It really does seem to be a pretty universal law:
On the role of GRBs on life extinction in the Universe
As a copious source of gamma-rays, a nearby Galactic Gamma-Ray Burst (GRB) can be a threat to life. Using recent determinations of the rate of GRBs, their luminosity function and properties of their host galaxies, we estimate the probability that a life-threatening (lethal) GRB would take place. Amongst the different kinds of GRBs, long ones are most dangerous. There is a very good chance (but no certainty) that at least one lethal GRB took place during the past 5 Gyr close enough to Earth as to significantly damage life. There is a 50% chance that such a lethal GRB took place during the last 500 Myr causing one of the major mass extinction events. Assuming that a similar level of radiation would be lethal to life on other exoplanets hosting life, we explore the potential effects of GRBs to life elsewhere in the Galaxy and the Universe.
What that means is summed up in this article. Here’s the conclusion:
Astronomers have long known that the Earth occupies a unique position in the solar system that allows life to flourish. This idea of a habitable zone now allows them to focus search for exoplanets that might also have conditions that are right for life. Now they can take this further by excluding inhospitable regions of the galaxy, and searching only those stars and galaxies that exist in the universe’s habitable zones.
Of course, that’s just for life as we know it …

Since this blog has recently picked up a bunch of additional followers, I’m going to reiterate something I’ve said in the past: I’m mildly bipolar. Have been all my adult life. My ‘natural’ bipolar cycle is about 18 months, though that can be influenced by outside factors. It’s mild enough that I’m able to manage my bipolar swings without medication, but I keep a close eye on it. I’m thankful that I can manage it without medication, because I have always perceived a connection between this bipolar condition and creativity.
And increasingly, science agrees with me:
Professor Steven Jones, co-director of Lancaster University’s Spectrum Centre, said, “It appears that the types of inspiration most related to bipolar vulnerability are those which are self-generated and linked with strong drive for success.
“Understanding more about inspiration is important because it is a key aspect of creativity which is highly associated with mental health problems, in particular bipolar disorder.”
“People with bipolar disorder highly value creativity as a positive aspect of their condition. This is relevant to clinicians, as people with bipolar disorder may be unwilling to engage with treatments and therapies which compromise their creativity.”
Bingo.
And then there’s this, from an article on apophenia:
Another possible culprit in apophenia is dopamine. A 2002 experiment revealed that people with high levels of dopamine more often extract meaning from coincidences than those with lower dopamine levels. And when self-described skeptics (team “UFOs are fake”) were given the drug L-dopa, which ups the brain’s dopamine supply, they began to perform more like self-described believers (team “I can speak to spirits”) on the same pattern-finding tasks. Likewise, when Brugger and his colleagues administered dopamine to a group of healthy adult men, that group proved more likely than a control group to notice visual similarities between random pairs of shapes.
Personal accounts from manic patients fizz with an almost compulsive meaning-making, but the research on connections between apophenia and bipolar disorder is thin. One clue: Just like people with schizotypal tendencies, people at risk for bipolar disorder often ace creativity tests. They seem to excel especially at the type of “intuitive, open-minded thinking” that results in surprising associations. (Though he hasn’t studied apophenia and bipolar disorder, Brugger says he would “assume that you see connections everywhere in a manic state.”) A symptom of mania known as clanging, in which ideas are strung together not in a logical order but because of how the words sound, has an apophenic aura.
Related, this news about another scientific discovery concerning depression:
The first blood test to diagnose major depression in adults has been developed by Northwestern Medicine scientists, a breakthrough approach that provides the first objective, scientific diagnosis for depression. The test identifies depression by measuring the levels of nine RNA blood markers. RNA molecules are the messengers that interpret the DNA genetic code and carry out its instructions.
* * *
“This clearly indicates that you can have a blood-based laboratory test for depression, providing a scientific diagnosis in the same way someone is diagnosed with high blood pressure or high cholesterol,” said Eva Redei, who developed the test and is a professor of psychiatry and behavioral sciences at Northwestern University Feinberg School of Medicine. “This test brings mental health diagnosis into the 21st century and offers the first personalized medicine approach to people suffering from depression.”
I suspect that it won’t be long until some similar test is developed for markers indicating bipolar condition.
Oops, there I go, drawing connections again …

