Put down Wordle. New brain-exercise-for-the-day just dropped. Can you read 900 words per minute? a viral post that has been doing the rounds on X, challenges. Try it. If you made it to 600 words per minute, thats more than twice the speed of the average reader. If you made it to 900, congratulationsaccording to some back-of-the-napkin math, that makes you 278% faster than the national average (which is 238 words per minute). By that same logic, it could take you around 40 seconds to read this 600ish word article. But should it? As one X user pointed out, this is like brainrot for reading. Or as Jane Ollis, medical biochemist and founder at AI-powered neurotech company Sona, told Fast Company, Its the cognitive equivalent of watching Netflix on fast-forward. The challenge uses a technique called rapid sequential visual presentation, or RSVP. The effect is bizarre, almost meditative, as your eyes passively absorb huge quantities of words at a rapid-fire pace. Eye movements shorten, the inner voice gets kicked out of the room, and the brain starts guessing what comes next, explains Ollis. There’s another factor to consider when we read really fast. Its neural autocomplete, says Ollis. Very efficient. Not always accurate. Research backs this up. Getting rid of sub-vocalizationsor hearing words in your mindmay increase reading speed, but has been shown to reduce comprehension of what is being read. And doing away with those extra eye movements, by placing words one on top of another rather than along a sentence (like in the X post), has also been found to have a similar effect on comprehension. You know roughly what happened, but you wouldnt bet your reputation on the details. And neuroscience tells us that the good stuffinsight, memory, and learninghappens when the brain slows down enough to actually chew the information, explains Ollis. When people try to read at extreme speed, the brain doesnt suddenly get smarter. It gets lazier in a clever way. For the deluge of text we consume on a daily basis (more than at any other time in history) this skill isnt unhelpful. From checking emails to scanning work documents to perusing social feeds, these are all effective use-cases for this kind of speed reading approach. (Its also a pretty fun challenge, to be honest.) But the best way to read faster, without reducing comprehension, is simply to read more. In a world obsessed with speed, Ollis says, attention might be the most rebellious skill we have.

When you think of tools for studying substance use and addiction, a social media site like Reddit, TikTok, or YouTube probably isnt the first thing that comes to mind. Yet the stories shared on social media platforms are offering unprecedented insights into the world of substance use. In the past, researchers studying peoples experiences with addiction relied mostly on clinical observations and self-reported surveys. But only about 5% of people diagnosed with a substance use disorder seek formal treatment. They are only a small sliver of the population who have a substance use disorderand until recently, there has been no straightforward way to capture the experiences of the other 95%. Today, millions of people openly discuss their experiences with drugs online, creating a vast collection of raw narratives about drug use. As a doctoral student in information science with a background in public health, I use this material to better understand how people who use drugs describe their lives and make sense of their experiences, especially when it comes to stigma. These online conversations are reshaping how researchers think about substance use, addiction, and recovery. Advances in artificial intelligence are helping make sense of these conversations at a scale that wasnt possible before. The hidden population The vast majority of people diagnosed with a substance use disorder address the issue informallyseeking support from their community, friends, or family, self-medicating or doing nothing at all. But some choose to post about their drug use in dedicated online communities, such as group forums, often with a level of candor that would be difficult to capture in clinical interviews. Their social media posts offer a window into real-time, unscripted conversations about substance use. For example, Reddit, which is comprised of topical communities called subreddits, contains over 150 interconnected communities dedicated to various aspects of substance use. In 2024, my colleagues and I analyzed how participants in drug-related forums on Reddit connect and interact. We found that they focused on the chemistry and pharmacology of substances, support for drug users, recreational experiences such as festivals and book clubs, recovery help, and harm reduction strategies. We then selected a few of the most active communities to develop a system for categorizing different types of personal disclosures by labeling 500 Reddit posts. Policymakers and public health experts have expressed concerns that social media encourages risky drug use. Our work did not assess that issue, but it did support the notion that platforms such as Reddit and TikTok often serve as a lifeline for people seeking just-in-time support when they need it most. When we used machine learning to analyze an additional 1,000 posts, we found that most users in the forums we focused on were seeking practical safety information. Posters often posed questions such as how much of a substance is safe to take, what interactions to avoid and how to recognize signs of trouble. We observed that these forums function as informal harm reduction spaces. People share not just experiences but warnings, safety protocols and genuine care for each others well-being. When community members are lost to overdose, the responses reveal deep grief and renewed commitments to keeping others safe. This is the everyday reality of how people navigate substance use outside medical settingswith far more nuance and mutual support than critics might expect. We also explored TikTok, analyzing more than 350 videos from substance-related communities. Recovery advocacy content was the most common, depicted in 33.9% of the videos we analyzed. Just 6.5% of the videos showed active drug use. On Reddit, we frequently saw people emphasizing safety and care. Why AI is a