00:00:03.200 --> 00:00:10.279
Caloroga Shark Media. My dog is helping me record the

2
00:00:10.320 --> 00:00:13.279
podcast today. She's very clingy. It's been reading, so we

3
00:00:13.320 --> 00:00:15.439
haven't been going for our long walk. So I think

4
00:00:15.519 --> 00:00:17.719
that's what that's about. If I get distracted, and obviously

5
00:00:17.760 --> 00:00:20.760
I'm already distracted. That's why. Hi, I hope you're enjoying

6
00:00:20.800 --> 00:00:23.719
Memorial the weekend. I'm Johnny Mack with five good news stories.

7
00:00:24.079 --> 00:00:28.000
A new AI tool can predict your biological age from

8
00:00:28.000 --> 00:00:31.320
a selfie. I'd be afraid to do this. I just

9
00:00:31.399 --> 00:00:33.640
I don't know. I'm always worried about giving my data up.

10
00:00:34.640 --> 00:00:37.479
But we could trust the scientists at Mass General Bringham

11
00:00:37.479 --> 00:00:41.200
in Boston, right. They've developed an AI two called face Age.

12
00:00:41.240 --> 00:00:44.320
It's an algorithm designed to tell patients biological age from

13
00:00:44.320 --> 00:00:48.920
a photo. Biological age is considered crucial in helping doctors

14
00:00:48.960 --> 00:00:53.399
determine the most appropriate therapy, for example, if a cancer

15
00:00:53.439 --> 00:00:57.759
patient is healthy enough to tolerate in an aggressive treatment. Researchers

16
00:00:57.840 --> 00:01:01.079
trained face Age using fifty nine thousand photographs of people

17
00:01:01.119 --> 00:01:03.840
ages sixty and over who were presumed to be healthy.

18
00:01:04.480 --> 00:01:07.280
Most of the photos were publicly available on Wikipedia and

19
00:01:07.560 --> 00:01:13.519
the IMDb Internet Movie Database. Some came from Utkface, a

20
00:01:13.640 --> 00:01:15.959
large scale data set with pictures of people from less

21
00:01:15.959 --> 00:01:18.640
than a year old to one hundred and sixteen years old.

22
00:01:19.719 --> 00:01:21.920
They then tested it on a group of sixty two

23
00:01:22.000 --> 00:01:24.920
hundred cancer patients using photos taken at the start of

24
00:01:25.079 --> 00:01:29.599
radiotherapy treatment. The algorithm determined when it came to their health.

25
00:01:29.640 --> 00:01:32.159
Cancer patients were, on average, about five years older than

26
00:01:32.159 --> 00:01:35.920
their chronological age. The tool found that the older their

27
00:01:35.920 --> 00:01:40.519
faces looked, the worst their survival outlook. Using a photo alone,

28
00:01:40.719 --> 00:01:43.480
doctors guest right sixty one percent of the time. Given

29
00:01:43.480 --> 00:01:46.200
photos and clinical information on the patients, doctors were right

30
00:01:46.200 --> 00:01:49.120
about seventy four percent of the time. Provided with face

31
00:01:49.159 --> 00:01:53.079
age and medical chart information, the doctor's accuracy reached eighty percent.

32
00:01:54.079 --> 00:01:57.280
Here's a fun one. Remember actor Wilford Brimley, who looked

33
00:01:57.359 --> 00:02:00.760
like super old even when he was young. The developers

34
00:02:00.799 --> 00:02:03.519
had face age look at photos of Paul Rudd and

35
00:02:03.560 --> 00:02:07.560
Wilford Brinley when they were each fifty. The algorithm thought

36
00:02:07.599 --> 00:02:12.680
Paul Rudd was forty three for Wilford Brimley sixty nine.

37
00:02:13.240 --> 00:02:15.800
Brimpley did live to be eighty five, though he looked

38
00:02:15.840 --> 00:02:19.240
sixty for about forty years. Hey good news for Harvard

39
00:02:19.319 --> 00:02:22.639
Law School, they had a copy of the Magna Carta.

40
00:02:22.680 --> 00:02:25.639
It turned out to be a real one. That's right.

