    Are you a happy person most of the time? Or do you easily get angry sometimes? Everyone has a different temperament (脾气). It is usually believed that both genes (基因) and environment may affect people's temperaments in different ways. But now scientists have found that the season of birth also plays a role.

    Scientists from Budapest, Hungary, studied 400 university students. In the study, the students needed to finish a questionnaire (问卷).The purpose of it was to find out which of four kinds of temperaments they most had. From the questionnaire, scientists found that the students always answered something like "my mood often changes for no reason" and "I love to deal with new projects, even if it is risky". These answers were then matched with their birthdays.

    They discovered that people born in summer easily change between sad and happy moods compared to people born in winter. Those who always feel positive are mostly born in spring and summer.

    The study also found that those born in autumn less probable had a mood of depression which may easily drive them to cry, while those born in winter were not easier to be angry.

    Scientists said that this was probably because the seasons had an influence on certain chemicals in the human body. And the chemicals are important to control people's moods even in adult life.

    "It seems that when you are born may increase or decrease your chance of developing certain mood disorders (紊乱)," lead scientist Xenia Gonda told The Telegraph.

    How do you light up the night sky? The answer is by using electricity. But did you know that nature can glow (发光), too?

    Scientists have found many glowing living things. Most of them live in the ocean. Some use their lights to talk to each other. Others use them to hunt, to mate (交配) or to protect themselves. The vampire squid (幽灵蛸), for example, uses a cloud of light to scare enemies.

    Scientists around the world are looking at this kind of light for new ideas. In 2013, the US company Gleaux said it has created the world's first light-producing plant, the Daily Mail reported. It is a genetically-modified (转基因的) plant. It can glow like a firefly.

    Alexander Krichevsky, the company's founder (创始人), and other scientists hope that in the future, glowing plants could replace lamps and glowing trees could light up highways. Krichevsky also hopes the technology could be used in farming. Farmers could know when their crops need water or are ready to be picked if they glow.

    While Gleaux is working on glowing plants, the French company Glowee is trying to use glowing bacteria (细菌) to light up shop windows and street signs. It's the same type of bacteria that cause a type of squid to light up, New Scientist Online reported.

    "Our goal is to change the way we produce and use light," said Glowee founder Sandra Rey. "We want to help reduce the 19 percent of electricity consumption (消耗量) that is used to produce light.
