Bees might just be the brainiacs of the insect world! These little buzzers are out there pulling off some seriously smart moves that'll make you do a double take. I'm talking about recognizing faces, using tools, making group decisions, and even doing a funky dance to chat with their buddies. It's like they've got their own secret society going on! And get this – they're not just buzzing around aimlessly. Nope, they're busy pollinating our crops and keeping our planet ticking. #brightside

FunTranscript
00:00So, it's amazing how smart bumblebees are.
00:03Despite having brains the size of a poppy seed, these little insects have incredible
00:08intelligence.
00:09Recently, researchers discovered that bees have emotions and might even be sentient.
00:15For example, they can show signs of anxiety in scary situations, like a simulated predator
00:20attack.
00:21They become hesitant and cautious, even avoiding perfectly safe flowers.
00:26This indicates they might have feelings similar to what we call emotions.
00:30They can also feel discomfort and pleasure.
00:34Scientists trained bees to associate colors with rewards and surprises.
00:38When the bees got a surprise treat, they acted happier and more resilient.
00:42Hey, don't you?
00:43They also put bees in situations where they had to choose between discomfort and rewards.
00:49The bees showed they could weigh the options and make decisions based on what they felt.
00:54This suggests they might experience discomfort just like we do.
00:59They can even display complex emotions, like optimism, frustration, and playfulness.
01:05And these are not the only surprises bees showed us.
01:09Bees are more than just honeymakers and pollinators.
01:12There are over 25,000 different species of bees worldwide, each with its own unique lifestyle.
01:19They live in a sensory world that's totally different from ours, seeing things in ultraviolet
01:24and polarized light.
01:26They can even sense the Earth's magnetic and electrical fields.
01:29This helps them figure out which flowers have already been visited by other bees.
01:34A big moment in bee evolution happened way back in the Jurassic period.
01:39Their ancestors decided to switch from wandering around to settling down in nests.
01:45This change required them to remember the location of their home base, or else they'd
01:49be in big trouble.
01:51So their brains adapted, and certain areas grew larger and more complex to handle all
01:56the new information.
01:58And now, millions of years later, they've turned into incredibly smart creatures.
02:03They can even solve math puzzles.
02:05Boy, I could've used some bees in middle school!
02:09Yeah, that's right, bees seem to grasp the concepts of addition and subtraction.
02:15Researchers set up special math mazes shaped like the letter Y for the bees to navigate.
02:21Instead of using numbers or symbols, which bees can't understand, they used colors.
02:26Blue meant add one, and yellow meant subtract one.
02:31The bees had to choose the right path based on the colors they saw at the beginning of
02:35the maze.
02:37After some training, where the bees completed a hundred trips through the mazes, they seemed
02:42to get the hang of it.
02:43Then came the test.
02:45The little insects got the correct answer more often than not, better than what you
02:49would expect by chance.
02:51This doesn't mean bees are doing complex math in their heads, but they might have flexible
02:56brains that can learn new tasks, even if they don't use them in the wild.
03:01They also showed an understanding of the concept of zero.
03:06Scientists trained them to recognize the smaller of two numbers.
03:09They showed the bees pictures with different numbers of shapes, rewarding them with sweet
03:14sugar water if they chose the picture with fewer shapes.
03:17But if they went for the picture with more shapes, they got a bitter taste of quinine.
03:22Yuck.
03:23Once the bees got the hang of it, the researchers introduced a new option – a blank picture
03:29with no shapes at all.
03:31And the bees chose the empty picture over images with two or three shapes almost half
03:35the time.
03:37This suggests that they understood that zero means less than two or three.
03:42In further tests, the bees showed they could tell the difference between one and zero.
03:47This might help them keep track of predators or find food sources more efficiently.
03:52And if bees can understand zero, who knows how many other animals out there can do the
03:57same!
03:59Not only can bees learn and remember new things, but they can also teach these things to each
04:04other, just like we do.
04:06Scientists set up a tricky puzzle box in a lab and trained some bumblebees to solve it.
