Today's edition of quick hits:* Right message, right messenger: "President Obama on Friday implored voters [in Cleveland] to 'reject a dark and pessimistic vision' offered by Donald J. Trump and urged a robust turnout on behalf of Hillary Clinton in a state where the presidential candidates are locked in a razor-thin contest."* This is not all right: "Two Donald Trump supporters flashed their firearms outside a campaign office in Virginia on Thursday night, in what they said was an effort to protest Democratic presidential nominee Hillary Clinton and unite likeminded voters."* This won't end well: "The Nevada state Assembly on Friday approved legislation that will devote $750 million in public tax money to the construction of a new NFL stadium. The subsidy is the largest ever for an American sports stadium."* Overdue: "The Justice Department said Thursday that it would begin collecting nationwide data on deadly police encounters early next year, starting the most ambitious effort the federal government has ever undertaken to track police killings and the use of force after a series of episodes embroiled cities across the country in protests and investigations."* Ginsburg's walkback: "Supreme Court Justice Ruth Bader Ginsburg is apologizing for characterizing as 'dumb and disrespectful' the national anthem protests by San Francisco 49ers quarterback Colin Kaepernick and other athletes. The court released a statement from Ginsburg on Friday in which she said she was barely aware of the anthem protest and that her comments were 'inappropriately dismissive and harsh.'"* Age of the Geek: "I'm a science geek. I'm a nerd, and I don't make any apologies for it," President Obama said yesterday.* And speaking of science: "The universe -- or at least the 'observable universe,' the part we're theoretically capable of detecting from Earth -- is much more crowded than scientists had thought. Previous estimates, based on the Hubble Deep Field images captured in the mid-1990s, suggested that around 100 billion or 200 billion galaxies swirled within our line of detection. But a new analysis suggests a figure 10 times higher than that: There may be 2 trillion galaxies in the observable universe, 90 percent of which are too faint for our best telescopes to detect."Anything to add? Consider this an open thread.
