Availability decay of Bioinformatics web resources : Yes widgets can change it

by Abhishek Tiwari in Fisheye Perspective

Quality and availability of bioinformatics resources is always a matter of great debate. HTTP 404 not found is quite frequent phenomenon for bioinformatics researchers looking to use some published web accessible database or analysis tool. A 4-year follow-up survey on the lack of persistence of bioinformatics resources was published in year 2008 by Jonathan D. [...]... Read more »

From Conducting Polimers to First Organic Superconductors

by Olexandr Isayev in olexandrisayev.com

This week, I returned from the historic 50th Sanibel Symposium. Over 350 chemists and physicists gathered together to celebrate half-centennial success of quantum and computational chemistry. One lecture that caught my attention was a plenary talk “Conducting Polymers: a saga of more than 50 years” by professor Jean-Marie Andre. Professor Andre emphasized a role [...]... Read more »

Ooze like an amoeba, float like a bird - wish we could still do that when stressed!

by Student @ Fresno State in Darwin's Bulldogs


Here's another fun weird science story from NPR, about a creature that might be in the dirt in your own backyard:

Naegleria gruberi grows a pair of flagella when under stress. But unlike a sperm tail, it puts these appendages out front, and swims by breast stroke. The organism is stained to emphasize its anatomy.

Preparedness: Bioterrorism

by C. Julian in The Swarm


Last post I briefly typed about Ebola virus as a potential bioweapon. With the ongoing advances in genetics research and technologies, biological weapons does not looks anymore as a promising movie plot (The zombie nation!) or the higher level weapon in a video game. Even so, manufacturing an effective weapon using germs (viruses, bacteria, fungi or other) would require advanced knowledge and ... Read more »

Fossilisation and Vegetation Patterns: Another Study of Decay and its Implications

by Isabelle Winder in Going Ape

Following on from my recent post about the decay of chordate animals, I have encountered a related paper, this time from Quaternary Research and focusing on the preservation of plants in middens (rubbish dumps) constructed by woodrats. This paper, written by Nowak et al. (2000), explores the question of how well these middens represent the vegetation surrounding them, by developing a method which calculates the probability that species that are missing from the midden are actually not present in........

Happiness opposed to despair/ennui; sadness to anger/irritability

by sandygautam in The Mouse Trap






Image via Wikipedia



We normally view happiness and sadness to be opposites on a single continuum, but I propose that it is time to change the textbooks and view happiness as opposed to ennui/despair and sadness as opposed to anger/irritability when it comes to basic opponent affects.
But before we go down that path first a detour.

Neury Thursday (Weekend Edition): Neuronal Origin of Handedness

by Allison in Dormivigilia

In this week's Journal of Neuroscience, European researchers have recognized that though humans are innately endowed with handedness, owing to a greater, hemispheric-specific distribution of cortical matter within the premotor cortex, this unequal cortical distribution can be modified post-birth through deliberate practice, producing either ambidexterity or anti-handedness (if of course, practice is maintained)....

Black men in women’s work do not get to ride the glass escalator

by Christina Pikas in Christina's LIS Rant

This post reviews a fairly recent article that examines the experiences of black men in nursing and asks whether they experience the "glass escalator" effect or if the work is racialized as well as gendered.

As requested by some fellow Sciblings, I recently blogged about an older article* that coined the term glass escalator. In my post I was uncertain about how the findings from the study were viewed by experts familiar with that body of work. In the comments, Kris D, who identifies........ Read more »

Succès hollywoodiens et transformée de Fourier

James E. Cutting, professeur de psychologie à Cornell a mesuré la durée des plans de 150 films tournés entre 1935 et 2005. Première chose étonnante : ces films d'une durée moyenne de 126 minutes contiennent de 231 plans pour "Seven Year Itch" (1950) à 3099 pour "King Kong" (2005) , et en moyenne 1132 plans d'une durée toujours aussi moyenne de 6.68 secondes seulement...

Institute of Physics S&TC evidence submission – what’s actually wrong with it?

by Andy Russell in Our Clouded Hills

There’s clearly some interest in the IoP evidence submission and my original letter to the IoP didn’t really go into my objections in great detail. I thought I should go through the evidence submission in one place instead of explaining my views in response to blog comments.
Overall, I’m not objecting to the statement because [...]... Read more »

Blowing molybdenum sulfide bubbles

by Lars Fischer in EuCheMS 2010 Blog

There has been a veritable hype around fullerenes and carbon nanotubes in recent years, so this modification of carbon has extensively researched. What’s a little less known, is that there are other, very similar structures, made of inorganic building blocks, usually transition metal chalcogenides. There is, however, a difference: In most of the inorganic fullerens [...]... Read more »

Culture and the human genome: a synthesis of genetics and the human sciences

by Wintz in A Replicated Typo

Humans are immersed in culture from birth. It is so fundamental to our experience, and what it means to be human itself, yet we often overlook the consideration that “cultural practices might have transformed the selection pressures acting on humans” (Laland, Odling-Smee & Myles, 2010, pg. 137).

For those of you with some sort of investment in human evolution, it’ll be quite clear that gaps between culture and biology are being broached by a variety of researchers. Anthropol........ Read more »
