Accident On The Trail? Science, Nature To The Rescue

by Chris Owen on

On the trail, adventure travelers know the importance of basic first-aid skills when thousands of feet up on a climb, camped miles from nowhere or hiking off the beaten path where a call to 911 brings help. When an emergency happens, knowing what to do can mean the difference between life and death.

New research done at the University of Michigan, Harvard University and the City University of New York indicate that brain stimulation releases an opiate-like pain killer. Using electricity on certain regions in the brain of a patient with severe pain, scientists were able to release one of the body’s most powerful painkillers.

Hikers, campers, climbers and others commonly off the grid when traveling, might find this ability useful when an accident happens. Waiting for first-responders to arrive with help can be a very long time when in severe pain.

A natural substance produced by the brain that alters pain perception, called mu-opioid receptors (MOR’s), is the hero here.

“This is arguably the main resource in the brain to reduce pain,” said Alexandre DaSilva, assistant professor of biologic and materials sciences at the U-M School of Dentistry and director of the school’s Headache & Orofacial Pain Effort Lab in Laboratory Equipment.”We’re stimulating the release of our [body’s] own resources to provide analgesia,” adds DaSilva. “Instead of giving more pharmaceutical opiates, we are directly targeting and activating the same areas in the brain on which they work. [Therefore], we can increase the power of this pain-killing effect and even decrease the use of opiates in general, and consequently avoid their side effects, including addiction.”

Looking for other natural painkillers may not require waiting for science to arrive at our favorite gear store though. In this video, Kate Armstrong, The Urban Forager, shares how to find a natural pain killer from nature.

Travel By Car Driving Obesity Epidemic, Say Researchers

by Chris Owen on

Holiday travel by car might be less expensive than flying, a train trip or a Christmas cruise to festive destinations, but new research urges caution while driving – not for safety’s sake, but because of a direct relationship suggested between body mass index (BMI), calories consumed and automobile travel.

A new study by University of Illinois researchers suggests that both daily automobile travel and calories consumed are related to body weight. Reducing either one, even a little bit, correlates with a reduction in body mass index (BMI), the study found.

“We’re saying that making small changes in travel or diet choices may lead to comparable obesity reduction, which implies that travel-based interventions may be as effective as dietary interventions,” says graduate student Banafsheh Behzad in a Business Standard report.

Using publicly available data on national average BMI, caloric intake and driving habits, the study found that driving just one mile a day less can make a difference.

“One mile is really not much,” Behzad says. “If they would just consider even taking the bus, walking the distance to the bus stop could have an impact like eating 100 calories less per day. The main thing is paying attention to caloric intake and moving more, together, can help reduce BMI.”

Great idea. But if I walked to the bus stop I would have to swing by the gas station on the way to buy donuts, “for the trip,” throwing the national BMI way off track.

On the other hand, childhood obesity is declining, probably because little kids don’t drive. This video tells the story:

Traveling With Food Allergies Easier With Smartphone Add-On

by Chris Owen on

Traveling with food allergies requires an extra measure of caution for those affected. In the past, that caution may have kept them from sampling local fare, a big part of any travel experience. Now, a new smartphone add-on will allow allergy-suffering travelers to test their meal at restaurants, food trucks, sidewalk cafes or any other dining venue around the world.

I have a friend in the UK who has a fish/seafood allergy so severe that if she so much as smells fish, a reaction occurs. If a tiny speck of fish accidentally makes its way in or on to something she eats? Off to the hospital she goes. She is far from alone.

Unique food allergies, sensitivities or restrictions with reactions that can be severe, and even life-threatening, affect millions of people, both children and adults. While traveling, those affected can’t rely on others to help; the down side to them being wrong is just too much of a gamble.Airlines provide special meals for these travelers if notified in advance. Food labels can indicate potential problem ingredients. Asking servers what is in food can help too. But until now, nothing allergic travelers could do would guarantee food safety.

To give allergic travelers a high level of confidence that what they are about to eat is safe for them, researchers from the University of California, Los Angeles (UCLA) developed the iTube.

Using the cellphone’s built-in camera, the iTube, along with a smartphone app, runs a test with the same high level of sensitivity of a laboratory. Unlike other mobile devices that detect allergens, the iTube is easy to use and much less bulky, according to the UCLA researchers at the Henry Samueli School of Engineering and Applied Science.

“We envision that this cellphone–based allergen testing platform could be very valuable, especially for parents, as well as for schools, restaurants and other public settings,” says Aydogan Ozcan, leader of the research team and a UCLA associate professor of electrical engineering and bioengineering in the UCLA Newsroom.

