MIT alumnus and entrepreneur Ben Vigoda took his probability-processing technology to market with help from the Institute.

 

Helping computers navigate ambiguity

Vigoda’s group is creating computer chips that perform inferences and machine learning on uncertain data — data that can be incomplete or contradictory — more efficiently than today’s chips. 

“If a normal computer program receives an unanticipated or noisy input, it will ordinarily either give the user an error message, crash the program or even, in some rare cases, crash the machine,” Vigoda says. “With probabilistic processing, the hope is to help the computer directly understand that the world is noisy, ambiguous, or even contradictory, and to be able to cope with that in a more native way.”

Sharrock's insight:
Science tests for causality to separate it from correlation. It also refines understanding of systems in order to measure natural indicators. We know this from physician practice of measuring heart beats, blood pressure, temperature but by also checking ears, nose, and throat. Teachers can discuss how certain fish health can tell a great deal about the ocean's "health" as a system.

Cellular forces and matrix assembly coordinate fibrous tissue repair : Nature Communications : Nature Publishing Group

Cellular forces and matrix assembly coordinate fibrous tissue repair : Nature Communications : Nature Publishing Group | Science, Technology, and Current Futurism | Scoop.it
Planar in vitro models have been invaluable tools to identify the mechanical basis of wound closure. Although these models may recapitulate closure dynamics of epithelial cell sheets, they fail to capture how a wounded fibrous tissue rebuilds its 3D architecture. Here we develop a 3D biomimetic model for soft tissue repair and demonstrate that fibroblasts ensconced in a collagen matrix rapidly close microsurgically induced defects within 24 h. Traction force microscopy and time-lapse imaging reveal that closure of gaps begins with contractility-mediated whole-tissue deformations. Subsequently, tangentially migrating fibroblasts along the wound edge tow and assemble a progressively thickening fibronectin template inside the gap that provide the substrate for cells to complete closure. Unlike previously reported mechanisms based on lamellipodial protrusions and purse-string contraction, our data reveal a mode of stromal closure in which coordination of tissue-scale deformations, matrix assembly and cell migration act together to restore 3D tissue architecture.

B Vitamins and the Brain: Mechanisms, Dose and Efficacy—A Review

B Vitamins and the Brain: Mechanisms, Dose and Efficacy—A Review | Science, Technology, and Current Futurism | Scoop.it
The B-vitamins comprise a group of eight water soluble vitamins that perform essential, closely inter-related roles in cellular functioning, acting as co-enzymes in a vast array of catabolic and anabolic enzymatic reactions. Their collective effects are particularly prevalent to numerous aspects of brain function, including energy production, DNA/RNA synthesis/repair, genomic and non-genomic methylation, and the synthesis of numerous neurochemicals and signaling molecules. However, human epidemiological and controlled trial investigations, and the resultant scientific commentary, have focused almost exclusively on the small sub-set of vitamins (B9/B12/B6) that are the most prominent (but not the exclusive) B-vitamins involved in homocysteine metabolism. Scant regard has been paid to the other B vitamins. This review describes the closely inter-related functions of the eight B-vitamins and marshals evidence suggesting that adequate levels of all members of this group of micronutrients are essential for optimal physiological and neurological functioning. Furthermore, evidence from human research clearly shows both that a significant proportion of the populations of developed countries suffer from deficiencies or insufficiencies in one or more of this group of vitamins, and that, in the absence of an optimal diet, administration of the entire B-vitamin group, rather than a small sub-set, at doses greatly in excess of the current governmental recommendations, would be a rational approach for preserving brain health.

The Hidden Epidemic Of Doctor Suicides

The Hidden Epidemic Of Doctor Suicides | Science, Technology, and Current Futurism | Scoop.it
One of the biggest problems reformers like Wible face is the fact that health care professionals have been aware of the anomalously high suicide rate in their field for a long time. Every once in a while, a medical journal or a trade publication will run an article about the problem. It’s not unknown.

Robert P. Bright and Lois Krahn of the Mayo Clinic sum up the problem as follows:

Physicians have a much higher rate of suicide than the general population, but are less likely to seek treatment because of fears of losing their licenses or being thrown out of medical school, fear of losing patients if word gets out they are seeking mental health treatment, or simply not having time to seek treatment due to their workloads.

average I.Q.’s have been rising steadily for a century as access to schooling and technology expands, a phenomenon known as the Flynn Effect. As Jaeggi and others see it, the genetic component of intelligence is undeniable, but it functions less like the genes that control for eye color and more like the complex of interacting genes that affect weight and height (both of which have also been rising, on average, for decades). “We know that height is heavily genetically determined,” Jonides told me during our meeting at the University of Michigan. “But we also know there are powerful environmental influences on height, like nutrition. So the fact that intelligence is partly heritable doesn’t mean you can’t modify it.”

"Since the first record of a tumor in ancient Egypt to the modern use of targeted cancer treatments, we’ve learned a great deal about cancer — how it spreads, how it resists, and how it’s defeated — but we’ve also learned a lot about ourselves and the strength of human resilience."

Deep Learning Is Going to Teach Us All the Lesson of Our Lives: Jobs Are for Machines — Basic income — Medium

Deep Learning Is Going to Teach Us All the Lesson of Our Lives: Jobs Are for Machines - Basic income - Medium

Next generation artificial intelligence " in combination with robots like Boston Dynamics’ next generation Atlas portends, is a world where machines can do all four types of jobs and that means serious societal reconsiderations. If a machine can do a job instead of a human, should any human be forced at the threat of destitution to perform that job? Should income itself remain coupled to employment, such that having a job is the only way to obtain income, when jobs for many are entirely unobtainable? If machines are performing an increasing percentage of our jobs for us, and not getting paid to do them, where does that money go instead? And what does it no longer buy? Is it even possible that many of the jobs we’re creating don’t need to exist at all, and only do because of the incomes they provide? These are questions we need to start asking, and fast.

