That’s from the 1951 classic The Thing from Another World, one of the first (and defining) science fiction movies which set the stage for much of what was to come even to the present day.
It was also very much a product of the early Cold War era, reflecting the fear* of the USSR and atomic weaponry. This is typical — science fiction usually is a reflection of (or commentary on) the technology and social conditions of the era when it was created.
So, what to make of two news items which showed up this week?
Here’s the first:
It is now legal for law enforcement in North Dakota to fly drones armed with everything from Tasers to tear gas thanks to a last-minute push by a pro-police lobbyist.
With all the concern over the militarization of police in the past year, no one noticed that the state became the first in the union to allow police to equip drones with “less than lethal” weapons. House Bill 1328 wasn’t drafted that way, but then a lobbyist representing law enforcement—tight with a booming drone industry—got his hands on it.
And here’s the second:
Hang on to your drone. Boeing’s developed a laser cannon specifically designed to turn unmanned aircraft into flaming wreckage.
The aerospace company’s new weapon system, which it publicly tested this week in a New Mexico industrial park, isn’t quite as cool as what you see in Star Wars—there’s no flying beams of light, no “pew! pew!” sound effects. But it is nonetheless a working laser cannon, and it will take your drone down.

Instead of a massive laser mounted on a dedicated truck, the compact system is small enough to fit in four suitcase-sized boxes and can be set up by a pair of soldiers or technicians in just a few minutes. At the moment, it’s aimed primarily at driving drones away from sensitive areas.
I’m already seeing posts by friends on social media complaining about drones being operated by annoying neighbors, with discussion about what possible solutions there might be to deal with them (both by legal recourse and um, more informal approaches). There have been a number of news items already about people who have shot down drones, and there’s even a company advertising a specific kind of shotgun ammunition for just that.
“Watch the skies!”, indeed.

I don’t write military fiction. Not my thing.
But for St Cybi’s Well, the main character has a relevant military background, as an A-10 (Warthog) pilot. Here’s a bit from Chapter Seven: Dinas Maelor when he and another character are reminiscing about their service in Desert Storm:
The two men sat for a moment, considering one another. After a while, Jones spoke. “I’m not surprised you don’t remember me clearly. You and I just shook hands in passing at that meeting. And while I was pretty worn out by several days of babysitting a royal in the middle of an ongoing battle, you’d just barely gotten out of your A-10 in time to clean up and make the audience. How many sorties did you fly in those three days?”
“A lot.” Darnell took another sip. “And then a lot more a month later.”
“A whole lot. And always in the thick of it. Two of your Hogs were so badly shot up they were scrapped. And that’s saying something, as tough as those things are.”
“Yeah, it’s a hell of an airframe.” Darnell smiled. “So, you checked up on me?”
“When this assignment came in, I recognized your name, so yeah, I went back through your record. Impressive.” Jones returned the smile. “Almost as impressive on paper as what I saw you do to that line of T-55s and BMPs. You crippled just the right vehicles to pin them in place so you could then coolly destroy them. Most other pilots would have tried to take out the line in the first pass, giving too much time for some to scatter. Not you. You nailed the head and tail, then came back for the rest. That was smart, and daring.”
I was reminded of that by this passage in an article on Wired:
Close air support is a vital job that, when properly executed, can mean the difference between life and death for soldiers. It’s highly dangerous, because it requires flying at altitudes low enough to discern friend from foe, leaving the plane particularly vulnerable to ground-based anti-aircraft fire.
But the Warthog was specifically designed for close air support: the cockpit sits in a 1,200 pound titanium tub, specifically designed to withstand fire from anti-aircraft shells at close range. Every system is double or triple redundant, and it can take a ridiculous amount of abuse. It can continue flying if it’s lost an entire engine, part of its tail, or even half a wing.
It’s been a very busy week for me with book conservation work. But I delivered that this afternoon, so can relax and appreciate the next couple of days for what they are. More on that later.

Two brief news items in the last day or so illustrate just *how much* fundamental knowledge we don’t have about our own biology.
The first is this good article from Wired about building a comprehensive model of the human brain: A First Big Step Toward Mapping the Human Brain
The Allen Cell Types Database, on its surface, doesn’t look like much. The first release includes information on just 240 neurons out of hundreds of thousands in the mouse visual cortex, with a focus on the electrophysiology of those individual cells: the electrical pulses that tell a neuron to fire, initiating a pattern of neural activation that results in perception and action. But understanding those single cells well enough to put them into larger categories will be crucial to understanding the brain as a whole—much like the periodic table was necessary to establish basic chemical principles.
Consider that: we’re just now really building a good map of how the different neurons interact within one small component of the brain. And not even the human brain, at that.
And this news story, which came as a shock to me when I heard it on NPR: Seasons May Tweak Genes That Trigger Some Chronic Diseases
From the story:
The seasons appear to influence when certain genes are active, with those associated with inflammation being more active in the winter, according to new research released Tuesday.
* * *
Other researchers say the findings could have far-reaching implications.
“The fact that they find so many genes that go up and down over the seasons is very interesting because we just didn’t know that our bodies go through this type of seasonal change before,” says Akhilesh Reddy, who studies circadian rhythms at the University of Cambridge but was not involved in the new research. “And if you look at the actual genetic evidence for the first time, it’s pretty profound really.”
Again, this is a really basic bit of science — akin to understanding how the sequence of gene expression leads to the development of an organism. Learning that your genetic activity changes during the year means that illnesses are much more dynamic than anyone realized previously.
Not to get too Rumsfeldian, but it really is important to know what we don’t know, as seen between the two items above. In the first case, researchers set out to build a model because they knew that they needed the basic knowledge. In the other, it was investigation of a mystery which led to an unexpected discovery.
And in both cases, it’s science at work. And very cool.

