Playful Airline Safety Videos Could Be Making Passengers Less Safe

When you board a plane, chances are you want to stick your noise-canceling earphones in as soon as possible and pass out before the toddler in the row behind you starts screaming. Plus, if you’re a frequent traveler, you probably know the in-flight safety video by heart. Or do you? A survey published last month in the Journal of Travel Research reveals that not only did most participants fail an airline safety quiz immediately after watching the in-flight safety video, but that viewers of video

No Cheese Please

Libraries​ were all the rage in Renaissance Europe, and no wonder. Theatres of knowledge, grandly decorated and proudly displayed, they hosted dramas of many kinds. Learned men used them for lively conversation on such irresistible topics as the philosophies of Hermes, Zoroaster and Pythagoras or relations between the later Roman Empire and the Persian king Shapur II, which Angelo Poliziano, Pico della Mirandola and others debated in the new Florentine library of San Marco. Yet they were also –

72% of US teens have used AI companions, study finds

Hopefully not Grok’s companions … A new study by a U.S. nonprofit focused on the lives of kids and families, Common Sense Media, has found that a vast majority of U.S. teens (72%) have tried an AI companion at least once. By “companion,” the study is focused on AI chatbots that are designed for users to have more personal conversations with, not AI assistants that work as homework helpers, image generators, or voice assistants that just answer questions. For instance, the study’s definition of

Erythritol linked to brain cell damage and stroke risk

From low-carb ice cream to keto protein bars to "sugar-free" soda, the decades-old sweetener erythritol is everywhere. But new University of Colorado Boulder research shows the popular sugar substitute and specialty food additive comes with serious downsides, impacting brain cells in numerous ways that can boost risk of stroke. The study was published in the Journal of Applied Physiology. "Our study adds to the evidence suggesting that non-nutritive sweeteners that have generally been purport

Here’s how ChatGPT’s upcoming ‘Study Together’ tool could enhance learning (APK teardown)

Calvin Wankhede / Android Authority TL;DR OpenAI is working on a dedicated “Study Together” mode to help users grasp concepts better. Study Together is likely to help break down concepts into simpler terms and follow up with quizzes for more engaged learning. It is being tested with both free and paid users, suggesting non-paying users might also have access when it launches. AI tools, such as ChatGPT, have accelerated learning by making concepts much easier to find and summarize. Now, OpenA

Uranus Leaks More Heat Than We Thought

When Voyager 2 flew past Uranus in 1986, the spacecraft detected a surprisingly low level of internal heat from the planet. Since then, scientists believed Uranus to be the odd one out in our solar system’s family of giant planets—the others being Jupiter, Saturn, and Neptune—who all tend to emit more heat than they absorb from sunlight. Now, a new study suggests that scientists may have had the wrong idea about Voyager 2’s data: Uranus does have an internal heat source similar to its planetary

Published in the Nature Partnering Journal Aging, a new paper by researchers at Emory and Baylor's medical schools suggests that psilocybin, the active compound in psychedelic mushrooms — there are a range of species that produce it, but the best known is probably Pisolocybe cubensis — might extend the lifespans of both mi

Humans Are Starting to Talk More Like ChatGPT, Study Claims

For better or worse, the rise of ChatGPT as a writing tool, search engine, or conversational buddy has considerably changed how we communicate with each other and with technology. At the same time, ChatGPT’s widespread use has also sparked numerous online debates about whether it’s possible to spot AI-created content by looking at certain cues, like the em dash. But new research suggests that such AI cues might become increasingly harder to pick out—because we’re starting to speak more like Cha

8 Foods With Microplastics Hidden in Them and How to Limit Your Consumption

It's official: Microplastics are in more than just fish. They seem to be in everything now, even mundane things like chewing gum. UCLA researchers found that microplastics are released directly into our mouths each time we chew a piece. In addition to that, a new study published in Chemistry for Life tested 10 chewing gum brands and found every single one contained microplastics. With something as common as chewing gum becoming a delivery system for microplastics, many people are concerned abou

AI coding tools may not speed up every developer, study shows

Software engineer workflows have been transformed in recent years by an influx of AI coding tools like Cursor and GitHub Copilot, which promise to enhance productivity by automatically writing lines of code, fixing bugs, and testing changes. The tools are powered by AI models from OpenAI, Google DeepMind, Anthropic, and xAI that have rapidly increased their performance on a range of software engineering tests in recent years. However, a new study published Thursday by the non-profit AI research

