The ability to create synthetic organs has long been desired in medicine. If we could make synthetic organs for patients from their own cells, we could replace injured or damaged organs without risking the body rejecting the organ. This would have huge implications for the treatment of liver and kidney diseases, among others. For years, scientists have tried to perfect this technology but have been unable to solve the blood flow problem that has made the creation of synthetic organs impossible.
In the last few weeks, a group of scientists appear to have found the solution to this problem or, at least, a major part of it [1].
We’re continuing to release talks from Ending Age-Related Diseases 2019, our highly successful two-day conference that featured talks from leading researchers and investors, bringing them together to discuss the future of aging and rejuvenation biotechnology.
In his talk, Reason of Repair Biotechnologies addressed the reasons why rejuvenation biotechnology is not proceeding as fast as it could be and discussed the ways in which his company is helping to expedite its development and release.
The human brain needs a continual supply of fuel. When this continual supply is interrupted brain cells begin to die. In the short-term, this can cause symptoms such as headaches, brain fog, & tiredness. Long-term exposure to environments that deplete sources of brain fuel from effectively getting into the cells leads to neurodegenerative diseases.
Researchers at Chalmers University of Technology, Sweden, have disproved the prevailing theory of how DNA binds itself. It is not, as is generally believed, hydrogen bonds which bind together the two sides of the DNA structure. Instead, water is the key. The discovery opens doors for new understanding in research in medicine and life sciences. The findings are published in PNAS.
DNA is constructed of two strands consisting of sugar molecules and phosphate groups. Between these two strands are nitrogen bases, the compounds that make up genes, with hydrogen bonds between them. Until now, it was commonly thought that those hydrogen bonds held the two strands together.
But now, researchers from Chalmers University of Technology show that the secret to DNA’s helical structure may be that the molecules have a hydrophobic interior, in an environment consisting mainly of water. The environment is therefore hydrophilic, while the DNA molecules’ nitrogen bases are hydrophobic, pushing away the surrounding water. When hydrophobic units are in a hydrophilic environment, they group together to minimize their exposure to the water.

Now 44, he has become the first patient to undergo a new life-changing eye surgery on the NHS, with doctors using stem cells from his healthy left eye to grow tissue in a lab and restore his sight.
Mr O’Brien said: “Being able to see through both eyes after all these years means the world to me.”
Researchers at the University of Helsinki in collaboration with researchers from Åbo Akademi University (Finland) and Huazhong University of Science and Technology (China) have developed a new anti-cancer nanomedicine for targeted cancer chemotherapy. This new nano-tool provides a new approach to use cell-based nanomedicines for efficient cancer chemotherapy.
You have to admit it. Some of the uses of artificial intelligence are simply fascinating. One of the more exciting aspects of artificial intelligence is seeing all the potential ways the technology can be applied to our daily lives, even if it at times it seems a little creepy. We have seen artificial intelligence technology shape everything from the medical world to art. However, did you ever think that AI would go on to shape the world of stock images?

Now if you are familiar with people using AI to create portraits of people who do not exist, then surely this idea came to your mind at some point. Yet, another industry influenced by the world of AI.
