FEAR ITSELF:

Curing cancerphobia: How the psychology of fear distorts our view of cancer (David Ropeik, 11/29/23, Big Think)

Fighting the entrenched misbelief that “everything causes cancer” is hard. The highly respected Cancer Research UK tried, calling the study factually incorrect and misleading, as well as directly addressing the psychological factors of control and less fear of what is natural than what is human-made, saying, “It can be tempting to worry about our cancer risk from external things like pollution and chemicals more than from things we can control, like our lifestyles. But decades of research have shown that lifestyle factors — such as not smoking, keeping a healthy weight, limiting alcohol, getting enough exercise, and avoiding sunburn — have an important effect on cancer risk. In contrast, the evidence that pollution and industrialization has a widespread role in UK cancer rates is weak.”

The belief that cancer is mostly caused by human-made substances explains why any mention of the word “chemicals” or “radiation” sets off alarms. (Magnetic resonance imaging was originally called nuclear magnetic resonance imaging. The “nuclear” was dropped to avoid the frightening allusion to weapons and radiation.) And it explains why scientists frustrated by “chemophobia” and “radiophobia,” corollaries of cancerphobia, try to reduce those fears by arguing, “All of nature is made out of chemicals,” and, “If we’re worried about nuclear power we should also worry about natural sources of radiation like the sun and bananas.”

Klarna freezes hiring, citing AI ‘productivity gains’ (Siôn Geschwindt, December 4, 2023, Next Web)


In a hiring freeze that CEO Sebastian Siemiatkowski attributes to the rise of AI, Swedish fintech unicorn Klarna is no longer recruiting staff beyond its engineering department. […]

The chief exec of the buy now, pay later app said that the productivity gains from using tools like ChatGPT meant the company now needs “fewer people to do the same thing.”

GUTENBERG’S WAS CHILD’S PLAY:

RESEARCHERS INVENTED WILD TECHNOLOGY TO 3D-PRINT STEEL: ‘INNOVATION THIS DECADE WILL BE CRUCIAL’ (Jeremiah Budin, December 5, 2023, Renew Economy)

Steel production is responsible for 3 billion metric tons (about 3.3 billion tons) of carbon dioxide — or around 8% of all planet-warming pollution per year — according to the World Steel Association, as cited by Chemical & Engineering News. But researchers may have just developed a new way to bring that number down by 3D printing the metal.

A team at the University of Cambridge developed the method, which uses the traditional 3D printing laser as a “microscopic hammer” to harden the metal during processing, instead of the traditional “heat and beat” method in which the metal is hardened with a hammer and softened with fire.

NO MAN IS A FAILURE WHO HAS FRIENDS:

Friendship as Soulcraft: How I made friends in my thirties. (Matt Dinan, Fall 2023, Hedgehog Review)

As Aristotle points out, even if one had every other good, one would still choose to have friends. This recognition is what led me to make friends in my thirties: I came to see that because you don’t need friends, and they don’t need you, you must seek them out. And an insufficient understanding of how this makes friendship different from other forms of love is one of the primary roadblocks to finding friendship in our time and place.

There is security in the messy neediness of love, the occult magnetic fields that attract and repel. Passion means to suffer, to be set upon. This is not to speak ill of love, but only to observe that since friendship is more freely chosen, it rests on unstable ground. Romantic love holds us together through mutual awareness of our neediness, but friendship does not arise from any need. Filial love is so powerful because it is, ideally without caveat, the sort of belonging one can neither earn nor lose. Some of the deepest hurts in human life consequently arise when we do lose that love, when the familiar becomes estranged. Family members, even those in a family you have some choice in forming, are the same type—“kin.” But the friend is some “other,” a stranger I have come to prefer.

HE WAS NOT ON TO NOTHING:

Understanding Sigmund Freud’s Id, Ego and Superego (Emilie Le Beau Lucchesi, Nov 9, 2023, Discover)

Exploring the Id
The first part, the id, was both innate and unconscious. Freud saw it as the driving force behind a person’s impulse to satiate their desires. The id wasn’t conceptualized as something that regulated or judged a person’s needs or wants. Rather, the id was the animalistic compulsion to seek pleasure and satisfy impulses.

The Development of the Ego
The ego began to develop within the first few years of a child’s life, Freud argued. The ego was the person’s sense of self, and it had to negotiate between the id’s impulses and the superego’s cautious urgings to not act in ways that would be socially unacceptable.

Understanding the Superego
Around the age of six, Freud theorized that a person’s superego began to form. Freud saw the superego as a guardian that pressured the ego to resist the id’s impulses in order to fit social norms.

Perhaps best thought of this way: The id is pure desire; the ego is the personal limitation on acting out those desires; and, the supego is the societal limitations. The rest is bunk.

