Most people agree that eating healthy food is important. But sometimes making good food choices can be difficult. Now, there are apps that can help people learn about the food they eat to improve their health and their dining out experience.

    Open Table app

    Open Table app helps people choose restaurants when they want to go out to eat. It is a free service that shows users restaurant available based on where and when they want to dine. It gives users points when they make reservations(预定), which can add up to discounts on restaurant visits.

    Max McCalman's Cheese & Wine Pairing app

    Wine and cheese can be a great combination. But which wines go best with which cheeses? Max McCalman's Cheese & Wine Pairing app can help. It provides information about hundreds of different cheeses and suggests wines to pair with each. Max McCalman's Cheese & Wine Pairing app is free.

    HappyCow app

    Vegetarians do not eat animal meat. Vegans do not eat any animal products. The HappyCow app is made for both groups. Users can search for vegetarian-vegan restaurants and stores around the world.

    LocalEats app

    Restaurant chains, like McDonalds, can be found almost anywhere a person might travel. But sometimes travelers want to eat like locals. The LocalEats app is designed for that. It can help you find local restaurants in major cities in the US and in other countries. It costs about a dollar.

    Where Chefs Eat app

     “Where Chefs Eat” is a 975-page book. Most people would not want to carry that around. But there is a much lighter app version of the same name for just $15. Six hundred chefs provide information on 3,000 restaurants around the world on the Where Chefs Eat app.

    Several Jobs That Will Be Automated By Artificial Intelligence(AI) And Robots

    Translator

    Image recognition software and voice recognition software are bringing some major advances to language translation．Applications like Google's Word Lens can translate words from signs and documents in real time and there ale a lot of translation apps that allow you to type in a word or phrase and will translate it for you．

    Some will even speak the phrase for you and raw word-to-word translation will be fully automated soon．

Fast food workers

    Automated ordering booths have already made their way into a few McDonald's restaurants around the world，and cooking positions could be removed next．The booths probably can't handle customer service problems well，so televideo systems could bring in an office employee to deal with complaints．

Field technician

    New advances in the Internet of Things could make this work obsolete ．

Low-cost sensors combined with high availability cellular／satellite communications and cloud technology are being started to automate and alarm these sites，and can be checked and maintained from a desktop or mobile device．

Sales representative

    But，e-commerce is changing how we make purchasing decisions，especially those where there isn't much differentiation among the major competitors．

    If you're selling a high-differentiation product and／or a high-price，low-volume product you have some job security，but if you're selling a high-volume，low-differentiation product，you better start polishing your resume，said Doug Camplejohn，CEO of Fliptop．“These kind of product sales are all moving online．”

    A research project jointly carried out by scientists from several British universities and institutes has drawn people's attention to the toothbrush again.

    Researchers have found that your toothbrush is home to more than 100 million bacteria. But there are hundreds of microorganisms in the mouths and your toothbrush probably won't make you sick unless there is an unhealthy balance of bacteria. Our immune system can usually take care of bacterial invaders. However, if others use your toothbrush, or you use someone else's, bacteria can be spread.

    They have also found the toothbrush holders are the third-most dirty household items (behind dish sponges and kitchen sinks), thus advocating cleaning the toothbrush holder regularly.

    The storage of your toothbrush in your bathroom is also important. Here are some storage tips from the researchers to keep your toothbrush as healthy as possible:

    Put your toothbrush as far away as possible from the toilet flushing.

    Let your toothbrush dry thoroughly between brushings.

    Don't use toothbrush covers, which can create a perfect breeding ground for bacteria.

    Keep your toothbrush upright in a holder rather than lying down.

    Keep toothbrushes separate. If toothbrushes touch, they can exchange and spread bacteria.

    There are products available that claim to sanitize（消毒）your toothbrush. While some of these products do kill some bacteria, there is no evidence that using them will reduce your risk of illness, according to the researchers.

    They recommend replacing your toothbrush every three to four months or more often if you are sick or if you have a weakened immune system. Children's toothbrushes may need to be replaced more often than adult brushes.

    Finding a mountain goat resting high on a cliff(悬崖) might thrill many of the millions of tourists who visit Wyoming's Grand Teton National Park every year, but park officials say it might be time for the bearded animals to go.

