The Mercer Amsterdam brand introduced sports shoes made from recycled pineapple leaves. A shoe maker buys raw materials in the Philippines from local crop pickers. Then, a microfiber is produced from the plant fiber, - reports Around the World. This process, according to the manufacturer, does not require large amounts of water and electricity, and the material itself can be an alternative to natural leather. These sneakers are worth 250 euros. They will go on sale after March 31, but for now are available for pre-order.

The Japanese government is starting to test carbon dioxide consumption methods from the atmosphere.
This decision was made by the Ministry of Environment of the country, reports Ukrinform.
The resulting resource will be used as fuel. The plans of the Japanese government - to convert gas into natural resources.
Japan has already introduced many measures to reduce the percentage of greenhouse gas. But it is not yet clear how to reduce carbon dioxide in the atmosphere.
Recall, scientists have announced the possibility of the disappearance of clouds. In their opinion, a decrease in the concentration of carbon dioxide in the air will lead to this.
In the next century, our planet may lose the clouds that protect it from overheating. If this forecast becomes a reality, a climatic catastrophe on Earth will simply be inevitable, and its consequences will be much larger than any of the worst predictions.
This opinion is shared by scientists working at the California Institute of Technology. According to experts, the increase in concentration in the atmosphere of carbon dioxide, is fraught with the disappearance of the cloud layer, intended to shelter from sunlight the vast majority of the oceans.
According to them, when the concentration of carbon dioxide in the atmosphere begins to exceed 1200 ppm, a kind of change will occur and the so-called non-return point will occur. It is then that the clouds will begin to rapidly collapse.
And this, scientists say, will lead to a significant warming of the ocean. Kerry Emanuel, an expert in atmospheric physics, after reading the results of this study, is convinced that this turn of events is quite real and poses a real threat to humanity, as well as to all life on our planet.
At the beginning of the XXI century there were 10 of the hottest years in the entire history of meteorological observations, and in 2018 the temperature of the world's oceans reached a record high. Climate change is already causing damage to the planet, and starving polar bears are just one of his examples.
As the temperature of the ocean rises, and the ice sheets, the hunting grounds of polar bears, are melting, these large carnivores have to look for new places to eat.
It is known that weather conditions strongly influence the state of health and mood of a person. Scientists decided to determine the place with the most suitable climate for humans. First place went to Costa Rica. The second, respectively, Greece, the third - Cyprus. Next come Malta, Spain, Portugal and Mexico.
Despite the hot climate, Greece and Cyprus were in the top three. Sunny climate makes the country attractive to many citizens. So, in this country, 300 days out of 365 a year the sun shines, and winters are much milder.

Engineers from the United States have developed a robot that will help people to eat, not able to cope with this daily action on their own. Attached directly to the wheelchair, the system recognizes the products on the plate, calculates how to take each of them so that it does not slip off the fork and the ward was comfortable to eat, and then brings the product to the user's mouth so that he can reach it with a flick of his head .
According to a press release from the University of Washington citing data from the 2010 census, in the United States alone about a million adults need help with food.
“The goal of the project is to give people a little more control over their lives,” the researchers explain.
To teach the robot to take food from a plate, the authors of the development have previously wondered how healthy people eat. To do this, they provided the volunteers with a plate with more than a dozen different food samples and asked them to “feed” the dummy. Sensors embedded in the smart plug recorded the movements of the subjects.
It turned out that people use a whole set of different strategies. So, if the product is very soft, such as a peeled banana, the volunteer stuck the fork at an angle so that the piece did not slip from it along the way to the mouth. If it was about hard carrots, the man deliberately shook the fork to stick it deeper without any extra effort. In addition, when a volunteer needed to pin a product with a thick skin and a soft inner part, like grapes or tomatoes, he first made considerable efforts to pierce the outer part, and then sharply reduced them when he reached the inner part.
Thus, it turned out that the robot needs to adjust the angle and force of depression depending on the product it is dealing with. For this, the device was equipped with a special plug printed on a 3D printer. The degree of deformation of the gel in the sensor attached to it indicates to the system how solid a particular piece is, actually replacing the tactile sensations.
However, the wisdom of the meal does not end there. It is important, after all, not only to bring food to the mouth, but also to take it so that it would be convenient for a person to eat it. For example, a small piece that fits in your mouth as a whole can be pierced in the middle. But a long carrot, from which it is supposed to bite off a piece, it is better to take it from one end and bring it to the mouth of the other. These subtleties also had to teach the system.
The authors tested their offspring on volunteers who were supposed to feed the robot with different foods. The computer vision system recognized the food, and the roboruka stuck a fork into it and brought it to the subject's mouth. In general, the tests were successful.
“According to our idea, the robot will allow people in need of help to have lunch or dinner on their own,” engineers say. “As a result, a medical professional can put on a plate and do something else while a person eats.”

The United States Patent and Trademark Office (USPTO) issued Samsung a patent for a smartphone with a very unusual design. We are talking about the device with a flexible body. And as you can see in the illustrations accompanying the document, the device will be able to bend in two places - in the upper and lower parts of the body.
But the main feature of the novelty will be a removable main camera. Thanks to a special mount, users will be able to connect an optical unit when necessary.
Theoretically, this approach will allow you to install different lenses for shooting in certain conditions. In addition, it will be possible to use optics with zoom in a large range.
The images indicate that the removable lens is quite large. Therefore, in practice, such a decision may be controversial.
However, while the unusual Samsung smartphone exists only on paper. About the possible timing of its appearance in the commercial market is not reported. Most likely, the device will remain a design development.

We have already been able to observe various technological improvements concerning the increase in the lifespan of various devices from a single charge — however, today the results of an interesting technical experiment related to an increase in the time and distance of the drone’s flight were presented. It is about the development of Professor Vikas Prakash of the Case Western Reserve University, which is a new type of single-propeller drone with a wide wingspan, inside which are placed additional batteries and battery connections to increase the charge capacity of the drone. And the test results turned out really great.
The wingspan of such a prototype drone itself reaches about 2.1 meters, which is quite large, but not the biggest indicator. Professor Prakash's idea was to unload the main body of the drone by placing additional batteries inside the wings, thereby simultaneously providing a looser space in the middle of the drone, which allows it to increase the luggage compartment, if necessary.
In addition, the integrated wing-mounted battery system made the drone more maneuverable and agile, which is an exceptionally positive aspect of the innovation. Tests were conducted in the airspace of Springfield-Beckley airport in Ohio, USA - the drone was first launched without a wing-mounted battery system, and then with it. Without it, the drone hung in the air for about 91 minutes, and with this system he managed to hold out for 170 minutes - which is almost three hours, which is really an achievement for small and medium budget drones.
Thus, the illustrated indicators clearly prove that the development of an under-roof system for additional batteries is a great idea in increasing the autonomy and life expectancy of an average drone from a single charge. However, there are still some controversial points and aspects in the system that are directly related to the correct selection of additional structural features and moments.
