What's officially the first day of spring in the Northern Hemisphere? 3

Thank you. 4

Set aside 10 minutes to watch CNN. 5

10. 6

I'm Carla Zeus at the CNN Center in the U. 7

S. 8

Midwest. 9

The north central part of they're states of emergency in Nebraska, Iowa and Wisconsin. 10

Lots of rain plus melting snow, plus a late winter snowstorm brought by a bomb cyclone have left many places underwater. 11

Part of the problem was that the ground was still frozen when the rain came and it wasn't able to absorb the water. 12

So it found its way to rivers and streams and caused them to burst their banks and spread water all over. 13

On Tuesday morning, the National Weather Service said more than eight million people were under flood warnings. 14

Nebraska was hit particularly hard. 15

It's governor said the flooding was the most wide bread disaster Nebraska had ever faced. 16

U. 17

S vice president Mike Pence traveled there yesterday to survey the damage. 18

Nebraska's governor is hoping the federal government will allow public funding to be used to help those affected. 19

In 17 places across the state, flood records were broken, and in Iowa, 41 of the state's 99 counties have been declared disaster areas. 20

In addition to at least four lives that were lost in Nebraska and Iowa, farmers have lost grain and livestock fields or underwater private water supplies or threatened south of Nebraska and Iowa. 21

The Missouri and Mississippi rivers, which are already at minor or moderate flood stage, are expected to rise higher in the next few days. 22

So states like Kansas, Missouri and Illinois could Seymour flooding in the days ahead. 23

In some places farther north, the water has begun to recede, and others, the threat remains. 24

This is Winslow, Nebraska, for several days. 25

The people who live here in the small town of less than 200 people can't even get him here to see what it looks like. 26

Now they're able to clear away some of the debris on the roadway. 27

But as you can see, look at the speed limit sign. 28

You can see how high the water still is, How high up it is on these houses. 29

In every one of the houses in this town are surrounded by water. 30

You could see so many things have been pushed away toys, picnic benches and even stares moved far away from the homes that they used to stand next to. 31

Right now, while they're able to get closer, they still cannot get into their homes. 32

And they don't know when they'll be able to, because there's still so much water in here. 33

And this is just one system where the water is starting to receive when in others it's still crusting. 34

So this is just a microcosm. 35

Ah, small picture of what is happening throughout Nebraska with these massive, devastating floods. 36

And I talked to one couple that has lived here for several decades over 30 years and asked what they were going to rebuild. 37

And he said, We have nowhere else to go. 38

This is where we belong. 39

Entire apartment started shaking, and there's a huge new. 40

I was just terrified at no idea what's happening, huh? 41

So if a meteor explodes in the atmosphere and no one's around here, it doesn't make a sound. 42

NASA says it did. 43

The fireball that blew up 16 miles over the Earth's surface in December was the second most powerful one to enter our atmosphere in 30 years, according to the space agency. 44

So why wasn't this reported in December because scientists just noticed it. 45

It was originally detected by military satellites and reported to NASA afterward. 46

Why didn't pictures and video go viral on social media like those of other fireballs do? 47

Because it happened over the Bering Sea in a pretty remote part of the world? 48

And relatively few people noticed what exactly caused a blast that powerful a meteor that scientists say was probably a few meters across. 49

That's all it takes to release 100 and 73 killer tons of energy and for reference, one kill Aton is equivalent to £1000 of TNT. 50

Should you be worried about another one? 51

Scientists say no. 52

Most fireball events air smaller. 53

There have already been five noteworthy explosions in 2019 10 seconds. 54

Where would you be most likely to find mycelium, a massive filaments in granite, on a CT scanner on body armor? 55

Or in a fun guy? 56

Vegetative, part of a fungus is called mycelium. 57

A growing number of artists, furniture makers and even clothiers are using mushrooms to make stuff, and a big provider of the material for this is a New York based company called Eco Votive. 58

It's a bio materials organization that's received millions of dollars in grant money from the U. 59

S. 60

Government. 61

In addition to private funds from private investors, it's worked on everything from building materials to packaging, all based on using part of the mushroom. 62

When it comes to shipping materials, it's not always the perfect substitute for Styrofoam or other plastics cooperatives original. 63

My cell ium foam could beam or expensive to use than traditional materials for lightweight packages. 64

But its makers say it is better for the environment, and it's changing the way people think about mushrooms. 65

Since the 19 fifties, humans have produced over nine billion tons of plastic, most of that is ending up in landfills and could take centuries to decompose. 66

A miracle Material found in nature could be the key to reducing plastic waste. 67

It's called Mycelium, and it comes from mushrooms. 68

Miss Ilium is like the root structure of a mushroom. 69

You're used to seeing a much from above ground. 70

Miss Ilium is like the roots beneath it, but no one that ever tried to use them to make materials. 71

Evan Bayer is the CEO of Excavated, a company that has developed a way to grow my psyllium into specific shapes and sizes. 72

They start by taking organic plant ways and mixing it with my silly themselves, which act as a sort of natural glue. 73

The Miss Cillian grows through and around those particles, and it binds them together and you've got a grown product. 74

Excavators. 75

My psyllium products provide a natural alternative to packaging materials made out of plastic and styrofoam, but at the end of its useful life, you can actually break it up and you could put in your own garden. 76

So it's It's a nutrient, not a pollute. 77

Excavated wants to take my psyllium to the next level. 78

Our current technical focus is developing the next generation of Sicilian materials from cell scaffolding, leather like materials, even meet replacements, a k a. 79

My psyllium bacon, which is still in its testing phases. 80

The company thinks by Salim could also play a major role in construction and even in regenerative medicine. 81

It really has boundless possibilities, and it comes from its ability to move from the micro scale to the macro on Astro Lab, found off the coast of Oman in the Middle East, has just been awarded the title of world's oldest by Guinness World records. 82

An Astro Labor is an instrument that was used for centuries to mark the positions of the sun and stars. 83

They were first used by astronomers hundreds of years. 84

B C and sailors use them in the Middle Ages until Astral Abe's were replaced by Sexton's. 85

Today, just over 100 Mariners Astral Abe's air known to exist in the world. 86

But add this one to the tally. 87

About five years ago, divers found in a shipwreck site near Oman. 88

Researchers believe it was made between 14 96 and 15 01 and it's thought to have been used by Portuguese navigator Vasco de Gama, who was the first European. 89

The sale from Europe to India. 90

The Astro lab had to be kept in a freshwater bath for two years to get all the salt off. 91

A symbol of Portugal's royal coat of arms helped scientists identify it. 92

They hope its discovery will help them understand more about how ships navigated in the 14th and 15th centuries. 93

Hello, Ski. 94

Using helicopters to reach remote places to ski has been around for decades, far as we know, Zeppelin skiing, using an airship to get out in the back country EAS pretty new. 95

These three Austrian skiers worked on the idea for almost two years before it became reality. 96

In February, they needed cold temperatures, clear skies and no wind. 97

They also needed to descend by rope to the Alpine summit they intended to ski. 98

Was it worth it? 99

You'd better do original. 100

Believe it. 101

Of course, there were a few bumps in the road. 102

Their path to success wasn't always Zeppelin e er, and it took a while before everything was an airship shape. 103

Big dreams often have steep slopes and obstacles to traverse. 104

But once there's got off the ground despite the ropes that repelled them, they all clearly had a descent. 105

Don Carlos and we'll see you later on CNN.