AI coding tools can reduce productivity

The buzz about AI coding tools is unrelenting. To listen to the reports, startups are launching with tiny engineering teams, non-programmers are “vibe-coding” entire apps, and the job market for entry-level programmers is crashing. But according to a METR experiment conducted in the spring of 2025, there’s at least one cohort that AI tools still aren’t serving. METR performed a rigorous study (blog post, full paper) to measure the productivity gain provided by AI tools for experienced developer

Melting Glaciers Could Unleash a Barrage of Volcanic Eruptions Worldwide, Scientists Warn

As if we needed another reason to worry about the climate crisis, researchers have found that melting glaciers could trigger a surge of intense volcanic eruptions in the future. Across the globe, hundreds of subglacial volcanoes—formed by eruptions beneath glaciers—lie dormant under thick layers of ice. A new study, presented at the Goldschmidt Conference in Prague, suggests that these volcanoes could awaken as climate change accelerates glacier retreat, potentially leading to an increase in vo

ChatGPT is testing a mysterious new feature called ‘study together’

In Brief Some ChatGPT subscribers are reporting a new feature appearing in their drop-down list of available tools called “Study Together.” The mode is apparently the chatbot’s way of becoming a better educational tool. Rather than providing answers to prompts, some say it asks more questions and requires the human to answer, like OpenAI’s answer to Google’s LearnLM. Some also wonder whether it will have a mode where more than one human can join the chat in a study group mode. OpenAI did not r

ChatGPT is testing disruptive Study Together feature

OpenAI's "Study together" mode has been spotted in the wild, and it could help students prepare for exams directly from ChatGPT. We don't have the details yet, but references to ChatGPT Study Mode were first spotted in May, and testers noticed it widely earlier today. The Study together mode, which doesn't work right now, might allow students to either invite their friends to study on ChatGPT or have the AI act as a companion. We just don't know how it works yet, but it could disrupt the educ

Do You Really Learn When You Use AI? What MIT Researchers Found

Your brain works differently when you're using generative AI for a task than when you use your brain alone. Namely, you're less likely to remember what you did. That's the somewhat obvious-sounding conclusion of an MIT study that looked at how people think when they write an essay -- one of the earliest scientific studies of how using gen AI affects us. The study, a preprint that has not yet been peer-reviewed, is pretty small (54 participants) and preliminary, but it points toward the need for

New study offers clues about what makes someone cool

Is there a secret sauce that helps explain why people as different as David Bowie, Samuel L. Jackson and Charli XCX all seem so self-assured and, well, cool? A new study suggests that there are six specific traits that these people tend to have in common: Cool people are largely perceived to be extroverted, hedonistic, powerful, adventurous, open and autonomous. The study, which was published on Monday in the Journal of Experimental Psychology: General, surveyed nearly 6,000 participants from

Air pollution may contribute to development of lung cancer in never-smokers

Now, a study published on July 2 in Nature has uncovered compelling genomic evidence that points to air pollution—and other environmental exposures—as a potential major factor behind this growing public health concern. The study was jointly led by researchers at the University of California San Diego and the National Cancer Institute (NCI), part of the National Institutes of Health (NIH). “We’re seeing this problematic trend that never-smokers are increasingly getting lung cancer, but we haven’

We Found the 8 Most Common Foods With Microplastics

Microplastics are the latest hidden hazard worry for the world -- and now they've even been found in chewing gum. UCLA researchers have found that every time we chew gum, microplastics are released directly into our mouths. In addition to that, a new study published in Chemistry for Life tested 10 chewing gum brands and found every single one contained microplastics. This was found to be the case with both natural and synthetic varieties. A gram of gum releases around 100 microplastics on averag

Teen drivers spend 21% of the time looking at their phones, reveals alarming study [Video]

A alarming new study has found that som teen drivers in the US spend as much as 21% of their time at the wheel looking at their phones, creating a substantial risk of distracted driving crashes. While much of this was brief glances, more than 5% of driving time comprised looking at their phone for 2+ seconds a time, long enough to qualify as dangerous … CNET reports that the teens did this despite understanding the risks they are taking. The study includes survey responses from 1,126 teen dri

Scary Survey Results: Teen Drivers Are Often Looking at Their Phones

A new study reveals that teen drivers in the US are spending more than one-fifth of their driving time distracted by their phones, with many glances lasting long enough to significantly raise the risk of a crash. Published in the journal Traffic Injury Prevention and released on Thursday, the research found that, on average, teens reported looking at their phones during 21.1% of every driving trip. More than a quarter of those distractions lasted two seconds or longer, which is an amount of time

What Happens to Your Brain When You Use ChatGPT? Scientists Took a Look
