Ants Invade!

Ants Invade!

Scientists have made some amazing discoveries about one species of ant

One type of South American ant is spreading around the world and is living in huge super-colonies. Not only that, but these natural fighters seem to know they are family and get along, according to the latest scientific findings.


Super-colonies of Argentine ants may be separated by oceans, but they still recognize each other.


The light brown Argentine ants are originally from South America. Over the years, the Argentine ant has moved to other parts of the globe, possibly by hiding in people's luggage and in cargo. This hasn't always been a good thing since the insects can destroy local plants and affect what animals in that area eat.

Ants are fierce fighters. They protect their territory from invaders, including other types of ants and insects. But Argentine ants, though they live on separate continents, don't fight when they come together, scientists say. "Our research found Argentine ants from three continents were rather friendly, and not hostile towards each other," researcher Eiriki Sunamura told the New Zealand Herald.

Are Ants Taking Over?

There are three known super-colonies of Argentine ants. In Europe, one super-colony is located along the Mediterranean Sea. It is believed to be 3,700 miles long. That's even wider than the United States. Another super-colony is located in California. It covers about 560 miles, or about half of the California coast. The third super-colony is on the west coast of Japan.

Scientists in Japan and Spain have discovered that the insects in the three super-colonies share similar chemical profiles. This helps them recognize one another. To prove this, the scientists matched each super-colony with ants from a different colony in a similar part of the world. The Mediterranean ant colony couldn't get along with a smaller one from Spain. And the colony from the west coast of Japan couldn't get along with ants from another area in Japan. But when the ants from the three super-colonies came together, they got along just fine. In fact, they acted like old friends. And how do old ant friends greet one another? By rubbing antennas to say hello.

All in the Family

The scientists think that the Argentine ant super-colonies are one big family. Because they have similar chemical profiles, the scientists believe they are genetically related. The ants recognize each other by the chemical makeup of their outer shells.

Max-I think the Argentine ants are good ants because it only fights with other colonies, but even the Argentine ants’ colonies are separated into different places, they won’t even fight. I think it is a special kind of ant. But the colonies are too big, they are going to take over the world!

Swine Flu(H1N1)‏

April 27, 2009

What is Swine Flu?
TFK answers this and other questions about the flu outbreak
By Nellie Gonzalez Cutler
http://www.timeforkids.com/TFK/kids/news/story/0,28277,1894138,00.html

On Monday, the World Health Organization (WHO) said that 40 cases of swine flu have been confirmed in the United States. People have fallen ill in several states. All of those who have come down with the flu have either recovered or are recovering. Many of them visited Mexico recently.


The flu is taking a serious toll on Mexico. Officials believe that swine flu may have sickened 1,614 people since April 13. The virus is suspected to have caused more than 100 deaths. The Mexican government has closed all public schools and canceled hundreds of public events in the country's capital, Mexico City. Soldiers handed out six million face masks, hoping the masks will stop the spread of the virus.

Governments around the world are taking steps to stop the spread of the illness. They are questioning travelers and encouraging citizens to take precautions. The WHO is keeping a close watch on the situation. No one wants the illness to become a pandemic (pan-dem-ik), or worldwide outbreak. In 1918, the severe "Spanish flu" killed an estimated 40 to 50 million people worldwide. But the world is better prepared for a flu outbreak today. Antiviral drugs can help fight swine flu. Doctors and hospitals are better equipped than they were 100 years ago.

Here are answers to questions you may have about swine flu:

What is swine flu?
Swine influenza, or flu, is a respiratory disease of pigs. Type A influenza viruses cause it. Humans do not normally get swine flu. But when they do, infections are believed to spread from person to person. The Centers for Disease Control and Preventions (CDC) has determined that swine flu is contagious.

How does swine flu spread?
Flu viruses are mainly spread when someone who is infected coughs or sneezes near another person. Droplets from an infected sneeze move through the air. Sometimes people become infected when they touch a surface that is infected and then touch their mouth or nose.

Can I get swine flu from eating pork?
No. The flu is not spread through eating or preparing food.

Are there medicines to treat swine flu?
Yes. Your doctor can prescribe drugs that will help you feel better.

Should I be worried?
Officials say that the swine flu situation is serious. You should take precautions, but there is no need for you to worry. On Sunday, the U.S. government declared a public health emergency. The government is working hard to determine how best to deal with the flu outbreak. More than 12 million doses of flu-fighting medications are being shipped to states. President Barack Obama said on Monday that the threat of spreading swine flu infections is a matter of concern but "not a cause for alarm."

What can I do?
• Wash your hands often with soap or use an alcohol-based hand sanitizer.
• Avoid touching your eyes, nose or mouth.
• Cover your mouth with a tissue when you cough or sneeze. Then throw the tissue in the trash.
• If you don't have a tissue, cough or sneeze into your arm rather than your hand.
• Let your parents know if you are not feeling well.
• Stay home from school if you are sick.



