Einsteinian Relativity At A Personal Scale

This is really cool!:

Scientists have known for decades that time passes faster at higher elevations — a curious aspect of Einstein’s theories of relativity that previously has been measured by comparing clocks on the earth’s surface and a high-flying rocket.

Now, physicists at the National Institute of Standards and Technology (NIST) have measured this effect at a more down-to-earth scale of 33 centimeters, or about 1 foot, demonstrating, for instance, that you age faster when you stand a couple of steps higher on a staircase.

Described in the Sept. 24 issue of Science, the difference is much too small for humans to perceive directly — adding up to approximately 90 billionths of a second over a 79-year lifetime — but may provide practical applications in geophysics and other fields.

Body Mass and Genetics

This is really interesting. It concerns a study in Science Translational Medicine that looked at DNA methylation and body mass. From Science Daily:

In Memoriam: George Williams

I am sure that most of my readers have heard that George Williams has passed away. Williams, for those of you who are unfamiliar with him, was one of the giants of evolutionary biology. His book Adaptation and Natural Selection is one of the must read classics in the field – and certainly one anthropologists of all stripes should be read. His paper Pleiotropy, Natural Selection, and the Evolution of Senescence, for example, contains the the first outline of the grandmother hypothesis – something paleoanthropologists have been arguing about for years. Williams was also concerned with the evolution of sex and a pioneer in the field of evolutionary medicine.

Update 1: Carl Zimmer has a piece that explains how all these different strands come together in Williams work.

Blair Mountain Update

Rickets, Neanderthals, And Lubenow: Part Two

In the previous post in this series I looked at vitamin D metabolism and the effects of vitamin D deficiency on the skeleton. So, lets talk about Lubenow and Neanderthals. Lubenows discussion of Neanderthals and rickets occurs in chapter 14. He begins the chapter by invoking the Genesis flood to explain the ice ages, which only lasted, according to Lubenow, for 700 years (give or take). Continue reading
