A new collection of photos brings an unsuccessful Antarctic voyage back to life.

Frank Hurley's pictures would be outstanding—undoubtedly first-rate photo journalism—if they had been made last week. In fact, they were shot from 1914 through 1916, most of them after a disastrous shipwreck(海难), by a cameraman who had no reasonable expectation of survival. Many of the images were stored in an ice chest, under freezing water, in the damaged wooden ship.

    The ship was the Endurance, a small, tight, Norwegian-built three-master that was intended to take Sir Ernest Shackleton and a small crew of seamen and scientists, 27 men in all, to the southernmost shore of Antarctica's Weddell Sea. From that point Shackleton wanted to force a passage by dog sled(雪橇) across the continent. The journey was intended to achieve more than what Captain Robert Falcon Scott had done. Captain Scott had reached the South Pole early in 1912 but had died with his four companions on the march back.

    As writer Caroline Alexander makes clear in her forceful and well-researched story The Endurance, adventuring was even then a thoroughly commercial effort. Scott's last journey, completed as he lay in a tent dying of cold and hunger, caught the world's imagination, and a film made in his honor drew crowds. Shackleton, a onetime British merchant-navy officer who had got to within 100 miles of the South Pole in 1908, started a business before his 1914 voyage to make money from movie and still photography. Frank Hurley, a confident and gifted Australian photographer who knew the Antarctic, was hired to make the images, most of which have never before been published.

    Hummingbirds(蜂鸟) are one of nature's most energetic fliers and the only birds to hover(盘旋) in the air by relying on their strength alone.

    Now scientists have found that it is the ratio(比值) of the bird's wing length to its width that makes them so efficient. The discovery is helping experts compete with 42 million years of natural selection to build helicopters that are increasingly efficient.

    David Lentink, an assistant professor at Stanford University in California, tested wings from 12 different species of hummingbirds, which he sourced from museums. He placed them on a machine used to test the aerodynamics(气力学) of the helicopter blades(桨叶). Professor Lentink's team used the same machine to test the blades from an advanced micro-helicopter used by the UK's army. They found that the micro-helicopter's blades are as efficient at hovering as the average hummingbirds.

    But while the micro-helicopter's blades kept pace with the average hummingbird wings, they could not keep up with the most efficient hummingbird's wing. The wings of Anna's hummingbird were found to be about 27 percent more efficient than the man-made micro- helicopter's blades.

    While Professor Lentink wasn't surprised at nature's superiority, he said that helicopter blades have come a long way. “The technology is at the level of an average hummingbird,” he said. “A helicopter is really the most efficient hovering device that we can build. The best hummingbirds are still better, but I think it's amazing that we're getting closer. It's not easy to match their performance, but if we build better wings with better shapes, we might match hummingbirds.”

    Professor Lentink said that we don't know how hummingbirds maintain their flight in a strong wind, how they navigate(确定方向) through branches, or how they change direction so quickly. He thinks that great steps could be made by studying wing aspect ratios-the ratio of wing length to wing width. Understanding these abilities and characteristics could be a benefit for robotics and will be the focus of future experiments.

BLOOD DRIVE ＆ MARROW（骨髓）REGISTRATION

    "These patients deserve a chance at a normal, happy future and they rely on the kindness of the strangers to make that happen.

    — Daisy, Isabelle's Mother

    Isabelle is the daughter of Daisy and Saman Mirzaei. In January 2008 Isabelle was diagnosed（诊断）with a genetic blood disorder，beta thalassemia. Isabelle's body is unable to produce healthy red blood cells. As a result, Isabelle has been receiving blood transfusions (输血) every 4-6weeks since she was 11 months old. A lifetime of regular transfusions can lead to serious medical problems. Her only chance at a normal, healthy life is to have a marrow transplant.  Isabelle is an only child, so doctors have started a search for an unrelated marrow donor through The Match Registry. The Mirzaei family asks that you consider helping patients like Isabelle by registering to be a marrow donor and give the gift of life, the gift of blood.

    In my life, my grandfather has influenced me a lot. Ever since I was a little kid, I have always loved sports, especially football. My grandfather also enjoys sports and really loves football. He received a couple of awards in football matches. Through my three years so far in high school, my grandfather has helped me become a better player.

    Another reason why I admire my grandfather so much is because of his strong work ethic(道德). Ever since I was a little boy, my grandfather has taught me and shown me what good work ethic means. He is a good example. When he was a young man, his family owned a small store. He often helped his father run the store. He has also done several jobs in his life. He owned his own store when my mother was a young girl; he helped on a farm; he then had his own painting business. Now he is working at a Wal-Mart.

    Responsibility(责任) is something that I have struggled with in the past. My grandfather, on the other hand, is a very responsible person. That's why I am very responsible now, because of him. When he was in school, he was almost a straight A student. I, on the other hand, don't do so well. One day he had a talk with me about being more responsible. He helped me in school and made me realize how important grades are. Now I get almost As and Bs.

    Now you can see why I admire and respect my grandfather as much as I do. He is the best role model I have, and I will always look up to him.

    In October 2013, Davion Only made an appeal on the Internet. He had learned that his biological mother had died not long before. "My name is Davion and I've been in foster care (寄养照管) since I was born," he said, "but I'm not giving up hope. "

    The heartbreaking appeal spread quickly, and Only's foster agency received calls from more than 10,000 people. Only ended up travelling to Ohio to live with a family. But after Only got into a physical fight with one of his elder would-be brothers, the family changed their minds.

     Back in Florida, Only passed through four different temporary homes over the following year, until he called Connie Going, his adoption case worker, to make a special request. Only had known Going for nearly ten years, and had asked every year if she would adopt him, but she always hesitated. "I always believed there was a better family than us out there," Going said in an interview. But last July, when Only called and asked again if she might adopt him, Going said something felt different. "When he asked me, my heart felt this ache and I just knew he was my son," she said.

     So Going, 52, invited Only to start spending time with the rest of her family-her two daughters, Sydney, 21, and Carly 17, and a son Taylor, 14, who she also adopted out of foster care. Eventually, after seeing how well the arrangement was working, Going, who had rented a bigger home, started adopting Only. Only moved in with her family last December. He officially joined Going's family on April 22, 2015 when the adoption papers went through.

    "Today, I feel blessed and honored to have been chosen to be the parent of all my children," Going said.
