Scientists who conducted the new study say this is a very slow process. Plants use less than 1 percent of the energy available to therm. But by hacking a plant39。 Specifically, scientists hacked the plant39。 Stephen Long is the lead author of the study. He pared a plant39。 The new study sped up the process.

Research published in the famous British journal Nature Communications has found that people who displayed higher levels of intelligence were almost 30 percent more likely to wear glasses. It is important to remember these are connections which are not proven causes. Scientists call this correlation. Just because something is connected to something else does not mean one of those things caused the other. And it39。Forget genes though. Plenty of proof shows wearing glasses makes people think you are more intelligent, even if you do not need glasses. A number of studies have found people who wear glasses are seen as smarter, hardworking and honest. Many lawyers use this idea to help win their cases. Lawyer Harvey Solves explained this. Glasses soften their appearance. He said sometimes there has been a huge amount of proof showing that people he was defending broke the law. He had them wear glasses and they weren39。Glasses are also used to show someone is intelligent in movies and on TV. Ideas about people who wear glasses have begun to shift. People who do not need glasses sometimes wear them for fashion only. They want to look worldly or cool. But not everyone is impressed by this idea, though. GQ magazine said people who wear glasses for fashion are trying too hard to look smart and hip (時(shí)髦的). However, that hasn39。People wearing glasses are smarter.B.Wearing glasses can make people cleverer.D.16
