Drones to airdrop hundreds of thousands of mosquitos to fight disease

One approach to fight mosquito-borne diseases is to introduce huge numbers of sterilized male mosquitos to beat out the wild males in competition for female mosquitos. The challenge is that it’s expensive to airdrop the mosquitos from airplanes and often difficult to traverse developing nations by ground. Now, WeRobotics has prototyped a drone that carries hundreds of thousands of mosquitos and releases them at just the right moment. The first experiments in South or Central America will take place in the next few months. From IEEE Spectrum:

The goal is to pack as many mosquitoes as possible into the drone. However, clumping is a problem because the insects form “a big collection of legs and wings,” he says. The trick, according to Klaptocz, is to keep them inside a precooled container: “Between 4 °C and 8 °C, they’ll fall asleep, and you can pack them up fairly densely.”

It’s also important to control the release of the mosquitoes, rather than dumping them out all at once. “We tried different systems to get the mosquitoes out of the holding canister, including vibrations and a treadmill,” he says. “Right now, we’re using a rotating element with holes through which individual mosquitoes can fall.” Once the mosquitoes fall out of the canister, they spend a few seconds in a secondary chamber warming up to the outside air temperature before exiting the drone, to make sure they’re awake and ready to fly.

Problems that Plagued an Edible Marble Machine

Prolific creator [Martin Raynsford] recently created a plus-sized edible version of his laser-cut Marble Machine for a Cake International exhibit and competition; it seemed simple to do at first but had quite a few gotchas waiting, and required some clever problem-solving.

Gears are three layers, stacked and cemented with sugar glue, and coated with a hard edible shine.

The original idea was to assemble laser-cut gingerbread parts to make the machine. Gingerbread can be laser-cut quite well, and at first all seemed to be going perfectly well for [Martin]. However, after a few days the gingerbread was sagging badly. Fiddling with the recipe and the baking was to no avail, and it was clear [Martin] needed to find something other than gingerbread to work with. After experimenting, he settled on a modified sugar paste which kept its shape and dried hard enough to work with. (While appearing to stretch most people’s definition of “cake” past the breaking point, the category [Martin] entered in the competition allows it.) The parts were cut by hand using laser-cut wood parts as a guide, then finished in a food dehydrator overnight.

The next problem was how to create the large spiral which forms the main ramp. The answer was to laser-cut a custom support structure that supported the piece while it dried out, and doubled as a way to transport the piece safely. High stress points got extra layers cemented with sugar glue, and some parts were reinforced internally with strands of uncooked spaghetti. Everything was sealed with an edible shine, which [Martin] says acts as a kind of varnish for cakes. A video demonstration is embedded below.

It’s nice to see the work paid off, especially since the first version (with gingerbread) was close but ultimately proved to be a dead-end, and there were multiple other problems to overcome. We’re sure the Edible Marble Machine raised some eyebrows, though perhaps not quite as many as the also-edible-but-somewhat-bizarre Vin Diesel Ham Sandwich.

The More Emo You Are, The Better Your Chances

Intelligence is highly priced anywhere you go. People with high IQ are often sought after in the working world and well thought of. In the past, intellectual ability (IQ) seemed to be the determining factor for whether a person was selected in top schools or at big corporations. These days however, emotional intelligence has risen in rank and could almost, if not, be more important in determining one’s potential.

Simply putting, is it good to only be book smart, or is it better to be street smart? What kind of intelligence will actually help you survive well in today’s cut throat society? More and more jobs and industries are valuing emotional intelligence over technical or intellectual capabilities because this is how management sieves out the crème de la crème.

So if emotional intelligence (EI) is so valued, wouldn’t you want to know where you stand on the scale? In fact, unlike IQ, EI can be learned and improved over time. So try this test to see where you stand.

What Is Emotional Intelligence?

The Global Emotional Intelligence Test (GEIT) is based on Daniel Goleman’s four quadrant Emotional Intelligence Competency Model (2002).

Emotional intelligence is the ability to recognise, understand and manage emotions in ourselves and others. Goleman divides Emotional Intelligence into four clusters or quadrants known as of Self-Awareness, Self-Management, Social Awareness and Relationship Management (also popularly known as “people skills”).

To read in detail what each cluster reflects after you have completed the test, click here.


The GEIT uses 40 questions which are derived from the Global EI Capability Assessment instrument, which contains 158 items.

The GEIT, is a forced-choice psychological test which requires you to chose one statement in each pair of statements that describes you best. For each pair of statements, select the statement that best applies to you. It usually takes about 10 minutes to complete the test.

