It’s the reporting that was shallow

I recently posted an article questioning some of the conclusions found in the news story, Roots of human family tree are shallow. I just received the abstract and some relevant excerpts from the original article in Nature. Here’s an excerpt explaining some of the assumptions the authors made: Several factors could cause the time to … Continue reading “It’s the reporting that was shallow”

I think the analysis might be shallow

Roots of human family tree are shallow With the help of a statistician, a computer scientist and a supercomputer, Olson has calculated just how interconnected the human family tree is. You would have to go back in time only 2,000 to 5,000 years – and probably on the low side of that range – to … Continue reading “I think the analysis might be shallow”

Time to throw away those aluminium foil helmets

Abstract – Hydrodynamic interactions and diffusion of bovine serum albumin

Recenetly, I posted a list of old files. Here’s the contents of one of those files — the abstract of my master’s thesis. The concentration dependence of the diffusion coefficient of bovine serum albumin (BSA) was determined using data from osmotic pressure measurements and light scattering. The results showed that hydrodynamic interactions had a larger … Continue reading “Abstract – Hydrodynamic interactions and diffusion of bovine serum albumin”
