Natural selection has altered the appearance of Europeans over the past 5,000 years. Anthropologists at Johannes Gutenberg University Mainz and geneticists at University College London, working in collaboration with archaeologists from Berlin and Kiev, have analyzed ancient DNA from skeletons and found that selection has had a significant effect on the human genome even in the past 5,000 years, resulting in sustained changes to the appearance of people.

The Brain: How The Brain Rewires Itself. It was a fairly modest experiment, as these things go, with volunteers trooping into the lab at Harvard Medical School to learn and practice a little five-finger piano exercise.

The Brain: How The Brain Rewires Itself

Neuroscientist Alvaro Pascual-Leone instructed the members of one group to play as fluidly as they could, trying to keep to the metronome's 60 beats per minute. Every day for five days, the volunteers practiced for two hours. Then they took a test. Does the internet promote fairness of income distribution? (w/ Video)

(Phys.org) —The question of how an economic system should be structured in order to best promote fairness and equality is one of the most debated subjects of all time.

Does the internet promote fairness of income distribution? (w/ Video)

By approaching the complexities of this question from the field of network science, researchers from MIT and other institutions have found that the average degree to which individuals in a society are connected to each other can crucially affect the fairness of income distribution. The researchers, J. Borondo, et al., have published a paper on their research in a recent issue of Scientific Reports. In their study, the researchers constructed a model in which individuals can earn income in two ways: by producing content or by distributing the content produced by others. A system in which more income is earned by production than by distribution is labeled as meritocratic, while one in which more income is earned by distribution is called topocratic. Anti-protest law changes Twitter users' behavior, but not network structure, physicists show.

(Phys.org) —With the rise of social media, it is possible to organize public demonstrations on larger scales and in less time than ever before.

In response, some governments are trying to decide how to regulate and impede the organization of these demonstrations, in order to maintain safety, order, or for other reasons. But very little is known about exactly how repressive legislation affects social media networks and their users. New research now suggests that social networks may be surprisingly resistant to such legislation. The Brain: How The Brain Rewires Itself. The Brain: How The Brain Rewires Itself. Core Components. Facebook. Untangling Liberalism and Libertarianism. Liberalism and libertarianism share a root word as well as a common history, but today liberals and libertarians are often far apart on economic and political issues, especially in the US.

Untangling Liberalism and Libertarianism

I’ll try to get to the bottom of the current divisions, giving due respect to the self-serving talking points repeated by each side, which is to say no respect at all to what partisan liberals and libertarians pretend to believe. I’m more interested in the principles that can be deduced from what such partisans say or that are indicated by their political actions. The principles I detect are rather shocking. Rants Within the Undead God. Dateline: NEW YORK—A team of doctors from the Columbia Medical Center succeeded in generating new human hair growth, which promises a cure for baldness.

“We’re within sight of the cure,” said one of the lead scientists. Rants Within the Undead God. Psychiatry, Anxiety Disorders, and Existential Angst. Is there a relationship between clinical anxiety and existential angst?

Psychiatry, Anxiety Disorders, and Existential Angst

If so, what existential role do psychiatrists play in treating anxiety disorders? I’ll address these and related questions in what follows. Anxiety Disorders.

(Kaiser Family Foundation) Making long-term memories in minutes: a spaced learning pattern from memory research in education. Introduction Memory systems select from the thousands of stimuli in the environment those to encode permanently. Scientists have tried to understand long-term memory (LTM) processes through a variety of approaches including using repeated, spaced stimuli (Ebbinghaus, 1913; Pavlov, 2010).
