Krista Varady has been studying intermittent fasting for two decades at the University of Illinois Chicago, and in a 2024 commentary, she and her co-authors set out to systematically debunk four common safety myths about the practice. Read more ›

Psychology says people who find themselves growing lonelier in their 60s and 70s aren’t necessarily becoming antisocial or difficult — they’re often the ones who spent decades being available for everyone else and simply never built a life that came back to them

We’ve got a lazy story we tell about lonely old people. They got prickly. They pushed everyone away. They turned “difficult.” It’s a comforting story, because it lets the rest of us off the hook. Well, they chose this, didn’t they? Mostly they didn’t. The people I’ve watched get lonely in their sixties and seventies ... Read more Read more ›

The less someone knows about a subject, the more likely they are to overestimate their grasp of it — real expertise tends to bring more self-doubt, not less

Confidence is easiest before the hard part has introduced itself. A person who has just learned the vocabulary of a subject can feel strangely fluent. They know enough to speak, not yet enough to hear what is missing. That is why early certainty can be so seductive in work, leadership, investing, hiring, strategy and technology. ...

The quiet reason so many adults stop celebrating their own birthdays isn’t sadness about aging, it’s that somewhere along the way the day stopped feeling like a marker and started feeling like an audit

For many adults, birthdays quietly transform from celebrations into private performance reviews. The dread isn't really about aging — it's about the yearly obligation to justify yourself against a checklist you never agreed to. Read more ›

The Greenland shark drifts through Arctic water at the pace of a slow walk and doesn’t reach sexual maturity until roughly 150 years old, meaning individuals cruising the North Atlantic today were already swimming when the American Revolution began

Greenland sharks swim at a foot per second, grow a centimeter a year, and don't reach sexual maturity until roughly 150 years old — meaning adults reproducing today were born before the American Revolution. Read more ›

Nobody talks about what happens when the agency writing federal cybersecurity standards has no director, no playbook, and a third fewer staff — CISA’s May 2026 leak just made it visible

The US Cybersecurity and Infrastructure Security Agency (CISA) has admitted it began writing its incident response playbook during the incident it was responding to — a breach in which a contractor exposed administrative credentials to Amazon AWS GovCloud accounts and internal CISA systems on a public GitHub repository.

A small blunder can feel strangely enormous from the inside. The awkward pause after a sentence lands badly, the stain noticed too late, the shirt that suddenly seems wrong for the room, the typo in a message to a senior colleague: each one can feel as if it has been placed under a spotlight.

A 2024 New England Journal of Medicine study found microplastics and nanoplastics lodged in the carotid artery plaque of 58% of patients — and those patients were 4.5 times more likely to suffer a heart attack, stroke, or death within three years

A landmark New England Journal of Medicine study found microplastics lodged in the carotid plaque of 58% of patients, and those patients suffered heart attacks, strokes, and death at 4.5 times the rate of their plastic-free peers. Follow-up work in New Mexico and elsewhere is now testing whether cardiology has a new modifiable risk factor on its hands. Read more ›

Singapore had almost no natural resources when it became independent in 1965 — so it invested in education, imported capital and exported increasingly sophisticated products and expertise until it became one of the richest nations on Earth

Singapore’s rise is often told as a neat parable: a small island with almost no natural resources became rich by being disciplined, open and clever. The short version is true enough to be memorable, but too clean to explain much. What made Singapore unusual was not simply that it lacked oil, minerals or agricultural hinterland. ...

We tend to think detachment means becoming cold or disengaged, but occupational psychology uses the word differently: research finds that mentally switching off from work during your free time is associated with less exhaustion, fewer sleep problems and greater life satisfaction

Silicon Canals Editorial Team @ Silicon Canals · 07/12/2026 16:30 EDT

Detachment has a chilly reputation. In ordinary conversation, it can sound like emotional distance, cynicism or a slow retreat from the people and tasks that once mattered. At work, the word can sound even worse, as if an employee has stopped caring, stopped trying or quietly checked out. Occupational psychology uses the word in a ... Read more Read more ›

Psychology suggests people who answer a casual text within seconds but take days to reply to an emotional one aren’t necessarily inconsistent or uncaring — low-stakes messages run on habit, while vulnerable ones demand empathy, reflection and the risk of saying the wrong thing

It is easy to read response time as character. Someone replies instantly to a meme, a logistics question, a restaurant link or a work aside. Then an emotional message arrives, and the same person goes quiet for two days. From the outside, that silence can look like indifference. From the inside, it may be something ...

