Why Don’t Woodpeckers Get Headaches?

Have you ever wondered why woodpeckers don’t get headaches? It is quite remarkable when you think about it. This bird, on a regular basis, subjects its brain to 1000 g of deceleration every time it pecks (g represents the acceleration due to gravity acting on all bodies on the surface of the Earth), and it […]

Fossils of Ancient Shark Relative Found in South America

There are only two currently living species of bramble shark in existence today – Echinorhinus cookei and Echinorhinus brucus. The picture above shows Echinorhinus brucus. They live off the coast of Argentina, Chile, and in the Indian Ocean typically at depths of 1,300–3,000 feet so they are rarely encountered by swimmers. They are purplish brown or black […]

An Overlooked Opportunity to Breath Without Oxygen

Pure Manganese III oxide powder, an electron acceptor. Unlike humans, who depend on oxygen to breathe, bacteria have the ability to breathe many other molecules besides oxygen. While most of our Earth is soaked in oxygen, there are areas that have little to none. In sediments at the bottom of lakes, oceans and marshes, oxygen […]

Choosing a Weapon Against Antibiotic Resistance Just Got Easier

They say what doesn’t kill you makes you stronger, and this applies just as well to infectious diseases. Antibiotics have revolutionized medicine and dramatically increased human life expectancy, but we are in the midst of a post-antibiotic era. Many drugs that used to be effective against infections are becoming less so, and researchers and clinicians […]

Tumbleweeds Interrupt the Discovery of Black Holes

“How moving!” is what the Earth would say when it comes into contact with gravitational waves. Albert Einstein’s general theory of relativity predicted these gravitational waves. These waves are disturbances in space caused by very massive objects and events. LIGO, (Laser Interferometer Gravitational-Wave Observatory) located in Livingston, Louisiana, has a press release from last summer […]
