Super-Intelligent Humans Are Coming - Issue 18: Genius - Nautilus
"If only a small number of genes controlled cognition, then each of the gene variants should have altered IQ by a large chunk—about 15 points of variation between two individuals. But the largest effect size researchers have been able to detect thus far is less than a single point of IQ. Larger effect sizes would have been much easier to detect, but have not been seen."

Father of philosophy comes under forensic scrutiny
""Biographers have not described such symptoms in Rene Descartes, apart from one possible isolated episode of migraine with aura on the night of November 10 1619," characterised by sudden visual and auditory hallucinations, the letter in The Lancet said."

Woman of 24 found to have no cerebellum in her brain - health - 10 September 2014 - New Scientist
"Doctors did a CAT scan and immediately identified the source of the problem – her entire cerebellum was missing (see scan, below left). The space where it should be was empty of tissue. Instead it was filled with cerebrospinal fluid, which cushions the brain and provides defence against disease."

An Iron Curtain Has Descended Upon Psychopharmacology | Slate Star Codex
"Science, you would say, is science everywhere. You can’t have one set of elements in Russia and another in the US, everyone would work together and compare notes. At the very least one side would have the common decency to at least steal from the other. No way anything like this could possibly go on. But as far as I can tell this is exactly the state of modern psychopharmacology."

Ancient Man Used “Super-Acoustics” to Alter Consciousness (... and speak with the dead?)
"Sound in a Basso/Baritone range of 70 – 130 hz vibrates in a certain way as a natural phenomenon of the environment in the Hypogeum, as it does in Newgrange passage tomb, megalithic cairns and any stone cavity of the right dimensions. At these resonance frequencies, even small periodic driving forces can produce large amplitude oscillations, because the system stores vibrational energy. Echoes bounce off the hard surfaces and compound before they fade. Laboratory testing indicates that exposure to these particular resonant frequencies can have a physical effect on human brain activity."

Stanford researcher: Hallucinatory 'voices' shaped by local culture
"Stanford anthropologist Tanya Luhrmann found that voice-hearing experiences of people with serious psychotic disorders are shaped by local culture – in the United States, the voices are harsh and threatening; in Africa and India, they are more benign and playful. This may have clinical implications for how to treat people with schizophrenia, she suggests."

Accessories Keep Brains Safe From Mind-Reading Tech [Pics] - PSFK
"These couture adornments carry alert wearers to Neuro-Imaging Surveillance (NIS) scans. This technology, currently used for medical purposes, can scan the brain to see which portions are active, which may betray what a person is thinking or feeling."

The Serotonin Transporter Gene Alters Sensitivity to Attention Bias Modification: Evidence for a Plasticity Gene
Attention bias modification (ABM) procedures have been shown to modify biased attention with important implications for emotional vulnerability and resilience. The use of ABM to reduce potentially toxic biases, for instance, is a newly emerging therapy for anxiety disorders. A separate line of gene-by-environment interaction research proposes that many so-called vulnerability genes or risk alleles are better seen as plasticity genes, as they seem to make individuals more susceptible to environmental influences for better and for worse.

Against an Aesthetics of Noise (Ray Brassier interview)
"My conviction is that the sources and structures of human experience can and will be understood scientifically, but this integration of experience into the scientific worldview will entail a profound transformation in our understanding of what it means to be human — one as difficult for us to comprehend from within the purview of our current experience as the latter would have been for our hominid ancestors."

Manipulating morals: scientists target drugs that improve behaviour | Science | The Guardian
"A pill to enhance moral behaviour, a treatment for racist thoughts, a therapy to increase your empathy for people in other countries - these may sound like the stuff of science fiction but with medicine getting closer to altering our moral state, society should be preparing for the consequences, according to a book that reviews scientific developments in the field."
