I was intrigued by the fact that some apoptotic cells can recover if not engulfed by another cell. DNA reassembly after the caspases tear it apart should result in many gene mutations. While most of the mutations would result in cell death, perhaps a few cells would have mutations that promote a cancerous or precancerous […]

Why has so much focus been placed on protecting us against the threat of a smallpox outbreak when a terrorist could choose to release a different infectious disease? Wouldn’t it be wiser to discuss ways to respond to and contain any unknown disease? More public awareness of this possibility would prevent the false sense of […]

I was intrigued by your article for a couple of reasons. Isn’t this what Steven J. Gould said, that evolution is punctuated by environmental stresses that can bring about adapt-or-die changes rapidly? Also, what are the implications for the geneticists who base their mitochondrial DNA dating techniques on what they consider a fairly constant rate […]

Team locates anthrax-receptor protein
Scientists have identified the protein that enables the anthrax toxin to attach to cells and trigger disease, while another team has mapped the molecular structure of the toxin component that does most of the damage to cells.
