Robotic Exoskeletons

Thanks to robotic exoskeletons, victims of spinal cord（脊髓）injury have a new reason to hope. Robotic exoskeletons, consisting of metal legs, motors, batteries, wiring, a controller and a set of strips work together like the user’s bones, muscles and nerves-outside the body. Fastened into an exoskeleton and supported by sticks, users can direct the machinery to take them where they want to go.

In addition to partly restoring mobility, robotic exoskeletons offer the significant mental and physical health benefits of standing up and moving. Just being able to get up from a wheelchair gives patients a more natural, positive view of the world. It also helps relieve pressure on patients’ skin and reduces the danger of pressure sores. Standing upright strengthens a disabled person’s muscles and bones, improves heart health，and reduces certain other health complications（并发症）. And it may actually result in partial nerve repair, something that can only happen when a patient is able to move.

As promising as this technology is, however, it is no simple cure-all for paralysis（瘫痪）or its complications. The motion is not accurate compared with natural walking, and exoskeletons are not easy to use, especially on surfaces that are not smooth. They are very expensive, costing about US$100000. Health insurance plans and government programs may not cover the cost of buying one.

Nevertheless, robotic exoskeletons，and access to them, will continue to improve. As with much modern technology, robotic exoskeletons will likely become more capable and easy to use, even as their cost goes down. Governments and insurers may increasingly see that the health benefits of these walking machines outweigh the costs, making it easier to fund them. Perhaps the day will come when nearly everyone paralyzed by spinal cord injury will be able to “walk” again.

Museums Rethink What to Do with Their African Art Collections

Recently, a discussion is happening in museums around the world over the volume of African art in their collections. Officials in Germany and the Netherlands have announced plans to return art and artifacts（文物）taken from Africa during the    1    period. And more museum staff are meeting on the topic across Europe.

According to the most commonly    2    figures from UNESCO（United Nations Educational, Scientifie and Cultural Organization）, 90% to 95%of sub-Saharan cultural artifacts are    3    outside Africa. Many were taken by force long ago and ended up in museums across Europe and North America.

At the Africa Museum in Belgium, director Guido Gryseels says 85 percent of the-museum’s collection comes from the Congo-the site of Belgium’s    4    colony in Central Africa. For decades, Congolese leaders have asked for these objects to be returned. Most of their    5    , and those by African countries to other museums, have been refused.

But recent events in Europe have    6    the possibility of returns at a much larger scale. In addition to the plans announced in Germany, last year France conducted a study of how much African art French museums are holding and made    7    about what to do with it.

The study recommended the return of a wide range of objects taken by force. The suggestion got mixed    8    in France, where there are at least 90000 African items in museums.

In France, some people have suggested returns could leave shelves    9    in French museums. Cecile Fromont, a French historian of Central African art, says that’s not going to happen. One way of thinking about it, she says, is that more African art can go on display.

However, Guido Gryseels of the Africa Museum in Belgium    10    that attitudes are changing. He says he’s in discussion with the Congo to return works.