IT’S IMPOSSIBLE TO OVERSTATE DEFLATIONARY PRESSURES:

The Medical-Robotics Revolution (Jonathan Shaw, Apr. 6th, 2022, Harvard Magazine)


What if a cardiac surgeon could operate on a beating heart without opening the patient’s chest? Or a flexible robot could navigate the delicate branching of blood vessels, or bronchi in the lungs, and then stiffen to perform surgery at its tip? Or a magnetic field could be engineered to drive a plaque-clearing robot inside a person’s arteries?

These kinds of innovations are already in the vanguard of the field of medical robotics, says professor of surgery Pierre Dupont, a leading designer of robotic systems for use in healthcare. “I thought of going into medicine instead of engineering,” he admits, “so when I had the chance to combine the two, it was a fantastic opportunity.” The field encompasses precision instruments that can be deployed by doctors inside the human body for visualization, diagnosis, and treatment, but also patient-focused inventions, from handheld devices that let diabetics control their blood sugar to wearable robots that help stroke patients walk again.

Not all these achievements will make it from the lab. But gradual trends are emerging: toward increasing autonomy for the robots themselves, and greater personalization for users, whether as patients or providers of healthcare.

Above average is over.

THE SLOPE ALWAYS SLIPS:

“Terminalism” — discrimination against the dying — is the unseen prejudice of our times: In hospice care and hospitals, we prioritize those with more life to live over those who are terminally ill. What is that, if not prejudice? (Jonny Thomson, 11/11/23, Big Think)

Reed believes that a lot of people will find it somewhat ridiculous to call these instances a kind of discrimination. When presented with limited resources, surely it’s better to focus on those who have longer to live? In other words, isn’t it okay to value longevity over the moribund?

Reed calls this a structural “terminalist prejudice,” with little philosophical justification for it. He argues that “many of us tend to think, explicitly or implicitly, that a worthwhile life involves both the kind of life that has a future and also enables a person to ‘contribute meaningfully’ to society.”

We don’t want to see ourselves as cruel or prejudiced. We don’t want to accept that we are privately and socially devaluing human life based on our terminalist biases. Dying people are human beings as well. They have brothers and sisters; sons and daughters; or wives and husbands. They read books, watch TV, talk, laugh, and reminisce. If all humans have rights, the dying have rights, too. They are valuable in themselves, not for some abstract, unknown “contribution” they might make. As Reed puts it, “The reason that terminalism matters is that dying persons matter.”

“Life unworthy of life” as the Nazis called it.

WHAT ABOUT…DAYS WHEN THE CORE IS COOL?:

Google switches on first-of-its-kind advanced geothermal project (Loz Blain, November 28, 2023, New Atlas)

[T]he idea is to do for geothermal what fracking did for oil and gas, opening up resources that would otherwise be inaccessible. The company does this by drilling horizontally into deep rock, then injecting pressurized fluid to fracture the rock, creating the kind of fractured, permeable rock you need to harvest geothermal heat energy.


It’s a technique Fervo says can also help get a lot more out of an existing resource, and it radically reduces one of the biggest risks in geothermal energy: the risk of drilling way down into subterranean resources and finding they’re not usable.

The Nevada plant makes a constant 3.4 megawatts of energy, bringing water up from 3,250-ft-long (990-m) horizontal bores some 8,000 ft (2,440 m) below the surface, at temperatures up to 191 °C (376 °F).

CAIN WINS:

Mother plucker: Steel fingers guided by AI pluck weeds rapidly and autonomously (BENJ EDWARDS, 11/28/2023, Ars Technica)

[A] Swedish company named Ekobot AB has introduced a wheeled robot that can autonomously recognize and pluck weeds from the ground rapidly using metal fingers.


The four-wheeled Ekobot WEAI robot is battery-powered and can operate 10–12 hours a day on one charge. It weighs 600 kg (about 1322 pounds) and has a top speed of 5 km/h (2.5 mph). It’s tuned for weeding fields full of onions, beetroots, carrots, or similar vegetables, and it can cover about 10 hectares (about 24.7 acres) in a day. It navigates using GPS RTK and contains safety sensors and vision systems to prevent it from unintentionally bumping into objects or people.

To pinpoint plants it needs to pluck, the Ekobot uses an AI-powered machine vision system trained to identify weeds as it rolls above the farm field. Once the weeds are within its sights, the robot uses a series of metal fingers to quickly dig up and push weeds out of the dirt. Ekobot claims that in trials, its weed-plucking robot allowed farmers to grow onions with 70 percent fewer pesticides. The weed recognition system is key because it keeps the robot from accidentally digging up crops by mistake.