Another interesting item about developing the technology to create a useful swarm of small robots:
Harvard Researchers Create a Nature-Inspired Robotic Swarm
Some scientists believe that the way to solve the flocking enigma is to replicate it. Researchers at Harvard University’s Wyss Institute and School of Engineering and Applied Sciences (SEAS) recently developed a micro-scaled robotic technology that enables a controlled, flash mob–like assembly. In August, the team led by Harvard computer-science professors Radhika Nagpal and Fred Kavli demonstrated the ability of 1,000 robots to self-organize into user-selected shapes, such as a five-pointed starfish and the letter K.
* * *
“Increasingly, we’re going to see large numbers of robots working together, whether it’s hundreds of robots cooperating to achieve environmental cleanup or a quick disaster response, or millions of self-driving cars on our highways,” Nagpal said in the press release. “Understanding how to design ‘good’ systems at that scale will be critical.”
One provocative concept is the possibility of building and infrastructure construction that is carried out by thousands of self-organizing modules. Although many technical hurdles remain, this notion is especially intriguing in the case of hazardous and other challenging settings. In the near term, we will likely witness simple, one-story pavilions built from a collection of mobile robotic bricks to create emergency relief shelters following natural disasters.
Hmm … seems I’ve heard about that idea before someplace. Oh, yeah, from Communion of Dreams:
They were, in essence, enclosing the entire planet in a greenhouse of glass fabric and golden plasteel. It was going to take generations to finish, even using mass microbots and fabricating the construction materials from the Martian sands. Tens of thousands of the specially programmed microbots, a few centimeters long and a couple wide, would swarm an area, a carpet of shifting, building insects. As each cell was finished, it was sealed, joined to the adjacent cells, and then the microbots would move on.
But it is pretty cool to see the work being done to bring that about.

No doubt by now you’ve heard of the discovery of Dreadnoughtus schrani, the massive dinosaur found in the Patagonia region of Argentina (been there!), which in addition to being notable for its size is also notable for how much of it was found:
Lacovara says those other estimates are based on a mere smattering of bones, or on analyses that haven’t yet been subjected to peer review. In contrast, the estimate of Dreadnoughtus’ size and weight was based on measurements of more than 100 separate elements, including most of the tail vertebrae, a yard-long (meter-long) neck vertebra, numerous ribs and nearly all the bones from the forelimbs and hindlimbs.
Researchers unearthed about 45 percent of the skeleton’s full complement of bones, representing 70 percent of the bone types found below the skull (for example, a left rib without the mirror-image right rib).
Very impressive to find so much of it. Too bad they didn’t find the skull, as well.
Wait, no skull?
Hmm …
Yeah, I’m sure that it’s just a coincidence …

Yeah, it’s cool and all, but I can’t be the only one who looked at the news about Google X’s Drone Program …
A zipping comes across the sky.
A man named Neil Parfitt is standing in a field on a cattle ranch outside Warwick, Australia. A white vehicle appears above the trees, a tiny plane a bit bigger than a seagull. It glides towards Parfitt, pitches upwards to a vertical position, and hovers near him, a couple hundred feet in the air. From its belly, a package comes tumbling downward, connected by a thin line to the vehicle itself. Right before the delivery hits the ground, it slows, hitting the earth with a tap.
… and thinks “generation 1.0 Hunter-seeker“, right? I mean, this basically jumps from needing a large military drone to having a backpack assassination tool. Why worry about collateral damage with a missile when you can just drop a cigarette-pack lump of high explosive in someone’s lap, using a cell phone and facial-recognition software to make sure of your specific target?
Or how I look at the self-driving car and think “hmm, add a Ma Deuce and/or 30mm cannon, and you’ve a small autonomous tank”.
Yeah, OK, perhaps I’m just too cynical. But human nature being what it is, you’ve gotta think that there was a reason why DARPA has been behind the development of these technologies …

