 Welcome to Wednesday. This is CNN Student News. We're going to get things started today with different forms of extreme wheather. First up, fire. This one in California has burn more than 30,000 acres, but fire fighters have around 60 percent contained, and some people who were told to leave their homes because of the fire had been allowed to go back.

Different story with this blaze in the mountains of Mexico, it has only burn around 8,500 acres, so significantly less than California. But it was also less than 10 percent contained yesterday.
From fire now to water, the Mississippi and Missouri River have topped their banks in some places, flooding areas along their path. Waters broken through two levees, barriers that is designed to hold back flood waters.
This is CNN Martin Savidge. Last August, he was standing1 in the basin of the Mississipi River near Memphis Tennessee. It had dryed up then, because of severe drought. Now, Martin Savidge again as water from the Mississipi rushes across the road and over his feet. The river has gone out 45 feet in the last 5 months.
101 high school students and 8 chaperons were kicked off a  flight from New York to Atlanta. That much, both sides can't  agree on, but the accounts of what let this happen are where we are getting some very different stories.
It happened on an early morning air trend flight on Monday, before the plane left ground. The Airline says the students wouldn't stay seated, some were using their mobile devices after being asked not to, and when the group wouldn't follow the requests of the flight crew including the captain. They were asked to leave the plane.
One of the chaperons says everyone in the group listened when they were told to sit down and turn off their phones, although some of the students might have to be told twice. Another chaperon said none of the students were specially2 loud or disruptive. The opinion of the students and the chaperons is that the flight crew over reacted. The airline's view is that the group was violating safety regulations.
Today's first Shout out goes out Mrs. Silvestri's current events class at West Warwick High School in West Warwick Road Island. The dinosaur3 triceratops lived during what geologic4 period?  Was the Cretaceous period, Paleozoic era, Jurassic period or Pleistocene epoch5? You've got 3 seconds, go!
Triceratops are classifed under the Cretaceous period, around 65 to 145 million years ago. That's your answer and that's your Shout out.
Triceratops are believe to have been one of the last flightless dinosaurs6. When you pictured one, you probably think of the three horns on its head or that big bone on the back of the skull7.
A rancher in Wyoming came aross a lot more than just that one bone recently. The scientists whom he told about it say it's one of the complete skeletons ever found of triceratops. And it's not just one, three of them were found together in one spot. Thar's interesting, too. One researcher says before now, there wasn't much evidence that the triceratops moved in groups. These dinosaurs were plant eaters, but they were targeted by hungry predators8 like tyrannosaurs and scientists say the bones indicate that the t-rex is probably how these three triceratops died.
De extinctioning might not sound scientific but that's those who want to do it, call it. It's a movement to try to bring back species that humans help make extict like the dodo bird or Tasmanian tiger. It's not known whether people had anything to do with the demise9 of the wooly10 mammoth11. But a recent discovery in Siberia has brought more weight to debate over de extinctioning.
The mammoth is so well preserved by ice that some scientists think they might be able to clone it. According to a professor at University of California, that's one possible way to de extinct the animal: cloning takes the DNA12 from the extincted animal cells creates an embryo13, and has the similar living animal carry and give birth to it. In case of mammoth, they probably use elephant.
Scientists tried this with an extincted type of ibex, a while back, it died just after it was borned. But some are awfully14 attempted to try again with mammoths. It kind of brings back questions from Jurassic Park though. Even if the scientists could clone the extinct animal, it's not clear ethically15 if they should.
--As a scientist, I'm conflicted about whether we should or should not bring extinct species back to life. But it's hard to stop scientists and to start progress, stop progress, and particularly when there is something that's cool and captivating of people's imagination as the opportunity to bring something back to life.
Critics argue that the extinct species were meant to be that way for a reason, and some biologists and wild life experts fear that if we the ability to clone whatever goes extinct, we won't try very hard to preserve the endangered species and threatened habitats we currently have.
