Genetic exchange discovered in anciently asexual rotifers

Evolutionary biologists at Skoltech have discovered recombination in bdelloid rotifers, microscopic freshwater invertebrates characterized by their presumed ancient asexuality. The existence of such anciently asexual groups calls into question the hypothesis that sexual reproduction is indispensable for the long-term evolutionary success of a species. However, the recent study published in Nature Communications provides evidence of recombination and genetic exchange in bdelloids.

Researchers deconstruct ancient Jewish parchment using multiple imaging techniques

A picture may be worth a thousand words, but capturing multiple images of an artifact across the electromagnetic spectrum can tell a rich story about the original creation and degradation of historical objects over time. Researchers recently demonstrated how this was possible using several complementary imaging techniques to non-invasively probe a Jewish parchment scroll. The results were published in the journal Frontiers in Materials.