41
00:02:25.680 --> 00:02:29.520
A manuscript once considered an unofficial copy of the Magna

42
00:02:29.639 --> 00:02:32.719
Carta is now believed to be a genuine version and quote,

43
00:02:32.719 --> 00:02:36.840
one of the world's most valuable documents. Harvard acquired this

44
00:02:36.879 --> 00:02:40.080
thing in nineteen forty six for twenty seven dollars and

45
00:02:40.159 --> 00:02:44.039
fifty cents. It was tucked away in the library. Everyone

46
00:02:44.120 --> 00:02:48.280
was like, yeah, it's copy whatever. Professor David Carpenter from

47
00:02:48.360 --> 00:02:52.319
King's College, London began analyzing it after seeing digitized images

48
00:02:52.360 --> 00:02:54.960
of it on the website. He explains it is the

49
00:02:55.039 --> 00:02:58.759
last Magna Carta and it deserves celebration, not some mere copies,

50
00:02:58.800 --> 00:03:01.080
stained and faded, but as an original of one of

51
00:03:01.120 --> 00:03:05.560
the most significant documents in world constitutional history, a cornerstone

52
00:03:05.560 --> 00:03:09.599
of freedom's past, present, and yet to be one. According

53
00:03:09.639 --> 00:03:14.319
to Harvard Documents, HLSMS one seven to two was acquired

54
00:03:14.319 --> 00:03:18.319
in nineteen forty six was described in an auction catalog

55
00:03:18.360 --> 00:03:20.719
as a copy made in thirteen twenty seven, somewhat rubbed

56
00:03:20.759 --> 00:03:25.199
and damn stained. How much is it worth today? Well,

57
00:03:25.319 --> 00:03:28.080
A twelve ninety seven Magna Carta sold at auction in

58
00:03:28.080 --> 00:03:30.280
New York in two thousand and seven for twenty one

59
00:03:30.319 --> 00:03:34.360
million dollars. Comedian Sebastian Fowler jumped on a bike. He

60
00:03:34.439 --> 00:03:36.919
covered three thousand, three hundred and thirty three miles across

61
00:03:36.919 --> 00:03:39.919
eleven states in eighty days. He was on his twenty

62
00:03:39.960 --> 00:03:43.280
inch BMX bike loaded with twenty seven kilograms of gear.

63
00:03:44.360 --> 00:03:47.000
He did this as part of a cross country comedy tour,

64
00:03:47.159 --> 00:03:50.199
and while doing it, raised money for kids to get

65
00:03:50.240 --> 00:03:53.719
BMX bikes. He explained, you might laugh at this, but

66
00:03:53.719 --> 00:03:55.960
when I thought about riding across America, I figured it

67
00:03:56.000 --> 00:03:58.479
was about three thousand miles. I rode my bike downtown

68
00:03:58.479 --> 00:04:00.560
from my house in Ocean Beach to downtown on San Diego.

69
00:04:00.639 --> 00:04:01.960
That was about ten miles, and I thought, if I

70
00:04:02.039 --> 00:04:04.479
do that three hundred times, that's the whole trip, and

71
00:04:04.479 --> 00:04:07.400
that's the mentality I went with. He had it out

72
00:04:07.400 --> 00:04:11.800
on February twenty fifth, departing Ocean Beach on his Sunday

73
00:04:11.840 --> 00:04:16.279
Odyssey BMX bike wearing vans slip on Damn Daniel skate

74
00:04:16.439 --> 00:04:20.279
pros and started pedaling east a long Interstate eight. That

75
00:04:20.319 --> 00:04:23.079
sounds pretty scary to have a bike on an interstate highway.

