Sweden-2.

“Welcome to rural Sweden, sometime in the late ’80s. Citizens go about their mundane lives and children explore the countryside. But something isn’t quite right. Robots and hovercrafts are commonplace, and decaying science facilities sprout from the harsh Scandinavian landscape. There’s even a rumor circulating that dinosaurs have returned from the dead after some failed experiment.”

This has been languishing in the bookmarks for awhile: Artist Simon Stålenhag depicts a Scandinavian future that never was. “As he explains to The Verge, “The only difference in the world of my art and our world is that…ever since the early 20th century, attitudes and budgets were much more in favor of science and technology.'” [More available at Stålenhag’s website.]

All We Have is Now.

“Humans are good at a lot of things, but putting time in perspective is not one of them…If the Earth formed at midnight and the present moment is the next midnight, 24 hours later, modern humans have been around since 11:59:59pm—1 second. And if human history itself spans 24 hours from one midnight to the next, 14 minutes represents the time since Christ.”

Time? What time do you think we have? As has been going around the Interweb, a series of intriguing timelines ranging from last year to the age of the universe. Among the interesting facts pointed out: “The T-Rex is closer in time to seeing a Justin Bieber concert than seeing a live stegosaurus.” Also: “When we refer to the most ancient of ancient history, we are still just talking about…less than 3% of the time that humans who look like us have existed.”

Chasing Darkness.

“How dark it would have been—imagine leaning out your door and, on the darkest nights, not being able to see more than a few feet in any direction. Historian Peter Baldwin describes as ‘downright perilous’ the streets in early American cities, with few paved and then those only with cobblestones…What lights did exist were intended only as beacons or guides rather than to illuminate the night. The New York street lanterns burning whale oil were, in 1761, merely ‘yellow specks engulfed by darkness,’ and, even more than 100 years later, its gas lamps were still ‘faint as a row of invalid glow-worms.'”

In Slate, Paul Bogart describes (and laments) the end of night all across the world. “With at least 30 percent of all vertebrates and more than 60 percent of all invertebrates worldwide nocturnal, and with many of the rest crepuscular, [the] implications are enormous.”

We…learn. We…feed.

“‘Slime mould’s remarkable problem-solving capabilities are well-documented and include finding the shortest path between different food sources. It also displays memory, in a similar way to a novel electrical component called a memristor, which has in turn been likened to the functionality of biological brains. ‘It’s one of the simplest organisms that can learn,’ says Gale.”

And now, IT HAS A FACE. Scientists program an old-timey robot to dramatize the electrical signals emanating from slime mold. In a 100,000 years, this is going to seem like one of those Skynet-level bad ideas. And the hat is particularly creepy touch — Very Something Wicked This Way Comes.

Explorers on the Moon.

“The next time you walk outside on a clear night and see the moon smiling down at you, think of Neil Armstrong and give him a wink.” A belated happy 44th anniversary to the Apollo 11 crew, the first without Neil Armstrong. Speaking of which, it’s now been over 40 years since man walked on the moon — ’bout time to go back, dontchathink? (Spiffy Tintin image via LinkMachineGo.)

Sleep: Nature’s Reset Button.

“More than 20 years ago…we began to suspect that the brain’s activity during slumber may somehow restore to a baseline state the billions of neural connections that get modified every day by the events of waking life. Sleep, in this telling, would preserve the ability of the brain’s circuitry to form new memories continually over the course of an individual’s lifetime without becoming oversaturated or obliterating older memories.”

More Science of Sleep: In Scientific American, two Italian academics put forward their “synaptic homeostasis hypothesis” (SHY) of slumber, whereby the brain weakens (not strengthens, as is usually assumed) synaptic links overnight. “In principle, SHY explains the essential, universal purpose of sleep…sleep restores the brain to a state where it can learn and adapt when we are awake…Most generally, sleep is the price we pay for the brain’s plasticity — its ability to modify its wiring in response to experience.”

Also part of SHY: the idea of “local sleep”: “Recently we have even found that prolonged or intense use of certain circuits can make local groups of neurons ‘fall asleep’ even though the rest of the brain (and the organism itself) remains awake…It seems that when we have been awake for too long or have overexerted certain circuits, small chunks of the brain may take quick naps without giving notice.” I believe in Internet parlance this is known as “haz-ing the dumb.”

Uatu Degrasse Sagan.

(Klaatu barada nitko?) All that being said, one Comic-Con remake reveal I can get excited about — although “Executive Producer Seth McFarlane” gives me a moment of pause — is Neil DeGrasse Tyson’s upcoming 13-episode reboot of Cosmos.

“‘There’s never been a more important time for COSMOS to re-emerge than right now. I want to make this so entertaining, and so flashy, and so exciting that people who have no interest in science will watch just because it’s a spectacle,'” MacFarlane said in a news release.”

Good News, Coffee Achievers.

“In one large-scale epidemiological study from last year, researchers primarily at the National Cancer Institute parsed health information from more than 400,000 volunteers, ages 50 to 71, who were free of major diseases at the study’s start in 1995…men who reported drinking two or three cups of coffee a day were 10 percent less likely to have died than those who didn’t drink coffee, while women drinking the same amount had 13 percent less risk of dying during the study.”

Better living through chemistry: The NYT’s Gretchen Reynolds touts the potential medical benefits of caffeine addiction. “Participants with little or no caffeine circulating in their bloodstreams were far more likely to have progressed to full-blown Alzheimer’s than those whose blood indicated they’d had about three cups’ worth of caffeine.” Factor in all the taurine I consume to boot, and I’m disco.

Seven Minutes of Fury.

“In 12 exercises deploying only body weight, a chair and a wall, it fulfills the latest mandates for high-intensity effort…into about seven minutes of steady discomfort — all of it based on science.”

To complement Calvinism: The NYT lays out a seven-minute workout that might actually work. “The exercises should be performed in rapid succession, allowing 30 seconds for each, while, throughout, the intensity hovers at about an 8 on a discomfort scale of 1 to 10…Those seven minutes should be, in a word, unpleasant.”

Good Tom Zhang.

“The stereotype, outmoded though it is, is that new mathematical discoveries emerge from the minds of dewy young geniuses. But Zhang is over 50. What’s more, he hasn’t published a paper since 2001.”

In a surprising mathematical coup, UNH lecturer Yitang “Tom” Zhang has apparently cracked open a centuries-standing “twin-prime” puzzle about the “bounded gaps” in the distribution of prime numbers. “Yitang Zhang couldn’t get a teaching job after receiving his Ph.D., and things got so dismal at one point that he even became a Subway sandwich artist in order to stay afloat.”
