    How about a trip to Indonesia? This country is a large group of islands located north of Australia. And it’s a beautiful place. It has thick, tropical rainforests and peaceful, sandy beaches.

    Just watch out for 10-foot-long lizards that can kill you with one bite. 

    That’s a pretty good description of Komodo dragons. They’re the largest lizards on Earth. And they can be deadly. They attack pigs, deer, cows—and, yes, sometimes humans. They rip big wounds in their prey with their sharp teeth. Each bite delivers a poison that makes their victims gush blood.

    But Komodo dragons aren’t just killers. Scientists think they have a very special power. 

    And that special power may teach us how to save millions of human lives.

    Indonesia is a country. It is a large group of islands. It has rainforests. It has beaches. It is located north of Australia. Are you ready to visit this beautiful place?

    If so, watch out for 10-foot-long lizards. They can kill you with one bite.  

    These lizards are called Komodo dragons. They’re the largest lizards on Earth. They attack pigs, deer, and cows. Sometimes they attack humans. Komodo dragons have sharp teeth. They rip big wounds in their prey to kill them.

    Komodo dragons are more than killers. Scientists think they have a special power. 

    That special power may save millions of human lives.

    Interested in an amazing vacation in a beautiful place with thick, tropical rainforests and peaceful, sandy beaches? Then head to Indonesia! This country is made up of a large group of islands located north of Australia. 

    Just beware of the 10-foot-long dragons that can kill you with one bite.  

    Dragons? Yes, Komodo dragons. They are the largest lizards on Earth, and they can be deadly. They attack pigs, deer, cows—and sometimes humans. As they rip huge wounds in their prey with their sharp teeth, they deliver a poison that makes their victims gush blood.

    But scientists say that, in addition to being ferocious killers, Komodo dragons may also have a very special power. 

    And that special power may be the key to saving millions of human lives.

Super Strong

    Komodo dragons are incredibly tough creatures. They often eat the rotting bodies of dead animals. These bodies are filled with tiny germs called bacteria. In most creatures, eating these bacteria would cause deadly diseases. But Komodo dragons don’t get sick. 

    How do these giant lizards fight off germs? Scientists recently found the answer. Komodo dragon blood contains special chemicals that protect it from bacteria. And that might be great news for humans.

    Komodo dragons are tough creatures. They often eat dead animals that have been rotting away for a while. These dead animals are filled with tiny germs called bacteria. Eating these bacteria would make most animals sick. But Komodo dragons don’t get sick from the bacteria. 

    Why don’t they get sick? Scientists just discovered why. Komodo dragon blood contains special chemicals. These chemicals protect it from bacteria. That might be great news for humans.

    How do these giant lizards fend off germs? Scientists recently found out: Komodo dragon blood contains special chemicals that protect it from bacteria. And that might be life-changing news for humans.

Helping Humans

    For most of human history, certain bacteria could be deadly. The tiny germs caused diseases like pneumonia and cholera. These diseases had no cure. If wounds became infected, there was nothing doctors could do. Even a small cut could kill a person.

    In 1928, scientists won a major battle against bacteria. They discovered antibiotics—medicines that kill germs. The first antibiotic was called penicillin, and it saved millions of lives.

    But recently some germs have become resistant to antibiotics. That means the antibiotics no longer work on the germs. 

    Every year these resistant germs kill nearly 700,000 people around the world. In 30 years, that number could rise to 10 million.

    This is where the Komodo dragon’s special blood comes in. Scientists want to use it to make new medicines. They hope these new drugs will be able to stop even the toughest infections.

    Certain bacteria can be deadly. The tiny germs can cause diseases, like pneumonia and cholera. For most of human history, these diseases had no cure. Also, if a wound became infected, doctors had no medicine for it. Even a small cut could kill a person.

    In 1928, scientists discovered antibiotics. These are medicines that kill germs. The first antibiotic was called penicillin. It saved millions of lives.

    Over time, some germs became resistant to antibiotics. That means antibiotics no longer work on the germs. 

    Every year, these resistant germs kill people. Right now, they kill about 700,000 people around the world each year. In 30 years, they might be killing 10 million people a year!

    Remember the Komodo dragon’s special blood? It might stop these tough germs. That’s what scientists hope. They want to use it to make new medicines.

    For most of human history, certain bacteria could be deadly. The tiny germs caused diseases like pneumonia and cholera, and there were no cures. Doctors also had no way to treat infected wounds. Even a small cut could kill a person.

    However, in 1928, scientists made a major breakthrough in treating disease and infection. They discovered antibiotics—medicines that kill germs. The first antibiotic was called penicillin, and it saved millions of lives.

    But over time, some germs changed to become resistant to antibiotics. These germs can’t be destroyed by antibiotics.

    Every year, nearly 700,000 people around the world die because of antibiotic-resistant germs. Thirty years from now, that number could be as high as 10 million.

    Could the Komodo dragon’s special blood prevent that from happening? Scientists are optimistic. They want to use the dragon’s blood to create new medicines that, they hope, will stop even the toughest infections.

