When Americans mark their presidential election ballots later this year, immigration will be top of mind—it's the nation's number one issue, according to pollster Gallup. And one of the toughest talkers on the topic is former president and presumptive GOP nominee Donald Trump. He's built his political career on calls to secure the border and defend America against what he says are immigration's dangers, warning of shrinking wages and stretched benefits pr ... ⌘ [Read more](https://phys.org/news/2024-04-immigrants-immigration-economy.html) 2024-04-05T02:07:27Z **Propelling atomically layered magnets toward green computers**
