Can laboratory evolution experiments teach us about natural populations?

What can selection experiments teach us about fisheries - induced evolution ?

What does Arabidopsis natural variation teach us (and does not teach us) about adaptation in plants?

Sessile organisms such as plants have to develop adaptive responses to face environmental change. In Arabidopsis thaliana populations, natural variation for stress responses have been observed at different levels of integration and the genetic bases of those variations have been analysed using two strategies: classical linkage and association (LD) mapping. The strength of Arabidopsis resides in...

Can Osler teach us about 21st-century medical ethics?

What can spermatogonial transplants teach us about male reproductive biology?

In this issue of Endocrinology, there is a rapid communication by Mahato et al. (1) that addresses the issue of estrogen action directly on germinal cells in the testis. The authors transplanted germ cells from the testis of the estrogen receptor a (ERa) knockout mice into the seminiferous tubules of germ cell-depleted wild-type mice. The germ cells carrying the knockout mutation underwent qual...

What atomic liquids can teach us about quark liquids

Over the last ten years there has been truly remarkable progress in the study of cold, dilute gases of fermionic atoms in which the scattering length a of the atoms can be controlled experimentally. These systems can be realized in the laboratory using Feshbach resonances, see1) for a review. A small negative scattering length corresponds to a weak attractive interaction between the atoms. This...