Max-I think that swine flu is a dangerous disease, because of some people spreading diseases to other people, until many people in the country get the disease and we need to move away. So you can wash your hands when coughing and sneezing, and stay away from other people, and don’t go to places with too many people inside.

Return of the Blue Whales‏

Return of the Blue Whales
After decades away, the giant marine mammals have been spotted in the waters off Alaska
By Suzanne Zimbler
Blue whales living in the Pacific Ocean used to travel north toward Alaska for food every spring. But around 1966, the giant mammals stopped making the trip north. Now, after more than 40 years, scientists say blue whales are returning to the northern waters.
Blue Whales' Blue Tale
Blue whales are the largest animals on the planet. The average blue whale is about 80 feet long. That is twice the length of a large yellow school bus. But being huge has not kept these animals safe from harm.
In the early part of the 20th century, an estimated 350,000 blue whales swam the world's oceans. Then whalers began hunting the animals for their blubber. Blubber is a thick layer of fat under the whale's skin that is boiled down to make oil. The animals were hunted almost to extinction. In 1931 alone, more than 29,000 blue whales were killed.
Hunting blue whales was banned in 1966. But recovery has been slow. According to the American Cetacean Society, there are now between 8,000 and 14,000 blue whales in the world. About 2,000 blue whales live in the Pacific Ocean, off the coast of California.

A Whale of a Trip
For decades, blue whales living in the Pacific Ocean have not swum north. "No one had seen blue whales in these waters since the end of whaling," says scientist Jay Barlow. Then, in 2004, three blue whales were spotted in the waters off Alaska. Scientists compared pictures of these animals with pictures that had been taken of blue whales in the waters off the coast of California. They realized that at least one was a match. The same blue whale that had been photographed near California was now swimming near Alaska. Researchers now have evidence that 15 blue whales seen off the coast of Canada and in the Gulf of Alaska are part of the California group of 2,000 animals.
Scientists believe the animals may be traveling north in search of food. Blue whales eat four tons of krill, a tiny shrimplike animal, every day. A change in ocean temperature, which normally occurs every 10 years, may have pushed the krill farther north. "When the food dries up, these animals wander over enormous ranges," said Bruce Mate, director of the Marine Mammal Institute at Oregon State University.



Max-Now that blue whales are getting fewer and fewer, we need to protect them! I think that the whalers are evil, they are doing bad things to the whales, even killing them because they want to eat the whale’s fin! Because of this reason, in the past few months, I saw advertisements on the TV propagate to the people not to kill whales.

Largest Sandstorm in History?

Largest Sandstorm in History?

A huge sandstorm is covering parts of Iraq

By Joyce C. Tang
http://www.timeforkids.com/TFK/kids/news/story/0,28277,1909339,00.html


One of the worst sandstorms in history has blanketed Iraq for more than a week. On the streets, the fine dust has coated everything. People's hair and clothes are a rusty orange color. Residents aren't leaving their homes without the protection of face masks.

A sandstorm, also known as a dust storm, occurs when high winds blow loose sand and dust. Last Sunday, a NASA satellite took pictures of the giant sandstorm at its height. Some parts of the storm were so thick that the ground below was not visible. The sandstorm has caused health problems, delayed flights, and interfered with local businesses and government activity. Even U.S. Vice President Joe Biden had to call off plans to visit the Iraqi president. As many as 300 people have complained of difficulty breathing at a hospital in Baghdad, the nation's capital.

Because visibility is only a few yards, the Baghdad airport was shut down. Police are directing traffic on the streets. It's not only the outdoors that is dangerous, however. The dust creeps under doorways and through cracks in windows, covering the insides of buildings as well. It even leaves an iron–like taste in people's mouths.


Rain, Rain, Come Again

Iraq is a desert country, so sandstorms are common. The situation this year has been worse because of several recent years of drought. Little rainfall has left the land drier than usual, causing it to become dustier. The dust has even blown over to Iran and Saudi Arabia—two neighboring nations. Government offices in Iran, and schools in Tehran, Iran's capital, have declared Tuesday and Wednesday public holidays so they could close down because of the storms.

Experts say that sandstorms have become more frequent in Iraq. They blame the drought, the growth of cities into areas that once grew crops, and military vehicles removing the upper crust of sand. Sandstorms usually last for a day, but this one has stretched on for more than a week. It may end up being the largest dust storm in modern history.


Max-I wish that the sandstorm will weaken its power after a few days so that the people in Iraq will become healthier and not go to the hospital. If the sandstorm became stronger, some people will even die of difficult breathing. I wish there is no more sandstorms stronger than this one.

漂鳥營 Fun things and What I have learned

漂鳥營 Fun things and What I have learned

Fun things:


July 10th, 2009

1. At the first day, we first went to the bottom of the bridge to make a stone kiln. First, we picked many pieces of wood from the beach. Then we get some stones from the bottom of the bridge to make the kiln. We first put bigger stones on the ground, and then we put smaller and smaller stones on top of the big stones. Before that, we put a long stone on top of two big stones to make a door. When the kiln is done, we put the pieces of wood and some old newspapers, and then lit the fire. We waited about 20 minutes and we put our yam and eggs in. During that time, some other team was trying to throw some stones to hit the bamboo stick on the other side. So we tried it too, but we failed. At last, only two competitors get a drink for a prize. Finally, the yams and eggs are cooked so we eat it. Our team only ate the yams because the eggs are over-cooked.

