Immune system: defender or bloody rubble?

The State cannot bypass the state security system. It also exists in a living organism – this is the immune system, whose task is both to identify and destroy foreign elements that have penetrated into the body, and to eliminate their own subjects whose behavior deviates from the prescribed.

To prolong youth, train your brain

If the brain is not exercised, it will atrophy in the same way as unclaimed muscles. How to properly "pump up" intelligence?

Table tennis in a Petri dish

In an optoelectric "cup", single cells can be easily separated and grouped together and the movement of each of them can be controlled separately.

History of genomics. Part 2: DNA technologies

The improvement of sequencing technologies and even more so DNA adjustments will give rise to new social, ethical and philosophical problems. The development of DNA technologies is inevitable, and someday they will become available (if not mandatory) for everyone.

Is the brain out of order? Inhale the stem cells!

Stem cells can be used to treat Parkinson's and Alzheimer's diseases, to restore brain functions after a stroke. Perhaps someday the delivery of stem cells to the brain using nasal spray will become the norm.

The stem cell scandal

The leadership of CellCyte, trying to "skim the cream" from the hype around stem cells, in various ways created the false impression that the company was about to start clinical trials. Now CellCyte shares are worth less than 5 cents.

History of genomics. Part 1: Genomic projects

The story of how the first methods of reading genetic sequences appeared, what they were and how genomics moved from reading individual genes to reading complete genomes, including complete genomes of specific people.

Nanomedicine: apply, but check

The scientific community is fully aware of the risks of using nanoparticles in medicine. Nanomedical drugs, like all other medicines and medical materials, are strictly tested.

The human microbiome

Scientists from the American Institutes of Health (NIH) expect to read the genome of 400 of the approximately 2,000 species of microorganisms living in the human body by 2011 as part of the Human Microbiome project.

A genetically diverse brain

The cells from which the human brain is formed undergo genetic modifications during development. Perhaps this is how human individuality is ensured: even in identical twins, the brain is built from genetically dissimilar cells.

Crisis prolongs life

During the financial crisis, the mortality rate in developed countries is falling: people have less money for alcohol, tobacco and delicious, but harmful food, they sit without work and enjoy communicating with family and friends, drive less and get into accidents.

Genetically modified bacteria instead of a syringe with insulin

The beneficial bacteria modified by scientists secrete a protein that stimulates the synthesis of insulin in intestinal cells. Perhaps in the near future, "live yogurt" with such bacteria will become an alternative means for the treatment of diabetes.

Bioethics: fantasies on the topic

In 1971, in the book "Bioethics: a Bridge to the Future", American oncologist Van Rensselaer Potter wrote: "The science of survival should be not just a science, but a new wisdom that would combine the two most important and extremely necessary elements — biological knowledge and universal values. Based on this, I propose a term for its designation — bioethics..."

Fibroblasts will cure periodontal disease

With periodontal disease and periodontitis, gum tissue can break down and expose the roots of teeth. This process, called recession, is fraught with hypersensitivity of teeth to temperature and root caries, not to mention a purely cosmetic defect. Impressive results were shown by the method of non–surgical treatment of recession - the introduction of autologous (own) fibroblasts into the gum tissue.

Russian Russian gene Pool on the Russian Plain

Russian Russian Gene Pool on the Russian Plain and an article published in The American Journal of Human Genetics were the results of the research. These works showed the huge genetic diversity of the Russian people on the Y-chromosome.
