Lieutenant-Colonel Patterson, the Lunatic Line and the Lions

by Sam W in From C to Carnivore

This is the second instalment of “Proud & Majestic” but another title fit better and it stands proudly and majestically on it’s own. In this post, I want to tell you a story. Indeed, it is one of the best stories because it is true (and artistic licence is obvious and mine and mine alone). [...]... Read more »

Sticky spots and Big Brother – Studying skin cells in the lab

by Cancer Research UK in Cancer Research UK - Science Update

Our bodies are made of millions upon millions of tiny cells. One of the biggest challenges for researchers studying cancer is to find out what individual cells are doing as they change from a healthy state to a cancerous one. But many lab techniques only give an overview of a large population of cells, either [...]... Read more »

Article Review: Evaluating students using RIME method

by Michelle Lin in Academic Life In Emergency Medicine

How do evaluate medical students and residents, who are rotating through your Emergency Department? Do you have a structured framework for assessing their competencies?Have you heard of the RIME method of evaluating learners on their clinical rotation? Dr. Lou Pangaro (Vice Chair for Educational Programs in the Dept of Medicine at the Uniformed Services University) published a landmark article in 1999 on his simple yet effective approach in evaluating medical students and residents. I had the pl........ Read more »

Hitting the gym harder for a decade won't do a thing for your weight.

I would have had the headline read, "Exercising exercise's confirmation bias" but figured that wouldn't be as grabby.From the only publishable because the world has such a huge crush on exercise impacting on weight file comes the, Effect of change in physical activity on body fatness over a 10-y period in the Doetinchem Cohort Study published ahead of print in the American Journal of Clinical Nutrition.The study is just one of many in a long string of studies that fail to show any dramatic benef........

How hunger affects our financial risk taking

by BPS Research Digest in BPS Research Digest

The hungrier an animal becomes, the more risks it's prepared to take in the search for food. Now, for the first time, Mkael Symmonds and colleagues have shown that our animal instinct to maintain a balanced metabolic state influences our decision-making in other contexts, including finance.

Nineteen male participants performed the same gambling task on three occasions, a week apart: either after a fourteen hour fast; immediately after eating a standard two-thousand calorie meal; or one hour aft........ Read more »

From Soy Feminizing to “Soy Fabulous”

by Erin McMichael in Woo Fighters

Here’s a mini run-down of the woo-logic that is to follow, straight from the self-proclaimed soyologist, Jim Rutz:

Soy is very popular today.
When soy is consumed, estrogen rises within your system.
Elevated estrogen levels feminize you.
Gay men are feminine.
Pregnant women who eat a surplus of soy are feminizing their male fetuses.
Male babies who admit to being gay later in life that are born from soy-eating mamas need to realize that it was from the soy.
The rise of homosexuality is du........ Read more »

AstroInformatics II: From public outreach to public engagement

Outreach and education are two areas that stand to gain from developments in semantic astronomy and an increased scientific presence on the web. Big changes have already taken place, driven by a community eager to connect and communicate about the research we do every day. As part of a panel at the AstroInformatics 2010 conference [...]...

#evol2010 day 2: In which sexes diverge and reptiles are disparate

by Jeremy Yoder in Denim and Tweed

In day two, Evolution 2010 is already feeling a mite overwhelming. I started the morning in the SSE symposium on speciation and the origin of dimorphism, then spent the rest of the day bouncing from talk to talk and preparing for my own presentation, which is tomorrow at 9:30. I'm going to bed early tonight, I think.

There's a new daily wrap-up podcast over at Evolution, Development, and Genomics, and, if you haven't been following the conference on Twitter, check hashtag #evol2010 or this list........ Read more »

Rheumatoid Arthritis and the Cell Cycle

by Evil Monkey in Neurotopia

This is a paper in which Sci has a certain amount of personal investment. You see, Sci has a family member who suffers from rheumatoid arthritis. And when I say suffer, I mean she suffers terribly. Rheumatoid arthritis is an autoimmune disease where you own body attacks the lining of the membranes between your joints. The result is painful swelling and stiffness (arthritis) which usually affects the smaller joints first (like your fingers) and which can severely impair your quality of life. ........ Read more »

Creativity and mental illness

by Charles Daney in Science and Reason

The association between creativity and mental illness is sort of a cliché – but that doesn't mean there's nothing to it. Standard examples given include Vincent van Gogh, Robert Lowell, and John Nash.There has been a rather large amount of research into the connection, and a large number of biographical accounts of famous creative people who also suffered from mental illness. But the neurobiological details are emerging only slowly. After all, our understanding of the biological roo........ Read more »

Plot Multiple Time Series using the flow/inkblot/river/ribbon/volcano/hourglass/area/whatchamacallit plots ~ blue whale catch per country w/ ggplot2

Ever since I first looked at this NYT visualization by Amanda Cox, I’ve always wanted to reproduce this in R. This is a plot that stacks multiple time series onto one another, with the width of the river/ribbon/hourglass representing the strength at each time. The NYT article used box office revenue as the width of the river. It’s also an interactive web app. thanks to some help from graphic designers.... Read more »

If you ostracise them, will they come?

by Tom Rees in Epiphenom

Humans, like all other primates, are obsessed by their peer group of colleagues and acquaintances. And that's for good reason because, for primates, being excluded from the group can be lethal.

So what do you do if you find yourself being ostracised? Well, for humans at least, one option is to turn to religion. Religion, after all, provides a ready-made community for those who conform to the group ideology – and even for those who don't, religion offers a virtual world of supernatural buddies........

Expecting back pain – the possibility of a self-fulfilling prophecy

It seems like years ago now, well, it is years ago now, that I did this study with The Walking Cortex (TWC, Paul Hodges).  This was one of my PhD studies.

How did the victims of the Plinean Eruption of Vesuvius die?

by Greg Laden in Greg Laden's Blog

Even at the most extreme edges of the flow of stuff out of the volcano Pompeii, at the far edge of the mud and ash that came from the volcano's explosion, the heat was sufficient to instantly kill everyone, even those inside their homes.

And that is how the people at Pompeii, who's remains were found trapped and partly preserved within ghostly body-shaped tombs within that pyroclastic flow, died. They did not suffocate. They did not get blown apart by force. They did not die of gas poisoning........ Read more »

Monkeys and Mice: A Literature Review the Anti-Vaccine Folks Should Embrace But Won't

by KWombles in Countering...

Aschner and Ceccatelli (2010) review the relevant data for thimerosal as a cause of autism. They conclude there is "no reliable data indicating that administration of vaccines containing thimerosal is a primary cause ofautism. However, one cannot rule out the possibility that the individual gene profile and/or gene–environmentinteractions may play a role in modulating the response to acquired risk by modifying the individual susceptibility."Aschner and Ceccatelli first discuss a........
