3:22 PM | Fundamentalists try to set those godless Unitarian-Universalist heathens straight
In a total and absolute reversal of the golden rule, a group of fundamentalist Christians (they come in other flavors) invaded a UU church, well known to be a “Synagogue of Satan", during a service to "witness" to that congregation of godless heathens that they were all bound for Christian hell (hell comes in other flavors too).  This is sort of sadly amusing.  Amusing because TPP can readily imagine the confusion and bewilderment such an intrusion would make upon a UU […]

2:49 PM | That's one strange Thai temple
TPP has been to Thailand several times, and in the process traveled the country from top to bottom and side to side. Somehow TPP missed (?) this temple, Wat Rong Khun, a contemporary religious study in white with some pretty strange features. It's one of those things that you simply have to say is "interesting".  Another "interesting" modern place is the aptly named Ancient City (now called Ancient Siam) outside of Bangkok, which is a huge (couple of hundred acres) outdoor museum […]

12:00 PM | Let's Get Loud
Biology concepts – vocalizations, mechanical sounds, sonar, decibels, stridulation Today it seems that truth is more complex than ever. van Goethe was a German statesman and a very successful writer. He wrote novels, scientific treatises, lyric poems, as well as dramas. Born in 1749, one might say that his quote was true for his day; it was a simpler time. But think how simple our time will seem to those who live a hundred years from now – unless we’ve found our way back to […]

6:38 PM | Great mid-summer flowering - bottle-brush buckeye
A native to south-eastern North America, the bottle-brush buckeye (Aesculus parviflora) is hard to beat for summer flowering.  The Phactors have several growing as part of a semi-shady border, and they are a great plant.  The specimen shown is from our university campus where several shrubs (possibly a clone) hides a dirt bank.  Even in closeup the flowering is quite lovely and attracts a big diversity of insects, including, unfortunately Japanese beetles, who last year really […]

6:21 PM | Bad news
Sometimes you don't know whether to laugh or cry after reading or watching the news. There's the middle eastern living laboratory for demonstrating that tit-for-tat (or is it tit-for-TAT?) is always a loosing strategy.  You'd think they'd learn, but for some reason, probably a historical deafness, leaders of nations don't.  Our country doesn't seem to have learned anything about our "big stick" foreign policy since the Vietnam war because people keep listening to old, dead-wrong, […]

3:48 PM | Feeling the stress of an academic career? Think happy thoughts!
A recent study published in the journal Stress & Health surveyed the mental health and coping strategies of 200 postdocs at UT Austin and found that individuals who thought positively were better able to cope with the stress of an academic position. “Thinking positively can do more than bring a transient smile to your face.

There’s plenty of science and religion stuff out there, but I think talking about anything else right now would be to ignore the elephant in the room. There’s a basic moral principle that I subscribe to that goes like this: When your neighbor is relentlessly firing rockets at you in an attempt to kill as…

7:21 PM | Weeds, weeds, weeds!
The Phactors don't want to talk about weeds; it's been a very bad year.  Black nightshade, poke weed, wild lettuce, lambs quarter, and Oxalis (Not sure about the species, probably O. stricta; too busy pulling it to ID it.) have been plentiful, robust, and aggressive, some growing to impressive sizes. In an effort to prevent them from producing more seeds, weeding has been a primary garden activity this year.  But even after weeding one area, you return to an earlier area, and […]

3:41 PM | Footage of the 8th International Congress in Genetics! (Stockholm, 1948)
While searching for information regarding Åke Gustafsson, a plant breeder who practiced mutagenesis (and cited by Stebbins as providing experimental data for mutation studies), I stumbled upon an amazing video: footage from the 8th International Congress in Genetics held in Stockholm in 1948! Bengt Bengtsson and Anna Tunlid of Lund University digitized and annotated the video (the […]

10:04 PM | How to kill an iZombie
Sometime back TPP commented on iPhone zombies, but a similar affliction can also occur due to ear buds and whatever they are delivering from an iPod, so the result is an iZombie. Like all zombies, you have to know the right way to kill them, but based on recent events that may not be too difficult. You turn an ordinary person, often a student around here, into an iZombie by giving them a smart phone and a set of ear buds either attached to the iphone or an ipod, either or both […]

7:40 PM | Robert Kennedy's Anti-Vaccine Craziness
Robert Kennedy is obsessed with the notion that vaccines cause autism. He’s particularly obsessed with the discredited idea that thimerosal, a preservative used in some vaccines, causes autism. Now Kennedy is about to publish a new book on this topic, and he’s promoting it both in the press and, as described in today’s Washington Post, in the halls of Congress. He’s recently had personal meetings with U.S. Senators Barbara Mikulski and Bernie Sanders to try to convince […]

10:45 PM | Barbarians and their enablers
You give a kid a BB gun, and sooner or later he'll shoot it at some windows. It's a given of human nature. You give rebels, terrorists, or even some other type of militia under limited central control some big boom-booms, and sooner or later they'll shoot at something they shouldn't have.  And of course giving an implement of destruction to anybody who is more likely to shoot than to think makes you partly responsible for the outcome. This means you really have to think […]

In 1842, the infamous showman P.T. Barnum unveiled a truly bizarre creature.
