nature

Posted by in categories: biological, robotics/AI

Traditional robots can have difficulty grasping and manipulating soft objects if their manipulators are not flexible in the way elephant trunks, octopus tentacles, or human fingers can be.

In Applied Physics Reviews, investigators from Shanghai Jiao Tong University in China developed a type of multiple-segment soft manipulator inspired by these . The soft manipulators are based on pneu-nets, which are pneumatically actuated elastomeric structures.

These structures have a tentaclelike shape and consist of a series of connected internal chambers which can be inflated pneumatically, blowing them up like a balloon. One side of the tentacle is highly flexible while the other is stiffer. Increasing air pressure to the chambers causes the to bend toward the stiff side.

Meet the worm with a jaw of metal

Posted by in categories: biological, particle physics

So the bristle worm jaw is both metal-like and yet not. As Zelaya-Lainez puts it, “Here we are dealing with a completely different material, but interestingly, the metal atoms still provide strength and deformability there, just like in a piece of metal.”

Observing the creation of a metal-like material from biological processes is a bit of a surprise and may suggest new approaches to materials development. “Biology could serve as inspiration here,” says Hellmich, “for completely new kinds of materials. Perhaps it is even possible to produce high-performance materials in a biological way — much more efficiently and environmentally friendly than we manage today.”

Where does consciousness come from? And how do our brains create it? A look at one of life’s biggest mysteries

Posted by in categories: biological, chemistry, neuroscience

General anesthesia doesn’t just work on your brain or on your mind. It works on your consciousness. By altering the delicate electrochemical balance within the neural circuitry inside your head, the basic ground state of what it is to “be” is — temporarily — abolished. In this process lies one of the greatest remaining mysteries in science, and in philosophy too.

Somehow, within each of our brains, the combined activity of billions of neurons, each one a tiny biological machine, is giving rise to a conscious experience. And not just any conscious experience, your conscious experience, right here, right now.

“The Google Earth of Biology” — Visually Stunning Tree of All Known Life Unveiled Online

Posted by in categories: biological, evolution, existential risks, mapping, sustainability

OneZoom is a one-stop site for exploring all life on Earth, its evolutionary history, and how much of it is threatened with extinction.

The OneZoom explorer – available at onezoom.org – maps the connections between 2.2 million living species, the closest thing yet to a single view of all species known to science. The interactive tree of life allows users to zoom in to any species and explore its relationships with others, in a seamless visualisation on a single web page. The explorer also includes images of over 85,000 species, plus, where known, their vulnerability to extinction.

The Universe Might Be Able to Bend the Laws of Physics All By Itself

Posted by in categories: biological, cosmology, neuroscience, physics

At this point, the paper mingles cosmology, or the study of the universe and its origins, with biology. “We ask whether there might be a mechanism woven into the fabric of the natural world, by means of which the universe could learn its laws,” the authors write. In other words, a universal law might transcend all scientific fields. That means that the laws of physics, as we know them, could be subject to higher-order laws of the universe that control them—and that we can’t even comprehend.

“Exploring links between fields is crucial because knowledge is not fundamentally compartmentalized,” says Bruce Bassett, professor at the University of Cape Town’s Department of Mathematics and head of the Cosmology Group at the African Institute of Mathematical Sciences in South Africa. We humans are simply narrow-minded. “We segment and compress knowledge into biology, and physics, and sociology because of our limited brains, and the cost of that segmentation and compression is that we easily miss the commonalities and hidden universality between branches of human knowledge.”