Can’t wait for the iTube to hit the shelves of your favorite gear store? A Food Allergy Translation Card iPhone App may help while you wait, as we see in this video:

Marijuana Tourism Not A Big Surprise In Colorado, Washington

by Chris Owen on

Marijuana Tourism got two thumbs up in the elections earlier this month as the states of Washington and Colorado made selling, buying and using cannabis legal. Never mind the federal law prohibits any of that; the voters have spoken and opened the door for what could be promoted as Weed Weekends, Bong Backpacking and a variety of marijuana-related tourism options.

State government leaders were quick to put the brakes on a massive migration to either state, saying a lot of details still have to be worked out. Colorado’s governor opposed the legalization vote but indicated after its passage that he didn’t see marijuana tourism taking over the state and its iconic tourist attractions.

”I don’t think that’s going to happen,” Democratic Gov. John Hickenlooper said in a Boston.com report. ”They’re going to flock here to buy marijuana as if they’re going to take it back? On an airplane? That seems unlikely to me.”

Still, while public use of marijuana is not part of the deal, possession and personal use very much is. That applies not to just state residents, but to visitors also.

Anyone 21 or older can legally posses up to an ounce of recreational marijuana in Colorado and grow up to six plants. That’s the law. On a legal focus, they can’t use it in public, the rules for medical marijuana (already a $1.7 billion industry), are unchanged and the “possession no problem” element clock starts ticking now. Previous marijuana crimes stick.Disregarding the federal law for a moment, these states could indeed legislate the implementation of a state-licensed marijuana industry. Much like states control and tax alcoholic beverages, mostly free from federal intervention, millions in revenue could be generated to support otherwise underfunded programs like education.

It’s not like Colorado and Washington are new to the world of marijuana either and the recent vote to legalize it could be viewed as a natural progression.

Colorado and Washington are part of 18 states and Washington, D.C., that have legalized medical marijuana for people with medical conditions like cancer, nausea, multiple sclerosis, migraine headaches and chronic pain.

In Colorado, many ski slopes already have old mining cabins that have been turned into ”smoke shacks,” places to smoke marijuana out of the wind and cold. Breckenridge, Colorado, dropped criminal penalties for marijuana use two years ago.

In Washington state, for over 20 years, travelers have come from all over the world for Seattle’s HempFest (pictured), an annual gathering that advocates the decriminalization of marijuana. This year, 250,000 attended as police looked on.

Will the entire states of Colorado and Washington become much like one huge Amsterdam, where without trying all that hard visitors can freely enjoy marijuana? Probably not.

We’re not apt to see a “World’s Largest Pot Plant” attraction on highway road signs in Colorado any time soon and Seattle probably won’t have Space Needle-shaped bongs in the near future.

In Colorado, it will be a year or more until the state has a system in place to allow retail sales, but that probably won’t stop celebrities who support the idea as we see in this video.

TSA Removes X-Ray Body Scanners From Major Airports, But Some Will Remain

by Jessica Festa on

For all those who are against having to go through X-ray body scanners at airport security, you’ll be happy to know some are now being removed. During the past few weeks, the Transportation Security Administration (TSA) has been quietly switching them out for safer radiation machines.

While the main goal of the change is to speed up the lines at security checkpoints in major airports, the transition will also lead to less passengers being exposed to radiation.

So far these X-ray machines, called backscatters, have been replaced at Boston Logan International Airport, Los Angeles International Airport, Chicago O’Hare, Orlando and John F. Kennedy in New York.

One concern people have with the backscatters is the fact that the radiation has been linked to cancer at higher levels. Moreover, the machines produce images of passengers’ naked bodies. The new millimeter-wave scanners help these problems by instead emitting low-energy radio waves similar to those in cellphones, as well as producing generic cartoon images instead of the person’s actual body.Before you get too excited, know the backscatters are not being phased out altogether. They are still being used at certain airports, including some major ones. Additionally, in late September the TSA awarded three companies potential contracts for the next generation of body scanners. One of the systems, made by American Science & Engineering, uses backscatter X-ray technology.

“They’re not all being replaced,” TSA spokesman David Castelveter told ProPublica. “It’s being done strategically. We are replacing some of the older equipment and taking them to smaller airports. That will be done over a period of time.”

The upside to this is research has found the radiation emitted from the body scanners is trivial and nothing to worry it. That being said, many scientists are also arguing that if there is a safer alternative that allows passengers more privacy, the TSA should use it.

“Why would we want to put ourselves in this uncertain situation where potentially we’re going to have some cancer cases?” David Brenner, director of Columbia University’s Center for Radiological Research, told ProPublica last year. “It makes me think, really, why don’t we use millimeter waves when we don’t have so much uncertainty?”

Nothing is simple, however. Research has shown the millimeter-wave scanners have a much higher false-alarm rate, 23% to 54% compared to 5% with backscatters. The TSA hopes using both machines in different airports will lead to competition, creating better technologies at a lower cost.
