An American single-handedly cleared the mangrove forests on the coral islands of the Florida Keys from 10 tons of garbage

Namely: syringes, used hygiene items, furniture, auto parts and mirrors. It took five years. First, 35-year-old Andrew Otazo cleaned up an abandoned camp for fugitives. Then he began to collect garbage all over the coast, even while freediving. Andrew believes that a sewer system would solve the problem, but so far the local authorities have no plans to install it.

In broccoli, they found a substance that heals wounds twice as fast as antibiotics.

Israeli scientists have found that diindolylmethane (DIM), found in broccoli, cauliflower and other vegetables, heals wounds twice as fast as antibiotics. An ointment based on diindolylmethane was tested on pigs. It turned out that the substance interferes with the vital activity of bacteria. Thanks to this, the wounds are healed in five days. Medicines with antibiotics heal them in ten. Now scientists are working on the creation of a full-fledged ointment suitable for people. If the trials are successful, she could replace antibiotics.

Aquarium fish can count.

Aquarium fish can count. Aquarium fish, in particular zebrafish, perceive magnitudes - they understand how many objects are in front of them. For mathematical calculations, fish connect parts of the brain similar to those used by mammals and birds. This ability helps to assess the amount of food or competitors.

In China, a dead mosquito helped catch a burglar.

Police tracked down a burglar while investigating a burglary in Fuzhou City, Fujian Province. Examining the robbed apartments in one of the residential complexes, the investigators came to the conclusion that the offender stayed there for the night. Leftover noodles, egg shells and used mosquito repellent were found in the apartment. In addition, a crushed insect was found on the wall, which helped to solve the theft. After collecting blood samples left after the killed mosquito, the police conducted a DNA test, which led them to a previously convicted man named Chai. After 19 days, the thief was found and arrested. Further investigation uncovered three more burglaries by the same perpetrator.

The manufacturer of Skittles was sued over a poisonous dye that changes DNA.

American consumers have filed a lawsuit against Mars in a California state court. The plaintiffs allege that the level of titanium dioxide (E171) in Skittles candies is exceeded. This additive is used in paints, adhesives, plastics and can cause DNA, brain and organ damage, as well as damage to the liver and kidneys.

Scientists have figured out why woodpeckers don't get brain damage.

They disproved the popular hypothesis that why woodpeckers don't get concussions when they bang their heads on wood. Previously it was believed that the structure of the skull absorbs shocks, but the researchers proved that the heads of woodpeckers are more like hard hammers, rather than protective helmets. The authors of the new study believe this is because their brains are too small. The pressure ensures the safety of the woodpecker's brain, and the force on it is below that which can lead to a concussion. However, these birds are not immune to traumatic brain injury. They can get it if, instead of wood, they mistakenly start chiseling metal.

The largest ATM manufacturer in the US will add the ability to buy cryptocurrencies.

The U.S. arm of South Korean ATM maker Hyosung has signed a partnership with cryptocurrency provider DigitalMint that will allow the purchase of bitcoin at the firm's 175,000 ATMs located in the U.S. However, it is up to device operators to decide if they want to enable this service. Therefore, it is likely that not all of Hyosung's 175,000 ATMs will actually support the purchase of cryptocurrencies. According to the press release, it is bitcoins that will be available for purchase to users at the first stage. The United States has the largest number of cryptomats. According to Coin ATM Radar, 33,772 devices have already been installed in the country. And in total there are about 38,430 devices in the world.

Engineers have grown most of the human heart in miniature - and it's beating.

The cells that make up the heart were obtained from the cardiovascular tissues of young rats and then grown on a layer of a scaffold printed from a polymer with grooves to guide tissue growth. This flat mesh made the structure mimic the arrangement of the fibers of the human left ventricular heart muscle, from which blood is ejected into the aorta with one strong contraction. The difference of the new model is also that it is made of several layers of cells - just like a real heart.

Heinz created spoon-shaped french fries.

To commemorate National French Fry Day on July 13, Heinz released French fries in the shape of a Spoon Friez spoon that can scoop up the perfect amount of ketchup. While announcing the remarkable invention, Heinz said that he had also conducted a study showing that 95% of people refuse to eat potatoes without sauce. Another 84% of people are annoyed that they can't achieve the perfect potato to ketchup ratio.

People hear well in a dream, but do not understand what exactly.

