Selfies（自拍）are developing daily and people are looking for the most creative ways to record their precious memories. It started with standard selfies taken with smartphones, then there was an era of selfie sticks. It's finally time to bring this selfie trend another step further and introduce a game-changer that is taking the world by storm!

Thousands of people suddenly started uploading their incredible aerial（飞行）selfies that left everyone wondering：how can I achieve the same? Soon, word about this device got out and the new type of selfie went around the world!

DroneX Pro is a pocket-size device that allows you to take ultimate（终极）selfies from crazy angles! This idea came up to two German engineers who love drones（无人机）but got fed up with carrying heavy ones. They wanted to create a device withoutditchingthe most valuable features of high-quality drones and that's how DroneX Pro was born! It is the same size as your smartphone yet provides you with the opportunity to achieve similar results as those bird's eye view shots taken with any professional drone!

DroneX Pro is easy to use, and takes no special knowledge to set up! All you have to do is charge the battery, install the app and in less than 10 seconds you'll be ready to go! Flying the drone is even easier! Smooth controls make it feel very natural-even kids are able to figure it out in no time!

Convenience, price, HD camera and controls designed to perfection make DroneX Pro most trustful. It ensures high-quality pictures, videos, and even the opportunity to live stream your adventures! You can completely forget the technical details of the flight and fully concentrate on the important things. It takes your pictures to the whole new level without difficulties and at the lowest expense! This new device is completely changing the way people take selfies.

An easily biodegradable（可生物降解的）material that could be “part of a global answer” to single-use plastic pollution has won its inventor, British designer Lucy Hughes , the international James Dyson Award.

Hughes' Marina Tex bioplastic is strong and flexible, making it a possible alternative for single-use packaging such as bags and sandwich wrappers. Its key ingredients are fish scales and skin, so it can break down in home food waste or compost bins.

Hughes created Marina Tex for her final-year project in the product design course at the University of Sussex. She had set out to create something using waste rather than unused materials, which led her to the UK's fishing industry. She ran more than 100 experiments to improve the bioplastic mixture, mostly using the kitchen stove in her student accommodation.

The fish scales and skin removed during processing usually encl up burnt or buried in landfill. And with “about 500, 000 tonnes of such waste produced by the country's fisheries annually”, it seems possible that Marina Tex could be used largely in industrial production. The material is low-energy to produce and doesn’t consume the earth's natural resources considering it's based on existing waste. It is also strong, boasting a higher tensile（可拉伸的）strength than the current material most commonly used for plastic bags.

British inventor James Dyson, who every year selects the grand prize winner in the international student design competition that bears his name, said that the material had the potential to replace traditional single-use plastics. “Marina Tex elegantly solves two problems：the ubiquity（无处不在）of single-use plastic and fish waste.” he said. “Further research and development will ensure that Marina Tex evolves further, and I hope it becomes part of a global answer to the abundance of single-use plastic waste.”

Businesses are finding more uses for Virtual Reality(VR) as the technology develops.

VR is no longer only for gaming or enjoyment. An American company called Blue Goji is using VR to improve one’s health by making exercise more fun.

Blue Goji has offices in Austin, the capital of Texas. The company showed its workout machine, called the Infinity treadmill (跑步机) at the recent South by Southwest festival. A person using the treadmill wears a virtual reality headset when exercising. Before starting, the user is connected to a belt to prevent falls. Then, the user plays a VR game while running on the machine. The game can transport the user into the virtual world, where he or she can be racing against virtual people.

The cost of the hardware and computer software program is $ 12,000.That is a lot of money for most people. But Kyra Constam of Blue Goji says the virtual reality treadmill is ideal for places where people go to exercise, like high-end gyms or recreation centers.

Recently, Leonardo Mattiazzi tested the Infinity treadmill. He thought the experience was surprisingly realistic. Mattiazzi said he had a strong feeling to actually get running and do something that pushed his limits. He said the experience was more interesting than running inside the gym without actually going anywhere.

Lots of VR experiences cause motion sickness because people are in motion during the game, but not moving in real life. But when the user is moving on the treadmill and in the game, the chances of motion sickness are reduced, Constam said.

After carefully studying the users’ experiences, Blue Goji plans to begin selling the Infinity treadmill to the public in 2019.
