【推荐1】The Philippines, a tropical island nation in the Pacific, will now require by law all graduating students from elementary school to college plant 10 trees each before they can graduate.

The law was supported in the House and is now sent to the Philippines Senate for action, Supporters of the law see this as an opportunity for the Filipino youth to help deal with climate change and air pollution and build a greener environment for their generation.

“To this end, the educational system shall be a centre of spreading continuous use of natural resources among the young to make them socially-responsible citizens, The House bill stated, which was authored by representative Gary Alejano.

Alejano estimates that over the course of one generation the bill will be responsible for 525 billion trees planted.This comes from over 12 million students graduating from elementary school each year, 5 million from high school and 500,000 from college, equaling 175 million new trees planted each year.

The Philippines consists of 7,641 islands in Southeast Asia.Across those islands,deforestation has been a primary environmental issue.Agriculture has led to a significant drop in forested areas across the Philippines. Through the 20th century, forested area in the Philippines decreased from 70 percent to 20 percent.It is estimated that 24.2 million acres of forests were cut down from 1934 to 1988, primarily from logging.

The performance of this new law could set off a situation, by which the Philippines switches from net loss to net gain of trees, a simple and powerful message to the Filipino youth with the potential for long term positive influence.

【推荐2】As Internet users become more dependent on the Internet to store information, are people remembering less? If you know your computer will save information, why store it in your own personal memory, your brain? Experts are wondering if the Internet is changing what we remember and how.

In a recent study, Professor Betsy Sparrow conducted some experiments. She and her research team wanted to know the Internet is changing memory. In the first experiment, they gave people 40 unimportant facts to type into a computer. The first group of people understood that the computer would save the information. The second group understood that the computer would not save it. Later, the second group remembered the information better. People in the first group knew they could find the information again, so they did not try to remember it.

In another experiment, the researchers gave people facts to remember, and told them where to find the information on the Internet. The information was in a specific computer folder (文件夹). Surprisingly, people later remember the folder location better than the facts. When people use the Internet, they do not remember the information. Rather, they remember how to find it. This is called “transactive memory (交互记忆)”

According to Sparrow, we are not becoming people with poor memories as a result of the Internet. Instead, computer users are developing stronger transactive memories; that is, people are learning how to organize huge quantities of information so that they are able to access it at a later date. This doesn’t mean we are becoming either more or less intelligent, but there is no doubt that the way we use memory is changing.

【推荐3】Why do men live a shorter life than women? The latest research indicates that men’s hearts going into a rapid decline when they reach middle age could be the cause.

The research of ageing on the heart has shown that women’s longevity may be linked to the fact that their hearts do not lose much pumping power with age.

“We have found that the power of the male heart falls by 20-25 percent between 20 and 70 years of age,” said the head of the study, Samantha of Liverpool John Moores University in the UK.

“Within the heart there are millions of cells which make it beat.Between the ages of 20 and 70, one-third of those cells die and are not replaced in men ,” said Samantha.“This is part of the ageing process.”

What amazes scientists is that the female heart suffers very little loss of these cells. A healthy 70-year-old woman’s heart could work almost as perfectly as a 20-year-old one’s.

“This gender (性别) difference might give the reason why men live shorter than women,”said Samantha.They studied over 250 healthy men and women between the ages of 17 and 80, who are mainly healthy persons so as to reduce the influence of disease.“The team has yet to think about why ageing suffers a greater loss on the male heart,” said Samantha.

But there is also good news — men can enjoy the health of their hearts with regular exercise.Samantha stressed that women should also take regular exercise to stop their leg muscles getting weaker as they age.
