While every dog owner knows their dogs can read their moods perfectly, scientists have always been a piffle doubtful．Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria; we finally have some convincing evidence．

For their study, biologist Corson Miller and his team exposés eleven selected dogs to digital images of women that were either angry or happy．Half the dogs were rewired for touching the screen when shove a happy face, while the other half gilt their treat for selecting those that appeared angry．

Interestingly, the dogs were not provided with the entire face．Some dogs were show Ti only upper halves while the others observed lower halves．That's because the scientists believe humans show their eruptions on their equities face．

After some training ill．e how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions, the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face, the researchers concluded the dogs were smart-enough to read human emotions．

They also found those being trained to read angry expressions took a longer time to learn．They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly．However, once the smart dogs realized they were getting rewired, the trepidation seem end to disappear．In fact, the dogs had such a good time playing the computer "game" That scientists had a hard time keeping them away from the touch screens after the study was completed．

The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly．Since the touches careen models were all females, this confirmed what has been observed in previous studies-dogs are more efficient at reading facial expressions of people that are the serene gender as their owner．

1.How did the scientists conduct the experiment?

Most people know that Marie Curie was the first woman to win the Nobel Prize, and the first person to win it twice. However, few people know that she was also the mother of a Nobel Prize winner.

Born in September, 1897, Irene Curie was the first of the Curies’ two daughters. She studied in her mother’s school, and finished her high school education at the College of Sevigne in Paris.

Irene entered the University of Paris in 1914 to prepare for a degree in mathematics and physics. When World War I began, Irene developed X-ray equipment in military(軍事) hospitals in France and Belgium to help save the lives of wounded soldiers. Her services were recognized in the form of a Military Medal by the French government.

In 1918, Irene became her mother’s assistant at the Curie Institute. In December 1924, Frederic Joliot joined the Institute, and Irene taught him the techniques required for his work. They soon fell in love and got married in 1926. Their daughter Helene was born in 1927 and their son Pierre five years later.

Like her mother, Irene combined family and work. Like her mother, Irene was awarded a Nobel Prize, along with her husband, in 1935. Unfortunately, also like her mother, she developed leukemia because of her work with radioactivity（輻射能）. Irene Joliot-Curie died from leukemia on March 17, 1956.
