(Credit: Andrew Preble/Unsplash) When the solar eclipse swept across the continental U.S. in August, it carved a subtle, but noticeable path through our atmosphere. For the first time, researchers confirmed that that moon’s shadow generates a pair of bow waves in Earth’s ionosphere, similar to the wake a boat leaves as it travels through the water. The waves are caused by the sudden drop and rebound in incoming energy from the sun, and they ripple through the atmosphere ahead ...read more

Are You a Directionally Biased Kisser?

(Credit: Shutterstock) Your brain is an organ of two halves – the left side and the right side. And there are many brain functions, such as language skills or which hand you write with, which are organized mostly in one side of the brain or the other. Simple behavioral tests have now allowed us to see how this organization is revealed through biases in how we see and interact with the world – and each other – often without us being aware of it. Examining how people perceive a ...read more

The first wave of invaders likely numbered 48 or more, according to new research. (Credit: kzww/Shutterstock) In 1992, Hurricane Andrew ripped it’s way across the southern US. Southern Florida, where Andrew made landfall, was one of the hardest hit areas. It’s estimated that over 100,000 homes were damaged, and 63,000 were destroyed—among them an expensive beachfront house with a very large and memorable aquarium. That aquarium contained six lionfish, and when it br ...read more

The future that never happened: A bustling Mon base as envisioned by a NASA study in 1986. (Credit: NASA/Dennis M. Davidson) NASA’s human spaceflight program has been in a state of uncertainty pretty much from the moment the Apollo 17 crew left the surface of the Moon 45 years ago this month. The Space Shuttle never became the hoped-for workhorse that would makes space access cheap and routine; the International Space Station never became a glorious gateway to deep-space exploration. Now ...read more

If you’re like me, your family’s Christmas tree is dripping with poorly-made ornaments you and your siblings slapped together in kindergarten. Seriously, one is just a picture of me with some spray-painted puzzle pieces around it. If you’re lucky enough to live in a small part of Australia, though, you could probably gussy your tree up this year with a festive snail. (Disclaimer: This is a bad idea and will get you in a lot of trouble.) Attenborougharion rubicundus i ...read more

Dead Squid Moms Are a Gift to the Ocean Floor

Posted on Categories Discover MagazineLeave a comment on Dead Squid Moms Are a Gift to the Ocean Floor

Animals living on the ocean floor, where it’s too dark for anything to grow, have to wait for food to fall on them. Mostly this means they eat “marine snow,” a steady drift of tiny life forms and detritus from the ocean’s surface. But robotic expeditions off the coast of Mexico have revealed what might be another major dining option on the ocean floor: dead squid moms. The Monterey Bay Aquarium Research Institute (MBARI) sent one of its remotely ...read more
