Pluto's Republic, Dietary Shifts, Vaccine Confusion, Ancient Tech, and Renaissance DNA Mysteries

In Texas, a strange rule is causing trouble for professors. They can't teach certain ideas unless they get special permission. This rule is making it hard to discuss important topics like Plato's works. Some people think this is a bad idea because it limits what students can learn. It's like saying you can't talk about something unless someone in charge says it's okay. Meanwhile, the government is changing its food advice. They say people should eat real food and avoid too much sugar. But some experts who helped make these rules have ties to big food companies. This makes people wonder if the advice is really about health or just helping businesses. It's like when a friend tells you to eat healthy, but you find out they work for a candy company.Vaccines are also causing a lot of debate. The head of health is making changes that might make people less likely to get vaccinated. This could lead to more sickness. Some people think he doesn't trust the experts, which is a big problem. It's like if your doctor told you not to take medicine because they don't believe in science. Long ago, people were pretty smart. They made poison arrows to hunt. This shows that even without modern technology, people could be very clever. It's like when you learn something new and realize that people in the past weren't so different from us. Finally, scientists are trying to find DNA from Leonardo da Vinci. They swabbed a drawing that might be his. If they find his DNA, it could be a big deal. But it's not guaranteed. It's like trying to find a needle in a haystack, but with science.
