Japanese researchers demonstrated how a tiny remote-controlled drone could help bees pollinate flowers in areas where bees populations have been reduced due to pesticides, climate change, and other factors. Eijiro Myako and his colleagues at the Japan’s National Institute of Advanced Industrial Science and Technology hope that eventually robotic bees could handle their share of the work autonomously. From New Scientist:
The manually controlled drone is 4 centimetres wide and weighs 15 grams. The bottom is covered in horsehair coated in a special sticky gel. When the drone flies onto a flower, pollen grains stick lightly to the gel, then rub off on the next flower visited.
In experiments, the drone was able to cross-pollinate Japanese lilies (Lilium japonicum). Moreover, the soft, flexible animal hairs did not damage the stamens or pistils when the drone landed on the flowers...
“We hope this will help to counter the problem of bee declines,” says Miyako. “But importantly, bees and drones should be used together.”

For years, entomologist Brandon Hopkins has argued for the establishment of a germplasm repository for cryopreservation of honey bee semen. Unfortunately, bee semen us very hard to collect and even harder to preserve, but Hopkins found better ways to extract and store their genetic material. Read the rest

Reuters reports that the U.S. Fish and Wildlife Service proposes listing the rusty patched bumble bee among America's endangered species.
Though just one of many species of bumble bee, Bombus affinis's sharp decline is a worry to conservationists. About a quarter of bumble bee species face "a risk of extinction."

The agency attributes the decline to a number of factors, including disease, pesticides, climate change and habitat loss.
Bumble bees, as distinguished from domesticated honey bees, are essential pollinators of wildflowers and about a third of U.S. crops, from blueberries to tomatoes, said Sarina Jepsen of the Xerces Society for Invertebrate Conservation, which petitioned the government for protection of the insect.
Bumble bees’ annual economic value to farms is estimated at $3.5 billion, according to experts.
New research shows that bees can recognize flowers by the plants' tiny electric field that differs between species. The electric field bends the tiny hairs on a bee's body, firing neurons located at the base of the hair. From the journal Science:
Such fields—which form from the imbalance of charge between the ground and the atmosphere—are unique to each species, based on the plant’s distance from the ground and shape. Flowers use them as an additional way to advertise themselves to pollinators...
Electric fields can only be sensed from a distance of 10 cm or so, so they’re not very useful for large animals like ourselves. But for small insects, this distance represents several body lengths, a relatively long distance.

Granted, the nail was loose, but it is remarkable to see a bee work it out of the hole. Two questions: what was the nail doing in the hole in the first place, and why was the bee so intent on getting it out?

"Brain scans of insects appear to indicate that they have the capacity to be conscious and show egocentrico, apparently indicating that they have such a thing as subjective experience." That's the finding of study written by Andrew B Barron and Colin Klein, and published in the Proceedings of National Academy of Sciences.
From the Independent:
They found that in both, consciousness appeared to be associated with the “midbrain”. That part of the brain is the ancient core of the brain, which supports awareness for us and apparently for insects, too.
Though insects have tiny brains, they appear to serve the same function that the midbrain does for humans. They are able to tie together memory, perception and other key parts of consciousness, and use it to decide what to do - which is the same function that human’s brains do.

“Bees are known to perform very complex tasks considering the size of their brains and their simplicity compared to high-level organisms,” said Gill. “If we can focus on simple tissues and find the small changes that can have profound effects on behavior, it can give us a basis to start understanding how very small changes to that brain can do that.”

A swarm containing tens of thousands of bees descended on a man in Arizona who disturbed their nest, but he survived despite sustaining more stings than can be counted.
"The number of bees in the shed was unbelievable," DeSantis said. "The deputy who arrived said it was it was like something you’d see in the movies. It was just amazing."
Authorities said the man was working on the property when he was stung and ran to his vehicle, getting help from two passersby who were also stung. They were not hospitalized.
A beekeeper called to the scene was also stung 23 times. He told authorities it would probably take several days to fully contain the bees.

A brick wall at the Penn Brewery, not far from where I work, collapsed today during an attempt to get to a beehive said to have occupied space behind it "for years." No-one was hurt, and the local news reports that the bees are fine, too. Some of their honey may even find its way into a brew, if it's found to be of sufficient quality. I walked over and grabbed these photos of their handiwork.
The wall will be rebricked after a beekeeper removes the hive on Friday.
