WEBVTT

1
00:00:00.080 --> 00:00:03.359
<v Speaker 1>We love these strange stories, these strange science stories. So

2
00:00:03.520 --> 00:00:04.799
<v Speaker 1>let's kick that off, shall we.

3
00:00:06.320 --> 00:00:14.160
<v Speaker 2>Strange science, It's like weird science, but strange.

4
00:00:15.160 --> 00:00:18.440
<v Speaker 1>I'm gonna say this amino acid wrong, but that's what

5
00:00:18.480 --> 00:00:21.120
<v Speaker 1>we do during strained science is mispronounced things just to

6
00:00:21.160 --> 00:00:24.519
<v Speaker 1>get to get your anger up. B tain b taine

7
00:00:24.640 --> 00:00:27.399
<v Speaker 1>b E t ai n E b tane a modified

8
00:00:27.440 --> 00:00:31.079
<v Speaker 1>amino acid that plays an important role when it comes

9
00:00:31.120 --> 00:00:34.920
<v Speaker 1>to metabolism. And btaine is a molecule that's made by

10
00:00:34.960 --> 00:00:38.359
<v Speaker 1>your kidneys. It's also found in some foods, and they're

11
00:00:38.399 --> 00:00:42.759
<v Speaker 1>saying it can produce a bunch of benefits just like

12
00:00:43.280 --> 00:00:48.159
<v Speaker 1>exercise does, and can slow some signs of aging, at

13
00:00:48.240 --> 00:00:49.880
<v Speaker 1>least when you feed it to mice. We don't know

14
00:00:49.920 --> 00:00:52.479
<v Speaker 1>if it happens to humans, but it's worth the shot, right.

15
00:00:52.759 --> 00:00:57.719
<v Speaker 1>There's a new study that came out in the magazine

16
00:00:57.880 --> 00:01:03.159
<v Speaker 1>or journal Sell that shows consistent exercise does raise levels

17
00:01:03.200 --> 00:01:05.760
<v Speaker 1>of that compound of btane, at least in young men.

18
00:01:05.799 --> 00:01:08.280
<v Speaker 1>That study also found that feeding that betaane to the

19
00:01:08.359 --> 00:01:12.400
<v Speaker 1>aged mice boosts their immune health and their grip strength.

20
00:01:13.760 --> 00:01:16.879
<v Speaker 1>How do you study the grip strength of a mouse?

21
00:01:18.680 --> 00:01:22.280
<v Speaker 1>For now, obviously there's nothing that can replicate the actual

22
00:01:22.359 --> 00:01:26.959
<v Speaker 1>benefits to your body of just doing the exercise. Exercise

23
00:01:27.000 --> 00:01:30.400
<v Speaker 1>itself sharpens the mind. It can smooth and sooth i

24
00:01:30.400 --> 00:01:35.319
<v Speaker 1>should say inflammation. It can help your cells damage, repair

25
00:01:35.400 --> 00:01:39.439
<v Speaker 1>damaged tissue, keeps some diseases at bay, or at least

26
00:01:39.480 --> 00:01:42.719
<v Speaker 1>at the very least eases some of their symptoms. But

27
00:01:42.879 --> 00:01:47.000
<v Speaker 1>this deep level molecular mechanism as to why it works

28
00:01:47.040 --> 00:01:50.560
<v Speaker 1>is still not fully clear. So a group out of China,

29
00:01:50.599 --> 00:01:54.200
<v Speaker 1>the Chinese Academy of Sciences, enlisted the aid of thirteen

30
00:01:54.719 --> 00:02:00.000
<v Speaker 1>healthy young men to lounge about for forty five days.

31
00:02:00.000 --> 00:02:02.239
<v Speaker 1>It's really hard to do, isn't it. Yeah, sure, it

32
00:02:02.319 --> 00:02:06.319
<v Speaker 1>was lounge about for forty five days, limit their physical activity,

33
00:02:06.799 --> 00:02:09.800
<v Speaker 1>and then have them run five.

34
00:02:09.639 --> 00:02:11.400
<v Speaker 2>K's every one or two days.

