Swedish scientists have created a new cancer treatment strategy

Researchers have discovered the protein MTH1, which helps cancer cells to protect themselves from oxidative stress. They suggested using MTH1 inhibitors, which suppress its activity and deprive cancer cells of protection.

Dietary supplements for prolonging the life of the test did not stand up

In an article published last year, a cautious and competent biochemist claims that none of the most popular complexes, presented as "life-extending biological additives", actually prolongs the life of mice.

To prolong life, you need the right low-calorie diet

Calorie restriction still prolongs life and reduces the likelihood of age-related diseases in primates. At least this turned out to be true for several dozen Rhesus, which were observed for more than 20 years.
