Posture and breathing.

Poor posture, in particular stooping, prevents the lungs from fully expanding when inhaling, and less air enters them. In addition, with poor posture, the diaphragm - the main respiratory muscle - contracts and cannot move freely. This also reduces the amount of oxygen entering the body. The so-called vital capacity of the lungs also depends on the position of the head. When it is strongly tilted forward (protraction), the biomechanics of breathing changes, and lung capacity decreases by a third. All this means that insufficient oxygen enters the body - first of all, this will affect the functioning of the brain, and will manifest itself with symptoms such as fatigue, drowsiness, impaired concentration and memory.

Posture and spine.

Significant violations of posture further lead to diseases of the spine. Muscle imbalance resulting from pathological kyphosis or lordosis causes degenerative changes in the spine, leads to disc protrusions and subsequently the development of intervertebral hernias, leading to pain in its different parts. Pain in the lower back, neck, chest - very often a consequence of poor posture.

Benefits of walking.

Finnish scientists have proven that walking in the park reduces the need for medication by 3-4 times: for a visible effect, it is enough to walk through the greenery once a week for several hours. The result will be especially noticeable to people with asthma, mental disorders and diseases of the circulatory system.

Scientists have found a protein that helps repair and build muscle.

They found that the protein, which in humans is encoded by the PDGF-B gene, is constantly produced by skeletal muscle cells and helps repair muscle. The researchers hope that their discovery will help develop effective treatments for muscle wasting and injury, as well as improve training plans.

Trials of an implant for the treatment of depression.

The first implant to treat depression, Inner Cosmos, entered the second stage of human clinical trials. Once every 15 minutes, the device measures the levels of activity in the required part of the brain and stimulates them if necessary.

Biologists have suggested using spirulina algae as an alternative to beef.

Seaweed has almost the same nutritional value as beef. But growing it is easier and more environmentally friendly. It is even proposed to release it in the form of nutritional tablets.

A key breakthrough in the prevention of aging has been achieved.

A study appeared in the journal Cell about successfully influencing the epigenome, a function of our body that indicates whether a cell will become skin, brain, and so on. Scientists have reported that by playing with epigen, they managed to age the mouse on fast forward. And then, on the contrary, slow down some aspects of her aging.

American students have created a spoon that improves the taste of food.

A group of US students developed the Sugarware Spoon, which enhances the sweet taste without adding calories or chemicals. The cutlery has several convex parts on the underside that stimulate the taste buds that normally respond to sugar. They send signals to the brain that indicate the sensation of sweetness. It is not yet known whether the spoon will reach mass production. The creators believe that it will be especially useful for people with diabetes who are forced to diet.

Chinese scientists transplanted spinach particles into mice to teach them photosynthesis.

Biologists from Zhejiang University injected chloroplast particles from spinach into the cartilage of mice with osteoarthritis. This made it possible to restore the missing chemical compounds in the cells and cure the disease. They tested a fundamentally new way to treat joints and expect that this technology can be further optimized for the treatment of other diseases associated with changes in metabolism.

Engineers have created a glove for learning Braille.

The BrailleWear glove has a built-in electronic module with a small camera and a light. Light hits the printed braille dots at an oblique angle, causing each of them to cast a shadow. The software analyzes the received image and reads the text to the user using a synthetic voice system. The idea is that a person will eventually learn to recognize symbols by touch on their own. BrailleWear gloves should go on sale before the end of the year and will cost about $300.

Scientists have discovered a previously unknown protective layer of the brain.

Neurophysiologists from the UK and Denmark have found a hitherto unknown brain membrane. It is involved in the filtration of cerebrospinal fluid and serves as a "depot" for the accumulation of immune cells. The new shell was named SLYM - short for Subarachnoidal Lymphatic-like Membrane, "subarachnoid lymphatic-like membrane." The main studies were carried out on mice, but the presence of the membrane was confirmed in humans.

Tomorrow is a new day

Wake up as early as possible, exercise, have a good breakfast. The earlier you get out of your bed, the more things you can do throughout your day. If you are full of enthusiasm, ready to make your life full of positive events and things, create a rule for yourself to get up earlier than usual. A good and plentiful breakfast charges your battery for the whole day. Plentiful start allow you the opportunity to feel over the moon with happiness, because when you just woke up, your body is weakened, make it recharge. Jogging or push-ups from the floor will give you a boost of energy for the whole day.

Neuralink has launched a patient registry.

To learn more about specific diseases to improve brain implantation. People with medical conditions such as tetraplegia or tetraparesis, paraplegia, visual loss, deafness, and aphasia can apply. This application may enable future clinical trials with Neuralink. The company expects to start conducting human trials in the first half of 2023, but it all depends on the FDA approval process.

Withings U-Scan smart urine analyzer introduced.

He assesses the condition of the body and gives advice on improving health. The device is attached to the rim of the toilet bowl and, due to a special radar, is able to determine who is going to urinate. The results are transferred to a proprietary application. One cartridge is designed for 100 tests. In women, it even determines the menstrual cycle and the ovulation window.

Scientists managed to grow retinal cells that fuse with natural ones.

This is an insanely important study - they learned how to grow a retina from stem cells plus or minus ten years ago. However, until that time, scientists had problems with its implantation in specific people and the ability to turn from dummies into really working mechanisms. The day before yesterday, a study was published where scientists reported on the successful connection of the grown cells with all the inhabitants of the eyes. This is great news for people with some types of blindness.

Lack of interest in sex in men may indicate a risk of early death.

Scientists analyzed data on 20,969 people (8,558 men and 12,411 women) over 40 years old. For six years, they underwent regular medical examinations, and also assessed the level of their sexual interest. During the study, 503 subjects died. An analysis of the data obtained showed that mortality from cancer and other causes was significantly higher in men who were less interested in sex. This association persisted even when the researchers controlled for factors such as age, hypertension, diabetes, smoking, alcohol use, body mass index, education, marital status, and psychological stress levels.

Scientists have reported that cats and dogs help keep the human brain healthy.

Older people who have had cats or dogs older than 5 years perform better on cognitive tests than others. They also have better short-term and long-term memory. Now scientists are trying to prove what exactly causes such an effect on the human brain.

Korean startup Motion Pillow has unveiled a pillow that helps fight snoring.

The device automatically adjusts the position of the snorer's head until the unpleasant noise subsides. Price - $400, expensive, but what you wouldn't give for a quiet sleep.

The Italian company GAIT-TECH has created a smart insole.

It will redistribute the increased pressure of the weight along the entire foot. Italian shoe designer Diego Dolcini promises that the insole he developed will soften the impact of the ground when walking and redistribute weight pressure along the foot. The insole is made from recycled polymer to help relieve pain and prevent injury. It is built into the shoe at the manufacturing stage, so it is not felt when worn. The manufacturers promise that a pair of insoles will cost less than 20 euros, which makes it affordable.

The smell of chocolate helps to lose weight.

In the experiment, participants were asked to wear chocolate-scented T-shirts and imagine being served a bowl of ice cream. It turned out that those who felt the chocolate smell the longest wanted to eat sweets. This could probably be because the smell of something tasty unconsciously reminds people of their goal to eat less and makes them restrain themselves.