2. At the evening a man let us see a slide. Inside there are 80 pictures, mostly about birds, but some are locations too. At this one hour slide, we studied about many kinds of birds and some of the locations too.



July 11, 2009

1. This morning, we went to a field to play some games. We walked and heard the teacher say lots and lots of plants, and we saw lots and lots of birds with the teacher’s microscope. When we got to the field, we played a lot of games about running and a game that we dodge obstacles blind-folded. It is very fun!

2. At the afternoon, we go to a place to walk on a piece of steel wire. I was the 10th one to challenge it. At first, I climb a tall tree. It was very dangerous, and it was scary. Then I go on by the first part of the steel wire walking. At this first part, there were another two steel wires to hold the hands, so I passed the first part quickly. At the second part, there are only a few strings of rope, so it was very scary because of only a rope to hold on. But I fell only once, and passed the second part quickly.

3. At the night, we made some handmade soap. First we pour melted soap in the container. Then we put some tea tree branches and dry roses in the container. We put them for one night. (continued in next day)


July 12, 2009

1. When we woke up today, we quickly dressed up and brushed our teeth. We went down to see our handmade soap. After everybody came down, we put our soap out of the container. It is very beautiful.

2. We went to the field again at the morning. We played a tower defense, and we played another game called Frog King. At Frog King, we need to hop and avoid the other people hitting us when jumping. We didn’t win before because they are too strong. At the tower defense we were been separated into two teams, and try to avoid been hit by the enemy team. In three matches, we won two matches and won. We first get the drinks and they used a large truck to take us back. Then we went to a place behind the hotel to play another game. When we went up the hill, we saw an 8-foot long see-saw! At my turn, I swing down the hill, and it was scary because of too high. After we all tried, we went down to eat lunch.


What I Have Learned:

At these three days, I have studied about plants and birds, and I know how to look at stars. I made a lot of things and I know, it takes effort to do it. And it was very fun at this camp, that I wish I can join it again in the next year.

Night At The Museum

July 4, 2009

Night At The Museum
By Max      Age 10
Today we watched a good movie called “Night At The Museum”. It was very funny and the story was talking about Larry the new night guard and the ALIVE animals and people”they are only alive at night”.
At first, Larry was a poor man and he didn’t have a job. So one day he went in the museum because there was a job in the museum. So he became a new night guard. Then he waited and waited, and suddenly the things are all alive! Larry didn’t know this situation will happen at night so the dinosaur Rex chased him, then he was been tied up with the small western cowboys. Although he broke the ropes, the English soldiers shooted many fire arrows. He ran away but the Chinese soldiers chased him. He did some magic trick tricks, but he didn’t do it well. So they still chased him and almost killed him. Then he went to the animal zone when he accidentally shut himself up. The lions, elephants, giraffes and some animals came to him but didn’t bite him. Then Dexter the monkey showed up. He ripped the guide book, peed on Larry, and took his keys. So he ran away and found Teddy Roosevelt. He took him to find DumDum. He wanted some gum, but Larry didn’t have any so he ran. Then Teddy took Larry to see Sacagawea because he wanted to explore her history. After that, it is almost dawn. The people and animals all went back to their positions. Larry saw a teacher taking her students so he went to find the teacher. The teacher said he needs to read more books about their history. So Larry started to read about history, and surfed in the Internet. That afternoon, Larry got a lot of stuff to the museum. After the people left and the exhibits all moved, Larry first drove a motor car to let Rex chase. Then he separated the cowboys and soldiers to stop them fight. He also gave Dexter some baby keys to let him believe it was his keys. Then he gave DumDum a very big ball of gum to eat. But Dexter took his keys when he was walking! So Larry chased him until Dexter used a fire extinguisher to spray his mouth. At the same time, Roosevelt came to Dexter and gave the keys back to Larry. Then the cavemen saw the fire extinguisher and ate the powder! They ran out the museum. When Larry chased them, the sun rises up. The cavemen turned into wax. When the boss saw it, he fired Larry. But Larry wanted a second chance, and the boss accepted him. At night, Larry took his son Nick to the museum. But when the time is 6:00, the exhibitions didn’t come alive! So he went to the office and saw the old night guards robbing the board. He fighted with them but they ran away. Suddenly the exhibitions are alive and Larry had a meeting with them. Finally they started to chase them. The leaders of the cowboys and soldiers sat in the motor car. Larry rode Rex, and the other exhibitions are behind him. But Larry can’t chase the night guards, so he said a magic word to let the horses stop. Finally he took the board back to the museum and gave to King Tut to call all exhibitions back. Then the exhibitions had a great party!
