From Substack<\/a>: “The problem of unexploded ordnance (UXO) in Cambodia is a grave legacy of the Khmer Rouge period, with landmines and cluster munitions posing threats to the personal safety of people and communities, but also contaminating land that could otherwise be used for housing, agriculture and other infrastructure. After 25 years of demining, the dangers still persist, although incidences of death and injury have been falling over time. Apopo\u2019s mine-sniffing rats are a pivotal part of addressing this issue. These African rats are much larger, about the size of a cat, and can live for up to eight years. What makes these rats ideal for mine detection is their extraordinary sense of smell, which they use to detect explosives.”<\/p>\n\n\n\n

He passed himself off as an oil magnate and conned people out of billions<\/h2>\n\n\n\n

From the New Yorker<\/a>: “When she left, she passed by the couple\u2019s twin Mercedes-Benzes. She saw the men at a nineteen-twenties-themed club luncheon, wearing top hats and tailcoats. Turner seemed to especially relish dressing up and mingling with bigwigs. At one fund-raiser, he reportedly bought a table for ten thousand dollars, then raised his paddle at the auction and pledged a hundred thousand more.When the first heat of summer arrived, West Palm Beach emptied out. As soon as Maria returned, this past August, she called up Turner to arrange a drink. His number wasn\u2019t working, which seemed odd. Then one of her friends told her to Google \u201cAlan Todd May.\u201d Maria was soon staring at a mugshot: May, the man in the photo, was slimmer, and his hair was darker, but he was clearly the person she knew as Jacob Turner. He had escaped from a federal prison almost five years earlier, she read, while serving a twenty-year sentence for an oil fraud that had netted him millions.”<\/p>\n\n\n\n

She\u2019s a four-time Olympian but her parents want her to get a real job<\/h2>\n\n\n\n
\"\"\/<\/figure>\n\n\n\n

From the Wall Street Journal<\/a>: “Lily Zhang is the queen of American table tennis, a six-time national champ and four-time Olympian in the prime of her career. At only 28 years old, the California native can\u2019t help but dream ahead about playing in front of a home crowd at the 2028 Los Angeles Games. Her parents are less enthused. \u201cWe always try to convince her to stop playing,\u201d says her mother, Linda Liu. \u201cWe just want her to have a normal job.\u201d It turns out even the most decorated American of all time in her sport can\u2019t escape parental career pressure. Besides enduring frequent and unsolicited professional advice from Mom and Dad, what\u2019s most annoying to Zhang is that she concedes they have a point.”<\/p>\n\n\n\n

The Dunning-Kruger Effect probably doesn’t exist<\/h2>\n\n\n\n
\"\"\/<\/figure>\n\n\n\n

From McGill<\/a>: “I want the Dunning-Kruger effect to be real. First described in a seminal 1999 paper by David Dunning and Justin Kruger, this effect has been the darling of journalists who want to explain why dumb people don\u2019t know they\u2019re dumb. In a nutshell, the Dunning-Kruger effect was originally defined as a bias in our thinking. If I am terrible at English grammar and am told to answer a quiz testing my knowledge of English grammar, this bias in my thinking would lead me, according to the theory, to believe I would get a higher score than I actually would. In 2016 and 2017, two papers were published in a mathematics journal called Numeracy<\/em>. In them, the authors argued that the Dunning-Kruger effect was a mirage. And I tend to agree.”<\/p>\n\n\n\n

Summer on the Thames means the annual swan count led by the King’s Swan Marker<\/h2>\n\n\n\n
\"\"\/<\/figure>\n\n\n\n

From the BBC<\/a>: “The traditional counting of swans on the Thames is an annual summer spectacle, with brightly dressed teams of rowers going up the river, under the stewardship of the King’s Swan Marker, who wears a swan’s feather in his cap. This medieval ceremony now has a modern conservation purpose in monitoring the swan population, counting, weighing and measuring swans before releasing them back into the water. There were only 86 young swans found in a five-day search of the river between London and Oxfordshire, a 45% decline in two years. The King’s Swan Marker, David Barber, blamed catapults and air-gun shootings, as well as the ongoing impact of avian flu.”<\/p>\n\n\n\n

Scientists believe that babies emit a chemical that makes mothers more aggressive<\/h2>\n\n\n\n
\"\"\/<\/figure>\n\n\n\n

From Science<\/a>: “Researchers have identified an odorless compound emitted by babies called hexadecanal, or HEX, that appears to foster aggressive behavior in women and blunt it in men. \u201cWe cannot say that this is a pheromone,\u201d says study author Noam Sobel, a neuroscientist at the Weizmann Institute of Science. \u201cBut we can say that it\u2019s a molecule expressed by the human body that influences human behavior, specifically aggressive behavior, in a predicted manner.\u201dHumans emit HEX from their skin, saliva, and feces, and it\u2019s among the most abundant molecules babies emit from their heads. When researchers isolated the odorless compound and piped it into mouse cages, it had a relaxing effect on the animals, says Sobel, who studies the role of scent in human interactions.”<\/p>\n\n\n\n

In Basel, Switzerland people commute to work by floating down the river<\/h2>\n\n\n\n

Just found out that in the Swiss city of Basel, locals commute home from work by river.

They just put their belongings in a dry bag, jump in and float downstream.https:\/\/t.co\/UyMkP7Ue2a<\/a><\/p>— Today Years Old (@todayyearsoldig) August 4, 2024<\/a><\/blockquote>