Why is Emotional Intelligence Important?

Goleman’s (1998) findings indicated that Emotional Intelligence contributes 80 to 90% of the competencies that distinguish outstanding leaders from average leaders. Some of the behaviors identified include:

– The ability to recognise and understand their own moods, emotions and drives as well as their effect on others;

– The ability to control or redirect disruptive impulses, moods and to think before acting;

– The passion to work for reasons beyond money or status and the propensity to pursue goals with energy and persistence;

– The ability to understand the emotional makeup of other people and the skill in treating people according to their emotional reactions; the proficiency in managing relationships, building networks and the ability to find common ground and build rapport.

You Can Train Up Your EI but Not Your IQ

In professional and technical fields, the typical entry-level threshold IQ is 110 to 120. It is generally considered that your IQ, which is largely genetic, will change little from childhood. Since everyone is in the top 10% or so of intelligence, IQ itself offers relatively little competitive advantage.

EI on the other hand can be learned at any age. Growing your competency in EI is not easy or quick, as it takes perseverance in the process of critical self-evaluation, commitment to improvement and of course behavioural practice. It is also important to note, that competence in Emotional Intelligence does not necessarily increase with age as you might expect. Some people may learn from life’s experiences, but many do not.

By taking the GEIT, you will have better awareness of where you stand with your EI and this will serve as a guide to which EI areas you are doing well in and those which perhaps you need to focus on for development.

Take the Global Emotional Intelligence Test here.

How to Escape from Dangerous Forest Animals

Observing animals in the wild can be a great experience, but an encounter with a wild animal can turn dangerous quickly. Many wild animals in the forest will attack humans if provoked. The best way to avoid an attack from a forest animal is to leave them alone. However, if you do find yourself in a dangerous situation, there are some tactics you can use to escape and get to safety.



  1. Look at the color of the bear’s fur. It’s important you determine what kind of bear you’re dealing with. The way you respond to a black bear encounter will be very different than a brown bear encounter.[1]

    • If the bear has black fur, it’s a black bear. Full-grown black bears are usually smaller than brown bears.
    • If the bear has brown fur, it’s a brown bear. Brown bears also have a pronounced hump between their shoulders that black bears don’t have. Grizzly bears are a subspecies of brown bear.
  2. Let the bear know you’re a human and not prey. Speak in a low, calm voice and wave your arms slowly. Do not scream or make any high-pitched noises or you could agitate the bear.[2]
    Escape from Dangerous Forest Animals Step 2 Version 2.jpg
  3. Slowly move away from the bear sideways. Don’t take your eyes off the bear. Moving sideways will prevent you from tripping. Do not run. Bears can run faster than humans and they enjoy chasing their prey. If the bear starts to follow you, stop moving.[3]

  4. Never approach a female bear with her cubs. Female bears are extremely defensive of their cubs, and they’re more likely to attack humans.[4]

  5. Play dead if you’re attacked by a brown bear. Get on the ground and lay flat on your stomach. Clasp your hands together behind your neck. Spread apart your legs so it’s harder for the bear to flip you over. Wait for the bear to lose interest and leave.[5]

    • If the bear doesn’t stop attacking you, reach for a nearby rock or branch and fight back. Hit the bear in the face as hard as you can repeatedly.
  6. Run if you’re attacked by a black bear. Do not play dead if a black bear attacks you. Try to find shelter in a nearby car or building. If you can’t escape, hit the bear in the face repeatedly with any nearby objects.[6]

EditWild Cats and Wolves

  1. Make yourself appear larger to intimidate the wild cat or wolf. Wave your arms over your head. Unzip your jacket and open it so you seem bigger.[7]
    Escape from Dangerous Forest Animals Step 7 Version 2.jpg
  2. Speak in a confident, low voice. Don’t scream or make any high-pitched noises. Speaking in a low voice will show the wild animal you’re a human and not prey.
    Escape from Dangerous Forest Animals Step 8 Version 2.jpg
  3. Remain calm and back away slowly. Do not turn away and run or you could trigger the animal to attack. Maintain eye contact with the animal as you’re backing away.[8]
    Escape from Dangerous Forest Animals Step 9 Version 2.jpg
  4. Never crouch down or bend over to pick something up. This will make you look small and weak to wild cats and wolves. Maintain an upright standing position so the animal knows you’re a human and not prey.[9]
    Escape from Dangerous Forest Animals Step 10 Version 3.jpg
    • If you’re with children, it’s important that you pick them up without crouching down or bending over. Reach your arms down to grab them without lowering your body.[10]
  5. Throw things in the direction of the animal. Only do this if you can reach rocks or branches without having to crouch, bend over, or turn away. You don’t need to aim for the animal itself. You’re just trying to scare it off by throwing things near it.[11]
    Escape from Dangerous Forest Animals Step 11 Version 2.jpg
    • If a wild cat or wolf approaches you, start throwing things directly at it.
  6. Fight back if the animal attacks you. Try to remain standing as wild cats and wolves will most likely try to bite your head and neck. Use any tools you have available to hit the animal in the head, including nearby rocks and branches. If you have nothing to fight with, use your fists. Continue beating the animal as hard as possible until it flees.[12]
    Escape from Dangerous Forest Animals Step 12 Version 2.jpg


