*Intelligence Beyond the Brain: morphogenesis as an example of the scaling of basal cognition*

*Description:*
Each of us takes the remarkable journey from physics to mind: we start life as a quiescent oocyte (collection of chemical reactions) and slowly change and acquire an advanced, centralized mind. How does unified complex cognition emerge from the collective intelligence of cells? In this talk, I will use morphogenesis to illustrate how evolution scales cognition across problem spaces. Embryos and regenerating organs produce very complex, robust anatomical structures and stop growth and remodeling when those structures are complete. One of the most remarkable things about morphogenesis is that it is not simply a feed-forward emergent process, but one that has massive plasticity: even when disrupted by manipulations such as damage or changing the sizes of cells, the system often manages to achieve its morphogenetic goal. How do cell collectives know what to build and when to stop? Constructing and repairing anatomies in novel circumstances is a remarkable example of the collective intelligence of a biological swarm. I propose that a multi-scale competency architecture is how evolution exploits physics to achieve robust machines that solve novel problems. I will describe what is known about developmental bioelectricity — a precursor to neurobiology which is used for cognitive binding in biological collectives, that scales their intelligence and the size of the goals they can pursue. I will also discuss the cognitive light cone model, and conclude with examples of synthetic living machines — a new biorobotics platform that uses some of these ideas to build novel primitive intelligences. I will end by speculating about ethics, engineering, and life in a future that integrates deeply across biological and synthetic agents.

A team of researchers at Northwestern University has devised a new platform for gene editing that could inform the future application of a near-limitless library of CRISPR-based therapeutics.

Using chemical design and synthesis, the team brought together the Nobel-prize winning technology with therapeutic technology born in their own lab to overcome a critical limitation of CRISPR. Specifically, the groundbreaking work provides a system to deliver the cargo required for generating the gene editing machine known as CRISPR-Cas9. The team developed a way to transform the Cas-9 protein into a spherical nucleic acid (SNA) and load it with critical components as required to access a broad range of tissue and cell types, as well as the intracellular compartments required for gene editing.

This is not a knock on caffeine by any means. There’s a reason people have been consuming it for thousands of years. It works by blocking the neurotransmitters in the brain that produce drowsiness. This keeps your neurons firing at full speed, which makes you feel awake. And studies show it is very effective at boosting mood. But what if you could do more for your brain than simply tricking it into being awake? What if you could give your brain nutrients that help it work better all the time? Well, with a well-designed nootropics supplement, you can.

Nootropics are often marketed as “smart drugs,” which gives the impression that they’re going to boost your IQ and turn you into a rocket scientist or brain surgeon. But that is not actually the case. Nootropics are simply chemical compounds that help create the biological conditions necessary for optimal brain function. They include things like amino acids, vitamins, minerals, nutrients, and even stimulants such as caffeine. Some of these compounds serve as fuel for cognition. Others modulate various processes involved in neurotransmission.

An international research team led by the Department of Microstructured Quantum Matter at the MPSD reports the first observation of switchable chiral transport in a structurally achiral crystal, the Kagome superconductor CsV₃Sb₅. Their work has been published in Nature.

Whether or not an object is indistinguishable from its mirror image has important consequences for its physical behavior. Say you watch a basketball player in a mirror. The ball, the player and their surroundings are, at first glance, just the same in the mirror as in real life. But if observed closely, some details are different. The ball in the player’s right hand now appears in their left hand in the mirror. While the mirror image still shows the same hand, it has clearly changed from a left to a right hand or vice versa. Many other physical objects also have mirror images that differ in a key aspect, just like hands, which is why scientists call them handed or chiral (from Greek χϵρι = hand). Others, like the ball, cannot be distinguished from their mirror image, which makes them achiral.

Chirality is one of the most fundamental geometric properties and plays a special role in biology, chemistry and physics. It can cause surprising effects: One version of the carvone molecule, for example, produces a spearmint smell but its chiral—mirrored—equivalent smells of caraway.

Scientists have successfully increased the lifespan of animals and there are first studies which describe how we might reverse aging. So how could we one day rever aging?

From raspberry notes to rum and nail polish ones. Some call it a ‘space party,’ while others say ‘it stinks.’

Doctoral researcher in Astrobiology and professional perfumer, Marina Barcenilla, creates the scents of space based on astrochemistry and reports by astronauts.

Interesting Engineering (IE) report on the range of smells available including which represent the entire journey around Earth’s orbit to the center of the Milky Way. By tapping into the intimate relationship between olfaction (the sense of smell) and memory, the project aims to break communication barriers between science and the public.

The star exploded in an epic supernova, and its debris still shapes the chemical makeup of a distant quasar, a new study reports.

Researchers have developed an automatic drawing machine that uses pens and pencils to draw metamaterials onto paper. They demonstrated the new approach by using it to make three metamaterials that can be used to manipulate the microwave region of the electromagnetic spectrum.

Metamaterials are artificially engineered composite materials that derive their properties from patterned microstructures, rather than the chemical composition of the materials themselves. The exact shape, geometry, size, orientation and arrangement of the structures can be used to manipulate electromagnetic waves in ways that aren’t possible with conventional materials.

“Metamaterials, especially those used as absorbers, generally need to be thin, lightweight, wide and strong, but it isn’t easy to create thin and lightweight devices using traditional substrates,” said research team leader Junming Zhao from Nanjing University in China. “Using paper as the substrate can help meet these requirements while also lending itself to metasurfaces that conform to a surface or that are mechanically reconfigurable.”

The University of Alicante Quantum Chemistry group has predicted and published the existence of a new natural phenomenon in matter-radiation interaction, which has recently been experimentally confirmed. This finding is the subject of the review that the group’s researcher Juan Carlos Sancho García has submitted to the journal Nature, having been invited to publish in its “News & Views” section.

According to Sancho, his contribution is a successful example of how theory and simulation make it possible to advance and predict phenomena that are later confirmed by experiments, with the corresponding possible impact on the technological advances that populate society and the world today. In particular, the review reports the empirical confirmation of a prediction previously made and published by the UA team using quantum mechanics calculations. This is based on the effect of the “electronic correlation” that occurs strongly in this type of molecules studied, by which it is possible to take advantage of 100% of the energy that is emitted in the form of visible light on any screen.

The researcher explains that each of the pixels of a screen that makes up any device such as mobile phones, tablets, etc. is made up of molecules that emit the three basic colors (red, green, and blue). The battery activates these molecules to emit light (electroluminescence) so that they first reach their maximum level of “excitation” and then decay, and it is this loss of energy that results in the emission of color.
