My phone is an ereader now

My phone is an ereader now I got a Kobo in 2016 after borrowing my mom's old one for a year before that. It probably is responsible for getting me reading again after high school. I used to be an avid reader, the sort of kid who would have to be told to put down the book and go to sleep, and who would then creep slowly to the bookshelf to pick it up again without arousing suspicion after the light had been turned out. I think I slowed my reading for fun as the work load of school increased, and

Hurricane category 6 could be introduced under new storm severity scale

Hurricane Florence made landfall in South Carolina in September 2018. It was a Category 1 hurricane, but the devastating flooding that followed killed 55 people. A new hurricane categorization system could help people better prepare for storms by incorporating risks from storm surges and rainfall into the categories, a study published this month reveals. Storm surges — elevated seawater levels near coasts — and rainfall cause almost 80% of hurricane deaths, yet they are not accounted for in th

Bi-directional accountability: A leadership shift most organizations avoid

Most organizations enforce one-way accountability. The CBC framework flips that, making commitments mutual, visible, and enforceable. In CBC, ambiguity is a leadership failure, and credibility comes from delivering results — not titles. When things go wrong, it’s easy to point down the org chart, much harder to look up. In most organizations, accountability flows one way. Teams are held to deadlines, deliverables, and performance metrics, while leaders enjoy a looser standard — insulated by hi

Why the New York Times Claimed Life Had Been Found on Mars

If you followed news about either the media industry or space exploration back in 2021, you probably remember when the New York Times accidentally published a story claiming that watermelons had been found on the planet Mars. "Authorities say rise of fruit aliens is to blame for glut of outer space watermelons," read the story, which the newspaper deleted less than an hour later, but is still accessible in an archived snapshot. "The FBI declined to comment on reports of watermelons raining down

As Ocean Water Gets Worse, Sharks' Teeth Start to Dissolve

Sharks have been on this planet for more than 400 million years. They're older than the first trees, the North Star, and even the rings of Saturn. They've seen and been through it all — but the mounting effects of human driven climate change could be what finally proves too much for these ancient beings. As we continue to pump astronomical amounts of carbon dioxide into the atmosphere, nearly a third of it gets absorbed by the ocean, gradually making its water more acidic. For sharks, the cons

Mushroom Gummies: Expert Advice on Side Effects and Benefits

Mushrooms have been used as medicine for many years, but nowadays, you don't have to reap these wellness rewards by cooking them. The potential health benefits of functional varieties have even led people to add them to their morning cup of joe. But if you'd like to maintain the sanctity of your coffee, you can even buy them in the form of mushroom gummies. However, before you buy a bottle of mushroom gummies, you should be fully aware of the potential benefits and side effects. We consulted ex

Ride1Up TrailRush Electric Mountain Bike Review: Quality Components, Bargain Price

Buying a direct-to-consumer bike can be almost as big a gamble as investing in cryptocurrency. While a customer is not likely to lose their shirt investing in a new electric bike, buying a poorly made one may result in a serious crash or catch the garage on fire. For these reasons and more, it’s wise to do some research before clicking on the Add to Cart button. The highest-end legacy-brand e-MTBs retail for upwards of $14,000. So what do you get for $2,095, the price of Ride1Up’s first-ever el

The Grammar According to West

The Grammar According to West by Douglas B. West Summary I have been accumulating observations about writing mathematics for many years. These conclusions arose both from writing textbooks and from noting writing errors commonly made by my thesis students and in papers submitted to journals. My first objective was to train my students, thereby reducing the time needed to edit their theses. As the document grew, I made it publicly available in the hope that others may find it useful. I have r

Meta will sell you refurbished Ray-Ban smart glasses for $76 off - how to find them

Jason Hiner/ZDNET Meta Ray-Bans have often been very difficult to find in stock at both retailers and online stores for the past two years -- and they rarely go on sale. But one of the best ways to not only get a 20% discount but also find some of the styles that have been discontinued or are rarely ever in stock is to use the little-known Meta Refurbished AI Glasses online store. I recently ordered a pair of Meta Ray-Bans in the Skylar style with the Shiny Caramel finish with Polar Brown lens

iPhone’s Crash Detection feature saves teen who fell asleep behind the wheel

This is probably not the first time you’ve read about an iPhone automatically calling 911 following a serious car crash, but stories like this never cease to impress. Watch the video below. As reported by WFMJ, earlier this month, 16-year-old Lindsay Leskovac fell asleep while driving back home late at night. She crashed her truck, suffered multiple fractures, including both legs and her cervical spine, and lost consciousness. Upon detecting the crash, her iPhone automatically dialed 911, and