35
00:02:11.439 --> 00:02:13.400
<v Speaker 1>And the researchers would take the blood and the stool

36
00:02:13.439 --> 00:02:16.080
<v Speaker 1>samples from these guys and they would do a bunch

37
00:02:16.120 --> 00:02:19.000
<v Speaker 1>of measurements on them after their forty five day rest

38
00:02:19.039 --> 00:02:22.080
<v Speaker 1>and then twenty five days into their new running routine,

39
00:02:22.639 --> 00:02:26.919
<v Speaker 1>and they said that they found the exercises were reshaping

40
00:02:26.919 --> 00:02:29.960
<v Speaker 1>the body at a molecular level. After twenty five days

41
00:02:30.000 --> 00:02:33.199
<v Speaker 1>of regular running, there were changes in immune cells in

42
00:02:33.280 --> 00:02:37.280
<v Speaker 1>lipid metabolism in the gut microbiome, et cetera, but that

43
00:02:37.360 --> 00:02:41.039
<v Speaker 1>the biggest change was the abundance of that amino acid

44
00:02:41.120 --> 00:02:45.560
<v Speaker 1>that btane, and following up on those results, they then

45
00:02:45.680 --> 00:02:50.960
<v Speaker 1>started feeding btaane to mice. Old mice that drank water

46
00:02:51.080 --> 00:02:54.680
<v Speaker 1>spiked with btain had stronger muscles, less inflammation, and more

47
00:02:54.719 --> 00:02:58.599
<v Speaker 1>youthful skin than their counterparts who did not get the supplement. Again,

48
00:02:58.840 --> 00:03:00.960
<v Speaker 1>still no answer as to how they were able to

49
00:03:01.719 --> 00:03:05.439
<v Speaker 1>test the grip strength of a mouse. There's a new

50
00:03:05.439 --> 00:03:09.479
<v Speaker 1>study also into spiders that says the female when you

51
00:03:09.560 --> 00:03:12.759
<v Speaker 1>look at a species of spider where the female eats

52
00:03:12.840 --> 00:03:17.639
<v Speaker 1>the male after sex, that the males are pretty picky

53
00:03:17.639 --> 00:03:21.159
<v Speaker 1>about who it is they go. Afore, scientific studies spent

54
00:03:21.400 --> 00:03:24.520
<v Speaker 1>an ordinate amount of time and effort to demonstrate something

55
00:03:24.560 --> 00:03:27.039
<v Speaker 1>that is rather obvious, and in this case, they have

56
00:03:27.240 --> 00:03:33.400
<v Speaker 1>done it again. This one specifically is looking at cooi

57
00:03:33.520 --> 00:03:38.280
<v Speaker 1>males and seductive females in the sexually cannibalistic colonial spider

58
00:03:39.039 --> 00:03:43.960
<v Speaker 1>Cryptophora citricola, and it's about the relationship dynamics in a

59
00:03:44.000 --> 00:03:47.560
<v Speaker 1>group living spider cecies, a species that is where females

60
00:03:47.840 --> 00:03:50.680
<v Speaker 1>are prone to eat the males after sex. Researchers found

61
00:03:50.680 --> 00:03:55.280
<v Speaker 1>that the males were selective about their mates. They favored

62
00:03:55.280 --> 00:03:59.319
<v Speaker 1>the younger ones duh, and the well fed females, maybe

63
00:03:59.360 --> 00:04:03.680
<v Speaker 1>because the males hoped they wouldn't get eaten. We're in

64
00:04:03.680 --> 00:04:06.879
<v Speaker 1>the middle of austrange science. We saw that lake I

65
00:04:06.919 --> 00:04:09.319
<v Speaker 1>think they called it Ti Larry Lake here in central

66
00:04:09.319 --> 00:04:13.000
<v Speaker 1>California where outside of Fresno, there was a lake that

67
00:04:13.039 --> 00:04:17.519
<v Speaker 1>had kind of come back after this naturally occurring lake,

68
00:04:17.639 --> 00:04:21.240
<v Speaker 1>after it had been dammed and irrigated, and you know,

69
00:04:21.439 --> 00:04:24.319
<v Speaker 1>they've changed basically the water table of the central Valley

70
00:04:24.319 --> 00:04:27.800
<v Speaker 1>when agriculture came in. They're seeing something like that out

