Friston is Freudian

by The Neurocritic in The Neurocritic

Professor Karl Friston is one of the most prominent (and prolific) researchers in the field of neuroimaging. His contributions to methodological development in functional magnetic resonance imaging (fMRI) are immense:He invented statistical parametric mapping; SPM is an international standard for analysing imaging data and rests on the general linear model and random field theory (developed with Keith Worsley). In 1994, his group developed voxel-based morphometry. VBM detects differences in n........ Read more »

Galaxies are slowly running out of gas

by Charles Daney in Science and Reason

Galaxies are made of stars, and stars are made of... gas. So a large part of understanding how galaxies evolve and grow is understanding how much "gas" (literally, not "gasoline") is present in galaxies – but has not yet been incorporated in stars – at different periods in the history of the universe.What periods of the universe are most interesting in this regard? The answer is: periods somewhat less than the first half of the universe's existence since the time of the big bang, rou........ Read more »

You know your ‘type’? It’s stress dependent…

by aimee in misc.ience

A number of interesting revelations to be had here, and all to do with our choices of ‘mate’.

And by mate, I don’t mean the antipodean colloquialism meaning ‘friend’.  Nope, I mean mate as in, you know, someone you want to shag.  As it were.
The first revelation in this paper* is that, for the most part, [...]

The Conservative View of Progress in Applied Cancer Research

by Reason in Fight Aging!

Via FuturePundit, I see that a recent open access paper outlines the results of applied cancer research over the past four decades. Declining Death Rates Reflect Progress against Cancer The success of the "war on cancer" initiated in 1971 continues to be debated, with trends in cancer mortality variably presented as evidence of progress or failure. We examined temporal trends in death rates from all-cancer and the 19 most common cancers in the United States from 1970-2006. ... Progress in reduci........ Read more »

A hierarchical framework for assessing environmental impacts of dam operation

by JL in Analyze Everything

The effects of impoundments are big one for people working in aquatic ecosystems. In Kansas, a large number of dams are still being built (and a lot more are in the discussion stages). So I am constantly trying to understand more about the effects of dams and the impacts they have on upstream and downstream aquatic ecosystems. I was recently forwarded the an article by Burke, Jorde and ... Read more »

It’s Official – Fathers ARE Important to their Childrens’ Upbringing

by Isabelle Winder in Going Ape

David Cameron’s “Broken Britain”, with its image of moral decay driven by the breakdown in family life and poverty, may be inciting a lot of debate in parliament and the public press, but to read many studies of human evolution, you might be mistaken for thinking that the human male has never actually played a meaningful role in childcare. Most evolutionary studies focus on female life history – age at first reproduction, number of offspring and interbirth interval, for example – to th........ Read more »

When You Expect Rapid Feedback, the Fire to Perform Gets Hotter

by David DiSalvo in Neuronarrative

Let’s say that you’re preparing for an extremely important test that you and roughly 100 other classmates will be taking in a week. A few days before the test, you find out that your instructor will be going on a trip not long after the test is over and will be providing written and verbal feedback to the students within a day of the test.

This is unusual, because ordinarily the instructor waits a week or more before providing feedback. About half of the class finds out that the........ Read more »

Norovirus and Clinical Research

by Lab Rat in Lab Rat

I've written a lot about bacteria and plants over the last few weeks, so in celebration of the fact that my project is finally on it's way out (with a whimper rather than a bang, unfortunately, but that's how it goes sometimes) I've decided to descend into the world of viruses. I've also decided to have a go at deconstructing some clinical papers, to make a change from academia. The difference between clinical and academic research can probably be described as follows (and I'm pretty sure I've s........ Read more »

The phrenologist’s guide to ecological competence

by Katie Kline in EcoTone

Since Darwin, scientists have been theorizing as to why there is variation in brain size between species and individuals. Does a larger brain, in say humans, indicate advanced cognitive abilities and complex language processing? Or is a smaller brain, such as the Olive-backed thrush’s, adapted to weigh less to accommodate lengthy flights?

In psychology, the field of phrenology has generally been dissolved, and with it, the idea that variations in brain size could indicate differences ........ Read more »

Science in Russia

by Olexandr Isayev in olexandrisayev.com

Ever since the Soviet Union fell apart in 1991, Russian leaders have been vowing to transform their old-line, industrial society into a modern, knowledge-based economy driven by innovative science and technology. The current Russian president, Dmitry Medvedev, has repeated that ambition frequently — not least as a way to overcome Russia’s dependence on oil and [...]... Read more »

Coca-Cola and Water Use in India: "Good Till the Last Drop"

by Eric Michael Johnson in The Primate Diaries

                 Coca-Cola sucks India dry.      Image: Carlos Latuff / Wikimedia CommonsThe marketing executive who came up with Coca-Cola's popular slogan in 1908 most likely never expected it would be taken so literally. However, a hundred years ago there probably weren't many who imagined a term like "water wars" could exist in a region that experiences annual monsoons.

Trusting and Bargaining in Africa

by Simon Halliday in Amanuensis

Are we Africans different to the rest of the world in our giving, punishing and trusting behaviour? Three remarkable economic anthropology studies try to examine this kind of question with several ethnic groups in four countries: the Pimbwe, Sukuma and Kahama in Tanzania, the Maasai of Kenya and the Ju/'hoan Bushmen of Namibia and Botswana. I can't to do any of the papers justice with my short comments, but I thought you might find them interesting nevertheless.The three papers take quite diffe........ Read more »
