"Anthropodermic bibliopegy, or books bound in human skin," writes Megan Rosenbloom in Lapham's Quarterly, "are some of the most mysterious and misunderstood books in the world’s libraries and museums. The historical reasons behind their creation vary [...] The best evidence most of these alleged skin books have ever had were rumors and perhaps a pencil-written note inside that said 'bound in human skin'...until now."

Dictyostelium discoideum - dicty to its friends - has long been recognized as the world's most fascinating slime mold. A (previously) has a good introduction from a decade ago. You might be fascinated by their life cycle, which goes from individual cells, to animal-like slug, to plant-like fruiting body. You might be fascinated by their starvation-prompted altruism, in which most cells give up their lives so that a few can reproduce, and cheaters are punished. You might be fascinated by the way they farm and protect their crops. (Or maybe the farmed bacteria are farming them; it's hard to tell.) Or you might be fascinated by a brand new study about the DNA nets they use to trap and kill pathogens.

In the wake of the sequencing of the human genome in the early 2000s, genome pioneers and social scientists alike called for an end to the use of race as a variable in genetic research. Unfortunately, by some measures, the use of race as a biological category has increased in the postgenomic age. Although inconsistent definition and use has been a chief problem with the race concept, it has historically been used as a taxonomic categorization based on common hereditary traits (such as skin color) to elucidate the relationship between our ancestry and our genes. We believe the use of biological concepts of race in human genetic research—so disputed and so mired in confusion—is problematic at best and harmful at worst. It is time for biologists to find a better way. - An editorial in Science exploring the conundrum facing genomic researchers where race is both fundamentally flawed as a scientific model and violently dangerous but still the only consistent lens through which study participants understand the information they have about their own connection to human diversity [more inside]
"Oh Ancient Ocean!/You are nothing!/Vast you may be!/Next to me what are you?/I am beautiful pink and you are stinky green!" In 1980, members of No Wave bands Mars and DNA recorded John Gavanti. An operetta loosely based on Don Giovanni, it's the story of a man with magical powers and a strong libido who gets it on with a lioness and a grandmother "in the beautiful autumn of life," among others. It was recorded in an all-vaccuum-tube-equipment studio that Sonic Youth later used to record 1987's Sister. Glenn Kenny at Trouser Press said "Some have called this the most unlistenable record ever made, and that's a fine invitation indeed." There's a review of sorts here. There's an unreadable fake(?) interview with fans and musicians here.
Humans 2.0 - "With CRISPR, scientists can change, delete, and replace genes in any animal, including us. Working mostly with mice, researchers have already deployed the tool to correct the genetic errors responsible for sickle-cell anemia, muscular dystrophy, and the fundamental defect associated with cystic fibrosis. One group has replaced a mutation that causes cataracts; another has destroyed receptors that H.I.V. uses to infiltrate our immune system." [more inside]

The Human Virome's Permanent Mark
The virome doesn’t get as much love as its charismatic older brother, the microbiome. Studies of the bacteria that live inside us have caught the public imagination, showing that we contain a teeming diversity of critters whose populations affect everything from our diets to our immune systems. Thanks to cheap DNA sequencing, you can send samples of your microbiome to a lab and have a quick census taken; services like American Gut will even give you a colorful chart showing you which bacteria have been found and in what numbers. (Strictly the virome is part of the microbiome, which includes all the viruses, protozoa, and fungi living in one environment ― but bacteria are the stars of the show.)[more inside]

Warren G. Harding is known for many things. Teapot Dome, dying in office (or maybe not), having the middle name "Gamaliel", and consistently being ranked one of the worst Presidents ever. His personal life was little better than his presidential one, with allegations of multiple affairs and even one claim of an illegitimate child born just a couple of years before he was elected to the White House. Which, according to DNA testing, is totally true. [more inside]
Since it folds in three dimensions, we could store all of the world’s current data—everyone’s photos, every Facebook status update, all of Wikipedia, everything—using less than an ounce of DNA. And, with its propensity to replicate given the right conditions, millions of copies of DNA can be made in the lab in just a few hours. Such favorable traits make DNA an ideal candidate for storing lots of informations, for a long time, in a small space.But how stable is DNA? The Reed-Solomon method, long used to error-check data transmission and duplication, is now being explored as an adjunct to the long-term archiving of information encoded in DNA. A post by Alex Riley at the PBS Science blog NOVA/NEXT.
In 2012 the genetics company 23andme gave web app developers the ability to create app mashups with DNA information.

