Steven Kotler: Besides neuroanatomical changes in flow there are neurochemical changes, right. The brain produces a giant cascade of neurochemistry. You get norepinephrine, dopamine, anandamide, serotonin and endorphins. All five of these are performance enhancing neurochemicals, right. So they make you faster, stronger, quicker and they do the same thing with your brain. In the front end of a flow state you take in more information, you process it more deeply meaning you process it using more parts of your brain and you process it more quickly. There’s some debate about this but it does appear that you process it more quickly. This is norepinephrine and dopamine. So when people enter a flow state they talk about feeling like they’re senses are incredibly heightened. This is the performance enhancing aspect of norepinephrine and dopamine.
Where these chemicals really come in handy is how they affect motivation, creativity and learning. We’ll start with motivation. Besides being performance enhancing chemicals these are obviously all feel good drugs, right. These five chemicals are the most potent feel good drugs the brain can produce. As a result flow is considered the most addictive state on earth. Scientists don’t like the word addictive so instead they use autotelic. When something is autotelic it is an end in itself. What it means is that once an experience starts producing flow we will go extraordinarily far out of our way to get more of it which is why researchers now believe flow is the source code of intrinsic motivation. Another thing that those neurochemicals do is they augment the creative process. So creativity is always recombinantory. It’s the product of novel information, bumping into old thoughts to create something startlingly new. So if you want to amplify creativity, you want to amplify every aspect of that process. Again, the neurochemicals help. So on the front end of the flow state when you get norepinephrine and dopamine they’re tightening focus so you are taking in more information per second. So you are boosting that part of the creative process. Norepinephrine and dopamine do something else in the brain which is they lower signal to noise ratio so you detect more patterns. They jack up pattern recognition so our ability to link ideas together is also an enhancer. Taking in more information we can link it together.
Anandamide which is another chemical that shows up in flow doesn’t just promote pattern recognition. It promotes lateral thinking. So pattern recognition is more or less the linking of familiar ideas together. Lateral thinking is the linking of very disparate ideas together, right. So more information per second, all kinds of pattern recognition, lateral thinking. All of it surrounds the creative process and amplifies all of it which is why, for example, studies run by my organization, the Flow Genome Project, we found creativity is increased 500 to 700 percent. To give you another example in a recent Australian study they took 42 people, gave them a very tricky brainteaser to solve, the kind that needs very creative problem solving. Nobody could solve the problem. They induced flow artificially using transcranial magnetic stimulation to basically knock out the prefrontal cortex. They induced artificial transient hypofrontality technically.
As a result, 23 people solved the problem in record time. So massively amplified motivation, massively amplified creativity. The last thing flow does that’s really important is it jacks up learning. So a quick shorthand for how learning works is the more neurochemicals that show up during experience, the better chance that experience has of moving from short term holding into long term storage, right. Neurochemicals among their many other functions, one of them is to tag experiences. Big neon sign saying really important, save for later because flow is this giant neurochemical dump. It massively amplifies learning. So in studies run by DARPA and researchers at Advanced Brain Monitoring in California, when they introduced flow artificially this time kind of using neurofeedback in soldiers, marksmen to be exact, they found that soldiers in flow learn to shoot 230 percent faster than normal. When they redid this study using novice marksmen, they did it with riflemen and archers, what they discovered is that the period of time it takes to train a novice archer or novice marksman up to the expert level when they’re in flow can be cut in half. So Malcolm Gladwell’s famous 10,000 hours to mastery, what the research shows is that flow cuts it in half.

If machines develop consciousness, or if we manage to give it to them, the human-robot dynamic will forever be different.
- Does AI—and, more specifically, conscious AI—deserve moral rights? In this thought exploration, evolutionary biologist Richard Dawkins, ethics and tech professor Joanna Bryson, philosopher and cognitive scientist Susan Schneider, physicist Max Tegmark, philosopher Peter Singer, and bioethicist Glenn Cohen all weigh in on the question of AI rights.
- Given the grave tragedy of slavery throughout human history, philosophers and technologists must answer this question ahead of technological development to avoid humanity creating a slave class of conscious beings.
- One potential safeguard against that? Regulation. Once we define the context in which AI requires rights, the simplest solution may be to not build that thing.
Duke University researchers might have solved a half-century old problem.
- Duke University researchers created a hydrogel that appears to be as strong and flexible as human cartilage.
- The blend of three polymers provides enough flexibility and durability to mimic the knee.
- The next step is to test this hydrogel in sheep; human use can take at least three years.
Duke researchers have developed the first gel-based synthetic cartilage with the strength of the real thing. A quarter-sized disc of the material can withstand the weight of a 100-pound kettlebell without tearing or losing its shape.

