“Interspecies communication” strategy between gut bacteria and mammalian hosts’ genes described

Funny how all this just somehow happens even though “ There seems to be no more design in the variability of organic beings and in the action of natural selection, than in the course which the wind blows. Everything in nature is the result of fixed laws’. If the “fixed laws” produce all this communication, they are clearly intelligence operating under the name “laws.” This is just not what laws do.

Cell biology Intelligent Design Origin Of Life

Life form’s environment so extreme is has never been cultivated in a laboratory

The more we know, the more insights we can have, sure. But it’s not always clear what specific things truly extreme life forms can tell us about the more common ones. Maybe the message is more general, that life forms try their hardest to survive every circumstance. But what is it they have that rocks don’t?

Researchers: Male Y chromosome not a genetic wasteland after all

The Y chromosome has been notoriously difficult to sequence due to repetitive elements. Junk, right? Now, researchers from the University of Rochester have found a way to sequence a large portion of the Y chromosome in the fruit fly Drosophila melanogaster—the most that the Y chromosome has been assembled in fruit flies. The research, published […]

Remarkable vid of a mouse embryo developing

This series of videos from McDole et al. shows the development of a mouse embryo, captured using adaptive light-sheet microscopy, and highlights cell division (part A), cell movements (part B) and tissue dynamics (parts C, D) during embryogenesis. Paper. McDole, K., Guignard, L., Amat, F., Berger, A., Malandain, G., Royer, L.A., Turaga, S.C., Branson, K., […]
