D.S. Moss produces an occasional podcast, titled The Adventures of Memento Mori, subtitled a cynic's guide for learning to live by remembering to die. He talks about his ideas in an interview with the Eternal Life Fan Club (website), which can be summarized as embracing life by accepting death. There are eight episodes in the Adventures of Memento Mori so far, covering Plan on Dying, Communicating with the Dead, The Science of Immortality, Past Life Regression, Escaping Death, Thoughts in Passing, and Digital Afterlife. Remember to Die is also on Twitter and Instagram, and I am Mori on YouTube. [more inside]

From deities to data - "For thousands of years humans believed that authority came from the gods. Then, during the modern era, humanism gradually shifted authority from deities to people... Now, a fresh shift is taking place. Just as divine authority was legitimised by religious mythologies, and human authority was legitimised by humanist ideologies, so high-tech gurus and Silicon Valley prophets are creating a new universal narrative that legitimises the authority of algorithms and Big Data."

Genes that do the same thing in a human and a mouse are generally related by common descent from an ancestral gene in the first mammal. So by comparing their sequence of DNA letters, genes can be arranged in evolutionary family trees, a property that enabled Dr. Martin and his colleagues to assign the six million genes to a much smaller number of gene families. Of these, only 355 met their criteria for having probably originated in Luca, the joint ancestor of bacteria and archaea.Meet Luca, the Ancestor of All Living Things [more inside]

In his follow-up to Sapiens, Yuval Noah Harari envisions what a 'useless class' of humans might look like as AI advances and spreads - "I'm aware that these kinds of forecasts have been around for at least 200 years, from the beginning of the Industrial Revolution, and they never came true so far. It's basically the boy who cried wolf, but in the original story of the boy who cried wolf, in the end, the wolf actually comes, and I think that is true this time." [more inside]

Rafinesque (previously) was not known for his social graces; as John Jeremiah Sullivan writes, Audubon is the "only person on record" as actually liking him. During their visit, though, Audubon fed Rafinesque descriptions of American creatures, including 11 species of fish that never really existed. Rafinesque duly jotted them down in his notebook and later proffered those descriptions as evidence of new species. For 50 or so years, those 11 fish remained in the scientific record as real species, despite their very unusual features, including bulletproof (!) scales. Turns out we missed another 17 species that Audubon threw in there for fun.
Rafinesque’s “absurd” botanical legacy, Gray wrote, amounted to little more than a “curious mass of nonsense.” Gray’s note wouldn’t be the last unkind obituary in the annals of taxonomy, nor would it be the worst. That’s because the rules dictating how taxonomists name and classify living things bind these scientists in a web of influence stretching far back into the 18th century. When an agent of chaos like Rafinesque enters the scene, that web can get sticky fast. In a field haunted by ghosts, someone has to reckon with the dead.

The classification of Illinois's state fossil, the Tully monster, has been a mystery since its discovery in 1958. But now a team at Yale has determined that it is a vertebrate ancestor of the lamprey, after studying over a thousand fossils and noticing the presence of a notochord, among other distinctively vertebratey features. The (paywalled) Nature paper is here.

Sexual harassment in science generally starts like this: A woman (she is a student, a technician, a professor) gets an email and notices that the subject line is a bit off: “I need to tell you,” or “my feelings.” The opening lines refer to the altered physical and mental state of the author: “It’s late and I can’t sleep” is a favorite, though “Maybe it’s the three glasses of cognac” is popular as well.
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]
Kept in the dark for 60 years, fruit flies begin to reveal their genetic adaptations. In 1954, seven years after their cousins returned from space, a colony of fruit flies was plunged into a darkness which would continue through 1500 generations right up till the present day. The results of this study shed considerable light on the role of genetic variation in physical adaptation. Spoiler: [more inside]

One of the most beautiful, amazing, and depressing things I’ve ever done is participate in a whale necropsy. This work helps us understand the patterns of whale mortality, and determine whether whale deaths are natural, or possibly man-made. This is important stuff. In fact, their work has helped guide changes in policy, especially when it comes to designing the shipping lanes that go into and out of San Francisco Bay. Their research helped establish new, longer, and narrower shipping lanes that reduced the chances of ships hitting, and often killing, whales. This work saved whales’ lives. [more inside]

Sure, we may be a little weird compared to our close relatives for not having a baculum (penis bone), and maybe that's the sort of thing you want to explain for whatever reason, but does human penis size and shape need a uniquely human story? Assuming it's correlated to the vagina like it probably is in many other species, then no it doesn't... unless the size and shape of the human vagina has an exceptional story. Does it? We wouldn't know. [more inside]
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]

“Cut Microbe” is a sculpture entirely hand cut out of paper. Measuring 44 inches/112cms in length, it is half a million times bigger than the ecoli bacteria upon which it is based. I wanted to create a sculpture that reflected in the process of being made the incredible scale and complexity of this microbiological world. I am amazed at the strange beauty of the natural world and wanted to open people’s eyes to aspects of it that they rarely see. -Rogan Brown
The world's coral is suddenly and rapidly starting to die - "This is only the third time we've seen what we would refer to as a global bleaching event. [The prior events] were in 1998 and 2010, and those were pretty much one year events. We're looking at a similar spatial scale of bleaching across the globe, but spanning across at least 2 years. So that means a lot of these corals are being put under really prolonged stress, or are being hit 2 years in a row."

It's well understood that many species of parasitic wasp, when they lay their eggs on host caterpillars, also inject viruses that prevent the host's immune system from attacking the eggs. But it was recently discovered that some of those virus genes, as well as genes from parasitic wasps themselves, have become a part of the genome of some lepidopteran species (even protecting these species from a different type of virus), thus demonstrating horizontal gene transfer between insect species (link to paper).
Last night, Virginia Tech grad student Ann Hilborn, her labmate Chris Rowe, and their research supervisor Marcella Kelly were posting pictures of animal genitals on their lab’s Twitter account (@Whapavt).

Since the pandas’ arrival, the team at Edinburgh zoo had already tried three times to breed the bears – with considerable fanfare and public attention – and each attempt had ended in disappointment. After a thoroughgoing review of these attempts in late 2014, this year’s season carried with it a sense of added pressure. But the keepers had also come up with one or two new tricks. A few weeks earlier, Maclean had daubed urine from Long Hui, an impressive male panda kept at Schönbrunn zoo, in Vienna, all over Yang Guang and Tian Tian’s enclosures, in order to spice the air with competition and possibility. “She spent a lot of time sniffing and seeing what was going on,” said Maclean. “He came out and was just like, ‘Whoa!’ He was all over the place.”
