brandish

Merriam-Webster's Word of the Day for September 24, 2025 is:

brandish • \BRAN-dish\  • verb

To brandish something, such as a weapon, is to wave or swing it in a threatening or excited manner.

// Squeals of laughter erupted as three children brandishing squirt guns rounded the corner of the house.

See the entry >

Examples:

“The dancers are young men from the neighborhoods dressed in dark robes accented by bright yellow, red and blue accessories and tall, maroon hats called Tkoumbout adorned with silver jewelry. The men’s dances and women’s chants have been passed down through generations. Children participate in the festivities by mimicking the older performers. Boys brandish miniature swords and scarves in their small hands and girls stand with the female drummers.” — Audrey Thibert, The Associated Press, 1 July 2025

Did you know?

The word brandish is often paired with a word for a weapon, such as knife or handgun. The link between brandish and weaponry is present in the word’s etymology: brandish comes ultimately from a Germanic word meaning “sword.” Since the word’s 14th century introduction to the English language (by way of Anglo-French) weapons have commonly been the things brandished, but also extensive is the use of brandish with things that are wielded to defeat in other ways, such as banners and placards used in the war of ideas. One can even brandish something that isn’t physical, such as a law or one’s intellect. In that case, you are figuratively waving the thing in someone’s face so that it cannot be ignored.

This Is the ‘Right’ Temperature for Turning on Your Heat This Fall

Posted by Beth Skwarecki

As fall creeps toward winter, we know we’ll have to turn on the heat. But when is the right time? If you’re arguing with your partner or roommate about the thermostat, we’re happy to be able to end that argument for you. (They’ll probably never admit they’re wrong, though.)

The easiest answer, which is not necessarily the correct answer, is to look for nighttime lows falling below 55 degrees Fahrenheit. That said, neither the calendar nor the weather forecast can give you very good advice here. The temperature inside your house is what matters. If your house occupies a sunny spot in a warm climate, you may be able to delay turning on your heat until it’s nearly the dead of winter. On the other hand, if your house is poorly insulated, sits in a shady area, or your local climate is on the chilly side, you may need to turn it on sooner.

So while you can ask your neighbors what date or what outdoor temperature they usually use as their guideline, you’ll need to look at your own thermostat to know when it’s time.

Keep the indoor temperature above 64 degrees for your health

A report from the World Health Organization points out that temperatures below 18 degrees Celsius (about 64 Fahrenheit) may cause issues for smokers, people with asthma, and people with cardiovascular disease. Warmer temperatures are associated with better lung function and better blood pressure in these people. They conclude that 64 is a good minimum for most of us, but that people with these conditions—and people who are 65 or older—should be especially sure to keep their house at 64 degrees or warmer.

That said, if you’re under 65 years old and don’t have lung or heart conditions, the WHO is fine with you putting on a sweater and dealing with it. They say lower temperatures aren’t a health risk for healthy people who are moving around enough to generate plenty of body heat. You can also safely use clothing, bedding, or heating devices to stay warm at those lower temperatures—say, snuggling up in flannel pajamas with a hot water bottle under a warm duvet.

Set your programmable thermostat to turn on the heat when the temperature drops

So that’s the general rule, but what if you have a thermostat that lets you program different temperatures for different times of day?

Energy Star suggests setting your thermostat to kick on the heat when the temperature drops to 70 degrees in the morning or evening. If you have a programmable thermostat, you can set a “setback” to allow the house to cool down a bit at night and when you’re not home.

An eight-degree setback is recommended for when you’re out of the house during the day (at the office, for example) and then again for nighttime, since cool temperatures help us sleep, and we can use blankets if we’re too cold. That eight-degree setback would give us an indoor temperature that could fall as low as 62 degrees. Try that and see how the house feels. If it’s too cold, consider bumping up to at least 64.

If you want to wait as long as possible, at least do a test run

No matter what I say here, I know that some of you will want to wait as long as possible to turn on the heat for the first time. Just do yourself a favor: Turn on the heat at some point in the early fall just to make sure everything is working OK. When it finally gets too cold to go without the heat, you don't want that day to be the day you learn something isn't working properly.

