00:00:01,920 --> 00:00:06,520
Speaker 1: Welcome to brain Stuff production of I Heart Radio. Hey,

2
00:00:06,600 --> 00:00:09,880
Speaker 1: brain Stuff, Lauren vocal bamb here. Did you know that

3
00:00:10,039 --> 00:00:13,640
Speaker 1: one bee has to fly approximately nine miles that's a

4
00:00:14,840 --> 00:00:18,440
Speaker 1: kilometers or about three times around the earth and gather

5
00:00:18,560 --> 00:00:21,680
Speaker 1: nectar from some two million flowers to make a mere

6
00:00:22,000 --> 00:00:25,120
Speaker 1: pound or half a kilo of honey. That's a lot

7
00:00:25,120 --> 00:00:28,320
Speaker 1: of work for just one little APIs malafera. So it's

8
00:00:28,320 --> 00:00:31,280
Speaker 1: a good thing that honeybees are well organized, task oriented

9
00:00:31,320 --> 00:00:35,040
Speaker 1: insects who stick together in huge families of several thousand

10
00:00:35,080 --> 00:00:39,000
Speaker 1: workers per hive. And did you know that the honeybee

11
00:00:39,080 --> 00:00:42,120
Speaker 1: is the only insect that produces food eaten by humans

12
00:00:42,640 --> 00:00:46,400
Speaker 1: and that honey never expires. Archaeologists have found pots of

13
00:00:46,440 --> 00:00:49,600
Speaker 1: still edible honey in ancient Egyptian tombs that are thousands

14
00:00:49,640 --> 00:00:53,560
Speaker 1: of years old. That's because honey is hygroscopic. It's great

15
00:00:53,600 --> 00:00:57,720
Speaker 1: at absorbing moisture, so it'll basically desiccate any bacteria or

16
00:00:57,720 --> 00:01:00,000
Speaker 1: mold that try to eat it. And it's a set

17
00:01:00,360 --> 00:01:02,840
Speaker 1: with a pH somewhere between three point five and four

18
00:01:02,880 --> 00:01:06,520
Speaker 1: point oh. It's about as acidic as orange juice. A

19
00:01:06,600 --> 00:01:10,400
Speaker 1: groundbreaking study led by biologists at the University of California,

20
00:01:10,440 --> 00:01:14,120
Speaker 1: San Diego consolidates scientific data from around the globe to

21
00:01:14,120 --> 00:01:17,240
Speaker 1: show that the honeybee is the most successful pollinator in

22
00:01:17,280 --> 00:01:20,440
Speaker 1: the world, the most important single species of pollinator in

23
00:01:20,520 --> 00:01:24,800
Speaker 1: natural ecosystems, and the single most frequent pollinator of naturally

24
00:01:24,800 --> 00:01:29,680
Speaker 1: occurring flowers and non crop plants on Earth. That's a

25
00:01:29,720 --> 00:01:33,480
Speaker 1: pretty big, vital deal for the planet and no small feet.

26
00:01:33,520 --> 00:01:35,920
Speaker 1: For creatures with a brain the size of a sesame seed,

27
00:01:36,400 --> 00:01:40,120
Speaker 1: they're amazing. B two B communication skills allow them to pipe,

28
00:01:40,280 --> 00:01:45,039
Speaker 1: that is, buzz, waggle or advance, and beard in order

29
00:01:45,080 --> 00:01:49,880
Speaker 1: to protect themselves and their life's mission making honey But

30
00:01:50,000 --> 00:01:52,040
Speaker 1: let's go back to that last one. What the heck

31
00:01:52,120 --> 00:01:54,880
Speaker 1: is bearding and why do honeybees do it? It's all

32
00:01:54,880 --> 00:01:58,640
Speaker 1: about keeping cool. Honey Bees are able to regulate the

33
00:01:58,640 --> 00:02:01,680
Speaker 1: temperature of their hive throughout year. In winter months, they

