# video | Created "breathing" analogue of the human lung

Scientists from Rice University used 3D printing technology to create a miniature analogue of the human lung. The artificial organ turned out to be quite tiny – no more than a coin, but as the Popular Mechanics portal notes, in the future this revolutionary model can have a serious impact on the development of transplantology and moving away from the shortage of organs needed for transplantation. Only in the United States alone, 114,000 people are waiting for their turn for the transplantation of certain organs. In addition, during organ transplantation, people have to take special medications that block the body's rejection of new transplanted organs. According to scientists, bio-printed organs will be able to solve both problems. “One of the main obstacles to creating an analogue of a functioning living tissue was the inability to print complex vascular systems, which in the body serve to transport blood, air, lymph and Continue Reading

Presented the world's first heart, printed on a 3D printer made from human fabrics

Scientists from all over the world are trying to use 3D printing technology to create artificial organs. If they can prove their safety, effectiveness and durability, in the future, mankind will be able to forget about the donation, and introduce artificial analogues into the bodies of people who need healthy organs. Previously, researchers from Switzerland managed to create a mechanical copy of the human heart, but it was printed from silicone. Since silicone can be rejected by the body, scientists should have created a heart from the natural tissues of a person — this they finally managed to do. So, at least, scientists from Tel-Aviv University claim – they used only human tissues to print a small heart, which would not be rejected by the body. The structure of an artificial organ includes the vessels necessary for its work, collagen protein to create connective tissue and various biological molecules. This Continue Reading

Electrical brain stimulation temporarily rejuvenates the human brain for 50 years

Electrical brain stimulation can alleviate the symptoms of depression, bring patients out of a vegetative state, and even reduce the effects of Parkinson's disease. Recently, a group of scientists from the University of Boston demonstrated a technique that is able to restore the working memory of 70-year-old people so that it starts working like that of 20-year-old young people. It is noteworthy that the technique does not require implantation of electrodes directly into the patient's brain – stimulation is carried out through the scalp. The group was determined to improve the working memory of older people from the very beginning, and acted under the guidance of neurobiologist Rob Reinhart. Special attention was paid to working memorywhich allows you to memorize the information that is needed when performing a particular task. For example, it turns on when a person recalls a list of products to buy, looks for car keys, or Continue Reading

Regenerative medicine: the path to human longevity. Are we close to this?

Lizards can grow whole limbs. Flatworms, starfish and sea cucumbers grow whole bodies. Sharks are constantly replacing lost teeth, often growing more than 20,000 teeth throughout their lives. How to transfer these practical superpowers to people? Answer: through advanced innovations of regenerative medicine. While big data and artificial intelligence are changing our practical medicine and inventing new methods of treatment, regenerative medicine is aimed at replacing and rejuvenating our physical body. Is it possible to renew all the organs of the human body? Currently, three regenerative technologies are being developed, which together should enable us to fully improve and even replace vital human organs: Recovery: stem cells, body regenerative engine Replacement: organ regeneration and bioprinting Rejuvenation: young blood and parabiosis Let's dive into the prospect of immortality. Renewal and stem cells: the regenerative engine of the body Stem cells are undecided cells that can transform into specialized cells — the Continue Reading

Human eggs are first grown in the laboratory.

Scientists from Edinburgh made a breakthrough in medicine: for the first time human eggs were grown under laboratory conditions. This achievement opens up new possibilities in the treatment of female infertility. A team of scientists from the University of Edinburgh (University of Edinburgh) announced an amazing breakthrough in the treatment of infertility. The development of human eggs has long been shrouded in mystery. Now, having grown eggs in the laboratory, scientists have had the opportunity to study them in more detail. Women are born with immature eggs that develop in the process of puberty. After many years of hard work, scientists have managed to "force" the eggs to mature outside the ovaries. Despite the overwhelming success, scientists are in no hurry to rejoice, because this method must be improved before clinical use. Edinburgh scientists reported that they managed to bring to maturation and readiness for further fertilization only 10% of Continue Reading
