Astronauts aboard the International Space Station (ISS) recently tested an oven they used to bake five chocolate chip cookies. We now know the results of that experiment: the cookies took a lot longer to bake in space than on Earth. The cookies that came out best required two hours of baking time inside the International Space Station. The baking time for cookies on Earth is generally only about 20 minutes.
The cookies returned to Earth earlier this month aboard a SpaceX-built spacecraft that splashed down in the Pacific Ocean. The cookies are the first food baked in space from raw food materials. They remain frozen in a laboratory in Houston, Texas. The American company Nanoracks designed and built the cookie oven. Hilton DoubleTree hotels supplied the cookie dough.
The makers of the oven did expect some difference in the baking time in space, but they were surprised that that difference was so large. "There's still a lot to look into to figure out really what's driving that difference, but definitely a cool result," said Mary Murphy. She is with the company Nanoracks, which is based in Texas. Murphy said the baking results will continue to be examined in order to better understand why space baking took so much longer. In addition, researchers will study the effectiveness of the baking tray, which was designed to work in microgravity conditions.
The five chocolate chip cookies were frozen when they were sent to space. Each had to be baked separately in the oven. Italian astronaut Luca Parmitano took charge of the baking experiment in December. He reported that the first cookie stayed in the oven for 25 minutes at 149 degrees Celsius. When it came out of the oven, it was seriously under-baked. For the next two cookies, Parmitano more than doubled the baking time. Those cookies came out better, but were still under-baked. The fourth cookie stayed in the oven for two hours, after which Parmitano was able to report success. "I can't tell you whether it's cooked all the way or not, but it certainly doesn't look like cookie dough anymore," he reported to controllers back on Earth. For the fifth cookie, Parmitano turned the oven temperature up to 163 degrees Celsius and baked it for 130 minutes. This time, he reported the best baking results.
No one has tasted the space-traveling cookies just yet. Organizers of the experiment say additional testing will need be carried out to determine whether they are safe to eat.

A decade ago, colored lights danced around the living room on New Year's Eve and happy music was played. Upstairs, the children were asleep. But I wasn't feeling happy. In mid-December, my husband and I had been informed that he had cancer and that he was going to die. He had less than a year left, the doctors said.
In the years since that painful season, I have come to look back upon New Year's Eve as an ending and a beginning. New Year's Eve brings a halt to the endless commitments that fill our daily lives and a chance to reflect.
New Year's Eve is full of possibility and anticipation. What will be the surprising experiences and delightful successes in the coming year? But also, what disappointments are waiting for us in the next twelve months?
In many ways, New Year's Eve and the days that surround it are a line between past and future. That line is made up of a series of moments of transition that take us out of the old and into the new. Transition can be challenging for many of us. It's about letting go of the familiar and diving headlong （迅猛地） into the unfamiliar.
Just as, back then, I had to face letting go of the life I had led with my beloved husband and stepping into a new world as a widowed （丧偶的） mom. I find that each year I have to step out of the version of me that suited the year that is ending and ease into the version of me who will rise to the goals I am holding for myself for the year ahead.
Last year at this time, I sat in a chair in southern France and drank in the stillness and beauty of the countryside around me. The three children and I had brought into this world talked and laughed around the table beside me as we enjoyed a lunch of bread and cheese.
I was filled with a sense of joy and I had a glowing heart that was full of hope. It was another ending and another beginning. May we all transition into the best of what lies ahead. May we all find happiness this holiday season.

On the afternoon of May 25th, a charity sale held by the Students’ Union on our school playground. In order to keep everything organized, we made fully preparations. Before the sale, from the student we collected various used books and second-hand goods which were still in a good condition. Then we classify them. When the day came, students and teachers both came and took an active part in it. In the end of the activity, we raised 5000 yuan in total. All the money which we raised will be sent to the students from poor families in our school to help finishing their studies. It’s such meaningful an activity that students are all looking forward to the next charity sale.
