Textbooks are often deemed authoritative sources of information necessary for education. These learning materials include the latest scientific findings to reflect societal changes and show how knowledge has grown over time. They play a critical role in how educators tackle certain topics to educate their students in classroom settings.
According to a 2016 policy paper from the United Nations Educational, Scientific and Cultural Organization (UNESCO), formal schooling is the primary approach to address environmental challenges. Since curricular content has been shown to influence students’ knowledge of environmental issues, it’s essential to analyze how textbooks frame and discuss the pressing issue of climate change.

Your heart beats around 100,000 times every day. Heart rate is a key marker of cardiovascular activity and an important vital sign. But your pulse is not as steady as a precision clock – nor would you want it to be.
As a cardiovascular physiologist, I measure heart rate in nearly every experiment my students and I perform. Sometimes we use an electrocardiogram, such as you’d see in a medical clinic, which uses sticky electrodes to measure electrical signals between two points of your body. Other times we use a chest strap monitor, like ones you might see on someone at the gym, which also detects heartbeats based on electrical activity.

S17Is my child too young for social media?
Through these accounts – on sites including Facebook, Instagram, Snapchat, TikTok, Twitch, Twitter and YouTube, which typically allow accounts from age 13 (except for Snapchat, which allows from age 11) – children were exposed to almost two-thirds more age-restricted ads than under 17s who set up their profiles with their actual age.

S21 S20 S39The history of ice, one of the first luxuries
The first recorded icehouse dates to Year 13 of the rule of Shulgi, King of all Sumer and Akkad, builder of the Great Ziggurat of Ur, a date which would, by our reckoning, fall somewhere around 2081 b.c.e. We know the icehouse was a big deal because the Sumerians like to name each year after something significant that happened within it. Year 13 was the year of the icehouse. It is described in the surviving cuneiform tablets as being twice as long as it was deep, and insulated with branches of tamarisk.
What we cannot know is whether this was Shulgi’s innovation, or whether ice pits had been built previously, perhaps even before the founding of the Sumerian civilization. But if it was his or his engineer’s idea, it would take more than 4,000 years for the use of ice to become as unremarkable as it is today. Yet historical sources for it remain limited perhaps because, even then, it seemed ordinary.

S46The Economy’s Fundamental Problem Has Changed
For years, Americans couldn’t afford to buy things. Now there aren’t enough things to buy.
A few weeks ago, I was buying an iced coffee near my home in San Francisco. I went to pay with cash, and the barista asked me to pay with Apple Pay or a card—she could give me back bills, but did not have any coins.

S16For Marginalized Chefs, Are Pop-Ups the Path to Success?
Most meals don’t come with a thesis statement, but at the Shifting the Lens series, a chef-in-residence program focusing on chefs of color, there’s no eating without considering exactly what the chefs in charge have to say. For chef Preeti Mistry, who helped conceptualize the series with J Vineyards, developing Shifting the Lens was a way to center chefs of color who put their values and politics at the forefront of their work, but who may not have their own restaurant at which to showcase their talents. “There was a lot of talk going on about AAPI hate last year, and violence, and wanting to ... actually be proactive in talking about change,” Mistry says. By presenting cuisine that has not traditionally been championed in a fine dining, wine-tasting setting, Mistry hopes to challenge people’s expectations about cuisine — and the people who make it.

S3The best things we bought in 2022
So you’re flush with gift cards and $5 checks from grandparents but aren’t sure what in the wild world of e-commerce is noice and what’s noise. Luckily, the PopSci staff is always searching for tech toys that live up to the hype. One of the perks of the job is we get to go hands-on with a ton of stuff every year, so when something stands out it’s either really dope or truly helps us cope. Eager to share our personal discoveries with equally passionate gadget geeks, we’ve put together this short list of our No. 1 purchases in 2022 so you can shop for the best things with confidence.
Fellow’s maximized minimalism designer accessories aesthetic has become iconic in barista circles (and corners), and for good reason. This electric kettle, available in multiple finishes, sits on a minimalist base equipped with a 1200-watt quick-heating element and coin-shaped sleek LCD screen so you can quickly dial in to-the-degree temperature/set a brew stopwatch for the coffee-brewing method/tea type you’re using. And the gooseneck spout allows for precise saturation. The standard edition is a proven workhorse, but I recommend you go all-in and splurge on this newer Pro edition. For an extra $30, it adds a high-resolution color LCD, plus more scheduling options/guide modes/temperature hold time adjustments (Wi-Fi upgradeable if/when new features get released). I’ve found it invaluable as my mood swings like a jittery overcaffeinated pendulum between pour-overs and French press coffee, oolong and Earl Grey teas. — Tony Ware, associate managing editor, gear and reviews

