Satellite Internet Elon Musk is rapidly gaining a subscriber base

SpaceX, in a report, announced that the Starlink satellite internet service already has over 400,000 subscribers worldwide (both individuals and legal entities). Interestingly, just two months ago there were 250,000 of them, and at the beginning of the year - 145,000. SpaceX has launched 2,405 satellites so far, of which 2,374 are operational.

In the United States, three centuries later, the last "Salem witch" was pardoned.

The state of Massachusetts has officially pardoned the last Witch of Salem, Elizabeth Johnson, 329 years after she was sentenced to death. In the 17th century, it was never executed, but the American woman still remained the only unrehabilitated victim of the trial. Perhaps because she has no offspring. During the Salem witch hunt from February 1692 to May 1693, English Puritan settlers killed 20 people, about 200 were sent to prison, where some died. They fell victim to superstition, fear of disease, and settling scores. Elizabeth was 22 at the time of the trial.

A Japanese man with dreams of becoming a dog spent $15,000 on a realistic costume for his favorite breed, the Border Collie.

Film maker Zeppet designed a costume for a dog fanatic in 40 days. Now he publishes videos of how he gives his paw, falls on his back and plays tennis.

In the USA, they created edible electrical tape.

Chemical and biomolecular engineering students have created edible Tastee Tape to keep burritos (or shawarma) from falling apart.

China is preparing to destroy Starlink?

A group of Chinese scientists published a study in which they described the theoretical methods and plans for the hypothetical destruction of Elon Musk's satellite constellation. Let's hope that the destruction will indeed be hypothetical.

In South Sudan, a ram was imprisoned for murder.

The court sentenced the ram to three years in prison for the murder of 45-year-old Adye Chaping. The animal will serve time at the Aduel County military base. According to investigators, the ram hit the African woman several times with his head and broke her ribs. The woman died on the spot from her injuries. As compensation, the court also ordered the owner of the ram to give five cows to the family of the deceased. Once imprisoned, the guilty animal will most likely be handed over to the victims, as required by local law.

Lost ancient cities with pyramids, canals and paved roads have been discovered in the Amazonian jungle.

The discovery was made from the air using lidars. Standing on the ground, it is almost impossible to see fragments of buildings under the dense vegetation of the jungle. In total, scientists have found about 15 unknown settlements and two new large cities. They were named Kotoka and Landivar. The discovery of lost cities will force anthropologists to take a fresh look at the culture and life of the peoples of pre-Columbian America.

Humans can hear underwater just as well as seals.

The study involved seven volunteers and several marine mammals. It turned out that the average threshold of hearing under water in humans is 71 dB. This corresponds to a frequency of 500 Hz. The 500 Hz threshold corresponds to how animals such as cormorants and seals hear underwater. At the same time, scientists note that marine animals, unlike humans, can also hear very loud sounds.

NASA has announced a 30-day manned mission to Mars.

So far, we are talking about a working concept, but there are already some details. There will be 2 people on the team, and their first priority will be to test the possibility of working on Mars, study the effect of the red planet on health and lay the foundation for the following missions.

Quantum Internet has become a little closer.

Up to this point, the record was quantum teleportation of data between two computers. However, one of the universities in the Netherlands announced that they had built a small local network capable of transmitting information to physical locations using quantum teleportation. This is very significant - after all, we are talking about a hypothetical Internet with zero delay and infinite speed.

In Illinois, they created the smallest robot in the world.

On all axes, the size of this crab is 0.5mm. It has neither electricity nor hydraulics - all control is due to the laser, which heats the robot. And then, because of the shape memory material, it starts to move. The potential of such robots is huge - in medicine alone they can work wonders.

Mutual assistance.

If a goose gets sick or injured while flying and falls out of action, the other two goose follow to protect and help. They stay with the wounded goose until it can continue flying or dies.

Accuracy in everything!

Snow leopards wear their tail in their mouths so as not to get wet or dirty.

Folding house from Ten Fold Engineering.

Ten Fold Engineering has created a house that can fit in a container and unfold in 8 minutes. It is enough to find a fairly large area (the area of individual models can reach 200 sq.m.) and press the button. The house itself will be established to the final state. The design of the company's buildings takes into account all the necessary accessories, including bathrooms, bathrooms and kitchens.

Due to global warming, people are sleeping less

Experts studied 7 million sleep records from the bracelets of 47,000 adults from 68 countries. Global nighttime temperatures are rising faster than daytime temperatures. People all over the world cannot quickly adapt to this and begin to sleep less. The climate crisis is robbing us of 44 hours of sleep per year - that is, for 11 nights we sleep less than the required seven hours.

Fossils of two pterosaurs Thanatosdrakon amaru have been found in Argentina.

They died simultaneously 86-87 million years ago. The wingspan of one of them is seven meters, the second - nine. This makes it the largest flying pangolin ever discovered in South America. The discovered pterosaurs could be a parent and a calf - at the time of death they were nearby, while one of them was not yet an adult. But paleontologists have no proof of the degree of relationship.

In Hawaii, they began to make cocktail tubes from seaweed.

Loliware launched the production of seaweed cocktail straws. They replace plastic ones, keeping the coastline clean. The tubes are made like this: they dry, grind and mix the algae with a solution of natural dyes, and then give the resulting mass a shape. The technology is simple, cheap and competitive. Algae tubes are better than paper tubes: they do not get wet, they retain their shape and texture.

Money and power affect the amount of gray matter in the brain.

Socioeconomic status is associated with gray matter volume in the brain. Depending on the level of education and income, the prestige of work and place of residence, it varies within 1.6%. Low status in general negatively affects the brain. These conclusions were made by scientists from the University of Pennsylvania during the analysis of data from the British Biobank - it contains information about about 500 thousand people.

An eco-activist from Los Angeles put on his trash for a month to save the planet.

Rob Greenfield put the trash in the see-through pockets of his custom-tailored suit. At the end of the experiment, bags with disposable cups, napkins, cotton swabs, bottles and packages weighed about 28 kilograms. Rob, hung with garbage, walked around the city and its environs, demonstrating how much waste one person produces in just a month.
