Scientists Explain Veggies Suffer Jet Lag, Too

Humans aren’t the only ones whose internal clocks get all out of whack when they fly. It looks like vegetables also feel the effects of jet lag, which happens when our light and dark cycles are thrown off. Toward the end of this factoid-filled video from Mashable there’s a longer explanation, plus a silly skit about a jet-lagged eggplant. And here’s a report from NPR that explains how scientists are using this knowledge to coax vegetables into producing more beneficial compounds.

Toying with the idea of conducting an experiment of your own? Make sure you follow the rules of the Transportation Security Administration, or any other international agency, before bringing any food on board a plane or across borders. Carrot circadian clocks aside, here are some tips from Gadling readers that might help you ward off jet lag on your next trip.

Passenger Surprised When TSA Finds Dagger Inside Cane

Each week, the Transportation Security Administration (TSA) details some of the items they uncovered during airport searches on their blog. This week the administration found not only a record 50 firearms (45 which were loaded), but also a curious cane that concealed a 2.5-inch knife (pictured).

According to the blog, even the woman carrying the cane was surprised to find the blade inside when she tried to pass through a security checkpoint at Washington Dulles International Airport.

“It’s important to examine your bags prior to traveling to ensure no prohibited items are inside,” said the TSA. “If a prohibited item is discovered in your bag, you could be cited and quite possibly arrested by local law enforcement.”

At airports this week, officials also found 10 stun guns, two inert grenades and a can of tear gas.

TSA Postpones Allowing Knives On Planes

It looks like travelers will have to wait a little longer before bringing their pocketknives and golf clubs on board planes. According to Forbes, the Transportation Security Administration (TSA) has postponed their earlier decision to allow small knives and sporting good equipment in carry-on luggage, a rule that was supposed to go into effect on April 25.

Many people, including flight attendants and other airline employees, criticized the new rules after they were announced in March. A CNN contributor backed these oppositions in a highly circulated op-ed. It seems the TSA is listening, and will now look to the Aviation Security Advisory Committee (ASAC) for further input on what should and shouldn’t be on the Prohibited Items List.

Although these items aren’t allowed in the cabin, travelers can still pack them in checked luggage. So for now, it looks like our sports outings and camping trips will continue to include a baggage fee.

Expect Delays As Sequestration Cuts Hit Airports

Automatic spending cuts began hitting the Federal Aviation Administration on Sunday, meaning travelers should be prepared for longer security lines and lengthier waits at airports as things get sorted out.

According to NYC Aviation, delays of up to an hour were cited in and around New York on Sunday night, with both John F. Kennedy International Airport and LaGuardia Airport reporting delays due to “staffing.” Already this morning, several flights are seeing lengthy delays, including the shuttle services up and down the East Coast.

The Chicago Tribune is reporting the FAA has warned, “travelers should expect delays averaging as much as 50 minutes per flight this week because of fewer air traffic controllers in towers.” But don’t worry too much: no sector of air space will go without controller guidance. Just be sure to check flight statuses before you set off to the airport, and allow plenty of time to get through security – lines are expected to be slow-moving as Transportation Security Administration personnel have been furloughed, too.

CNN Contributor Doesn’t Welcome Blades On Board Planes

The Transportation Security Administration (TSA) recently announced less restrictive rules for carrying knives on planes, a move CNN opinion columnist Bob Greene calls “insane” and “dimwitted.”

In early March, the TSA declared it would soon allow knives with blades shorter than 2.36 inches in length, and no wider than a half-inch, to be carried onto flights. The green-lighted knives cannot have a molded grip or a blade that is fixed or locked into place, meaning pocket knives are pretty much the only exception. Although, as Greene explains, there has been push back from members of Congress and aircraft crew members, the TSA has shown no sign of rescinding the decision, which should go into effect on April 25.In a press luncheon late last month, Homeland Security Secretary Janet Napolitano explained the reasoning behind the new policy: “We’re trying to prevent a bomb from getting on a plane. And if you are talking about a small knife, there are already things on a plane that somebody can convert into a small, sharp object.”

But Greene clearly disagrees, writing there is still a whole lot of risk involved in allowing knives on planes, and pointing out it was blades–not bombs–that allowed terrorists to take over planes on 9/11. However, he fails to note the many ways air travel has changed since the attacks, both at the airport and on the plane, including the creation of the TSA, increased screening processes, fortified aircraft doors and trained air marshals, not to mention a motivated passenger base willing to fight back. He also doesn’t mention that box cutters, the weapon used in the 9/11 attacks, will not be permitted to be carried on planes when the new rules go into effect later this month.

Greene’s other argument is that the move won’t speed up airport screening. He envisions TSA officers holding up the line to pull out rulers and ensure blades are falling under the 2.36 inch mark. But since small pocket knives are pretty much the only tools that will be allowed on planes, it seems pretty easy to quickly identify what is up to snuff and what’s not.

As someone who always carries a tiny Swiss Army Knife on my keychain, there’s been more than one occasion I’ve forgotten to leave it at home. I’ve had to forfeit two to airport security, and there’s been once or twice when I passed through the checkpoint with the tiny tool. It’s nice to see the TSA is implementing some concrete rules that conform to international standards, and I’ll be happy to soon travel with my knife (and screwdriver, and can opener and toothpick) in tow.
