The Best Mattress Toppers I've Tried (2026): Supportive, Plush, Memory Foam

WIRED

I Tested the Best Mattress Toppers for a Good Night's Sleep These toppers will transform your mattress into exactly what you need, whether that's a super-plush pillow top, memory foam, or targeted back support. My hunt for the best mattress toppers has taught me how transformative they can be. It started years before now, when I was throwing my back out nightly on a thin futon mattress in my fresh-out-of-college days. I tried a few cheap sheets of foam that barely helped with my back pain . I gave up for a while and instead switched to a too-soft mattress (equally problematic), until finally finding the right combo: a firm, supportive mattress with a nice mattress topper on top to support my problem areas and side-sleeper shoulder pain. These toppers can alleviate your aches, sink you into insanely comfortable memory foam, and even pack supportive coils like a mattress. My favorite toppers range from soft wool layers and memory foam to firm and even hybrid toppers (yes, you can get mattress toppers with springs in them) to find the best option for you and your mattress. Curious what you should get? Read on to find my best mattress toppers for everything from back pain issues, college students, and more. All prices below are for queen-size toppers.

The GPU Phase Folding and Deep Learning Method for Detecting Exoplanet Transits

arXiv.org Artificial Intelligence

This paper presents GPFC, a novel Graphics Processing Unit (GPU) Phase Folding and Convolutional Neural Network (CNN) system to detect exoplanets using the transit method. We devise a fast folding algorithm parallelized on a GPU to amplify low signal-to-noise ratio transit signals, allowing a search at high precision and speed. A CNN trained on two million synthetic light curves reports a score indicating the likelihood of a planetary signal at each period. While the GPFC method has broad applicability across period ranges, this research specifically focuses on detecting ultra-short-period planets with orbital periods less than one day. GPFC improves on speed by three orders of magnitude over the predominant Box-fitting Least Squares (BLS) method. Our simulation results show GPFC achieves $97%$ training accuracy, higher true positive rate at the same false positive rate of detection, and higher precision at the same recall rate when compared to BLS. GPFC recovers $100\%$ of known ultra-short-period planets in $\textit{Kepler}$ light curves from a blind search. These results highlight the promise of GPFC as an alternative approach to the traditional BLS algorithm for finding new transiting exoplanets in data taken with $\textit{Kepler}$ and other space transit missions such as K2, TESS and future PLATO and Earth 2.0.


How AI Writing Assistants Can Help You Create More Quality Content Faster

#artificialintelligence

The content creation process is a time-consuming and tedious task for many writers. Producing a high-quality article can take a lot of time, effort, research, and creativity to complete. It's no wonder that a lot of people are turning to artificial intelligence writing assistants in order to get the job done faster. These programs use algorithms that scour millions of articles and then rewrite them based on what they find. In this blog post, we'll go over some ways AI writing assistants can help you create more quality content faster!


Unmanned ship sailing itself around the ocean could be hacked, experts warn

The Independent - Tech

Nasa has announced that it has found evidence of flowing water on Mars. Scientists have long speculated that Recurring Slope Lineae -- or dark patches -- on Mars were made up of briny water but the new findings prove that those patches are caused by liquid water, which it has established by finding hydrated salts. Several hundred camped outside the London store in Covent Garden. The 6s will have new features like a vastly improved camera and a pressure-sensitive "3D Touch" display


The Bounded Bayesian

arXiv.org Artificial Intelligence

The ideal Bayesian agent reasons from a global probability model, but real agents are restricted to simplified models which they know to be adequate only in restricted circumstances. Very little formal theory has been developed to help fallibly rational agents manage the process of constructing and revising small world models. The goal of this paper is to present a theoretical framework for analyzing model management approaches. For a probability forecasting problem, a search process over small world models is analyzed as an approximation to a larger-world model which the agent cannot explicitly enumerate or compute. Conditions are given under which the sequence of small-world models converges to the larger-world probabilities.


Period Estimation in Astronomical Time Series Using Slotted Correntropy

arXiv.org Machine Learning

In this letter, we propose a method for period estimation in light curves from periodic variable stars using correntropy. Light curves are astronomical time series of stellar brightness over time, and are characterized as being noisy and unevenly sampled. We propose to use slotted time lags in order to estimate correntropy directly from irregularly sampled time series. A new information theoretic metric is proposed for discriminating among the peaks of the correntropy spectral density. The slotted correntropy method outperformed slotted correlation, string length, VarTools (Lomb-Scargle periodogram and Analysis of Variance), and SigSpec applications on a set of light curves drawn from the MACHO survey.
