USPS Hates Your iPadIf you want to snail-mail your iPad, Kindle or other re-chargable device you’d better hop to it. After May 16 the U.S. Postal Service will no longer (knowingly) accept lithium batteries or any device which contains more than 2.0 grams of lithium per battery. Admittedly, lithium batteries can explode in the right conditions, but so can Pop Rocks and soda. Note: these new regulations only affect international shipping not domestic, so if you want to send a soldier an iPad – do it now or you’ll have to use more expensive international shippers.

Butt-Dials Clog N.Y. 911: Of the 10.5 million calls to New York City’s 911 in 2010, 38 percent were butt-dials, reports New York Daily News. A consultant’s study of the city’s 911 system revealed the average 10,700 false calls a day, defined by calls under 19 seconds. In 2003, 29 percent of calls came from cell phones, but that rose to 59 percent by 2010 — hence the jump in butt-dials. That number is expected to keep rising. (12:55 a.m.) via New York Daily News

Manhunt Ends as Suspect Kills Self: The tense hunt for Tennessee suspect Adam Mayes and the two girls he was suspected of kidnapping ended Thursday when Mayes shot and killed himself as authorities closed in on an area in Mississippi where he had been hiding. Thankfully the two girls, ages 12 and 8, were found in good health, although their mother and older sister had been found killed in their Tennessee home April 27. Reports say that Mayes had apparently been obsessed with the idea that the two younger girls were his biological children. Mayes, 35, was found about a mile from his mother’s home in Guntown, Miss.

Romney to Obama: I Can Beat You on Waterskis: Forget debating the economy, health care or gay marriage, Gov. Mitt Romney is ready to take on President Obama in another realm: waterskiing. When asked on Fox News on Thursday if he was “hip” enough to take on the president, the presumptive presidential nominee said, “I don’t think I’ll play the president a round of golf but I’ll be happy to take him through a waterski course.” What’s up with the skiing references? When President Obama was asked about Vice President Biden’s remarks supporting gay marriage days before Obama made his historic endorsement, the president said, “He probably got out a little bit over his skis, but out of generosity and spirit.” Good thing Romney’s waterskiing challenge wasn’t issued to the VP.

Design Change Could Jeopardize WTC Becoming Nation’s Tallest Building: The steel and fiberglass radar dome that in the original design would have enclosed the 408-foot needle on top of the new One World Trade Center building has been deemed too difficult to service and maintain. Without it however the needle is considered just an antennae as opposed to part of the architectural structure that would have raised the building to its symbolic height of 1,776 feet.
