Education

The metabolism of most animals follows a circadian rhythm that differs between the day and night. Mexican cavefish living in constant darkness, lost this circadian rhythm some time ago. In a newly published study in PLOS ONE, researchers compared the metabolic rate of both cave- and surface-dwelling Mexican tetra fish (Astyanax mexicanus). They hypothesized that…

Trains of Clocks

My Gen Ed relativity course has mostly been me lecturing about stuff to this point, so on Wednesday I decided to shake things up a bit and convert a chapter of David Mermin’s It’s About Time. The idea was to get students up and moving around a bit, and actually making some measurements of stuff.…

Cassidy Williams: An Emerging Computer Scientist with a Desire to Inspire More Women in STEM

  The ‘Nifty Fifty (times 4)’, a program of Science Spark, presented by InfoComm International, are a group of 200 noted science and engineering professionals who will fan out across the Washington, D.C. area in the 2014-2015 school year to speak about their work and careers at various middle and high schools. Meet Nifty Fifty Speaker…

Cash and Respect

The London School of Economics has a report on a study of academic refereeing (PDF) that looked at the effect of incentives on referee behavior. They found that both a “social incentive” (posting the time a given referee took to turn around the papers they reviewed on a web site) and a cash incentive ($100…

Bad Graphics, STEM Diversity Edition

There was a article in Scientific American about diversity in STEM collecting together the best demographic data available about the science and engineering workforce. It’s a useful collection of references, and comes with some very pretty graphics, particularly this one, showing the demographic breakdown of the US population compared to the science and engineering fields:…

No joke. George (the goldfish) had developed a rather large tumor over the past year and the owners loved the fish so much, they spent $200 to have the life-threatening tumor surgically removed:

Intelligence vs. Priorities

Steven Pinker has a piece at the New Republic arguing that Ivy League schools ought to weight standardized test scores more heavily in admissions. this has prompted a bunch of tongue-clucking about the failures of the Ivy League from the usual suspects, and a rather heated concurrence from Scott Aaronson. That last finally got me…

Fight to save world’s rarest fish

Conservationists are trying hard to save the Devils Hole pupfish (Cyprinodon diabolis) from extinction. With less than 100 animals remaining, a captive breeding program was started at the University of California, Berkeley. As you can imagine from the image below, the geographic range of this fish is smaller than other wild vertebrates. They are only found…

On Academic Scandals

Two very brief notes about high-profile scandals in academia: 1) While it involves one of my faculty colleagues, I have no special insight to offer into the case of Valerie Barr’s firing by the NSF over long-ago political activity. I know and like Valerie as a colleague, and she did some really good stuff as…
