We all know that the cost of heating our homes will continue to be a significant burden on the family budget. Now millions of people are saving on their heating bills with the EP portable heater. With over one million satisfied customers around the world, the new EP heats better and faster, saves more on heating bills, and runs almost silent.

    The EP has no exposed heating parts that can cause a fire. The outside of the EP only gets warm to the touch so that it will not burn children or pets.

    The EP will not reduce oxygen in the room. With other heaters, you'll notice that you get sleepy when the heat comes on because they are burning up oxygen.

    The advanced EP also heats the room evenly, wall to wall and floor to ceiling. It comfortably covers an area up to 350 square feet. Other heaters heat rooms unevenly with most of the heat concentrated to the center of the room. And they only heat an area a few feet around the heater. With the EP, the temperature will not vary in any part of the room.

    The EP comes with a 3-year warranty (保修) and a 60-day, no questions asked, satisfaction guarantee. If you are not totally satisfied, return it at our expense and your money will be given back to you.

    Now we have a special offer for 10 days, during which you can enjoy a half price discount and a free delivery. If you order after that, we reserve the right to either accept or reject order requests at the discounted price.

Great women

    When it comes to changing the world, these women have invented, researched and collected their way to a place in scientific history.

    Hedy Lamarr

    More widely known as a Hollywood star during the 1930s and 1940s, Hedy Lamarr（1914－2000）was much more than a pretty face. After her home country Austria was taken over by the Nazi, highly intelligent and fearless, Lamarr worked with scientist and inventor George Antheil to develop a secret communication system. Without her work, wireless（无线的）technology as we know it today would not exist. Today she is considered as the mother of WiFi.

    Ameenah Gurib-Fakim

    Ameenah Gurib-Fakim was born in 1959 in Mauritius, the country for which she now serves as the first woman president. She is a scientist who has spent many hours researching the local plants of Mauritius and their values as medicine. She has held many high positions in the fields of both politics and science and was awarded（授予）the 2007 UNESCO Award for Women in Science.

    Mae C. Jemison

    On June 4,1987, Mae C. Jemison became the first African-American woman to enter the space program. On September 12,1992, she joined several other astronauts on the Endeavour, becoming the first African-American woman in space. Born in Decatur, Alabama in 1956 and raised mostly in Chicago, Jemison holds many awards and degrees, As a child, Jemison spent a lot of time in her school library ,reading especially books space.

    Every morning, Claire Buckley was rushing to catch the bus. She left for Barrington High School in Illinois at 6 a.m.. She would come home very tired. Kids like Clair Buckley are suffering from lack of sleep. Less sleep causes stress. Stress is when someone is under a lot of pressure. Not sleeping is just one reason experts say more students feel nervous at school. Local schools in Illinois are trying new way to fix it, wishing kids to feel healthy and happy.

    Some schools are changing their calendar(日历). They are giving tests before school breaks. This way students do not have to worry about studying when they are away from school. Some places changed their after-school activities. Coaches can only organize one practice a day. Teachers now cannot give homework during certain holiday breaks. But some kids want very much to do well on tests. They think it will get them into good colleges, which causes them stress.

    A study showed different things stress different students out. Students were not able to see their grades online. This stress some students. Other students said seeing their grades made them more stressed. Some say parents are causing stress. They try to make their kids do not fail. They want their kids to not be disappointed. Children need to fail, says Dr. Carol Weitzman, a doctor for children. When kids learn to fail, they learn to get back on their feet. This is an important skills for life, she says.

    Various ways are adopted to reduce stress. Students at John Hersey High School drop by Dr. Brigette Muck's office looking for stress relief. She has aromatherapy (芳香疗法) products. The smells make you fell relaxed. She also has stress balls and coloring books to help work out nervous feelings. Other schools use mentorship(导师制) program, sports and yoga classes to help students feel better.

    Car companies are developing vehicles that will plug into electric sockets(电源插座), just like many laptops, digital cameras, cell phones and MP4 do. Called "plug-in vehicles", these cars will get most of their power from electricity. Their drivers won't have to stop at gas stations as often as usual.

    The technology is more than just cool. In our car-filled world, plug-in vehicles could reduce the amount of gas we use, which keeps rising in cost now and then. Besides, driving around in these vehicles may even help the environment. Gas-burning cars produce a lot of greenhouse gas, which causes global warming.

    The first company-produced plug-in vehicles could hit the roads by 2020. But engineers still have a lot of work to do to make the technology practical and inexpensive.

    Batteries are the biggest challenge. In the plug-in-vehicle world, Li-ion(锂离子)batteries are getting the most attention. These batteries can store a large amount of energy in a small package, and they last a longer time between charges. Li-ion batteries can fit laptops, cell phones, heart instruments and other similar pocket ones.

    But because cars are so big and heavy, it would still require a suitcase-sized Li-ion batteries to power about 12km of driving. What's more, the batteries are much expensive.

    "A car filled with batteries could go a long distance," says Ted Bohn, an electrical engineer in Chicago. "But it couldn't pull any people, and it would cost $100,000." So researchers need to work out how to make batteries smaller and cheaper, among other questions.

    "The answers don't exist yet." Bohn says, "As a kid, I thought someone someplace knows the answer to everything. All of these questions haven't been decided. But that's what engineering is about--making a guess, running tests and getting fine results."

If you are a psychology enthusiast, you have probably heard of the famous marshmallow test （棉花糖实验）. In this task, kids are given a marshmallow, and are told that they can eat that marshmallow now, or wait a little while, and have two marshmallows instead. Some kids eat the marshmallow immediately, but most try their best to wait for two. 

When the researchers followed up with those kids later in life, children who waited longer had better life outcomes: more academic success, better social behavior, and even markers of better health. They believe those children who keep waiting are the ones with the most self-control-a key factor in success, and that's why they are so successful later. 

But what if the behavior in the marshmallow test has more to do with cultural norms than self-control?

A 2022 study tested the idea that children may decide how long to wait for rewards based on what they are accustomed to waiting for in their culture. For example, in the United States, there is no widespread mealtime custom of waiting until everyone is served. In Japan, however, there is. 

Because of this difference in norms, the researchers hypothesized that Japanese children would wait longer in the marshmallow test than the American children. This is exactly what they found later in experiments. 

But this isn't conclusive evidence; after all, maybe Japanese children actually have better self-control, or maybe they differ from American children in other ways that could explain the result. 

In the U. S. , gifts are usually given on special occasions and children usually have to wait before they can unwrap their presents. In Japan, however, gift-giving happens more often, and children usually open presents immediately. 

Given these cultural differences, scientists expected that if they ran the test with gifts instead of marshmallows, American kids would wait longer. Once again, their hypothesis was correct. 

This is a powerful result because it demonstrates the importance of culture and habit in shaping behavior. If a child waits only few minutes before giving up on two marshmallows but much longer to unwrap a gift, can we really say that child lacks self-control? I don't think so. I think it just means that they are adjusting well to their social settings. 

It's no secret that reading good news feels a lot better than reading bad news. Like, would you rather bite into a lemon, or sip on a fresh glass of lemonade?
