Always a Bigger Fish Part 1 – Dogfish as Predators

by Chuck in Ya Like Dags?

I’ve found myself with some breathing room between grading my students and studying for my own exams, so it’s time to write up a post I’ve been thinking about for a while.  I’ve been wanting to do a quick summary … Continue reading →... Read more »

Psycasm - Half Full, or Half Empty? Well, That Depends on the Shape of the Glass.

Science and Hype – Arsenic Life?

by Paul Vallett in Electron Cafe

One of the things that inspired me to write a blog about science is that I believe science does not have to be “dumbed down” for everyone to think that it is interesting. Researchers shouldn’t be afraid to use clear and understandable language to explain what is interesting about their results. Sometimes scientists (and science [...]... Read more »

[guest post: Alex Bradley, PhD] Arsenate-based DNA: a big idea with big holes

by Kevin Bonham in Food Matters

In the wake of the NASA excitement over the new arsenic study, and my promise to give a detailed review of the paper itself, I have recruited a colleague with strong opinons about the work, a solid chemistry and microbiology background, and "Dr." in front of his name to share his analysis. I will be posting my personal and less-technical take on the whole thing soon, so stay tuned.

Dr. Alex Bradley uses modern geochemistry and microbiology tools to study the evolution of life and Earth. He........ Read more »

Acupuncture, some dodgy maths and a cracking review paper

by Lorimer Moseley in BodyInMind

I have a challenge for you. Imagine you’re in ancient China and you’ve had this idea that health and disease hang on the flow of energy through invisible energy pathways called meridians that can be manipulated by applying needles in certain specific points. How do you go about systematically validating this theory? How do you [...]... Read more »

How do you spell "success" after bariatric surgery?

by Maureen McCormick in GourMind

The sweet smell of "success" . . . it's so intangible, so personal, so dependent on the point of view. Here's a sampling of what I have heard from patients:"I can buy clothes in a regular department store!"Often after years of buying shapeless clothes in specialty stores, many people - women and men! - enjoy trying on clothes in a department store, feeling stylish and reveling in colors other than black."I don't need a seat belt extender on airplanes anymore! And I actually fit into the seat ........ Read more »

Bilingual Brains: Reading in Hebrew and in English

by Jason Goldman in The Thoughtful Animal



I've got an article that appeared in this week's Jewish Journal of Greater Los Angeles about recent research from Hadassah University on the neurobiology of bilingual (English-Hebrew) reading.

Is the English-reading brain somehow different from the Hebrew-reading brain? You might not expect any major differences; after all, both languages are alphabetic and are read more or less phonetically by breaking words into their constituent sounds. Compare English and Hebrew to a logographic language........ Read more »

Are we ‘illiterate listeners’?

by Henkjan Honing in Music Matters

'French babies cry differently as compared to German babies. This was the conclusion from a study that was published a year ago in Current Biology (see earlier entry). Three day old German babies cry in a downward fashion, their French contemporaries showed an increasing swelling of the cry and stop abruptly. It was a surprising observation, especially in the light of the general belief that in crying the pitch should always drop as a physiological consequence of the respiratory cycle. Apparentl........

searching for wormholes with general relativity

When you’re reading sci-fi stories in which some of the characters find themselves in need to cover hundreds or thousands of light years very quickly without a warp drive, they manage to make it through time and space via a convenient wormhole.

Debates on Emotions II

Ekman (1994), influenced by Darwin (1872/1997) and his mentor Tomkins(1962/2008), classified the characteristics of basic emotions, which distinguishthem from one another and other affective phenomena as follows: (1) Distinctiveuniversal signals (facial expression); (2) Presence in other primates; (3)Distinctive physiology (such as a specific ANS reaction for each emotion); (4)Distinctive universal antecedents – there are certain stimuli, preprogrammedevolutionarily, that will elicit each of t........

Gay Men Take Drugs to Fit In

by Ultimo167 in Strong Silent Types

It is widely assumed that gay men take more drugs and have more sex than their straight counterparts have, but the motivation behind such enhanced behaviours tends to veer toward psychopathological explanations. Could it really be that simple? Ueno (2010) argues for greater contemplation.... Read more »

Arsenic-associated bacteria (NASA's claims)

by Rosie Redfield in RRResearch

Here's a detailed review of the new paper from NASA claiming to have isolated a bacterium that substitutes arsenic for phosphorus on its macromolecules and metabolites.  (Wolfe-Simon et al. 2010, A Bacterium That Can Grow by Using Arsenic Instead of Phosphorus.)  NASA's shameful analysis of the alleged bacteria in the Mars meteorite made me very suspicious of their microbiology, an attitude that's only strengthened by my reading of this paper.  Basically, it don........

The emotional problems of the slightly religious

by Tom Rees in Epiphenom

It's generally taken as fact that religion is linked to happiness - happier people are more likely to be religious,  if you take into account other circumstances. There are loads of studies, of varying quality, that support this idea.

However, most people who interpret these data make a couple of assumptions that are probably not valid. Firstly, the assume that they can be generalised across cultures. However most studies are  done in the USA, where being non-religious often leads to ........ Read more »

Walsby's Square Archaea! Haloquadratum walsbyi

Procrastination and overwhelming itch to get back to blogging win over the more pressing obligations tonight. Fuck'em, it's Friday night, I can write about protists if I feel like it.
