【推荐1】I couldn’t sleep at all last night, and my sister believes it was because I ate a bowl of really spicy (辛辣的) food before bedtime. However, I was skeptical about the connection between spicy foods and sleep. Can eating spicy foods before bedtime truly impact one’s sleep quality? Some people believe that eating spicy foods before bedtime can disrupt sleep by increasing body temperature and causing heartburn. It may be worth avoiding spicy foods close to bedtime.
To find out the relation, the researchers in Australia conducted an experiment to investigate the effects of spicy foods on sleep. They provided a group of individuals with delicious late-night meals, alternating (交替) between spicy and mild options. The results revealed that consuming spicy foods led to disrupted sleep patterns, causing participants to take longer to fall asleep and sleep for shorter time. This data supported the belief that there is a correlation between eating spicy foods and experiencing sleep disturbances.
While the exact mechanism(机制)by which spicy foods influence sleep remains unclear, researchers have proposed several possibilities. One is that stomach discomfort resulting from spicy food consumption may affect sleep quality. Additionally, the long digestion (消化) of spicy foods could delay the start of sleep. Furthermore, spicy foods contain something that can raise body temperature, which has been linked to poor sleep in previous studies.
Given these findings, it is advisable to avoid consuming spicy foods before bedtime to promote better sleep. Next time, I will follow my sister’s advice and opt for a milder meal in the evening to ensure a restful night’s sleep.

【推荐3】Where does the meat on our table come from? It usually comes from livestock like chickens and cows. But did you know that meat can also be made in a lab? US company JUST has announced that lab-grown meat could be on some restaurant menus in the United States and Asia by the end of 2018, The Independent reported.
“These meats include chicken nuggets (鸡块), sausage and foie gras (鹅肝酱),” Josh Tetrick, CEO of JUST, told The Independent. Lab meat is sometimes referred to as “clean meat”. It is made using the stem cells (干细胞) of living livestock. The cells need to be grown in a lab for a few weeks. For example, making a hamburger patty (肉饼) takes about nine weeks, CNN reported. This is faster than raising a cow, which usually takes over 20 weeks.
The first clean meat was a beef burger that was produced in 2013, but it was said to taste quite dry. How does clean meat taste now? Clean meat supporters told CNN that they think it tastes just like traditional meat.
Clean meat has other advantages. It is healthier than traditional meat. Meat producers can control what type of fat goes into the meat. They can produce clean meat that contains healthy fats, such as omega-3 fatty acids (脂肪酸). This kind of fat is good for people’s hearts.
Clean meat can also help to solve global warming. According to The Washington Post, about 14.5 percent of the planet’s greenhouse gas emissions (排放) come from raising livestock. That’s more than the emissions from every car, train, ship and airplane in the world combined. It is predicted that switching to clean meat could lower greenhouse gas emissions by 96 percent, The Independent reported.

【推荐1】A Natural History of the Future
Over the past century, humans have made great technological achievements with which we have found ways to control nature. From river dams (大坝)to huge one-crop fields, we continue to try to change nature for our goals so much that it seems we may be in danger of influencing it seriously.
In A Natural History of the Future, biologist Rob Dunn thinks that nothing could be further from the truth: rather than asking whether nature will let us live, we’d better ask whether we will let nature last. Although we try our best, or worst, to control the biological world, life has its own laws, and no matter what man does, he cannot change them.
Explaining several basic laws of ecology (生态), Dunn shows why life cannot be stopped. We grow one single crop on the field, only to find new life appearing to attack them. We throw away poisonous (有毒的) waste, only to find microbes (微生物) taking it over. And even in the London Tube, we have seen a new type of mosquito appear to take advantage of a place that is clearly not fit to live. Life will not follow our plans. Instead, Dunn shows us the future of living things and the challenges that the next generation may face.
A Natural History of the Future sets a new standard for understanding the different kinds of life and our future as a kind of creature.

【推荐2】The world is on a fast track toward an autonomous future. From off-road tractors and rural transit systems to air vehicles and space exploration, automation will enhance safety, increase efficiency and improve people’s lives. The more we can automate, the more we can protect people’s life and happiness.
To make the autonomous future safe and secure, manufacturers and operators will need reliable, assured positioning, said Michael Ritter, president of Hexagon’s Autonomy & Positioning division. At the HxGN LIVE Global 2022 event, he gave an overview of assured positioning and demonstrated how it provides the foundation for safe autonomy.
Ritter explained how positioning technologies can enable the future of autonomy for good publicity across industries including agriculture, mining and automotive. “We’ve all heard about autonomy,” he said. “What’s one of the big problems there? It doesn’t always work as advertised.” He mentioned Tesla’s AutoPilot as an example. “In our industry, we need to have autonomy solutions that we can trust.” “If that is not a hundred percent waterproof, crystal clear, and protected from outside interference (干扰) and cybersecurity threats, you can’t trust that positioning,” he said. “We have to know where we are at all times, and we cannot have that signal falsified (歪曲).”
While Ritter doesn’t think he’ll see the universal use of autonomous vehicles in passenger traffic during his lifetime “because laws will be in the way.” he said. “Applications in off-road autonomy — construction, mining and agriculture — are here today, which all take place in controllable spaces; laws are not such a big problem.” he said. “This is happening right now. We don’t have to wait 10 to 20 years for that.”
However, a big safety challenge in expanding autonomy is anticipating “all the stuff that could happen once in a lifetime,” Ritter said. Those can be overcome by real-life testing, multiplying that with simulation (模拟) “a hundred million times over,” and then going “back into real life” and performing “real, extreme testing.”