Wonder Drugs

    The Komodo dragon isn’t the only fierce creature that may help save lives. The taipan is one of the most dangerous snakes in the world. Scientists think its poison might help stop wounds from bleeding. In Mexico, experts have been studying deadly scorpions. Poison from their stingers may help fight cancer. 

    One scary snake is already saving people with heart problems. The Brazilian pit viper has a poison that makes its victims pass out. That way the viper can eat them—head first. But that same poison can keep people alive. A medicine made with it helps treat a disease called high blood pressure. The medicine is used by 40 million people a year.

    Chances are the pit viper medicine is only the beginning. Bryan Fry is a scientist who studies Komodo dragons. He thinks strange creatures like the dragon have a lot more to offer. That’s where the “wonder drugs of tomorrow will be found,” he told the Washington Post newspaper. 

    So if you see a Komodo dragon or a pit viper, maybe you should say thank you—from a safe distance.

    Other fierce creatures may also help save lives. The taipan is a dangerous snake. Its poison might stop wounds from bleeding. Experts are also studying deadly scorpions. Their stingers have poison. It may help fight cancer. 

    One snake is already saving people. It helps people with heart problems. This snake is called the Brazilian pit viper. It has a poison that makes its victims pass out.

    So if you see a Komodo dragon or a pit viper, say “Thank you!” But say it from a safe distance.

    The Komodo dragon isn’t the only fierce creature that may have life-saving properties. The taipan is one of the most dangerous snakes in the world, but scientists think its poison might help stop wounds from bleeding. In Mexico, experts have been studying deadly scorpions to determine whether poison from their stingers can fight cancer. 

    One terrifying snake is already saving people with heart problems. The Brazilian pit viper has a poison that lowers its victims’ blood pressure, so they pass out. Then the viper eats them—head first. A medicine made with that poison helps treat a deadly disease called high blood pressure. The medicine is used by 40 million people a year.

    The pit viper medicine might be only the beginning. Bryan Fry, a scientist who studies Komodo dragons, believes that strange creatures like the dragon have a great deal more to offer. That’s where the “wonder drugs of tomorrow will be found,” he told the Washington Post newspaper. 

    So if you encounter a Komodo dragon or a pit viper, maybe you should say thank you—from a safe distance, of course.

This Mold Has Saved Millions

The surprising story behind penicillin, the medicine that changed the world 

Phil Degginger/Getty Images 

    Alexander Fleming wasn’t the neatest guy around. He worked as a scientist in London, and his lab was always a mess. He told his friends he kept it that way on purpose. He worked with tiny germs called bacteria. His job was to study how they grow. Keep the germs around for a while, and interesting things could happen.

    In the summer of 1928, Fleming came back from vacation. Dishes full of bacteria lay piled on his lab bench. He got out a magnifying glass and examined each one. They looked a little like last week’s dinner leftovers. Fuzzy green mold sprouted from the sides of the dishes. 

    Suddenly, one of the dishes caught his eye. It should have been covered in bacteria. But the mold had stopped the germs from spreading. “That’s funny,” Fleming said.

    It was more than funny. That disgusting green mold was penicillin. And it would soon be used to save millions of lives.

Big Discovery

A Wartime Weapon

    Fleming’s discovery wasn’t put to use right away. It took about 13 years to make medicine from the penicillin mold. 

    And that medicine came just in time.

    In 1944, World War II was being fought around the globe. Doctors struggled to help wounded soldiers. When the wounds became infected, doctors usually gave up. There was no way to stop bacteria from spreading. Usually, an infection meant death.

    That year, a factory in New York started producing penicillin by the gallon. By the war’s end, the medicine had been used to treat more than 100,000 soldiers.

    Since then, penicillin has been used to cure tuberculosis, pneumonia, scarlet fever, strep throat, and other diseases. It has probably saved about 200 million lives. 

    And we owe it all to the messy habits of Alexander Fleming.

    Fleming’s discovery wasn’t used right away. Scientists had to figure out how to turn the mold into a medicine. That took about 13 years. 

    But it was just in time.

    In 1944, many countries were fighting in World War II. Doctors tried to help wounded soldiers. But the wounds often got infected. There was no way to stop the bacteria from spreading. Usually, an infection meant death.

    That year, a factory in New York started making penicillin. The medicine was used to treat more than 100,000 soldiers. Then the war ended.

    Since then, penicillin has been used to cure many diseases. These diseases include tuberculosis, pneumonia, scarlet fever, strep throat, and others. It has probably saved about 200 million lives. 

    We owe it all to Alexander Fleming and his messy lab.

    Fleming’s discovery wasn’t immediately put to use. It took about 13 years for scientists to figure out how to make medicine from the penicillin mold. 

    But that medicine was ready just in time.

    In 1944, World War II was raging around the globe. Doctors struggled to help wounded soldiers, and they often gave up if the wounds became infected. Stopping the bacteria from spreading was nearly impossible. Thus, an infection usually meant death.

    That year, a factory in New York started producing penicillin by the gallon. By the war’s end, the medicine had saved the lives of more than 100,000 soldiers.

    Since then, penicillin has been used to cure tuberculosis, pneumonia, scarlet fever, strep throat, and other diseases—saving the lives of approximately 200 million people. 

    And we owe it all to the messy habits of Alexander Fleming.
