1:49 AM | Tiny Microbe Instigated Huge Permian Extinction
The Permian mass extinction coincided with the timing of a disruption in the Earth’s carbon cycle - but what, or who, played a part in the die-out?

12:57 AM | Iowan proclaimation calls for prayer and humble repentance
Dear Pastor Grandstand (Branstad or something like that), Thank you for your invitation to join in thoughtful prayer and humble repentance, but for what exactly?  Yes, your proclamation was for Iowa, but surely it would still count just across the river, or is the God you mention a small one?  Is repentance necessary because Iowa has been wicked? But no, you say our nation has “fallen from her intended purpose”?  Hmm, TPP didn’t even know our […]

8:41 PM | Highlights from the Keystone Symposium on Stem Cells & Reprogramming
I recently attended the joint Keystone Symposium “Stem Cells & Reprogramming” and “Engineering Cell Fate & Function” at the beautiful Resort at Squaw Creek. In addition to gorgeous weather, there was an amazing lineup of talks demonstrating the power and promise of stem cells and cell/tissue engineering. Here are just a few of the highlights from the meetings:  … Read more

5:14 PM | NBA and WNBA players perform differently with age
Life-history traits are often shaped by a balance between somatic maintenance and reproductive investment. That is, an individual wants their own cells to be active, but also needs to invest in making offspring. This tension between natural and sexual selection can generate age-related physiological trajectories that differ between organisms, environments and populations. In simpler terms, […]

4:59 PM | Ferns have it made in the shade
Here's a great bit of research just reported by my colleague Emily over at the No seeds, no fruits, no flowers: no problem blog.  Everyone knows that ferns grow well in the deep forest shade, but this is no easy trick because that leaf canopy overhead captures most of the sunlight, especially at the blue end of the spectrum. Ferns have a neochrome pigment that allows them to use both red and blue light more efficiently.  This isn't news in and of itself, but the real news is […]

3:27 PM | Return to the Jurassic Paradise of Makhtesh Gadol
MITZPE RAMON, ISRAEL–This week I’m back in Makhtesh Gadol, that great bowl of Jurassic delights. This is the most extensive exposure of marine Jurassic rocks in southern Israel, and it is highly fossiliferous. This is just a brief report. I’ll summarize the latest finds and ideas later. Today I spent most my time sitting on […]

1:32 PM | PostDoc position for a forest modeller with stats knowledge in our lab
We are looking for candidates to fill a 3-yr postdoc position in our lab. The plan is to use Bayesian statistics to connected a process-based forest model to data, and use the fitted models to test the effect of functional diversity on ecosystem responses and community stability. Details here or via NatureJobs.

11:38 AM | Pupfish on the adaptive landscape, or: How I learned to stop worrying and love the cable tie
[ This post is by Christopher Martin; I am just putting it up.  –B. ]Like most evolutionary biologists, when I think of evolution I imagine rugged mountain landscapes, as Carl Zimmer eloquently introduced the concept of the adaptive landscape. Try to imagine a vast landscape connecting the phenotypes of all organisms where spatial location indicates a particular phenotype and the terrain – the height at any particular location – corresponds to the fitness of each […]

4:35 PM | See you in Raleigh!
I’ve just registered (a whole two days ahead of the deadline!) for the 2014 Evolution meetings, which this year are hosted by NESCent at Raleigh, North Carolina. Up to now, my strongest association with Raleigh is from a childhood of watching The Andy Griffith Show, in which Raleigh is the big city from Mayberry’s point […]

3:01 PM | Not Your Daddy’s Falcon
My son and his friend agreed that Falcon was the coolest character in The Winter Soldier.  This was not the red-and-white Falcon with a telepathic link to his pet bird.  This Falcon wore black, and his wings were metal, and he carried machine guns.  Boy, I can’t wait until it’s their turn to be the Daddy whose comics are not good enough. Which is really just me being grumpy, because the new Falcon actually was pretty cool.  ”More of a […]

12:57 PM | Holiday in Mitzpe Ramon
MITZPE RAMON, ISRAEL–Pesach (Passover) begins this evening at sundown, but essentially the holiday has started today as people prepare for this evening’s family seders. The town has gone very quiet as stores have closed and traffic dropped to almost no vehicles moving. I spent the day walking around the periphery of Mitzpe Ramon enjoying the […]

11:30 AM | Trouble in Haven: Resolving conflicts in academia
Sharing a laboratory with others is typically rewarding – peers in close quarters become a sounding post for new ideas and a support network for the highs and lows of research life. But you don’t choose your desk mates and things can go wrong. Regular Naturejobs contributor Shimi Rii recently experienced how small disagreements can escalate quickly. Finding the right way to deal with conflict is not easy but necessary in order to ensure a harmonious work environment.  Read more

8:41 AM | Evidence for the existence of three primary strategies in plants and its relevance to ecological and evolutionary theory
JP Grime. The American Naturalist 111(982): 1169-1194. Evidence for the existence of three primary strategies in plants and its relevance to ecological and evolutionary theory I’m a zoologist who somehow keeps looking at plants, and this paper is probably the best demonstration of how plant and animal ecologists really do seem to think differently (in my mind, […]

2:29 AM | Landscaping challenge
One thing leads to another, and the Phactors done one thing, in this instance, removing several old declining spruces, a big old ugly yew, and a rear-view mirror-removing redbud with no other redeeming features (it grew immediately adjacent to the neighbor's driveway). This leaves a 65 foot, south-facing, bed, our eastern front garden without any trees. After so many years of seeking shade-tolerant plants, to be seeking full-sun plants is quite a different challenge. However, with […]

2:23 PM | Robust Predictive Control
My wife and I were both sick from some nameless fever-inducing alien virus all last weekend.  Fairly horrible.  Not Agent Coulson, “Let me die, please just let me die” horrible, but not pleasant at all.  Thus the flashback. I tried to read a couple of papers about sleep, including A new theoretical approach to the functional meaning of sleep and dreaming in humans based on the maintenance of ‘predictive […]

5:17 AM | Wooster’s Fossil of the Week: An unusual scleractinian coral from the Upper Cretaceous of Israel
Originally this was going to be a mystery fossil for a crowd-sourced identification while I’m here in Israel doing fieldwork, but through the wonders of the internet I finally found a match for the strange fossil above: it is the scleractinian coral Aspidiscus König, 1825 (Family Latomeandridae).  Yoav Avni and I found several specimens in […]

10:03 PM | Bitter greens of spring
TPP appreciates the anonymous tip to this poetic description of spring greens at Salt and Stone Poetry. Although if you considered TPP's comment in the last blog as anything other than saying dandelion greens were the best of a bad lot, then best this author brush up on his writing. You must understand the world of 2, or for most of you, 3 generations back. Over the winter food was canned or winter-stored; cabbage was as close to green and fresh that you got.  My Father […]

MITZPE RAMON, ISRAEL–The tradition we’ve built over the years on our Israel expeditions is to travel to interesting places on Saturdays to take a break from work. Yes, it appears geologists never really stop geologizing, but then that’s not really “work”, is it? Today Yoav, part of his family and I went to the Nabatean-Byzantine […]
