Elizabeth Blackwell was the first woman doctor in the United States. Her success opened the way for other women who wanted to do more than nursing. She was born in England in 1821 and her family moved to America when she was eleven years old.

    The Blackwell girls received the same education as their brothers. This was most unusual in those days. Their father died young and they had very little money to live on. Elizabeth and her sisters taught at school. Then a woman dying of cancer urged Elizabeth to study medicine, saying that a woman doctor would have saved her from her worst sufferings. Nearly everyone said a girl should not go to medical school, but she managed to enter Geneva College in New York State. She graduated in 1849 at the head of her class and received the first medical degree ever given to a woman.

    Next, Dr. Blackwell went to Paris. Her only chance of training was in a hospital where women came to have their babies. Four months later, while she was working in the French hospital, her left eye became dangerously infected (感染). She lost the eye. She was very disappointed. But she was soon back at work again, this time in London, England. There she met many famous scientists.

    In 1859, Elizabeth Blackwell was officially recognized as a doctor in Great Britain — the first woman to be honored. She was the inspiration of Elizabeth Garrett, who began the women's medical movement in England. Florence Nightingale, founder of the practice of nursing by women, was another of her friends.

    Dr. Blackwell died in 1910 at the age of 89.

    What is it?

    KindSpring has created a series of 21-Day Challenges designed to help individuals and groups grow in values that help create positive change. Regardless of profession, age, culture or geography, when we try to cultivate(培养) certain values we create a ripple effect(连锁反应) that has the power to transform our lives and the world for the better. When we practice these values together over and over again, our efforts encourage and strengthen each other in remarkable ways. Each of our 21-Day Challenges focuses on a specific value — from kindness to mindfulness. Click here for more information.

    How does it work?

    A small daily commitment + a daily prompt(提示)+ a process for communication. Each 21-Day Challenge invites participants to carry out one small daily action related to the main theme. Every day for three weeks a unique idea is emailed out that serves as a prompt. Participants are encouraged to carry out the act and share stories of their experiences in both online and offline spaces. You can sign up to participate as an individual or you can “host” a challenge for a group you belong to. The challenges were developed for workplace, school/college and family environments, but are broadly usable. Any group is more than welcome to take them on. At the end of 21 days, you may continue the practice with your group, take on a new challenge, or even design your own. There is no charge for any of our services. All the challenges are offered as a gift. Five steps to host a challenge.

    Why should we do it?

    The 21-Day Challenges are all designed to fit the pace of modern day life. They are not very time-consuming（耗时的）, and in most cases demand less than five minutes a day. Twenty-one days certainly can't change everything, but it can begin a new way of being. You are invited to bring these practices to your company, school, community center, or family. Get started with joining a challenge or hosting one here. Let us know if you have questions—we're delighted to help any way we can!

    Saber Miresmailli was on vacation in London when, caught in a bit of traffic on London Bridge, he decided to take a photo of Tower Bridge.

    “I noticed the couple,” he said. “At that moment, I did not see anyone from the wedding party or a photographer with the couple, so I took several pictures. Usually, my pictures are not very good given the fact that I don't use flash and I don't stop to compose (构图)-so when we get back after two weeks, I was very surprised to find this one turned out so well.”

    Miresmailli said, “I thought to myself, if it was me getting married, I would have wanted the picture.” So he posted the photo on Facebook and attached a few friends with the hope of finding the couple and passing them the picture. What happened next, he said, “was crazy”. “I received more than 2,000 requests from perfect strangers and lots of positive and negative emails.” Until this afternoon, almost 230,000 people had shared his Facebook post on the photo.

There's also been an uncertain identification of the couple. It's likely that their names are Laura and James. “If it's the right couple,” Miresmailli said, “they are on their honeymoon in Bali and have no idea about the photo. I believe they will be shocked to find out about their fame.”

    Miresmailli said he's been drowned by the interest in the photo. “I just want to give them their picture and go back to work and tend my tomatoes,” he said.

    A group of scientists is gathering today in the U. K. to discuss a thick piece of ice that's cracking in Antarctica, which is of the size of Delaware.

    The ice shelf is called Larsen C, and it now has a 90-mile crack running through it. The big rift (裂缝) is slicing the ice shelf from top to bottom. But this is not just another sad climate change story. It's more complicated. "A lot of things are going on deep inside the ice," says Adrian Luckman, a glaciologist.

    Luckman says climate change is certainly influencing this region. Larsen C used to have two neighbors to the north, Larsen A and Larsen B. As the air and water warmed, those ice shelves started melting and then disappeared in 1995 and 2002. But the crack in Larsen C seems to have happened on its own, for different reasons.

    Larsen C has many cracks. All ice shelves do. This particular crack has been around since at least the 1960s. The unusual part is that in 2014, this crack — and only this crack — started growing quickly. Why?

    "Well, that is a little bit of a mystery and that's why it drew itself to our attention," says Luckman. One puzzling aspect is how it managed to cut through areas of softer ice that bind (连接) the ice from neighboring glaciers into one giant sheet. Starting in 2014, that soft ice did very little to slow down this rift.

    Scientists are split on how important this crack is for the stability of the whole ice shelf. Some say if this giant section breaks off, it won't make a difference. Others disagree.

    "Ice shelves are the gates of Antarctica in a way, and the gatekeepers of Antarctica. The ice shelves are already floating, so if they fall apart it does not immediately affect sea levels. It's what they hold back -water from all the inland glaciers — that could be problematic. If all the water packed in those glaciers made their way to the sea, it could significantly raise global sea levels," says Ala Khazendar, a geophysicist.

    Mill 180 Park is truly a park for the 2lst century, designed to copy all of the great urban parks -Central Park in New York City, Hyde Park in London and Ueno Park in Tokyo. Through the use of computerized sound and some other modern systems, we've brought the outside in, surrounding our visitors with green space and a remarkable sense of the natural world.

    We spent a lot of time trying to learn why these parks are so beloved, what makes them work so well for their sponsors, and how they provide a place of rest for so many.

Students from Oceanside High School in Rockland will be able to sleep in a little longer from this autumn.

Regional School Unit 13 Superintendent (负责人) Lew Collins said during the school's Thursday night meeting that the schedule (时间表) for the schools will be changed. Oceanside East and West will start a half hour later, at 8 a.m. for their new school year.

Research has shown that teenagers' brains are often not fully awake at 6:30 a.m. Collins said the schedule, which is used to get students to school for classes that begin at 7:30 a.m., calls for some to get on buses before 6 a.m. to get to school on time. Teachers are having meetings at 6:40 a.m., which is too early, he thinks.

Collins visited the high schools in Rockland and asked students when they would like classes to begin. Most of them said 8:00 a.m. "I was surprised. I thought they would have said 9:00 or 10:00," he said.

The National Sleep Foundation says on its website that teenagers' biological clocks (生物钟) are designed to stay up later and get up later. The Foundation called for schools to change their schedules, which means a later start as well for elementary students (小学生).

We do not have enough buses to run, since all the high school and elementary school buses run almost at the same time, Collins said. He suggested, "We should buy six more buses and get six more drivers to keep the new schedule working."

Elementary school classes in Rockland now start at 8:30 a.m., but will be moved to 8:45 a.m., starting in the autumn. "I know this is a problem for working parents, but we will see what we can come up with," said Jane Brown, a teacher at Bardonia Elementary School. "Anyway, I believe if students get more sleep they'll be more ready to learn when classes start," she added.
