2 . Some people, regardless of what they lack—money, looks, or social connections—always show with energy and confidence. Even the most doubting individuals find themselves attracted with these lovely personalities. These people are the ones you turn to for help, advice, and companionship. You just can’t get enough of them, and they leave you asking yourself, “What do they have that I don’t? What makes them so attractive?”

The difference? Their sense of self-worth comes from within. Attractive people aren’t constantly searching for value, because they’re confident enough to find it in themselves. There are certain habits they pursue every day to keep this healthy view. Since being attractive isn’t the result of dumb luck, it’s time to study the habits of attractive people so that you can use them to your benefit.

Get ready to say “hello” to a new, more attractive you. Attractive people treat everyone with respect. Whether interacting with their biggest shoppers or a server taking their drink order, attractive people are unfailingly polite and respectful. They treat every one with respect because they believe they’re no belief than anyone else.

They follow the golden rule. One person loves public recognition, while another hates being the center of attention. The golden rule is to treat others as they want to be treated. Attractive people are great at reading other people, and they adjust their behaviors and styles to make others fell comfortable.

Bringing it all together, attractive people have simply perfected certain appealing qualities and habits that anyone can adopt as their own. They think about other people more than they think about themselves, and they make other people feel liked, respected, understood and seen. Just remember: the more you focus on others, the more attractive you’ll be.

4 . The worldwide 20th century “Green Revolution”, which saw huge year-by-year increases in global grain yields (产量),was fueled by the development in the 1960s of new high-yielding dwarfed (矮小) varieties known as Green Revolution Varieties (GRVs).

These dwarfed GRVs are common all over the world in today’s wheat and rice crops. Because they are dwarfed, with short stems, GRVs devote relatively more resources than tall plants to the growth of grains rather than stems, and are less likely to suffer yield losses from wind and rain damage. However, the growth of GRVs requires farmers to use large amounts of nitrogen fertilizers (氮肥) in their fields. These fertilizers are costly to farmers and cause extensive damage to the natural environment. The development of new GRVs combining high yields with reduced fertilizer requirements is thus a global agricultural goal.

Researchers at the University of Oxford and the Chinese Academy of Science have discovered for the first time a gene that can help reach the goal. Comparing 36 different dwarfed rice varieties, the researchers identified a novel natural gene that helps increase the rate at which plants make use of nitrogen from the soil. This gene, called GRF4, can increase the amount of a protein (蛋白质) in plant cells. GRF4 is actually a promoter that encourages the activity of other genes—genes that promote nitrogen uptake (摄入). Professor Harberd said, “Increasing GRF4 levels could contribute to an increase in the grain yields of GRVs, especially at low fertilizer input levels.”

The researchers say the latest rice variety containing GRVs should now become a major target for farmers in increasing crop yields and fertilizer use efficiency, with the aim of achieving the global grain yield increases necessary to feed a growing world population at a reduced environmental cost. It is very urgent at the moment.

Professor Harberd added, “This study is an example of how studying fundamental science objectives can lead rapidly to potential solutions to global challenges. It shows how the discovery can enable chances for food security and future new green revolutions.”
