One Tech Tip: How to use your smartphone to photograph the Northern Lights
Space weather forecasters issued a rare, severe solar storm alert on Sunday after the sun let out a huge burst of energy called a coronal mass ejection last week. Another one headed toward Earth on Monday could produce more aurora sightings and with it, more social media posts of the majestic spectacle.
If you plan to head outside after sunset to look for the lights, and photograph them, there are things you can do to make sure you get the best shot. First, though, try to find a quiet, dark area away from light pollution and check the weather forecast — clouds can cover up the aurora borealis.
As for equipment, ideally, you should use a DSLR camera because its manual controls give you lots of control, and a tripod to hold it steady. But many people won't have this sort of equipment. But if you've only got a smartphone, you can still take great photos of the night skies.
Here are some tips on how to shoot the Northern Lights:
A good setup
Before fiddling with your phone, take a few other steps to improve your chances of getting a good shot. First, dim your screen. A bright screen can hurt your night vision and both others nearby.
Even if you don't have a tripod, it's best not to hold your phone with your hands while shooting at night because there's a good chance the picture will turn out blurry. Find something to rest your device against, like a hat, a book or even just the ground.
Of course, check the forecast because auroras are best seen in clear skies. Find a dark spot, away from city lights and look north. Also, consider going horizontal instead of vertical to capture a wider image.
Tips for the iPhone
First, turn off your phone's flash. It's usually marked by the lightning bolt symbol in the corner of the screen.
Next, use Night Mode, which is found on iPhone 11 and newer models. It usually turns on automatically in low light. You can tell it's on because a circular icon with a crescent moon will appear in the top left corner of the screen.
For night shots, a longer exposure is better because there's more time for light to hit the lens. Apple says Night Mode's exposure length is normally determined automatically, but you can still experiment with manual controls.
To get to the controls, tap the arrow at the top of the camera screen, which will bring up a row of controls at the bottom. Tap find the exposure icon, which is the same crescent moon symbol as the Night Mode icon.
A slider will come up, which you can drag left or right to choose between Auto and Max timer settings. Max will give you the longest exposure time. Whichever setting you choose, it will be remembered for the next time.
Then, tap the shutter button to take your shot. Better yet, turn on the countdown timer. The delay gives you time to move away and reduces the chance any movement from your finger will affect the shot.
If you are going handheld, and the iPhone detects movement in the frame, it will display crosshairs. Try to keep them lined up to minimize any motion that can ruin the shot.
Tips for Android devices
There are similar night and astrophotography modes available on most Android devices.
On Pixel phones, tap the Night Sight setting at the bottom of the screen. If you're using a tripod, the astrophotography setting will come up automatically once the phone has detected that it is still and ready, according to Google's online guide.
Now you can press the shutter, which will trigger a five-second countdown timer before the phone starts taking a long exposure of up to four minutes.
If you don't have a tripod, you'll have to activate the astro mode by tapping the crescent moon icon and swiping the slider.
You'll still get a five-second timer when you hit the shutter, which Google says 'allows you to place your phone down on a steady surface facing the sky.' Then the phone will play a sound to let you know it's done.
Newer Samsung phones can access an astrophoto mode, but users will have to download the company's free Expert Raw camera app to get it.
Use a third-party app
If you feel like you need some outside assistance for your snapshots, tourist boards and other outfits from some Nordic countries have suggestions for you. Iceland Air, for instance, has a blog entry on the best apps for taking pictures of the Northern lights, including the Northern Lights Photo Taker, which costs 99 cents to download and 'does exactly what it says,' according to the post.
Inspired by Iceland lists additional apps to try, especially if your default camera lacks manual controls. These include NightCap Camera, ProCamera, and Slow Shutter for iOS. For Android, ProCam X Lite is a good choice.
Visit Norway suggests similar camera replacement apps, but notes that you should test them before you go to see what works best for you and the type of phone you have.

