What is a food compass according to American scientists?

As a rule, the characteristics of the product on the label are not enough to determine the extent of its effect on the body and health benefits. American scientists at Tufts University analyzed more than 8,000 foods, drinks and ready meals and made a kind of rating of their usefulness. The researchers tested the products for 54 characteristics and effects on the development of diseases: diabetes, cardiovascular disease and obesity. This information will help you write more detailed descriptions for labels, determine the nutritional value of a product, and make more informed food choices.

At the Rotterdam Zoo, visitors are given 'look at the ceiling' glasses.

After a gorilla broke out of its enclosure and attacked a woman at the Rotterdam Zoo, Holland, visitors were given glasses with eyes depicted on them, looking into the upper left corner. Glasses in the style of "look at the ceiling" are needed in order to avoid eye contact with primates, for which a direct look is a manifestation of aggression. And they see in these glasses through small holes located in the middle of the "lenses".

Most members of the cat family have retractable claws.

This allows you to maintain sharpness without grinding them when walking, and at the same time walk silently.

Asian giant hornet.

Asian giant hornets are the largest of the hornets, reaching four centimeters in length. Their stinger is so large that it can pierce through two layers of clothing, including a protective bee suit.

American scientists have created a wireless pacemaker that dissolves in the body after the expiration of its service life.

The device is 0.25 millimeters thick and weighs less than half a gram. It works without a battery. Power is supplied from an external antenna via near field coupling. Sensors on the skin monitor body temperature, oxygen levels, respiration, muscle tone, physical activity, and the electrical activity of the heart. Based on these data, the stimulation mode is calculated. Information can be sent to the application and forwarded to the attending physician.

Robots in New York have begun to help the elderly fight loneliness.

ElliQ, a robot that looks like a small tablet, is the ideal companion and psychologist for the elderly. On average, participants in the pilot interacted with the robot at least 20 times a day, according to a press release. And all the elderly people noted that he helps them a lot.

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.

Scientists have proven the benefits of living with a dog

It turned out that if a child aged 5-15 lives in a family with a dog, then he is more likely to have good intestinal permeability, a healthy microbial balance and a strong immune response, which helps protect against Crohn's disease. In families with cats, no such association was found.

Scientists have grown cartilage tissue in the shoulder joint of the robot.

It imitated the natural movements of a person, and this allowed the cells to grow and develop rapidly. Artificial cartilage can be used in medicine to model joints and tendons. During growth, it must be constantly stretched and bent. Previously, automatic devices that stretched the tissue were made right in the bioreactor, but in the end, real cartilage was still not obtained - strong and elastic. Scientists approached the problem in a different way. Instead of conventional devices, they used a robotic arm. The growing cartilage tissue was placed in an artificial shoulder for two weeks. The robot imitated human movements for half an hour a day. Under such conditions, the cells began to grow faster.

The new heart-safe dose of alcohol is 70 grams per week

Observations showed that moderate or high alcohol consumption increased the risk of heart failure by 4.5 times. No protective association was found in the low alcohol consumption group.

The world's first blood test for the diagnosis of Parkinson's disease has appeared.

The test is based on the P450 enzyme reaction. Its expression changes when any health problems develop. This affects the number and properties of certain metabolites. Scientists have found out what changes are characteristic of Parkinson's disease, and they reveal them. The accuracy of the test is 85-88%. Rapid diagnosis may allow the development of new treatments.

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.