Walmart has jumped on the October Prime Day bandwagon in an attempt to sway you away from the biggest online sale of the fall. The main event is Amazon's two-day Prime Big Deal Days promotion, aka October Prime Day. This week, Walmart officially announced its own "Prime Day"-esque promotion, and there's some good news for those of you who balk at the idea of paying for a membership to take advantage of a sale—it's free to everyone.

What is Walmart Deals?

Walmart Deals is meant to be the answer to Amazon's Prime Day sales. It is both an in-store and online sale with deals on most things that Walmart sells (food being arguably the biggest omission). The sale happens every year around spring, summer, fall, and winter, revolving around Prime Day sales.

When does Walmart Deals start?

Walmart Deals kicks off Oct. 6 at 7 p.m. ET for Walmart+ members (a five-hour head start) and Oct. 7 for everyone else. It runs until Oct. 12, both online and in stores at local opening times.

Do you need to be a Walmart+ member to shop during Walmart Deals?

No. But, if you are a Walmart+ member, you'll get early access to the sales beginning Oct. 6 at 7 p.m. ET, the evening before the event opens to the public. You can sign up for a free 30-day Walmart+ subscription or get the annual plan for $98 ($8.17/month).

What you can expect from Walmart Deals

Walmart says its sale will include many different categories, including deals on electronics, home, toys, travel, and many other categories—similar to the deals we found last year. The sale will be on Walmart.com, the Walmart app, and in stores. You can already see the landing page, even though the sale hasn't started. Here are some deals Walmart says will be available:

Electronics

Home

Seasonal Decor

Toys

Fashion

 Beauty

Food

You can choose between in-store pickup and different delivery options, including early-morning delivery, late-night express delivery, and next- and two-day shipping.

All of the other competing sales for October Prime Day

You can always expect major retailers to have their own competitive sales, the big ones being Best Buy, Target, and, of course, Amazon. Target has been the only other retailer to officially announce their October competition sale. Like in previous years, the dates for these sales will start earlier, overlap, and run longer than October Prime Day. There are usually a couple of deals that are better than Amazon's Prime Day from each of the retailers, but the majority of the good deals will be on Amazon. I will be updating this post with details on those offerings as soon as they've been announced.

What You Should Actually Know About Tylenol and Pregnancy

Posted by Beth Skwarecki

Did you know you can customize Google to filter out garbage? Take these steps for better search results, including adding my work at Lifehacker as a preferred source.


In a press conference totally divorced from reality as scientists and doctors understand it, President Trump announced yesterday that the FDA would be warning providers and patients away from acetaminophen (such as Tylenol) in pregnancy. There were some other unsubstantiated claims about vaccines and autism mixed in, so let me break down what’s actually known and understood here. 

What is acetaminophen? 

Acetaminophen is an over-the-counter medication used to relieve pain and fevers. The flagship products of the Tylenol company are acetaminophen pills and syrups, but Tylenol sells other products as well, including medicines with a mixture of active ingredients. (Always check the Drug Facts label when you take medications to know what you’re getting.) I’ll often use the word Tylenol, since it’s more commonly known, but acetaminophen is also available in other products, like Excedrin and NyQuil..

Outside the U.S., acetaminophen is often known as paracetamol: Same drug, different generic name, though Trump seems to have stuck with the brand name Tylenol during the press conference. The Tylenol company now has a pop-up on its website pointing customers to this response, which correctly points out there is no credible link between Tylenol and autism.

What the science actually says about acetaminophen and autism 

The short answer: There is no credible link between autism and the use of acetaminophen in pregnancy. But HHS Secretary Robert F. Kennedy, Jr. sorta-kinda spoke correctly when, during the press conference, he said there were some studies that “suggest a potential” connection between acetaminophen and autism. For example, a review published this year (not a study itself, but an analysis of prior studies) found that some studies do in fact show a link between acetaminophen use in pregnancy and autism, although the evidence is mixed. 

A press release about the review noted, “While the study does not show that acetaminophen directly causes neurodevelopmental disorders [emphasis mine], the research team’s findings strengthen the evidence for a connection and raise concerns about current clinical practices.” That said, it seems most medical experts aren’t convinced that this review, or the studies that claimed to find a link, are strong enough to change clinical practice. (More in the next section on what medical experts are saying about these claims.) 

