Overnight Briefing & General Reality Check

What's the Buzz:

Has NOAH's Ark finally been found? A group of Chinese and Turkish evangelical explorers say they've found wooden remains on Mount Ararat in eastern Turkey, long rumored to be the final resting place for the Ark.
   Those explorers claim that carbon dating proves the relics are about 48-hundred years old, right around the same time the ark was said to be afloat. Scientists are hoping to get clearance for a major dig in the area.(Pacelli)

The Railroads:

Amtrak is test-driving its first "cow-powered" train. The Heartland Flyer is hauled by a biodiesel locomotive, running daily between Oklahoma City and Fort Worth.
   It runs on a mix of 80 percent diesel and 20 percent biofuel. The mix cuts carbon monoxide emissions by 10 percent, sulphates by 20 percent and particulates by 15 percent compared to standard diesel fuels.
   What about the cow part? The biodiesel was refined from beef byproducts (provided by a Texas supplier). That means cow poop.
   Amtrak will test the train for the next 12 months. (Maiman)

Fashion Emergency:

Hey guys --are you looking for a special gift for that "Twilight"-loving lady in your life? The marketing gurus over at the movie company have come up with the perfect idea --a commitment ring based on the film series!
   ContactMusic.com reports fans can now buy a ring just like the engagement band "Edward Cullen" gives to "Bella Swan" in the upcoming sequel, "Eclipse." Author STEPHANIE MEYER helped design the bauble, which will be available in either white or yellow gold for a mere $2,000 and a "fashion version" that runs for a budget-friendly 35-bucks. (Lee)

Broadcast, cable and video news:

CONAN O'BRIEN will be back on TV this weekend --but not as a host --as an interviewee.
   The Hollywood Reporter says he's been signed to appear as a guest on "60 Minutes," as he's interviewed by STEVE KROFT. Terms of his severance from NBC prohibited him from appearing on TV until May 01.
   The interview will not be live --it was reportedly taped last week in Los Angeles.

Look what I found:

Not exactly a $5 donation you'd toss in the bucket --instead, a retired jeweler sorting through costume jewelry donated to a Goodwill near Harrisburg, PA, found a 2.6 carat diamond ring in there. It's value: $17 grand. (Maiman)

Doctors and Nurses:

A Do Not Disturb sign hanging on the hotel room door doesn't seem so out of place. But hanging on a nurse?
   Researchers in Australia believe nurses should consider wearing signs reading, "Do Not Interrupt." According to findings in the Archives of Internal Medicine, each time a nurse is interrupted while she's preparing or handing out medication, the risk of a clinical error goes up by more than 12-percent. The errors themselves become more severe with each added interruption. When a nurse is able to do her job without any distractions, the estimated risk of major error was 2.3-percent. (Page)
