There's been a sharp increase in recent decades in the number of young Americans who report they've been arrested at least once, researchers report in Pediatrics, the journal of the American Academy of Pediatrics.

While in the mid-1960s about 22 percent of Americans reported having been arrested by the time they turned 23, researchers estimate that the "prevalence rate" for arrests by that age now lies "between 30.2 percent and 41.4 percent."

A bill before Congress that would allow some types of "robocalls" to be made to cellphones if consumers have given companies their numbers doesn't have many sponsors and wouldn't seem to be the kind of legislation that would stand much of a chance of passing when an election year looms.

But it's getting an increasing amount of attention this week thanks to something that's very rare these days — bipartisan opposition.

The news that scientists at the European Organization for Nuclear Research in Switzerland will talk Tuesday at 8 a.m. ET about "the status of their searches for the Standard Model Higgs boson" has reignited speculation that they might be about to say they've found the so-called God particle.

When he walked down a line of seated Occupy protesters Friday at the University of California Davis and shot pepper spray directly at them, campus police Lt. John Pike likely never thought that video of the incident would go viral on the Web, that there would be outrage not only at the school but around the nation, or that "casually pepper spraying cop" would quickly become one of the year's top memes.

It's not the final word, but scientists at the Italian Institute for Nuclear Physics report today that "new tests conducted at the Gran Sasso National Laboratory of INFN by the OPERA Collaboration, with a specially set up neutrino beam from CERN, confirm so far the previous results on the measurement of the neutrino velocity."

This probably isn't going to satisfy many of those who think of The X-Files as a documentary series, but the Obama administration has now put the White House on record as saying the government doesn't have any evidence of life "out there."

And the Obama team doesn't believe anything's being hidden from us.

There's been a huge increase in the wealth gap between older Americans and those just entering adulthood, according to a new analysis of Census Bureau data done by the Pew Research Center.

According to Pew's study:

In 2009, "households headed by adults ages 65 and older ... had 47 times as much net wealth as the typical household headed by someone" under 35 years of age. Pew says that "back in 1984, this had been a less lopsided 10-to-1 ratio."

And if someone really ticks you off, sleep on it before posting about what happened. You might decide in the morning that it's best left unsaid.

That last bit of advice comes to mind with the story of a Seattle bartender who exposed a "nasty non-tipper" on her Facebook page and mistakenly identified the wrong guy — causing headaches not only for him but for her as well.

Her murder conviction overturned by an Italian appeals court, American Amanda Knox has left Italy and is making her way home to Seattle, The Associated Press reports.

Now, the BCC writes:

Like many of you, we hope, The Two-Way is planning to take some time off over this holiday weekend.

We may put up a post or two, and will certainly jump back in if there's major news. But the general plan is to resume blogging Tuesday morning.

The reason Americans are have a long weekend, of course, is that Monday is Memorial Day. And that's much more than just the unofficial start of summer.

From this year's presidential proclamation:

The "sleeping air traffic controllers" revelations have cost the head of the Federal Aviation Administration's air traffic control unit his job.

"This morning I met with the head of our Air Traffic Organization, the part of the Federal Aviation Administration charged with operating our air traffic control system," FAA Administrator Randy Babbitt says in a statement the agency just posted online. "Hank Krakowski has submitted his resignation and I have accepted it."

Vivian Schiller, NPR's CEO and president since January 2009, left that job today in the wake of the second high-profile controversy to hit the organization in the past six months.