game-changer Platforms like Reddit, TikTok, and YouTube host millions of posts, videos, and comments, many filled with slang, sarcasm, regional language, or emotionally charged stories. Analyzing this content manually is time-consuming, inconsistent, and virtually impossible to do at scale. Thats where AI comes in. Traditional machine learning approaches often rely on fixed word lists or keyword matching, which can miss important contextual cues. In contrast, newer modelsespecially large language models like OpenAIs GPT-5are capable of understanding nuance, tone, and even the underlying intent of a message. This makes them especially useful for studying complex issues like drug use or stigma, where people often communicate through implication, coded language, or emotional nuance rather than direct statements. These models can identify patterns across thousands of posts and flag emerging trends. For example, researchers used them to detect shifts in how Canadians on X, the social media site formerly called Twitter, discussed cannabis as legalization approachedcapturing shifts in public attitudes that traditional surveys might have missed. In another study, researchers found that monitoring Reddit discussions can help predict opioid-related overdose rates. Official government data, like that from the Centers for Disease Control and Prevention, typically lags by at least six months. But adding near-real-time Reddit data to forecasting models significantly improved their ability to predict overdose deathspotentially helping public health officials respond faster to emerging crises. The role that stigma plays in substance use disorder is difficult to capture in traditional surveys and interviews. Bringing stigma into focus One of the most difficult aspects of substance use to studyand to addressis the stigma. Its deeply personal, often invisible and shaped by a persons identity, relationships, and environment. Researchers have long recognized that stigma, especially when internalized, an erode self-worth, worsen mental health, and prevent people from seeking help. But its notoriously hard to capture using traditional research methods. Most clinical studies rely on surveys or interviews conducted at regular intervals. While useful, these snapshots can miss how stigma unfolds in everyday life. Stigma scholars have emphasized that understanding its full impact requires paying attention to how people talk about themselves and their experiences over time. On social media platforms, people often discuss stigma organically, in their own words and in the context of their lived experiences. They might describe being judged by a health care provider, express shame about their own substance use or reflect on how stigma shapes their relationships. Even when posts arent directly naming the experience as stigma, they still reveal how stigma is internalized, challenged or reinforced. Using large language models, researchers can begin to track these patterns at scale, identifying linguistic signals like shame, guilt or expressions of hopelessness. In recent work, my colleagues and I showed that stigma expressed on Reddit aligns closely with long-standing stigma theorysuggesting that what people share on social media reflects recognizable stigma processes, not something fundamentally new or separate from what researchers have long studied. That matters because stigma is one of the most significant barriers to treatment for people with substance use disorder. Understanding how people who use drugs talk about stigma, harm, recovery, and survival, in their own words, can complement surveys and clinical studies and help inform better public health responses. By taking these everyday expressions seriously, researchers, clinicians and policymakers can begin to respond to substance use as it is actually lived messy, evolving and deeply human.

Big city or small town? Tourist trap or undiscovered sights? Following an itinerary or spontaneous exploring? Travel has become a trend as generations raised on social media catch flights, not feelings. But Gen Z and millennials may also be redefining travelall in the search of a more authentic adventure. Hidden-gem locations and no-stress getaways are top of the list for young travelers. Its a shift from the kinds of bucket-list destinations that have saturated Instagram and TikTok and fueled an overtourism crisis in recent years. As traveler-favorite towns are combatting high influxes of visitors, some travelers are looking to new horizons. Theyre also looking to AI to help plan trips. Rather than ask friends or scroll the social media feed, young travelers are turning to the technology for destination suggestions and deals. Travel search engine company Kayak looked into the vacation trends of the future as younger generations jet set. Here are some of the top findings. Hidden gems The days of TikTok-planned itineraries may be waning, as posts with the #hiddengem hashtag increased by at least 50%. Sixty-nine percent of Gen Z and 66% of millennials say they want to visit places theyve never seen before, according to Kayak’s 2026 WTF What the Future report. Young travelers are searching for hidden gems (and the ability to claim they discovered them first). Influencers and travel gurus are quick to offer suggestions of their favorite underground vacation spots. So where are young travelers headed? Check out some of the emerging destinations, as highlighted in Kayak’s report: Cork, Ireland Fez, Morocco Sofia, Bulgaria Praia, Cape Verde Baku, Azerbaijan Chongqing, China Asunción, Paraguay Barranquilla, Colombia Halifax, Canada Norfolk, VA Slow travel Beyond just looking for the next undiscovered dream vacation spot, younger travelers are increasingly looking for ways to actually unwind on holiday. Where trips used to be about seeing every sight imaginable, TikTok creators are now promoting so-called slow travel. Sixty-six precent of travelers say relaxation and mental reset are their top priorities on a trip, according to Kayak’s report. So what does slow travel entail? It might encapsulate a few trends: shorter trips, looser itineraries, and focusing on wellness. Younger generations are certainly exercising their wanderlust, but theyre doing it at their speedand in a dream location they might be gatekeeping.
