8:00 AM | Where ‘Lost’ Fat Really Goes When You Exercise
It's a common misconception that the fat we lose while dropping weight is merely converted to energy or sweated out, but in actuality we mostly breathe out the fat in the form of carbon dioxide. This is because, when broken down, fat recombines into predominantly carbon dioxide and a lesser amount of water. The carbon dioxide escapes through our lungs while the small amount of leftover water is excreted through bodily fluids. The post Where ‘Lost’ Fat Really Goes When You Exercise […]

10:01 AM | Review: Truvia
Stevia, Stevia rebaudiana Over the summer, I just about gave up sugar for a while. I swapped sugar on my porridge for sliced banana, and my afternoon snack for a banana. After trying to get used to drinking filtered tap water all day for a while, I went back to squash (cordial) and tried the sugar-free versions. I’ve never been a big fan of artificial sweeteners, but it was bearable.I allowed myself a spoonful of sugar in my morning tea, and then I was done for the day. The results […]

8:00 AM | Mt. Rainier Could Kill You Without Erupting
Mt. Rainier in Washington State could potentially cause a massive disaster without even erupting. The mountain’s interior is soft and muddy due to hydrothermal forces. Part or all of Rainier may collapse in on itself, creating massive mudslides called lahars which may reach the Puget Sound. Such a collapse could occur without the typical warning signs that would precede a regular volcanic eruption. The post Mt. Rainier Could Kill You Without Erupting appeared first on KnowledgeNuts.

10:00 AM | Survivorship bias and genetics
I was a mathematics major as an undergraduate.  However, not then or since have I been anything that one could call a mathematician.  At least, I hope I learned something about trying to think logically about life even if I never do equations.  But this interest led me to read a new book I was told of, called How Not to be Wrong: the Power of Mathematical Thinking, by Jordan Ellenberg (2014, NY, Penguin Press).This is a popular rather than technical book, but it shows in […]

8:00 AM | The Other Line Really Is Moving Faster Than Yours
We've all been there; we get in line, hoping that we'll be out of the store in no time, and we stand and wait and watch everyone else get waited on first while we're held up. It turns out, it's not your imagination---you really do keep picking the slow lane. Your chances of picking a problem-free lane are slim, and with the randomness of problems that can crop up ahead of you, it's likely that you're going to watch people pass you---all the time. There's a way around that, but our perceptions […]

10:00 AM | (Other) lessons of the Broad Street pump: understanding causation isn't so easy
The iconic John Snow, often referred to as the "father of epidemiology," is commonly credited with discovering the cause of cholera after his careful, empirical examination of the 1854 outbreak of the devastating disease in the Soho neighborhood of London.  But I think it's only with hindsight that we can say this, and I think it's not quite right.Snow was nothing if not a detail man.  A physician, he was very much an empiricist, experimenting and observing to test his ideas about […]

8:00 AM | You Really Can Buy Happiness
If money could buy happiness it seems that our society, which is practically obsessed with consumption, would have the happiest people on Earth. Unfortunately, this isn’t the case. However, it doesn’t mean that money is incapable of buying happiness; we just have to spend it the right way. According to psychologists, we’re far happier when we purchase experiences as opposed to things. And the more we can involve other people in those experiences, the more content we will […]

10:00 AM | Are we still doing 'beanbag' eu(genetics)? Part III. Culpably ignored nuances?
Part I of this series was about the particulate view of genes and their role in evolution and the determination of traits that are here because they were screened by evolution.  Many view all traits as being in this category, and genetic determinism of those traits to be very strong and specific.  But the data are less clear by far than the commitment to that idea.Ernst Mayr criticized the one-gene-at-a-time focus of much of population genetics as 'beanbag' genetics.  Mayr said […]

8:11 AM | The Slave Who Ended The Revolutionary War
In 1781, a British invasion of Virginia prompted a slave named James Armistead to join the colonial army against them. The colonials used Armistead as a spy and sent him into the redcoats' camp to gather secrets. He could have accepted the British offer of emancipation and never again spent another day as a slave. Instead he forwarded vital information back to the Americans. In July, Armistead sent them arguably the most important piece of intelligence of the war: General Charles Cornwallis […]

7:53 PM | A very bioarchaeology Christmas tree!
Grades are in!  Department holiday party is over!  Sure, I'll be working the rest of the week on syllabi for my spring courses, but I decided to spend an hour today putting my own bioarchaeological spin on this book-Xmas-tree meme that's been going around... Merry (very early) Christmas from Powered by Osteons!  (Yes, I know it's actually the first day of Hanukkah today, but if I could figure out how to make a skeleton-book-themed menorah, I would...)

10:00 AM | Are we still doing 'beanbag' eu(genetics)? Part II. History's unlearned lessons?
Yesterday we discussed some of the ways in which particularized views of genomic control and evolution were controversial and that, despite much more knowledge now than when the issues first surfaced nearly a century ago, they are still with us in largely unchanged form--even if with massive amounts of data and lots of chest-thumping about how modern our current view is.One consequence of a genomic causation as highly deterministic and specific is that one comes to believe that once a person is […]

8:00 AM | How A Moldy Burrito Saved A Man From A Wrongful Conviction
On a September night in 1988, there was a gun battle in a central Los Angeles alley. When it was over, one man was dead, another wounded. Despite his claims that he was just a bystander, the wounded man was arrested for murder. For two years, the defendant asserted his innocence. Few believed him, especially after he signed a confession to the murder. And, during the trial, the jurors found it hard to swallow his story. But at the last minute, even as the jurors were about to decide his […]
