Hundreds of people die at sea every year due to ship and airplane accidents. Emergency teams have little time to rescue those in the water because the probability of finding a person alive fall dramatically after six hours. Beyond tides and challenging weather conditions, unsteady coastal currents often make search and rescue operations extremely difficult.

New insight into coastal flows gained by an international research team led by George Haller, Professor of Nonlinear Dynamics at ETH Zurich, promises to enhance the search and rescue techniques currently in use. Using tools from dynamical systems theory and ocean data, the team has developed an algorithm (算法) to predict where objects and people floating in water will go. "Our work has a clear potential to save lives," says Mattia Serra, the first author of a study recently published in Nature Communications.

In today's rescue operations at sea, complicated models of ocean dynamics and weather forecasting are used to predict the path of floating objects. For fast-changing coastal waters, however, such predictions are often inaccurate due to uncertain boundaries and missing data. As a result, a search may be launched in the wrong location, causing a loss of precious time.

Haller's research team obtained mathematical results predicting that objects floating on the ocean's surface should gather along a few special curves (曲线) which they call TRansient Attracting Profiles (TRAPs). These curves can't be seen with our eyes but can be tracked from instant ocean surface current data using recent mathematical methods developed by the ETH team. This enables quick and precise planning of search paths that are less sensitive to uncertainties in the time and place of the accident.

In cooperation with a team from MIT, the ETH team tested their new, TRAP-based search algorithm in two separate ocean experiments near Martha's Vineyard, which is on the northeastern coast of the United States. Working from the same real-time data available to the Coast Guard, the team successfully identified TRAPs in the region in real time. They found that buoys and manikins (浮标和人体模型) thrown in the water indeed quickly gathered along these emerging curves. "Of several competing approaches tested in this project, this was the only algorithm that consistently found the right location," says Haller.

"Our results are rapidly obtained, easy to interpret and cheap to perform," points out Serra. Haller stresses: "Our hope is that this method will become a standard part of the tool kit of coast guards everywhere. "

          When the dog named Judy spotted the first sheep in her life, she did what comes naturally. The four-year-old dog set off racing after the sheep across several fields and, being a city animal, lost both her sheep and her sense of direction. Then 
she ran along the edge of cliff( 悬崖) and fell 100 feet, bouncing off a rock into the sea.
         Her owner Mike Holden panicked and celled the coastguard of Cornwall, who turned up in seconds . Six volunteers slid down the cliff with the help of a rope but gave up all hope of finding her alive after a 90-minute search.
         Three days later, a hurricane hit the coast near Cornwall. Mr. Holden returned home from his holiday upset and convinced his pet was
 dead. He comforted himself with the thought she had died in the most beautiful part of the country.
          For the next two weeks, the Holdens were heartbroken . Then, one day, the phone rang and Steve Tregear, the coastguard of Cornwall, asked Holder if he would like his dog bark.
         A birdwatcher, armed with a telescope, found the pet sitting desperately on a rock. While he sounded the alarm, a student from Leeds 
climbed down the cliff to collect Judy.
         The dog had initially been knocked unconscious(失去知觉的)but had survived by drinking water from a fresh scream at the base of the cliff. She may have fed on the body of a sheep which had also fallen over the edge. “The dog was very thin and hungry,” Steve Tregear said , “It was a very dog. She survived because of a plentiful supply of fresh water,” he added.
          It was ,as Mr. Holden admitted, “a minor miracle(奇迹)”.

    Electrical devices (仪器) could soon use power made by human energy. Scientists say they have developed an experimental device that produces electricity from the physical movement of a person walking. British scientist Max Donelan and other scientists in Canada and the United States developed the device.

    The device connects to a person's knee. As the person walks, the device captures energy each time the person slows down. To do this, the device helps with the slowing down movement of the leg. The movements of the walking person push parts of a small machine that produces electricity. Using the device, an adult walking quickly could produce thirteen watts of electricity in just a minute. Donelan says walking at that speed could produce enough power to operate a laptop computer for six minutes.

    There are several possible uses for the device. Developers say it could help people who work in areas without electricity to operate small computers. The device could also be used in hospitals to operate heart pacemakers (起搏器). It could even be used to assist in the movement of robotic arms and legs.

