A very seductive hypothesis: did Cambridge Analytica use its psychographics profiles to find the audience for our post-truth world? Did they target gullible voters on behalf of Trump’s campaign? Why is a Cambridge Analytica employee reading about the Need for Cognition Scale?

In a remarkable paper (summarised here), Fording and Schram analysed some survey results from January 2016 and highlighted the disproportionate support for Trump among “low-information voters”. They define those as voters who either score low in political knowledge or low on the so-called Need for Cognition Scale. The latter criterion means that they tend to make decisions based on heuristics rather than by thinking through the issue methodically. Of course, the two factors correlate: if you don’t think much about politics, you are unlikely to know a lot about it and vice-versa.[1]

Fording and Schram went on to assess the preference for Trump or Clinton segmented through those criteria. Because the data was collected in January, this is not expressed as a vote preference, but as a “warmth index” (or a difference of warmth), in the Y-axis.

There’s an old saying in neuroscience: “neurons that fire together wire together.” This means the more you run a neuro-circuit in your brain, the stronger that circuit becomes. This is why, to quote another old saw, “practice makes perfect”. The more you practice piano, or speaking a language, or juggling, the stronger those circuits get.

Scientists have known this for years. However, nowadays researchers learn another part of the truth: In order to learn something, even more important than practicing is the ability to unlearn, or to break down the old neural connections. This is called “synaptic pruning”.

Wonder how much this would be really true.

What would happen if everyone in the world had an IQ score over 200 points? This is a type of intelligence that only comes along every so often. An IQ level of 200 is as high, or higher, than the theoretical IQs of history’s greatest minds like Albert Einstein, Leonardo da Vinci, and Isaac Newton.

In recent research published in the journal Molecular Psychiatry, Northwestern Medicine scientists identified a new pathway in the brain that can be manipulated to alleviate depression.

The pathway offers a promising new target for developing a drug that could be effective in individuals for whom other antidepressants have failed.

New antidepressant options are important because a significant number of patients don’t adequately improve with currently available antidepressant drugs.

Slime mold, a unicellular organism living in forest litter, offers a curious case of learning without a brain. This blob-like creeping organism learns from experience and imparts the knowledge to peers.

Federal agencies of the US government are expanding their calls for quantum computing resistant encryption methods. In effect, the National Institute of Standards (NIST) recently announced a request for public-key post-quantum algorithms. This action follows warnings from the National Security Agency (NSA) about the risks of potential quantum-based cyberattacks and the NSA’s appeal for developing post-quantum algorithms.

Moreover, in the near future, it might possible for anyone to manipulate the awesome power of quantum computing. The astronomical price of a quantum computer would not be a limitation because, for example, IBM is offering to the general public quantum computing via the cloud.

For the first time since the advent of stem cell therapy, a team of scientists from the North Carolina State University, the University of North Carolina at Chapel Hill and First Affiliated Hospital of Zhengzhou University, was able to implant synthetic cardiac stem cells which effectively repaired muscle tissue that got damaged by a heart attack. Typically, heart muscles that get scarred from a heart attack will either stay as is or get worse, but not improve. With the synthetic stem cell implant done, however, the result was a remarkable contradiction. Details about this new technique that is supposedly less risky than traditional stem cell procedures were recently published in the ‘Nature Communications’ journal.

Stem cell therapy works by helping damaged tissue repair itself. Although this type of treatment can be effective, it comes with certain types of risks, most notably, immune system rejection and cancerous growths. And, the process itself is very delicate because natural stem cells are quite fragile, have to be stored carefully, and must undergo a series of typing and matching prior to being used.

It is these limitations that have prompted scientists to come up with a different approach to make stem cell therapy work better. And what they developed was a procedure involving synthetic stem cells.

Older than Sumerian script? The Danube Valley civilization is one of the oldest civilizations known in Europe. It existed from between 5,500 and 3,500 BC in the Balkans and covered a vast area, in what is now Northern Greece to Slovakia (South to North), and Croatia to Romania (West to East).

During the height of the Danube Valley civilization, it played an important role in south-eastern Europe through the development of copper tools, a writing system, advanced architecture, including two storey houses, and the construction of furniture, such as chairs and tables, all of which occurred while most of Europe was in the middle of the Stone Age. They developed skills such as spinning, weaving, leather processing, clothes manufacturing, and manipulated wood, clay and stone and they invented the wheel. They had an economic, religious and social structure.