    The problem, according to the park, is that Grand Teton's 100 or so mountain goats threaten about 80 bighorn sheep. The bighorn sheep numbered as many as 125 just a few years ago. The strong goats spread disease and compete with bighorn sheep for food. Unlike small-sized bighorn sheep, Grand Teton's mountain goats aren't native to the park. They were introduced to the park in the 1960s.

    Grand Teton spokeswoman Denise Germann said, “We've got a management responsibility to protect the native species. After hearing from the public on the proposal (建议) in January, park officials expect to decide as soon as mid-February on what to do about the mountain goats.”

    The goats are reproducing rapidly. Now might be the best time to reduce the animals before they're too many to bring under control, according to the Park Service.

    One wildlife biologist who studies bighorn sheep praised the proposal. Mountain goats' original habitat is nowhere close to where they've been introduced in the U.S. to provide hunting opportunities, said Rob Roy Ramey II, with Nederland, Colorado-based Wildlife Science International, Inc.

    Wildlife managers should get rid of mountain goats not only in Grand Teton but elsewhere to help struggling bighorn sheep, Ramey said. “Unfortunately, state wildlife agencies sell nonnative wildlife viewing opportunities to the public,” Ramey said. “This is not a zoo in the wilderness. It should really be for native wildlife.”

    A study examining the children of people evacuated(撤离) during the WWII showed the daughters of female evacuees were up to four times more likely to suffer from serious mental health conditions compared to those whose parents stayed at home.

    In the largest enquiry ever of its kind, researchers examined the health records of 3000 children of Finnish people evacuated to Sweden during the 1941-1945 conflict with Soviet Russia. The evacuees, many of whom were at a pre-school age, were placed with foster families in Sweden and were forced to learn Swedish, later returning to Finland. The study found that the female children of these girls had an increased risk of being hospitalized for conditions such as depression. However, this was not the case with children of boys evacuated during the war.

    The study could not determine why. One possibility is that the stress of the evacuees' experience affected their psychological development in ways that influenced their parenting style. Another possibility is that the evacuees' experience resulted in epigenetic changes—changed in the way genes are expressed. For example, the researchers mentioned an earlier finding that Holocaust survivors have higher levels of methyl groups bound to the FKBP5 gene and have passed his change on to their children. This higher level of methyl groups appears to change the production of cortisol, a hormone(荷尔蒙) that controls the stress response.

    "The Finnish evacuation was intended to protect children from the harm associated with the country's wars with the Soviet Union", said study co-author Dr Torsten Santavirta, from Uppsala University.

    "Our observation of the long-term psychiatric(精神病的) risk that reached into the next generation is concerning and stresses the need to weigh benefits as well as potential risks when designing policies for child protection".

    From quiet paths by a stream in a forest to busy roads running through a city, people have created various forms of routes in different places. These now exist all around us, and their use is imperative for societies. These routes have enabled people to move, transport things, and send information from one place to another quickly and safely. Throughout history, they have been important in our daily lives.

    Early routes were often formed naturally on land. They gradually developed over long periods of time while people traveled them on foot or horseback. A significant turning point in their history arrived when the first wheeled carts appeared in ancient times. Once this happened, people recognized the importance of well-maintained routes. Therefore, towns, cities, and entire countries improved them. As a result, life became more convenient, communities grew, economies evolved, and cultures expanded.

    People have established routes on water, too. Rivers and canals have served as effective routes for people to move around and carry things. For instance, in the old, Japanese city of Edo, water routes were used for the transportation of agricultural products, seafood, and wood. People have also opened routes across the sea. The seaways were critical for the navigation of ships, particularly in the days when they moved mainly by wind power. Using these sea routes, people could travel great distances, and go to places they had not previously been able to reach.

    People have gone on to open routes in the sky as well. Since the invention of the airplane, they have made it possible to travel long distances easily. Eventually, people became able to travel safely and comfortably high in the sky, and going vast distances only took a small amount of time.

    Today, we have a new type of route, the Internet. By using this worldwide route, people can easily obtain information that once was available mainly from books and face-to-face communication. They can also instantly send messages to large numbers of people all at once.

    As long as there have been people, there have been routes to connect them. Currently unknown routes will surely take us even further in the future.
