- We Have No Reason to Believe 5G Is Safe (Scientific American) — "The latest cellular technology, 5G, will employ millimeter waves for the first time in addition to microwaves that have been in use for older cellular technologies, 2G through 4G. Given limited reach, 5G will require cell antennas every 100 to 200 meters, exposing many people to millimeter wave radiation... [which are] absorbed within a few millimeters of human skin and in the surface layers of the cornea. Short-term exposure can have adverse physiological effects in the peripheral nervous system, the immune system and the cardiovascular system."
- Situated degree pathways (The Ed Techie) — "[T]he Trukese navigator “begins with an objective rather than a plan. He sets off toward the objective and responds to conditions as they arise in an ad hoc fashion. He utilizes information provided by the wind, the waves, the tide and current, the fauna, the stars, the clouds, the sound of the water on the side of the boat, and he steers accordingly.” This is in contrast to the European navigator who plots a course “and he carries out his voyage by relating his every move to that plan. His effort throughout his voyage is directed to remaining ‘on course’."
- on rms / necessary but not sufficient (p1k3) — "To the extent that free software was about wanting the freedom to hack and freely exchange the fruits of your hacking, this hasn’t gone so badly. It could be better, but I remember the 1990s pretty well and I can tell you that much of the stuff trivially at my disposal now would have blown my tiny mind back then. Sometimes I kind of snap to awareness in the middle of installing some package or including some library in a software project and this rush of gratitude comes over me."
- Screen time is good for you—maybe (MIT Technology Review) — "Przybylski admitted there are some drawbacks to his team’s study: demographic effects, like socioeconomics, are tied to psychological well-being, and he said his team is working to differentiate those effects—along with the self-selection bias introduced when kids and their caregivers report their own screen use. He also said he was working to figure out whether a certain type of screen use was more beneficial than others."
- This Map Lets You Plug in Your Address to See How It’s Changed Over the Past 750 Million Years (Smithsonian Magazine) — "Users can input a specific address or more generalized region, such as a state or country, and then choose a date ranging from zero to 750 million years ago. Currently, the map offers 26 timeline options, traveling back from the present to the Cryogenian Period at intervals of 15 to 150 million years."
- Understanding extinction — humanity has destroyed half the life on Earth (CBC) — "One of the most significant ways we've reduced the biomass on the planet is by altering the kind of life our planet supports. One huge decrease and shift was due to the deforestation that's occurred with our increasing reliance on agriculture. Forests represent more living material than fields of wheat or soybeans."
- Honks vs. Quacks: A Long Chat With the Developers of 'Untitled Goose Game' (Vice) — "[L]ike all creative work, this game was made through a series of political decisions. Even if this doesn’t explicitly manifest in the text of the game, there are a bunch of ambient traces of our politics evident throughout it: this is why there are no cops in the game, and why there’s no crown on the postbox."
- What is the Zeroth World, and how can we use it? (Bryan Alexander) — "[T]he idea of a zeroth world is also a critique. The first world idea is inherently self-congratulatory. In response, zeroth sets the first in some shade, causing us to see its flaws and limitations. Like postmodern to modern, or Internet2 to the rest of the internet, it’s a way of helping us move past the status quo."
- It’s not the claim, it’s the frame (Hapgood) — "[A] news-reading strategy where one has to check every fact of a source because the source itself cannot be trusted is neither efficient nor effective. Disinformation is not usually distributed as an entire page of lies.... Even where people fabricate issues, they usually place the lies in a bed of truth."
'Restorying' your life as a hero's journey
There are some people, perhaps most people, who do not expect setbacks and problems in life. They seem to think that it should all be smooth sailing, and that anything that interferes with this unarticulated plan is somehow annoying or unfair.
Perhaps because I spent my teenage years reading philosophy (which I studied at university) and then my adult life reading Stoic philosophers such as Epictetus and Marcus Aurelius, this isn’t my view. Instead, I’m well aware that everyone has to deal with setbacks and, in fact, they make you stronger and more focused.
This article discusses the results of research based on interventions taking as its basis The Hero’s Journey by Joseph Campbell. He noticed that cultures around the world had foundational stories which were based on a similar structure. The researchers took this approach, updated it for modern life, and used the structure as an intervention to help individuals to tell better stories about their lives.
What do Beowulf, Batman and Barbie all have in common? Ancient legends, comic book sagas and blockbuster movies alike share a storytelling blueprint called “the hero’s journey.” This timeless narrative structure, first described by mythologist Joseph Campbell in 1949, describes ancient epics, such as the Odyssey and the Epic of Gilgamesh, and modern favorites, including the Harry Potter, Star Wars and Lord of the Rings series. Many hero’s journey stories have become cultural touchstones that influence how people think about their world and themselves.Source: To Lead a Meaningful Life, Become Your Own Hero | Scientific AmericanOur research reveals that the hero’s journey is not just for legends and superheroes. In a recent study published in the Journal of Personality and Social Psychology, we show that people who frame their own life as a hero’s journey find more meaning in it. This insight led us to develop a “restorying” intervention to enrich individuals’ sense of meaning and well-being. When people start to see their own lives as heroic quests, we discovered, they also report less depression and can cope better with life’s challenges.
