men found it more appealing if their committed romantic/sexual partners frequently changed their physical appearance, while women reported that they modified their physical appearance more frequently than did men, potentially appealing to male desires for novelty
I examine the relationship between unhappiness and age using data from eight well-being data files on nearly 14 million respondents across forty European countries and the United States and 168 countries from the Gallup World Poll. [...] Unhappiness is hill-shaped in age and the average age where the maximum occurs is 49 with or without controls. [Journal of Economic Behavior & Organization]
A large empirical literature has debated the existence of a U-shaped happiness-age curve. This paper re-examines the relationship between various measures of well-being and age in 145 countries. [...] The U-shape of the curve is forcefully confirmed, with an age minimum, or nadir, in midlife around age 50 in separate analyses for developing and advanced countries as well as for the continent of Africa. The happiness curve seems to be everywhere. [Journal of Population Economics ]
When we lose weight, where does it go? The correct answer is that fat is converted to carbon dioxide and water. You exhale the carbon dioxide and the water mixes into your circulation until it’s lost as urine or sweat. [...] This surprises just about everyone, but actually, almost everything we eat comes back out via the lungs. Every carbohydrate you digest and nearly all the fats are converted to carbon dioxide and water. The same goes for alcohol. Protein shares the same fate, except for the small part that turns into urea and other solids, which you excrete as urine. The only thing in food that makes it to your colon undigested and intact is dietary fibre (think corn). Everything else you swallow is absorbed into your bloodstream and organs and, after that, it’s not going anywhere until you’ve vaporised it. [The Conversation]
Moringa oleifera, an edible tree found worldwide in the dry tropics, is increasingly being used for nutritional supplementation. Its nutrient-dense leaves are high in protein quality, leading to its widespread use by doctors, healers, nutritionists and community leaders, to treat under-nutrition and a variety of illnesses. Despite the fact that no rigorous clinical trial has tested its efficacy for treating under-nutrition, the adoption of M. oleifera continues to increase. The “Diffusion of innovations theory” describes well the evidence for growth and adoption of dietary M. oleifera leaves, and it highlights the need for a scientific consensus on the nutritional benefits. [...] The regions most burdened by under-nutrition, (in Africa, Asia, Latin America, and the Caribbean) all share the ability to grow and utilize an edible plant, Moringa oleifera, commonly referred to as “The Miracle Tree.” For hundreds of years, traditional healers have prescribed different parts of M. oleifera for treatment of skin diseases, respiratory illnesses, ear and dental infections, hypertension, diabetes, cancer treatment, water purification, and have promoted its use as a nutrient dense food source. The leaves of M. oleifera have been reported to be a valuable source of both macro- and micronutrients and is now found growing within tropical and subtropical regions worldwide, congruent with the geographies where its nutritional benefits are most needed. Anecdotal evidence of benefits from M. oleifera has fueled a recent increase in adoption of and attention to its many healing benefits, specifically the high nutrient composition of the plants leaves and seeds. Trees for Life, an NGO based in the United States has promoted the nutritional benefits of Moringa around the world, and their nutritional comparison has been widely copied and is now taken on faith by many: “Gram for gram fresh leaves of M. oleifera have 4 times the vitamin A of carrots, 7 times the vitamin C of oranges, 4 times the calcium of milk, 3 times the potassium of bananas, ¾ the iron of spinach, and 2 times the protein of yogurt” (Trees for Life, 2005). Feeding animals M. oleifera leaves results in both weight gain and improved nutritional status. However, scientifically robust trials testing its efficacy for undernourished human beings have not yet been reported. If the wealth of anecdotal evidence (not cited herein) can be supported by robust clinical evidence, countries with a high prevalence of under-nutrition might have at their fingertips, a sustainable solution to some of their nutritional challenges. [...] The “Diffusion of Innovations” theory explains the recent increase in M. oleifera adoption by various international organizations and certain constituencies within undernourished populations, in the same manner as it has been so useful in explaining the adoption of many of the innovative agricultural practices in the 1940-1960s. [...] A sigmoidal curve (Figure 1), illustrates the adoption process starting with innovators (traditional healers in the case of M. oleifera), who communicate and influence early adopters, (international organizations), who then broadcast over time new information on M. oleifera adoption, in the wake of which adoption rate steadily increases.[Ecology of Food and Nutrition]
There is a widespread stereotype that women are better at multitasking. The present study examined a possibility that men were better at concurrent multitasking while women were better at task switching. Findings suggest that men have an advantage in concurrent multitasking.

