12:22 PM | [#2015PostPubRev] QM/MM analysis shows correlation between promiscuity and flexibility
To kick off my 2015 resolution, here’s a paper that uses molecular modelling to correlate the observed promiscuity profile of o-Succinylbenzoate Synthase with the involvement of alternative amino acids within the same active site. Enzyme Promiscuity in Enolase Superfamily. A Theoretical Study of o-Succinylbenzoate Synthase Using … Continue reading →

9:00 AM | Royal BC Museum insect curator position in danger, but you can make a difference
  The following is a guest post by Professor Felix Sperling  I’m always amazed when I see a well-established natural history museum that doesn’t have entomology curators. What are their administrators thinking? Insects form half of the known species diversity of our planet, a fundamental fact that too many people are unaware of. The ecological […]

7:30 AM | The Handicap Principle. Why we behave extravagantly
In the ethologic science, there are many original theories which surprisingly reveal some seemingly strange traits and behaviors. One of these theories, an extremely interesting one, called The Handicap Principle, has been suggested by the Israeli ethologist Amotz Zahavi. According to him, certain phenotypic animal traits or behaviors seem to be, on the first look, […] The post The Handicap Principle. Why we behave extravagantly appeared first on Social Ethology.

11:20 PM | Of Post-Publication PeerReview and 2015
January is a good time to set goals for the year to come. Judging from the success tags as #365papers and #52papers are having on Twitter, I’m not the only one that would like to read ‘properly’ (as supposed to quickly scroll through) a few more papers in … Continue reading →

9:53 PM | It’s plosing first…
Okay, everybody knows how plants can cope with adverse conditions, especially when it comes to dormant organs just waiting to resprout when spring or whatever environmental trigger lights on, and then “whoot whoot”, I’m here. I’m alive and well. This is a sign of resprouting, or let’s pretend. It’s been far too long this blog’s […]

9:14 PM | Energy Tree
You'll be completely blown away by a pretty cool design for some urban green energy, a wind turbine tree, by New Wind. Let's face it, those great big old wind turbines dotting our local landscape are not really very attractive, and generally they are impractical for home and urban use. What you want around your house or along campus or park walkways or in parking lots where you want some attractive trees. So this wind turbine takes the form of a tree, sort of. It might have […]

8:59 PM | Cultural Beings Evolving in the Mesh
This one wrestled me hard. In it I use new terminology and concepts–coordinators, phantasms, cultural beings–as though I know what they mean and am comfortable with them. But that’s not quite the case. It’s only recently that I’ve invented them. It’s one them to use terms in a document where you define them. It’s another […]

7:32 PM | Journal Club: Halfsider: a bizarre half-male half-female bird
SUMMARY: A “halfsider” -- half male and half female bird -- has been mentioned in the news over the holidays. More properly known as bilateral gynandromorphs or tetragametic chimæras, these unusual birds are actually two genetically distinct individuals -- twins -- fused into one being. But what is it like to be such an individual? A recently published paper shares observations of the behaviour and social life of one such individual living in the wild. . "Halfsider" Northern […]

4:03 PM | Dispersal capacity predicts both population genetic structure and species richness in reef fishes
Riginos et al. 2014 Dispersal capacity predicts both population genetic structure and species richness in reef fishes American Naturalist 184:52-64 This was a strange paper for me to read in some ways, because it harks back to some things that I probably should know something about: fish dispersal (honestly!), diversification, and phylogenetic analyses. The basic idea is that fish […]

8:00 AM | Self evident but unexplored – how genetic effects vary over time
A new paper in PNAS reports on how the effect of a variant of a gene called FTO varies over time. Previous research has shown that people with two copies of a particular FTO variant are on average three kilograms heavier than those with none. But this was not always the case. I’ll let Carl Zimmer provide the background: In 1948, […]

5:18 PM | Outstanding trees! Outstanding photography!
Here's a teaser photoessay of some amazing trees, mostly massive old things, truly great trees, "behemoths of biomass and beauty" (the quoted phrase is not TPP's, but he doesn't remember where he saw it). The photographer is Beth Moon and the coffee table book must be amazing.  TPP is tempted even though he swore off coffee table books a few years back. TPP has attempted to photograph a number of pretty amazing trees over the years and it isn't easy especially in the tropics where you […]

Mario Cuomo, governor of New York from 1983-1994, died on New Year’s day. He is a throwback to a time when Democrats weren’t cowards, and were actually capable of articulating a compelling and humane vision of how society should be. Consider this speech, delivered at the University of Notre Dame in 1984. Cuomo was a…

5:46 PM | It's a cat's life
Our cats really have it made. Being home for several days during the holidays you get to see the extraordinary activity level of the typical domestic cat first hand. Yes, if ever one of those cat-cams were afixed to our kitty-girls, the resulting video would only be slightly more exciting than one obtained from a 3-toed sloth. First, be it noted that both cats sleep on our bed, mostly, confining the smaller of us to much less than half the bed, and on occasion actually claiming the entire […]
