Vampire bats, boas, pythons, and pit vipers―like rattlesnakes, copperheads, and cottonmouths―all have specialized infrared-sensing organs that allow them to determine if something might be prey. Of these creatures, the pit vipers’ “pit,” which is located between its eyes and nostrils, is by far the most sensitive.

Humans don’t need to learn the ability to move to a rhythm, according to a new study. They are born with it. Two researchers from Finland and the United Kingdom wanted to find out how soon in life people begin to dance to rhythms. They were surprised to find that babies as young as five months old match body motion to music.

Following a magnitude 8.8 earthquake on February 27, 2010, Chile experienced a 7.2 magnitude aftershock on March 11, the same day that President Sebastian Pinera was sworn into office.¹ Considering the size of the initial earthquake, it is no surprise that the aftershock was significantly powerful, and more strong aftershocks remain likely.

On February 27, Chile experienced an 8.8 magnitude earthquake, the fifth-largest recorded quake since seismographs were implemented. Charles Darwin experienced a similar quake in the same area on February 20, 1835. The conclusions he drew then provide an interesting contrast to what is now known about earth’s geologic activity.

A fossilized lemur-like creature, nicknamed "Ida," was broadly heralded in 2009 as one of man’s earliest ancestors. At the time, and despite the hype, various paleontologists expressed doubts regarding the placement of this fossil in man’s evolutionary tree.
