Picture the scene: It’s midnight. You’re very hungry after studying for a long time. Then you see a nice pie in the fridge. Do you eat it? It seems that you shouldn’t, for many reasons, including its influence on your studies.

Scientists have long known that eating late at night can make us gain weight. But now a new study has shown that late-night eating can also have a bad influence on our brains — it might hurt our ability to learn new things and store memories.

“We believe that late-night eating may affect (影响) our learning by affecting the parts of the brain that control learning and memory,” Dawn Loh, PhD, a project scientist at the University of California, Los Angeles, said, “We believe the timing of when we eat is the main cause of the damaged (受损的) memory.”

For the study, the researchers looked at mice with strict feeding plans. For two weeks, the mice were either allowed to eat during the time when they are usually the most active, or during the time when they usually sleep. The mice received the same amount(数量) of sleep and calories.

Then the researchers tested the brains of the mice. In one test, the researchers tried to find out whether the mice could remember that a room was connected to an electric shock(电击) after 24 hours had gone by.

The researchers noticed that, when the mice were put in the room again, those mice that ate when they should have been sleeping were less likely(可能的) to get scared than those mice that ate during usual hours. It means that they didn’t remember.

So think twice before the midnight snack — it might be bad for more than your weight.

What will the future be like? It’s possible that we may often fly up into space! Out of all the coolest inventions of the year 2004, Time magazine chose SpaceShipOne as the best.

SpaceShipOne is a 6-metre-long white spacecraft. On June 21, American pilot Mike Melvill flew it to space and back—about 100 kilometres up into the sky. Some might say it’s not a big success. You know, people went to the Moon years ago.

Well, SpaceShipOne is special because it is the first spaceship that wasn’t made by the government. It was built and sent up by a private US company. Lots of people want to travel in space and think that it is an enjoyable trip. But it’s too expensive. American millionaire Dennis Tito paid almost US $20 million to become the first space tourist to visit the International Space Station in 2001. So private companies began to think of making their own spacecraft to take other tourists up into space.

Certainly, the success of SpaceShipOne is a good start. In the next 10 to 15 years, if you

pay $20,000 to $100,000, you could fly high above the Earth in a special suit.

Can you imagine having your own spacecraft in your garage and taking it to space at the weekend?