S47The Great Big Medicare Rip-Off
When President Lyndon B. Johnson signed the bill establishing Medicare in 1965, he explained that it was part of Franklin D. Roosevelt’s legacy of government support for those who need it most, the elderly and the poor. At the time, there were essentially no options for older, nonworking Americans to get health coverage. Johnson signed the Medicare bill in Independence, Missouri, alongside another former president, Harry Truman, who had long advocated for universal health coverage and whose 1945 national health-care plan helped prepare the way for Medicare.
If they were alive today, these presidents would be shocked to learn that nearly half of all seniors will enroll in private, not public, Medicare plans next year. And these private plans in many ways have strayed from Medicare’s core mission of caring for the elderly while using taxpayer funds responsibly.

S22 S347 Ways to Get the Most Out of Your Elgato Stream Deck
The Elgato Stream Deck—not to be confused with Valve's Steam Deck—is an incredibly popular tool for Twitch streamers. It lets you automate basic tasks—like switching scenes and going live—but that same platform is useful even if you don't play games for an audience. I'm a huge fan of using gaming peripherals for work, so it was only a matter of time before the Stream Deck joined the productivity party.
There used to only be a few Stream Decks, which mostly varied by the number of buttons that were available. The main Stream Deck ($150) is a 15-key panel of programmable buttons that can be loaded up with actions like launching websites, entering blocks of text, and controlling features of apps like OBS Studio. Each key is also a tiny, full-color LCD display that can be customized with application icons, a library of symbols, or any other image you want.

S43 S9 S15Explained | How did Tamil cinema fare at the box-office this year?
The year 2022 has been the best ever in the last two decades or so for Tamil cinema. Two Tamil films, Mani Ratnam’s Ponniyin Selvan:1 ( PS1) and Kamal Haasan’s Vikram find a place among the top five worldwide blockbusters from Indian cinema. PS:1 has grossed Rs 495 crore and Vikram Rs 440 crore worldwide from theatricals, which is phenomenal by any yardstick. And there have been at least 20 out of the 215 odd releases (slated till Dec 31) which have been profitable for its producers from theatrical, digital and satellite rights.

S44 S42Video games in 2022: Massive mergers and peculiar portables
Gamers, and the game industry as a whole, can be a little too focused on what's next. Newly released blockbusters can fade from the public consciousness in a matter of days, while the "next generation" of console hardware or a highly anticipated, years-in-the-making sequel can dominate the headlines.

S14 S23 S26 S282022's best stories on global tech (that we wish we'd written)
There are more tech stories happening around the globe than Rest of World alone could possibly cover. Here are some of the articles, podcasts, and photography essays by other publications that most impressed us during 2022. Between them, they cover the high-profile scandals surrounding Twitter and crypto, the devastating war in Ukraine, as well as stories unfolding away from global attention, such as the experiences of low-income workers whose inputs are crucial for artificial intelligence and TikTok.
More than 80% of Brazil’s food delivery app market is taken up by iFood. This investigation, first published by the São Paulo nonprofit Agência Pública, exposed one tactic iFood uses to maintain its dominance. Digital marketing firms on the company’s payroll regularly undercut delivery workers organizing on social media by infiltrating the workers’ Facebook groups with fake profiles or by identifying leading organizers to “shadow ban” on the iFood platform. It is a striking document of how social media has become a key battleground for labor movements, and those who wish to suppress them, in the gig economy. – Andrew Deck, reporter

S45Let it snow: Scientists make metallic snowflakes out of nanoparticles
Scientists in New Zealand and Australia were conducting atomic-scale experiments with various metals dissolved in liquid solvent of gallium when they noticed something unusual: different types of metal self-assembled into different shapes of crystals—with zinc creating tiny metallic snowflakes. They described their results in a paper published earlier this month in the journal Science.