Sleeping people hear almost as well as awake people - neurons continue to receive audio signals. But at the same time, the higher centers of the brain do not react to them due to the fact that alpha and beta rhythms subside during sleep. As a result, people do not understand what they hear, and do not foresee the further course of events.

In Japan, they developed vertical capsules for sleeping at work.

As planned by the partners, people will be able to sleep in vertical Nap Box capsules in a standing position, “like a flamingo.” Manufacturers claim that due to the special design with support for the head, knees and back, people will be able to comfortably relax in the shortest possible time and at the same time not fall. The developers of the sleep pod believe that their invention will help Japanese workers who often overwork to get better rest during breaks.

This is love!

Nicolae Ceausescu loved his dog Corba so much that he gave him the rank of colonel in the Romanian army and allocated a government limousine.

"Deep Web".

The Deep Web is not only a place to share criminal information. Drug dealing and stolen bank details are just a small part of the "deep web". The main part of it consists of libraries, scientific articles and databases that have nothing to do with crime, but are not indexed by Internet search engines.

Engineers have created a "conscious" robot.

He understands himself. The robot is like a baby who is studying his body, trying to understand the environment and himself in it. The robot creates a “mental” model of its body from scratch, without human help. The scientists placed a robotic arm around five video cameras. The robot looked at itself through the cameras, as if in a mirror. He began to wriggle and deform in order to understand exactly how his body moves in response to motor commands. Three hours later, the robot stopped. Its internal neural network has finished learning the connection between the robot's motor actions and the volume it occupies in the environment. The ability of robots to model themselves is an important skill. This not only saves labor, but also allows the robot to monitor its own wear and even detect and compensate for damage.

The microchip shortage is over.

It turned out that companies had accumulated too many chips in warehouses and the shortage turned into an oversupply. That's because during the pandemic, manufacturers stocked up on computer chips "just in case." Prior to this, just-in-time production was the norm for companies that ordered parts as close to production as possible to avoid excess inventory, reduce storage capacity and reduce costs. However, due to the fact that many chip manufacturers have reduced or completely stopped work, unrest began in the market - companies feared that there simply would not be enough chips for everyone. As a result, they bought chips in volumes that exceeded their real needs. So there was an artificial shortage.

In Chile, they caught a five-meter oar king - a harbinger of disasters.

Fishermen from the Chilean city of Arica pulled a 4.8-meter oarfish out of the water. This fish is called a harbinger of disasters: earthquakes and tsunamis. It is also believed that whoever catches it will be cursed. Herring kings can reach a length of 11 meters. They live at a depth of about a kilometer and appear on the surface due to storms and currents or weakness and disease.

Interesting facts about crocodiles.

Thanks to their powerful tail, crocodiles not only reach speeds in water up to 40 km / h, but also successfully jump out of the water to a height of up to 2.5 meters. To help their stomach cope with large pieces of food, crocodiles swallow stones. In addition, these boulders play the role of ballast when diving to depth.

Hiking boots with hydraulic pistons will keep hikers' feet from dislocating.

German startup Terrein is gearing up to launch the first Ascent hiking shoe with ankle protection. The boots have a pair of hydraulic pistons on both sides of the foot, which are in the deactivated position in the standard, safe position. They take the form of elastic straps and do not squeeze the foot. However, as soon as the foot begins to bend beyond the allowable limits, the piston works and firmly fixes the ankle, preventing it from moving in the wrong direction. Betterguards says their system has a reaction rate three times faster than a human's, so the shoes will protect you from injury before you even feel anything.

Migraine drug helped mice cope with obesity.

An international team of researchers found that a drug used to treat migraine reduces appetite and promotes weight loss in mice with alimentary obesity. As it turned out, this effect is associated with an effect on serotonin 5-HT1B receptors in the arcuate (arcuate) nucleus of the hypothalamus.

The world is 132 years from gender equality.

In Europe, the level of social parity between men and women is 76.6%. In North America - 76.9%. In these regions, people of different sexes will be equal in about 60 years. For the 12th time, Iceland has topped the equality rankings with a score of 90%. Then come Finland and Norway. From non-European countries, the top 10 included New Zealand, Rwanda, Nicaragua and Namibia. In total, there are 146 states on the list. The last five are Chad, Iran, Congo, Pakistan and Afghanistan.