Kennewick Man - or the Ancient One - has a contentious history (previously and previouslier) that inspired a long legal and moral battle between scientists who said he probably wasn't Native American and wanted to study him, and local tribes who insisted that he was an ancestor and wanted to re-bury him. The scientists won in court in 2005, and a study has now determined from DNA evidence that Kennewick Man "was most closely related to DNA from the Confederated Tribes of the Colville Reservation, one of the five tribes who originally claimed Kennewick Man as an ancestor."
DNA carries traces of past events meaning poor lifestyle can affect future generations Between week two and week nine of an embryo’s development the genetic code is being rewritten to erase genetic alterations from the parents. However the researchers found that the processes does not clear all of the changes. Around 5 per cent of DNA appears resistant to reprogramming.
Carl Zimmer writes for The New York Times: How Simple Can Life Get? It's Complicated - "Scientists have long wondered how much further life can be stripped down and still remain alive.

The CRISPR Revolution [ungated: 1,2,3] - "Biologists continue to hone their tools for deleting, replacing or otherwise editing DNA and a strategy called CRISPR has quickly become one of the most popular ways to do genome engineering. Utilizing a modified bacterial protein and a RNA that guides it to a specific DNA sequence, the CRISPR system provides unprecedented control over genes in many species, including perhaps humans. This control has allowed many new types of experiments, but also raised questions about what CRISPR can enable." [more inside]

"Scientists have reconstructed the genome of a man who lived 45,000 years ago, by far the oldest genetic record ever obtained from modern humans. The research, published on Wednesday in the journal Nature, provided new clues to the expansion of modern humans from Africa about 60,000 years ago, when they moved into Europe and Asia. And the genome, extracted from a fossil thighbone found in Siberia, added strong support to a provocative hypothesis: Early humans interbred with Neanderthals."

Much easier to put together custom DNA An interdisciplinary study led by Dr Ali Tavassoli, a Reader in chemical biology at the University of Southampton, has shown for the first time that 'click chemistry' can be used to assemble DNA that is functional in human cells, which paves the way for a purely chemical method for gene synthesis. Writing in Angewandte Chemie International Edition Dr Tavassoli's team and his collaborators, Dr Jeremy Blaydes and Professor Tom Brown, show that human cells can still read through strands of DNA correctly despite being stitched together using a linker not found in nature.

Epigenetics (prev) is the study of changes in gene expression or cellular phenotype, caused by mechanisms other than changes in the underlying DNA sequence. David Epstein, a senior writer for Sports Illustrated has written about this topic for his book The Sports Gene (not as reductive as the title might suggest), but cut the chapter because the material he researched was so new as to require that he "caveat the writing rather heavily." Instead, he shared his chapter How an 1836 Famine Altered the Genes of Children Born Decades Later on IO9. You can read or hear more about the book in a half-hour segment from NPR's Fresh Air, opening with a story of Jennie Finch, a softball pitcher who "just whiff[ed] the best hitters in the world."

The Hidden Life Of the Cell (57:24) There is a battle playing out inside your body right now. It started billions of years ago and it is still being fought in every one of us every minute of every day. It is the story of a viral infection - the battle for the cell. This film reveals the exquisite machinery of the human cell system from within the inner world of the cell itself - from the frenetic membrane surface that acts as a security system for everything passing in and out of the cell, the dynamic highways that transport cargo across the cell and the remarkable turbines that power the whole cellular world to the amazing nucleus housing DNA and the construction of thousands of different proteins all with unique tasks. The virus intends to commandeer this system to one selfish end: to make more viruses. And they will stop at nothing to achieve their goal. Exploring the very latest ideas about the evolution of life on earth and the bio-chemical processes at the heart of every one of us, and revealing a world smaller than it is possible to comprehend, in a story large enough to fill the biggest imaginations.
