3:00 PM | dN(eutralist) > dS(electionist)? Part 2
Last week’s post dealt with the debate over differences in the efficacy of purifying selection across human genomes. This week, we’ll look at the differences in de novo mutation rates across populations. The human de novo mutation rate has gone … Continue reading →

1:40 AM | Gone fishing for epigenetic fish…
Apologies to anyone who has been wondering what has happened to this blog. Well it’s a long story involving writing and designing two e-books and two physical paperbacks of the same. All the blog material on this site has inspired my research and discovery leading to massive blogs that are being published as I write […]

8:10 PM | Rules for the black birdwatcher
SUMMARY: Black bird watchers are rare birds themselves, and there are special rules that the black birder must observe to remain safe when out in the field chasing rare birds. . “Any bird that’s black is my bird.” Are you a bird watcher, especially one who chases rare birds? If so, you most likely are white, fifty-five or older, and male. Female birders and young birders are unusual (in my experience), but the rarest birds of all are non-white birders.... Read more

4:40 PM | Sweet Briar College closing
TPP read this news item with a bit of nostalgic sadness. Sweet Briar was called one of the southern seven sisters; a women's college for young ladies of good breeding. This does not mean TPP has any direct connection to Sweet Briar, and everything about it was learned mostly in a two day period 40 years ago on what was one of a young botanist's first job interviews. After giving a presentation at a national meeting, this young PhD (26 at the time) was approached by the Chair of Biology at […]

There are few things I enjoy more than when someone takes the time to clearly communicate a complex idea. The whole “you don’t know it until you teach it” phenomenon gives me the utmost respect for those who put effort into … Continue reading →

3:00 PM | Ferns are weird…
“The love between ferns knows few bounds” Apparently, two fern species, separated by 60 million years were able to produce a viable offspring. That’s roughly the equivalent of a human being able to successfully mate with lemurs. Read about it (or listen to the story from NPRs Morning Addition) over at NPR.

1:00 PM | Looking Sideways In The Mirror
Biology Concepts – platyhelminthes, asymmetry, bilateral symmetry, evolution, cephalization, natural selection, fish, lepidophagyWhat is the largest living structure on Earth? No, it’s not the 2200 acre Armillaria ostoyae fungus in Oregon that we talked about previously. That is the largest single organism, but there is something bigger. The Great Barrier Reef houses more species of coral than any other place on earth, more than 600 species call the reef home. You see how […]

8:00 AM | Overcoming implicit bias
I have been working through The Behavioral Foundations of Public Policy, edited by Eldar Shafir, and have mixed views so far. As I go through, I will note some interesting points. The opening substantive chapter by Curtis Hardin and Mahzarin Banaji is on bias – and particularly implicit bias. Implicit biases are unconscious negative (or positive) […]

4:49 AM | Another day, another microbiome journal ... alas not as "open access" as claimed
Just got this emailDear Doctor Jonathan Eisen,I would like to invite you to consider submitting a paper to our recently launched Open Access journal Microbiome Science and Medicine (http://www.degruyter.com/view/j/micsm).As can be seen from the titles of articles published in our first volume, MICSM reflects the full breadth of research in the diverse areas of microbiome-related science, from molecules to ecosystems:Newton ILG, Sheehan KB, Lee FJ, Horton MA, Hicks RD "Invertebrate systems for […]

10:29 PM | A Third Year in the Freezers
Happy Third Blogoversary, WIJF blog! I am thick in some paper-writing, so I can’t write my usual detailed summary of the past year. Or so I thought, then I started writing and finished it, so here it is! I didn’t feel I needed to post this, but I like retrospectives and writing this helps me […]

6:42 PM | Very cool cargo trike
Just look at this very cool, very innovative, electric-assisted cargo tricycle.  Wow!  Who wouldn't want one of these?  Perfect for visiting your local farmer's market or running to the neighborhood bakery or wine shoppe. This one is a Raiooo, made in Portugal, and it  involves so many nifty things you would do best to go and read about over at Treehugger where there are more images too. Innovative bicycles just keep showing up making you think they are a favorite […]

6:25 PM | Ice is nice (?) and will suffice
TPP's major achievement for today is to have gotten to the safety of his office without breaking a hip. As a nice change of pace in the winter weather, over night the area was treated to a very thin, very slick glazing of ice produced by freezing rain.  This first near fall occurred while fetching the morning newspaper from the front steps. It was treacherous out there, and TPP witnessed several sliding cars, a sliding city bus, cars unable to go up even gentle slopes, and people […]

12:16 PM | Behavioral individuality reveals genetic control of phenotypic variability
Studies of animal personality (or, “behavioral syndromes”, if you choose your words carefully) are so hot right now. One of the assumptions of such studies is that natural selection has somehow favored this behavioral variability/plasticity (and not just differences in … Continue reading →

7:23 PM | Climate expert bought and paid for by fossil fuel companies - not really news
Fossil fuel industry caught taking a page out of the tobacco playbook (link).  That's the headline from the March 3, 2015 online version of the Guardian. This refers to people finding out that W. Soon failed to tell people where his money comes from, but this is not really news.  This was known, but obviously not widely known, at least 18 years ago.  Here’s bit of history from an article (The Wall Street Journal Blurs the Lines Between Science, Opinion, & Politics […]

3:44 PM | Sometimes selection gives you more bang for your buck
Most species experience many environmental stressors simultaneously which means the direction and magnitude of evolutionary responses will depend on trade-offs between traits whose relationship may prevent them from being simultaneously optimized. Multiple sources of stress may act in opposing ways, for … Continue reading →

1:00 PM | NIH distorts report showing risk of stroke after chiropractic
Why would an NIH center try to mislead the public about a newly published study that it funded? Last month NIH’s alternative medicine center, NCCIH, highlighted one of its studies with this headline: “Low risk of stroke after chiropractic spinal manipulation in older patients with neck pain, study finds.” This sounds reassuring, unless you read the study. It turns out that the risk of stroke was up to two or three times higher in patients who saw a chiropractor […]

9:35 AM | The Birds and the Trees | @GrrlScientist
Today’s “Museum Monday” video shows how museums are central to the process of shedding new light upon the relationships within the avian Tree of Life.“If you’ve seen one little brown bird, you’ve seen them all.”As any beginning bird watcher can tell you, many bird species tend to look alike, even those that are not at all related. On the other hand, close relatives may look very different. But appearances and behaviour can be deceiving: for example, […]

8:44 PM | Sunday Chess Problem
One of the underappreciated aspects of chess composition is that some problems have a sense of humor. Sure, the real classics show deep and surprising ideas and do so with impressive constructional finesse. But other problems just bring a smile to your face. This week I have two such problems for you. Neither is difficult…

9:19 PM | Friday Fabulous Flowers - Olfactory edition
TPP walked into the glasshouse and immediately knew that the taro (Coleocasia esculenta) was in bloom. Generally most people don't notice the distinctive fragrance nor the actual "flower" which hides among the large leaves. This is an aroid, Jack-in-the-pulpit being the best known member of the family here abouts. So, what you really have here is a spike of flowers, an inflorescence known at the spadix, surrounded by a modified leaf, a bract, known as a spathe. In the case of taro only half the […]
