11:31 PM | Phillip V. Tobias, 1925 – 2012

In early 1925, the most important fossil pertaining to human evolution to date was reported from South Africa; the skull of an infant Australopithecine from a locality called Taung demonstrated that our ancestors walked upright, had human-like teeth, and a small, ape-like brain which may or may not have had some human-like features. This fossil’s [...]

Algae Can Cover One-Twelfth of U.S. Annual Fuel Consumption

A new study shows that the U.S. land and water resources could likely support the growth of enough algae to produce up to 25 billion gallons (94.6 million m3) of algae-based renewable biodiesel a year, one-twelfth of the country’s yearly needs. Read more »

TMI Friday: Batteries should NOT be included

There are some days when you have to ask yourself, just what is the deal with men. I don't mean our general demeanour, or the pretensions of superiority over other genders. No, I'm talking about the strange things that men decide to do when left alone for too long.The men who happily dangle their members inside bottles, or in reach of the spinning blades of a vacuum cleaner not thinking of the consequences. With this in mind, we arrive at a case study by Bedi et al, where they […]

“Race, Intelligence, and Genetics For Curious Dummies”

Last week, a cicada-like re-emergence of “Bell Curve” claims of a genetic determinacy between intelligence and race surfaced in a Heritage Foundation special report on immigration. The report drew on Jason Richwine’s Harvard dissertation, “IQ and Immigration Policy.” Amid the furor, the Atlantic’s Ta Nehisi Coates was ready with the history. He wrote in [...]

Beta Decay and Neutrinos over Cocktails

This was going to be so much longer and more detailed, but as you may or may not be aware, seven month olds occasionally decide of their own volition to pull all nighters, (much like grad students). So, I leave you with a few somewhat less than scattered thoughts, and an incredible video on the topic of neutrinos. After yesterday's post on the possibility of the variation of radioactive decay rates with neutrino activity from the sun, I spent my free time today reading about beta decay […]

All lobsters are mortal

This appeared earlier today on the Facebook feed I Fucking Love Science: Argh! I remember seeing a shark documentary as a kid, hosted by Burgess Meredith, if I remember correctly. It made the same basic claim about great white sharks: too big to have predators, nobody had ever seen them die except by accident or by human hands, blah blah blah, therefore “some have suggested” they are immortal. That I can remember the end of the show all these years later shows you what a terrific close […]
