These Advanced Nootropics Are Specially Formulated to Help Fight Mental Fatigue

Posted by in categories: biological, neuroscience

Supplement companies often market nootropics like they’re some kind of new scientific discovery. However, human beings have been using nootropics to boost mental performance for millennia. What’s different now is that scientists actually understand how nootropics work, and which ones have synergistic interactions with each other.

This new understanding is what helped TruBrain create Brain Food.

Brain Food is a nutritional supplement that has been methodically engineered by TruBrain’s team of scientists to create the biological conditions necessary for peak cognitive performance. Like a lot of other nootropic supplements, Brain Food contains the so-called “everyman stack” of caffeine and l-theanine, a combo humans have been taking for thousands of years in the form of green tea.

Biological Anchors: A Trick That Might Or Might Not Work

Posted by in categories: biological, robotics/AI

I’ve been trying to review and summarize Eliezer Yudkowksy’s recent dialogues on AI safety. Previously in sequence: Yudkowsky Contra Ngo On Agents. Now we’re up to Yudkowsky contra Cotra on biological anchors, but before we get there we need to figure out what Cotra’s talking about and what’s going on.

The Open Philanthropy Project (“Open Phil”) is a big effective altruist foundation interested in funding AI safety. It’s got $20 billion, probably the majority of money in the field, so its decisions matter a lot and it’s very invested in getting things right. In 2020, it asked senior researcher Ajeya Cotra to produce a report on when human-level AI would arrive. It says the resulting document is “informal” — but it’s 169 pages long and likely to affect millions of dollars in funding, which some might describe as making it kind of formal. The report finds a 10% chance of “transformative AI” by 2031, a 50% chance by 2052, and an almost 80% chance by 2100.

Eliezer rejects their methodology and expects AI earlier (he doesn’t offer many numbers, but here he gives Bryan Caplan 50–50 odds on 2030, albeit not totally seriously). He made the case in his own very long essay, Biology-Inspired AGI Timelines: The Trick That Never Works, sparking a bunch of arguments and counterarguments and even more long essays.

Cooler waters created super-sized Megalodon, latest study shows

Posted by in category: biological

A new study reveals that the iconic extinct Megalodon or megatooth shark grew to larger sizes in cooler environments than in warmer areas.

DePaul University paleobiology professor Kenshu Shimada and coauthors take a renewed look through time and space at the body size patterns of Otodus , the fossil shark that lived nearly worldwide roughly 15 to 3.6 million years ago. The new study appears in the international journal Historical Biology.

Otodus megalodon is commonly portrayed as a gigantic, monstrous shark in novels and films, such as the 2018 sci-fi thriller “The Meg.” In reality, this species is only known from teeth and vertebrae in the , although it is generally accepted scientifically that the species was indeed quite gigantic, growing to at least 50 feet (15 meters) and possibly as much as 65 feet (20 meters). The new study re-examined published records of geographic occurrences of Megalodon teeth along with their estimated total body lengths.

We are entering the era of AI biological robots. How can we harness this powerful innovation so it doesn’t control us?

Posted by in categories: biological, robotics/AI

It should come as little surprise that pioneering work in biological robotics is as controversial as it is exciting. Take for example the article published in December 2021 in the Proceedings of the National Academy of Sciences by Sam Kreigman and Douglas Blackiston at Tufts University and colleagues. This article, entitled “Kinematic self-replication in reconfigurable organisms,” is the third installment of the authors’ “xenobots” series.

Researchers Build Neural Networks With Actual Neurons

Posted by in categories: biological, robotics/AI

Neural networks have become a hot topic over the last decade, put to work on jobs from recognizing image content to generating text and even playing video games. However, these artificial neural networks are essentially just piles of maths inside a computer, and while they are capable of great things, the technology hasn’t yet shown the capability to produce genuine intelligence.

Cortical Labs, based down in Melbourne, Australia, has a different approach. Rather than rely solely on silicon, their work involves growing real biological neurons on electrode arrays, allowing them to be interfaced with digital systems. Their latest work has shown promise that these real biological neural networks can be made to learn, according to a pre-print paper that is yet to go through peer review.

The broad aim of the work is to harness biological neurons for their computational power, in an attempt to create “synthetic biological intelligence”. The general idea is that biological neurons have far more complexity and capability than any neural networks simulated in software. Thus, if one wishes to create a viable intelligence from scratch, it makes more sense to use biological neurons rather than messing about with human-created simulations of such.

Universal Consciousness | Part IV of Consciousness: Evolution of the Mind (2021) Documentary

Posted by in categories: biological, education, life extension, neuroscience, robotics/AI, singularity

There’s only one Universal Consciousness, we individualize our conscious awareness through the filter of our nervous system, our “local” mind, our very inner subjectivity, but consciousness itself, the Self in a greater sense, our “core” self is universal, and knowing it through experience has been called enlightenment, illumination, awakening, or transcendence, through the ages.

Artificial neurons connect to biological ones to control living plants

Posted by in categories: biological, chemistry, computing, space

Nature is a never-ending source of inspiration for scientists, but our artificial devices usually don’t communicate well with the real thing. Now, researchers at Linköping University have created artificial organic neurons and synapses that can integrate with natural biological systems, and demonstrated this by making a Venus flytrap close on demand.

The new artificial neurons build on the team’s earlier versions, which were organic electrochemical circuits printed onto thin plastic film. Since they’re made out of polymers that can conduct either positive or negative ions, these circuits form the basis of transistors. In the new study, the team optimized these transistors and used them to build artificial neurons and synapses, and connect them to biological systems.

When the transistors detect concentrations of ions with certain charges, they switch, producing a signal that can then be picked up by other neurons. Importantly, biological neurons operate on these same ion signals, meaning artificial and natural nerve cells can be connected.
