Oceans: particle fragmentation plays a major role in carbon sequestration
A French-British team has just discovered that a little known process regulates the capacity of oceans to sequester carbon dioxide (CO2). Photosynthesis performed by phytoplankton on the ocean's surface transforms atmospheric CO2 into organic particles, some of which later sink to its depths. However, approximately 70% of this particle flux is reduced between a depth of 100 and 1,000 metres. Here

Transcription factor AP2 controls cnidarian germ cell induction
Clonal animals do not sequester a germ line during embryogenesis. Instead, they have adult stem cells that contribute to somatic tissues or gametes. How germ fate is induced in these animals, and whether this process is related to bilaterian embryonic germline induction, is unknown. We show that transcription factor AP2 (Tfap2), a regulator of mammalian germ lines, acts to commit adult stem cells

Major role of particle fragmentation in regulating biological sequestration of CO2 by the oceans
A critical driver of the ocean carbon cycle is the downward flux of sinking organic particles, which acts to lower the atmospheric carbon dioxide concentration.

For decades, it has been hypothesized that the missing loss could b
