Although Mauna Loa is Earth’s largest active volcano, it has lived in the shadow of Kīlauea since it last erupted in 1984. The geologic record shows that Mauna Loa erupts every seven years on average; however, 37 years have passed since lava flows from the volcano’s Northeast Rift Zone came within 7 km (4 miles) of Hilo.
In the permanent twilight of the mesopelagic, a silent predator hunts.
The enigmatic giant squid is rarely observed in its natural habitat. In the first videos of their kind, marine scientists have caught its hunting behavior in the wild - revealing for the first time how these monsters of the deep stalk and attack their prey.
Although the crushing pressures and darkness of the oceanic depths are hostile to us air-breathing humans, we’ve slowly but surely been learning more about them, thanks to the wonders of robotic technology. Most of our underwater vehicles, however, are best suited to studying slow or immobile organisms.
For giant squid, the bright lights mounted on underwater vehicles can be uncomfortable for their sensitive, low-light eyes, which can grow to the size of dinner plates; the sound and vibration can also scare off more mobile animals. And, of course, bringing giant squid to the surface won’t record their behavior in their natural environment.
Bounty of the Forest: A keystone species of SE Asian forests, the Common red stem fig, 𝙁𝙞𝙘𝙪𝙨 𝙫𝙖𝙧𝙞𝙚𝙜𝙖𝙩𝙖, provides thousands of figs all along its trunks and branches from ground level all the way up to its crown.
Sifting through a shovel load of dirt in a suburban backyard, Michael Raupp and Paula Shrewsbury find their quarry: a cicada nymph.
And then another. And another. And four more.
In maybe a third of a square foot of dirt, the University of Maryland entomologists find at least seven cicadas – a rate just shy of a million per acre. A nearby yard yielded a rate closer to 1.5 million.
And there’s much more afoot. Trillions of the red-eyed black bugs are coming, scientists say.
