So, could researchers find clear evidence that an ancient species built a relatively short-lived industrial civilization long before our own? Perhaps, for example, some early mammal rose briefly to civilization building during the Paleocene epoch about 60 million years ago. There are fossils, of course. But the fraction of life that gets fossilized is always minuscule and varies a lot depending on time and habitat. It would be easy, therefore, to miss an industrial civilization that only lasted 100,000 years—which would be 500 times longer than our industrial civilization has made it so far.

We hoped for a bicycle for the mind; we got a Lazy Boy recliner for the mind.
Nicky Case on how Douglas Engelbart’s vision for human-computer augmentation has taken a turn from creation to consumption.
When you create a Human+AI team, the hard part isn’t the “AI”. It isn’t even the “Human”.
It’s the “+”.

Recipes inspired by The Left Hand Of Darkness.
I mostly stuck to Le Guin’s world-building rules for Winter, which were “no large meat-animals … and no mammalian products, milk, butter or cheese; the only high-protein, high-carbohydrate foods are the various kinds of eggs, fish, nuts and Hainish grains.” I did, however, add some hot-climate items found in Manhattan’s Chinatown for their space-age looks and good flavors (dragonfruit, pomelo, galangal, chilis, and kaffir limes).
Serve with hot beer.

Steven Johnson dives deep into the METI project, starting with the Arecibo message and covering Lincos, the Drake equation, and the Fermi paradox.
He also wrote about what he left out of the article and mentions that he’s writing a book on long-term decision making.
In a sense, the METI debate runs parallel to other existential decisions that we will be confronting in the coming decades, as our technological and scientific powers increase. Should we create superintelligent machines that exceed our own intellectual capabilities by such a wide margin that we cease to understand how their intelligence works? Should we ‘‘cure’’ death, as many technologists are proposing? Like METI, these are potentially among the most momentous decisions human beings will ever make, and yet the number of people actively participating in those decisions — or even aware such decisions are being made — is minuscule.

A website dedicated to one of the most, um, interesting solutions to the Yucca Mountain nuclear waste storage problem:
- Engineer cats that change colour in response to radiation.
- Create the culture/legend/history that if your cat changes colour, you should move some place else.
There are T-shirts!

We examine the possibility that Fast Radio Bursts (FRBs) originate from the activity of extragalactic civilizations. Our analysis shows that beams used for powering large light sails could yield parameters that are consistent with FRBs.
I’m guessing Paul Gilster may have thoughts on this.

Churchill, as it turns out, had some pretty solid ideas on SETI.
Churchill was a science enthusiast and advocate, but he also contemplated important scientific questions in the context of human values. Particularly given today’s political landscape, elected leaders should heed Churchill’s example: appoint permanent science advisers and make good use of them.

Philip Ball certainly has a way with words.

Compare and contrast Alien, Starship Troopers, and The Thing with 2001 and Roadside Picnic (and I would throw Solaris into the mix).
Plugging in a monster moves a plot right along, of course, but if that’s all it’s doing, the plot is neglecting to examine how a real biosphere would work. That would be a sensationally complex task, but given the amount of research now going on in astrobiology and exoplanetary science, the suspicion here is that experts could be summoned who could produce such a film. Even so, there is something to be said for not seeing aliens.

It’s still many years away from being a viable storage option, but here’s the latest on using DNA to back up our collective data.
Magnetic tape may survive a few decades, and DVDs even longer, but they are by no means immortal. Data stored in DNA, provided it’s kept cold and dry, could last for thousands of years.

Beautiful visualisations of science and nature.
Made with love by a designer with a molecular biology degree.

I’ve linked to this before, but with the death of Iain M Banks it’s worth re-reading this fascinating insight into The Culture, one of science fictions’s few realistic utopias.
The brief mention here of The Culture’s attitude to death is apt:
Philosophy, again; death is regarded as part of life, and nothing, including the universe, lasts forever. It is seen as bad manners to try and pretend that death is somehow not natural; instead death is seen as giving shape to life.

I, for one, welcome our slime mould overlords.
The slime mould is being used to explore biological-inspired design, emergence theory, unconventional computing and robot controllers, much of which borders on the world of science fiction.

Brilliant little magnetic cuddly nucleobases from Jun. You get all four bases to combine to your heart’s content: cytosine, guanine, adenine, thymine — take that, Pokémon.
