Landau on the second law

by Ponder Stibbons in The truth makes me fret.

I was browsing through a collection of Landau’s papers and came across one of the more bizarre explanations of the second law of thermodynamics that I’ve seen. The few people who frequent this blog probably don’t need this explained to them, but the reason why many philosophers think that the second law needs ‘explaining’ is [...]... Read more »

Is Mr. S more flexible than Sci? Cognitive flexibility and first-person shooter games.

by Evil Monkey in Neurotopia

This post comes to you courtesy, actually, of Sci-Dad, who sent an email to Sci saying wasn't this cool. Sci then showed it to Mr. SiT, and he was very intrigued, and insisted she cover it. Sci kind of wanted to make cake balls. Maybe that will be tomorrow.

Sustainable de-growth: a new paradigm for meeting environmental goals

by Paul Spraycar in Beyond Climate Change

For those who have run out of patience for the promised benefits of ‘sustainable development,’ there is a new alternative paradigm: sustainable de-growth.The objective of sustainable de-growth is characterized by “an equitable and democratic transition to a smaller economy with less production and consumption,” with the goal of creating a “society built on quality rather than on quantity, on cooperation rather than on competition.”The authors of a new paper in Ecological Economics la........

H5N1, the bird flu: the virus

by Atila Iamarino in Influenza A (H1N1) Blog – English

In the last text, it was discussed the capacity of H5N1 of infecting a number of hosts and causing very harsh symptoms, causing deaths in over 50% of the recorded human cases. Despite this, its transmission from person to person seems to be well limited. Now we will see its characteristics that contribute to this.
As [...]... Read more »

Species area curves & neutral theory

by Thomas Kluyver in Thomas' Plant-Related Blog

How many species are there here? It’s a beguilingly simple question, and a fundamental area of interest. A moments thought shows that the bigger here is, the more species there will be. So, if we start from a little patch of my lawn, and take successively larger heres until we’ve included the whole world, we [...]... Read more »

Atlatls to Bows: A Serendipitous Lion Hunt

by teofilo in Gambler's House

Like atlatls, but to an even greater degree, bows are rare in the archaeological record because they were made of perishable materials.  While some types of atlatls had more durable attachments such as hooks and weights, bows were almost always made of wood and various fibrous materials, except in some areas where they were made [...]...

Of Bears, Berries, and Hoofed Invaders

What did your mommy and daddy believe?

by Tom Rees in Epiphenom

Young adults in the USA are more likely than ever before to tell pollsters that they don't see themselves as 'being' of any particular religion - they are unaffiliated. The data are clear, but the reason for this shift is not.

It might simply be their age. Maybe they will be more likely to identify with a religion when they're older. Alternatively, there could be an uptick in the numbers of people who are leaving religion - for good.

Or maybe it's a snowball effect. More than ever before, Amer........ Read more »

Trick of the Light – Optical Illusions Can’t be Beat

You know ‘em, you love ‘em: Suddenly, pictures bulge out in three dimensions, or static dots begin to swirl, or you see colors that aren’t really there.

Genetics & the Jewish Question

by Razib Khan in Gene Expression

The 2,000 year dance between the Jewish people and Western civilization has spawned many questions of scholarly interest. A relatively minor point, though not trivial, has been the issue of the biological relatedness of the Jewish people, and their relatedness to the nations among whom they were resident. This particular point became more starkly relevant [...]... Read more »

Inappropriate citations?

by Christina Pikas in Christina's LIS Rant

Kevin Zelnio of Deep Sea News tweeted the title of this piece and sent my mind going over the various theories of citation, what citations mean, studies showing how people cite without reading (pdf) (or at least propagate obvious citation errors), and also how people use things but don't cite them in certain fields... I was also thinking, I know what inappropriate touching is, but what's inappropriate citing?  So let's take a look at the article: Todd, P., Guest, J., Lu, J., & Chou, L........ Read more »

Monoamine Shock

by Neuroskeptic in Neuroskeptic

Electroconvulsive therapy (ECT) is a crude but effective treatment for depression. It consists of applying a brief alternating current to the brain in order to induce a generalized seizure, which usually lasts for less than half a minute. It looks nothing like the picture to the left.ECT is typically given three times per week, and a dozen sessions are enough to produce a dramatic improvement in depression in most cases. However, how it works is entirely mysterious. There are plenty of theories......... Read more »
