#1 Smash Hit in AI 2020: AI Cracks Protein Folding!

The reason it became possible, of course, is many years of human creativity

Our Walter Bradley Center director Robert J. Marks is back with the second instalment of 2020 smash hits in AI—and now, the #1 Smash Hit! Readers may recall that we offered a fun series during the holidays about the oopses and ums and ers in the discipline (typically hyped by uncritical sources). This time, Dr. Marks talks with Jonathan Bartlett and Eric Holloway about AI programs that can beat humans at understanding the complexities of protein folding, the immensely complex ways that proteins in our bodies actually work. Robert J. Marks: AI has cracked a problem that stumped biologists for 50 years. And it’s a huge deal. Jonathan and Eric, elaborate on this a little bit. Jonathan Bartlett: Well, protein…

#3 AI Smash Hits 2020: AI Can Help Paralyzed People Move Again

The human brain can interface directly with electronics

Our Walter Bradley Center director, Robert J. Marks, is back with the second instalment of the 2020 Smash Hits in AI. Readers may recall that we offered a fun series during the holidays about the oopses and ums and ers in the discipline (typically hyped by uncritical sources). This time, Dr. Marks talks with Eric Holloway about ways AI can help people with disabilities. A major, often unrealized, fact is that the human brain can work directly with electronic devices, provided that they are positioned or implanted so as to interface with neurons. Many possibilities are being explored. And the “exoskeleton” is our #3.

#4 AI Smash Hits 2020 AI Helps Detect Dreaded White Eye Disease

The first step in treatment is correct diagnosis

Our Walter Bradley Center director Robert J. Marks is back with the second instalment of 2020 smash hits in AI. Readers may recall that we offered a fun series during the holidays about the oopses and ums and ers in the discipline (typically hyped by uncritical sources). This time, Dr. Marks wants to talk about a serious issue: The use of AI apps developed at his university, Baylor in Texas, to detect “white eye,” an eyeball cancer in children. “White eye” or leukocoria can be caused by a number of conditions, many of which are treatable. In some cases, however, it is a form of cancer (retinoblastoma). Our story begins at 14:32: https://episodes.castos.com/mindmatters/Mind-Matters-117-Eric-Holloway-Jonathan-Bartlett.mp3 Robert J. Marks: Now, the story behind…

Can Religion Improve a Person’s Mental Health?

That’s a big claim but there is considerable evidence for it. The question is, what does the evidence mean?

In 2020, a year when Americans’ perception of their own mental health dropped significantly, we are told that Gallup reported: The only demographic subgroup who didn’t report a decline were those who attend religious services weekly. That group showed an increase of 4 percent compared to 2019. Joe Carter, “New Study: Frequent Churchgoers Have Better Mental Health” at Gospel Coalition Carter cites several sources arguing for the benefits of religion but, in truth, it’s not really a new idea. Religion gives people something to believe in, provides a sense of structure and typically offers a group of people to connect with over similar beliefs. These facets can have a large positive impact on mental health—research suggests that religiosity reduces suicide…

The British Medical Journal’s Top Picks in Offbeat Medical Science

In its legendary Christmas edition, the Journal highlights interesting findings that are often junk science

The British Medical Journal (BMJ) is one of the world’s oldest and most prestigious medical journals. Each Christmas, they take time off from the usual dry academic papers and publish studies that are noteworthy for their originality: “We don’t want to publish anything that resembles anything we’ve published before.” Although the papers are unusual, BMJ’s editors state that: While the subject matter may be more light-hearted, research papers in the Christmas issue adhere to the same high standards of novelty, methodological rigour, reporting transparency, and readability as apply in the regular issue. Christmas papers are subject to the same competitive selection and peer review process as regular papers. The articles are often goofy, and four have won the dreaded satiric…

Did You Know You Have a Second Brain?

Our guts operate on a quite separate nervous system. Learning more will help control gastrointestinal diseases

Our huge gastrointestinal tracts operate their own nervous system, using neurons that follow different principles from those of brain neurons, according to recent findings: Our approximately seven-meter long gastrointestinal (GI) tract has its own functionally distinct neurons. Since this enteric nervous system (ENS) operates autonomously, it is sometimes referred to as the “second” or “abdominal” brain. While the ENS controls muscle movement (peristalsis) in the gut and its fluid balance and blood flow, it also communicates with the immune system and microbiome. Karolinska Institutet, “New fundamental knowledge of the ‘abdominal brain’” at Medical Xpress (December 7, 2020) Paper. (subscription required) The Karolinska researchers made progress in studying the little-understood second brain by mapping the neuron types in the digestive systems…

