Average Number of Recessive Lethal Mutations Carried by Humans

April 26th, 2015

Recently Gao et. al. published “An Estimate of the Average Number of Recessive Lethal Mutations Carried by Humans”. They studied a Hutterite group in South Dakota, highly inbred (63 founders 13 generations ago). From serious genetic diseases common in this population, they determine the number of deleterious variants present in the founders. They find that 0.29 recessive lethal alleles per haploid genome. Since some lethals manifest before birth, they double the estimate to 0.58.

This gives an expected 1.8% increased chance of a genetic disease from two first cousins.

Gao, Z., Waggoner, D., Stephens, M., Ober, C. & Przeworski, M. Genetics 199, 1243–1254 (2015).

Measles vaccine nonsense

February 1st, 2015

I was sent a link to a blog post, “This Mama Isn’t Scared of the Shmeasle Measles” by Megan Heimer.

I’ll run through the post in a minute, it contains a whole lot of nonsense. First, some links to reliable info:
CDC measles info

Measles week posts by an immunologist

Now, on to the post…

Modding a Sunbeam heating pad

November 21st, 2014

I bought a Sunbeam heating pad. It has low/med/high settings, and turns off after two hours.
heating pad

The back of the controller says ‘Sunbeam SLA103’.

I wanted to eliminate the shutoff, I’m using it to heat my fermentation bucket.
