So it seems that we should expect full genome sequences to be quite cheap within the next several years, if this trend is anything to go by. I think it’s time to start thinking about what effect this might have on health insurance.
Is a genetic disposition toward risk or alcoholism or cancer a pre-existing condition? Should it be treated as such? For what might a sequence be legally requested?
As far as things like personal medicine and gene therapy and the like go, the rapid decrease in sequencing cost is a big step forward. It also exposes an extremely private part of us, one that we shouldn’t want to be disseminated to government or corporations without a clear set of rules.
This is “what existed before the Big Bang?”, but don’t miss the rest at the link above.
Gooood morning everybody
More than a little disconcerting, especially considering Russell’s vipers are of the genus Daboia, which means the lurker and that lies hid(den), and enjoy living in high-density human populations.
On the plus side, at least it’s not among the dozens of poisonous animals trying to take over Australia!

HELP THIS IS GREAT
Nothing proves science is awesome by demonstrating it! I think we can all agree that science demonstrations like these in public areas would make them much more enjoyable.
Sort of like these Seattle street corners!
At the age of 15, Prof Sir John Gurdon ranked last out of the 250 boys in his Eton year group at biology, and was in the bottom set in every other science subject.
Sixty-four years later he has been recognised as one of the finest minds of his generation after being awarded the £750,000 annual prize, which he shares with Japanese stem cell researcher Shinya Yamanaka.
Speaking after learning of his award in London on Monday, Sir John revealed that his school report still sits above his desk at the Gurdon Institute in Cambridge, which is named in his honour.
my mom always said grades are important, but they’re not the most important thing.
I love how he framed that. He probably looked at it every day and said, “Oh yeah?”
Grades are poor measures of one’s potential to be curious.
We’ve seen slime molds “chase” their dinner, and we’ve seen them recreate the Tokyo rail system (whoa!) by maximizing efficiency in growth … now the ability to “map” their surroundings without “mapping”?
Brainless Slime Molds Shed Light On The Evolution of Memory
“We have shown for the first time that a single-celled organism with no brain uses an external spatial memory to navigate through a complex environment,” said Christopher Reid from the University’s School of Biological Sciences.
…“Results from insect studies, for example ants leaving pheromone trails, have already challenged the assumption that navigation requires learning or a sophisticated spatial awareness. We’ve now gone one better and shown that even an organism without a nervous system can navigate a complex environment, with the help of externalized memory.”
The research method was inspired by robots designed to respond only to feedback from their immediate environment to navigate obstacles and avoid becoming trapped. This “reactive navigation” method allows robots to navigate without a programmed map or the ability to build one and slime molds use the same process.
When it is foraging, the slime mold avoids areas that it has already “slimed,” suggesting it can sense extracellular slime upon contact and will recognize and avoid areas it has already explored.
…“We then upped the ante for the slime molds by challenging them with the U-shaped trap problem to test their navigational ability in a more complex situation than foraging. We found that, as we had predicted, its success was greatly dependent on being able to apply its external spatial memory to navigate its way out of the trap.”
