      Anthrax Toxicity Depends on Human Genetics

      The white powder that arrived in envelopes addressed to lawmakers and journalists in 2001 proved to be a deadly delivery for several people. The lethal substance—spores commonly known as Anthrax (from the bacterium Bactillus anthracis )—can cause a toxic reaction in a host's blood stream, killing cells and leading to tissue damage, bleeding and death.But just how toxic anthrax is to an individual might depend on their genetic makeup, according to a new study, published online Monday in Proceedings of the National Academy of Sciences ...

      Octopuses Survive Sub-Zero Temps Thanks to Specialized Blue Blood

      Octopuses' oddities run deep—right down to their blue-hued blood. And new research shows how genetic alterations in this odd-colored blood have helped the octopus colonize the world's wide oceans—from the deep, freezing Antarctic to the warm equatorial tropics.The iron-based protein (hemoglobin) that carries oxygen in the blood for us red-blooded vertebrates becomes ineffective when faced with low-oxygen levels...