How to Stop Google from AI-Summarising Your Website

Google has introduced AI-generated summaries in its search results—known as AI Overviews—which often pull your content into a snippet that may generate traffic away from your site. While it seems like a "feature," these summaries force site owners into a no-win choice between giving up control or visibility—arguably a dark pattern tactic by Google. To make matters worse, while there are regulatory investigations underway in the EU and UK striving to hold Google accountable, there’s still no goo

The 10 Best Moments in ‘Jaws’

Showrunner wants to turn you into a happy little content prompter for the ‘Netflix of AI’

is a reporter focusing on film, TV, and pop culture. Before The Verge, he wrote about comic books, labor, race, and more at io9 and Gizmodo for almost five years. As one of the cofounders behind Oculus Story Studio, Edward Saatchi knows how hard it can be to sell people on new tech that bills itself as revolutionary. Even though Story Studio snagged an Emmy for one of its three animated features, a general lack of public interest in VR movies led Meta to shutter Oculus Story Studio back in 2017

SpaceX’s Next Big Trick: Catch the Starship Upper Stage With ‘Chopsticks’

SpaceX finally broke out of a serious Starship slump on Tuesday, acing the rocket’s 10th flight after months of failed attemps. Now, CEO Elon Musk has set his sights on the next big challenge: catching Starship’s upper stage with Mechazilla’s “chopstick” arms. In an X post on Wednesday, August 27, Musk said the next opportunities to attempt this feat would likely be flights 13 through 15, depending on how well V3—the next iteration of Starship—performs. The Starship launched Tuesday was a V2, w

Wearable devices are sharing your private data - these are the 5 worst offenders

Google just can’t stop reimagining how it wants Quick Share to work (APK teardown)

Rita El Khoury / Android Authority TL;DR Android Quick Share is currently in the process of rolling out a new UI, but even more changes could be in the works. Developers appear to be working on an interface that’s much more minimal, without explicit send and receive screens. It’s possible some of this work could be focused on Quick Share for larger-screen devices. When it comes to app development, does progress ever really rest? No matter how many times you retool your app with a fresh new l

Best Washing Machines for Your Home in 2025

If available features are driving your comparative shopping experience for washing machines, GE offers a top-tier, front-loading model with consistent customer satisfaction and just about every available add-on. While it is more expensive than the models listed above, it's less expensive than other models that offer as many features as it does. This washing m

Starship’s heat shield appears to have performed quite well in test

One of the more curious aspects of the 10th flight of SpaceX's Starship rocket on Tuesday was the striking orange discoloration of the second stage. This could be observed on video taken from a buoy near the landing site as the vehicle made a soft landing in the Indian Ocean. This color—so different from the silvery skin and black tiles that cover Starship's upper stage—led to all sorts of speculation. Had heating damaged the stainless steel skin? Had the vehicle's tiles been shucked off, leavi

Microsoft and Uber alum raises $3M for YC-backed Munify, a neobank for the Egyptian diaspora

Khalid Ashmawy remembers the first time he wired money home while studying in Europe. He had just received his monthly stipend as a master’s student in Stuttgart and wanted to send part of it back to his family in Cairo. It was usually a slow and expensive process, he recalled. A $400 wire transfer, for instance, could cost $40 in fees and take three business days to arrive. Years later, while working at Microsoft and Uber in the U.S., and even after founding a startup, that experience hadn’t

Get a Google Pixel 10? You need to change this display setting immediately

Joe Maring / Android Authority There’s a lot to like about the Google Pixel 10. The triple-camera system on the back is one of the most impressive we’ve seen for a non-Pro Pixel. Magnetic Qi2 charging is a fantastic addition, the Tensor G5 is a significant upgrade, and the Indigo color this year is oh-so-pretty. Google has also been at the top of its display game for a while now, and the Pixel 10 is no exception. With a 6.3-inch OLED panel, a 120Hz refresh rate, and up to 3,000 nits of peak br

The best VPN deals: Get up to 77 percent off NordVPN, ProtonVPN, Surfshark and others

A virtual private network (VPN) can save you a lot of money if you use it right. By changing your virtual location, you can use one streaming service to see shows that might be scattered between three or four in your home country. You can also trawl the world for discounts that only show up in a few select regions. And of course, you can't put a price on the joy of taking back your online business from intrusive ads and trackers. VPN providers are all competing to boost their subscriber counts,
