Recently, research has been conducted to see if certain life-history traits could be correlated with DNA mutation rates. By using whole-genome sequence data for 32 species of mammal, the researchers…

This video has become quite popular recently (so if you've already seen it, my apologies). It's about a preacher who claims that (hold on to your seatbelts) becoming christian changes your DNA. …

The ATLAS Collaboration, one of the two high-energy physics experiments at the CERN Large Hadron Collider, has just produced updated results of their ongoing search for new heavy particles decaying…

The blog run by Sascha Vongehr is unscholarly and unprofessional.  It vilifies and attempts to belittle anyone whose ideas about the foundations of quantum mechanics differ from his.  When…
