Could Pollinator Drones Soon Replace Bees? alayham Sat, 05/06/2017 - 18:13

Scientists in Japan have created tiny drones that pollinate plants; and if bees disappear, the insect-size drones are intended to replace them.
Right now the drones are not autonomous, and they’ve never been tested outside the lab. But they might one day be a necessity. In recent years, bee populations have sharply declined, and bee deaths have been blamed on everything from pesticides to diseases to climate change. The results of a Greenpeace investigation published in the fall of 2016 reveal that unpublished field trials by pesticide manufacturers show that their products cause severe harm to honeybees at high levels. [1]
But why switch to organic farming when you can just build exorbitantly priced robots?
Eijiro Miyako, chemist from the National Institute of Advanced Industrial Science and Technology (AIST) in Japan, found the perfect substance for pollen collection in a decade-old bottle of sticky gel from an earlier experiment he stumbled across while cleaning his lab. The substance, an ionic liquid gel, consists of a collection of complex molecules linked in long chains, and it has the optimal stickiness to pick up pollen grains.
Miyako’s group rubbed the sticky gel on ants and flies – other types of pollinators – and put them on flowers. Each bug was soon covered in pollen.
For use with drones, the gel is a dual-purpose substance: It collects and deposits pollen, and also interacts with light waves to camouflage the drones. The camouflage could come in handy in the future as protection against predators if such drones were deployed in swarms. [1], [2]

The team then assembled a 1.6-by-1.6-inch remote-controlled drone equipped with tiny hairs similar to the hairs found on bees. Miyako coated the hairs with the gel and flew the drone into the flowers of Japanese lilies. The tiny robot picked up pollen like a natural pollinator. When it was directed to another flower to release the pollen grains, it successfully pollinated the plant just as the researchers hoped it would. [1]

Being able to use drones to assist pollinators is little more than a pipe dream at this point. Researchers know they work, but there are major hurdles that need to be cleared. Trevor Weatherhead, Executive Director of the Australian Honey Bee Industry Council, says:

“This little machine will certainly pollinate, but how many would you need for, say, 1,000 acres? You have your pumpkins and watermelons where the flowers are in under the leaves themselves, and the bees sort of fly in under – I’m not sure how the robots would be able to get in and out.” [2]

If you’re wondering why scientists don’t focus more attention on saving the bees instead of potentially replacing them with robots, you’re not the only person asking that question. Biologist David Goulson from the University of Sussex in the UK, wrote in his blog on February 7, 2017 that we should “look after [bees], not plan for their demise.” [3]
He added:

“I would argue that it is exceedingly unlikely that we could ever produce something as cheap or as effective as bees themselves. Bees have been around and pollinating flowers for more than 120 million years; they have evolved to become very good at it. It is remarkable hubris to think that we can improve on that. Consider just the numbers; there are roughly 80 million honeybee hives in the world, each containing perhaps 40,000 bees through the spring and summer. That adds up to 3.2 trillion bees. They feed themselves for free, breed for free, and even give us honey as a bonus. What would the cost be of replacing them with robots?”

Miyako says he wants to lower the cost of the drones, and he’s going to have to. If conservationists used the same drones that Miyako did, that would equal up to $100 dollars per bee. Honeybee hives contain tens of thousands of bees – a hive of 50,000 bees would cost $5 million to replace.

These 7 Turmeric Brands are Being Recalled Due to Lead Contamiantion

These 7 Turmeric Brands are Being Recalled Due to Lead Contamiantion alayham Fri, 08/12/2016 - 13:01

There are now 6 more brands of turmeric being recalled due to lead contamination. So far, there have been no illnesses or injuries reported from the high lead levels in the turmeric, but Gel Spice, Inc., the company expanding the recall, is taking precautions.
The FDA lists the following products as being recalled due to potential lead contamination:

The FDA’s website also provides pictures of the products for those who are unsure whether or not one that they own is on the list. Those who are concerned or have questions about the recall can contact Gel Spice, Inc. at (201) 564-0435. They are available to speak to consumers from 8am to 4pm Eastern Standard Time (EST).
The agency currently advises anyone who has these products to throw them away immediately and refrain from use.
The recall is an expansion of a previous recall:

“Gel Spice, Inc. is recalling one lot of Fresh Finds Ground Turmeric Powder because the product contains elevated lead levels.
The recalled ‘Fresh Finds Ground Turmeric’ is packaged in 3.75 oz. PET jars. It has a code of B/B 03/08/19 and B/B 05/18/19 on the neck of the container. The package also has a UPC code of 81026-01230. The product was distributed at Big Lots Stores throughout the United States.”

The Dangers of Lead Exposure

Lead poisoning from the ground turmeric can be potentially very serious if action is not taken. It is most dangerous in pregnant women, young children, the elderly and frail, and those with compromised immune systems.
Healthline documents the following symptoms of repeated lead exposure:

abdominal pain
abdominal cramps
aggressive behavior
constipation
sleep problems
headaches
irritability
loss of developmental skills in children
loss of appetite
fatigue
high blood pressure
numbness or tingling in the extremities
memory loss
anemia
kidney dysfunction

Children who have been exposed to lead over a long period of time may develop intellectual disabilities. While it is unlikely for this to occur after one instance of exposure to lead, parents are still cautioned to be vigilant.
If you think you or your child has been exposed to lead through the contaminated turmeric, contact your doctor immediately. He or she will advise a blood test to determine the levels of lead in your blood and determine whether or not you need further treatment.
