Perhaps every old generation since ancient times has complained about young people, and today is no different. Isn’t it clear that compared with our glorious selves, kids these days are self-absorbed social network addicts?

However, this summer, my impression of today’s kids has been restored by the story of Rachel Beckwith. She could teach my generation a great deal about maturity and unselfishness — even though she’s just 9 years old, or was when she died on July 23.

At age 5, Rachel had her long hair shorn off and sent to Locks of Love, which uses hair donations to make artificial hair for children who have lost their own hair because of cancer or other diseases. After that, Rachel announced that she would grow her hair long again and donate it again. And that’s what she did.

Then when she was 8 years old, her church began raising money to build wells in Africa through an organization called charity: water. Rachel was astonished when she learned that other children had no clean water, so she skipped her ninth birthday party. Rachel set up a birthday page on the charity: water website with a target of $300. Instead of presents, she asked her friends to donate $9 each to charity: water. Finally Rachel raised only $220 — which had left her just a bit disappointed.

Then, on July 20, a serious traffic accident left Rachel critically injured. Church members and friends, seeking some way of showing support, began donating on Rachel’s birthday page — charitywater.org/Rachel — and donations reached her $300 goal, and kept rising.

But Rachel couldn’t hear that she had raised beyond the $47,544 that the singer Justin Bieber had raised for charity: water on his 17th birthday. “I think Rachel would have been overjoyed for she secretly had a crush on (迷恋) him,” Rachel’s mom said.

When it was clear that Rachel would never regain consciousness, the family decided to remove the life support system. Her parents donated her hair for the final time to Locks of Love, and her organs to other children.

Word about Rachel’s last fund-raising spread. Contributions poured in, often in $9 each. The total donations soon topped $100,000, then $300,000.

This is a story not just of one girl, but of a young generation of outstanding problem-solvers working creatively.

An electric signal can trick a monkey’s brain into believing the animal’s finger has been touched.

Touch something, and your brain knows. The hand sends signals to the brain to announce contact was made. But that feeling of touch may not require making actual contact, tests on monkeys now show. Zapping brain cells can fool the animal into thinking its finger has touched something.

A person who has lost a limb or become paralyzed may need an artificial limb to complete everyday tasks. But such patients may not truly feel any objects they hold. The new findings point toward one day creating a sense of touch in those who use such artificial limbs. Psychologist Sliman Bensmaia of University of Chicago worked on the new tests. His team’s findings appeared on October 14 in the Proceedings of the National Academy of Sciences of the United States of America.

The sense of touch is crucial to everyday tasks: People without it may have difficulty cracking an egg, lifting a cup or even turning a doorknob. That’s why restoring it is a major goal for designers of artificial limbs.

In their new study, Bensmaia and his co-workers worked with rhesus monkeys (恒河猴). The scientists implanted electrodes (电极)--- small devices that can detect and relay an electrical signal—into the animals’ brains. The scientists used the electrode data to identify which neurons had become active. Then the scientists used the implanted electrodes to zap those same neurons. And the monkeys reacted as though their fingers had been touched. In fact, they hadn’t.

The monkeys couldn’t use words to tell the scientists what they had felt. Instead, they communicated by looking in a particular direction—just as when they had really been touched.

The new findings show how touch-sensitive devices could be built. The new study also offers “ a nice clear pathway” for figuring out how to restore a sense of touch to an amputee(被截肢者) or someone with a injury of spinal cord.

The study shows how artificial limbs might be connected to the brain so that a person can “feel” with such a prosthesis (假肢). But such a supersensory device doesn’t exist yet and scientists have a lot of work to do before people will benefit from it. Researchers must first figure out whether the electrodes would work in people in the same way they do in monkeys.

“ I think the foundation is laid for human trials,” Bensmaia said.