71
00:04:27.879 --> 00:04:34.439
<v Speaker 1>in the outback in Australia. Catty Tanda Lake Eyre is

72
00:04:34.639 --> 00:04:39.519
<v Speaker 1>a thirty seven hundred square mile ephemeral lake and despite

73
00:04:39.519 --> 00:04:42.319
<v Speaker 1>the fact they call it a lake, it rarely has

74
00:04:42.360 --> 00:04:44.199
<v Speaker 1>any water in it. They get about five and a

75
00:04:44.240 --> 00:04:46.879
<v Speaker 1>half inches of rain in that part of Australia every year,

76
00:04:46.920 --> 00:04:50.000
<v Speaker 1>and they said it's more like a giant saltpan in

77
00:04:50.040 --> 00:04:55.240
<v Speaker 1>the South Australian desert. In fact, like we see the

78
00:04:55.279 --> 00:05:00.000
<v Speaker 1>Great Salt Flats here in the United States. A British

79
00:05:00.040 --> 00:05:06.160
<v Speaker 1>speed record breaker in nineteen sixty four used the racetrack

80
00:05:06.480 --> 00:05:11.079
<v Speaker 1>that was this just dried saltpan to record a world

81
00:05:11.160 --> 00:05:13.480
<v Speaker 1>speed record at four hundred and three miles an hour.

82
00:05:14.439 --> 00:05:16.920
<v Speaker 1>In nineteen seventy four, the lake filled to its capacity

83
00:05:16.959 --> 00:05:20.000
<v Speaker 1>for just the third time on record. That flooding has

84
00:05:20.040 --> 00:05:22.040
<v Speaker 1>been taken as the high water mark and they haven't

85
00:05:22.079 --> 00:05:24.680
<v Speaker 1>seen it since then. But as of right now, this year,

86
00:05:25.399 --> 00:05:29.199
<v Speaker 1>tropical Cyclone Alfred dumped a bunch of rain on that

87
00:05:29.319 --> 00:05:33.560
<v Speaker 1>Queensland area, the water flowing down to this Catty Tanda

88
00:05:33.639 --> 00:05:36.360
<v Speaker 1>Lake Eyre and they said it appears to be filling

89
00:05:36.399 --> 00:05:39.240
<v Speaker 1>for just the fourth time in one hundred and sixty years.

90
00:05:39.240 --> 00:05:42.800
<v Speaker 1>A huge tourist boom as people go check that out.

91
00:05:42.959 --> 00:05:46.480
<v Speaker 1>The waterbirds that have made their way inland now are

92
00:05:46.519 --> 00:05:49.519
<v Speaker 1>also one of the reasons why so many people are

93
00:05:49.519 --> 00:05:54.439
<v Speaker 1>headed out that direction. If you're a fan of books

94
00:05:54.439 --> 00:05:57.600
<v Speaker 1>on neurology, listen. I know not everybody's going to say,

95
00:05:57.600 --> 00:06:00.519
<v Speaker 1>oh yeah, that sounds great, But Malcolm glas Well wrote

96
00:06:00.519 --> 00:06:04.319
<v Speaker 1>a book called Blink, and in it he talked about

97
00:06:04.319 --> 00:06:08.680
<v Speaker 1>the difference between our gut reactions. You know, something that

98
00:06:08.759 --> 00:06:12.160
<v Speaker 1>happens immediately and we just react to something. Sometimes it's

99
00:06:12.600 --> 00:06:16.000
<v Speaker 1>we react to the way someone looks or re react

100
00:06:16.000 --> 00:06:16.759
<v Speaker 1>to a sound.

101
00:06:17.319 --> 00:06:19.759
<v Speaker 2>We react in a way that.

102
00:06:19.839 --> 00:06:23.680
<v Speaker 1>Is faster than we can consciously even make a decision,

103
00:06:23.920 --> 00:06:25.560
<v Speaker 1>which takes a lot of brain power and a lot

104
00:06:25.600 --> 00:06:29.120
<v Speaker 1>of time. There's another book called Thinking Fast, Thinking Slow,

105
00:06:29.199 --> 00:06:33.879
<v Speaker 1>Doctor Daniel Canneman a similar book, much more detailed in

106
00:06:33.959 --> 00:06:35.920
<v Speaker 1>terms of the science behind all of that.

