Nano-Hydroxyapatite Toothpaste: The Benefits and Risks of the Fluoride-Free Alternative

As health concerns around fluoride in public drinking water continue to swirl, nano-hydroxyapatite toothpastes are becoming increasingly popular substitutes for fluoride toothpaste. Popular brands include Boka Davids and NOBS (No Bad Stuff), which are touted as fluoride-free alternatives that whiten teeth, repair enamel and prevent cavities. "As ingredient labels shift toward cleaner, fluoride-free formulas, one compound is taking center stage in modern oral care: nano-hydroxyapatite," Dr. Pia

Table of Contents Lucid Air EVs Unlock Tesla Supercharger Access and Updates for 2026 Model Year The Lucid Air electric sedan, often named one of the fiercest competitors to Tesla's Model S, is finally gaining charging network parity.

The news comes bundled with a host of quality of life upgrades to the Air E

NetZeroNitrogen wants bacteria to replace synthetic fertilizer on farm fields

Synthetic fertilizer is a modern wonder, helping to feed billions of people, but it’s not without its costs. Fertilizer runoff from farm fields has led to dead zones in oceans around the world, where low oxygen levels have starved normally teeming coastal waters of life itself. Eliminating synthetic fertilizers is a tall order, but one startup thinks that its bacteria can eliminate up to half of it, all while undercutting fertilizer on cost. NetZeroNitrogen has developed a suite of bacterial s

Microsoft servers hacked by Chinese groups, says tech giant

Microsoft servers hacked by Chinese groups, says tech giant "Investigations into other actors also using these exploits are still ongoing," Microsoft said in a statement. The US tech giant has released security updates in response and has advised all on-premises SharePoint server customers to install them. China state-backed Linen Typhoon and Violet Typhoon as well as China-based Storm-2603 were said to have "exploited vulnerabilities" in on-premises SharePoint servers, the kind used by firms

When Is WebAssembly Going to Get DOM Support?

July 2, 2025 Volume 23, issue 3 PDF When Is WebAssembly Going to Get DOM Support? Or, how I learned to stop worrying and love glue code Daniel Ehrenberg Is WebAssembly (Wasm) really ready for production usage in web applications, even though that usage requires integration with a web page and the APIs used to manipulate it, such as the DOM? Simultaneously, the answer to this question is that "Wasm might never get direct DOM access," and "Yes, Wasm is ready for all kinds of web-integrated

Gupshup raises $60M in equity and debt, leaves unicorn status hanging

Gupshup, a business messaging startup that began its journey in India over two decades ago and became a unicorn four years ago, has raised a new over $60 million round — but is keeping its new valuation under wraps. In 2021, Gupshup raised two funding rounds within four months, securing $340 million from prominent investors including Tiger Global, Fidelity Management, Think Investments, and Malabar Investments. These rounds — the startup’s first in roughly a decade — valued Gupshup at $1.4 bill

Wild Video Shows Robot Changing Its Own Battery

What do they even need us for anymore? Self Swap As we continue on our path towards a potential future filled with tireless humanoid robots staffing factory floors, companies are looking to solve a major pain point of the tech: a limited battery life. Chinese company UBTECH recently showed off its bipedal Walker S2 robot contorting its arms to hot swap one of its battery packs — a "world's first," seemingly — which means the 95-pound automaton could technically work 24 hours a day, an integra

TapTrap: Animation‑Driven Tapjacking on Android

TapTrap is a new type of attack targeting Android devices. It allows an app without any permissions to misuse screen animations. This app can secretly open another screen, such as a permission prompt, and make it invisible. The attack can then be used to trick you into performing sensitive actions, such as granting camera permissions or even erasing your device, without your consent. The idea is simple: imagine you’re using an app. While you use it, it opens another screen, such as a system pro

The Best Places to Get Low-Cost Eye Exams, Glasses and Contacts Without Vision Insurance

