Cars could be able to "talk" to each other to warn about dangers on the roads using 5G technology in future, according to researchers.
Researchers at Glasgow Caledonian University (GCU) believe 5G may enable driverless cars to send each other messages about dangers such as ice or deep holes.
And they believe the high-speed, low -delay (低延迟的) nature of 5G will improve driverless cars to the point where they will be safer than the cars being driven today. They predict the number of road traffic accidents which cause more than 1. 3 million deaths and up to 50 million people injured worldwide every year will drop greatly as a result.
Dr Dimitrios, a member of the research group, said, “To have a better idea of what the future will look like, think of having cars that not only use sensors (感应器) to find what's around them, but also can talk to each other about safety information nearby.”
“I'm sure anyone who has had a bad experience on frozen roads would have benefited from knowing about the dangerous conditions ahead of time so they could have changed their speed or, if possible, even avoided that route (路线) altogether.”
With the help of 5G, an early warning system in vehicles will come into use within the next few years. Cars that are close enough to the danger area will pass warning messages to other cars around them using communication technologies, but also to cars further away using 5G, fast and reliably. Then those cars will send the same information to cars near them and 80 on, forming a joined-up.
5G is an exciting mobile technology, which will give a great boost to smart cities and autonomous (全自动的) vehicles among many other things.

We've seen a worldwide health crisis (危机) bring out the worst in some people, but fortunately, we've also been able to see it bring out the best in others.
A taxi driver in Spain has been providing COVID-19 (新冠肺炎) patients with free rides to and from the hospitals. Doctors and nurses wanted to surprise him with their thanks for helping out.
They tricked him down to the hospital under the pretense of needing to pick up a sick patient, but in reality, doctors and nurses lined the hall waiting to applaud (鼓掌) him.
“This is a surprise that has been given to a taxi driver who takes patients to the hospitals without charge,” wrote the taxi company that first shared the video.
The man seemed completely taken aback by the gesture, stopping in the middle of the doors as the whole room cheered for him.
He was also given an envelope full of money and the satisfying results of his own COVID-19 test.
The video has since been shared tens of thousands of times across the world, because kind gestures break the language barrier (障碍).
“When the crisis is finished, there will have been two types of people... the good and the bad,” one user wrote. “With workmates like him, I am proud to be a taxi driver, son of a taxi driver, and father of a taxi driver.”
With the word in hard times, just knowing good people are there doing good deeds is something we can all appreciate.

The Impossible Burger is a burger that tastes exactly like beef, but it was made using vegetables and science. There are many kinds of “veggie burgers” for vegetarians (素食者)，but this one is made for meat lovers. The company that makes this burger, Impossible Foods，wants to change the food that people eat to reduce climate change.
Scientist Celeste works on the flavor (风味) and texture (纹理) of the burger. She looks for the key points of beef its flavor, smell and look. Then those points are copied using plant based ingredients (成分)，which make the burger look and taste like blood and give it a meaty texture.
The Impossible Burger has the same nutrition as beef, without the unhealthy parts. In fact, taste, nutrition and reducing climate change were all equally important when creating the burger.
Cows are actually terrible for the environment. They need lots of land and water, and they create greenhouse gases. However, an Impossible Burger uses 95% less land, 75% less water, and creates 85-87% less greenhouse gases than a beef burger.
That's why this burger was made for meat lovers. The goal is for them to eat less meat in order to protect environment. At the same time they can still eat delicious burgers that taste like real meat.

There are many resources for people who are interested in volunteer tourism, but the best way to find these chances is to discover an organization you particularly want to work with. A simple Internet search for “volunteer tourism” will bring you many websites that offer this kind of travel experience. It is therefore important to research an organization before signing up to travel to a distant corner of the earth to become a volunteer. Many people rely on other organizations they know and trust them to do research for them. Many people sign up for volunteer tourism chances provided by their schools.
Before you choose a volunteer tourism trip, it is important to get a clear picture of how much money the trip will cost. It is also important to understand the kind of work that will be required of the volunteers, because not everyone is up to the challenge of spending many days doing heavy work. Any website can put up quotes from former volunteers that may not be true. If an organization offering volunteer tourism has an office in your city, take a trip to the office and speak with the people working there as this will help to get a better understanding of the financial and physical commitments (承诺) that volunteers must make.
It is also important to consider what kind of volunteer work you want to do. There are organizations that focus on volunteer chances for people who want to work on community building, others for people who want to volunteer in the field of education, and others still for people who have medical training and are willing to share their skills. There are also a number of volunteer tourism chances for people who want to help those in need.
Once you have found the type of volunteer work that you would like to do and created a list of volunteer tourism chances, it makes good sense to speak to former volunteers. It is a good way to choose the volunteer chance fit for you. It is also a good way to prepare for the trip and make it a success.