04:11First, expert bees figured the puzzle out.
04:14Then they taught their clueless buddies how to crack it.
04:18Turns out, not only humans can pass on knowledge in this way.
04:22In another experiment, bees were given a puzzle to solve over several days.
04:27Despite having plenty of time to crack it, they couldn't do it without a little human
04:32help.
04:33But once they saw the solution, they were quick to catch on.
04:36It's also discovered that if there's a super genius bee in the group, its clever
04:41ideas might stick around and shape their societies for generations, surprisingly similar
04:47to humans'.
04:48Even behaviors we thought were purely instinctive, like the famous honey dance, seem to be influenced
04:54by social learning.
05:05Bees can even be taught to use tools, a skill previously thought to be limited to certain
05:10mammals, birds, and other creatures.
05:12They devised a test where bees had to move a tiny ball to the center of a platform to
05:17get a sweet reward.
05:19Bees don't do stuff like this in the wild, so biologists had to teach them.
05:25Using a plastic bee on a stick, the researchers demonstrated the task to the bees.
05:30After a few days of training, the bees began dragging the ball to the center all by themselves.
05:37And once again, they showed other bees how to do it.
05:40What's interesting is that they didn't just copy blindly.
05:44When faced with new situations, they improved on what they had learned, choosing the most
05:48efficient route to success.
05:51For instance, when given a choice between different colored balls, the bees picked the
05:55one closest to the center, even though they had been trained with different conditions.
06:00This shows that bees aren't just following instructions, they're thinking and adapting
06:05to new challenges.
06:08We used to think of bees as a homogeneous workforce.
06:11It's a huge hive mind where everyone is tirelessly serving their queen.
06:16But this view is also being challenged by fascinating new research.
06:21Turns out, honeybees have distinct personalities.
06:24For example, some bees are more adventurous, while others prefer to stay close to the hive.
06:30A small percentage of bees, known as nest scouts, exhibit a thrill-seeking behavior
06:35by venturing out in search of new hive locations.
06:39These brave scouts are not only more likely to seek out new nest sites, but also to engage
06:44in food scouting.
06:46And there are huge differences in gene activity in the brains of scouting bees compared to
06:51their non-scouting counterparts.
06:53The brains of scout bees showed heightened activity in reward systems.
06:58That's where their preference for novel experiences comes from.
07:01It's very similar to novelty-seeking behavior in humans and other animals.
07:06Sometimes, their personalities are even shaped by their memories and previous experiences.
07:12Some bees even showed signs of PTSD.
07:15So in the hive, bees choose their jobs based on their personality traits.
07:22They can also be trained to detect any smell.
07:25They have a huge sensitivity to volatiles, and thanks to that, they can even detect diseases.
07:31Bees were trained to associate the scent of infected samples with a sugar water reward.
07:37With repeated exposure, the bees quickly learned to extend their tongues in response to the
07:41scent alone, without the need for a reward.
07:45Thanks to that, they were able to detect infected samples within seconds.
07:50This worked with both mink and human samples.
07:53They showed very accurate results in distinguishing between infected and healthy samples.
07:58Now we're trying to scale up this innovative approach and develop prototypes of machines
08:04capable of automatically training multiple bees simultaneously.
08:08This technology has the potential to serve as an effective diagnostic system, especially
08:14in low-income countries.
08:17And there are many more things bees can do.
08:19They can learn while sleeping, which means they can dream and see dreams of things they
08:24saw during the day.
08:26They can also remember human faces.
08:28They memorize unique features and can recognize them through repeat interactions.
08:33In one study, scientists paired images of human faces with sugar water and found that
08:39bees recognized and remembered faces associated with the sweet reward, even when the reward
08:45was absent.
08:46This also helps them to recognize each other and return to flowers that produce more pollen.
08:52So what does this mean for us?
08:54Well, if it's true that bees actually feel emotions and have some sort of sensations,
08:59this changes how we should treat them.
09:01They're already an endangered species.
09:03Now we should treat them with much greater care.
09:07So be careful around the bees!
09:12That's it for today!
