The ambitious plan to decode every complex species on Earth

Posted by in categories: biotech/medical, genetics

An ambitious effort to sequence the genome of every complex organism on Earth was officially launched on 1 November in London.

“Variation is the fount of all genetic knowledge,” says project member and evolutionary geneticist Jenny Graves of La Trobe University in Melbourne, Australia. “The more variation you have the better — so why not sequence everything?”

The Earth BioGenome Project aims to sequence the genomes of the roughly 1.5 million known animal, plant, protozoan and fungal species — collectively known as eukaryotes — worldwide over the next decade. The initiative is estimated to cost US$4.7 billion, although only a small proportion of that money has been committed so far.

Should genealogy data be used to solve crimes?

Posted by in categories: biotech/medical, genetics

New research shows how police could use forensic DNA to track down a suspect’s relatives in genealogy databases that store a different kind of genetic data—and that were never intended for use in police investigations.

In other words, if your sibling leaves DNA at a crime scene, it could lead detectives to your door. That suggests new investigative possibilities for police—and also new concerns about genetic privacy and whether authorities who use forensic DNA in creative ways might be overstepping their bounds, says Noah Rosenberg, a professor of biology at Stanford University and senior author of a study, which appears in Cell.

“The potential to link people’s genotypes across databases has been developing for some time. It is both of interest and concerning, depending on one’s point of view,” says Rosenberg, who is also a member of Stanford Bio-X.

Studies raise questions over how epigenetic information is inherited

Posted by in categories: biotech/medical, genetics, health

Evidence has been building in recent years that our diet, our habits or traumatic experiences can have consequences for the health of our children — and even our grandchildren. The explanation that has gained most currency for how this occurs is so-called ‘epigenetic inheritance’ — patterns of chemical ‘marks’ on or around our DNA that are hypothesised to be passed down the generations. But new research from the University of Cambridge suggests that this mechanism of non-genetic inheritance is likely to be very rare.

A second study, also from Cambridge, suggests, however, that one way that environmental effects are passed on may in fact be through molecules produced from the DNA known as RNA that are found in a father’s sperm.

The mechanism by which we inherit innate characteristics from our parents is well understood: we inherit half of our genes from our mother and half from our father. However, the mechanism whereby a ‘memory’ of the parent’s environment and behaviour might be passed down through the generations is not understood.

Technology and Culture: Our Accelerating Epigenetic Factor Driven Evolution

Posted by in categories: computing, genetics, particle physics, space, virtual reality

Memes are not just learned, they run deeper than that, they are part of our shared experience as human beings. This is how we communicate to each other through spoken, written, and body language; this is how we participate in customs, rituals and cultural traditions. Indeed, human civilization has always been a “cultured” virtual reality. We don’t often think of cultures as virtual realities, but there is no more apt descriptor for our widely diverse sociology and interpretations than the metaphor of the “virtual reality.” In truth, the virtual reality metaphor encompasses the entire human enterprise. We should realize that all our ideologies and religions, our belief systems and models of reality are our own personal operating systems — real to us but wry to someone else — each of us lives in a seemingly shared but simultaneously private virtual world.

In a Transhumanist Future, Everyday Could Be Halloween

Posted by in categories: bioengineering, biotech/medical, genetics, habitats, health, nanotechnology, transhumanism

In the spirit of Halloween, where ghouls, ghosts, and vampires walk among us, our perception of reality will soon transform as well, forever possessed by the specter of Transhumanism!


Last year, I wrote about how people could transform themselves into one of my favorite horror creatures—a real-life werewolf—using modern science and tech. This merely scratches the surface, however, in terms of how far an individual can go. In a Transhumanist future, you’ll be empowered to not only question the extent of your humanity but equally put those questions into action.

There Are More Tiger Types Than We Thought, New Genetic Analysis Reveals

Posted by in categories: biotech/medical, genetics

Tigers seem pretty straightforward: stripes, sharp claws, awe-inspiring grace wielded by hundreds of pounds of rippling muscle, fondness of sugary cereal, etc. But new research on the big cats’ DNA is the latest indication that underneath that striking orange and black pelage, not all tigers are the same. Scientists are now reporting that tigers are broken up into six distinct subspecies spread out across Asia.

In endangered species like tigers, pegging down the exact number of subspecies can be pretty important for conservation purposes. Being mindful of how the species is naturally divided up in the wild—and how populations may be evolving independently of one another—can allow conservationists to more effectively manage populations as cohesive units. Global tiger conservation has struggled with this since there’s been plenty of disagreement on how many subspecies even exist.
