The existence of ancient proteins is no surprise. Evidence of remnants of durable, skeleton-associated proteins such as collagen are not uncommon in the fossil record long before Tyrannosaurus rex. For example, remains of bivalve ligaments are known from the mid-Ordovician, over 400 million years ago. Other durable but pliable organic materials, such as protist resting […]

I was interested to read in this article that running portable generators caused carbon monoxide poisoning, presumably by improper fuel burning. A good solution to this problem is to use a generator that is designed for much lower emissions. I use my Toyota Prius as an emergency generator that can power my house! It can […]
