Liverwort scatters the subarctic tundra in vast dappling clusters of elephantine flaps of pale and palest green. A tundra is a biome where the tree growth is hindered by low temperatures and short growing seasons. Here the season is 100 days and the tundra begins at an entirely distinct level, the ecotone a clear mark where short crippled trees[1] as they are called give way entirely and absolutely, no gradual thinning, to where there are no trees, whatsoever.

But mosses. And Liverwort. Marchantia.

He’s back up on the feet and he’s being very cautious.  He gets a takedown, but is now dealing with a guillotine for a bit. He pops free. He was briefly in side control, but got up and went into the half guard. He is now in mount after a pass and looking to be real methodical. He is slowly crunching his opponent from side control.[2]

We humans have more bacterial cells (1014) inhabiting our body than our own cells (1013) [2],[3]. It has been stated that the key to understanding the human condition lies in understanding the human genome [4],[5]. But given our intimate relationship with microbes [6], researching the human genome is now understood to be a necessary though insufficient condition: sequencing the genomes of our own microbes would be necessary too. Also, to better understand the role of microbes in the biosphere, it would be necessary to undertake a genomic study of them as well.[3]

It was a chilling experience, being in the hinterlands of a subarctic seemingly sparsely populated, only to discover numerous traces of war, WWII in particular, as we strode and hiked across the immediate surrounds. Gentle mossy dips revealing themselves to be dug out bunkers with rusted remnants still embedded and scattered; evidence of POW encampments, a WW2 Junnker crash site and an exploded WWI munitions storage facility - barely rusted, heaps of wire cutters, vast diaspora of casings and even some live ammunition, as well as heaps of safety pins.

The liverworts (or marchantiophyta) are descendants of the earliest terrestrial plants. The group is characterised by morphological simplicity, and this seems to be matched by simple underlying genome structures. Liverworts show promise as new experimental systems after recent developments in transformation methods and genome characterisation.[5]

He is back to standing. He has the back and is going for the Rear Naked Coke. He does get the Rear Naked Choke, while the other two carry own. He is in half guard with no kimura threat now.

He is standing as his opponent plays guard. He is being very calm and periodically going into top half and then returning to his feet. He has head control and gets swept by a keylock as he goes for a takedown. He is fending off halfhearted leglock attempts.[6]

By providing the ability to examine the relationship of genome structure and function across many different species, these data have also opened up the fields of comparative genomics and of systems biology. Nevertheless, single organism genome studies have limits. First, technology limitations mean that an organism must first be clonally cultured to sequence its entire genome. However, only a small percentage of the microbes in nature can be cultured, which means that extant genomic data are highly biased and do not represent a true picture of the genomes of microbial species [10]–[12]. Second, very rarely do microbes live in single species communities: species interact both with each other and with their habitats, which may also include host organisms. Therefore, a clonal culture also fails to represent the true state of affairs in nature with respect to organism interaction, and the resulting population genomic variance and biological functions.[7]

In The Development of X-ray Analysis, Sir William Lawrence Bragg mentioned that he believed the field of crystallography was particularly welcoming to women because the techno-aesthetics of the molecular structures resembled textiles and household objects. Bragg was known to compare crystal formation to "curtains, wallpapers, mosaics, and roses."[8]

The relative simplicity of genetic networks in liverworts, combined with the growing set of genetic manipulation, culture and microscopy techniques, are set to make these lower plants major new systems for analysis and engineering.[9]

He is in mount after a fast pass to the left and is pressuring down in low mount. Looking to get a keylock going. He uses a burst of energy to try a pass, but he pulls him back to half guard, while yielding the flattened back. He gets bucked off and He is standing.[10]

New sequencing technologies and the drastic reduction in the cost of sequencing are helping us overcome these limits. We now have the ability to obtain genomic information directly from microbial communities in their natural habitats. Suddenly, instead of looking at a few species individually, we are able to study tens of thousands all together. Sequence data taken directly from the environment were dubbed the metagenome [13], and the study of sequence data directly from the environment—metagenomics [14].[11]

We rebuilt the crash event in our minds, visualising it's trajectory from a 13 year old witness account given to us by the now elderly man who houses that memory, and the expert opinion of the drone operators. Incorporations of metal and body, memory and remnant and, fresh evidence.

He moves to a back take/seatbelt control off the arm triangle position. They hit the ground after a guillotine attempt by him. He is besting from side control and he has a very deep Rear Naked Choke stuck in. He appears to be fighting it until the very last moment possible. Guillotine busted in and he is now working a mean guillotine from front headlock position. He lost the Rear Naked Choke.[13]

From these stories new shards were found, fresh, their placement in conciliation with our imaginings. We build model airplanes of Junnkers, enacted crashes, used toy drones and kites and found a quiet seriousness when burning the toy model on the crash site on a windy, rainy Sunday morning. Bodies exploded into nothing by their desperate payload.

In contrast, the sequences obtained from environmental genomic studies are fragmented. Each fragment was obviously sequenced from a specific species, but there can be many different species in a single sample, for most of which a full genome is not available. In many cases it is impossible to determine the true species of origin. The length of each fragment can be anywhere between 20 base pairs (bp) and 700 bp, depending on the sequencing method used.[15]

For these reasons, computational biologists have been developing new algorithms to analyze metagenomic data. These computational challenges are new and very exciting. We are entering an era akin to that of the first genomic revolution almost two decades ago. Whole organism genomics allows us to examine the evolution not only of single genes, but of whole transcriptional units, chromosomes, and cellular networks.[18]