  1. Be mindful of where you place your hands and feet. Watch the path in front of you as you’re walking. Look at tree branches and trunks before you grab onto them. If you see a snake, stop immediately.
    Escape from Dangerous Forest Animals Step 13 Version 2.jpg
    • Assume any snake you encounter in the wild is poisonous.
  2. Quickly back away from the snake. Don’t try to step over the snake or move it out of your way. Snakes can strike a distance that is half the length of their body, so make sure you’re far away from the snake before you try to go around it.[13]
    Escape from Dangerous Forest Animals Step 14 Version 2.jpg
  3. Don’t try to suck the venom out if you’re bitten. You can’t suck snake venom out with your mouth. Instead, focus on seeking help.
    Escape from Dangerous Forest Animals Step 15 Version 2.jpg
  4. Seek help immediately if you’re bitten. Call emergency services if you have service and let them know your location. If you don’t have service, find someone with a phone or vehicle that can get you to a hospital.[14]
    Escape from Dangerous Forest Animals Step 16 Version 2.jpg
    • Try to get a good look at the snake that bit you. It will help the hospital treat your wound faster if they know what kind of snake bite it is.
  5. Keep the bitten area below your heart if possible. If you were bitten on your arm or leg, don’t lift them above your heart.[15]
    Escape from Dangerous Forest Animals Step 17 Version 2.jpg

EditStaying Safe

  1. Be aware of your surroundings. Don’t wear headphones or look down at your phone screen when you’re walking through the forest. Keep your head up and pay attention to what’s going on around you. You’re less likely to startle a wild animal if you notice them from a distance first.
    Escape from Dangerous Forest Animals Step 18 Version 2.jpg
  2. Keep an eye out for animal tracks. If you see tracks, be on alert for nearby animals. If the tracks are heading in the same direction you’re walking in, change directions or turn back.
    Escape from Dangerous Forest Animals Step 19 Version 2.jpg
  3. Keep your distance if you see an animal. Never approach wild animals or attempt to feed them. If you encounter an animal, appreciate from a distance that you’re getting to see them in their natural environment. Most wild animals are just as afraid of humans as you are of them, and they won’t attack unless provoked.[16]
    Escape from Dangerous Forest Animals Step 20 Version 2.jpg
  4. Remain calm if an animal notices you. Don’t scream or make high-pitched noises. Avoid running away or you could trigger the animal to chase you. Calmly back away from the animal until it’s out of sight.[17]
    Escape from Dangerous Forest Animals Step 21 Version 2.jpg
  5. Don’t bother baby animals. Never approach a baby animal in the wild, even if it appears to be alone. The baby animal’s mother is likely nearby. Wild animals are more likely to attack if they perceive you as a threat to their babies.[18]
    Escape from Dangerous Forest Animals Step 22 Version 3.jpg
    • If you’re really worried about a baby animal, leave the area and contact a park ranger or local official.
  6. Keep your food away from wild animals. Never feed animals in the wild. Don’t litter food scraps in the forest or you could attract wild animals. If you eat something while you’re camping or hiking, pack any food scraps or trash in your backpack and carry it with you. You can also put food waste in a trash bag and tie the bag to a high tree branch.
    Escape from Dangerous Forest Animals Step 23 Version 3.jpg
  7. Stay on the trail when you’re hiking. Look for trail markers so you don’t accidentally wander off the trail. Wild animals are less likely to be on trails because of all the foot traffic.
    Escape from Dangerous Forest Animals Step 24 Version 2.jpg
  8. Be mindful of other dangerous animals. Watch out for fire ants and bee hives. Avoid swimming in areas with alligators. Know what to do if an elephant charges at you in the forest. Staying alert and being prepared will keep you safe in most encounters with wild forest animals.
