Mechanics dictate where and how freshwater planarians fission SUMMARY: Planarians are tiny squishy worms that go through binary fission by ripping themselves in two parts: the head part and the tail part. This article looks at the mechanism of the ripping. First, there is the formation of the waist, then pulsation of the head, then… Continue reading Planarian Fission

Insights into transgenerational epigenetics from studies of ciliates
Insights into transgenerational epigenetics from studies of ciliates SUMMARY: This article summarizes what we know about ciliate epigenetics so far. The first section is an introduction to their weird nucleus situation: ciliates have two types of nuclei, the macronucleus and the micronucleus. Several examples of ciliate epigenetics are given in sections 2 and 3. Some… Continue reading Insights into transgenerational epigenetics from studies of ciliates
Rotifers Eating Foreign DNA
Evidence Supporting the Uptake and Genomic Incorporation of Environmental DNA in the “Ancient Asexual” Bdelloid Rotifer Philodina roseola SUMMARY: This study looked at whether bdelloid rotifers were better at taking in DNA compared to Monogononta rotifers. Bdelloids are a class of rotifers that only reproduce asexually. There has never been a male observed. Their cells… Continue reading Rotifers Eating Foreign DNA