News item on NPR this afternoon:
Ebola In The Skies? How The Virus Made It To West Africa
The Ebola outbreak in West Africa is the most explosive in history. One reason the virus spread so fast is that West Africa was blindsided. Ebola had never erupted in people anywhere close to West Africa before.
The type of Ebola causing the outbreak — called Zaire — is the deadliest strain. Until this year, it had been seen only in Central Africa, about 2,500 miles away. That’s about the distance between Boston and San Francisco.
How did it get there?
Disease ecologist says scientists don’t know for sure. But they have a top theory: The virus spread through bats.
Many signs point to bats as the main source of Ebola. Scientists have found Ebola antibodies in bat species that are widespread throughout Africa. The virus infects and replicates inside bats, but it doesn’t kill the animals. So bats can easily spread Ebola.
And bats get around. Some can migrate hundreds, even thousands of miles.
Combine that with the item I posted about earlier … and my mind went in a very odd direction as I was doing some routine work in the bindery this afternoon: what if …
… what if a few years ago someone with some limited precognitive ability (either technological or psychic) was able to foresee an Ebola epidemic which made it to the US and then was spread by our native bat population?
And then what if they decided to do something to stop that epidemic before it ever happened … by decimating the bat population?
Yeah, sometimes the ideas I get kinda scare even me.

Sorry for my absence here — I’ve been very busy with a another big project, one which I can’t discuss publicly just yet. But soon.
Without wanting to buy-into the complete panic in some corners about Ebola, here are a couple of very sober articles to consider, which are less about the actual disease and more about what such a pandemic does to the society it hits:
Looters Attack Liberia Ebola Quarantine Center, Patients Under Observation Return Home
Battling the deadly outbreak of Ebola in Liberia has been a mammoth task for the country’s government and international aid agencies. Over the weekend combating the virus’ spread got even harder when a quarantine center in Monrovia was attacked, and 17 patients being monitored for possible infection fled the medical facility. The Liberian government initially said all of the patients had been relocated to another facility after the West Point health center was looted on Saturday, but later admitted that 17 patients had gone “back into their communities,” the BBC reports.
And this one from last week:
You Are Not Nearly Scared Enough About Ebola
Attention, World: You just don’t get it.
You think there are magic bullets in some rich country’s freezers that will instantly stop the relentless spread of the Ebola virus in West Africa? You think airport security guards in Los Angeles can look a traveler in the eyes and see infection, blocking that jet passenger’s entry into La-la-land? You believe novelist Dan Brown’s utterly absurd description of a World Health Organization that has a private C5-A military transport jet and disease SWAT team that can swoop into outbreaks, saving the world from contagion?
Wake up, fools. What’s going on in West Africa now isn’t Brown’s silly Inferno scenario — it’s Steven Soderbergh’s movie Contagion, though without a modicum of its high-tech capacity.
And from that second article, more to my point:
I myself have received emails from physicians in these countries, describing the complete collapse of all non-Ebola care, from unassisted deliveries to untended auto accident injuries. People aren’t just dying of the virus, but from every imaginable medical issue a system of care usually faces.
That’s the thing — a pandemic is bad enough in its own right, when a disease such as Ebola has a mortality of more than 50% under the best conditions. Consider how much worse the impact will be once the overall public health system collapses due to the death of doctors and nurses, when deliveries can’t be made to restock supplies, when whole cities are quarantined, when people begin to really panic.
That is the horror of a true global pandemic. Like the one in St Cybi’s Well.
Cheery thought, eh?

PS: Two other unrelated things I want to mention. The first is thanks to all who participated in Helping Cassandra – you made a real difference. And the second is just to link to a blog post about some black powder shooting I did this past weekend with some very fun historical guns.

nor even a simple ‘microbot‘ from Communion of Dreams, but still, this is pretty cool and could lead to either of those technologies:
Transformer Paper Turns Itself Into A Robot. Cool!
Every so often, a scientific paper just begs for a sexy headline.
Consider this study in the current issue of Science: “A Method for Building Self-Folding Machines.” A bit bland, you’ll no doubt agree. A Real-Life, Origami-Inspired Transformer is how the journal’s public affairs department referred to it. Now that’s more like it.
* * *
It’s now possible to print electronic circuits on a flat sheet of paper. So if you use some clever folding techniques (based on the ancient art of paper folding called origami), you can fold these sheets into useful structures — maybe a crab-shaped robot that could scuttle across the floor, or a swan-shaped robot that could really fly.
Kinda like the beastie up above there. The really clever bit was using a thermal-activated material called a shape memory polymer which would cause the paper (or whatever material) to fold as needed. So you basically create flat-pack robots which can be remotely activated into a useful machine as needed.
It’s fun living in the future.

