More hidden numbers – Or a glimpse of the Mind of God?

A couple of years ago, we published a little blog in which we dared to suggest that the recurrence of certain numbers, such as pi and Euler‘s might hint at deeper universal phenomena that are not yet fully understood.(LSS 14 3 22) So we were more than gratified to come across an intriguing article by Steven Pappas for Live Science which further confirms our suspicions.

A team led by Vaibhev Mohanty at MIT has been trying to answer a simple but profound question. “How many mutations do you need in a genome before it changes the phenotype( i.e. proteins, etc) of the carrying organism? Now, we will confess at this point that our grasp of mathematics is appalling. However:

Scientists have discovered that a key function from a “pure” branch of mathematics can predict how often genetic mutations lead to changes in function. These rules, laid out by the so-called sum-of-digits function, also govern some aspects of protein folding, computer coding and certain magnetic states in physics.

The report explains, in verbal form, some more about how the team arrived at these conclusions. But for us the key is that the same mathematics applies across several fields of science, as though something much deeper is going on. Well, that’s what we speculate. But we were not the first. As educated readers will recall, Plato speculated that the universe was formed of deep underlying structures, which he termed “forms”. And in his view a single Divine mind had created the universe through these same forms. So we pose this question: have these scientists, and others, had a tiny glimpse of the Mind of God?

Two stories that hint how we may become a new species

Things aren’t going too well for poor old Homo sapiens. Like a bacterial colony in a petri dish, we are starting to use up our resources fast, and pathological symptoms are appearing. When a species runs up against its ecological limits, it is quickly replaced by better adapted competitors. Two stories from Nature Briefings indicate how things might go. And that we have a way out of this if we are prepared to adapt.

Report Charts machines meteoric rise Better at maths. Better at pattern recognition. Better at reading. Remember that bright kid in the class? Next time you heard of him was twenty years later and he was Chief Executive Officer of a blue chip corporation. Well, that’s the way it is with AI now. .

Artificial intelligence (AI) systems can now nearly match — and sometimes exceed — human performance in tasks such as reading comprehension, image classification and mathematics. “The pace of gain has been startlingly rapid,” says social scientist Nestor Maslej, editor-in-chief of the annual AI Index. The report calls for new benchmarks to assess algorithms’ capabilities and highlights the need for a consensus on what ethical AI models would look like.Nature | 6 min read

Milestone Map of Brain Connectivity Yet there may be a chance of survival. First read this

Researchers have mapped the tens of thousands of cells and connections between them in one cubic millimetre of the mouse brain. The project, which took US$100 million and years of effort by more than 100 scientists, is a milestone of ‘connectomics’, which aims to chart the circuits that coordinate the organ’s many functions. Identifying the brain’s architectural principles could one day guide the development of artificial neural networks. Teams are now working on mapping larger areas, although a whole-brain reconstruction “may be a ‘Mars shot’ — it’s really much harder than going to the Moon”, says connectomics pioneer Jeff Lichtman.

The point is that AI and mammal brains have one thing in common. Both depend on networks and the system control architecture that runs them. In theory it should be possible to create beings which fuse AI with biological neurons. This has already begun, in a small way, with things like brain implants and limb attachments which can interface with the nervous system. It is possible to imagine biocyber hybrids with advanced intellectual and physical capacities which are ready for the challenges of the future. It looks as if Homo sapiens itself may no longer be up to it. But the genus Homo will survive, albeit in modified form. Which has happened successfully before. We’ll leave you with some thoughts from the old British Rocker David Bowie, who memorably observed

The earth is a bitch, we’ve finished our news/Homo sapiens have outgrown their use

Which is the exact text of this blog. He just said it better.

Two amazing stories from genetics that woke us up this morning

One of our great pleasures in life is to stand amazed when someone does something amazingly clever. Especially when you get that feeling that what they did was there, waiting to be done, all along. Which is why we bring you two such stories, all gift wrapped up by the admirable Nature Briefings and BBC, for you to click on at your delight.

A Cure for HIV? Anyone who lived through the 1980s will recall the terrible ravages of the AIDS pandemic, caused of course by the HIV virus. Even if you were lucky enough to be in a low-risk group, we all knew someone or a local community organisation who suffered the ravages. Sad. Sad. Sad. Now that old friend of LSS, CRISPR gene editing may actually offer some hope towards the final elimination of the virus from our genomes. It’s early days yet, as both Michelle Roberts of the BBC and the researchers themselves say. Proof of concept and all that. Good, it’s better to be cautious. But if they can “snip” the HIV virus out of your cells, what else might not be achieved?[1]

Ghost DNA made us brainy Talking of embedded DNA, many a 1980s conversation concerned all that mysterious DNA lying around our genomes that didn’t seem to do anything (no, it was mainly about EastEnders-ed) Was it some of it ancient embedded viruses that attacked our ancestors long ago, in some forgotten Permian Pandemic? Well, get this from Nature Briefings, Virus Helped Brain Evolution

Remnants of an ancient viral infection are essential for producing myelin, a protein that insulates nerve fibres, in most vertebrates. Certain viruses insert DNA into the genetic material of the cells they invade. Sometimes, these insertions become permanent and even aid evolutionary processes. Myelin helps nerves to send electrical signals faster, grow longer and thinner so they can be packed in more efficiently. “As a result of myelin, brains became more complex and vertebrates became more diverse,” says stem-cell biologist and study co-author Robin Franklin.Science News | 6 min read

The implications are rather profound. The idea of the single autonomous gene line, the pure selfish individual at the core of your biological identity is rather compromised, isn’t it? What if the genetic “you” isn’t just “you,” but is you+some (rather random )free riders, who may or may not be helpful? That Natural Selection is acting on several of you at once. and may force you to cooperate? What price The Selfish Gene now?