76
00:04:23.120 --> 00:04:26.120
I've been on that road. Fowler says, no one's ever

77
00:04:26.199 --> 00:04:28.160
done this trip on a BMX bike. No one's ever

78
00:04:28.199 --> 00:04:30.079
gone coast to coast on a BMX bike. And there's

79
00:04:30.120 --> 00:04:32.839
a good reason for that, because it's a terrible idea

80
00:04:32.959 --> 00:04:37.279
and really hard. Well eighty days later, he pedaled into

81
00:04:37.279 --> 00:04:40.240
New York City on May fifteenth. He did have a

82
00:04:40.279 --> 00:04:44.639
scary story. One night he was out there, four pairs

83
00:04:44.639 --> 00:04:46.639
of green eyes tracked him from the roadside. They were

84
00:04:46.800 --> 00:04:49.319
mountain lions. He said, I pulled my knife out and

85
00:04:49.360 --> 00:04:52.360
just started screaming like a madman. I unlocked this primal

86
00:04:52.439 --> 00:04:54.279
sense of myself that I didn't know existed. But I

87
00:04:54.319 --> 00:04:56.600
was also terrified because they knew once the bike light

88
00:04:56.639 --> 00:04:58.879
and my headlamp died. Their eyes are a lot better

89
00:04:58.920 --> 00:05:02.199
than mine. So I called the c If you would

notes for that. Good news. If you want to know

103
00:05:36.399 --> 00:05:40.360
what time it is, a new atomic clock known as

104
00:05:40.399 --> 00:05:44.399
the NISTF four at the Boulder, Colorado campus of the

105
00:05:44.519 --> 00:05:50.040
National Institute of Standards and Technology is like super accurate.

106
00:05:50.160 --> 00:05:52.959
The clock works on caesium atoms, which, as you know,

107
00:05:53.160 --> 00:05:55.800
oscillate between quantum states at a frequency of over nine

108
00:05:55.839 --> 00:06:00.160
billion times per second. NISTF four uses lasers to who

109
00:06:00.639 --> 00:06:03.839
ball of caesium atoms to near absolute zero, then measures

110
00:06:03.839 --> 00:06:05.600
of the frequency of the atoms as they passed through

111
00:06:05.600 --> 00:06:09.160
the microwave chamber. As they rise and fall like water

112
00:06:09.160 --> 00:06:12.360
in a fountain. The atoms oscillate ticking more than nine

113
00:06:12.480 --> 00:06:16.480
billion times per second. How accurate is it? Scientists say

114
00:06:16.480 --> 00:06:19.439
if this clock started running one hundred million years ago,

115
00:06:20.160 --> 00:06:23.199
it would be off by less than a second. And

116
00:06:23.399 --> 00:06:26.120
we've got another loose kangaroo. I don't know what's going

117
00:06:26.120 --> 00:06:29.199
out there in America? If you've got a kangaro as

118
00:06:29.199 --> 00:06:32.959
a pet, they apparently escape a lot. Irwin, the pet kangaroo,

119
00:06:33.480 --> 00:06:37.519
got loose last fall in Colorado. He was young at

120
00:06:37.519 --> 00:06:39.879
the time, and he hopped into a bag similar to

121
00:06:39.959 --> 00:06:43.319
a mother kangaroo's pouch. Last week or when got out again,

122
00:06:43.480 --> 00:06:46.160
he's got bigger. The cop said that bag technique wasn't

123
00:06:46.199 --> 00:06:49.759
going to work. How did they catch the kangaroo? Well,

124
00:06:49.839 --> 00:06:53.279
Officer Sheen is described as a farm boy with animal

125
00:06:53.319 --> 00:06:57.480
handling experience, cornered Irwin the kangaroo near a house, snuck

126
00:06:57.560 --> 00:06:59.800
up close to him and grabbed him. He carried the

127
00:06:59.800 --> 00:07:02.199
cane garoto a police truck's back seat and shut the door.

128
00:07:03.279 --> 00:07:07.040
Erwin was taken home to his family. They're not sure

129
00:07:07.079 --> 00:07:09.560
how Irwin got out, but the kangaroo's now two, and

130
00:07:09.720 --> 00:07:12.720
kangaroo experts tell us by h four or five, kangaroos

131
00:07:12.720 --> 00:07:14.720
can grow taller than most men, and we'll weigh two

132
00:07:14.759 --> 00:07:17.360
hundred pounds. They can hop much faster than a person runs,

133
00:07:17.639 --> 00:07:20.480
and they have a powerful kick. So keep an eye

134
00:07:20.480 --> 00:07:22.639
on your kangaroos. And those are your five good news

135
00:07:22.680 --> 00:07:25.079
noies for today, all right? I have a good one,
