Dog owners often feel a special emotional connection with their furry friends, but the new vest offers the owners an accurate understanding of what their pet is thinking. CNET reports that the Japanese company Langualess has created an Inupathy clip that measures the dog’s heart rate. It was demonstrated this week at the CES 2020 Consumer Electronics Show in Las Vegas, with a launch in the United States scheduled for late this year.
The vest analyzes the heart rate and predicts the emotional state of the animal, displaying it in color on the vest. The data was obtained thanks to tests on real dogs - animals were given a treat and measured heart rate. The vest transfers data to an application that allows owners to track their dog’s emotional state over time. If the vest shows blue light, the animal is relaxed. Red light shows excitement.
A study conducted last year showed that people can “read” the dog’s emotions, but the ability to recognize them is acquired with age and experience. Researchers invited 89 adult participants and 77 children to participate in the experiment. They were given photographs of dogs, chimpanzees and people, and asked to evaluate how the characters in the pictures show happiness, sadness, anger or fear. The experiment showed that older people were better able to recognize dog emotions.
U.S. startup Air Protein has developed a technology that can produce carbon dioxide proteins. It is reported by Meat-Inform.
It is reported that the new technology is based on previous research by American biotechnologists who, in the twentieth century, learned how to make food with the help of bacteria that feed on carbon dioxide and are able to turn carbon into valuable food components.
The developers hope that their invention will be useful to astronauts, since the manufacture of food products from carbon is quite convenient.
The main idea is that bacteria will process the air that the astronauts exhale into a protein flour-like mixture. Then add water and trace elements to it, which will make the taste of the new substance look like meat.
Also, this product can be suitable for both vegans and vegetarians.
Earlier, "Journalist" reported that scientists have found a way to make the body defeat cancer tumors.
The company plans to begin construction of a new generation city in the near future and the city of Shanghai in China was chosen as the territory for construction, Planet-today reports.
Vehicle-Road-City Integrated Smart City is the full name of this project, which will be of great value and practical value. Among ordinary people, he is already known as the "smart city." The Chinese startup Human Horizons wants to start developing and producing unmanned vehicles and designing high-tech roads.
Fifth generation networks will be a way to transfer data and access communication. It is also planned to create a special technology that allows communication with various representatives of the infrastructure.
The implementation of cloud computing and the processing of large amounts of data are expected. Three drones will operate on the territory of the “smart city” to effectively collect information.
A special technology based on the 5G system will control the proper functioning of infrastructure facilities. Autonomous movement will also be under control. According to unofficial data, the HiPhi 1 crossover can be used on the territory of the new building.
This is an osmosis based electricity production technology.
Scientists from the USA and Australia managed to create a durable membrane with which it is possible to produce electrical energy from sea water.
The idea is not new, but it was possible to develop its practical implementation only now, reports the BBC Science Focus Magazine.
We are talking about technology for the production of electricity based on osmosis - the process of one-sided diffusion of solvent molecules through a membrane with limited permeability. Molecules tend toward a higher concentration of solute and allow energy to be obtained in several ways.
"One way is to get energy from the pressure that water creates on the membrane. The second way is to get current from movement through the membrane of ions. This method is well suited for places where sea water meets the river," said scientists at the University of Michigan.
Until now, scientists have not been able to create a membrane that would not lose its properties with prolonged immersion in sea water. Now that the developers have launched special aramid nanofibres, everything worked out. "We have created a flexible and durable material of a new generation, which does not lose its unique properties even after several hundred hours in sea water," the authors of the project note.
F-Eye UAV Technology has tested an alcohol-powered drone.
Testing of the FY-36 drone on methanol was held in conjunction with the Dalian Institute of Chemical Physics, writes the South China Morning Post.
Today, several companies in the world are developing drones with fuel cells. Most of them use hydrogen as fuel.
The weight of the FY-36 drone, which was tested in China, is 15 kg. The device can carry another 3 kg of payload. The drone is made according to the airplane scheme with the main propeller in the tail. In addition, the device is equipped with two beams on which there are two electric motors with rotors - they are needed for vertical take-off and landing.
F-Eye UAV Technology has already completed more than 15 test flights. In the future, the developers intend to create a larger model of a drone that will carry heavy loads.
