For several decades, scientists have toyed with the idea of primordial black holes. In the smorgasbord of particles and forces and energy of the beginning, slight overdensities might have led to the formation of small black holes. But not too small. Because under a certain limit, these objects would have wiped out the universe already. […]

Bother a leafhopper nymph and you’ll be faced with quite the display. These insects have evolved a truly wacky way of expelling wax from their derrieres, ranging from flailing “fiber-optic” strands to cotton-like fluff.

Humans confirmed the existence of other galaxies surprisingly late. Only 100 years ago, in fact, when Edwin Hubble found a type of star known as Cepheid variables within Andromeda, and used them to measure the galaxy’s distance. Advertisement As luck (or, in fact, proximity and gravity) would have it, astronomers soon figured out that Andromeda […]

The giant black hole at the center of our galaxy has an unexpected spin, which is likely to be the result of a merger with another large black hole.

In this evolutionary process, a harmless species evolves to resemble a more dangerous species, warding away potential predators.  For many predator-prey pairs, evolution is a multi-generational battle. The prey evolves a hard shell; the predator evolves shell-shredding fangs. […]
