Over the past two centuries human life expectancy has increased by nearly 50 years. Genetic factors account for about one-third of the variation in life expectancy so that most of the interindividual variation in lifespan is explained by stochastic and environmental factors, including diet. In some model organisms, dietary (energy) restriction is a potent, and highly reproducible, means of incr...

5-Dimethyl­amino-N,N-dimethyl-2-nitro­benzamide

In the title compound, C(11)H(15)N(3)O(3), one of the methyl groups attached to the benzamide unit is slightly twisted with a C-N-C-C torsion angle of 4.04 (13)°. The crystal packing is stabilized by weak intermolecular C-H⋯O hydrogen bonds together with a weak C-H⋯π inter-action.

2,2-Dimethyl-5-triphenyl­methyl-1,3-dioxane

The title compound, C(25)H(26)O(2), crystallizes with two crystallographically independent mol-ecules in the asymmetric unit. The differences between the two mol-ecules are marginal. The three benzene rings of each mol-ecule are in a propeller orientation and the 1,3-dioxane ring adopts a chair conformation.
