A new American weather satellite could save more lives by better predicting extreme weather conditions. It will be in orbit(轨道）some 36,000 kilometers above Earth's surface. The National Oceanic and Atmospheric Administration, also known as NOAA, has been working with the National Aeronautics and Space Administration (NASA) on the project.

    NOAA officials are calling the new satellite GOES-R. That is short for a much longer name—the Geostationary Operational Environmental Satellite-R Series. NOAA said GOES-R could improve the nation's ability to observe weather conditions and make weather predictions. It said the satellite's operation would lead to more exact and timely weather forecasts watches and warnings.

    The government agency said the satellite will require testing of its six instruments and will be ready to work “within a year."

    "The next generation of weather satellites is finally here." said NOAA Administrator Kathryn Sullivan. She described GOES-R as one of the most complicated Earth-observing machines ever created. Sullivan said its instruments will be able to study Earth five times faster and with four times more detail than any other NOAA satellite currently in operation. She believes this will make the United States an even stronger, more “Weather-Ready" nation.

    A NOAA statement said the greater detail will help improve the agency's study of ocean storms, as well as “the prediction and warnings of severe weather. "In addition, GOES-R will be able to provide improved rainfall estimates (预计), which will lead to more timely and detailed flood warning. The statement also said that GOES-R will give better estimates of wind strength, as well as better measurement of fog, ice or lightning strikes.

    Craig Fugate serves as administrator of the Federal Emergency Management Agency. He says that the GOES-R satellite will improve the ability of people and organizations across America to prepare for, and react to, weather-related disasters.

    There are many reasons why people can't get a good night's sleep and as with any other health conditions, things are not likely to improve until you find a way to break the cycle.

    These are some of the main factors that need to be addressed.

    Worry and stress

    We have all been kept awake by many factors that cause worry and stress in our lives. Money problems, relationship issues and work stresses can have you sitting up all night. A useful habit is to download your thoughts at the end of the day. Keep a pen and paper next to your bed and before you go to sleep, write down your thought and worries, create a to-do list for the following day or set down solutions and ideas that relate to work.

    Diet and eating patterns

    What and when you eat can have a major impact on your ability to sleep. Eating too late or indulging in a rich or spicy meal can keep you awake. These foods take a long while to digest and the after effects of indigestion and heartburn are not going to set you up well for a good quality sleep.

    A research suggests that both calcium and magnesium may be linked to poor sleep. Even low intakes of magnesium found in green vegetables, beans, nuts and seeds have been shown to make it harder to stay asleep. Calcium is found in dairy foods, soybeans and green vegetables and low levels have also been shown to make it more difficult to nod off.

    Alcohol and caffeine

    Tea, coffee and energy drinks contain caffeine that helps to stimulate the nervous system and make you more alert, which is great if you need a pick-me-up. Dosing up on caffeine during the day can affect your ability to sleep later on in the evening. Try limiting your intake of caffeine to the morning and switch to decaffeinated options such as herbal teas. Alcohol is a double-edged sword when it comes to sleep. While a little may help to induce slumber, even in small amounts it can cause fragmented sleep patterns.

    Bedroom environment

    “Your bedroom should be dark once the lights are switched off because melatonin, a sleep-regulating hormone, is very light-sensitive. Maintaining the right temperature can also help with sleep as a room that is too hot may prevent your core temperature from going down, which is essential for switching on the sleep mechanism within the body.

    Last week my youngest son and I visited my father at his new home in Tucson, Arizona. He moved there a few years ago, and I was eager to see his new place and meet his friends.

    My earliest memories of my father are of a tall, handsome, successful man devoted to his work and family but uncomfortable with his children. As a child I loved him, as a school girl and young adult I feared him and felt bad about him. He seemed unhappy with me unless I got straight A's and unhappy with my boyfriends if their fathers were not as "successful" as he was. Whenever I went out with him on weekends, I used to struggle to think up things to say, feeling on guard.

    On the first day of my visit, we went out with one of my father's friends for lunch at an outdoor cafe. We walked along that afternoon, did some shopping, ate at the street table, and laughed over my son's funny facial expressions. Gone was my father's critical（挑剔的）air and strict rules. Who was this person I knew as my father, who seemed so friendly and interesting to be around? What had held him back before?

    The next day my dad pulled out his childhood pictures and told me quite a few stories about his own childhood. Although our times together became easier over the years, I never felt closer to him at that moment. After so many years, I'm at last seeing another side of my father. And in so doing, I'm delighted with my new friend. My dad, in his new home in Arizona, is back to me from where he is.