We examine the threat to individuals’ privacy based on the feasibility of reidentifying users through distinctive profiles of their browsing history visible to websites and third parties. We then find that for users who visited 50 or more distinct domains in the two-week data collection period, ~50% can be reidentified using the top 10k sites. Reidentifiability rose to over 80% for users that browsed 150 or more distinct domains. [PDF]

Bell Labs itself later grew to be one of the marquees of commercial labs—in the late 1960s it employed 15,000 people including 1,200 PhDs, who between them made too many important inventions to list, from the transistor and the photovoltaic cell to the first digitally scrambled voice audio (in 1943) and the first complex number calculator (in 1939). Fourteen of its staff went on to win Nobel Prizes and five to win Turing Awards.

EncroChat was a Europe-based communications network and service provider allegedly used by organized crime members to plan criminal activities. Police infiltrated the network between at least March and June 2020 during a Europe-wide investigation. [...] At least 800 arrests have been made across Europe as of 7 July 2020. [...] The Dutch police arrested more than 100 suspects and seized more than 8 tonnes of cocaine, around 1.2 tonne of crystal meth, 19 synthetic drug laboratories, dozens of guns and luxury cars, and around €20 million in cash. In a property in Rotterdam, authorities found police uniforms, stolen vehicles, 25 firearms and drugs. On 22 June 2020 the Dutch police discovered a "torture chamber" in a warehouse.

Attachment theory is an enduring and generative framework for understanding infant and romantic relationships. Here, I advance a two-system approach to attachment, proposing that infant attachments and romantic attachments constitute etiologically distinct systems that evolved in response to different selection pressures, serve different evolutionary functions, and are fundamentally different in nature with regard to operation and necessity toward their respective evolutionary goals.

[A]utomated facial recognition is still in its infancy and many countries rely on humans to do the job. But not just any humans—people with a rare ability to accurately recognize faces in CCTV footage regardless of the angle, or how grainy or fleeting the image. The term “super recognizer” first appeared in 2009 and describes people who can remember more than 80 percent of the faces of people they meet (the average is 20 percent). The neural-mechanism behind super recognition is still largely unknown, but the skill seems to be genetic and possessed by only about one percent of the population. [...] Are you always accurate? Yes, 100 percent. You don’t have a situation where you go, “I think that might be matey from my old job”. It’s really solid and definite. [...] I can recognize people from behind as well, the back of their heads. I think I’m recognizing a shape. There are various elements, different super recognizers might say they can tell who somebody is from their jawline. We’re mostly like that, we don’t need to see the full face. [...] if any of your readers think they’re like me and might be good at it, they should do the test online. [Vice]

Studies are showing that the novel coronavirus can be detected in stool samples and anal swab samples for weeks. In fact, scientists are testing wastewater as an early tracking system for outbreaks. And a recent case on an airplane identified the airplane bathroom as the potential source. When you flush a toilet, the churning and bubbling of water aerosolizes fecal matter. That creates particles that will float in the air, which we will now politely call “bioaerosols” for the rest of this article. [...] Take one 2018 study of flushing toilets in a hospital. Researchers found high concentrations of bioaerosols when a toilet with no lid was flushed. [...] When you flush the toilet, you’re breathing in toilet water, and whatever is in that toilet water — including viruses and bacteria. [Washington Post]

A strange phenomenon has emerged near Amazon.com Inc. delivery stations and Whole Foods stores in the Chicago suburbs: smartphones dangling from trees. Contract delivery drivers are putting them there to get a jump on rivals seeking orders, according to people familiar with the matter. Someone places several smartphones in a tree located close to the station where deliveries originate. Drivers in on the plot then sync their own phones with the ones in the tree and wait nearby for an order pickup. [update 9/5: Amazon Drivers Say Smartphones-In-Trees Scheme Has Been Thwarted ]

The nine alternative visions of chess that AlphaZero tested included no-castling chess, which Kramnik and others had already been thinking about. Five of the variants altered the movement of pawns, including torpedo chess, in which pawns can move up to two squares at a time throughout the game, instead of only on their first move. Draws were less common under no-castling chess than under conventional rules. And learning different rules shifted the value AlphaZero placed on different pieces: Under conventional rules it valued a queen at 9.5 pawns; under torpedo rules the queen was only worth 7.1 pawns. A more extreme change, self-capture chess, in which a player can take their own pieces, proved even more alluring. [Wired]
