5:28 AM | Wooster’s Fossil of the Week: An asaphid trilobite from the Middle Ordovician of the Leningrad Region, Russia
This weathered trilobite is nothing like the gorgeous specimens of this genus you can buy at various rock shops around the world and on the web, but it has sentimental value to me. I collected it on an epic field trip in Russia in 2009. We hacked our way through the woods to an exposure [...]

3:06 AM | Are introduced North American beavers in Finland losing their dam-building instinct?
I’ve had several people ask me about this article that appeared on a Finnish news website about introduced North American beavers losing their damming instinct. The story goes as follows: Canadian beavers were introduced to Finland in the 1930s after the indigenous European beaver population had been hunted to extinction in the 19th century. There [...]

9:48 PM | Most Muslims ‘accept’ human evolution
I’ve mentioned before that many (most?) Muslims are Creationists, broadly understood. According to Pew’s Religious Landscape Survey 42 percent of American Muslims accept that evolution is the best explanation for the origin of human life on earth. This is roughly in line with the American public, if a touch on the Creationist side. The numbers [...]

9:11 PM | Maternal-fetal health and natural selection
A few years back I was rather fixated on issues of maternal fetal health. In particular I was worried about gestational diabetes in relation to my wife because I come from an ethnic group with an elevated risk for these sorts of problems, and the effect when you are in mixed-race marriages seems to be [...]

8:29 PM | My open letter to SJSU Philosophy
Synopsis: My considered reaction to the suggestion that I may be destroying educationOn Thursday, the Philosophy department of San José State University released an open letter to Michael Sandel, instructor of a Harvard edX MOOC. I reacted to the letter in my post, "Lessons in social justice from MOOCs". I combined a statement of approval for the SJSU department's aims with some pointed disagreement about the logic behind their arguments. Since that post, I have gotten questions from […]

7:43 PM | Free Comic Book Day 2013
The jazz quartet that plays Saturday mornings at Tate Street is tearing it up today.  I popped over Free Comic Book Day for a few minutes to see the costumes, but had too much work to do to wait in line for hours.  Fortunately writing exams and blog posts is work that I can do [...]

6:48 PM | Costs
There are several factors to consider when thinking about purchases. Obviously, the price of the purchase is pretty important.  How much money you have available for the purchase determines whether you will make the purchase at all.  But (especially in our modern internet age) you can spend some time (which is considered a cost) and [...]

5:01 PM | Paleo and "physical culture" movements
NPR has a short piece with an interesting historical story about old-time back-to-nature fitness fanatics: "Paleo Diet Echoes Physical Culture Movement Of Yesteryear" As Hamilton Stapell, a historian at the State University of New York, New Paltz, found when he went digging into the archives of physical culture, there are striking resemblances to the paleo movement today. And, he argues, this shows that people seem to romanticize a healthier past in the midst of great societal upheaval: the […]

4:31 PM | Mob scene turns ugly!
Mobs can be pretty ugly; unruly mobs even more so.  When they all surge in the same direction their energy is like being caught in a tsunami.  Kids, senior citizens, small electric vehicles, all get bowled over in seconds as the relentless mob rolls on.  An NFL offensive line wouldn't stand a chance. Checked the time; it was still a few minutes before 8 AM, which was when our annual arboretum plant sale was scheduled to begin, but this morning cabin-fevered […]

3:53 PM | All the paleonews that's fit to print
The New York Times joins the Neandertal anti-defamation league with an editorial by David Frayer: "Who’re You Calling a Neanderthal?". Neanderthals lived much richer lives than ever presumed. They were not exactly like us, but they bred with us and their genes and behavior are part of our heritage. So, be careful when you call someone a Neanderthal. You’re speaking about part of yourself. Frayer covers many of the last 5 years of discoveries of Neandertal cultural complexity, as well as […]

3:50 PM | Tent caterpillars on a black cherry tree
These are tent caterpillars, the larvae of the moth called Malacosoma americanum. In late April and early May, these caterpillars appear in their little tents in just about every black cherry tree (Prunus serotina), and during certain years, they actually denude the trees of nearly all their leaves.

3:09 PM | "Earth-like"
Recently discovered exoplanet Kepler-62e is the most "Earth-like" planet ever discovered. However, this discovery also forces us to reconsider what we mean by "Earth-like" and how we should think about exoplanets in the future.

I am really missing the States right now. Today marks the most exciting sport event in my book, the 139th Run for the Roses, the most exciting 2 minutes in Sports: The Kentucky Derby! I can’t even watch it on TV. (Pole sana for me.) But I was scanning my Twitter feed and discovered that [...]

3:14 AM | Making generalizations about popular breeds is what morons do
The internet is a place where people go to fight with strangers. And because one can make one’s online identity virtually anonymous, one suddenly realizes that one has license to be as crazy and vindictive as possible. The people who do this as a hobby are known as trolls, but even accounting for those people, [...]

6:25 PM | Hear those crispy rice grains calling for help? Snap! Crackle! Pop!
New scientific findings are often fun and interesting, but how some "journalists" write about such things is annoying to the nth degree.  Xylem consists of a series of cellulosic tubes and during water stress, the transpirational pull upon the water columns, a force generated by water loss from leaves, can generate air embolisms.  In a manner of speaking, xylem gets the bends.  A research group has found that formation of these air bubbles makes sounds.  Now that's […]

5:04 PM | The Chesapeake duck dog
From a piece by George Norbury Appold in The Century Illustrated Monthly Magazine (1885): It is sincerely to be regretted, in view of his exceptionally valuable qualities, that suggested a close relationship to the otter-dog. His ability as a retriever emphasized this supposition. His superior qualities in this direction were so manifestly phenomenal that the few [...]

2:37 PM | Friday fabulous flower - yellow-flowered wild ginger
The warm weather this week pushed a great many spring plants into flower; many of them had been in a swollen bud stage for a couple of weeks held back by the unseasonal cold weather.  Oh, yeah, like the weather today.  This particular spring flower does well in shade and our gardens are so shady, there is a constant quest for new shade-loving plants.  TPP well remembers the first time he observed this plant at the Brooklyn Botanical Garden on our 1st botanical geek tour.  […]

Here’s what we now know. Kiera Wilmot was re-creating the Drano Aluminum foil experiment at school. She was outside, before the morning bell. She recreated one of those Wow! Science experiments, the kind we see on Myth Busters or You’ve Been Warned! Folks love those shows. They love doing that crazy stuff at home (although [...]