[…]
To explore the connection between people’s life stories and the hero’s journey, we first had to simplify the storytelling arc from Campbell’s original formulation, which featured 17 steps. Some of the steps in the original set were very specific, such as undertaking a “magic flight” after completing a quest. Think of Dorothy, in the novel The Wonderful Wizard of Oz, being carried by flying monkeys to the Emerald City after vanquishing the Wicked Witch of the West. Others are out of touch with contemporary culture, such as encountering “women as temptresses.” We abridged and condensed the 17 steps into seven elements that can be found both in legends and everyday life: a lead protagonist, a shift of circumstances, a quest, a challenge, allies, a personal transformation and a resulting legacy.
For example, in The Lord of the Rings, Frodo (the protagonist) leaves the Shire (a shift) to destroy the Ring (a quest). Sam and Gandalf (his allies) help him face Sauron’s forces (a challenge). He discovers unexpected inner strength (a transformation) and then returns home to help the friends he left behind (a legacy). In a parallel way in everyday life, a young woman (the protagonist) might move to Los Angeles (a shift), develop an idea for a new business (a quest), get support from her family and new friends (her allies), overcome self-doubt after initial failure (a challenge), grow into a confident and successful leader (a transformation) and then help her community (a legacy).
[…]
Anyone can frame their life as a hero’s journey—and we suspect that people can also benefit from taking small steps toward a more heroic life. You can see yourself as a heroic protagonist, for example, by identifying your values and keeping them top of mind in daily life. You can lean into friendships and new experiences. You can set goals much like those of classic quests to stay motivated—and challenge yourself to improve your skills. You can also take stock of lessons learned and ways that you might leave a positive legacy for your community or loved ones.
Laying to rest a foundational myth
The widely accepted “Man the Hunter” theory proposes that during human evolution, men evolved to hunt while women focused on gathering and domestic duties such as child-rearing. However, as reported in Scientific American, it turns out that recent research is challenging this view.
Scientific studies indicate that women are physiologically better suited for endurance tasks, which is crucial for hunting. Also, although ignored for societal reasons (read: the patriarchy) archaeological records and ethnographic studies demonstrate that women have a longstanding history of participating in hunting activities.
I’m pleased that our 12 year-old daughter inhabits a world where female footballers are allowed to compete in the same way as men in most areas of life. There is still a lot of inequality, but it helps when we dismantle these foundational myths.
Mounting evidence from exercise science indicates that women are physiologically better suited than men to endurance efforts such as running marathons. This advantage bears on questions about hunting because a prominent hypothesis contends that early humans are thought to have pursued prey on foot over long distances until the animals were exhausted. Furthermore, the fossil and archaeological records, as well as ethnographic studies of modern-day hunter-gatherers, indicate that women have a long history of hunting game. We still have much to learn about female athletic performance and the lives of prehistoric women. Nevertheless, the data we do have signal that it is time to bury Man the Hunter for good.Source: The Theory That Men Evolved to Hunt and Women Evolved to Gather Is Wrong | Scientific American[…]
So much about female exercise physiology and the lives of prehistoric women remains to be discovered. But the idea that in the past men were hunters and women were not is absolutely unsupported by the limited evidence we have. Female physiology is optimized for exactly the kinds of endurance activities involved in procuring game animals for food. And ancient women and men appear to have engaged in the same foraging activities rather than upholding a sex-based division of labor. It was the arrival some 10,000 years ago of agriculture, with its intensive investment in land, population growth and resultant clumped resources, that led to rigid gendered roles and economic inequality.
Now when you think of “cave people,” we hope, you will imagine a mixed-sex group of hunters encircling an errant reindeer or knapping stone tools together rather than a heavy-browed man with a club over one shoulder and a trailing bride. Hunting may have been remade as a masculine activity in recent times, but for most of human history, it belonged to everyone.

How 'flu kills people
Nasty:
After entering someone's body—usually via the eyes, nose or mouth—the influenza virus begins hijacking human cells in the nose and throat to make copies of itself. The overwhelming viral hoard triggers a strong response from the immune system, which sends battalions of white blood cells, antibodies and inflammatory molecules to eliminate the threat. T cells attack and destroy tissue harboring the virus, particularly in the respiratory tract and lungs where the virus tends to take hold. In most healthy adults this process works, and they recover within days or weeks. But sometimes the immune system's reaction is too strong, destroying so much tissue in the lungs that they can no longer deliver enough oxygen to the blood, resulting in hypoxia and death.
