Metformin regenerates the brain, but it only works on women, children and mice
In-depth analyzes of metformin showed a strong difference between the sexes: female specimens react better, on males it does not work.

Get back the view with corneal transplant from iPS
Corneal transplantation from induced pluripotent cells (iPS) on July 27, then course and discharge on August 23. The patient has already regained her sight.
Pinching, spray skin to repair wounds and burns
It's a new paradigm: doctors can abandon gauze and bandages, instantly acting directly on the skin to repair wounds and burns.
Synthetic meat, in vitro burger costs continue to fall
The time of the synthetic hamburger is approaching. Just two years ago I talked about it here, remember? The forecasts were of a probable entry into the market within 5 years: the main obstacle was the price. In 2013, making a kilo of “lab-created” meat cost around 620.000 euros. Two years later the price was 85 euros, and today it has dropped to 20 euros. Production costs are rapidly approaching those that warrant making their way into the market,… Read more
Gene therapy cures “bubble babies”
There is new hope for the so-called "bubble children", those children affected by ADA-SCID, a very serious and rare form of hereditary immunodeficiency that makes them easy prey to viruses and bacteria. There is a new treatment method, obtained by modifying patients' stem cells through the insertion of the gene responsible for the disease, revised and corrected. An achievement, called gene therapy, which will allow these children to live in the real world, outside the bubble that protects them day and night. Luigi Naldini, director … Read more
A study definitively proves that aging is reversible
A group of French scientists managed to restore the original functions of cells taken from over 1-year-old patients, reprogramming them and returning them to the stem cell stage: this is proof that the aging process can in fact be reversed. The research on the possibility of removing the signs left by cellular aging, published on November 2011, XNUMX in the journal Genes & Development, “opens up a new era of regenerative medicine,” declares Jean Marc Lemaitre, who directed the study at the Institute of … Read more
Synthetic hamburger: 5 years for sale
In 2013, research by Prof. Mark Post at Maastricht University in the Netherlands led to the development of a synthetic hamburger that takes 8 to 9 weeks to grow in the laboratory. With the same technologies as two years ago and more resources, even a million products can be created, and maintain a pace worthy of a fast food chain. This is meat "grown" in the laboratory starting from stem cells: the commercial prospect is incredible, because a product... Read more
All about the super job of the future
I often jokingly hear friends say that to get (or keep) a job today you need superpowers (the most sexist and boorish ones in the case of pretty colleagues argue the need for other skills). The future is made up of many things, and an important theme is precisely that of human enhancement, the improvement of physical and mental performance that can arise from the use of new technologies or medical procedures: in this article I want to offer you some ideas to reflect on. … Read more
You move on to artificial blood
Artificial blood could soon become a reality thanks to the first successful human transfusion. Dr. Luc Douay of the Parisian University 'Pierre et Marie Curie' extracted stem cells from bone marrow and 'encouraged' them to grow and transform into blood cells by administering a cocktail of growth factors: finally he injected 10 billion of these cells (the equivalent of 2 milliliters) in the donor's spinal cord. After 5 days 94% of the cells were still alive and… Read more
In nanomachine towards the future
It's not the first and it won't be the last. Scientists from the University of Groningen (Holland) and the Empa research center (Switzerland) have created a nanometric transport system equipped with four motor units (translation: a “namomachine”). It's electric, four nanometers long and every half turn of the wheels has to fill up... It works thanks to a scanning tunneling microscope positioned above it, which transmits a tiny electric charge that causes reversible structural changes in the wheels (translation: … Read more
Jobs of the near future: 26 jobs of tomorrow
In the days that mark the fall of the Berlusconi government and the Italian economic crisis (remember? we predicted it on the old site) I am as disheartened as all of you. The moment is difficult: we can only get out of it if all levels of our country change by looking to the future more than to the past. Some jobs will still survive in the future, let's be clear: but there is a whole series of jobs that don't exist today and which could be useful in the near future. Let's go with common sense: 60%...
