9:33 AM | A week of links
Links this week: An excellent Econtalk podcast with Jonathan Haidt. Just don’t buy his lines about group selection – my reasons here. Steven Pinker’s amusing article on the Ivy League. Pinker also pointed out this oldie but goodie – Bell Curve Liberals. Greg Clark applies his work on social mobility to immigration. Reihan Salam comments. […]

5:53 AM | Wooster’s Fossils of the Week: The mysterious Paleozoic encrusters Ascodictyon and Allonema
  The above pair of fossils are small sclerobionts commonly found on hard substrates in shallow marine sediments through much of the Paleozoic, especially the Silurian and Devonian. Paul Taylor and I have been studying them for a few years now and our first paper on them was published this summer (Wilson and Taylor, 2014). […]

6:25 PM | Ice Cream 101
Can any university claim to be a distinguished, quality institution of higher learning if they do not have decent ice cream in their student center/union?  Clearly an absurd question to which the answer is equally clear; no. A few universities of the ag/tech sort have dairy science departments where students in ice cream (DS 101) plus advanced studies where less common flavors as well as frozen chunks are explored, sell the products of this academic endeavor with excellent […]

12:00 PM | Diversity in STEM: it matters
Diversity in the sciences is a recurrent topic on this blog (and – well – basically everywhere). Scientific American has an excellent overview on what “diversity” is and why it matters to the STEM fields. So whether you think about these issues a lot or a little, I highly recommend reading “Diversity in STEM: What […]

9:17 PM | Soggy September weather
Usually September is a fairly dry, fairly nice weather month. August had above average rainfall, so things entering September were not too dry. TPP made the observation 3 days ago that some rain would be nice or a few things would need some watering.  Hoo boy!  With a total rainfall approaching 4" in the past 48 hours, everything is well watered now OK. Usually this time of year the lily pond needs some topping up, but now a couple of inches will have to be drained off. […]

2:39 PM | Bacteria Can Really Get Around
Biology concepts – motility, microbiology, bacteria, evolution, gliding, twitching, flagella, pilusThe Giant Devil Ray, or mobula ray (Mobula mobular) can reach 18 ft. (5.4 m) wide. It’s not so much that they fly or glide, they just breach the waves and look like they are trying to flap wings. They were almost fished to extinction in the 1970’s. Their meat was sold as scallops after they cut it out with a round cookie cutter!How many different ways can humans move about? Walk, […]

2:00 PM | Don’t Pet the Fuzzy Caterpillar
Keeping up my posting of interesting organisms, this little guy has been getting a ton of press lately. Adorable, looks like a tribble, and makes you want to cuddle them. But these little guys might be the most venomous insect in the US. So don’t pet the fuzzy caterpillar.

9:12 AM | Nudging citizens to be risk savvy
I should start this review of Gerd Gigerenzer’s least satisfactory but still interesting book, Risk Savvy: How to Make Good Decisions, by saying that I am a huge Gigerenzer fan and that this book is still worth reading. But there was something about this book that grated at times, especially against the backdrop of his other fantastic work. […]

7:16 PM | Biological research funding
This AM on public radio there was a story about the lack of research grant money and what a difficult time biomedical researchers had keeping their research labs going. Now here's the thing, these are biomedical researchers, and they've always had access to more research money than any other part of biology to the point that we like to say the human bio-medical tail wags the biology dog. The hunt for grant money shapes many hiring decisions at research […]

I have since revised it to include a section on Jockers, Macroanalysis: Digital Methods in Literary History (2013). You can […]

4:20 AM | Sunday Chess Problem
I’m feeling a bit bereft now that the Sinquefield Cup is over. Fabiano Caruana won his first seven games, and then drew his last three, to win the tournament by a ridiculous three points (ahead of World Champion Magnus Carlsen). This is certainly one of the great tournament performances in chess history, worthy of mention…

4:00 PM | Story behind the paper: Bonnie Baxter on "A tale of salt and gender" #STEMWomen #Halophiles
After posting A tale of salt and gender: participation of women in halophile research I sent the post to Bonnie Baxter, one of the authors of the article I discussed and I asked if she would be interested in writing a guest post about the "Story Behind the Paper" (for which I have a whole series).  I am so so pleased that she said yes.  I have followed Bonnie's work for many years but this is her first guest post here.  I hope there will be more.  She is a […]

7:20 PM | Understanding 3-way interactions between continuous and categorical variables: small multiples
It can be pretty tricky to interpret the results of statistical analysis sometimes, and particularly so when just gazing at a table of regression coefficients that include multiple interactions. I wrote a post recently on visualising these interactions when variables are continuous; in that instance, I computed the effect of X on Y when the […]
