A warm drink of milk before bed has long been the best choice for those wanting a good night's sleep. But now a study has found it really does help people nod off（打瞌睡）—if it is milked from a cow at night.

    Researchers have discovered that “night milk” contains more melatonin(褪黑激素), which has been proven to help people feel sleepy and reduce anxiety（焦虑）.The study, by researchers from Seoul, South Korea, involved mice being fed with dried milk powder（奶粉） made from cows milked both during the day and at night. Those given night milk, which contained 10 times the amount of melatonin, were less active and less anxious than those fed with the milk collected during daytime, according to the study published in The Journal of Medicinal Food.

    Night milk quickened the start of sleep and caused the mice to sleep longer.

    While the effect of cow milk harvested at different time has not been tested on humans up to now, taking melatonin drugs has been suggested to those who have trouble falling asleep at night.

    Previous （以前的）studies have also showed that milk can be excellent for helping sleep because of the calcium content, which helps people to relax.

    As Simon Kindleysides, 34, took his first step in the London Marathon in April, he felt as if magic was in the air.

    "As we were walking toward the first mile, we actually started joining all the runners," he said. "Everyone was on the streets, cheering, and that was a magical moment." As time went on, the crowds and other racers spread around. Kindleysides and his team of eight supporters continued walking.

    Kindleysides, who is paralyzed(瘫痪的)from the waist down and typically uses a wheelchair, was equipped with an exoskeleton(体外骨骼)to help him walk. His supporters walked with him to change the batteries in his exoskeleton so he could keep moving.

    In 2013, Kindleysides was diagnosed with a brain tumor (肿瘤) that was growing in a way that pressed on certain nerves, leading to him losing feeling in his legs. He was told he would never walk again. Before his paralysis, the London-based singer and dancer had "always wanted to run a marathon," he said, but he never made the plan to do so--until this year.

    During the London Marathon, the last two miles were the hardest. "At that point, I was exhausted. It was freezing cold, and I was hurting emotionally," Kindleysides said. But he kept going. "I didn't want to let people down. I had a team of eight, and I was raising money for The Brain Tumour Charity," he said. "I didn't want to let them down, myself down, and I thought if I would get this far, I would have to continue."So he continued and made history as the first paralyzed man to complete the London Marathon on foot.

    Then, recovering at home, he shared his accomplishment with his three children. "They used to say I'm the only dad in their whole school who's in a wheelchair, and now they say I'm their dad, the only one who has walked a marathon," he said.

    Kindleysides is training to complete three more marathons next year, including the London Marathon again.

    Food is necessary for offering energy to our bodies, but sometimes we buy too much of it at the store. When your food starts to go bad, there are many other ways you can still make use of it instead of throwing it away.

    Before throwing away old bananas, you can use the peels (皮) to shine up metals and leathers. Press the peel against the surface, move it backwards and forwards and then polish clean it with an old cloth. Banana meat is also good for reducing wrinkles. Put a bit on those trouble spots, let it sit for a while, and then wash it off, and your wrinkles will go away. Lemons are great for lightening skin and hair. If you have trouble with some skin diseases, like red spots on your face, put a bit of fresh lemon juice on them and leave it overnight. You'll notice a difference in the morning. Apples will help ripen (使成熟) tomatoes quickly when they are placed together in a paper bag, and orange peels are great fire starters for your next backyard campfire party.

    If your dog or cat brings home fleas, using salt is a great way to get rid of them around the house. Just pour salt into the vacuum cleaner (真空吸尘器). Let it sit, then vacuum up the fleas. The salt can kill the fleas. Be sure to throw away the vacuum bag or empty the vacuum bin immediately, or some of the fleas can climb out.

    Beer is a great hair lightener. If you are out of lemons, try dipping your hair in beer before going outside. Just don't forget to wash it out afterwards. Milk is great for removing dirty marks, especially if it is some type of ink.

    As you can see, there are many other uses for everyday foods around the house. So next time, before throwing food away thinking it is of no use, stop for a moment and think about all their uses talked about here.

    A university in southwest China's Chongqing City set up a reading room as part of a campaign (活动) that stops students from taking their mobile phones with them in case the device distracts (使分心) them from concentrating on their studies.

    Reportedly a student named Hu Xiaopeng participating in the campaign studied 530 minutes without using his mobile phone. Unlike Hu, another one picked up his mobile phone in less than 20 minutes. "Having seen many students use their mobile phones in the library, a habit that shortens their study time and negatively impacts their learning, we decided to open this reading room," said Zhang Shuran, the person responsible for the project at the university.

    Zhang added that students can keep their phones in appointed bags with numbers on them. The hags are placed on a desk near the door of the reading room. "Staff members at the reading room will check the phones when there's a call," said Zhang, adding that they will inform students when their parents or teachers call them, but will not tell students if an unknown person is calling or when there is a text message. Based on the time students hand in their phones when they come to the reading room and the time they get them back when they leave the room, Hu Xiaopeng from College of Animal Science and Technology of the university set a record of the longest time.Hu spent 530 minutes studying without using his phone. Though feeling somewhat surprised, Hu said, "It's bad to keep mobile phone with you when you are reading or studying."

    The campaign has attracted nearly 200 students since it was launched a week ago. Some Internet users praised the campaign. One user named Liu Jingchang said, "It's good. I don't bring my phone when going to the library in case I get distracted."

Last year, the Bureau of Labor Statistics reported that 55 million people in the U. S. are "gig workers" which is more than 35 percent of the U. S. workforce. That number is projected to jump to 43 percent by 2020.

People are drawn to gig work（零工）because it brings in a little extra income without a major time commitment. And recent technologies like Skype, Slack, and Dropbox have made the gig life a reality, giving you maximum freedom, an ideal work-life balance, and the chance to pursue your passions.

If you're thinking of joining the gig economy, it's never been easier. One of the great things about the gig economy is that you don't have a boss breathing down your neck. As a freelancer, you no longer have to cater to a company culture or work schedule that might cause physical or emotional stress. Instead, you get to choose the type of work you do and who you work with. But this degree of freedom requires a corresponding amount of discipline. With no boss to make sure you're on task, it's all on you.

A lot of gig workers start their careers by hopping on a project because the employer is desperate and in need of help. On the employer's end, it's tough to take on people for higher management positions when the pool of talent is full of gig workers who haven't been given an opportunity to improve their skills. Businesses have to evolve to learn how to account for an influx (涌入) of temporary workers. It is harder for gig workers to become skilled and get promoted.

The workforce is becoming more advanced and educated by the day. You have to keep learning and keep up with industry trends to maintain a competitive edge. This is true even for people in traditional office settings, but it's critical if you're your own boss.
