11 minutes of daily walks will help to avoid early death.

Scientists have found that brisk walking for just 11 minutes a day reduces the risk of premature death by almost a quarter. These findings are based on the largest study of over 30 million people worldwide. Health experts recommend 150 minutes a week of moderate physical activity. However, even half that amount brought significant benefits, reducing the risk of cancer and cardiovascular disease by 7% and 17%, respectively.

For one sleepless night, your brain ages by 1-2 years - scientists have determined.

The experiment involved 134 people: their brain age was determined using MRI, starting from the volume of tissues and fluid. It turned out that one sleepless night causes changes in the brain, similar to those observed after a year or two of aging. But there is good news: enough good sleep, as the brain returns to its original state.

There was a brain implant that allows you to type text with the power of thought.

It has already been implanted by 7 people. The implant can help patients with paralysis or degenerative diseases. Its work is simple: the implant is brought to the cerebral cortex through the circulatory system, and the contacts are connected to the “prefix”, which turns thoughts into a digital signal.

Scientists have named a dietary supplement that can protect against dementia.

The dietary supplement nicotinamide riboside (NR) may protect the brain from neurodegenerative diseases such as Alzheimer's disease. HP stimulates the production of nicotinamide adenine dinucleotide (NAD+). It helps repair cells and damaged DNA and regulates redox processes. NAD+ levels decrease with age and, for example, due to obesity or smoking. The lead author of the study believes that the results indicate that HP slows down neurodegenerative processes. Further research is needed to prove this.

Vapes damage DNA even more than cigarettes.

This is stated in a new study from Nicotine & Tobacco Research. It turns out that vapers have 2.6 times more DNA damage than non-smokers, while regular smokers have 2.2 times more DNA damage. In addition, the sweeter the taste of the liquid, the more harm it does. Now scientists want to find out what diseases can cause these types of DNA damage.

The Japanese have created a useful toy that will help keep your posture while working at the table.

The principle is simple: the arms and legs of the toy are attached to the table, and the built-in core rests against it, preventing you from bending over.

In the USA, they decided to fight constipation with the help of vibrating capsules.

They do not contain active drugs. They force the intestines to empty, affecting nerve cells and causing muscle contractions. Capsules should be taken orally every day. They reach the large intestine in about 14 hours. After that, they start working. During the tests, the capsules were programmed for several vibration sessions - three seconds after three. The sessions lasted a couple of hours. The capsules were passed out of the body along with the faeces.

Good sleep prolongs life by several years.

Research has shown that men who sleep well regularly can live up to five years longer than those who don't, and women can live up to two years. They usually also enjoy better health throughout their lives. However, the quality of sleep is key. The scientists identified the following factors: an ideal duration of seven to eight hours a night, difficulty falling asleep and trouble sleeping no more than twice a week, no sleeping pills, and feeling good after waking up at least five days a week. More research is now needed to determine why men doubled their life expectancy compared to women who had the same quality sleep.

Skipping breakfast undermines the immune system.

Skipping breakfast constantly compromises the immune system and can increase the risk of cancer and heart disease. The researchers observed two groups of mice. The first was fed a hearty breakfast immediately after waking up. The second - gave only water. At the same time, immediately after the rise and after four and eight hours, blood was taken from the rodents for analysis. It turned out that fasting mice had a sharp drop in the levels of monocytes - white blood cells that help fight tumors, pathogens and inflammation. About 90% of these cells disappeared from the bloodstream of rodents as early as four hours after the missed breakfast. Four more years later, they were gone.

More than a billion people in the world can get cholera.

More than a billion people could become ill with cholera - last week three countries reported new outbreaks of infection, their total number rose to 22. According to a WHO representative, 50% more countries experienced cholera outbreaks last year than in 2021. This year, the disease threatens residents of 43 states. Cholera is a particularly dangerous infectious disease, its causative agent enters the human body along with contaminated food or water.

MIT has created a technology for printing a completely artificial heart.

But with one caveat. This heart is a complete copy of the patient's heart - the 3D printer receives information from the scan and reproduces the organ of a particular patient. And on it, surgeons can both train before operations and carry out the necessary diagnostic procedures without interfering with a living person.

The third person in the world has been cured of HIV thanks to a stem cell transplant.

German doctors reported the third case in the history of curing a person from HIV. The woman managed to recover thanks to a cord blood transplant - transplantation of stem cells from an unrelated newborn. The fact that a mixed-race woman was cured of HIV "marks a big step forward in drug development," the scientists said.

The brains of children have literally grown old during the pandemic.

By studying MRI scans of adolescents before and after the lockdown, Oxford scientists found signs of premature brain aging. The lockdown lasted less than a year, and the difference in brain age was 3 years. Due to the pandemic, many teenagers have experienced mental health problems - many have suffered from panic attacks and depression. These conditions led to physical changes in the organ.

Glaxo hid the truth for 40 years.

The British manufacturer hid the risk of developing cancer when taking the popular drug Zantac for 40 years. For the first time, studies confirming that the medicine for stomach ulcers and heartburn "Zantac" can cause the development of cancer appeared in 1978, when its release began. The manufacturer, the British pharmaceutical company Glaxo, withheld this information. The drug was the world's best-selling prescription drug. The company received an award from Queen Elizabeth II for its success. In 2019, it became known that the active substance of the drug, ranitidine, contains a carcinogen. After that, it was banned from sale.

Doctors have learned to diagnose covid by analyzing tears.

Brazilian scientists were able to diagnose coronavirus by analyzing tears collected with a cotton swab. The new method was tested on 61 patients. Some had covid, the other did not. In terms of accuracy, the test can replace a swab from the nasopharynx.

Scientists have found that purple fruits and vegetables may protect against diabetes.

Finnish researchers have found that red and purple fruits and vegetables contain pigments called anthocyanins that can prevent diabetes. Purple potatoes are especially beneficial for health. Anthocyanins may reduce the risk of diabetes by affecting metabolism, gut microbiota, and inflammation. This substance is found in abundance in purple potatoes, radishes, purple carrots, and red cabbage. Foods such as blueberries and mulberries contain mostly non-acylated anthocyanins. They are less digestible, but they have other important functions. For example, they improve gut health, suppress inflammation, and regulate glucose and lipid metabolism, which reduces the risk of developing diabetes.

A brain chip that gives "sight" to the blind.

Scientists from the Netherlands have created a chip that is implanted in the brain and works in conjunction with special glasses with a small camera. The camera transmits an image of the environment to a computer wearing glasses. It converts the image into a dot image using AI, and the chip receives this image wirelessly and projects it to the brain using electrical impulses.

Alzheimer's seems to be no longer a disease of the elderly.

In China, a 19-year-old boy who has been suffering from problems with concentration and memory has been officially diagnosed with the disease. He became the youngest carrier of Alzheimer's on the planet.

In honor of Keanu Reeves, a remedy for the fungus was named.

In Germany, scientists for the first time managed to isolate a natural substance that destroys pathogenic microorganisms and fungi. The group of molecules responsible for killing has been given the name "Kyanumycins". According to one of the authors, Sebastian Goetze, Keanu was chosen because in the movies he destroys his enemies just as quickly.

American scientists have learned to control HIV with a single injection.

They used the drug cabotegravir and injected it into a special subcutaneous implant. In this case, the drug is released gradually, ensuring a gradual and safe delivery of the drug to the blood. An experiment in macaques showed that one injection gave complete protection against the development of infection for five to six months. Further research should confirm the effectiveness of the technology for humans.