    Last night Mr. and Mrs. Rojas stayed home. It was cold and rainy and they didn't want to go out in the bad weather. Mrs. Rojas made some popcorn and ice tea. At 8:00, Mr. and Mrs. Rojas went into the living room, sat on the sofa and began the movie and ate and drank. At 8:15, Mr. and Mrs. Rojas realized they already watched the movie last year and they didn't want to watch it again.

    “Now what?” asked Mr. Rojas. “Let's play cards!” answered Mrs. Rojas. At 8:30 Mr. and Mrs. Rojas started to play cards. They were playing for about 10 minutes when Mr. Rojas looked out the window. The rain changed to snow and the trees were covered in beautiful white snow. “I'm happy we stayed home tonight. It looks beautiful outside but this weather is very dangerous to drive in.” said Mr. Rojas. “You're right,” said Mrs. Rojas, “but I'm bored. Let's play some music and dance.”

    Mr. Rojas was surprised. “Dance? But I really don't ….”

    “Oh come on!” Mrs. Rojas insisted. She put on a romantic CD and they both started to dance. They were dancing for about 1 minute when suddenly the music stopped and the lights went out.  Mrs. Rojas laughed. “We're just not very lucky tonight, are we?” she said. Mr. Rojas said, “Of course we're lucky! We are together!” He kissed her and continued to dance with her, in the dark and without music.

    Humans' invention of zero was vital for modern mathematics and science, but we're not the only species to consider “nothing” a number. Parrots and monkeys understand the concept of zero, and now bees have joined the club, too.

    Honey bees are known to have some numerical skills such as the ability to count to four, which may come in handy when keeping track of landmarks in their environment. To see whether these abilities extended to understanding zero, researchers trained 10 bees to identify the smaller of two numbers. Across a series of trials, they showed the insects two different pictures displaying a few black shapes on a white background. If the bees flew to the picture with the smaller number of shapes, they were given delicious sugar water, but if they flew toward the larger number, they were punished with bitter-tasting food.

    Once the bees had learned to consistently make the correct choice, the researchers gave them a new choice: a white background containing no shapes at all. Even though the bees had never seen an empty picture before, 64% of the time they chose it rather than a picture containing two or three shapes, the authors report today in Science. This suggests that the insects understood that “zero” is less than two or three. And they weren't just going for the empty picture because it was new and interesting. Another group of bees trained to always choose the larger number tended to pick the nonzero image in this test.

    In further experiments, the researchers showed that bees' understanding of zero was even more complex: for example, they were able to distinguish between one and zero-a challenge even for some other members of the zero club. Advanced numerical abilities like this could give animals an evolutionary advantage, helping them keep track of predators（捕食者）and food sources. And if an insect can display such a thorough grasp of the number zero, write the researchers, then this ability may be more common in the animal kingdom than we think.

When it comes to commemorating a child's first year of life, the traditional approach often involves presenting an exquisitely adorned confectionery masterpiece to the young celebrant. By simply setting this visually striking sugar creation before the infant and activating the recording devices, one can capture the ensuing delightfully chaotic scene, replete with smiles and smears of frosting.

However, this will not be the method I choose to honor my daughter's initial 12 months of existence—not because the sweet treat will be absent, but because my spouse and I have resolved to abstain from sharing her images on social platforms for an entire year, and we are determined to maintain this practice for the foreseeable future.

I understand that I am part of a select few. Research indicates that approximately seventy-five percent of parents habitually upload photographs of their offspring to the internet. Pixsy, a platform that assists photographers in identifying unauthorized usage of their work, discovered that parents in the age bracket of 20 to 25 are twice as likely as their older counterparts to disseminate images of their little ones on social media platforms.

Yet, I am not the only one who feels this way. A woman instrumental in the creation of Big Little Feelings—an Instagram account with 2.8 million followers that provides guidance to new mothers—recently decided to remove all the pictures she had previously posted of her children.

The discourse surrounding "sharenthood," or the inclination of parents to broadcast their children's lives online, has been fervently ongoing for some time. The everyday choices made by parents have a significant, yet often undervalued, impact on the digital legacy of young individuals and their subsequent life trajectory.

Technological advancements have introduced fresh challenges for parents. The latest development in artificial intelligence is the emergence of image-generating tools. By inputting a series of descriptive terms into a text field, AI can generate a visual representation of the described subject. The datasets for these AI-driven generative systems are frequently sourced from the open internet.

While it is improbable that my daughter's Instagram photos would be processed through such an AI assembly line, resulting in her likeness appearing in someone's creative AI-generated artwork, once images are disseminated on the web, they can be exceedingly difficult to eradicate completely.

I do share photographs with friends and family via secure, private messaging applications. However, these closed networks are fundamentally distinct from public postings on the open internet.