AI gives students more reasons to not read books. It's hurting their literacy
A perfect storm is brewing for reading. AI arrived as both kids and adults were already spending less time reading books than they did in the not-so-distant past. As a linguist, I study how technology influences the ways people read, write, and think. This includes the impact of artificial intelligence, which is dramatically changing how people engage with books or other kinds of writing, whether it's assigned, used for research, or read for pleasure. I worry that AI is accelerating an ongoing shift in the value people place on reading as a human endeavor. Everything but the book AI's writing skills have gotten plenty of attention. But researchers and teachers are only now starting to talk about AI's ability to 'read' massive datasets before churning out summaries, analyses, or comparisons of books, essays, and articles. Need to read a novel for class? These days, you might get by with skimming through an AI-generated summary of the plot and key themes. This kind of possibility, which undermines people's motivation to read on their own, prompted me to write a book about the pros and cons of letting AI do the reading for you. Palming off the work of summarizing or analyzing texts is hardly new. CliffsNotes dates back to the late 1950s. Centuries earlier, the Royal Society of London began producing summaries of the scientific papers that appeared in its voluminous Philosophical Transactions journal. By the mid-20th century, abstracts had become ubiquitous in scholarly articles. Potential readers could now peruse the abstract before deciding whether to tackle the piece in its entirety. The internet opened up an array of additional reading shortcuts. For instance, Blinkist is an app-based subscription service that condenses mostly nonfiction books into roughly 15-minute summaries —ccalled 'Blinks'—that are available in both audio and text. But generative AI elevates such work-arounds to new heights. AI-driven apps like BooksAI provide the kinds of summaries and analyses that used to be crafted by humans. Meanwhile, invites you to 'chat' with books. In neither case do you need to read the books yourself. If you're a student asked to compare Mark Twain's The Adventures of Huckleberry Finn with J. D. Salinger's The Catcher in the Rye as coming-of-age novels, CliffsNotes only gets you so far. Sure, you can read summaries of each book, but you still must do the comparison yourself. With general large language models or specialized tools such as Google NotebookLM, AI handles both the 'reading' and the comparing, even generating smart questions to pose in class. The downside is that you lose out on a critical benefit of reading a coming-of-age novel: the personal growth that comes from vicariously experiencing the protagonist's struggles. In the world of academic research, AI offerings like SciSpace, Elicit, and Consensus combine the power of search engines and large language models. They locate relevant articles and then summarize and synthesize them, slashing the hours needed to conduct literature reviews. On its website, Elsevier's ScienceDirect AI gloats: 'Goodbye wasted reading time. Hello relevance.' Maybe. Excluded from the process is judging for yourself what counts as relevant and making your own connections between ideas. Reader unfriendly? Even before generative AI went mainstream, fewer people were reading books, whether for pleasure or for class. In the U.S., the National Assessment of Educational Progress reported that the number of fourth graders who read for fun almost every day slipped from 53% in 1984 to 39% in 2022. For eighth graders? From 35% in 1984 to 14% in 2023. The U.K.'s 2024 National Literacy Trust survey revealed that only one in three 8- to 18-year-olds said they enjoyed reading in their spare time, a drop of almost 9 percentage points from just the previous year. Similar trends exist among older students. In a 2018 survey of 600,000 15-year-olds across 79 countries, 49% reported reading only when they had to. That's up from 36% about a decade earlier. The picture for college students is no brighter. A spate of recent articles has chronicled how little reading is happening in American higher education. My work with literacy researcher Anne Mangen found that faculty are reducing the amount of reading they assign, often in response to students refusing to do it. Emblematic of the problem is a troubling observation from cultural commentator David Brooks: 'I once asked a group of students on their final day at their prestigious university what book had changed their life over the previous four years. A long, awkward silence followed. Finally a student said: 'You have to understand, we don't read like that. We only sample enough of each book to get through the class.'' Now adults: According to YouGov, just 54% of Americans read at least one book in 2023. The situation in South Korea is even bleaker, where only 43% of adults said they had read at least one book in 2023, down from almost 87% in 1994. In the U.K., the Reading Agency observed declines in adult reading and hinted at one reason why. In 2024, 35% of adults identified as lapsed readers—they once read regularly, but no longer do. Of those lapsed readers, 26% indicated they had stopped reading because of time spent on social media. The phrase lapsed reader might now apply to anyone who deprioritizes reading, whether it's due to lack of interest, devoting more time to social media, or letting AI do the reading for them. All that's lost, missed, and forgotten Why read in the first place? The justifications are endless, as are the streams of books and websites making the case. There's reading for pleasure, stress reduction, learning, and personal development. You can find correlations between reading and brain growth in children, happiness, longevity, and slowing cognitive decline. This last issue is particularly relevant as people increasingly let AI do cognitive work on their behalf, a process known as cognitive offloading. Research has emerged showing the extent to which people are engaging in cognitive offloading when they use AI. The evidence reveals that the more users rely on AI to perform work for them, the less they see themselves as drawing upon their own thinking capacities. A study employing EEG measurements found different brain connectivity patterns when participants enlisted AI to help them write an essay than when writing it on their own. It's too soon to know what effects AI might have on our long-term ability to think for ourselves. What's more, the research so far has largely focused on writing tasks or general use of AI tools, not on reading. But if we lose practice in reading and analyzing and formulating our own interpretations, those skills are at risk of weakening. Cognitive skills aren't the only thing at stake when we rely too heavily on AI to do our reading work for us. We also miss out on so much of what makes reading enjoyable—encountering a moving piece of dialogue, relishing a turn of phrase, connecting with a character. AI's lure of efficiency is tantalizing. But it risks undermining the benefits of literacy.

