It's not all Pepes and trollfaces - memes can be a force for good - The Verge - 0 views

    "How the 'emotional contagion' of memes makes them the internet's moral conscience By Allie Volpe Aug 27, 2018, 11:30am EDT Illustration by Alex Castro & Keegan Larwin SHARE Newly single, Jason Donahoe was perusing Tinder for the first time since it started integrating users' Instagram feeds. Suddenly, he had an idea: follow the Instagram accounts of some of the women he'd been interested in but didn't match with on the dating service. A few days later, he considered taking it a step further and direct messaging one of the women on Instagram. After all, the new interface of the dating app seemed to encourage users to explore other areas of potential matches' online lives, so why not take the initiative to reach out? Before he had a chance, however, he came across the profile of another woman whose Tinder photo spread featured a meme with Parks and Recreation character Jean-Ralphio Saperstein (Ben Schwartz) leaning into the face of Ben Wyatt (Adam Scott) with the caption: hey I saw you on Tinder but we didn't match so I found your Instagram you're so beautiful you don't need to wear all that makeup ahah I bet you get a lot of creepy dm's but I'm not like all those other guys message me back beautiful btw what's your snap "I was like, 'Oh shit, wow,'" Donahoe says. Seeing his potential jerk move laid out so plainly as a neatly generalized joke, he saw it in a new light. "I knew a) to be aware of that, and b) to cut that shit out … It prompted self-reflection on my part." THE MOST SUCCESSFUL MEMES STRIKE A CULTURAL CHORD AND CAN GUIDE AND EVEN INFLUENCE BEHAVIOR Donahoe says memes have resonated with him particularly when they depict a "worse, extreme version" of himself. For Donahoe, the most successful memes are more than just jokes. They "strike a societal, cultural chord" and can be a potent cocktail for self-reflection as tools that can guide and even influence behavior. In the months leading up to the 2016 US

    "With each interaction, Alexa is training to hear better, to interpret more precisely, to trigger actions that map to the user's commands more accurately, and to build a more complete model of their preferences, habits and desires. What is required to make this possible? Put simply: each small moment of convenience - be it answering a question, turning on a light, or playing a song - requires a vast planetary network, fueled by the extraction of non-renewable materials, labor, and data. The scale of resources required is many magnitudes greater than the energy and labor it would take a human to operate a household appliance or flick a switch. A full accounting for these costs is almost impossible, but it is increasingly important that we grasp the scale and scope if we are to understand and govern the technical infrastructures that thread through our lives. III The Salar, the world's largest flat surface, is located in southwest Bolivia at an altitude of 3,656 meters above sea level. It is a high plateau, covered by a few meters of salt crust which are exceptionally rich in lithium, containing 50% to 70% of the world's lithium reserves. 4 The Salar, alongside the neighboring Atacama regions in Chile and Argentina, are major sites for lithium extraction. This soft, silvery metal is currently used to power mobile connected devices, as a crucial material used for the production of lithium-Ion batteries. It is known as 'grey gold.' Smartphone batteries, for example, usually have less than eight grams of this material. 5 Each Tesla car needs approximately seven kilograms of lithium for its battery pack. 6 All these batteries have a limited lifespan, and once consumed they are thrown away as waste. Amazon reminds users that they cannot open up and repair their Echo, because this will void the warranty. The Amazon Echo is wall-powered, and also has a mobile battery base. This also has a limited lifespan and then must be thrown away as waste. According to the Ay

How Neuroscience Can Help Us Treat Trafficked Youth - Pacific Standard - 0 views

  • A common misconception is that these youths are choosing to engage in the commercial sex trade. But as recent advances in neuroimaging techniques help scientists unravel the myriad ways that trauma affects the brain, emerging evidence suggests that brain changes resulting from trauma could make young people more vulnerable to exploiters and less receptive to people trying to help. Rather than making a conscious decision to rebel, these kids are simply doing their best to survive, using the adaptive strategies that their brains developed in response to a perilous world.
  • Though the human brain is adaptable throughout life, adaptability is greatest during childhood, as the developing brain responds to the surrounding environment. Survival is the brain's top priority. Young people growing up in dangerous environments will develop brains that are highly responsive to threat cues. In particular, recent studies show that children who have experienced trauma exhibit drastic changes in their amygdala, an area of the brain wired to identify signs of danger.
  • Besides the amygdala, another brain region affected by trauma is the hippocampus, an area involved with contextual learning and memory. The hippocampus takes context into account, so that a person can appropriately respond to the same cues in different situations. For instance, most people would respond differently to hearing gunfire in a shooting range than they would to hearing gunfire in an airport.

  • McLaughlin's research shows that youth who have experienced trauma have a smaller hippocampus than those who haven't, and are less able to take context into account when they detect a threat cue. When McLaughlin presented images of faces embedded in real-world scenes to kids, those with a history of trauma exhibited less activity in their hippocampus while viewing angry facial expressions. And when given a memory test afterward, they were less able to remember scenes in which they'd identified people displaying anger.
  • Because the brain remains malleable throughout life, it's never too late to mitigate the effects of trauma, McLaughlin says. There are a variety of evidence-based treatments that have proven effective in alleviating the mental-health consequences of trauma. For example, the technique of cognitive reappraisal, a cornerstone of Trauma-Focused Cognitive Behavioral Therapy, can help victims better regulate their emotions by changing the way they view a distressing situation. They can try to imagine that the situation is occurring far away from them, or that they are viewing the event from a removed perspective, as though watching a movie screen. When McLaughlin taught such techniques to young people in her lab, they were able to decrease their emotional reactivity as well as their amygdala response to negative stimuli.

Accounting for the gaps in ancient food webs - 0 views

  •  
    If you want to understand an ecosystem, look at what the species within it eat. In studying food webs-how animals and plants in a community are connected through their dietary preferences-ecologists can piece together how energy flows through an ecosystem and how stable it is to climate change and other disturbances. Studying ancient food webs can help scientists reconstruct communities of species, many long extinct, and even use those insights to figure out how modern-day communities might change in the future. There's just one problem: only some species left enough of a trace for scientists to find eons later, leaving large gaps in the fossil record-and researchers' ability to piece together the food webs from the past.
