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.”
Today we go to a future where animal products are banned. It’s one that lots of listeners have asked for so here you go. We talk about what happens to the land, the animals and the humans in this equation.
In this episode we discuss the arguments in favor and against banning meat. How does that impact culture? Why should we do it? Does it help or hurt the environment? Can you really grow meat in a lab? And is that meat vegan?
The FarmBot Genesis is an open-source robot gardener for home food production. You design your mini-farm with their app and then the Raspberry Pi-powered robot handles the rest, from planting to watering, weeding to harvesting. The FarmBot Genesis sounds like the evolutionary descendant of Ken Goldberg and Joseph Santarromana's groundbreaking 1994 telerobotic artwork, the TeleGarden:

The New York State Department of Health is selecting companies that may be given license to grow weed on farmland in Bethel, New York adjacent to the site of the legendary Woodstock Music Festival of 1969. Put that in your pipe and smoke it! Read the rest
Joe sez, "There's a new FDA rule that will make it nearly make it financially impossible for small craft brewers to give their grain away to farmers for animal feed. I work for a small brewery and all of us there are very upset about this and the general disregard for sustainability. At the end if the article linked there's direct FDA links that cover their proposal."
Leftover brewing grains have been fed to livestock since the dawn of agriculture, so this is a pretty radical shift. The proposed new requirements for animal feed handling stipulate that the feed has to be dried, analyzed and packaged before being donated to farmers (the spent grains are generally given away at the end of the brewing process), at substantial expense.
It's clear that food safety is important, but I'm not convinced that the stringency of this rule is commensurate with the risk. Read the rest
Underground the city of London are eight massive bomb shelters like the one pictured above that have been empty or used as document storage for more than 50 years. Now, one of them is being transformed into a subterranean farm. The farming group, called Zero Carbon Food, based their system on hydroponics and LED light powered by wind-generated electricity.
"When I first met these guys I thought they were absolutely crazy, but when I visited the tunnels and sampled the delicious produce they are already growing down there I was blown away," says two Michelin star chef Michel Roux Jr.
In Idaho, the dairy industry has successfully lobbied lawmakers to propose a new law that would make it a crime for animal rights advocates or journalists to lie about their backgrounds to applications at dairy farms, for the purpose of documenting criminal activity or animal abuse.
Striking back at this proposed legislation that would curb free speech, Los Angeles-based nonprofit Mercy for Animals today released video of a dairy worker sexually abusing a cow at Dry Creek Dairy (owned by Bettencourt Dairies) in Idaho. Read the rest
A maple tree sapling with its crown cut off is "like a sugar-filled straw stuck in the ground." That's what researchers at the University of Vermont’s Proctor Maple Research Center discovered when they applied vacuum pressure to the stump of a sugar-maple sapling. They were able to draw out an astonishing amount of sap from the trunk this way.
Typically, a traditional sugarbush produces about 40 gallons of maple syrup per acre of forest by tapping, perhaps, 80 mature trees. With this new method, the UVM researchers estimate that producers could get more than 400 gallons of syrup per acre drawing from about 6,000 saplings.

This happened in my friend's henhouse this morning.
My friend Kate Hastings, who took this photo, thinks this egg froze because the hen cracked it slightly. But it also looks like the kind of expansion cracking that you can get when eggs freeze and burst their own shells. When the water in the egg white and yolk freezes, it forms a crystalline structure — and that structure isn't very tightly packed. There's lots of space between the molecules, which means that solid ice takes up more space than the liquid it replaced. If the egg freezes solid enough, it's got nowhere left to expand except outside the shell.
Eggshells, as it turns out, are not a great insulator from the cold. Chicken butts are, but chickens also don't always sit on their eggs consistently enough to keep those eggs from freezing.
One side note: You can actually thaw and eat frozen eggs. But you shouldn't thaw and eat an egg like this. That's because the shell is actually a pretty good barrier against bacteria. If a fresh egg — the kind sitting under a hen — has cracked, there's a higher likelihood of bacterial infiltration.
