Bacterial Growth Patterns Can Spell Out Our Inmost Thoughts

Biomedical engineers at Duke University have created an encoder/decoder using bacterial growth patterns. Because such growth patterns tend to be regular, they can be reduced to an encoding scheme they call “emorfi”: The encoding is not one-to-one, as the final simulated pattern corresponding to each letter is not exactly the same every time. However, the researchers discovered that a machine learning program could learn to distinguish between them to recognize the letter intended.

We’ve often written about electronic prostheses that link up with the human nervous system — which essentially means controlling the prosthesis by thoughts alone. A reversal is also possible, as the University of Washington demonstrated in 2020: A machine (the “Smellicopter”) used an insect’s antenna to identify and seek out smells: “Nature really blows our human-made odor sensors out of the water,” said lead author Melanie Anderson, a UW doctoral student in mechanical engineering. “By using an actual moth antenna with Smellicopter, we’re able to get the best of both worlds: the sensitivity of a biological organism on a robotic platform where we can control its motion.” Sarah McQuate, “The Smellicopter is an obstacle-avoiding drone that uses a live moth Read More ›

Recently, we looked at the question of whether human IQ could be artificially increased via genetic engineering. One proposal was to mass produce human embryos, implanting only the smart ones and discarding the rest. All other issues aside, it’s unclear how to determine which kids will turn out to be the smart ones. Now biochemist Michael Denton, author of a number of books including the recent Miracle of Man (2022), writes to tell us that the idea won’t work due to fundamental genetics. Noting that theoretical physicist Stephen Hsu, who advanced the idea of discarding embryos above, is not a medical geneticist, he told Mind Matters News, Its true there are many genes involved in brain development but most genes Read More ›

In a talk at the Dallas Conference on Science and Faith (2021), philosopher Steve Meyer looked at the question of whether a multiverse, as in Multiverse of Madness (2022), or God, as in many traditions is the origin of our universe. That is, is our universe designed — as considerable evidence suggests — or is ours just one of a few lucky universes whose extra-lucky conditions allow for advanced life? Dr. Meyer is the author of The Return of the God Hypothesis (Harper One, 2021) which argues that the evidence from science favors God over a multiverse. (Sample here.)

As noted recently at Scientific American, thinking about UFOs is no longer presumptive evidence of membership in the lunatic fringe: On June 9, with only a few hours’ notice, NASA held a press conference to announce a study it was commissioning on unidentified aerial phenomena (UAPs). The acronym is a rebranding of what are more popularly known as unidentified flying objects, or UFOs, a topic usually associated with purported extraterrestrial visitations and government conspiracy theories. The question on the public’s mind was why one of the U.S.’s premier scientific agencies was getting involved in something often considered to be at the farthest fringes of respectability.

At Big Think, we have been told by the managing editor, in a tone of considerable confidence: Because intelligence is such a strong genetic trait, rapidly advancing genetics research could result in the ability to create a class of super-intelligent humans one-thousand times higher in IQ than today’s most brilliant thinkers. Stephen Hsu, Vice-President for Research and Professor of Theoretical Physics at Michigan State University, believes we are only a decade away from identifying the many thousands of genetic variants that control for intelligence. These variants, called alleles, could then be selected for by the parents of a soon-to-be-conceived child, and possibly genetic engineering could be done on adults to boost their intelligence.

The fact that octopuses are unusually intelligent (like mammals) — even though they are solitary invertebrates — means that they now receive some protection against cruelty. Protection that no one bothers about for, say, clams and oysters. But the science puzzle remains. How did octopuses and some of their close kin among the cephalopods get so smart? Theories about how mammals and birds got to be smart may not work here. A recent paper adds a little more information to the controversy. Studying the common octopus and the California octopus, researchers found that the same “jumping genes” are active in the octopus brain as in the human one — even though the two types of brain are very different.

As biologist John Timmer notes at Ars Technica, some life forms appear much more intelligent than others despite having brains of roughly the same size: Animals with very different brains from ours—a species of octopus and various birds—engage with tools, to give just one example. It seems intuitive that a brain needs a certain level of size and sophistication to enable intelligence. But figuring out why some species seem to have intelligence while closely related ones don’t has proven difficult—so difficult that we don’t really understand it.

