Rescue workers and thousands of volunteers are not the only ones who have won hearts and minds for their heroic efforts in the search for survivors after Tuesday’s powerful earthquake in Mexico. Fifteen dogs from the navy’s canine (犬科的) unit have assisted this week in the rescue efforts at the sites of collapsed buildings across Mexico City, where more than 50 people have been pulled alive from the ruins.

Of the canine heroes none is more famous or loved than Frida, a six-year-old white Labrador who in her outstanding service has won praise for her ability to detect (探测) people who have been trapped by various natural disasters. Over her admirable career she has found 52 people including 12 survivors in Mexico and other Latin American countries.

This week, Frida and Evil and Echo-two Belgian Shepherds that have also been specially trained for rescue efforts were sent to the site of the collapsed Enrique Rebsamen school in southern Mexico City.

Equipped with goggles that protect her eyes from dust and smoke, boots to prevent damage to her paws while she climbs over rough ruins, Frida took up her work looking into every bit of the ruins.

If Frida detects the presence of a survivor, she is trained to bark to warn rescue workers but if she detects a corpse she stops suddenly before continuing, her handler explained.

Eleven children were rescued from ruins at the school but this time human rescue workers rather than the dogs were the ones who located them.

However, that hasn’t stopped Frida from becoming a social media star and winning fame this week. Videos and other social media posts that highlight the work of Frida and her impressive record of detecting people trapped by natural disasters spread quickly online.

While she has yet to detect anyone trapped in the ruins this week, she and other rescue dogs are continuing to work tirelessly, searching through spaces that humans cannot reach. With the possibility that there are still people trapped alive, time will tell whether she adds to her rescue record.

Wherever we go, we are surrounded by history. Across the globe, cultural heritage is passed down through the generations. It is in the buildings and structures around us. It is in the arts and artifacts (手工艺品) we treasure. It lives in the languages we speak and the stories we tell. But today, it is under destruction as never before. Not only are the damages of time threatening our cultural heritage, but climate change, globalization and tourism are all demanding a heavy price. Technology is now the most important weapon in the battle. Here’s how technology is preserving our cultural heritage.

As you can imagine, creating the replicas (复制品) by 2 D images is extremely time-consuming. Increasingly, artificial intelligence (AI) algorithms (算法) allow millions of images to be stored in a matter of hours. AI will also make restoration (修复) and preservation of existing cultural heritage far easier and better than methods before.

Virtual reality (VR) technology will play a leading role in preserving our cultural heritage in the coming years. Many of the most important sites and architecture are easily damaged. The presence of hundreds of thousands of tourists on these locations is doing a great deal of harm. Wastes pile up everywhere, causing serious problems. As more cultural heritage sites and objects are digitally mapped and recorded, VR technology will increasingly become the way that people experience them. We’ll all finally be able to walk through places, look at (and touch) artifacts and works of art without ever seeing them with our own eyes.

Finally, our cultural heritage will be preserved by technology. Efforts in research, data sharing and project work will help promote and preserve the cultural heritage of countries all across the world.
