      A new collectionof 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(海滩), 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 theEndurance, 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 be 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.

    If you will be cycling, you will need to know what these traffic signs and signals mean.

    A sign like this one means that there is a bike lane（道）. If there is a bike lane, you are required to use it. If there is not a bike lane, you should ride with traffic as far to the right side of the road as possible.

    When the signal light turns green, cars go. When you cross the street at a signal light, you should wait for the walk signal. Be sure to look carefully to the left, right and left again, before crossing the street.

    When the signal light turns yellow, car drivers should slow down and prepare to stop. You should not cross if the light is yellow. The light is about to turn red, and cars will enter the intersection(十字路口).

    This signal is the WALK sign. It has a picture of a person walking instead of using the word WALK.

    This signal is the DON'T WALK sign. It is part of the signal with the picture of a person walking. This is a picture of a red hand, meaning you should stop. You should wait to cross the street until the green picture of the person walking is showing.

    Car drivers and bikers must come to a complete stop at STOP signs.

    A yield sign means to slow down and be ready to stop. If there are pedestrians（行人）or vehicles in or nearing the intersection, you must stop. If there is no traffic in or nearing the intersection and it is safe, you may go through.

    This sign means you are coming to a crosswalk. Car drivers and bikers must stop to allow people in the crosswalk to cross the street.

    We often seek food after focused mental activity, like preparing for an exam. Researchers guess that too much thinking consumes a lot of energy from the brain. So the brain, sensing that it may soon require more calories to keep going, apparently leads to bodily hunger, and even though there has been little physical movement, we eat.

    The researchers note that tiring activity both increases the amount of blood sugar and lactate(乳酸盐)circulating in the blood and increases blood flow to the head.

    Because the brain uses sugar and lactate as fuel, researchers wondered if the increased flow of fuel—rich blood during exercise could feed a worn—out brain and reduce the urge to overeat.

    Thirty—eight healthy college students were invited to determine their fitness and metabolic(新陈代谢)rates and to report what their favorite pizza was. Afterward, they sat quietly for 35 minutes before being given as much of their favorite pizza as they wanted. At a later date, the volunteers returned and spent 20 minutes making selections from college and graduate-school entrance exams.

    Next, half the students sat quietly for 15 minutes, before being given pizza. The rest of the volunteers spent those 15 minutes doing intervals on a treadmill(跑步机)two minutes of hard running followed by about one minute of walking, repeated five times. These students were then allowed to gorge on pizza, too. But by and large, they did not overeat.

    When the researchers factored in(将……作为因素考虑)the calories burnt on running, they determined that those students actually consumed 200 fewer total calories after their brain workouts than the resting students.

    The researchers do not know if the runners consumed extra calories at dinner. They also cannot tell whether other types of exercise would have the same effect as running, although the researchers say they suspect that if an activity causes someone to break into a sweat, it should also increase blood sugar and lactate, feeding the brain and weakening hungers call.

    I never planned to be a teacher. I was headed for a law school, for a real career. Teaching was something to "get out of my system". I would teach a couple of years and then go to get a real job. After the first couple of years, I promised myself I would leave if I didn't love my job any more. Twenty-nine years later, that day still has not come.

    So, why do I stay? I stay because I laugh and learn every day. The children are funny, insightful, and honest. If my shoes don't match my outfit, they tell me. If my argument that Invisible Man is an important twentieth century classics doesn't convince them, they tell me.

    I stay because every single day is different. Some days, my lessons are great, and I have classes of students who are engaged in reading, writing and thinking. Some days, my lessons fall flat, and I realize that I need to start from scratch — even after 29 years.

    I stay because I love to see the children realize that they have learned something — whether it's how to craft an argumentative thesis sentence or how to understand the effect of repetition in The Declaration of Independence. I love to see the children write well; I love the feeling of reading a well-argued essay, and I love smiling as I write a final "Awesome job!" on a paper on which a student has worked hard.

    I stay because what I've learned in 29 years is that I do have a "real" job — the most real job there is. It's the one that leads to other jobs, that helps to create good thinkers who go on to be productive in our society, and that supports our community as it grows and times change. My job is among the ones that matter most.

    I don't think I can recall a time when I wasn't aware of the beauty of the ocean. Growing up in Australia, I had the good fortune of having the sea at my side. The first time I went to Halfmoon Bay, I suddenly had the feeling of not being able to feel the ground with my feet anymore.

    For my 10th birthday, my sister and I were taken out to the Great Barrier Reef. There were fish in different colors, caves and layers of coral. They made such an impression on me. When I learned that only 1 percent of Australian's Coral Sea was protected, I was shocked. Australian marine life is particularly important because the reefs have more marine species than any other country on earth. But sadly, only 45 percent of the world's reefs are considered healthy.

    This statistic is depressing, so it's important for us to do everything to protect them. The hope that the Coral Sea remains a complete eco-system has led me to take action. I've become involved with the Protect Our Coral Sea activity, which aims to create the largest marine park in the world. It would serve as a place where the ocean's species will all have a safe place forever.

    Together, Angus and I created a little video and we hope it will inspire people to be a part of the movement. Angus also shares many beautiful childhood memories of the ocean as a young boy, who grew up sailing, admiring the beauty of the ocean, and trying to find the secrets of ocean species.
