Rapamycin target and aging: new data

Scientists have linked the hyperactivity of the mechanistic target of rapamycin – the mTORC1 cellular pathway – with a decrease in ketone production, which is a physiological marker of aging in mice.

We are not only a little Neanderthals, but also a little Denisovans

Melanesians inhabiting the islands to the northeast of Australia received 4-6% of their genes from Denisovans. If we consider that the Neanderthals also left a trace in the genomes of modern humans, the total contribution of the "cousins" will be about 8%.

How to make a boy out of a girl and teach mice to sing?

Christmas gifts from genetic engineers: they turned a female mouse into a male by activating the SOX3 gene in the genitals of a developing embryo with two X chromosomes, and (quite by accident!) they bred a breed of singing mice.

"Zinc fingers" for gene modification – fast and inexpensive

Scientists from the University of Minnesota have collected an extensive archive of zinc fingers – nuclease enzymes necessary for manipulating genes. From their blocks, any scientist can easily get the zinc-containing nucleases he needs in less than a week.
