The average credit card APR is ~21%
The average credit card APR is sitting around 21% right now, according to the Fed, which is kind of wild when you stop and actually think about it.
At that rate a balance barely moves on minimum payments. A $10,000 balance at 21%, paying $250 a month, is about 6 years and roughly $7,400 in interest. The math punishes carrying a balance far more than any single purchase ever does.
Most people just treat the rate as background noise instead of the real problem. A balance transfer, a lower-rate loan, or borrowing against something you already own can all bring that rate down.
Curious how everyone else is handling it. If you are carrying a balance, are you attacking the rate or just the balance?

A candidate aced the video interview, cleared the background check, and deployed malware on day one
Jones Walker, a national law firm, documented this scenario in detail and it's not theoretical. A hire looked legitimate at every stage. Polished resume, credible interview, passed screening. Then on day one they had system access and used it.
What makes this particularly hard to defend against is that the background check wasn't wrong. The identity documents were real, just stolen. The fraud happened upstream of the check itself, at the identity and credential layer.
It's one of the cleaner illustrations of why hiring verification has to go deeper than it used to.

A coral grouper that loses prey into a crevice will swim tens of meters across the reef to find a specific moray eel it has hunted with successfully before, then shake its head at the hole until the eel follows it back. The behavior meets the same criteria used to test great ape gestures.

China's first humanoid police robot went on traffic duty in Wuhu in January 2026 with an official badge number — "Intelligent Police Unit R001." By May, Hangzhou had a 15-robot squadron working downtown intersections, with published service stats down to 647.7 hours.

The only significant habitable land on Earth claimed by no country isn't unclaimed by accident — Egypt and Sudan each refuse it, because the border line that would give them Bir Tawil is the same line that would cost them a Red Sea coastal triangle ten times more valuable.

In 1876 fresh meat fell from a cloudless sky in Kentucky. Microscopists found lung, cartilage, and striated muscle from several different animals, with no digestive contents. The answer is vulture kettles — and it points at something bigger: the sky is a loaded biological transport system.

One in three Americans, or around 70 to 100 million, have criminal records
Saw this statistic the other day that one in three Americans have criminal records, according to The Sentencing Project.
Of course many of these criminal records are not as severe as people assume. A significant portion are misdemeanors, old offenses, or arrests that never led to a conviction. But they can still show up on a background check and affect someone's ability to get hired.
For employers, this is worth thinking about. Automatically disqualifying anyone with a record means ruling out a huge portion of the workforce, often for something that has no bearing on the role they're applying for. The better approach is looking at the nature of the offense, how long ago it happened, and whether it's actually relevant to the job.

San Francisco's white-crowned sparrows sing in 18 distinct neighborhood dialects — Presidio, Lake Merced, Marin Headlands — some only a few hundred meters apart. Females prefer their local accent when choosing mates & a 2024 study found adjacent neighborhoods are genetically diverging as a result.

About 40% of therapists earn money outside of client sessions
About 40% of therapists in a 2026 report earn income from at least one source outside their practice. Supervision (16.1%) and consulting (12.6%) lead the list, followed by teaching (10.7%), speaking (10.5%), coaching (7.8%), and writing (4.1%).
Session income is capped by the number of hours you're willing to sit in the chair, with the median caseload being 18 clients a week.
What's less clear from survey data is which of these streams pay comparably once you account for prep and admin.
Therapists, does this data look similar to what you’re seeing in your practice?

Palm Jumeirah has no concrete foundation — it's 94 million m³ of dredged marine sand behind a rock breakwater. It sinks ~5mm/year, loses sand continuously to wave action, and one replenishment operation moved 3.5 million m³. Dredging also buried the coral reef that used to dissipate the wave energy.

A 1,400-lb wheel of cheddar sat aging in the White House entrance hall for 2 yrs, reportedly smellable from blocks away. In 1837 Andrew Jackson invited the public in to eat it. Thousands came, finished it in 2 hours & ground it into the carpets. The next admin had to whitewash the East Room.

A crypto company CEO bought RealDoll in 2024, reverse-merged it into a public shell & now sells $20,000 animatronic companions with magnetic swappable faces. Meanwhile Boston Dynamics, Tesla, Figure, and every other major humanoid maker has committed to never entering the romantic companion market.

The average mortgage-holding homeowner has ~$302k equity
The average homeowner with a mortgage has roughly $302,000 in equity.
A ton of net worth is locked in the walls of the house, even while a lot of the same households carry high-interest debt on the other side of the ledger.
It seems worth at least knowing the number and understanding the options, from HELOCs to home equity loans to the newer card-style lines, before sticking to a 20%+ credit card.
Homeowners, how much home equity do you have?

Gaddafi's Great Man-Made River in Libya pumps 6.5M cubic meters/day of Ice Age water that has zero recharge — 70% of the country's freshwater. The aquifer is shared with Egypt, Chad, and Sudan, with no coordination, no metering, and no enforcement. Depletion estimates range from 60 years to 1,000.

Mount Athos has banned women — and female animals — since 1046. It sits inside the EU, and EU gender equality law does not apply there: the 1981 Greek accession treaty specifically exempted it. The European Parliament asked Greece to lift the ban in 2003. Greece declined.

Thieves drained $18M of syrup from Quebec's strategic maple reserve, refilling the barrels with water so they'd still weigh 620 lbs at the annual audit. Canada's Supreme Court fined the ringleader $9,171,397.57 — the gross he handled, not the $1M he kept after paying his accomplices.

The 1908 Tunguska airburst flattened 80 million trees and left no crater — the asteroid detonated 5-10 km up and never touched the ground. That size class, a few tens of meters, is exactly the one our surveys miss. Chelyabinsk arrived out of the sun in 2013 with zero telescopes tracking it.
