Modern proteomes contain putative imprints of ancient shifts in trace metal geochemistry
Because of the rise in atmospheric oxygen 2.3 billion years ago (Gya) and the subsequent changes in oceanic redox state over the last 2.3–1 Gya, trace metal bioavailability in marine environments has changed dramatically. Although theorized to have influenced the biological usage of metals leaving discernable genomic signals, a thorough and quantitative test of this hypothesis has been lacking. Using structural bioinformatics and whole-genome sequences, the Fe-, Zn-, Mn-, and Co-binding metall

Inner Mongolia yields "living fossil"
Tiny teeth discovered in Inner Mongolia belong to the prehistoric ancestor of the modern-day birch mouse. The 17-million-year-old teeth belong to a new species of birch mouse, Sicista primus, identified by paleontologist Yuri Kimura, Southern Methodist University in Dallas. Kimura, a member of the scientific team that discovered the fossils, says the find distinguishes the genus Sicista as a "living fossil, placing it among some of the most unique rodents on earth — those whose ancestry spans

Brain: The Inside Story's "Your Emotional Brain"
Your brain gets information from two different sources: Your senses tell you what's going on in the outside world, while your emotions exist inside your body to tell you what these events and circumstances mean to you. Just as hunger motivates you to find food, emotions motivate you to take care of other needs—like safety and companionship—that ultimately promote survival and reproduction. The exhibition, Brain: The Inside Story, which is on view at the American Museum of Natural History fr