*Named after John von Neumann, who among many other impressive accomplishments was instrumental in developing the concept of self-replicating machines. The term has been commonly used this way in Science Fiction for decades.

For one reason and another, this past week has been a little rough, hence the paucity of posts. The rejection from the agent kinda took the wind out of my sails a bit, since I thought that the prospects were good. And continued news on the Ebola front* kept reminding me just how grim St Cybi’s Well is getting, in regards to the onset of the fire-flu (though I hope that other aspects of the novel more than balance that out for the reader).
But now the winds have shifted again, and things are looking up. We’ve gotten a bunch of bids in the auction to help my friend (though you can still pick up a hand-bound limited edition hardcopy of Communion of Dreams for a song). There’s a new review of CoD up on Amazon. And this morning I got word that a major new project I’ve been involved with helping to get organized is going to be implemented — more on that when there’s an official announcement in a couple of weeks. But it’s kinda a big deal and one which I am excited to be part of. Oh, and there’s a fun little item here about a recent book conservation job I did which might be of interest.
So, those are the latest developments. Watch for more to come. Oh, and go put a bid in on something on the auction site — there are a number of great items available! Thanks!
Jim Downey
*I do want to note that I don’t think that Ebola poses a significant risk to people in the US. We have the medical infrastructure to deal with isolated cases, which is likely all that we’ll see here. There’s no reason to get into a panic. But that doesn’t change the horror of the disease itself, nor the impact that it is having on people in Guinea, Liberia, Nigeria, and Sierra Leone.

Good news! This morning the bidding opened on the auction I mentioned the other day, and I understand that there’s already something of a bidding war on some of the “become immortal” options I offered:
Be Famous! Have your name (or the name of a loved one, pet, etc) included in my next novel! Can be a character, a named place (manor/restaurant/pub), a book title/author, et cetera. Any sort of name you wish.
You have three choices:
-
Passing mention. Five available.
-
Name and some description. Three available.
-
Tertiary character, who will have some dialog & interaction with other characters. One available.
Yay! Thanks for the vote of confidence, and for helping out my friend!
* * *
I’ve seen several preliminary news items on this, and it’s … intriguing.
Nasa validates ‘impossible’ space drive
Nasa is a major player in space science, so when a team from the agency this week presents evidence that “impossible” microwave thrusters seem to work, something strange is definitely going on. Either the results are completely wrong, or Nasa has confirmed a major breakthrough in space propulsion.
Very intriguing. Basically, this is the third test conducted on a theoretical reactionless drive, with NASA (British publications consider it stylistically appropriate to just capitalize the first letter) doing the independent testing of previous claims. It’ll be interesting to see what comes out of this.
* * *
From three months back:
…but the other is far enough along that I’ll share: there’s a literary agent who is potentially interested in representing me, something which I have been thinking about for a while.
***
I’ll keep you posted as to any concrete developments.
Well, I just got a very nice note back from said agent, who complimented me in several ways but said that he wasn’t going to represent me after all.
Rejection is part of the game, and any writer or artist has to come to terms with that, or you might as well just give up. As I told a friend earlier:
He’s gotta do what he thinks makes business sense – when I ran the gallery, I had to turn down hundreds of artists who wanted us to represent them. And as I told them, just because I wasn’t going to rep them didn’t in any way mean that their work wasn’t quality. So I understand the equation from both sides of the = sign …
Still … I think I might take the rest of the afternoon off.
Do something nice for my friend. Go place a bid on something which interests you.
