Radiation damage to paternal DNA is passed on to offspring: Study

Whether radiation exposure of fathers can have consequences on their children is one of the most long-standing questions in radiation biology. Using the nematode Caenorhabditis elegans as a model, Professor Dr. Björn Schumacher ...

Molecular puzzle reveals unknown stages of fetal development

By applying gene analysis to individual cells from early mouse embryos, researchers at Karolinska Institutet in Sweden have discovered previously unknown cellular stages of fetal development from fertilised egg to living ...

Parental chromosomes kept apart during embryo's first division

It was long thought that during an embryo's first cell division, one spindle is responsible for segregating the embryo's chromosomes into two cells. EMBL scientists now show that there are actually two spindles, one for each ...

Frogs reveal mechanism that determines viability of hybrids

Why are some hybrids viable and others not? It is known that this depends on the father species and the mother species. New research in two related frog species shows the influence of mother and father species: One hybrid ...

Human evolution has become multi-colored

Thus far, a tiny finger bone and two back teeth in a cave in the Altai Mountains are the only known remains of the Denisovans – a humanoid that Max Planck researchers have identified solely through their genetic material. ...
