The Shocking Truth About Electric Animals

The Shocking Truth About Electric Animals In Wildlife Tags Techablyenginnering Currents June 21 2018 19 Comments Mary Bates An elephantnose fish swims in the Congo River. Photograph by Reinhard Dirscherl, Alamy Some animals are just plain shocking in that they’ve evolved the ability to detect naturally occurring electric fields, while others can produce their own electricity. In a study published today in the journal Science , researchers have worked out how six different groups of electric fish evolved organs capable of generating electricity. All muscle cells have electrical potential, but in these six groups of fish, certain muscle cells evolved over millions of years into cells called electrocytes, which generate much higher voltages than ordinary muscle cells do. This enabled these electric fish, all native to the muddy Amazon River, to employ their active electric sense much like bats use echolocation: to detect obstacles and other animal...

What Are 'Low-yield' Nuclear Weapons?

Techably Engineering Limited What Are 'Low-yield' Nuclear Weapons? BY PATRICK J. KIGER JUL 24, 2018 In the 2018 Nuclear Posture Review, the Trump administration says it wants to increase the existing U.S. low-yield capability, which now consists of about 500 gravity bombs that could be dropped by U.S. aircraft, including about 200 positioned in western Europe. During the 2016 presidential campaign, MSNBC host Joe Scarborough caused a stir by saying that then-candidate Donald Trump repeatedly had asked a foreign policy adviser why the U.S. couldn't use the nuclear weapons in its arsenal. A Trump spokesman later denied that Trump had posed this question. Nevertheless, since Trump became president in 2017, his administration has moved not only to expand the U.S. nuclear arsenal, but to add more "low-yield options" — smaller-scale nuclear weapons that a president could resort ...
