I'm Carl Azusa, CNN Center.

The border between the United States and Mexico has been getting a lot of attention lately, and U.

S President Donald Trump is planning to visit the area again on Thursday.

He wants Congress to approve $5.6 billion in funding for a wall along the US Mexico border.

The House of Representatives approved that money in December.

The Senate did not, and because Congress and the president couldn't agree on funding for the wall is part of a bigger funding package for the federal government.

Ah, partial government shutdown began on December 20 2nd we explain that explored this issue last Friday.

You can find our January 4th show in the archives section at CNN Tenn dot com.

By partial shutdown, we mean that about 25% of the government is closed.

It includes 800,000 federal employees.

About half of them won't be paid until the government reopens.

The other half are forced to take time off without pay.

Republicans and Democrats air pretty well dug in on their positions concerning the wall.

Most Republicans want the funding approved so it could be built.

Most Democrats want the funding denied so it can't be built.

The president and lawmakers have had several meetings to discuss the issue, but as of Monday night, there'd been no breakthrough.

So without a government funding plan in place, the shutdown continues.

There have been more than 20 partial shutdown since 1976.

The longest lasted 21 days, from 1995 to 1996.

In the late 18 hundreds, Swiss chemist Friedrich Mischer became the first scientists to identify what magnetism DNA thermodynamics were X rays.

Decades before Watson and Crick were at work, Mischer was the first to identify what would become known as deoxyribonucleic acid, or DNA.

Decades DNA has been used in criminal justice.

To identify suspects were clear.

People who've been falsely accused now a type of technology called D N a Fi.

No typing could take crime scene analysis to another level in D N A profiling, which investigators have used for years, they try to match DNA from a crime scene to records they already have in their system.

With the new technology, genetic information doesn't need to be matched or compared.

It uses the DEA Onyx Stone to predict what someone could look like.

The process isn't cheap, and there are privacy concerns about it.

If you're listed in ancestry dot com, for instance, your relationship to a suspect could be discovered.

But this is changing the way some investigations air carried out.

The technology is called D N a fi.

No typing developed by Para Bon Nana Labs from just a small sample of DNA, they can create a composite image of what someone could look like.

What kind of impact think that this technology will have on forensics?

Long term.

Here we have another avenue we can explore if we run into dead ends along the way, we're essentially bringing in entirely new ways to analyze forensic DNA.

Traditional forensic DNA analysis looks just at Cannes.

This DNA from a crime scene be matched to a suspect we've already identified or to a database, but if you don't find a match, it couldn't tell you anything else.

We can generate leads just from the DNA.

That's at that crime scene para bombs started to offer.

Forensic service is to law enforcement in 2015.

Since then, they've assisted in over 40 cases.

A lot of the cases we work.

It turns out that they had some information that was leaving them in a particular direction, and our information completely redirects.

You know, you're not looking for a person of that description.

You're looking for percent this very different description.

And once they pivot and start going down that road, they could find that person our D, and carries a specific instruction set for an individual's physical characteristics.

With only a small sample, Para Bon can pull from tens of thousands of genetic variants to predict what a person looks like.

So basically, we're predicting where the face falls on different facial dimensions in what we call face space.

And so this all just comes out of some math that we do on face data.

And as the numbers change, it's showing different possible faces.

So there's a wide variety of possible faces that could be predicted.

That looks like you, that is, this may not be my driver's license image, but if I were pretty close exactly, yeah, the service costs about $3000 but the results could mean authorities been less time and manpower to solve a case.

The composites do have limitations, though.

For instance, DNA doesn't reveal a person's age.

So to compensate, Paragon estimates what the person would look like a present day based on how long ago the crime was committed.

And it is simply a guide, the FINA type alone cannot lead to a conviction.

It's a kind of stuff from a sci fi movie, you know what I mean?

The FINA typing is definitely very SciFi.

Are there any like privacy concerns, or what are the moral implications of all of this?

Well, with Dina, Fina typing were only predicting things that the person makes public every day.

When they go outside, you know their eye color, their hair color.

We're not looking at any medical information or anything like that.

And then with genetic genealogy, all the research that we d'oh is public information.

Along with Fino typing, genetic genealogy is being used as another tool para bon and law enforcement agencies are using to catch criminals and close cold cases.

By searching a public database of D n, a genealogist can work backwards and a family tree, narrowing the search for a suspect going forward, the number of cold cases will decrease, and also active cases can potentially be solved more quickly.

You came for.

They become cold cases.

Actually, cases won't have to go cold on.

11 year old named Liam Hannan is making headlines in Cambridge, Massachusetts.

A couple years ago, he decided that instead of summer camp he'd find another way to stay busy.

That led to his idea to donate lunches to the homeless in his community, and that led to collecting school supplies and toys for homeless Children.

And all of this is why Liam is one of CNN's young wonders.

I think about how tough it is for someone to be homeless.

Everyone should have a place to live, hoping people is important to me because people just need a little kindness in my life.

My name is Lamb Hannan, the mission of Liam's lunches of love to give food to people experiencing homelessness.

Usually when people think about Cambridge, they think of Harvard and M I T.

And expensive real estate.

But what they don't think about is that we have over 500 homeless people on our streets every night.

I was really scared At first I thought that people might be mean to me.

But once I gave the first lunch Oh, I realized that mostly everyone was really nice When I gave someone a lunch, their face lit up.

From there, things just grow.

The next week we give 50 lunches, and then we did 60 and 70 and it was very quick that people were into helping.

Since July 2017 we've made 2000 or more lunches.

You guys, I just wanted to say hi.

And that on Sunday I am passing at lunch is so if you guys want to come and help, that would be awesome.

So see you guys later.

Bye.

Who wants to make sandwiches?

I'm doing okay.

A lot of my friends have actually come and help.

Do you want a core apples and then put them into sandwich bags, decorating the bags and making villages?

I know that they're gonna go to someone that needs it.

Who could make more slices of their 1st 321 way did a turkey drive together?

He's really expanded from just the lunches and doing so much more.

Liam is gonna change the world.

I'm definitely proud that I've come all this way to make that many lunches.

You just have to start small, get home from friends and do something that you love.

Freshly baked bread in vending machine to things that don't sound like they go together, but they could with the bread.

But it's a vending machine that can do all the steps to turn dry ingredients into fresh bread.

In about an hour and 1/2.

It's Maker's estimate that each breadbox would retail it around $100,000.

It be leased to grocery stores, and the company says the machine would increase their profits and help.

The environment could lead the confusion.

When you brought it home, though.

Hey, is that store bought?

Yeah, it's bread, but I know it's bread bought.

Is it from the store?

Yeah, it's store bought bread, baht.

But how is it Brad bought if it's store bought at the store I bought?

Brad bought.

What do you mean that it's bread bought?

Look, just try it.

It saved me some bread.

I mean it.

Save me some dough.
