Welcome to your midweek edition of CNN.
10.
My name is Carla Zeus.
It's great to see you.
We've done some reporting lately on the destructive wildfires in California, the state still in the midst of it's fire season, when blazes arm or likely to flare up.
But the major wildfires we've told you about have been contained for the most part.
Now, though, some people in Southern California are in danger of another potential disaster.
Flooding.
The U.
S.
Army Corps of Engineers, which operates and maintains about 700 dams in America, recently issued a new warning about the Mojave River dam.
It's located at the northern side of the San Bernadino Mountains, and last year the core ran a risk assessment of it and concluded that if water flows over the top of the dam during an extreme flood event, the dam could fail to be clear.
The core saysthe kind of flooding that could cause that is unlikely and it's never happened before.
But it's drawing attention to the issue because the area expects more rain this winter, and if the dam were to fail, flooding could affect more than 315,000 people who live in nearby communities about 70 miles northeast of Los Angeles.
The Mojave River dam was built in 1971 that makes it younger than most of the dams across the U.
S.
There are more than 90,000 of them, and most are more than 50 years old.
They helped provide irrigation and hydropower and protect communities from flooding.
But many across the country are under review, and the importance of assessing them became clear in 2017 when the Oroville Dam in Northern California was damaged after heavy rainfall that led to the evacuation of 180,000 people.
Before water levels at the dam dropped four years ago, the Army Corps of Engineers estimated it would mean $24 billion to fix all the dams that needed repairs.
Which of these animals hibernate in winter?
Tree, squirrel, mosquito, monarch, butterfly or silver?
This mosquitoes are the only animals on this list that enter Dia pause, a hibernation like period of shutting down for the cold winter months.
So that explains why the pesky pests always come back in the summer.
And when they do, why do they always seem to bite some people more often than others.
Scientists say there are a number of things mosquitoes are attracted to.
Strongly scented soaps are believed to get their attention, along with certain deodorant, CE and perfume.
The increased carbon dioxide we give off when we're exercising can create a buzz among the insects as well as our sweat.
As faras clothing goes, researchers are divided over whether it's bright or dark clothes that make us easier for mosquitoes to spot.
But a recent study has found that different types of body odor could make some people more prone to mosquito bites than others.
Is there anything that can be done about that maybe one day, if a drug is designed that can change those odors?
Could that have side effects of its own?
Yes.
But because of the diseases they carry, mosquitoes are responsible for Maur human deaths than any other animal.
There's a lot of international interest in keeping them away.
It's not all in your head.
Some people really are more attractive to mosquitoes than others.
Research has determined that it has to do with how each of us smells, which is individual to everyone and partly determined by our DNA.
Fraternal twins are much less similar to each other than identical twins are in terms of DNA and odor.
So experts in London conducted a study between fraternal twins and identical twins to see if there was a difference between the two.
When they exposed the twins to mosquitoes, they found that identical twins were bitten in similar amounts.
But fraternal twins were bitten in differing amounts, meaning that mosquitoes really do bite some individuals more than others.
And that's at least partially because of body odor.
Scientists already have a sense of which compounds in human odors attract mosquitoes.
They're hoping to develop a drug that changes human body odors to make them less attractive to mosquitoes.
That could have major public health benefits, especially in areas where mosquitoes transmit diseases like malaria, dengue fever and West Nile virus.
We are about eight and 1/2 months away from the next Olympics.
The 2020 games will be held in Tokyo, Japan.
They'll run from late July through early August and about a month after the Olympics begin.
The Paralympic Games get started running from late August through early September.
The Tokyo organizing committee says they will be the biggest and most exciting Paralympic Games ever held.
And the young man who hopes to be there is busy training in the pool when he's not studying acting or modeling.
Wait, do you know Wait, Don't make me get up to fill the shoes.
D'oh!
Media like this is a photo.
You should come too.
Supposed t o T o T o u says fusion that.
Did he Yes.
Francaise contre Olivia, You threw away a cyclo.
Contributed position.
So, Phil, don't say very much.
Uncle Holder John Nash, Motome.
You want to get you to look in any deal on Sean O'Malley?
You could see your question.
She said the field issues objective.
Ah Kuk town Martin.
Scary people took you on the way, but I don't see how I felt sexy pictures telling CNN Solo seven years to get so bad back in college, I want to talk my way out of a parking ticket.
I was leaving for the summer and told the attendant that if she let me go, she wouldn't have to ticket me for at least three months.
Well, that worked for me.
What's working for?
Some students at the University of Alaska is paying their parking tickets with peanut butter and jelly.
What?
It's a program called Food for fines.
It's part of an annual food drive for hungry students for people with unpaid fines.
The more food they donate, the less they have to pay for one week.
The program includes PB and J.
For the next, it's canned soup might make those who chose to pay in cash a little jelly, but it's easy to see sandal which option to choose here.
Sure, you can reach in your wallet for 50 Smucker's where you can Skippy on over to the grocery store, buy some food in a jiffy and things Peter Pan out for the better, Just in time for CNN.
