WHY do children resemble their parents?

Owing to the transfer of information stored in the nuclei of cells. The existence of discrete carriers of hereditary properties was discovered by the Austrian monk Gregor Mendel in 1865. He called them "hereditary germs". Yet his findings were ignored.

They were rediscovered only in the 1900s. Their material nature remained unclear until 1944, when it was discovered that the carrier of hereditary information is a molecule of deoxyribonucleic acid (DNA).

In 1953, a model of its structure was proposed, and soon the genetic code was deciphered. Now the genomes of many species, including humans, have been fully read. But how exactly this or that sequence of genetic "letters" determines the characteristics of organisms will be studied for a long time to come.

WHY are dark green vegetables considered so beneficial?

Dark green vegetables have high levels of lutein, which plays a major role in the physiology of vision and increases visual acuity and protects the retina, preventing gradual vision loss.

Spinach, kale, and parsley are considered the leaders in lutein.

👀In a major breakthrough in regenerative medicine, scientists have restored vision in patients using stem cells.

It offers new hope to millions.
A clinical trial in Japan in 2022 has successfully restored vision in multiple patients using a radical stem cell transplant. Researchers at Osaka University Hospital used induced pluripotent stem cells derived from healthy human blood cells to generate corneal epithelial cell sheets.
These sheets were transplanted onto the damaged corneas of four patients suffering from limbal stem cell deficiency (LSCD), a condition that causes scar tissue buildup and vision loss.
Two years after the procedure, the results show significant improvement, with three patients experiencing clearer vision and more transparent corneas. Unlike traditional transplants, this approach eliminates the need for donor corneas, offering hope to millions suffering from cornea-related blindness.
While the procedure remains experimental, it marks a major milestone in regenerative medicine.
Previous attempts at using stem cells focused on macular degeneration, but this is the first successful application for corneal restoration. Despite promising results, one patient experienced a decline in vision after a year, possibly due to an immune response. Researchers are now planning larger clinical trials to refine the technique and improve its long-term effectiveness.
If successful, this innovative treatment could revolutionize vision restoration, providing a sustainable and scalable alternative to corneal transplants for those in need.

WHY is it essential to soak nuts before consumption?

Soaking is a simple and effective way to get all the nutrients from nuts. When in contact with water, the kernel is saturated with moisture, which activates enzymes and changes its composition. It increases the number of vitamins and antioxidants.

And these substances become available to the human body, as phytic acid passes into the water during soaking. The removal of phytic acid improves the absorption of nut pulp in the intestines, prevents unpleasant consequences in the form of bloating and increased gas formation.

WHY are almonds healthy?

The consumption of just four almonds a day will help to reduce cholesterol levels, improve hair quality, prevent heart disease, fight wrinkles, overweight, and most importantly, improve brain function.

It is an excellent source of calcium, iron, magnesium, phosphorus and potassium. It contains many B vitamins (B1, B2, B3, B5, B6, B9), as well as tocopherol (vitamin E).

WHY are there many drugs against bacterial infections and few against viral ones?

A bacterium is an integral single-celled organism which biochemistry is quite different from that of humans. Therefore, it is possible to find drugs that block the enzymes vital for bacteria or destroy their cell wall, while being harmless or minimally toxic for humans.

A virus, on the other hand, is much simpler, and after infecting the target cell, it has nothing of its own except for the genome. Genome duplication and synthesis of viral proteins are performed by the same molecular mechanisms of the infected cell that ensure the vital activity of healthy cells.

WHY do the instructions for medicines demand that pills be swallowed with water?

Other drinks may contain substances that react with the contents of the pill or affect its physiological effects.

Even carbonated water without syrup changes the effect of some medicines by speeding up their absorption.

WHY not to wear lenses when you're sick?

When sneezing or coming into contact with your eyes, if you, say, touch your nose with your hand and then run your fingers over your face next to your eyes, bacteria can get on the surface of the lens. This multiplies the risk of eye infections many times over. A weakened immune system also worsens the situation. After all, a weakened body is more difficult to resist the emergence and development of new diseases.

Increased temperature leads to drying of the mucous membrane of the eye. The same effect occurs when taking certain medications, such as antihistamines used in allergies. A person feels itching and burning in the eyes, suffering from their redness. Contact lenses can aggravate this condition, so you can not wear them with a cold.

WHY is it beneficial to sleep during the day?

The point is that sleeping during the day prevents "burnout". It restores the body, reduces stress, and gives you the opportunity to rethink the situation.

Also daytime sleep reduces the risk of cardiovascular disease. Those who sleep in the afternoon at least 3 times a week, reduce the risk of heart disease by 40%.

Scientists claim that daytime sleep is a powerful weapon against myocardial infarction.

WHY does the heart run for a lifetime without tiring?

The secret is that the heart, although it works throughout a person's life, still "finds" time to rest. Our heart consists of two atria and two ventricles.

The fact is that the ventricles and atria never contract simultaneously - they always work in alternating shifts.

If we calculate the time during which the heart remains in a relaxed state, we get that it rests for approximately the same amount of time as it works.