107
00:06:36.279 --> 00:06:38.040
<v Speaker 2>But this continues to be one of.

108
00:06:37.959 --> 00:06:41.959
<v Speaker 1>Those issues where people are fascinated by what is the

109
00:06:42.040 --> 00:06:47.680
<v Speaker 1>difference between the flash reaction to something and an actual

110
00:06:48.240 --> 00:06:52.199
<v Speaker 1>time spent by your brain making a decision about something.

111
00:06:53.160 --> 00:06:57.360
<v Speaker 1>Cognitive psychologists have talked about how to distinguish insight from

112
00:06:57.480 --> 00:06:59.040
<v Speaker 1>analytical problem solving.

113
00:06:59.079 --> 00:07:00.120
<v Speaker 2>It's a better way to put it.

114
00:07:00.480 --> 00:07:04.639
<v Speaker 1>And they say that the insight is kind of lives

115
00:07:04.680 --> 00:07:05.480
<v Speaker 1>by itself.

116
00:07:05.920 --> 00:07:07.279
<v Speaker 2>Not everyone agrees for that.

117
00:07:07.600 --> 00:07:10.639
<v Speaker 1>With that, there's a psychologist out of Temple University and

118
00:07:10.680 --> 00:07:13.240
<v Speaker 1>he says that insight might not be as different from

119
00:07:13.319 --> 00:07:16.319
<v Speaker 1>analytical thinking as it seems. And he says that insight

120
00:07:17.000 --> 00:07:20.399
<v Speaker 1>also comes from the brain gradually building on what it

121
00:07:20.439 --> 00:07:25.920
<v Speaker 1>already knows, which incorporates new information. Each failed attempt that exists,

122
00:07:26.319 --> 00:07:30.120
<v Speaker 1>your brain constantly learns and alters the way it's going

123
00:07:30.160 --> 00:07:33.680
<v Speaker 1>to react. To something based on how many times you've

124
00:07:33.720 --> 00:07:36.519
<v Speaker 1>experienced this thing. Now, that doesn't explain some of the

125
00:07:36.680 --> 00:07:40.160
<v Speaker 1>very early experiences that we have when we're kids, When

126
00:07:40.160 --> 00:07:43.560
<v Speaker 1>we're babies, there are things that we react to instinctively

127
00:07:44.079 --> 00:07:48.240
<v Speaker 1>without any previous exposure to it. I mean, think about

128
00:07:48.800 --> 00:07:52.560
<v Speaker 1>when you put a baby down in a crib and

129
00:07:52.600 --> 00:07:57.360
<v Speaker 1>their arms kind of shoot out like they're falling. Well,

130
00:07:57.399 --> 00:08:00.959
<v Speaker 1>they've never fallen before. How would they know to do that?

131
00:08:02.800 --> 00:08:03.839
<v Speaker 1>What is it about that?

132
00:08:04.480 --> 00:08:04.680
<v Speaker 2>Now?

133
00:08:04.720 --> 00:08:08.639
<v Speaker 1>This psychologist says, the main feature of insight is the

134
00:08:08.680 --> 00:08:11.759
<v Speaker 1>emotion that someone feels after they find an answer or

135
00:08:11.800 --> 00:08:15.160
<v Speaker 1>they create something that seems new. That's that aha moment

136
00:08:15.199 --> 00:08:17.959
<v Speaker 1>that I was talking about, the Eureka thing, and whatever

137
00:08:18.079 --> 00:08:22.639
<v Speaker 1>happens in your brain at that time, he says, releases

138
00:08:22.680 --> 00:08:26.360
<v Speaker 1>the right chemical or something happens in your brain neurologically

139
00:08:26.680 --> 00:08:32.360
<v Speaker 1>that reinforces whatever it was that you did that was correct,

140
00:08:33.440 --> 00:08:36.120
<v Speaker 1>That you solved a problem that you hadn't been able

141
00:08:36.120 --> 00:08:40.240
<v Speaker 1>to solve before. All that exists in this world of

142
00:08:40.720 --> 00:08:42.919
<v Speaker 1>trying to figure out how your brain works now
