4:46 AM | Wooster’s Fossil of the Week: A Middle Jurassic trace fossil from southwestern Utah
Time for a trace fossil! This is one of my favorite ichnogenera (the trace fossil equivalent of a biological genus). It is Gyrochorte Heer, 1865, from the Middle Jurassic (Bathonian) Carmel Formation of southwestern Utah (near Gunlock; locality C/W-142). It was collected on an Independent Study field trip a long, long time ago with Steve […]

11:39 PM | Space as a Matter of Attention
One of the interesting features of the book Attention and Meaning is the way different authors have personal stories about how they found their way to interest in attention. Chapter 4 is by Kai-Uwe Carstensen, whose web page either boasts...

I’m rethinking my feeding enrichment protocols. My pouched rats, Cricetomys gambianus and C. ansorgei, are food generalists but in the lab we feed them commercially available rodent or rabbit... -- Read more on ScientificAmerican.com

9:35 PM | Any help with apple experiment?
TPP is ready to begin a new apple experiment; the last one was a failure. With limited space, TPP has been looking at the columnar dwarf apple trees, basically a central shoot with lots of flowering spur branches. These are probably not ideal, but worth a try. The applke varieties that originally came in such columnar forms have not sounded particularly good; the descriptions make them sound like soft-fleshed apples of the McIntosh sort. A decent apple until you grow up. A local […]

2:00 PM | dN(eutralist) < dS(electionist) Part 5
The neutral theory predicts that species with small census (and effective) population sizes are subject to greater drift (or allele frequency fluctuations), and vice versa. In other words, species with larger population sizes are expected to maintain more neutral diversity … Continue reading →

7:09 AM | A Few More Words About Morality
You really must check in on the big morality discussion over at Uncommon Descent. Barry Arrington has done another post on the subject. It’s just more snarling and buffoonery, but I do suggest browsing the comments. RDFish, the “idiot” who caused Arrington’s latest fit of apoplexy, has shown extraordinary patience and lucidity in responding point…

2:41 AM | Don’t Abandon the Passive Voice in Scientific Writing for the Sake of Storytelling
If you’ve written a scientific paper recently, I’m willing to bet that, during the writing/editing process, someone told you to avoid writing in the passive voice (unless you’d already heard this advice before, and avoided it from the start!). This … Continue reading →

6:36 PM | What's in a name? They're blue and bell-shaped.
A pox on common names is certainly deserved in that they are never precise and often terribly confusing. Still people prefer a fuzzy, whuzzy, common name no matter the consequences.  While walking through our gardens, a friend asked TPP a question as a case in point, "Are those bluebells?"  Yes (In reference to image below.).  "Well, they looked a lot different in England."  How very true; how very observant. There you have it in a nutshell. There are no conventions on […]

6:11 PM | Has Dennett Undercut His Own Position on Words as Memes?
Early in 2013 Dan Dennett had an interview posted at John Brockman’s Edge site, The Normal Well-Tempered Mind. He opened by announcing that he’d made a mistake early in his career, that he opted a conception of the brain-as-computer that was too simple. He’s now trying to revamp his sense of what the computational brain […]

3:23 PM | Coloring book for up-tight flower people
Today is the last day of tax season, a date closely watched at the Phactor household; now it's time to help Mrs. Phactor unwind from the stress and work load of tax season. Perhaps there are more of you out there, not necessarily just tax preparers, but other people with stressful lives, people who need some help to relax, to cope. Well, here's just the thing a great mandala coloring book. A lot of the images are floral because such designs are based upon floral forms which themselves are based […]

2:00 PM | Don’t Trust Your Data
Or more specifically, don’t always trust your own data analysis skills. As a PhD student soon to be on the Postdoc market I am eagerly learning all I can about bioinformatics and coding. Additionally, I really like it. So reading this review of the new book by  Vince Buffalo Bioinformatics Data Skills is both awesome and informative. […]

12:00 PM | Boy Plants Are From Mars …..
Biology concepts – sexual dimorphism, plants, monoecious, dioecious, pistil, stamen, floral scent, ecology, ecological selectionCharles Darwin missed the boat on linking his sexual and natural selection in animals to plants as well. This is odd because he was quite the botanist and spent many years studying grasses and such with his son. The parallels between selection in plants and animals might have strengthened his initial argument, but there would still be dissent about the descent of […]

4:11 PM | Electric cargo tricycle
A regular reader just called TPP's attention to this news article on the BBC about a really nifty electric cargo tricycle.  Totally cool, but TPP is out in front on this one having blogged about that same machine over a month ago!  Do try to keep up with me readers. ;-)  But nonetheless TPP appreciates it when readers send along interesting items or call interesting topics to his attention.  Usually it's TPP who is way behind and out of the loop.

3:59 PM | How to "improve" university professors and destroy higher education in the process
The GnOPe in particular wants to destroy the one remarkably good thing the USA ever constructed: a public education system. The cynical view is that a party that governs by ideology rather than knowledge doesn’t really want a public capable of “critical thinking”.  And in the case of higher education, the GnOPe so dislikes higher education especially that they are willing to toss the economic baby out with the academic bathwater. Of course a lot of people might get upset […]

In Controlling Life (1987), Philip Pauly explores how scientists have sought to manipulate life for the sake of human benefit through a biographical account of the enigmatic biologist-engineer Jacques Loeb. Pauly’s motivation is to point out that the drive for biotechnology in the 1960s was not borne from a vacuum. The lack of historical context, […]
