Can a window start a fire at your neighbour’s house? Yes — and it is happening more often than you think.

A special type of window glass called low-e glass is popular in modern homes. It can reflect heat like a mirror, so homes stay warm in winter and cool in summer. This sounds great, but there is a hidden danger.

If the glass is slightly curved, it can focus on one spot like a magnifying glass. Sunlight hits the window, bounces back, and gets very strong. This concentrated heat can easily set on fire things nearby — wooden fences, garden furniture, or even gas tanks.

One homeowner had a very frightening experience. Fires started three times in one week near his garden. He quickly moved his gas tank to a safer place. After some investigation, his neighbour’s low-e windows were the cause.

Experts say this problem is becoming more common as more people install energy-saving windows. If you have low-e windows, check if they are curved. A small curve can create a very big and dangerous problem for the people living next door.

Most people think of universities as peaceful places for studying. But some universities in California own weapons that are normally used by the military.

A 2021 law allows campus police to keep this kind of equipment if they say it is necessary for safety. The list of weapons includes grenades and very powerful sound devices that can cause pain and hearing damage.

One university used its loud sound device 71 times in just one year. Most of the time, it was used at student protests — not at dangerous criminals. This surprised and worried many people.

Students are not happy. Many feel frightened on their own campus and want this to stop. “We came here to study, not to face military equipment,” said one student. Some universities are now planning to get rid of their most dangerous weapons after pressure from students and teachers.

Critics say that using military equipment at peaceful student protests is wrong and creates fear instead of safety. Supporters say campus police need strong tools for emergencies.

The debate is not going to end soon, but the good news is that some universities are already listening to their students and making changes.

A delicious Italian pasta dish is helping to destroy life under the sea near Naples — and most people have no idea.

The dish is made with sea urchins — small round sea animals covered in sharp spikes. Sea urchins are very important for a healthy ocean. They eat algae and help many other sea creatures survive. Without them, the whole ecosystem can collapse.

But poachers are going out at night and collecting hundreds of sea urchins illegally to sell to restaurants. The money is good because the dish is very popular with tourists and locals. The problem is serious — scientists say some areas near Naples are already starting to run out of sea urchins.

Scientists want a national law to protect sea urchins and give their numbers time to grow again. At the moment, rules are different in different regions, and it is very hard to stop the illegal collecting.

Here is something important to remember: if you order fresh sea urchin pasta in a restaurant near Naples, it was probably caught illegally. Choosing not to eat it is a small but powerful way to help protect the ocean ecosystem for the future.