Transcript of "A robot that runs and swims like a salamander" | Science, Technology, and Current Futurism | Scoop.it
TED Talk Subtitles and Transcript: Roboticist Auke Ijspeert designs biorobots, machines modeled after real animals that are capable of handling complex terrain and would appear at home in the pages of a sci-fi novel. The process of creating these robots leads to better automata that can be used for fieldwork, service, and search and rescue. But these robots don't just mimic the natural world -- they help us understand our own biology better, unlocking previously unknown secrets of the spinal cord.
Sharrock's insight:
The four components information is fascinating. It's not what we were taught about the spinal cord when I was a kid, that there is more going on in the spine than just "reflexes": 
"There are four main components behind animal locomotion. The first component is just the body, and in fact we should never underestimate to what extent the biomechanics already simplify locomotion in animals. Then you have the spinal cord, and in the spinal cord you find reflexes, multiple reflexes that create a sensorimotor coordination loop between neural activity in the spinal cord and mechanical activity. A third component are central pattern generators. These are very interesting circuits in the spinal cord of vertebrate animals that can generate, by themselves, very coordinated rhythmic patterns of activity while receiving only very simple input signals. And these input signals coming from descending modulation from higher parts of the brain, like the motor cortex, the cerebellum, the basal ganglia, will all modulate activity of the spinal cord while we do locomotion. But what's interesting is to what extent just a low-level component, the spinal cord, together with the body, already solve a big part of the locomotion problem. You probably know it by the fact that you can cut the head off a chicken, it can still run for a while, showing that just the lower part, spinal cord and body, already solve a big part of locomotion."

Saliency, switching, attention and control: a network model of insula function

Saliency, switching, attention and control: a network model of insula function | Science, Technology, and Current Futurism | Scoop.it

The insula is a brain structure implicated in disparate cognitive, affective, and regulatory functions, including interoceptive awareness, emotional responses, and empathic processes. While classically considered a limbic region, recent evidence from network analysis suggests a critical role for the insula, particularly the anterior division, in high-level cognitive control and attentional processes. The crucial insight and view we present here is of the anterior insula as an integral hub in mediating dynamic interactions between other large-scale brain networks involved in externally oriented attention and internally oriented or self-related cognition. The model we present postulates that the insula is sensitive to salient events, and that its core function is to mark such events for additional processing and initiate appropriate control signals. The anterior insula and the anterior cingulate cortex form a “salience network” that functions to segregate the most relevant among internal and extrapersonal stimuli in order to guide behavior. Within the framework of our network model, the disparate functions ascribed to the insula can be conceptualized by a few basic mechanisms: (1) bottom–up detection of salient events, (2) switching between other large-scale networks to facilitate access to attention and working memory resources when a salient event is detected, (3) interaction of the anterior and posterior insula to modulate autonomic reactivity to salient stimuli, and (4) strong functional coupling with the anterior cingulate cortex that facilitates rapid access to the motor system. In this manner, with the insula as its integral hub, the salience network assists target brain regions in the generation of appropriate behavioral responses to salient stimuli. We suggest that this framework provides a parsimonious account of insula function in neurotypical adults, and may provide novel insights into the neural basis of disorders of affective and social cognition.

Viral Video Showing Sun’s “Vortex” Motion Is Wildly Inaccurate

Viral Video Showing Sun’s “Vortex” Motion Is Wildly Inaccurate | Science, Technology, and Current Futurism | Scoop.it
I’ve been getting lots of tweets and email from folks linking to a slick-looking video, a computer animation showing the motion of the planets around the Sun as the Sun orbits around the Milky Way Galaxy. It’s a very pretty video with compelling music and well-done graphics. It’s wrong. And not just superficially; it’s deeply wrong, based on a very wrong premise. While there are some useful visualizations in it, I caution people to take it with a galaxy-sized grain of salt.
Sharrock's insight:
excerpt: "how things should be and how they are don’t always overlap. The Universe is a pretty cool place, and works using a fairly well-regulated set of rules. We call those rules physics, they’re written in the language of math, and trying to understand all that is science."

Can social science still be used as a foundation for public policy? On improving the reliability of evidence. | Science, Technology, and Current Futurism | Scoop.it
If ‘boring’ negative findings are less likely to be published, the evidence base becomes dominated by positive results. This creates a serious problem for a policymaker trying to assess the scientific evidence on any given topic. They will end up getting a highly distorted picture of the real world; one in which the extent and severity of social problems is probably exaggerated, as is the extent to which policy interventions can change things. This might leave policymakers too active in public policy investing in potentially ineffective solutions to social problems that might not even exist.

Posttraumatic stress disorder reveals imbalance between signalling systems in the brain

Posttraumatic stress disorder reveals imbalance between signalling systems in the brain | Science, Technology, and Current Futurism | Scoop.it
It has previously been shown that people with PTSD have altered brain anatomy and function. A new study by researchers from the Department of Psychology at Uppsala University and Clinical Neuroscience at Karolinska Institutet shows that people with PTSD have an imbalance between two neurochemical signalling systems of the brain, serotonin and substance P.
Sharrock's insight:

Interesting research support that experiences can significantly change brain. 

 

"The study, which has been published in the renowned scientific journal Molecular Psychiatry, shows that it is the imbalance between the two signalling systems which determines the severity of the symptoms suffered by the individual rather than the degree of change in a single system. Others have previously speculated that the biological basis of psychiatric disorders such as PTSD includes a shift in the balance between different signalling systems in the brain but none has yet proved it. The results of the study are a great leap forward in our understanding of PTSD. It will contribute new knowledge which can be used to design improved treatments for traumatised individuals."