Why Robotics Offers Hope for Paraplegics

The breakthrough idea is that the human brain can process electronic signals from machines as well as signals from peripheral nerves

Neuroengineer Gordon Cheng compares technology that can help paraplegics to walk again to learning to drive a car: The idea behind this is that the coupling between the brain and the machine should work in a way where the brain thinks of the machine as an extension of the body. Let’s take driving as an example. While driving a car, you don’t think about your moves, do you? But we still don’t know how this really works. My theory is that the brain somehow adapts to the car as if it is a part of the body. With this general idea in mind, it would be great to have an exoskeleton that would be embraced by the brain in the…

AlphaFold Scores Huge Breakthrough in Analyzing Causes of Disease

In a world so deeply designed and complexly organized, we need a quick and practical way of knowing what was going on in cells and viruses. AI can help

Alphabet’s DeepMind team has just scored a breakthrough in finding treatments for diseases. Their latest AlphaFold system won a grand challenge in analyzing the “folds” of proteins. Proteins—large and often very complex chains of amino acids—do the work in our cells. But, like all bodies, they are three-dimensional. We can’t understand them until we can analyze the folds (the third dimension) that are unique to each type among hundreds of thousands. Knowing what a given protein actually does (or doesn’t) is critical to developing many new medical treatments. How hard is the problem? In his acceptance speech for the 1972 Nobel Prize in Chemistry, Christian Anfinsen famously postulated that, in theory, a protein’s amino acid sequence should fully determine its…

Neuroscientist: Your Brain Isn’t for Thinking, Just Surviving

Lisa Feldman Barrett hopes that her materialist perspective will help us deal with our current anxieties

Last Sunday, we featured the views of philosopher Samir Chopra, who argues that anxiety, while distressing, is a normal outcome of our human ability to see the past and the future as well as the present. A pig gets anxious when he sees that his trough is empty. But he cannot, by nature, know that he is destined for the menu at a local fast food place, let alone that all his kin have gone that way. Knowing the past and sensing the future opens up both great powers and vast avenues of anxiety for a human mind. But, in an op-ed in the New York Times, psychologist and neuroscientist Lisa Feldman Barrett (pictured), the author of Seven and a…

AI Is Not Nearly Smart Enough to Morph Into the Terminator

Computer engineering prof Robert J. Marks offers some illustrations in an ITIF think tank interview

In a recent podcast, Walter Bradley Center director Robert J. Marks spoke with Robert D.Atkinson and Jackie Whisman at the prominent AI think tank, Information Technology and Innovation Foundation, about his recent book, The Case for Killer Robots—a plea for American military brass to see that AI is an inevitable part of modern defense strategies, to be managed rather than avoided. It may be downloaded free here. In this second part ( here’s Part 1), the discussion (starts at 6:31) turned to what might happen if AI goes “rogue.” The three parties agreed that AI isn’t nearly smart enough to turn into the Terminator: Jackie Whisman: Well, opponents of so-called killer robots, of course argue that the technologies can’t be…

Is Mindfulness Losing Its “Shine” These Days?

Maybe, but that’s because it has often been misused. Rightly understood, it’s a blessing

In a recent news release from the University of Buffalo, we learn that mindfulness (meditation and similar practices) were not found to be helpful in managing stress at the time it is happening: Where earlier work in this area suggests how mindfulness may help people manage active stressors, the current paper finds evidence for an opposite response. In the midst of stress, mindful participants demonstrated cardiovascular responses consistent with greater care and engagement. Put another way, they actually were “sweating the small stuff.” Bert Gambini, “Be mindful: Study shows mindfulness might not work as you expect” at University of Buffalo However, the study, which measured the cardiovascular stress response of 1001 volunteers also found, Even more curiously, although the study’s…

Why Did New York Have COVID Policy That Killed Elderly Patients?

For all practical purposes, the government directive was essentially an order to spread COVID to people in nursing homes

This is a difficult post to write, and a difficult post to read. I’ve thought about it for months, and what I’m going to say must be said. I see no way around the conclusions I’ll draw. So here goes. On March 25, 2020, during the height of the COVID-19 pandemic in New York State, the New York State Department of Health, under the signatures of Governor Andrew Cuomo, DOH Commissioner Howard Zucker, and Executive Deputy Commissioner Sally Dreslin, issued a directive to New York State nursing homes requiring nursing homes to accept patients for re-admission or admission regardless of their COVID-19 status. The salient paragraph is: No resident shall be denied re-admission or admission to the NH solely based…

Did Social Media Panic Drive Up the Damage from COVID-19?