So why doesn’t this count as strong evidence? An association (two things tend to occur together) is not the same as causality (this thing definitively causes that thing). People who take acetaminophen during pregnancy tend to be different than those who don’t—for example, if somebody takes Tylenol during pregnancy because they are sick, it may be the sickness rather than the Tylenol that is the risk factor. Or the people who take Tylenol may be different from people who don’t in some other way.

A large study published last year took this into account. The researchers looked at 2.5 million children in Sweden, and their initial analysis found an increase in risk of autism in children whose mothers had taken acetaminophen. But then they looked at whether this relationship held up between pairs of siblings, where one was exposed to acetaminophen in utero and the other was not. And the relationship disappeared. 

In other words, if acetaminophen increased autism risk, you’d expect the sibling exposed to the drug in utero to have a higher likelihood of autism than their sibling who wasn’t. But that wasn’t the case. Instead, it seems some families have a higher likelihood than others of having children with autism, and taking acetaminophen doesn’t increase the risk within that family. 

What medical experts say about acetaminophen in pregnancy

Acetaminophen (including Tylenol) is generally considered the safest pain reliever for use in pregnancy. Other common alternatives, like ibuprofen, have known risks and are not recommended if you are able to take acetaminophen instead. Medical experts also agree that it’s dangerous to leave pain and fever untreated during pregnancy. 

Several medical organizations issued statements in response to the president’s press conference, all of which are worth reading in full, but here are some key quotes from each: 

The American College of Obstetricians and Gynecologists said in a statement: “Suggestions that acetaminophen use in pregnancy causes autism are not only highly concerning to clinicians but also irresponsible when considering the harmful and confusing message they send to pregnant patients, including those who may need to rely on this beneficial medicine during pregnancy.” The statement goes on to discuss the strength of the evidence, saying that “not a single reputable study has successfully concluded that the use of acetaminophen in any trimester of pregnancy causes neurodevelopmental disorders in children.”

The Society for Maternal-Fetal Medicine said in their statement: “In response to today’s White House press conference announcement, the Society for Maternal-Fetal Medicine (SMFM) reiterates its recommendation advising both physicians and patients that acetaminophen is an appropriate medication to treat pain and fever during pregnancy.  Despite assertions to the contrary, a thorough review of existing research suggesting a potential link between acetaminophen use during pregnancy and an increased risk of autism and attention deficit and hyperactivity disorder (ADHD) in children has not established a causal relationship.”

The American Academy of Pediatrics said in their statement: “Today’s White House event on autism was filled with dangerous claims and misleading information that sends a confusing message to parents and expecting parents and does a disservice to autistic individuals. … Families who have questions about their child’s medications, autism care plans or other health care should consult with their pediatrician or health care provider.”

The Autism Science Foundation said in their statement: “Any association between acetaminophen and autism is based on limited, conflicting, and inconsistent science and is premature… Today’s announcement distracts from the urgent scientific work needed to understand the true causes of autism and to develop better supports and interventions for autistic people and their families.”

The European Medicines Agency, which plays a similar role in Europe as the FDA does in the U.S., issued a statement that there is no new evidence that would require reevaluating the status or labeling for acetaminophen, which they call paracetamol. “Paracetamol remains an important option to treat pain or fever in pregnant women. Our advice is based on a rigorous assessment of the available scientific data and we have found no evidence that taking paracetamol during pregnancy causes autism in children.”

There is no evidence that vaccines cause autism, either

The press conference also repeated long-debunked myths about vaccines and autism. There’s no credible link here, either to vaccines in general, to specific vaccine ingredients like mercury, or to combined vaccines like the MMR (measles-mumps-rubella vaccine). 

And I shouldn’t have to tell any parent this, but babies are not in fact “pumped” with a “vat” of “80 different vaccines” at “one visit,” as Trump claimed. Babies see the pediatrician every few months during their first year of life, getting a few shots each time, many of which are combination vaccines (not just the MMR). Many of these vaccines need to be given in multiple doses—it’s not a one-and-done shot for each one. 