Vision is our most important sense, which makes taking care of it essential. 93 million American adults are at high risk for serious vision loss, but only half of them have visited an eye doctor's office in the last 12 months, according to the CDC. This makes more sense once you consider a 2022 study that found 63% of Americans don't have vision insurance, as an eye exam, glasses and contact lenses can add up without it. If you don't have one either and are wondering if paying out of pocket for

Conspiracy theorists don’t realize they’re on the fringe

It's not that believers in conspiracy theories are massively overconfident; there is no data on that, because the studies didn't set out to quantify the degree of overconfidence, per Pennycook. Rather, "They're overconfident, and they massively overestimate how much people agree with them," he said. Ars spoke with Pennycook to learn more. Ars Technica: Why did you decide to investigate overconfidence as a contributing factor to believing conspiracies? Gordon Pennycook: There's a popular sense

Toy company may regret coming for “Sylvanian Drama” TikToker, experts say

A popular account on TikTok and Instagram stopped posting suddenly at the end of last year, hit by a lawsuit after garnering millions of views on funny videos using adorable Calico Critter dolls made for preschoolers to act out dark, cringe-y adult storylines. While millions of followers mourn the so-called "Sylvanian Drama" account's demise, experts told Ars that the creator may have a decent chance at beating the lawsuit. The "Sylvanian Drama" account derived its name from "Sylvanian Familie

More than you wanted to know about how Game Boy cartridges work

More than you wanted to know about how Game Boy cartridges work By Allison Parrish I set out a while ago to make a Game Boy cartridge from scratch. This is not a novel goal; bootleg Game Boy cartridges have existed almost as long as the Game Boy itself has, and there are many third-party cartridges now available for purchase, or that have copyleft designs. But I wanted to know how Game Boy cartridges work. I was also excited to use the PIO functionality of the RP2040 microcontroller. Now, aft

NonRAID – fork of unRAID array kernel module

NonRAID - unRAID storage array compatible kernel driver NonRAID is an fork of the unRAID system's open-source md_unraid kernel driver for supported kernels, but targeting primarily Ubuntu 24.04 LTS, enabling UnRAID-style storage arrays with parity protection outside of the commercial UnRAID system. Unlike in UnRAID, where the driver replaces kernels standard md driver, the NonRAID driver has been separated into it's own kernel module ( md_nonraid ). This allows it to be easily added as a DKMS

Apple alerted Iranians to iPhone spyware attacks, say researchers

Apple notified more than a dozen Iranians in recent months that their iPhones had been targeted with government spyware, according to security researchers. Miian Group, a digital rights organization that focuses on Iran, and Hamid Kashfi, an Iranian cybersecurity researcher who lives in Sweden, said they spoke with several Iranians who received the notifications in the last year.

Android Earthquake Alerts: A global system for early warning

Earthquakes are a constant threat to communities around the globe. While we’ve gotten good at knowing where they’re likely to strike, we still face devastating consequences when they do. What if we could give people a few precious seconds of warning before the shaking starts? Those seconds can be enough time to get off a ladder, move away from dangerous objects and take cover. For years, that’s been the goal of earthquake early warning (EEW) systems. But the expensive seismic networks on which t

Samsung Galaxy S25 problems and how to fix them

Lanh Nguyen / Android Authority The Samsung Galaxy S25 series is here, and while it hasn’t been out for long, a few issues have already been reported on community sites like Reddit and Samsung’s official forum. This isn’t particularly surprising, as newly launched smartphones — regardless of the manufacturer — often come with bugs and other issues. Beyond these reported problems, the Galaxy S25 series may also experience minor issues common to Android devices or Samsung’s One UI. In this guide

Google Drive’s new tool makes it a breeze to skip right to the good part of your video uploads

The feature will be available to all users on the web version of Drive, but it only works on newly uploaded videos. It’s rolling out to Rapid Release domains starting today, with a wider rollout starting on August 20.

iOS 26 beta 4 adds more ‘liquid’ back to Liquid Glass design

iOS 26 beta 4 has just been released, and one of the biggest question on many testers’ minds has been answered.
