Self-sustaining obesity

The accumulation of excess adipose tissue in the human body leads to the synthesis of a specific protein that suppresses the fat burning process. In other words, the accumulation of fat leads to the fact that it becomes harder to "burn".

The end of a beautiful era

Despite the apparent diversity of approaches, there is no decent alternative to antibiotics and is not expected in the near future. This means that we will continue to live with anibiotic resistance. And it should be taken very seriously.