So it’s not true that separating the MMR into its components has “no downside.” Splitting the shots means kids are getting more needle sticks and delaying the date at which they’ll get their last dose of each and be fully protected. (The CDC’s vaccine advisory panel, which was gutted of its longtime experts and filled with controversial replacements handpicked by the HHS secretary, who has long been an anti-vaccine activist himself, has already voted to remove the combined MMR-chickenpox vaccine as a standard option for young children.) 

Trump also repeated the myth that there’s no reason for babies to get hepatitis B shots at birth. Hepatitis B can be sexually transmitted, sure, but it’s not only sexually transmitted. Babies can get it at birth from a parent who doesn’t know they have it; they can also get it during childhood from various non-sexual, non-drug exposures. Hepatitis B is a more severe disease the younger you get it, and it’s one of the vaccines babies’ immune systems can process even in those early days (not all vaccines will work that early) so the risk-benefit calculation is an easy one: this vaccine, like others, offers children real protection.

I Added the Fitbod Strength-Training App to My Cardio Routine, and I Love It

Posted by Meredith Dietz

Did you know you can customize Google to filter out garbage? Take these steps for better search results, including adding my work at Lifehacker as a preferred source.


When I first reviewed Fitbod (which you can read here), I approached it with the skepticism of someone whose idea of strength training was lifting my water bottle during long runs. Well, that's an exaggeration, but there's some truth in my inability to squeeze proper strength training into my schedule. The big promise of Fitbod is that your strength program is AI-powered to be perfect for you personally. For me, that means a strength program that works around my limited free time and already fatigued muscles.

Like many endurance athletes, I usually fall into the trap of "not having time" for anything but running. My weekly routine has easy runs, tempo runs, long runs, and maybe some yoga if I'm feeling fancy. And when minor injuries started creeping in—IT band tightness here, some knee discomfort there—I just take a few days off and get back to pounding the pavement.

The truth is, I can be pretty afraid of strength training. Not just afraid of looking foolish in the gym (though that's part of it), but genuinely convinced that building muscle would slow me down. Wouldn't all that extra weight just make running harder?

Fast forward a few months, and I'm writing this after completing a deadlift set that would have terrified past-me. Here's how Fitbod transformed my relationship with strength training and, unsurprisingly, made me a better distance runner.

How Fitbod works with a running-focused schedule

What drew me to Fitbod initially was its promise of efficient, customized workouts. As someone juggling 30+ mile weeks with a full-time job, I didn't have hours to spend in the gym figuring out what exercises to do or how many sets and reps were optimal.

Fitbod's interface impressed me from day one. After inputting my goals (I selected "gain muscle"), available equipment, and time constraints, it generated 30-45 minute workouts that felt manageable alongside my running schedule.

Another major factor to understand about Fitbod's programming is its "non-linear" approach. A ton of beginner strength programs go by linear progression. This means you add small, consistent increments of weight to a given lift each workout or week, keeping the exercises, sets, and reps the same. Fitbod doesn’t go by this linear "add 5 pounds every session" approach of traditional programs. The whole AI-powered promise here is that Fitbod pushes you to increase weights when it deems you ready, not according to an arbitrary schedule. So, during my peak mileage weeks, either Fitbod automatically adjusted to lighter loads and fewer sets, or I could easily adjust this manually. Then, in recovery weeks, Fitbod's program knew to ramp up the intensity. This intelligent programming meant I wasn't trying to PR my squat the day before a 22-mile long run.

What I like about Fitbod's approach

After a few weeks of testing, I can report that Fitbod really doesn't just throw random exercises at you. And if you say you're a runner, then tts selections make sense for runners—lots of single-leg work, core stability, and posterior chain strengthening. That posterior chain strengthening that Fitbod prioritized (deadlifts, hip thrusts, rows) is so, so important to complement all the forward-focused motion of running. The app's algorithm seemed to understand that I needed functional strength, not just bigger muscles.

On its website, Fitbod explains its algorithm and how the app generates workouts, but simply put, it starts by analyzing multiple factors: previous workout data, muscle recovery status, available time, and your feedback on individual exercises. As you keep using the app, it analyzes your logged data, calculates muscle recovery, measures training volume for progressive overload, adjusts for your specific goals (hypertrophy vs. strength), applies intelligent variation to prevent plateaus, and generates your next customized workout. This process repeats with every session, allegedly making your program increasingly personalized over time.