Psychology says the gap between getting what you wanted and still wanting more is not necessarily a character flaw — it is hedonic adaptation, the brain’s tendency to turn yesterday’s achievement into today’s normal and quietly move the finish line again

There is a particular embarrassment that can arrive after success. A person gets the job, the promotion, the funding, the house, the public proof, the number they used to think would settle something. For a while it does. Then the mind absorbs it into ordinary life, and the next target begins to look less like ... Read more Read more ›

In 1707, a British fleet returning from Gibraltar smashed into the rocks of the Scilly Isles and lost nearly 2,000 sailors in a single night, because the navigators had no reliable way to measure longitude at sea — and the disaster is what pushed Parliament to offer the £20,000 prize that a Yorkshire carpenter named John Harrison would spend 46 years chasing with a clock

The 1707 Scilly naval disaster killed nearly 2,000 sailors and pushed Britain to offer a £20,000 prize for a solution to the longitude problem — a prize that a self-taught Yorkshire clockmaker named John Harrison would spend the rest of his life pursuing. Read more ›

We’re taught that failure is the price of ambition, but psychologists studying explanatory style found that what happens after a setback depends partly on the story a person tells themselves about it: those who see failure as permanent and personal are more likely to become helpless, while those who treat it as temporary and specific are more likely to keep going.

Silicon Canals Editorial Team @ Silicon Canals · 07/12/2026 09:12 EDT

Ambition has a standard story about failure. You take the hit, learn the lesson, and keep moving. It is clean, motivational, and not quite true. Some setbacks become information. Others become identity. The difference is not only the size of the loss. It is also the explanation a person builds around it. Psychologists studying explanatory ... Read more Read more ›

Adults who spent years being the funny one, the capable one, or the strong one in a group often arrive at a moment when the role has kept them so thoroughly in character that they are no longer sure there is anyone left underneath it

There are roles a person chooses, and roles that quietly choose them back. At first, being the funny one, the capable one or the strong one can feel like social fluency. It gives the group a shape. It gives the person a place. Everyone knows what to expect, which is one of the simplest ways ... Read more Read more ›

Psychology says people who are kind to everyone and close to no one often weren’t always this way — there was usually a friendship, a relationship, or a family dynamic that taught them, clearly enough to stick, that letting someone fully in was indistinguishable from handing them a way to hurt you

I once knew a man who was, without exaggeration, the most likeable person in any room. He remembered your dog’s name. He’d top up your drink before you noticed it was empty. Waiters adored him. Strangers left him feeling like the most interesting person alive. I knew him for eleven years and I could not ... Read more Read more ›

In homes common across the 1960s and 1970s, children learned to read a parent’s mood from the sound of the front door before anyone had spoken a word — researchers call the adult result hypervigilance, and it shows up in 5 recognisable patterns

My father learned to read a room before he learned to read a book.

In the first quarter of 2026, investors poured roughly $242 billion into AI startups—about 80% of all venture capital deployed worldwide, according to Crunchbase. Nothing comparable appears in its historical data: never before had one sector absorbed such a large share of global startup investment in a single quarter.

The first quarter of 2026 was not just another strong period for AI fundraising.

A 2025 MIT report estimated that roughly 95% of task-specific enterprise generative-AI initiatives had yet to produce measurable business returns. The researchers argued that the main obstacle was not the underlying models, but tools that failed to learn from feedback, fit existing workflows or solve clearly defined operational problems.

The useful reading of the MIT finding is not that generative AI has failed. It is that enterprise AI has run into the same old enterprise problem: a tool that does not fit the work is not made valuable by being technically impressive. The report in question has been widely identified as MIT NANDA’s The ... Read more Read more ›

There is a version of a good old age that most of us carry around without examining it. In it, an older person is comfortable, cared for, in reasonable health, and surrounded by people who love them. Money is not a worry. The phone rings on the right days, someone remembers the birthday, and the ... Read more Read more ›