Richards: It was, honestly, terrifying to watch important stories and studies get buried in real time on Google searches.

Last month, business studies prof Jay Richards, along with co-authors Douglas Axe and William M. Briggs, published a book with some controversial premises: One of them is that many popular COVID-19 fears are the overblown outcome of paying too much attention to social media as opposed to the facts that got lost in the uproar. And that we are paying the price now in human, as well as financial, costs. The Price of Panic: How the Tyranny of Experts Turned a Pandemic into a Catastrophe (October 2020) assembles a massive statistical case. But in this interview with Mind Matters News, Richards focuses on how it affected us: What we all thought was happening and why we thought so—a different story…

Can a Pill Change Your Mind About Basic Issues in Life?

The legalization of mind-altering drugs raises the question in the research community

An Oxford researcher into psychedelics thinks so. Eddie Jacobs offers a disturbing premise, “What if a pill can change your politics or religious beliefs?” The background is that some jurisdictions are contemplating licencing the otherwise illegal psychedelic psilocybin (“magic mushrooms”) in the near future as a treatment for depression. He writes, How would you feel about a new therapy for your chronic pain, which—although far more effective than any available alternative—might also change your religious beliefs? Or a treatment for lymphoma that brings one in three patients into remission, but also made them more likely to vote for your least preferred political party?

Cancer Maps—An Expensive Source of Phantom Patterns?

Is the money the U.S. government spends on tracking cancer patterns a good investment? There’s a way we can tell

The U.S. government puts interactive maps on the internet that show the geographic incidence (all the way down to census blocks) of various types of cancer. Millions of dollars are spent each year maintaining these maps, but for what purpose? The problem with cancer maps is that they tempt the curious and fearful to scrutinize the brightly colored chunks, thinking that any patterns they discover must be meaningful. However, statistical patterns are sometimes meaningless. For example, I flipped a coin ten times and got these results: There is a cluster of 3 heads in a row and a cluster of 4 tails in a row: These clusters are not at all surprising. If a fair coin is flipped ten times,…

COVID-19 Response Exposes Racism in China, amid Harmony Claims

The lid blew off when African leaders broke the accustomed silence imposed by their dependence on Chinese high-tech loans

The coronavirus COVID-19 epidemic has exposed two longstanding ugly problems: underlying racist views of Africans living in China and the burden debt to China lays on several African countries. The key flashpoints creating tension between China and Africa are 1) Mistreatment of citizens of African countries living in China, particularly in Guangzhou, capital of Guangdong province (pictured) and 2) Beijing’s position on granting debt relief to countries in Africa so they can direct resources to dealing with the coronavirus. In one incident, Nigeria’s speaker of the House of Representatives, Femi Gbajabiamila, posted a video of himself summoning Chinese Ambassador Zhou Pingjian to his office where he expressed his displeasure about a Nigerian man being evicted from his home. While nobody…

Why, as a Neurosurgeon, I Believe in Free Will

The spiritual aspect of the human soul, sadly, leaves its signature in epilepsy

In his classic book, Mystery of the Mind, (1975) epilepsy surgery pioneer Dr. Wilder Penfield, asked a significant question: “Why are there no intellectual seizures?” Epileptic seizures can be experienced in a variety of ways—convulsions of the whole body, slight twitching of a muscle, compulsive memories, emotions, perceptions of smells or flashes of light, complex motor behaviors such as chewing or laughing or even walking, or subtle moments of inattention. But seizures never have intellectual content. There are no intellectual seizures, which is odd, given that large regions of the brain are presumed by neuroscientists to serve intellectual thought. It is all the more remarkable when we consider that seizures commonly originate in these “intellectual” areas of the brain. Yet…

If AlphaFold Is a Product of Design, Maybe Our Bodies Are Too

The deeper we go into science, the more important our unique human contributions become

Recently, we’ve been looking at tech philosopher George Gilder’s new Gaming AI about what AI can—and can’t—do for us. It can’t do our thinking for us but it can do many jobs we don’t even try because no human being has enough time or patience to motor through all the calculations. Which brings us to the massive complexity of the proteins that carry out our genetic instructions—better knowledge of which would help us battle many diseases. Gilder notes that when DeepMind’s AlphaGo beat humans at the board game Go in 2016, it wasn’t just for the fun of winning a game. DeepMind cofounder Demis Hassabis (pictured in 2018) is more interested in real-life uses such as medical research (p. 11).…