Going into this, most important for me were two factors: Schedule flexibility and education. For the latter, the built-in video demonstrations and form cues are solid as can be. They helped me feel confident with movements I'd always avoided. (Shamefully, this includes deadlifts. I'm terrified of injuring myself during marathon season!)

For schedule flexibility: Some days I only had 20 minutes, other days I could spare 45. Fitbod easily adapts without making me feel like I was shortchanging my workout. Of course, integrating Fitbod into marathon training required some strategic planning. I timed strength sessions on easy run days or rest days, never the day before hard running workouts or long runs. Personally, I found Fitbod's workout intensity aligned perfectly with this approach.

Plus, Fitbod is a highly visual app, and that can give it a serious edge over pen-and-paper tracking. Like with Strava or Nike Run Club, the app's visual progress tracking turned strength training into a game I actually wanted to win. Hey, I'm a simple man.

The bottom line

If you're reading this as someone who lives and breathes cardio, but has been strength-training-curious, here's my advice: start small, be consistent, and trust the process. Fitbod makes this leap less intimidating by handling all the programming complexity while you focus on just showing up and doing the work. As a runner, I always view my body through the lens of performance—how fast, how far, how efficient. I think strength training introduces a different kind of body awareness focused on power, stability, and resilience.

Still: The proof needs to be in the pudding. That's the saying, right? I'll report back with my upcoming marathon time to see if Fitbod's strength program ends up having a tangible impact on my time.

TCL makes good non-OLED TVs (arguably some of the best when compared to the cost), as is the case with last year's QM7 that I got my hands on, which is still a bargain in 2025. There are plenty of differences between QLEDs and OLEDs, but unless you're planning on dropping thousands of dollars, a QLED will do just fine.

Five of the Best Ways to Study (but Not Cheat) Using AI

Posted by Lindsey Ellefson

Did you know you can customize Google to filter out garbage? Take these steps for better search results, including adding Lifehacker as a preferred source for tech news.

In the years since the launch of ChatGPT, AI tools have developed a bad reputation in the academic world for how easy they make it for students to cheat, passing off the work of a large language model as their own. Even if an LLM can produce writing for you that doesn't come off as unnatural and riddled with hallucinations, you'll be shortchanging yourself, because you won't actually absorb any of the material.

But that's not to say these tools serve no purpose in the academic world. If used correctly, they can actually help you study more efficiently. Here are five ways you can use AI in your schoolwork without cheating—or cheating yourself.

Use ChatGPT to discuss concepts

One study technique I've previously recommended is simply having a conversation with another person who doesn’t know anything about the topic you’re studying, to identify areas where your own understanding is lacking. It's a great option because it helps you make connections between concepts as you're working out how to explain them to someone else, and it boosts your confidence in the subject matter when you are able to present it as the expert. But you might not always have someone around to serve as the uninformed rube in your roleplaying, which is when ChatGPT can help you out.

When I was in grad school, I asked ChatGPT to allow me to "teach" it about a topic I was studying—community-based health interventions—and we “discussed” different levels of community engagement. ChatGPT actually had interesting questions that helped me think of creative solutions I could investigate in the course of my work.

As the American Psychological Association notes, going back and forth with the language model like this not only helps you think critically and creatively, it also helps you practice managing technology in our changing world—a win-win.

Use AI to summarize articles

If you have to read a ton of articles or reports, try getting an AI tool to summarize them for you. This is great when you need to compare similarities or differences between pieces of research or get top-line bullet points to help you round out a paper. I fed ChatGPT an old article and asked for a summary and the language model took about 30 seconds to condense 61 pages into one key paragraph, highlighting the study design, the study goals, its findings, and its recommendations. This gave me a good idea of whether it was worth further study.

If you've only got a few documents to read, it's still best to do it yourself, but this trick that can come in handy if you've got a large number of them you're looking to sort through quickly. Just make sure you double-check the summary against the source document before you take anything in it as gospel.

