A 15-year-old student who invented a flashlight(手电筒) getting power from the holder's body heat is going home today from California with a big prize and a chance to do further research.

Ann Makosinski was the only Canadian among the four winners at Google's international science competition. Thousands of young scientists from around the world took part in the competition.

Winning the science and technology competition was "a surprise". Ann said, "I think it will have a great influence on my future."

Ann thanked her family for encouraging her interest in science and said that her first toy was a box of transistors(晶体管).

Ann's prize includes $ 25,000 and a "once in a-lifetime expericnce" from Google for her Hollow Flashlight, which has no moving parts or batteries.

The idea for the invention came from seeing unwanted batteries(电池) and her friend's experience. When Ann visited a friend in the Philippines, she saw the friend couldn't study when it became dark because there was no electricity or light. She saw the need for a flashlight that has no batteries - Hollow Flashlight.

In her project, Ann wrote "I made two flashlights that do not use any batteries or harmful materials. They do not create any noise and will always work. The flashlight needs at least a 5℃ temperature difference between the holder's body and the environment around to produce light."

A video of Ann explaining how she created the flashlight has been watched more than 1.4 million times on the Internet.

Though Ann was successful, she has not made a decision about her career path. Ann hope that she can find a way to join her love of film and science together.

The four winners were chosen from 15 final competitors from eight countries. The competition attracted thousands of students in 120 countries.

Heroes come in all shapes and sizes. Some heroes, like Lucca, are not even humans. Lucca is a 12-year-old US military (军队的) dog. On April 5, she received an award (奖) for her brave military service.

Lucca and her owner, Christopher Willingham, traveled to London, England, to receive the PDSA Dickin Medal. It is the highest award for service animals.Lucca is the first US military dog to receive the medal. “Lucca is very clever and had an amazing drive (干劲) for work as a search dog,” Willingham said. “I am lucky to have served with her.”

During her six years of active military service, Lucca completed more than 400 jobs. She was trained to find explosive devices (易爆装置). Lucca's skills protected the lives of thousands of people.

One day in 2012, she was searching for explosive devices with her trainer, Juan Rodriguez, as usual. Unluckily, she lost her left leg after walking on a device. She was quickly sent to hospital. Thanks to the doctors' help, Lucca was saved. During that time, Rodriguez remained at Lucca's side. “She had saved my life so many times — I had to make sure that I was there when she needed me,” Rodriguez said. “Within 10 days, she was walking again. Her fighting spirit was plain to see.”

Lucca doesn't work now and lives in California with Willingham and his family. “I'll do my best to keep her happy in her last years,” Willingham said.

Lucca is the 68th animal to receive the PDSA Dickin Medal since it was created in 1943. The award has been given to 31 dogs (including Lucca), 32 World War II messenger pigeons (信鸽), four horses and one cat.
