While it might seem strange scientists would think to develop dipsticks to measure caffeine, how they're making them is even weirder.How about three llamas and two camels.Both types of animals, called camelids by scientists, are among the few whose immune systems produce antibodies that are not destroyed by hot coffee. We did not look into who figured that out, or why.Anyway, the researchers injected proteins linked to caffeine into the five beasts to elicit an immune response. The animals produced antibodies in their blood that were reactive to caffeine. Then in the lab, these antibodies were found to accurately indicate the amount of caffeine in hot coffee and also cold cola.More work needs to be done to move the technique from the lab, via caffeine dipsticks. But that's the goal. "We believe our test would be the first consumer test for caffeine and would be beneficial for anyone wishing to avoid caffeine for health or personal reasons," said lead researcher Jack Ladenson of the Washington University School of Medicine in St. Louis.You would not need camels or llamas to do this at home. The antibodies could be copied in the lab. You could even take the dipsticks into the coffee shop."Unlike other methods for measuring caffeine, which require large and expensive laboratory equipment, this test is potentially adaptable to a format that people could carry with them," Ladenson said.The research is detailed in the June 1 issue of the American Chemical Society's journal Analytical Chemistry.

Dipsticks could check caffeine in your cup
Hold the Phone
In the difficult days after 9/11, White House officials quietly passed the word through Washington's alphabet soup of intelligence agencies: tell us which weapons you need to stop another attack. At the supersecretive NSA, the National Security Agency (also known as No Such Agency), the request came back: give us permission to collect information on people inside the United States. The NSA had been struggling, without much success, to listen in on terrorists who use cheap and easily available encrypted phones, and officials eagerly drew up a wish list, according to a participant in the discussions.

Oops! I Did It Again.
In "My Bad: 25 years of Public Apologies and the Appalling Behavior That Inspired Them," Paul Slansky and Arleen Sorkin retrace the most famous and most ridiculous "I'm sorrys" of the past quarter century. Slansky spoke with Alicia Barney.Who's made the most public apologies? I think Trent Lott was the ultimate apologizer in that he managed to fire off six in the space of eight days. What's your favorite apology? Read More »
Is there a case for conspiracy theories about 9/11 and the Iraq war
About 10 minutes into the ultra-low-budget documentary “Loose Change,” now making its way around the Internet, that late, great genius of addled truth-telling, Hunter S. Thompson, is heard giving his gonzo opinion of the way the American press behaved after 9/11. “Well, let’s see, ‘shamefully’ is the word that comes to mind,” he says.But then Thompson went on.

Lightning strikes plane carrying Sen. Kennedy
A plane carrying U.S. Sen. Edward M. Kennedy from western Massachusetts to his home on the coast was struck by lightning Saturday and had to be diverted to New Haven, Conn., his spokeswoman said.The eight-seat Cessna Citation 550 plane lost all electrical power, including communications, and the pilot had to fly the plane manually, according to spokeswoman Melissa Wagoner. No one was hurt.The Democrat had just delivered the commencement address at the Massachusetts College of Liberal Arts in North Adams and was on his way to his Cape Cod home when the plane was struck around 4 p.m., she said.The jet landed safely at New Haven at 4:11 p.m., said Federal Aviation Administration spokeswoman Arlene Murray.

On politics, women, reform
These days, Talal advocates a constitution that would bind an absolute monarchy by law, "a social contract between the ruler and those who are ruled." The parliament, now an appointed, relatively toothless body known as the Consultative Council, would be at least partially elected, with the right to oversee the budget, monitor the government and question ministers, he said.Women? "Right now, we have more than 2 million female students," he said, shaking his head. Read More »
A Saudi rebel prince has vision for reform
Prince Talal, the son of Saudi Arabia's founder and long the ruling family's bete noire, smiled wryly. "This is what we used to live on," he said, "dates and camel's milk."It was his way of saying: To look ahead, sometimes we need to look back.Talal is 75 now, still tall and formidable, with a glimmer of defiance as he smoked a cigarette, cautiously doled out by an aide.

Recruiting has been a challenge
The Army’s top mental health expert, Col. Elspeth Ritchie, acknowledged that some deployment practices, such as sending service members diagnosed with post-traumatic stress syndrome back into combat, have been driven in part by a troop shortage.“The challenge for us ... is that the Army has a mission to fight. And, as you know, recruiting has been a challenge,” she said. “And so we have to weigh the needs of the Army, the needs of the mission, with the soldiers’ personal needs.”Ritchie insisted the military works hard to prevent suicides, but is a challenge because every soldier has access to a weapon.Commanders, not medical professionals, have final say over whether a troubled soldier is retained in the war zone.