My favorite tool for doing this is Google's NotebookLM. Despite my broader hesitancy about AI, I use this free software frequently because I find it's more like a personal assistant than a source of knowledge. It is similar to ChatGPT and other language models in that you can ask it questions via text-entry box, but dissimilar in that it only pulls answers from resources you've provided it. You upload PDFs, links, YouTube videos, and whatever else you want to serve as source material, then NotebookLM helps you sort through that material.

When you're using ChatGPT, it pulls answers from the entire internet, and can make serious mistakes as a result. With NotebookLM, anything it generates includes a citation you can click that reveals the exact spot it pulled the info from in your cache of resources. Instead of doing the work for you, this tool just helps you make sense of and organize all your materials.

Use ChatGPT to streamline your notes

If your notes are difficult to read or sort through, ChatGPT can help. In grad school, I assigned each of my classes a Google Doc and took notes in it all semester, but inevitably, each document eventually got disorganized, chaotic, and nearly impossible to navigate. As a test, I put my entire semester’s worth of notes for Research Methods into ChatGPT and asked it to pull out the most important information. Not only did it extract the nine steps of research planning and implementation and the principals of the Belmont Report (which were major parts of the midterm), but it reminded me how much of my grade was determined by each test, a fact I had apparently jotted down somewhere in that mess of words. It particularly emphasized things I had written down multiple times, creating a perfect study guide.

Use AI to create flashcards and quiz yourself

Flashcards and practice quizzes are excellent ways to study because they force you to use active recall to pull information from your memory. Making these materials yourself is smart, because even by sorting through your notes and writing down your practice questions, you're studying. But I'll be the first to admit that when I'm in charge of making my own quiz, I tend to go a little easy on myself. (When I'm both the student and the teacher, I somehow always get an A+. Funny how that works.) It's better to outsource the creation of these materials to an unbiased third party, and here's another area where AI can be helpful.

You can ask ChatGPT to make flashcards and quizzes, but its interface isn't really designed for that, so what it will spit back is an outline of what your flashcards should include based on the notes or resources you upload. From there, you can make the cards yourself, and get to studying (I recommend drilling flashcards using the Leitner system, which is better for helping you retain information over the long-term). You can also ask ChatGPT to quiz you, but you have to be specific with your instructions: Ask ChatGPT to quiz you one question at a time, and to not move on to a new question until you've answered the previous one correctly.

But again, here's where I recommend NotebookLM. It has built-in flashcard and quiz features that are much more interactive and easy to use. You can click a button to generate a multiple-choice quiz or flashcard deck based on the materials you uploaded. The quizzes and cards it creates are clickable, like a quiz you would take in an online class, and are based only on what you upload.

Use AI to outline essays and suggest sources

You definitely don't want ChatGPT or similar language models to "write" your whole essay—more than cheating yourself out of the learning experience, consider the fact that your teacher may run your assignment through a tool like ZeroGPT to get a report on how much of it was likely written by AI, which probably won't do wonders for your grade.

Instead, you can use AI tools to help you plan and organize your essays. I've already assembled a list of the best AI essay-helping tools, but here's the gist: You can ask ChatGPT to help you brainstorm a topic or create an essay outline. You can also ask for suggestions for sources you can then research and add into your work that you wouldn't have considered otherwise.

Two notes of caution: ChatGPT is sometimes known to make up citations, inventing a convincing article title and attributing it to a well-known source. This is why you don't want to rely on it to fully do the work for you, whether writing or research—just use it to source suggestions that you can hunt down and evaluate on your own. It won't take long to realize a source you've been given just doesn't exist.

Likewise, when ChatGPT gives you a link to a source, it adds a little code at the end of the URL that says "/?utm_source=chatgpt.com." Even if you're being as ethical as possible and clicking every link to read the material fully and consider its merits, it's a very bad look to have a bibliography full of links that make it clear you used ChatGPT for your research—a reader might even assume you had the AI write everything for you. So before turning in work, I recommend searching your documents for mentions of "chatgpt," and deleting that sneaky bit of code from any URL where you find it. Snip out everything from the question mark onward and link will still work, but won't make you look like you're doing something untoward.
