Florida Declares State of Emergency as Hurricane Irma Continues to Gain Strength

A state of emergency has been declared in all Florida counties as the rapidly intensifying Hurricane Irma—now a Category 5 storm—is expected to cut a swath through the Caribbean and then shift northwards towards the US coast.

What Present-Day Hunter-Gatherers Can Tell Us About the Bacteria in Our Gut

The Hazda is a small group of hunter-gatherers living in the central Rift Valley of Tanzania, one of the few remaining groups of people left in the world who still collect the majority of their diet through foraged foods. Modernity has still managed to touch their lives, of course, but far less than it has for those of us in the post-industrialized West. For this reason, scientists have long been interested in studying their biology, in hopes of gleaning something about humanity’s evolutionary path.

Wild Theory Suggests Heavy Metals Came From Black Holes

If you were to rank the wildest things in the universe, there are a few obvious contenders: gamma rays, fast radio bursts, and quasars, for example. But no list would be complete without black holes and the black hole’s less-dense cousins, the neutron star. These hyper-compressed things can do some mind-boggling warping to the shape of space itself. So, what happens if one were to eat the other?

Parasitic plants dwell in darkness, feeding on mold and mushrooms

You might be under the impression that plants photosynthesize—using energy from the sun to turn carbon dioxide and water into delicious and nutritious sugar—and you’re mostly right. Even carnivorous plants like the Venus flytrap practice this process to some extent (though nutrient-poor environments and inefficiency often lead them to supplement their diets with something a little bloodier). But not all flora are capable of feeding off of the sun. Some long ago abandoned this ability, having evolved other ways of gathering nutrients.

Sperm Counts Have Plummeted Among Western Men, Scientists Confirm

Something weird is going on with human sperm production. For decades, scientists have warned that sperm counts are dropping among Western men, but no one has really been able to prove it. In what is now the largest and most comprehensive study of its kind, scientists have presented compelling evidence in support of this rather alarming assertion, showing that sperm counts have dropped more than 50 percent in just four decades.

Incredible Video Reveals that Rainbows Actually Go All the Way Around

It turns out the recognizable half-circle arch of a rainbow is a complete lie. When you’re standing on the ground looking up at a rainbow in the sky, the curvature of the Earth usually blocks its bottom half. But when viewed from a higher vantage point, like from a plane, or the top of a crane, rainbows are magically revealed to be a complete circle.
