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

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 »

Are you scummy froth or riding the business waves?

by David Bradley in Sciencetext

It’s perhaps an obvious statement perhaps needing only one word to qualify it – successful business sells. As an allegedly going concern, if you’re not selling your products or services, then you’re not likely to remain viable for very long. It seems to be too easy for companies to be distracted from this mantra by [...]Post from: David Bradley's Sciencetext Tech TalkAre you scummy froth or riding the business waves?

Review of Towards pharmacogenomics knowledge discovery with the semantic web

by UUCJC in Uppsala University Cheminformatics Journal Club

The article, Towards pharmacogenomics knowledge discovery with the semantic web, written by Michael Dumontier and Natalia Villanueva-Rosales attempts to demonstrate the importance of pharmacogenomics and how the data should be structured in the best possible way. Their strategy towards knowledge discovery involves ontology design, population and question answering. In a more specific manner this was established with Web Ontology Language OWL-DL, Protégé and Manchester OWL Syntax.With the SO-Ph........ Read more »

"Why do we believe", and are atheists really more intelligent?

by Daniel in Ego sum Daniel editor Dave Munger has written an article for SEED magazine entitled "Why do we believe". The article summarizes recent blog entries regarding studies on the origins of religiosity. It's really worth reading to get a good overview of the subject, and what do you know he links my entry on god's will and beliefs in it.

Among the studies that are mentioned is a controversial study entitled "Why Liberals and Atheists Are More Intelligent" (link at the end of this post).

The Common Genetic Causes of Celiac Disease

Celiac disease is characterized by an immune response to glutin and similar proteins found in wheat, rye and barley. For individuals with celiac disease, eating glutin results in an inflammed small intestine, diarrhea and fatigue, among other symptoms. It’s estimated that about 1% of all Americans suffer from celiac disease. Given the heritability of [...]... Read more »

Fossil testate amoebae

by Psi Wavefunction in Skeptic Wonder

There's something about the idea of fossilised single-celled organisms that's just pure awesome. Even if it's just their shells.For example, take a look at these past relatives of Centropyxis and Leptochlamys from Schmidt et al. 2010 JEM, AOP:Testate amoebae from 100mya amber in France. The arrow in 1 points to what the authors believe may be fossilised cytoplasm flowing out of the cell. 2) four ventral pores visible. 4-7) holotype of modern Leptochlamys, optical sections. 8-11 potential resting........
