A correction notice has been issued for a previously published research paper on catalyst-free, microdroplet-mediated conversion of waste plastic into diacids. The notice is published under a Creative Commons Attribution 4.0 International License, allowing free reuse and distribution with proper credit.
The publisher has released an author correction to a previously published study on long-read sequencing that revealed pre-meiotic gene conversion in sperm. The correction notice itself does not detail the specific errors being addressed, focusing instead on licensing and reuse terms under Creative Commons Attribution 4.0.
The 2014 post traces how the Lwan web server's integer-to-string conversion evolved from using snprintf() to a naive divide-and-modulus algorithm that built digits in reverse and then flipped the string. The author then replaced it with a version that writes digits directly into a buffer from the end backwards, avoiding the separate string-reversal step and using a buffer sized via a trick based on multiplying sizeof(int) by three.
Xreal has released its One Pro Plus display glasses for $599, upgrading brightness to 1,200 nits from 700 nits on the earlier One Pro model. The new version adds extra visual settings, including a 'Reading' mode, and a smoother AI-driven 3D conversion feature for 2D content, but otherwise keeps the same design, USB-C tethering and onboard chip as its predecessor.
A maker documented converting a stock Razor A5 Lux push scooter into an electric vehicle by mounting a Hercules cordless drill to drive the front wheel through a keyed shaft and one-way bearings. The build used a welder, a 3D printer, and parts sourced from Harbor Freight, Amazon, and McMaster-Carr, relocating the drill's trigger to the handlebars for throttle control. The result tops out around 10mph and gets roughly two miles of range from a 5 amp-hour battery.
An Entrepreneur contributor argues that website redesigns typically start with complaints about outdated design or poor conversion, but the harder work is confronting unresolved business choices—like which audiences, services, or divisions actually deserve priority. The piece notes that sitemaps built up over years often reflect a company's accumulated history rather than a deliberate current strategy, with old pages persisting simply because no one removed them.
A contributor column for Entrepreneur argues that when company growth slows, founders should resist immediately trying new tactics like SEO, ads or pricing changes. Instead it advises diagnosing the root cause first, since growth analytics reveal where a funnel breaks down but not why. The piece recommends customer interviews to uncover the gap between expected and actual customer behavior before choosing a fix.
A traveler returning from a trip through France, Spain and Portugal reports that Dynamic Currency Conversion, the practice of letting merchants bill purchases in a tourist's home currency instead of the local one, has become harder to avoid. Many payment terminals now default to charging in dollars automatically, often without a clear prompt asking the customer to choose, making it easy to unknowingly accept a worse exchange rate.
A longtime small-business marketing consultant argues that many companies build attractive websites that fail to turn visitors into customers. He recommends prioritizing clear usability, straightforward instructions and essential information over stylish but unclear design, and suggests using digital retargeting ads and direct-mail postcards to re-engage visitors who leave without converting.
Calibre, the open-source e-book library management tool, has introduced a feature that lets users generate custom book covers using AI. This joins its existing suite of tools for organizing, converting and syncing e-books across formats and devices.
ZDNET published a guide showing how an unused computer monitor can be converted into a functional television, typically by adding an external streaming device or tuner and speakers since most monitors lack built-in audio and tuning hardware. The guide is part of ZDNET's product recommendation coverage, which discloses that the outlet may earn affiliate commissions from linked retailer purchases.
Researchers extracted high molecular weight DNA from 15 sperm samples donated by 13 men from the TwinsUK cohort and an external biobank, using a modified extraction protocol designed to break down the tightly packed protamine structure of sperm DNA. Applying long-read sequencing to these samples, the team identified evidence of gene conversion occurring before meiosis, a genetic recombination process not previously well characterized at this resolution in sperm cells.
