Air pollution

Air pollution has caused hundreds of thousands of deaths. An international team of scientists has found that air pollution has caused more than 100,000 deaths in tropical cities. The researchers analyzed air quality data for 46 metropolitan areas across Africa, Asia and the Middle East using instruments aboard NASA and European Space Agency satellites from 2005 to 2018. In all cities, experts have found a significant annual increase in the content of pollutants that are directly hazardous to health. For example, nitrogen dioxide increased by 14 percent, fine particles by eight percent, ammonia by 12 percent, and volatile organic compounds by 11 percent.

The biggest Hummer

The world's largest Hummer has joined the collection of a sheikh from the UAE. The monstrous detailed copy of the Hummer H1 is 14 meters long, 6 meters wide and 7 meters high. It runs on 4 diesel engines and has a toilet with a sink on the ground floor and a guest lounge on the second floor. This monster can move at a maximum speed of up to 32 km / h. By the way, the Arab Sheikh Hamada bin Hamdan Al Nahyan is obsessed with SUVs: he has 718 of them, thanks to which he got into the Guinness Book of Records.

Snoring danger

Doctors have warned of the deadly danger of snoring. An otolaryngologist, a doctor of the highest category, warned that this ailment could cause respiratory arrest, which, in turn, could lead to a heart attack and stroke. The doctor also named the possible causes of snoring. It can appear due to a congenital or traumatic deviated septum of the nose, the growth of the inferior turbinates, and even due to excess weight. The ENT urged people suffering from snoring to immediately contact a doctor who will conduct an examination, identify its cause and tell you how to get rid of it.

Love for alcohol

The love of alcohol could have come to man from monkeys. Primatologists in California have found that spider monkeys in Panama are purposefully looking for fruits that contain ethanol. Moreover, a urine test showed that monkeys process alcohol almost like human organisms. And perhaps our passion for drinking stretches from the most distant ancestors

The most powerful antibiotic

Created the most powerful antibiotic in history. One of the main problems of modern medicine is superbugs that are resistant to antibiotics. But British scientists have finally synthesized teixobactin, a substance that has been tested to kill even Staphylococcus aureus, which is no longer affected by most modern antibiotics.

The smartphone myth

Smartphones do not increase the risk of brain tumors. Oxford published the results of a study of 776,000 participants who used phones for 14 years. No abnormal jumps in tumors and cancers of the brain in comparison with the average were found. The smartphone myth

Ghost village

In southern Italy, in the Basilicata region, there is the ghost village of Krako. On one terrible day in 1963, an earthquake of unprecedented strength shook the rocks, causing many victims and destruction. It became really unsafe to stay in the houses further, and it was after this event that people preferred to move to the neighboring settlement of Craco Peschiera, and nature completely took over their former houses.

We invent a bicycle

Designer Stefan Henriks introduced the concept of an "all-wheel-drive" bicycle on an infinity-shaped caterpillar. The tire guides are dynamic, they are placed on shock absorbers, so they can bend along the road surface. However, the design is in the early prototype stage.

Lithium mining

Elon Musk tweeted that Tesla may be forced to mine lithium, a key component of electric vehicle batteries. Tesla started thinking about independent lithium mining back in 2020. The company hopes that this will allow it to reduce the cost of batteries.

An unknown object from another star system

Officially - the Earth was visited by a piece of matter from another star system. The US Space Administration has declassified evidence that a meteor that landed in Papua New Guinea in 2014 was from another star system. For many years, Harvard has been doing trajectory research and finally confirmed it. The point is small - to try to get the remains, because he fell into the ocean. But it's worth it! Just think, this is the first time in history that something from another star system, located many light years away from us, flew to Earth.

Path to immortality

Human cell rejuvenated by 30 years. Scientists at Cambridge have been able to reverse aging by making a cell behave like it's 30 years younger. This can be a very important step in matters of immortality and regeneration.

ISS welcomes new guests

The first fully commercial flight was launched to the ISS - a crew of 4 went on a SpaceX Falcon 9 rocket. On the 8-day tour flew: former NASA astronaut Michael Lopez-Alegria, businessman Larry Connor, investor Mark Party and entrepreneur Ethan Stibbe. The cost of the flight was about $55 million per passenger.

Unusual sneakers

The Australian brand Volley has released ordinary sneakers with an unusual decoration - a human hair wig. A strand of hair imitates a popular hairstyle from the 80s - a mullet. Velcro accessory - if desired, it can be unfastened. Crosses are presented in men's and women's versions, the price is $ 85.

Artificial finger

Scientists from Britain have created an artificial finger capable of touch. A 3D-printed prosthesis using special sensors can generate signals similar to those produced from various human nerve endings. In the future, this will allow the creation of "live" prostheses and robotic manipulators for working with fragile objects.

Complications of COVID-19

The risk of blood clots after COVID-19 has been identified. Swedish scientists have found that the risk of deep vein thrombosis (occurring most often in the legs or pelvis) increases five times within three months after infection. Particularly susceptible to the appearance of blood clots were people who were ill with a severe form of coronavirus, as well as those who have chronic diseases. Complications of COVID-19

Defense strategy

Barramundi cod fry Juveniles have a white background with round black spots and constantly swim head down, some juveniles such as this cod tend to swim vertically with a quick tail wag. They do this to mimic flatworms, sea slugs, which are toxic if ingested. A very smart defense strategy to avoid predators.

Cyber Rodeo

The Cyber Rodeo party we wrote about earlier was a great success. The celebration took place last night at the Giga Texas site, which is now Tesla's global headquarters. During his speech, Elon Musk promised that the Cybertruck and Tesla Semi would be put on the assembly line in 2023. Among the planned products that should appear in the near future, robot taxis and the Tesla Optimus robot were also named.

Mushrooms can talk

This conclusion was made by scientists from the University of Bristol. They found that mushrooms exchange electrical impulses through the mycelium (mycelium). And the structure of these impulses surprisingly resembles that which is characteristic of human speech. The researchers counted up to 50 words. It is likely that such signals help maintain the integrity of the mushrooms - similar to how wolves howl to keep the pack intact - or communicate the detected food to other parts of their mycelium.

Benefits of coffee.

Benefits of coffee. The benefits of coffee for people over 50 are revealed. Scientists from the Australian Institute of Heart and Diabetes named after Baker have found that such an everyday drink as coffee is useful for people over 50 years old. Researchers have revealed that drinking several cups of the drink daily can improve the functioning of the heart muscle. In addition, the experts concluded that coffee has a positive effect on people who already have heart disease. It turned out that in this case, the drink helps to reduce the risk of early death, the scientists noted. They urged not to avoid drinking it, but rather to drink coffee even for those who have heart problems.

Consequences of mild forms of coronavirus for the brain

According to scientists, the disease can provoke the appearance of a large number of foci of inflammation and small hemorrhages. The study was conducted on monkeys that did not experience severe symptoms of COVID-19 during the observation, so biologists did not expect to see a significant negative effect on the body. In some cases, these pathologies led to large-scale death of nerve cells, which formed hypoxia in certain areas of the brain. According to researchers, this phenomenon explains clouding of consciousness and other disorders that occur in the head during the acute stage of the disease.