    The experimental version of the device weighs about one and a half kilograms, but it is too costly for most people to buy. But the researchers hope to make a lighter, less costly version. An improved version should be ready in one year.

    The developers hope the device will one day help developing countries. Nearly twenty-five percent of people around the world live without electric power.

    A similar product was invented in 2005 by Larry Rome of the University of Pennsylvania. He created a bag carried on a person's back that also produces power from walking. The knee device does not produce as much electricity as the bag. But the bag requires the walker to carry a load of twenty to thirty kilograms.

    During this shopping season, salesmen will come up with different strategies to get your business. Many product companies use specific colors to cause positive emotions and compete for a sale. However, sight is not the only sensory (感官的) retail that companies use. Sounds and smells can also influence consumers' purchasing decisions.

    Nobel Prize-winning research shows that our sense of smell has great power to cause an emotional response. A study published earlier this year compared purchasing in a French flower shop when the smell of lavender (薰衣草) was given off and when it wasn't. It found that the smell increased the number of consumers' purchasing items and the amount of their purchases. An earlier study using Nike shoes found that consumers desired the shoes more, and were willing to pay more, when the room had a mixed smell of flowers. Realizing the subconscious impact of smell, many stores apply artificial scents (气味) through their heating and air-conditioning vents (通风口) or place scent machines above their doors. For instance, a coconut scent might make that bikini more appealing as you long for a vacation.

    Ever felt frenzied due to a store's fast-paced music? Or calmed by a piece of light music? A retailer's choice of music can have a big impact on consumers' moods. One study found that when subjected to loud music, consumers will spend less time in a store. But interestingly, the researchers did not find a difference in sales or customers' satisfaction. Another interesting finding from a recent study was that customers actually shop longer when exposed to unfamiliar music. Just as department stores use different scents in certain departments, many use different music in some areas to appeal to varying consumers.

    Well, you could always leave the store and take a break, but the food court probably isn't your best choices as brands like Cinnabon and Panera Bread also use scents as part of their customers' experience. Online retailers (零售商) use a variety of other strategies to get your business, but you can always neglect those and enjoy the familiar scents of home.

Fear of Missing Out

It's a common experience: You're scrolling through a social media page, and you see pictures of friends traveling or going to parties. Suddenly you start to wonder why you're not doing those things. Are you missing out on something fun and exciting because you're locked into everyday life? This experience has come to be known as the fear of missing out, sometimes abbreviated(缩写) FOMO.{#blank#}1{#/blank#} But with the rise of social media, FOMO is becoming much more common.

Wanting to be in on the fun when exciting things are happening is completely normal. But for some people, it can lead to an addiction to checking their phones to find out what other people are doing. Even while doing things that are fun or necessary, people can feel like there's something better going on elsewhere. This urge to connect can lead them to disconnect from the people they are actually with.{#blank#}2{#/blank#}It can even be dangerous; some people try to check messages while driving.

Remember that what people choose to post on social media does not necessarily reflect their life overall. People tend to pick and choose the things they share, so we only ever know a small part of anyone else's life.

{#blank#}3{#/blank#} You cannot be everywhere and do everything that might be interesting or productive, and that's OK.

It might even be necessary to turn off your phone or log out of social media for a while.{#blank#}4{#/blank#}You can even set particular times in your day to check email and social media. By stepping away for a time, you can help keep other people's lives in perspective.

Finally, focus on the things in front of you. Enjoy them, do them well and let everything else go. {#blank#}5{#/blank#}

Don't let the fear of missing out cause you to miss out on the good things you have in life. Relax, enjoy what you do and let other people enjoy their lives without envying them.

A. To some extent, people have always worried about missing out on things.

B. Without the social media you will get unconnected with the whole world.

C. It also prevents them from being satisfied with the good things in their lives.

D. When you fully engage with life, you'll worry less about what you're not doing.

E. Get rid of the constant reminders of everything that's happening in the world.

F. It's difficult to connect with the reasons why you choose not to participate.

G. It's also important to be humble and acknowledge your limitations.
