Walmart just filed a patent for robot bees amid ongoing battle with Amazon
Amid an ongoing battle over the retail and grocery delivery market, Walmart has filed a patent for robotic bees that would pollinate crops just like the real insects.
Walmart has filed a patent for robotic bees that would pollinate crops just like the real insects.
The patent outlines how tiny autonomous “pollination drones” would use sensors to locate crops, transport pollen, and verify which crops have been successfully pollinated. It would be a significantly more efficient way to pollinate crops than crop dusting, the patent suggests.
In total, Walmart has filed six patents for drone farming technologies, including ones that would identify pests and monitor crop health. The retail giant has yet to comment on exactly how it plans to use the new technology, but it’s possible Walmart plans to start an agricultural operation, a move that could help expand its grocery business and lead to more control of its food supply chain.
It’s among the latest developments in the ongoing battle between Walmart and Amazon over retail and, more recently, groceries. In February, Amazon began offering free same-day grocery delivery service to its Prime members in select cities, and earlier this week Walmart announced plans to offer grocery delivery service in more than 800 of its stores for a flat rate of $9.95.
The bee drone technology, which was explored in season 3 of Black Mirror, could theoretically give Walmart an edge in food production over the long term.
The decline of honeybees poses a major threat to the world’s food supply. About one-third of the food we consume – fruits, vegetables, herbs, and spices – depends on pollination from honeybees, which make up only 2 percent of the total bee population.
What’s killing the bees is hard to say. But it’s likely been a complex interaction of multiple stressors: Lack of genetic diversity among their populations, a shortage of space for honeybees to roam, parasites and diseases, and pesticides. There’s also colony collapse disorder, a phenomenon where the majority of the worker bees disappear from the colony, though the number of collapses has gone down over the past few years.
Other organizations have already developed or drafted ideas for similar robot bee technologies, including a team at Harvard University, a researcher at Japan’s National Institute of Advanced Industrial Science and Technology, and a student at Savannah College of Art and Design in Georgia. No robot bee technology is currently being used on a large scale, however.
Walmart’s drone technology could boost food production if honeybee populations continue to dwindle in the decades to come. But some experts, like Quinn McFrederick, an entomologist at the University of California, think it’s better to spend resources protecting the real bees we have today.
“On top of more practical arguments, such as costs to smaller farms,” he told NPR, “I would not like to live in a world where bees are replaced by plastic machines. Let's focus on protecting the biodiversity we still have left.”

What makes an excellent educator?
- When it comes to educating, says Dr. Elizabeth Alexander, a brave failure is preferable to timid success.
- Fostering an environment where one isn't afraid to fail is tantamount to learning.
- Human beings are complicated and flawed. Working with those complications and flaws leads to true knowledge.

We all know sleeping with your ex is a bad idea, or is it?
- In the first study of its kind, researchers have found sex with an ex didn't prevent people from getting over their relationship.
- Instead of feeling worse about their breakup after a hookup, the new singles who attempted sexual contact with their ex reported feeling better afterwards.
- The findings suggest that not every piece of relationship advice is to be taken at face value.
It's hard to imagine such a number. But these images will help you try.

Tiny and efficient, these biodegradable single cells show promise as a way to target hard-to-reach cancers.
- Scientists in Germany have found a potential improvement on the idea of bacteria delivering medicine.
- This kind of microtargeting could be useful in cancer treatments.
- The microswimmers are biodegradable and easy to produce.
Metin Sitti and colleagues at the Max Planck Institute in Germany recently demonstrated that tiny drugs could be attached to individual algae cells and that those algae cells could then be directed through body-like fluid by a magnetic field.
The results were recently published in Advanced Materials, and the paper as a whole offers up a striking portrait of precision and usefulness, perhaps loosely comparable in overall quality to recent work done by The Yale Quantum Institute. It begins by noting that medicine has been attached to bacteria cells before, but bacteria can multiply and end up causing more harm than good.
A potential solution to the problem seems to have been found in an algal cell: the intended object of delivery is given a different electrical charge than the algal cell, which helps attach the object to the cell. The movement of the algae was then tested in 2D and 3D. (The study calls this cell a 'microswimmer.') It would later be found that "3D mean swimming speed of the algal microswimmers increased more than twofold compared to their 2D mean swimming speed." The study continues —
More interestingly, 3D mean swimming speed of the algal microswimmers in the presence of a uniform magnetic field in the x-direction was approximately threefolds higher than their 2D mean swimming speed.
After the 2D and 3D speed of the algal was examined, it was then tested in something made to approximate human fluid, including what they call 'human tubal fluid' (think of the fallopian tubes), plasma, and blood. They then moved to test the compatibility of the microswimmer with cervical cancer cells, ovarian cancer cells, and healthy cells. They found that the microswimmer didn't follow the path of bacteria cells and create something toxic.
The next logical steps from the study include testing this inside a living organism in order to assess the safety of the procedure. Potential future research could include examining how effective this method of drug delivery could be in targeting "diseases in deep body locations," as in, the reproductive and gastrointestinal tracts.
