Californian scientists found in which country people walk less
Physical activity, along with proper nutrition, is considered one of the main factors of a healthy lifestyle. Numerous scientific studies have found that regular exercise and walking can improve brain function, eliminate depression and help avoid obesity. At the disposal of scientists from California University (USA), about the physical activity of 700,000 people. Data on people’s physical activity were collected using the Argus app.
Combining all this information, the scientists found that the average user of fitness applications every day makes about 5000 steps. The most active users were residents of Hong Kong – on average, each of them every day makes about 6,880 steps. But the most low-active were the residents of Saudi Arabia, who every day make 3,103 steps every day.
According to the researchers, residents of some countries would be happy to be active, but they are hindered by circumstances. For example, in the American cities of Memphis and Houston walking is not welcome, so most of the population drives cars. But in cities with paths for cyclists and an abundance of different parks people love to walk.
The results of the scientific work were very interesting and useful. . On their basis, experts plan to develop a plan to help millions of people around the world who are at risk of being affected by weight gain. After all, obesity can cause the development of deadly cardiovascular diseases and diabetes.
Trained dogs to be used to detect coronavirus at airports
On September 30, the canine service of Russia’s Aeroflot carrier has started training service dogs to detect novel coronavirus infection in biomaterial from infected people.
Earlier it became known, a team of dogs trained to detect the COVID-19 began sniffing passenger samples at Helsinki Airport for checking in for a flight. In the canine test, a passenger, who is going to flight, swipes their neck with a gauze, places it in a can, which is then handed over to another room for a dog to sniff and to deliver an immediate result. In case of a positive result, a passenger is offered to pass a real test for COVID-19. One of the advantages of the canine test is its prompt results. Finnish veterinary specialists say that a team of sixteen specially trained dogs is able to detect cases of the infection several days before patients get any clinical symptoms of the disease.
Canadian designer creates portraits of Roman emperors
Daniel Voshart, a Canadian designer who works with Virtual Reality, has created photorealistic portraits of ancient Roman emperors by using 800 images of busts, which he transformed with the help of a neural-net tool named ArtBreeder. The work involved a great deal of research, as the designer cross-referenced the emperors’ appearances, such as face, hair, eyes and skin tone, to historical texts and coinage.
According to designer, Artbreeder known as a generative adversarial network that cannot be called artificial intelligence. The specialist considers the network to be a machine learning method.
Daniel emphasized that each likeness is an artistic interpretation. By the nature, more art than science. The designer specifically tried to create portraits of emperors that looked convincing in their own right as during the last year of their lives.
Voshart’s goal was not to romanticize emperors or make them seem heroic. In choosing bust or sculptures, the approach of designer was to favor the bust that was made when the emperor was alive. Further, Daniel deliberately worsened the result a little, since, according to his theory, the artists of Rome were likely trying to flatter their emperors.
In total, under the project, painstaking portraits of the 54 Roman emperors of the Principate period, which spanned from 27 BC to 285 AD, have been created.
Singapore scientists devise a new approach to treat cancer
A research team from Singapore devises a novel alternative approach to kill cancer cells. The new approach is based on the increased demand for amino acids inherent in tumor tissues. The researchers took a silica nanoparticle and coated it with a specific amino acid – phenylalanine – that is known as an essential amino acid. Scientists are confident that due to the need for phenylalanine, cancer cells concentrate around themselves nanoparticles that causes cancer cells to self-destruct.
Researchers have found cancer cells are killed in lab experiments and tumour growth reduced in mice.
The major advantage of the novel approach is that the nanomaterial is used as a drug instead as a drug-carrier. Here, the cancer-selective and killing properties of nanoparticles are intrinsic compared to the use of drugs, which, as a rule, cause damage to healthy tissues.
Experts are convinced that the approach to kill cancer cells discovered by them can be viable way to treat people.
Scottish man and his cat travels 16 thousand kilometers
When former Rugby player Dean Nicholson from Dunbar, Scotland, packed his job in to travel the world, he hoped it would be a life-changing experience. The 31-year-old man left Scotland and travelled to Amsterdam. He passed through Belgium, Greece, Switzerland and Italy before boarding a ferry to Croatia.
But when he was crossing the Bosnian border into Montenegro, his plans had to change a little bit. He was going up a steep hill when suddenly he heard a desperate meow behind him. When he noticed a tiny kitty, he decided to stop for a second to stroke her and move on. However, the stray cat had other plans as she immediately showed her affection. She just could not leave his side, and even though Nicholson did not plan a cat adoption, he soon fell in love with her.
Dean went to find out if she was microchipped. But, the little kitten, who he named Nala, wasn’t and she climbed up on his shoulder and fell asleep and he just thought that was it, she was coming with him on the world tour.
Dean realized the tiny four-legged friend had changed him. He said: “She has taught me just to slow down and enjoy life a lot more. Having her on the bike her needs come first and it slowed the tour down and now we stop and play a lot.”
Dean had to organize a pet passport for Nala, and now the world is their oyster. So important is his furry friend that she even dictates the itinerary. For example, the traveler could not go through Iran with the cat because they would not let her stay in hotels so he missed that.
Everywhere they go, Dean and Nala attract attention. Local people are in awe of the little purring passenger who travels in a basket on the front of his customized bike or on Dean’s shoulder and they always ask for a picture of her.
Upon returning to his hometown, Nicholson shared a photo album about the trip on social media.