34
00:02:01,760 --> 00:02:04,920
Speaker 1: raise the hives temperature by huddling together and vibrating their

35
00:02:04,960 --> 00:02:08,040
Speaker 1: wings to generate body heat and keep warm. It's sort

36
00:02:08,080 --> 00:02:09,799
Speaker 1: of like if you were too jog in place or

37
00:02:10,000 --> 00:02:13,920
Speaker 1: rub your arms to warm up. But in the summer months,

38
00:02:13,960 --> 00:02:16,640
Speaker 1: the average temperature of the hive should be between ninety

39
00:02:16,639 --> 00:02:20,280
Speaker 1: and nine degrees fahrenheit that's thirty two thirty five celsius.

40
00:02:20,720 --> 00:02:22,880
Speaker 1: If it gets too hot, the bees will fan their

41
00:02:22,880 --> 00:02:26,280
Speaker 1: wings to lower the temperature and circulate air throughout the hive.

42
00:02:27,000 --> 00:02:29,960
Speaker 1: Sometimes they collect and place droplets of water inside the

43
00:02:30,000 --> 00:02:32,280
Speaker 1: hive and then queue up at the hives entrance and

44
00:02:32,360 --> 00:02:35,440
Speaker 1: fan their wings, creating air currents that evaporate the water

45
00:02:35,720 --> 00:02:38,880
Speaker 1: and push cool air inside. And while the fanners are

46
00:02:38,880 --> 00:02:41,720
Speaker 1: outside fanning, there are bees on the inside fanning as well.

47
00:02:43,360 --> 00:02:46,240
Speaker 1: In summer severely hot weather, when the temperatures rise to

48
00:02:46,280 --> 00:02:49,280
Speaker 1: extremes and the hives population is large and crowded due

49
00:02:49,280 --> 00:02:52,040
Speaker 1: to an abundance of nectar flow, the bees head and

50
00:02:52,240 --> 00:02:54,800
Speaker 1: mass out of the nest and cluster outside the hive

51
00:02:54,919 --> 00:02:58,079
Speaker 1: to try to remain cool and keep the hive from overheating,

52
00:02:58,280 --> 00:03:00,520
Speaker 1: which could kill the next generation of bees that are

53
00:03:00,560 --> 00:03:04,720
Speaker 1: growing or hatching. Busy bee activity inside the hive generates

54
00:03:04,760 --> 00:03:07,360
Speaker 1: a lot of heat, so they leave the hive and

55
00:03:07,440 --> 00:03:10,880
Speaker 1: cling to the outside. Then create even more airflow than

56
00:03:10,960 --> 00:03:15,320
Speaker 1: regular fanning by huddling together and beating their wings. This

57
00:03:15,400 --> 00:03:18,200
Speaker 1: activity is called bearding because the formation that the bees

58
00:03:18,240 --> 00:03:20,639
Speaker 1: make on the outside of the hive is shaped sort

59
00:03:20,680 --> 00:03:24,040
Speaker 1: of like a beard. It's a natural, normal behavior and

60
00:03:24,040 --> 00:03:26,720
Speaker 1: should not be confused with swarming, which occurs when the

61
00:03:26,760 --> 00:03:29,160
Speaker 1: bees all get together and decided to leave the hive

62
00:03:29,200 --> 00:03:33,000
Speaker 1: for greener pastures. So if you see a bunch of

63
00:03:33,000 --> 00:03:36,560
Speaker 1: bees in beard formation hanging outside their hive, have no fear.

64
00:03:36,960 --> 00:03:41,600
Speaker 1: Think of them as amazing Apien generators. Society of worrying

65
00:03:41,640 --> 00:03:44,160
Speaker 1: little porch fans buzzing up a breeze to try and

66
00:03:44,200 --> 00:03:51,960
Speaker 1: beat the heat inside. Today's episode was written by Carrie
