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."



Climate Change Causing More Change in Rainfall, Fiercer Typhoons, Scientists Say

Climate change is driving changes in rainfall patterns across the world, scientists said in a paper published on Friday, which could also be intensifying typhoons and other tropical storms.

Taiwan, the Philippines and then China were lashed by the year's most powerful typhoon this week, with schools, businesses and financial markets shut as wind speeds surged up to 227 kph (141 mph). On China's eastern coast, hundreds of thousands of people were evacuated ahead of landfall on Thursday.

Stronger tropical storms are part of a wider phenomenon of weather extremes driven by higher temperatures, scientists say.

Researchers led by Zhang Wenxia at the China Academy of Sciences studied historical meteorological data and found about 75% of the world's land area had seen a rise in "precipitation variability" or wider swings between wet and dry weather.

Warming temperatures have enhanced the ability of the atmosphere to hold moisture, which is causing wider fluctuations in rainfall, the researchers said in a paper published by the Science journal.

"(Variability) has increased in most places, including Australia, which means rainier rain periods and drier dry periods," said Steven Sherwood, a scientist at the Climate Change Research Center at the University of New South Wales, who was not involved in the study.

"This is going to increase as global warming continues, enhancing the chances of droughts and/or floods."

FEWER, BUT MORE INTENSE, STORMS

Scientists believe that climate change is also reshaping the behavior of tropical storms, including typhoons, making them less frequent but more powerful.

"I believe higher water vapor in the atmosphere is the ultimate cause of all of these tendencies toward more extreme hydrologic phenomena," Sherwood told Reuters.

Typhoon Gaemi, which first made landfall in Taiwan on Wednesday, was the strongest to hit the island in eight years.

While it is difficult to attribute individual weather events to climate change, models predict that global warming makes typhoons stronger, said Sachie Kanada, a researcher at Japan's Nagoya University.

"In general, warmer sea surface temperature is a favorable condition for tropical cyclone development," she said.

In its "blue paper" on climate change published this month, China said the number of typhoons in the Northwest Pacific and South China Sea had declined significantly since the 1990s, but they were getting stronger.

Taiwan also said in its climate change report published in May that climate change was likely to reduce the overall number of typhoons in the region while making each one more intense.

The decrease in the number of typhoons is due to the uneven pattern of ocean warming, with temperatures rising faster in the western Pacific than the east, said Feng Xiangbo, a tropical cyclone research scientist at the University of Reading.

Water vapor capacity in the lower atmosphere is expected to rise by 7% for each 1 degree Celsius increase in temperatures, with tropical cyclone rainfall in the United States surging by as much as 40% for each single degree rise, he said.
