CARL AZUZ, CNN ANCHOR: Divisions have deepened in some parts of Ukraine, and in today`s show we are starting with the unrest that`s causing it. This is CNN STUDENT NEWS. We`ve told you how Ukraine is the nation divided. Some people there want to be more closely associated with Europe, to Ukraine`s west. Others want closer ties with Russia, to Ukraine`s east. Protests by the pro-Europe side earlier this year led to the removal of Ukraine`s former president. But in several cities, there are no protests by the pro-Russia side. And yesterday, some demonstrators took over Ukrainian government buildings, raised Russian flags and said they wanted a new government. Ukraine`s current leaders blame Russia for this. They say Russia is stirring up these protests so it can annex more areas of Ukraine, like it did in a pro-Russian region of Crimea last month. Russia says Ukraine`s government is acting irresponsibly, that it should listen to its people and quit blaming Russia for its problems.

A royal visit to the Southern Hemisphere. Britain`s Duke and Duchess of Cambridge, more commonly known as William and Kate, arrived in New Zealand yesterday. Along with their baby boy, Prince George, they`ll be spending three weeks in New Zealand and Australia. Because Princes William and George are second and third in line to the British throne, they need to beget special permission from the queen to travel on the same plane. And the excitement about their trip extends from their home in Britain to the nations it once ruled. New Zealand and Australia are now independent countries. But they are part of the commonwealth, linked to Britain by history, modern day cooperation and the symbolic monarchy, of which William, Kate and George are a part.

A new island has popped up in the Pacific, south of Japan, and it`s made friends with an older one to form an even bigger chunk of land. Here`s the new guy busting through the ocean surface last year. It`s a volcano that appeared in November. It was basically a stone throw away from its neighbor. Another volcano that last erupted 40 years ago.

Over the past few months, the new one spewed plenty of steam and ash and grew(ph). It had reached out and touched the older one by late December, and today the combined island is now more than six tenths of a mile across. It`s pretty hot stuff, so you don`t want to move there. But the bigger it gets, the longer it will take to erode in the Pacific. So, as long as it`s growing on the Pacific ring of fire, it`s growing more likely to stay around.

Time to take roll. And today we are calling out the Mount Rushmore state, the Hawk eye state and the tar hill state. In Sioux Falls South Dakota, we`ve got the Wolverines watching. Hello to everyone at William Middle School.

In Lisbon, Iowa, it`s the lions who were stuck in CNN STUDENT NEWS. Great to be online at Lisbon High School. And in Pfufftown, North Carolina check out the radars. Good to see our friends at Reagan High School.

April is autism awareness month in the U.S. The event aims to get people talking about the disorders to help the public better understand them. Autism rates continue to climb in America. It` believed to affect one in 68 children today. It was one in 88 children two years ago.

Experts aren`t sure why rates are increasing, and they don`t know what causes autism. But children who have the disorders are generally affected in three certain areas: the use of language, their behavior or how they interact with other people.

The extent of the disorders varies dramatically. One child with autism may be severely affected. Another symptoms may be more mild. And some children seem to outgrow some symptoms as they get older. So, each person with autism is unique.

By the amount of food we throw away in the U.S. some estimates put that at 40 percent. You wouldn`t think millions of Americans are going hungry. They are. And one reason - food`s wasted, is because many supermarkets won`t take imperfect-looking produce. Because many shoppers won`t buy it.

Sarah Ramirez rescues some of that food, gives it to people in need and earns the title of CNN Hero.
