German Police are currently considering an unfamiliar proposal: the use of bees in drug detection, just like dogs. The idea has made headlines in the police magazine. Officer Sonja Kessler, 22, who keeps hives as a hobby, revealed her idea in her graduation project entitled "drug detection bees… a revolution in the police mission."

In her paper, Kessler said dogs deployed for drug detection work for a short term, focus on specific people, and require a time consuming and expensive training. So, why don't we use bees instead of dogs?

According to the German News Agency, the European Police Congress honored Kessler for her research this year.

Drug detection bees: unfamiliar research or crazy idea?

According to experts, bees have a great sense of smell and can be trained to recognize and report odors.

For this purpose, the little insects should be kept in a container, a tube for instance, according to Peter Rosenkranz, head of the Baden-Württemberg State Institute for Bee Science at the University of Hohenheim. During the training, the bees smell certain material, and at the same time, lick a sugar solution. By repeating the process several times, the bees master the targeted smell.

The moment those little insects sniff the smell, they point their stingers through which they absorb the nectar, because they expect a sweet treat.

Rosenkranz stresses that bees have an accurate smelling sense that can be as effective as dogs.

Rosenkranz said that during an educational course, he trained bees on recognizing different cigarettes brands.

"Only 20 bees can be used, and put in a briefcase-like container, to detect drugs in train stations or an airport checkpoint. The idea had been practically tested," he noted.

For her part, Kessler believes that a bee can do more than that.

"The reward approach can be used to build and rehabilitate full beehives," she said in the article published in the police magazine.

The "bee detectors" that fly freely can monitor wide spaces expanding over up to 50 km square. The little insects can also be covered with a fluorescent powder so they can be recognized by drones. Bees can be deployed to uncover drug farms and to detect explosives found in the world wars ammunition remnants.

Yet, the young bee lover admits that the bee's free movement depends on weather conditions and the right season. A legal frame that regulates the work of those trained bees is also needed to determine the legal consequence if a bee stings a suspect while sniffing him, for example, or whether it can be used as admissible evidence in court.

In spite of these limits, Kessler sees that bees can be an efficient assistant, and hopes police can benefit from these little insects in their work.

The German Police Syndicate didn't reject the idea.

"We shouldn't laugh about the proposal. We are actually considering it," said a police member who works as an editor in the police magazine and spokesperson to the syndicate.

The spokesperson said the syndicate received many positive responses about this idea, noting that bees can be deployed to serve the federal police, along with dogs trained on drug control.

Commenting on the police syndicate's statements, officials in the Federal Police said: "Generally, the federal police do not comment on the syndicate's statements, since the police are not directly related to such issues. But, officials are advised to consult customs to see if bees could be used to help check the contents of the bags."



Should You Stretch before Exercise? After? Never? Here’s What to Know

Should You Stretch before Exercise? After? Never? Here’s What to Know

For many people of a certain age, high school gym class began with reaching for their toes. Then, over the years, we were told it was better to stretch after exercise.

It turns out, both those things can be true, but the differing advice has created some confusion.

Stretching can help make you more flexible, improve range of motion in your joints — and feel good. David Behm, who researches human kinetics at Memorial University of Newfoundland in St. John’s, Canada, offers this advice on when to stretch and how to do it safely:

Warm up first

It’s almost always good to stretch, but it’s better if you warm up first, said Behm, author of "The Science and Physiology of Flexibility and Stretching." He recommends a light aerobic activity such as jogging, walking or cycling for five or 10 minutes.

Follow that with some static stretching, the traditional way of reaching and holding a position (think back to that gym class). You can then do activity-specific dynamic stretching, in which you warm up the muscles with repetitive movements like leg lifts.

Behm says one minute is "the magic number" for how long to do static stretching per muscle group without fatigue.

Expand your definition of 'stretching'

Should you always stretch before exercising? If it's traditional stretching, not necessarily.

The better question, Behm says, is, "Should people increase their range of motion? Should people have better flexibility? And that is yes, because it helps prevent injuries. It helps with health. But you don’t have to stretch to achieve that."

Resistance training, for instance, can be an effective form of stretching, he said. Doing a chest press increases range of motion in your deltoids and pecs, whether with barbells, dumbbells or machines, so there is no need to stretch beforehand. Just make sure to start with a small amount of weight to warm up and then add more to train.

"You probably don’t have to do extra stretching unless you’re a gymnast, a figure skater, or even a golfer who needs a great range of motion through that swing," Behm said.

Nor do you need to stretch first if you’re going for a leisurely run. Simply start with a slow jog to warm up and then increase the pace.

Don't do it if it hurts

After exercise, "light stretching is OK, as long as you don't reach a point where you're feeling pain," Behm said. Since your muscles will be warm by that point, overdoing it makes you more likely to injure yourself.

Foam rollers can help with muscle recovery and have been shown to increase range of motion as well as stretching.

Do some static stretching before sports

If you’re playing a sport, Behm said, static stretching beforehand helps reduce muscle and tendon injury.

"If you’re going to do an explosive movement, change of direction, agility, sprint, any of these explosive activities that involve your muscles and tendons," he said, "you’re going to be stronger if you do static stretching."

People can especially get in trouble when they go back to a sport they used to play, whether it's tennis, surfing or any sort of team activity.

Also, stretch both sides equally. Lacking flexibility on one side also can lead to injury.

Sounds simple. Why all the confusion? Different studies over the years have either encouraged or discouraged stretching before exercise. Behm says that partly because some studies didn't reflect real-life conditions, or were designed with elite athletes in mind, not regular people.

"If you’re Usain Bolt, it makes a difference," said Behm. Not so much for the rest of us.
