The world’s oldest practicing doctor, Dr Howard Tucker, has revealed his lust for life — and you won’t believe what he has to say.

Manipulating senescent cells by eliminating them or by modifying their activity has attracted huge interest for its potential to delay or even treat many age-related diseases, and to improve healthy aging. Mitochondria, and in particular their calcium levels, have emerged as key regulators of cellular senescence, cell death and the balance between the two, and might constitute targets for novel strategies to stifle the viability or properties of senescent cells.

Scientists combine two cancer drugs to delay aging and disease in mice.

Scientists in Europe have tested an anti-aging drug cocktail in mice and found that it extended the animals’ lifespans by around 30 percent. The mice stayed healthier for longer too, with less chronic inflammation and delayed cancer onset.

The two drugs are rapamycin and trametinib, which are both used to treat different types of cancer. Rapamycin is also often used to prevent organ rejection, and has shown promise in extending lifespans in animal tests. Trametinib, meanwhile, has been shown to extend the lifespan of fruit flies, but whether that worked in larger animals remained to be seen.

So for a new study, a research team led by scientists from the Max Planck Institute in Germany investigated how both drugs, on their own and together, could extend lifespan in mice.