From page two of Communion of Dreams:
He paused there at the railing, right hand manipulating the thin-film controls under the skin on the back of his left hand. Looking out over the herd of slowly moving animals, a see-through display came up before him. Nothing new on the nets. So, whatever the emergency was, it wasn’t public knowledge yet. He turned, opened the door to the station, and stepped inside.
From a new article on Wired this morning:
Gannon is exploring modeling techniques that use the human skin as their primary interface. Her prototype is called Tactum. Instead of creating free-floating models in software like CAD, Gannon’s setup uses a Kinect camera and a projector to create a virtual modeling environment right on your hand.
The projector beams blue lights onto the skin. That light represents the base geometry of the band you’ll eventually wear. The Kinect tracks your body and space and keeps the projection aligned. To adjust the design, you drag it with your fingers; there’s no layer of mediation, you just manipulate the form directly. “You could be pinching, touching, poking, prodding and that visual geometry on your arm without having to go through any computer,” Gannon says. “Your skin and hand are the equivalent of the mouse and keyboard.”
Another step in Communion of Dreams becoming reality.

The reviews have been mixed, but one aspect of the new movie Interstellar is pretty cool: the rendering of the black hole depicted in the movie. Even moreso since it is as scientifically accurate as possible, based on close collaboration with noted astrophysicist Kip Thorne:
Still, no one knew exactly what a black hole would look like until they actually built one. Light, temporarily trapped around the black hole, produced an unexpectedly complex fingerprint pattern near the black hole’s shadow. And the glowing accretion disk appeared above the black hole, below the black hole, and in front of it. “I never expected that,” Thorne says. “Eugénie just did the simulations and said, ‘Hey, this is what I got.’ It was just amazing.”
In the end, Nolan got elegant images that advance the story. Thorne got a movie that teaches a mass audience some real, accurate science. But he also got something he didn’t expect: a scientific discovery. “This is our observational data,” he says of the movie’s visualizations. “That’s the way nature behaves. Period.” Thorne says he can get at least two published articles out of it.
And in a nice bit of serendipity, there’s another fantastic bit of astrophysics in the news just now: actual images of planetary genesis from ALMA. Check it out:
A new image from ALMA, the Atacama Large Millimeter/submillimeter Array, reveals extraordinarily fine detail that has never been seen before in the planet-forming disc around a young star. ALMA’s new high-resolution capabilities were achieved by spacing the antennas up to 15 kilometers apart . This new result represents an enormous step forward in the understanding of how protoplanetary discs develop and how planets form.
ALMA has obtained its most detailed image yet showing the structure of the disc around HL Tau , a million-year-old Sun-like star located approximately 450 light-years from Earth in the constellation of Taurus. The image exceeds all expectations and reveals a series of concentric and bright rings, separated by gaps.
That’s not computer-rendered theory. That’s an actual image, showing the formation of planets around this very young star.

I know sometimes people think that I am anti-government or anti-authority because I rant about infringements of our civil rights and personal liberties. I’ll cop to some of that, since I do believe that trading freedom (or even privacy) for a false security is foolish.
But more importantly, I think that the whole notion of secret courts or secret laws or secret lists are dangerous because they can be abused not due to an over-enthusiastic effort to protect the country, but because of personal grudges or to cover up incompetence. Without the ability to challenge these secret acts/actions, those abuses and incompetence cannot be brought to light and corrected. This is the perfect example of that:
The government contested a former Stanford University student’s assertion that she was wrongly placed on a no-fly list for seven years in court despite knowing an FBI official put her on the list by mistake because he checked the “wrong boxes” on a form, a federal judge wrote today.
The agent, Michael Kelly, based in San Jose, misunderstood the directions on the form and “erroneously nominated” Rahinah Ibrahim to the list in 2004, the judge wrote.
“He checked the wrong boxes, filling out the form exactly the opposite way from the instructions on the form,” U.S. District Judge William Alsup wrote (.pdf) today.
* * *
Much of the federal court trial, in which the woman sought only to clear her name, was conducted in secret after U.S. officials repeatedly invoked the state secrets privilege and sought to have the case dismissed.
Doctor Ibrahim is the first person to successfully challenge in court being put on a government watch list in the US. It’s highly doubtful that she is the only one to be placed on such a list incorrectly.
National security may benefit from secret lists and hidden actions. But so does bureaucratic incompetence and hidden agendas.