What would it be like to experience the 4th dimension?
Physicists have understood at least theoretically, that there may be higher dimensions, besides our normal three. The first clue came in 1905 when Einstein developed his theory of special relativity. Of course, by dimensions we’re talking about length, width, and height. Generally speaking, when we talk about a fourth dimension, it’s considered space-time. But here, physicists mean a spatial dimension beyond the normal three, not a parallel universe, as such dimensions are mistaken for in popular sci-fi shows.
An algorithm may allow doctors to assess PTSD candidates for early intervention after traumatic ER visits.
- 10-15% of people visiting emergency rooms eventually develop symptoms of long-lasting PTSD.
- Early treatment is available but there's been no way to tell who needs it.
- Using clinical data already being collected, machine learning can identify who's at risk.
The psychological scars a traumatic experience can leave behind may have a more profound effect on a person than the original traumatic experience. Long after an acute emergency is resolved, victims of post-traumatic stress disorder (PTSD) continue to suffer its consequences.
In the U.S. some 30 million patients are annually treated in emergency departments (EDs) for a range of traumatic injuries. Add to that urgent admissions to the ED with the onset of COVID-19 symptoms. Health experts predict that some 10 percent to 15 percent of these people will develop long-lasting PTSD within a year of the initial incident. While there are interventions that can help individuals avoid PTSD, there's been no reliable way to identify those most likely to need it.
That may now have changed. A multi-disciplinary team of researchers has developed a method for predicting who is most likely to develop PTSD after a traumatic emergency-room experience. Their study is published in the journal Nature Medicine.
70 data points and machine learning

Study lead author Katharina Schultebraucks of Columbia University's Department Vagelos College of Physicians and Surgeons says:
"For many trauma patients, the ED visit is often their sole contact with the health care system. The time immediately after a traumatic injury is a critical window for identifying people at risk for PTSD and arranging appropriate follow-up treatment. The earlier we can treat those at risk, the better the likely outcomes."
The new PTSD test uses machine learning and 70 clinical data points plus a clinical stress-level assessment to develop a PTSD score for an individual that identifies their risk of acquiring the condition.
Among the 70 data points are stress hormone levels, inflammatory signals, high blood pressure, and an anxiety-level assessment. Says Schultebraucks, "We selected measures that are routinely collected in the ED and logged in the electronic medical record, plus answers to a few short questions about the psychological stress response. The idea was to create a tool that would be universally available and would add little burden to ED personnel."
Researchers used data from adult trauma survivors in Atlanta, Georgia (377 individuals) and New York City (221 individuals) to test their system.
Of this cohort, 90 percent of those predicted to be at high risk developed long-lasting PTSD symptoms within a year of the initial traumatic event — just 5 percent of people who never developed PTSD symptoms had been erroneously identified as being at risk.
On the other side of the coin, 29 percent of individuals were 'false negatives," tagged by the algorithm as not being at risk of PTSD, but then developing symptoms.

Schultebraucks looks forward to more testing as the researchers continue to refine their algorithm and to instill confidence in the approach among ED clinicians: "Because previous models for predicting PTSD risk have not been validated in independent samples like our model, they haven't been adopted in clinical practice." She expects that, "Testing and validation of our model in larger samples will be necessary for the algorithm to be ready-to-use in the general population."
"Currently only 7% of level-1 trauma centers routinely screen for PTSD," notes Schultebraucks. "We hope that the algorithm will provide ED clinicians with a rapid, automatic readout that they could use for discharge planning and the prevention of PTSD." She envisions the algorithm being implemented in the future as a feature of electronic medical records.
The researchers also plan to test their algorithm at predicting PTSD in people whose traumatic experiences come in the form of health events such as heart attacks and strokes, as opposed to visits to the emergency department.
