NASA astronaut Frank Rubio set a new record on Monday, Sept.11 for the longest single spaceflight conducted by a U.S. astronaut, after spending 371 days in space, and his mission isn't over. Rubio originally was scheduled to spend six months in space before his mission was extended to more than a year. Throughout his record-breaking mission, Rubio contributed to several science experiments geared toward understanding how spaceflight affects human physiology and psychology. "Every day we spend up here, we know a little more about how the human body behaves in space," Rubio explained. "We continue to do studies in the station that will help us when we continue exploring deeper and deeper into our solar system." Rubio is the first astronaut to participate in a study examining how exercising with limited gym equipment affects the human body. Recognizing that crew members traveling to the Moon and elsewhere will not have enough room in their spacecraft for a treadmill(跑步机), researchers are eager to determine whether other exercise plan could keep crews healthy on long missions. So rather than running on the space station's treadmill, Rubio exercised only on the space station's bicycle and weightlifting machine. He is also one of a handful of astronauts to help researchers test whether an enhanced ___ diet can help humans better adapt to life in space. For this study, Rubio met with a specialist to create a customized diet loaded with nutrients, with an emphasis on foods such as fruits, vegetables, and fish. Scientists will evaluate whether consuming this diet boosted his immunity and improved how his body functioned. For another experiment, Rubio helped nurture and monitor vegetables produced in the space station's Vegetable Production System, or Veggie. Future deep space missions will require astronauts to grow fresh food in space as an alternative to prepackaged food. This Veggie study evaluates regulations for growing produce in space, and whether plants grown in microgravity can help satisfy the dietary needs of astronauts on more distant spaceflight missions.
Mainstream science is finally recognizing the medicinal properties of ant honey, a substance native Australians have been using for centuries to treat colds and sore throats. According to a new study, this sweet substance carries strong antimicrobial(杀菌的) properties. Scientists from the University of Sydney's Carter Lab, led by Professor Dee Carter, studied the Australian honeypot ant. This ant species is found in desert areas, mainly in Western Australia and the Northern Territory. The honey these ants make isn't stored in cells in hives but inside other ants. Certain ants in their colonies are fed flower juice by other ants until their bellies swell to the size of grapes. Then when food is scarce, the honey-filled ants vomit up(吐出) their sweet liquid for the other ants to eat. "For our people, honey ants are more than just a food source. Digging for them is a very enjoyable way of life and a way of bringing the family together," says Danny Ulrich who operates honeypot ant tours in Western Australia. "Our people have been enjoying sweet honey ants for thousands of years. As for its medicinal use, we use it for sore throats and sometimes as a skin cream to help keep infections from getting worse." The study conducted by the Carter Lab marks the first time that ant honey has been investigated for its medicinal properties. The researchers found that ant honey possess "unique" antimicrobial activity against bacteria. They confirmed that its mechanism of action is different from that of Manuka honey, a well-established treatment for wounds and skin infections. Manuka honey is produced from the flowers of a native New Zealand tree. "Our research shows that honeypot ant honey possesses a distinctive effect that sets it apart from other types of honey," says Dr Kenya Fernandes from the Carter Lab team. "This discovery means that honeypot ant honey could contain compounds with substantial antimicrobial power, identifying these could provide us with starting points for developing new and different types of antibiotics."【缺少答案,请补充】
