The Trump administration apprehended a total of 1 million migrants at the southwest border of the U.S. in fiscal year 2019, Customs and Border Protection commissioner Mark Morgan told reporters at the White House on Tuesday.

Why it matters: That figure is 88% higher than it was in 2018 and the highest total of any fiscal year since 2007. However, Morgan said those numbers have declined significantly in recent months — with September marking the lowest number of apprehensions for the year. He cited President Trump's June 7 deal with Mexico to stem the flow of migration as a factor in the steep drop.

Twitter will start pinning notices to the top of all U.S. Twitter users’ timelines warning that results in next week’s election may be delayed and that they may encounter misinformation on mail-in voting.

Water on the Moon might be more easily accessible than previously thought, opening up new possible avenues for future human exploration, according to a new study.

Why it matters: NASA is aiming to send people back to the Moon as part of its Artemis program by 2024, with plans to eventually create a sustainable presence on the lunar surface. That sustainability relies on mining the moon for its resources, like water.
