Human Females Menstruate to Eliminate Unviable Fetuses

From a female perspective, pregnancy is always a huge investment. Even more so if her species has a hemochorial placenta. Once that placenta is in place, she not only loses full control of her own hormones, she also risks hemorrhage when it comes out. So it makes sense that females want to screen embryos very, very carefully. Going through pregnancy with a weak, inviable or even sub-par fetus isn't worth it. That's where the endometrium comes in. You've probably read about how the endometriu...

 Attention Capitalism

As someone who works in tech, I like the analogy of a DoS attack. The root of the issue is attention capitalism. Our attention is essentially a resource being exploited for profit. In that scenario, we're effectivley no longer in control of our own free will as long as someone else can profit by controlling it. On an individual scale, we can give it relatively benign labels like "distraction". But when you look at it from macro scale it's effectively a DDoS attack on our free will perpetrated...

 Knowledge Replaced with Social Media

When it emerged towards the end of the 80s as a purely text-based medium, [the internet] was seen as a tool to pursue knowledge, not pleasure. Reason and thought were most valued in this garden—all derived from the project of Enlightenment. Universities around the world were among the first to connect to this new medium, which hosted discussion groups, informative personal or group blogs, electronic magazines, and academic mailing lists and forums. It was an intellectual project, not about ...

 Flow Promotes Learning

Experiences that are well aligned with flow are those that we have no trouble committing to for a long time. We concentrate on them for hours at a time because we’re getting rewarded for that concentration. Even more important, perhaps, is that when we’re playing games, we want to enter that deep state of concentration. Well-crafted experiences offer a deep and effortless involvement that separates the experience of play from the experience of ordinary life. These experiences are enjoyabl...

 What We Learn from Games

What also went unremarked was how much I was learning by playing these games: basic ideas such as taking turns and developing patience while others completed their turns, the strengthening of simple memory, improved physical coordination, an ability to recognize and act on patterns, the capacity to see what might happen in a few turns if I took one move as opposed to another, resilience when losing, and the kind of strategic thinking that emerges once you realize that Scrabble is both a game ...

 How Scientific Thought Differs from Ancient Thought

If we consent for the time being to denude the mind of philosophical and metaphysical presuppositions, and take the matter in the most simple and naive way possible, I think our answer, stated in technical terms, will be that [science] substitutes data for objects. (It is not meant that this outcome is the whole effect of the experimental method; that as we saw at the outset is complex; but that the first effect as far as stripping away qualities is concerned is of this nature.) That Greek sc...

 Standing Desks Improve Student Engagement

The research looked at the results of an experiment in which 282 participants in grades 2-4 were observed in the fall and spring during one school year. Student engagement was monitored by actions such as answering a question, raising a hand, or participating in discussion, while off-task behaviors included talking out of turn. Engagement of the "treatment" classrooms was compared with the engagement of "control" classrooms. The researchers noted that both groups showed "general increases in...

 Apple is Not the Alternative Choice

For some reason Apple is still considered the liberal/counter-cultural choice but if you think about every dystopian novel/movie and then I said “there’s going to be a company, the world’s largest company (or thereabouts), they’re going to sell one product (basically - the difference between an iphone/ipad/macbook/apple watch is just the form factor) that everyone has to accept as is, and people will line up for days for that one product, missing work to get it, you will have no contr...

 Outside Context Problem

The usual example given to illustrate an Outside Context Problem was imagining you were a tribe on a largish, fertile island; you'd tamed the land, invented the wheel or writing or whatever, the neighbors were cooperative or enslaved but at any rate peaceful and you were busy raising temples to yourself with all the excess productive capacity you had, you were in a position of near-absolute power and control which your hallowed ancestors could hardly have dreamed of and the whole situation wa...

 NBIC: Nano-Bio-Info-Cogno

There's no one silver bullet technology that's going to make us all into superbeings. The trick is in the mix of different technologies. NBIC stands for nanotechnology, biotechnology, information technology, and cognitive science. Look at it this way: with nanotechnology and biotechnology, we stand to gain control over inorganic and organic matter. With advanced information technology, we get not just the horrendous data glut that's now tormenting us (and our National Security Agency), but d...
