This week, there is a lot of news about sickness and animals. A bird flu called H5N9 is making birds very sick in the U.S. Some ducks in California have it. Also, there is a big outbreak of tuberculosis in Kansas. This sickness can make people very ill, especially if they have other health problems. There is also a story about some very old puke that was found by a fossil hunter. It is from millions of years ago. Some sea lilies were eaten by an animal and then thrown up. Scientists are interested in studying this ancient puke. Lastly, there is a study about polar bears. They have a special grease on their hair that keeps snow and ice from sticking to them. When their hair is washed, they lose this special power. It's important to stay healthy, take care of animals, and learn about new discoveries in science. Make sure to wash your hands and listen to the news to stay safe and informed.