Why Noise Pollution Is Slowly Killing Us All
Given the growing cacophony of noise pollution here on planet Earth, maybe it's a good thing that in space no one can hear you scream, as the 'Alien' film franchise so aptly points out. It's not just undersea noise negatively affecting our planet's marine life. Noise is also affecting terrestrial wildlife reserves and natural parks. And on a day-to-day basis, human-generated noise is literally endangering both the mental and physical health of a large swath of the global population. It's a point repeatedly made clear in 'Clamor: How Noise Took Over The World And How We Can Take It Back,' by science journalist Chris Berdik. The author provides us with a comprehensive and well-crafted narrative of the history of noise pollution as well as what hope we have in countering this threat. As anyone who's experienced the din of a busy airport, freeway or even Manhattan at rush hour can attest, noise linked to transportation can be overwhelming. In fact, a 2020 report by the European Environment Agency linked noise from transportation and other sources to some 48,000 new cases of heart disease and 12,000 premature deaths across the European continent every year, Berdik writes. As For The U.S.? According to the American Public Health Association, noise could be putting the health of more than 100 million Americans at risk, Berdik writes. And there's little escape at the office. Open concept office designs have only made the problem worse. By 2017, at least 70 percent of American offices were open plan in design despite mounting evidence that the racket it produced drove employees crazy and hampered their job performance, writes Berdik. But regardless of office type, thousands of workers have found links between self-reported workplace noise and more days spent sick at home, Berdik notes. Noise pollution also negatively affects wildlife. As Berdik points out, biologists at California Polytechnic State University spent several years studying the effects of noise on the flora and fauna of Rattlesnake Canyon in northwest New Mexico which hosts a plethora of natural gas wells, Berdik writes. The researchers found that the natural gas wells that also had noisy compression stations drove away two bird species, the Woodhouse Scrub Jay and Mountain Bluebirds, Berdik notes. Both species are key seed distributors for the canyon's primary tree species — the Pinyon Pine and the Utah Juniper, Berdik notes. Unnecessary Noise And all too often, we generate insane amounts of noise for no good reason. As I can personally attest, in the mid-1980s Manhattan restauranteurs started thinking diners would prefer to eat in restaurants that offered all the acoustics of a busy industrial warehouse. Open kitchens, high ceilings and cement floors wreaked havoc on decibel levels. But it was a pattern that was repeated nationwide and still pervades most urban restaurants. Urban cafes are also some of the worst offenders. In addition to the noise their machines make while whipping up lattes and frappuccinos, their usual floor design is such that the acoustics are horrific. In addition, there's the constant drone of music at ridiculously high levels. That's strange, since most people are usually there to work on their laptops or check their phones in relative tranquility. Sadly, public libraries are no longer refuges of quiet as they are now functioning as de facto community centers. In the U.S., at least, people who want to work in peace and relative quiet must pay for that privilege at woefully overpriced co-working establishments. Soundscape Design Despite Berdik's plea for soundscapes designed for public spaces, I say why introduce more sound when less sound would do? Let me remind you of the healing powers of silence. There's nothing like pulling a vehicle over to the side of a two-lane blacktop and stepping out into the complete silence of a desert landscape. And anyone who's had the privilege of skiing in an empty high mountain pass can also attest to the peaceful crunch of snow beneath one's feet. Can natural sounds counter noise pollution? It's a point that Berdik makes repeatedly in his book. As he notes, a 2022 study by environmental neuroscientists at Berlin's Max Planck Institute found that only six minutes of recorded birdsong reduced measures of depression and anxiety in listeners. In contrast, people subjected to recorded traffic noise came to feel more depressed, writes Berdik. There has been a myriad of noise mitigation strategies put forth over the last few decades. But I'm not as sanguine as Berdik about ways to win the war on noise pollution. It's both insidious and a blatant threat to our collective sanity. But what's perhaps most distressing about this problem is that it's woefully underappreciated and in comparison to other pressing environmental issues rarely gets much attention. Yet in his book, Berdkik reminds us of what's at stake. The Bottom Line? 'Clamor' is an important work that deserves to be read and used as a springboard for serious discourse about this burgeoning problem that cuts across almost every aspect of global society. Quiet is indeed vital, and it's disappearing; sonic tranquility is fast becoming a luxury product for those who can afford it, Berdik writes.