S36 S27The benefits of intermittent fasting the right way
Intermittent fasting is championed by celebrities and CEOs alike for its weight loss and health benefits. While there is promising evidence that fasting can help our bodies repair and perhaps extend our lifespans, it might not be the best approach for losing weight, and dietitians urge caution before cutting out meals.
Intermittent fasting is a type of time-restricted diet in which fasters leave a long gap between their last meal of one day and first of the next, compressing their meals into a shorter period during the day. Typically, fasters try to leave a gap of 16 hours without food and eat during an eight-hour window. Intermittent fasting is not the only type of time-restricted diet. Others like the 5:2 diet (in which dieters eat a normal amount of food for five days before two days of eating only 25% of their usual calorie intake) focus more on the amount of food consumed, rather than the time between meals.

S30Tiny Tyrannosaurs Used the Buddy System
Paleontologists know little about what giant, bone-crushing tyrannosaurs were like as babies. Hatchling fossils are rare and provide few hints about these foot-high carnivores’ behavior. But now miniature trackways, found in rock roughly 72 million years old, offer evidence that baby tyrannosaurs traveled in pairs.
Paleontologists first found the trackways during a riverbank survey of southwestern Alberta’s St. Mary River Formation. The site is rife with tracks made by many dinosaur species—“a busy time at the beach,” as Royal Tyrrell Museum of Palaeontology researcher Donald Henderson and his colleagues describe it in the Canadian Journal of Earth Sciences. Among the fossil footprints are seven miniature dinosaur trackways suggestive of individuals moving in pairs. “The form of the small tracks, as well as the pace lengths, is a good match to what could be produced by hatchling [tyrannosaurs] Albertosaurus or Gorgosaurus,” Henderson says, noting that the tracks’ pointed claw tips suggest a predator.

S37Glass beads in lunar soil reveal ancient asteroid bombardments on the Moon and Earth
In 2020, China’s Chang’e 5 mission sampled more than a kilogram of Moon rock and soil and brought it back to Earth. The samples contain countless tiny beads of glass, created when asteroids hit the Moon and splashed out droplets of molten rock around the impact site.
We have analysed these glass beads and the impact craters near where they were found in great detail. Our results, published in Science Advances, reveal new details about the history of asteroids hitting the Moon over the past 2 billion years.

S38Are humans wired for conflict? Charles Darwin vs. "Lord of the Flies"
The iconic novel Lord of the Flies paints a picture of human beings as naturally selfish and prone to conflict, but that is not the most accurate depiction of humanity, argues historian Rutger Bregman.
Bregman shares a true story from his research about a group of Tongan students who survived on an island together for 15 months in 1965, not through brutal alliances, but by working together and forming a functional community.

S24 S33The 12 Best Books of 2022
Chaos reigned this year. Russia invaded Ukraine, the US Supreme Court overturned Roe v. Wade, Will Smith slapped Chris Rock at the Oscars, Elon Musk remade Twitter in his erratic image, mass shooters continued to terrorize the United States, civil rights protests swept Iran, Queen Elizabeth died, Bolsanaro got the boot in Brazil, boards were buttered, crypto crumbled, and overall, every single week felt like the entire chorus to “We Didn’t Start the Fire.”
Perhaps because of all this tumult, turmoil, and general mayhem, I gravitated toward complicated, thorny stories this year—strange, slippery, often unsettling fictions, and nuanced, searching non-fiction. This is an idiosyncratic, deeply incomplete, and totally subjective list, the result of one person’s avid but disorganized reading schedule. But these are the novels, short stories, and non-fiction books that stood out for me in 2022. Here’s hoping it helps you find your next great read.

S31The Most Dangerous People on the Internet in 2022
Russian soldiers poured into Ukraine, accompanied by a wave of cyberattacks across the country. A major cryptocurrency exchange imploded and declared bankruptcy, vaporizing billions of dollars from that digital economy. The once-biggest dark-web drug market—after being demolished by law enforcement—clawed back to the top of the online underworld after doggedly resurrecting itself.
It's not 2014, though you could be forgiven for being confused. No, all these episodes of global chaos occurred in 2022, each one a rerun of previous events, but now with the threat they posed vastly multiplied in scale.