【推荐1】As we age, even if we’re healthy, the heart just isn’t as efficient in processing oxygen as it used to be. In most people the first signs show up in their 50s or early 60s. And among people who don’t exercise, the changes can start even sooner.
“Think of a rubber band. In the beginning, it is flexible, but put it in a drawer for 20 years and it will become dry and easily broken,” says Dr. Ben Levine, a heart specialist at the University of Texas. That’s what happens to the heart. Fortunately for those in midlife, Levine is finding that even if you haven’t been an enthusiastic exerciser, getting in shape now may help improve your aging heart.
Levine and his research team selected volunteers aged between 45 and 64 who did not exercise much but were otherwise healthy. Participants were randomly divided into two groups. The first group participated in a program of non-aerobic exercise-balance training and weight training-three times a week. The second group did high-intensity aerobic (有氧的) exercise under the guidance of a trainer for four or more days a week. After two years, the second group saw remarkable improvements in heart health.
“We took these 50-year-old hearts and turned the clock back to 30-or 35-year-old hearts,” says Levine. “And the reason they got so much stronger and fitter was that their hearts could now fill a lot better and pump a lot more blood during exercise.” But the hearts of those who participated in less intense exercise didn’t change, he says.
“The sweet spot in life to start exercising, if you haven’t already, is in late middle age when the heart still has flexibility,” Levine says. “We put healthy 70-year-olds through a yearlong exercise training program, and nothing happened to them at all.”
Dr. Nieca Goldberg, a spokeswoman for the American Heart Association, says Levine’s findings are a great start. But the study was small and needs to be repeated with far larger groups of people to determine exactly which aspects of an exercise routine make the biggest difference.

【推荐2】An open-air swimming pool in Bedfordshire, England, proved very popular this winter. The Woburn Lido is usually open from May to September, but this year it stayed open to swimmers throughout the autumn and winter months too.
Until the lockdown(封锁) for England was announced on 4 January, outdoor pools were allowed to remain open. “Demand has taken us by surprise.” said Murray Heining, a volunteer at the Woburn Lido. Over Christmas and New Year, in order to keep up with the demand from swimmers, the lido(露天游泳) had to offer extra slots for people to dive in.
Cold-water swimming has grown in popularity in the UK over the past few years. A survey found that 7.5 million people in England had swum in outdoor pools, as well as lakes, rivers and the sea, in 2018. In some areas, such as the river Wharfe in Yorkshire, this new trend has prompted environmental groups to ensure that the water is cleared of pollution and clean enough for bathers.
Some people make it a regular practice; others just enjoy a thrilling dip on Christmas Day, Boxing Day or New Year’s Day. Every year around the UK, people are photographed jumping into icy water, often in fancy dress, and the recent festive period was no exception, despite freezing temperatures.
The Outdoor Swimming Society classifies temperatures below 6℃ as “Baltic” and from 6-11℃ as “freezing”. They advise people to get in the water gradually, so as not to shock the body. Likewise, they recommend warming up gradually, and not rushing the process by leaping into a hot bath when you get out. Instead, they suggest layering up and drinking something warm.
It wasn’t just the water that was cold—many people experienced a white Christmas; snow fell in several counties including Yorkshire and Suffolk. Paul Davies, the UK Met Office’s chief meteorologist (a scientist who studies the weather), said the forecast indicates “the likelihood of the cold conditions experienced recently continuing through January”.

【推荐3】Hiking, that is, travelling on foot, can be a great way to spend time outdoors.
Map out your way before setting out. Tell your friends or family where and when you will be hiking, and when you expect to return.
In the case of lightning storms, stay away from tall trees and go quickly to the lowest—lying land you can find. On hot summer days, it’s necessary to bring clothing and a raincoat.
If you have worked out a hiking plan and told your friends or family your plan, help will be on the way as soon as they realize that you are missing. The best course of action is to stay in one position so that search groups can find you. Try to find a grassland or clearing where you may be seen from the air. A BDS is a good helper. With a BDS, your friends or family may easily know where you are.
| A．Water is the most important thing. |
| B．Buy a map of the area and familiarize yourself with the paths. |
| C．Going hiking with friends is even greater. |
| D．Take plenty of water and sun cream, as temperatures may increase fast. |
| E．BDS will also fixed in boats both of the sailing and rowing variety. |
| F．To bring a smartphone is also a good idea, but you may not have service in some areas. |
| G．However, basic hiking rules are necessary to ensure you have a safe trip. |
