People often say that everything was better back then: the grass was greener, and it was so much easier to live. Feeling nostalgic is good, but present times can also be great. We live in a world of constant technological progress, which positively affects both us and nature.
At Bright Side, we would like to tell you about 12 positive changes that happened recently or that are happening right now.
1. Space tourism is closer than ever.
According to forecasts, the size of the space tourism market will reach $3 billion by 2030. A few companies are competing for the right to send tourists into orbit, and Elon Musk’s company, SpaceX, is among them.
Several successful trips happened in the 2000s, and until recently, space tourism was forgotten. But in the fall of 2021, new trips were planned, which means businessmen, philanthropists, scientists, and doctors will eventually fly into space. Who knows, maybe even an ordinary person will be able to fly to the moon for the weekend in a dozen years!
2. Technology is being developed that will level out our brain.
Elon Musk’s project, Neuralink, is a microchip that will create a connection between the human brain and a computer. In the future, it will help treat Parkinson’s disease and can even give robotic prosthetics haptic feedback.
In addition, Neuralink is capable of helping people with anxiety and depression who can’t get themselves to leave the house. According to Musk, the chip will ease the person’s condition so that they can at least begin their treatment.
3. Scientists succeeded at growing a human tooth.
Dentures have a rich history. Long ago, people used ivory, beeswax, and wood to replace lost teeth. Nowadays, more modern materials are used, and a tooth is still made of artificial materials and has to be attached to the jaw with a complex structure.
Recently, scientists managed to grow a bioimplant that is very close in structure to a real tooth, and this is a huge step in dentistry. In addition, this technology has already made it possible to grow tooth enamel.
4. Ophthalmology isn’t at a standstill either.
Recently, ophthalmologists of the Cheboksary branch of MNTK “Eye Microsurgery” invented an iris prosthesis combined with an artificial lens, which will help people with eye injuries to rehabilitate. The unique invention has already been patented under the name “iris-lens diaphragm” and put into practice.
Other inventions are also nice, like self-adjusting eyeglasses. Farsighted people will be able to customize the same pair of glasses without having to use different eyeglasses for reading, walking, etc.
5. The giant panda doesn’t belong on the endangered species list anymore.
Previously listed as endangered, the giant panda is now listed as vulnerable due to effective forest protection and reforestation. Thanks to conservation measures, its population is slowly growing.
6. There are more trees in the world now than there were 100 years ago.
It’s logical to assume that deforestation and large-scale forest fires greatly reduce the percentage of trees on the planet. But as it turns out, despite natural disasters and human activities, there are much more trees on Earth now than there were 100 years ago. During this time, the number of trees has grown by 400%.
7. There will be high-speed trains.
Virgin Hyperloop is developing the technology for passenger pods that will hurtle at speeds of up to 750 miles an hour through almost air-free vacuum tunnels using magnetic levitation. According to forecasts, Virgin Hyperloop plans to start commercial operations as early as 2027.
8. Companies will develop biodegradable plastics.
Scientists have long sounded the alarm on plastic waste getting into the ocean. Up to 12.7 million tons of plastic get into the water every year — the scale of the pollution is terrifying. It’s necessary to solve this problem at a global level and not only at the expense of individual activists.
Greenpeace has already been researching biodegradable plastics. This material is made from sugar cane and is much easier to recycle.
Others scientists are following in their footsteps too. Scientists from Astrakhan State University developed cling film from gelatin, and a Finnish company launched the production of drinking straws from recycled wood waste.
9. 3D printing has already been used in the medical and food industries.
3D printers are no longer perceived as an innovation, but many people are not aware of their capabilities. Meanwhile, technology in this area has advanced far enough to produce meat without the use of animal products.
It has also been used in medicine. A doctor can, for example, create an exact copy of a patient’s spine in order to plan a complex operation or make a perfectly fitted limb prosthesis.
10. Virtual trips will replace real ones when you can’t travel in person.
When there’s no opportunity to see a popular attraction with your own eyes, you can just flip through photos on the Internet or go on a virtual tour. VR technology allows you to put on a helmet and travel to any part of the planet and beyond.
As of today, you can’t smell or feel the sea breeze with your skin while in virtual reality, but it seems that the inventors are gradually working on this.
11. Artificial Intelligence has reached unbelievable heights.
We’ve heard many times that AI beat the world’s best chess players. However, not so long ago, the computer outdid itself — artificial intelligence managed to beat the champion in the Chinese game of Go.
Until recently, Go was the only game in which humans were superior to AI. After the computer won against the Korean champion, Lee Sedol, the gadget ended his career with the words, “Now there is an entity that can’t be defeated.”
The development of AI will help automate many areas of production where human resources were previously required. Now robots will be able to replace them. Although many fear that AI will leave humanity behind, the developments in this area, on the contrary, will generate new professions and jobs.
12. Reproductive medicine took a huge step forward.
Some time ago, if a doctor diagnosed a woman with infertility, it meant that she could never have children. This was the case until 1978, or rather, before the first successful birth of a child after in vitro fertilization treatment.
With the help of this technology, more than 8 million children were born in the world, while infertility and age are no longer considered barriers to giving birth to a healthy child.
