In the mood for some science on Thanksgiving? 

Me too, science is the one thing that has not been steamrolled by Christmas. Instead, Thanksgiving is arguably the most scientific holiday, because it involves agriculture, chemistry and physics.

If you are worried about chemicals, for example, there is good news on Thanksgiving: You can buy a 100 percent organic, shade-grown, no-GMO meal AND IT WILL BE 100 PERCENT STUFFED WITH CANCER-CAUSING CARCINOGENS.
Today, the NYT reported that Coca-Cola's Chief Scientist is stepping down in the midst of a controversy regarding Coke's support of researchers who emphasize exercise for weight control. Dr.
Well, don't this beat all! An article in The Guardian announcing the 17 newly-honored Presidential Medal of Freedom awardees was entitled, "First EPA chief accuses Republicans of ignoring science for political gain."

100 Years of Einstein’s General Relativity

In 2012, the enthusiasm for poll averaging reached a fever pitch. Very few people were critical of it and instead talked about how science had taken over predictive politics. (1)

I was critical of the accuracy and swam against the tide of those in media gushing about the new frontier opened up by New York Times statistical pundit Nate Silver and others, which posited that we could now predict outcomes with unprecedented accuracy. 'They don't do any polls,' I noted, 'So we are supposed to believe there is some miracle of weighting they do in polls done by someone else.' It's the same flaw we find in epidemiology when a scholar does an unweighted random effects meta-analysis to conclude organic strawberries taste better or whatever.

On Twitter #BlackOnCampus is a collection anecdotes of racial aggression and microaggression.  What does science say? What is the context for these tweets?  I am only one person and can only speak for myself.  However, many others on Twitter are sharing their own stories of what it is like to be #BlackOnCampus.   Those who are not from the United States and those who are not black may be surprised to find out that there are still very real issues with racism.  Things have gotten better even during my life time.

In a bit less than two days an orbiting object known with the peculiar name of WT1190F - but I'd like to rename it as WTF 1190 for obvious reasons - is expected to fall on Earth. The object was discovered by the Catalina Sky Survey in 2013 and little is known about its origin. It has a low density and makes a very eccentric revolution around us every three weeks. 
Below is a picture taken by the University of Hawaii 2.2 meter telescope in October. The object is observed as a bright spot that shows a relative motion with respect to fixed stars.

Scientist who specialize in sex and sexuality tested a sample of men using a device that measures the reaction of a mans privates to various visual stimuli.   Men who are attracted to transgender women were not turned on by porn featuring two gay men, but they were turned on by porn featuring women only, and three kinds of “shemale” porn (“Man on Shemale”, “Shemale on Female”, and “Shemale on Shemale”).   So a man who likes transgender women (people born essentially biologically male who are sociologically more like women) does not have to be “at least” bisexual, or really gay but hiding it, or any such thing.   What studies like this hi-lite is the sparse vocabulary most of us have in the USA.  Word

In the late 1800's, a small, well-formed cylinder composed of platinum and a little iridium (the same alloy used in fine platinum jewelry today) was defined by the international scientific community to have a mass of exactly one kilogram.

This was not a special rock dug up from the Earth, nor a once-in-a-lifetime meteorite fallen from the heavens, but a man-made object that was bestowed this great and important property to be used by generations of scientists and non-scientists. (Happy 125th Birthday, Kilogram!)