In whatever galaxy you happen to find yourself, you take the circumference of a circle, divide it by its diameter, measure closely enough, and uncover a miracle — another circle, drawn kilometers downstream of the decimal point. There would be richer messages farther in. It doesn’t matter what you look like, or what you’re made of, or where you come from.

Here is some of his evidence that “only a special type of unique being very close to our own biological design could have taken the first and vital step to technological enlightenment, fire-making”: From first principles, a creature capable of creating and controlling fire must be an aerobic terrestrial air-breathing species, living in an atmosphere enriched in oxygen, supportive of both respiration and combustion.

In his famous Weasel program zoologist and philosopher Richard Dawkins shows that the simple combination of random mutation and natural selection (Darwinian evolution) can produce the English sentence, “Methinks it is like a weasel”, in a short time period. The point of his program is to demonstrate that evolution can generate the complex, pre-specified DNA sequences we find in biology before the heat death of the universe. His argument sounds persuasive because both English sentences and DNA sequences are made up of symbols. Both can be randomly modified anywhere, and by cumulative selection, they can plausibly adapt to the environment in reasonably short order. Writers in English can learn to pen best-selling novels through trial and error and audience feedback. Read More ›

Although there isn’t a precise definition of “civilization,” we usually associate it with a species capable of altering its physical environment on a regional or even planetary scale. How would we know, millions of years later, that they had been here?

Among these were, in America, giant ground sloths weighing 4 tons, a giant armadillo weighing a ton, and mastodons; in Australia the marsupial diprotodon weighing a ton, giant kangaroos, and a marsupial ‘lion’; and in Eurasia giant deer, woolly rhinoceros, mammoth, and giant elephants weighing up to Read More ›

Octopuses, squid, and cuttlefish are among the smartest invertebrates, rivalling mammals for complex behavior that can include delaying gratification, having good memories (even in old age), and getting emotional about pain. Yet they are related to life forms like the nautilus which displays few such qualities. Looking to solve the mystery, researchers began to examine the genomes of the two-spot octopus, the Boston Market squid, and the Hawaiian bobtail squid. And that’s where they discovered something interesting. Squid genomes were arranged differently from those of similar life forms.: Compared to genomes from some of their mollusk kin, the coleoid cephalopods’ genomes are very divergent, says [Oleg] Simakov. “You have this mosaic of chromosomes, where ancestral chromosomes were broken up and Read More ›

On the one hand, the National Academy of Sciences has said that we may communicate with extraterrestrial intelligences during our lifetimes. On the other hand, Italian physicist Enrico Fermi (1901–1954) asked, “Where are they?” (the Fermi Paradox). A new study suggests that the natural development of civilizations may be to blame: In the hopes of answering this question, a new paper published on May 4 in the journal Royal Society Open Science claims that “civilizations either collapse from burnout or redirect themselves to prioritizing homeostasis, a state where cosmic expansion is no longer a goal, making them difficult to detect remotely.” “Either outcome — homeostatic awakening or civilization collapse — would be consistent with the observed absence of [galactic-wide] civilizations.” Read More ›

One of them, he guesses, is bilateral symmetry (life forms whose left and right sides are mirror images): “symmetry requires less information for DNA to encode and allows more flexibility to develop future traits that may be advantageous.” He also notes that smart life forms tend to be mobile rather than stationary: “We don’t know of any intelligent plants or fungi, for the simple reason that stationary things don’t have to be smart.” Well, wait.

One genuine surprise in recent decades has been the discovery that plants have nervous systems like animals and use some of the same compounds in communications — for example, TMAO to relieve stress and glutamate to speed transmission. Biologist Peter Rogers pointed out recently that the similarities may shed a bit of light on issues around anaesthesia. Surprisingly, it is possible to anesthetize a plant. The shameplant (Mimosa pudica) and the Venus flytrap demonstrated that: Thirty years after anesthesia debuted in the operating room, Claude Bernard, a French physiologist, demonstrated that the shameplant (Mimosa pudica), which bashfully folds into itself when touched, was unresponsive to touch after exposure to ether, a commonly used anesthetic.
