Louise Blanchard Bethune showed early promise in math. But Louise did not go to school. Instead, her father taught her at home until she was 11 years old. She also discovered a skill for planning houses. It developed into a lifelong interest in architecture and a place in history as the first professional female architect in the United States.

    After graduating from high school in 1874, Louise traveled and studied. She hoped to prepare herself to attend the new architecture school at Cornell University. But then Buffalo's leading architectural firm of Richard A. Waite and F.W. Caulkins offered her a job. She knew that architects gained their training from practical experience, not from school. She took the job.

Louise worked there as an assistant, 10 hours a day for five years. She learned —-and mastered—-drawing and architectural design. She also met her husband, Robert A. Bethune. Their new firm, R.A. and LBethune, opened in October 1881.

    Bethune appeared to be the strength of the business. At the turn of the 20th century, the city of Buffalo was rapidly expanding to meet the demands of growing industry. The firm received tasks to build hundreds of structures throughout western New York. The firm designed lots of schools, apartment buildings, department stores, churches and factories.

    Bethune believed that being an architect meant being an artist, a scientist and a business person. She made a point of advocating for women in the profession. She became a member of the Western Association of Architects(WAA) in 1885. In 1888, she was the first woman to join the American Institute of Architects(AIA). Besides, Bethune took a firm stand on equal treatment for women architects. She insisted on equal pay for equal work.

    Bethune left almost no papers or letters, and few people recognize her name today. But her legacy remains in the foothold she established for women in the field of architecture. She started her own firm and enjoyed a successful career.

    What is eBay? The simple answer is that it is a global trading platform where nearly anyone can trade practically anything. People can sell and buy all kinds of products and goods, including cars, movies and DVDs. sporting goods, travel tickets, musical instrument clothes and shoes- the list goes on and on.

    The idea came from Peter Omidyar, who was born in Paris and move to Washington when he was still a child. At high school, he became very interested in computer monogramming and after graduating from Tuft University in 1988, he worked for the next few years as a computer engineer. In his free time he started eBay as a kind of hobby, at first offering the service free by word of mouth.By1996 there was so much traffic on the website that he had to upgrade (升级) and he began charging a fee to members Joined by a friend, Peter Skoll, and in 1998 by his capable CEO, Meg Whitman, he has never looked back. Even in the crashes of the late 1990s, eBay has gone from strength to strength. It is now one of the ten most visited online shopping websites on the internet.

    eBay sells connections, not goods, putting buyer and seller into contact with each other. All you have to do is take an e-photo, write a description fill out a sales form and you are in business; the world is your market place. Of course for each item (商品) sold eBay gets a percentage and that is a great deal of money. Every day there are more than sixteen million items listed on eBay and eighty percent of the items are sold……

    Electronic book publishing has many of the same risks and opportunities as electronic music publishing. By delivering text direct to the reader's computer screen, the e-book could cut down costs, and allow creators to deal directly with their audience, by passing (绕开) traditional publishers and traders. But it also raises the possibility of mass piracy (盗版). Phil Rance, founder and managing director of Online Originals, a London-based e-book publisher, sums it up, "No one wants Napster (在线音乐服务) to happen to books."

    Indeed, the most popular MP3may have put the frighteners on an industry that generally operates some way behind the "bleeding edge". The Meta Group, a leading US-based market researcher, says publishers are far too concerned about protecting their rights, "We believe all the recent legal control over Napster is like putting a finger in a river that is already overflowing. Publishers need to deal with reality and come up with new ways to develop wide electronic distribution, asking the question: How can we use the certainty of wide distribution to our advantage."

    At the moment, most publishers would like to limit the use of e-books to the person who bought them, or to the computer used to download them. If that can be done, e-books become just an extra income stream in a publishing industry that would continue to operate the way it does today, according to Terry Robinson, business manager for Adobe's e-paper group. "If you've cracked the digital rights aspect, you've cracked the market." He says.

    Robert Nichols, Books Director at BOL agrees, "Rights management is absolutely important. Publishers just say that 'until copyright is secure, we are not going to talk'."

    Loud cheers and applause broke out at NASA's Jet Propulsion Lab on Monday, November 25, 2018, as the unmanned lander, called Insight, touched down on Mars, after nearly seven years from design to launch to landing.

    The great arrival of the spacecraft­designed to listen for quakes and shakes as a way to discover the Red Planet's inner secrets, how it formed billions of years ago and, how other planets like Earth took shape­marked the eighth successful landing on Mars in Nasa's history.

    Minutes after InSight landed on the surface of Mars, the first image was sent back, showing a wide flat area as seen through a dirty camera.

    The touchdown came after a nearly seven-month, 300 million-mile travel from Earth to Mars, during which the InSight spacecraft had to slow down from a speed of more than 12,000 mph. The spacecraft's heat shelter helped the lander survive temperatures as high as 2,700℉.

    Each step along the way was watched nervously at JPL, with updates delayed by the eight-minute light travel time between Earth and Mars. Mission controllers hugged each other with joy when the signals were received. "We are proud of everything that has gone on today," they told us reporters.

    The first picture of the surface of Mars was sent back to Earth by one of the MarCO nanosatellites (马可纳米卫星) that accompanied InSight during its travel to Mars. The dust from the landing made the view unclear. Pictures from it were expected to be clearer once the dust settled and the lens cover (镜头盖) was removed.

    Hours later, InSight's batteries were charging as expected. The InSight team also passed on another picture, taken by a different camera that's fixed on the lander's robotic arm. The view is clearer, showing the robotic arm and the seismometer, which is used to discover the actual movement of the ground.

Sugar-free cookies, sugar-free candy, and diet soda – are these better for you? After sugar became a no-no in the nutrition and wellness world, sugar-free food and drinks acted as a replacement for once beloved sweet drinks and snacks. Being claimed to be ZERO sugar means the food and drinks are healthier, better for diabetics, and help you slim down… Right? Wrong. Sugar-free products aren't better for you. In fact, they are worse. For most sugar-free products, it means that artificial sweeteners (甜味剂) are used instead of real sugar. The problem is that these sweeteners do not come from natural sources and they can do you more harm than good.

Let's get into what these artificial sweeteners actually are. Sugar-free sugar sounds wrong because there is no such thing as sugar-free sugar. Some of these sugar-free alternatives even contain sugar and the ones that have chemicals your body often does not know how to process. Most artificial sweeteners are a lot sweeter than sugar so only a small quantity of them are needed. That's why they can market sugar-free alternatives as "low-calorie" or "no-calorie". It also means that you get no nutritional value from consuming them, which is why so many sugar-free replacements are classified as "non-nutritive". These artificial sweeteners tend to hide under some names. Actually, they are 200-600 times sweeter than sugar.

When you eat sweet stuff, your body continues to desire it and, even though your body cannot metabolize (代谢) these sugar-free alternatives, your brain does not know the difference. In turn sugar-free alternatives relate to weight gain and Type-2 diabetes. Besides, artificial sweeteners also damage your gut's ability to break down sugar which impacts everything you eat. In other words, your body doesn't know how to handle artificial sweeteners because they have nothing real to process.

Here is a good rule of thumb: stay away from artificial sweeteners and look for non-sugar, natural sweeteners like stevia (甜叶菊) or date sugar. In the war against artificial sweeteners and real sugar, both lose. Satisfy your sweet tooth with natural sugar that comes from fruits and stay away from products claimed to be sugar-free.
