00:00:02,040 --> 00:00:07,000
Speaker 1: Welcome to brain Stuff from How Stuff Works, Hey, brain Stuff,

2
00:00:07,040 --> 00:00:11,000
Speaker 1: Lauren Vogebong. Here, you've probably seen stories about exemplary bravery

3
00:00:11,000 --> 00:00:14,160
Speaker 1: and battles soldiers and volunteers who risk everything to pull

4
00:00:14,200 --> 00:00:16,960
Speaker 1: injured compatriots out of harm's way so they can receive

5
00:00:17,079 --> 00:00:20,160
Speaker 1: much needed medical attention. But some of these heroes will

6
00:00:20,200 --> 00:00:23,040
Speaker 1: never receive any medals, parades, or commendations for their work,

7
00:00:23,640 --> 00:00:28,040
Speaker 1: not because of injustice, but because their ants, a species

8
00:00:28,080 --> 00:00:31,840
Speaker 1: called megapona analysis are termite hunting ants that scientists say

9
00:00:31,960 --> 00:00:35,400
Speaker 1: not only rescue injured comrades but also treat their wounds.

10
00:00:35,800 --> 00:00:38,800
Speaker 1: The survival rate among those injured in this combat is remarkable.

11
00:00:39,040 --> 00:00:43,000
Speaker 1: Up to These ants live in colonies in sub Saharan

12
00:00:43,040 --> 00:00:46,560
Speaker 1: Africa that average nearly one thousand members. The ants wage

13
00:00:46,600 --> 00:00:49,519
Speaker 1: war on termites, raiding their nests and dragging the dead

14
00:00:49,560 --> 00:00:52,840
Speaker 1: back behind the lines as a source of food. These raids, however,

15
00:00:52,960 --> 00:00:55,640
Speaker 1: often come at a heavy price. The termites bite and

16
00:00:55,680 --> 00:00:58,320
Speaker 1: crush the ants, ripping off limbs and snapping off heads.

17
00:00:59,280 --> 00:01:02,640
Speaker 1: Eric Frank, a scientists at the University of Lausan in Switzerland,

18
00:01:02,760 --> 00:01:04,920
Speaker 1: has studied these ants and seen them do battle with

19
00:01:05,040 --> 00:01:07,640
Speaker 1: termites at a research station in the Comaway National Park,

20
00:01:07,760 --> 00:01:10,240
Speaker 1: one of the largest protected areas in West Africa in

21
00:01:10,360 --> 00:01:13,560
Speaker 1: northern code Duvois. He would watch the ants drag the

22
00:01:13,600 --> 00:01:16,119
Speaker 1: injured back to their nest. But because the ants make

23
00:01:16,160 --> 00:01:19,080
Speaker 1: their homes underground, it was difficult to divine exactly what

24
00:01:19,160 --> 00:01:22,120
Speaker 1: happened next. So Frank and his team set out to

25
00:01:22,120 --> 00:01:25,840
Speaker 1: discover what was happening inside the nest. First, they captured

26
00:01:26,000 --> 00:01:28,840
Speaker 1: entire ant colonies and set them up in artificial nests.

27
00:01:29,280 --> 00:01:32,039
Speaker 1: They then hooked up infrared cameras to keep tabs on

28
00:01:32,080 --> 00:01:35,600
Speaker 1: the insects. The scientists also captured termites and then allowed

29
00:01:35,640 --> 00:01:38,880
Speaker 1: the ants to stage a raid. Many ants were gravely

30
00:01:38,920 --> 00:01:42,440
Speaker 1: injured during the melee, many lost limbs. They're able bodied.

31
00:01:42,480 --> 00:01:46,800
Speaker 1: Comrades responded by staging a battlefield triage, separating the gravely

32
00:01:46,800 --> 00:01:50,720
Speaker 1: wounded from the only slightly wounded. The seriously injured. Those

33
00:01:50,760 --> 00:01:53,080
Speaker 1: who lost at least five limbs often died on the

34
00:01:53,120 --> 00:01:56,560
Speaker 1: battlefield because, as the researchers noted, they didn't seem to

35
00:01:56,600 --> 00:01:59,280
Speaker 1: want to be helped. That bend and distort their bodies,

36
00:01:59,360 --> 00:02:01,440
Speaker 1: making it difficult halt for their sisters in arms to

37
00:02:01,560 --> 00:02:04,800
Speaker 1: carry them to safety. Those whose wounds were less serious, however,

38
00:02:04,840 --> 00:02:08,040
Speaker 1: allowed themselves to be cared for. Once back at the nest,

39
00:02:08,080 --> 00:02:10,200
Speaker 1: the healthy ants set up an aid station where they

40
00:02:10,200 --> 00:02:13,359
Speaker 1: tended to the wounded, licking their injuries. Ants who did

41
00:02:13,400 --> 00:02:16,440
Speaker 1: not receive this treatment had a chance of dying within

42
00:02:16,520 --> 00:02:19,480
Speaker 1: twenty four hours after the battle. Those who were treated

43
00:02:19,520 --> 00:02:22,560
Speaker 1: had a survival rate of up to and lived to

44
00:02:22,560 --> 00:02:24,959
Speaker 1: fight another day, to the benefit of the whole community.

45
00:02:25,520 --> 00:02:28,480
Speaker 1: Frank and his team theorized that the licking saves lives

46
00:02:28,680 --> 00:02:36,760
Speaker 1: by preventing the onset of infection. Today's episode was written
