Volunteers also walked the dance floor with donation boxes to collect more money
9、.The Kanduns are living with Keishas grandparents until they can move into their new house. The whole family attended the dance; then they went on stage to thank the crowd. Rebuilding has already begun, and the family hopes to move back in time for the holidays.“We appreciate the help so much that I
10、 cannot even put it into words,” said Mary Kandun, Keishas mother. “We have always loved the school, but we never expected this kind of generosity. You should all be proud of your school for showing so much heart.”The Kanduns four-bedroom home was empty on August 14 when it caught on fire after bein

16、Worldwide, more than two billion people lack access to essential life-saving supplies, such as blood and vaccines（疫苗）. In the African nation of Rwanda, for example, several remote health clinics do not have sufficient quantities of blood and other healthcare products. A company called Zipline is try
17、ing to address this problem. It uses drones（无人机）to transport medical supplies around Rwanda. A drone can now deliver medicine in 30 minutes.Drones are also assisting emergency organizations after natural disasters. In 2015, for example, a powerful hurricane destroyed thousands of buildings in the Pa
18、cific island nation of Vanuatu. Around 75,000 people lost their homes, and at least 15 died. After the storm, drones photographed the damage. These surveys helped emergency workers assess the situation quickly and answer important questions: Which areas were hardest hit? Were crops damaged? What roa
19、ds were affected?Drones are also helping to protect wildlife populations in parts of Africa and Asia. Every year, poachers（偷猎者） kill thousands of elephants, rhinos, and other endangered animals. To stop them; the environmental organization World Wildlife Fund is using drones to find where poachers a
20、re hiding and if they are carrying weapons. Equipped with infrared video cameras, drones can easily identify people and animals at night. These drones are not only helpful, they are affordable.As well as finding poachers, drones can be used to track animals. Scientists at Liverpool John Moores Unive
21、rsity （LJMU）plan to employ drones for an ambitious conservation project: documenting the worlds wildlife. The long-term project will start with scientific surveys of animal populations. And animal species can then be identified using special software.Ironically（讽刺地）, a tool originally created for mi

Researchers have started imitating thi
25、s super skill with an artificial-intelligence-based detective tool. In a study published in February in PLOS ONE, a multinational team reported an AI-powered system that is as accurate as trained dogs at correctly identifying cases of prostate cancer from urine samples. Andreas Mershin, a research s
26、cientist from Massachusetts Institute of Technology, wants to eventually integrate the technology into smartphones: There would be a tiny sensor in the phone with AI software running in the cloud.Prostate cancer, the second most deadly cancer in men worldwide, is difficult to detect. The most widely
27、 used test can miss 15 percent of cancers. Trained dogs, on the other hand, were able to identify patients with prostate cancer from urine samples more than 96 percent of the time. Yet dogs can get bored and tired, so researchers want to develop an AI system that works more consistently.Living cells
28、 produce chemicals that come out from the skin, blood, urine and breath. Artificial noses, including the Nano Nose that Mershin and one of his colleagues developed, can already detect those chemicals at the same parts-per-billion concentration as dogs. The team added to the chemical sensing an artif

Mershin plans to train th
