Trump's Next Coup Has Already Begun
Technically, the next attempt to overthrow a national election may not qualify as a coup. It will rely on subversion more than violence, although each will have its place. If the plot succeeds, the ballots cast by American voters will not decide the presidency in 2024. Thousands of votes will be thrown away, or millions, to produce the required effect. The winner will be declared the loser. The l

Scientists Are Building a "Black Box" to Record the End of Civilization
Apocalypse Cam If — or when — human civilization collapses, what will remain? Maybe parts of some cities. Or the Statue of Liberty, a la " Planet of the Apes ." Overall, though, there might not be a lot of evidence left behind about what humanity accomplished — or what resulted in its downfall. One team of researchers wants to change that. Their solution? A massive, indestructible box that'll rec

Iron integral to the development of life on Earth and the possibility of life on other planets
Iron is an essential nutrient that almost all life requires to grow and thrive. Iron's importance goes all the way back to the formation of the planet Earth, where the amount of iron in the Earth's rocky mantle was 'set' by the conditions under which the planet formed and went on to have major ramifications for how life developed. Now, scientists at the University of Oxford have uncovered the like
