Gray’s paradox was originated by the zoologist James Gray in 1936 (J. Exp. Biol. 13: 192–199, 1936). The paradox questioned how a dolphin is able to swim fast (~10.1 meters per second according to his calculations) with what he saw as a limited ability to generate that much power. Therefore, he concluded that dolphins must have…

An river otter was captured on camera taking on an juvenile alligator…and winning. The battle took place at the Lake Woodruff National Wildlife Refuge in Florida in 2011. More images can be seen on their Facebook page where the images were recently posted, impressive! According to National Geographic, the normal diet of a river otter consists of…

No! Not the list of stumpers again!

There’s a common tactic used by creationists, and I’ve encountered it over and over again. It’s a form of the Gish Gallop: present the wicked evolutionist with a long list of assertions, questions, and non sequiturs, and if they answer with “I don’t know” to any of them, declare victory. It’s easy. We say “I…

Say goodbye to another mammal being sacrificed on the altar of ‘traditional medicine’ — pangolin scales are consumed as medicine, their blood is used in tonics, their embryos are swallowed as aphrodisiacs, and they’re just generally eaten up. They’re also incredibly fragile, and cannot be farmed; they’re all caught in the wild and they usually…

Perovskite solar cells can not only emit light, they can also emit up to 70% of absorbed sunlight as lasers. Critical signaling molecules can be used to convert stem cells to neural progenitor cells, increasing the yield of healthy motor neurons and decreasing the time required to grow them. Mexican blind cavefish are so close…

The evolutionary capacitor

Heat shock protein 90 (HSP90) helps keep proteins in the body folded properly and is thought to compensate for variations that occur in proteins over time. In a study published in Science magazine, Dr. Nicolas Rohner and colleagues showed that stress can affect the ability for HSP90 to do its job thereby unmasking these alternative…
