We told you on January 28th how the collapse of a damn at an iron mined sent a flood of mining, debris and mud into the city of Bruma Gino. 3

The number of people who died from the incident has risen to 150 and Brazil's government says at least 182 others are still missing. 4

Rescue officials do not think they're gonna find any more survivors, according to the British Broadcasting Corporation. 5

It also reports that valet, the company that owns the mine, says it followed recommended safety procedures. 6

But this is the second mine owned by Valley where a dam has collapsed. 7

The other incident happened in the same region in 2015 killing 19 people and polluting the environment. 8

And as the Reuters news organization reports, a Brazilian state official recently blamed the same problem for both disasters. 9

Parts of the dam, which was made of dried mud and sand, turned into a liquid, causing the structure to fail. 10

In addition to the lives lost, the collapse contaminated a river downstream with mining, debris, waste and toxins, and observers say the resulting pollution from that could indirectly impact millions. 11

There's a growing challenge facing China, specifically the future of its economy, and it's a consequence of the communist government's controversial one child policy. 12

In the late 19 seventies, the world's most populated country wanted to slow down the growth of that population, so it instituted a policy in 1980 that limited families toe one child. 13

In some cases, it forced couples to stop having Children. 14

The program ended in 2016. 15

Chinese families are now allowed to have two Children, but the results of the limit mean fewer Children are alive to support the country's aging population. 16

This is a brutal trudge for a healthy person. 17

But for 68 year old chain tie shout, stricken with emphysema and cancer, it's near torture. 18

He keeps warm by burning firewood. 19

It's cheaper than cold. 20

What can I say? 21

He says. 22

Life's all right. 23

There's no other way. 24

That steely stoicism is common in China's rural villages, where life has only gotten tougher. 25

Young people have been largely swept away by the relentless current of China's urban migration. 26

Cheese Children left for work years ago. 27

He and his wife, son should wrong carry on alone. 28

It's difficult for our Children to care for us, she says. 29

We don't want to become a burden. 30

150 miles away in Beijing, it's a burden that 32 year old fun monk rose well. 31

She and her husband financially support both their parents, the four grand parents of their five year old dog. 32

She she likes to ski and she enjoys diving, Fund says. 33

If those air her interest, we have to support her. 34

That all costs money. 35

The village couple and their city counterpart are a microcosm of China's aging problem. 36

Simply put, there are a lot more older people in China than younger ones, and an aging population, along with greater life expectancy, can have drastic consequences. 37

Less working age people might limit the government's ability to pay for the benefits needed by its aging population. 38

National economic priorities will shift more towards health care and pension obligations, and it might also hurt consumer spending with the combined effect of slowing China's economic growth potential way down. 39

The obvious solution here is to have more babies, but that's not happening. 40

There were two million fewer births in 2018 and most studies agree that China's population will soon begin to shrink. 41

The government knows this, and in 2016 change the notorious one child policy. 42

Couples are now allowed to have two babies per family and their speculation. 43

The Communist Party could erase any restrictions as soon as this year. 44

But for families like Fond Munnings, that doesn't matter. 45

You know, for me, she says, one baby is enough. 46

One baby is what I can afford in terms of both energy and money. 47

Not wanting more kids is a nationwide trend that's unlikely to change with higher costs and more opportunities for women as two reasons. 48

Back in the village, Jean Tie Shao and his wife survive on about $1500 per year, selling corn at some point, though hauling 50 kilos of wood twice a day will be too much and his meager income not enough, he'll need help just like all of China's older citizens. 49

Whether there will be enough young people to support them is one of Chinese societies, great questions. 50

Matt Rivers, CNN, Beijing Niccolo Ahmadi, like Antonio Strata, very became famous for his work with what? 51

Paintings, fountains, instruments for bridges. 52

Some of the greatest violins ever made are associated with the ahmadi and strata, very families. 53

Some of their violins are said to be acoustically. 54

It's not known what makes them that way, Encyclopedia Britannica says. 55

Some believe it's in the instruments, mysterious varnish. 56

Others say it's a combination of that, plus the thickness and condition of the wood. 57

There's a project going on that uses modern technology to carefully document their historic tones. 58

Few things compared to the sound of a virtuoso playing. 59

But this is no ordinary instrument. 60

It's an Amati viola from the 17th century, and it's being played here in Cremona, where music making is an art form. 61

Thes instruments are displayed in the town's renowned violin museum, Renaissance and Baroque masterpieces made by legendary artisans like Stradivari and Amati, who created many of the first violins, viola and shallows as we know them Today. 62

No one makes string instruments like this anymore, which were created to delight the royal courts of Europe and the unique sound they create. 63

Cappie replicated either maestro Fausto Cacciatore is in charge of taking these precious instruments out of their museum cases and down to the auditorium where their sound can be recorded. 64

My dream is that these instruments that we're conserving will be played in two or 300 years time and that the sound is just like we hear today, he says. 65

To tech companies have teamed up to immortalize the notes of these centuries old instruments into a sound bank to do just that record everything you can perform on the violin, but not as part of the musical performance, but basically bit by bit one by one. 66

So we're recording long notes, short notes, just broken down into very tiny pieces and elements off the performance. 67

Once the recordings were finished, software developers will be able to use the notes and tones for their own compositions, but it takes complete silence. 68

In order to carry out these reportings, the town has had to cooperate. 69

They've closed the street with cobblestones to traffic in order to try to limit the vibrations and reverberations inside the recording studio, the project creators believe the sacrifices will pay off. 70

It would be something that will have digital closer to make music, and it will be a very practical tool. 71

But it will never be like having a live musician. 72

Barbie for CNN Ramona Family Reunion gets a 10 out of 10 today, but it's a family that's a little hotter than you're used to. 73

Literally a little honor. 74

It was found earlier this week by a commercial fisherman. 75

After the pub became separated from its mother, officials recorded the pups, cries and then played them over a speaker so the mother could hear. 76

After they located her, they tossed the pup in, and after a few moments, she pops up to get her baby. 77

Her baby is like no water, so you can't say she forgot her, though a fisherman had caught her, Mama Otter had begot her, and it's clear that she had sought her so that when the man had brought her, it turned any other day to a special modern day. 78

So if you catch one, don't play possum, find the mom and then just toss him. 79

It's a sample. 80

An example of how Fridays are awesome.
