    I've used the Logitech MX Master 3 as my primary productivity mouse since it came out in 2019. I've tested dozens of mice since, but none juggled a decent number of programmable buttons, advanced wireless capabilities, multi-device control, and long-term comfort as admirably as the MX Master 3. Today, Logitech released a revamped version, the MX Master 3S .

    It follows in Master 3's footsteps of wireless mouse excellence but doesn't introduce enough improvements to warrant ditching my MX Master 3 and opening my wallet again.

    As you might have guessed by the mild moniker modification, the 3S is slightly different from the 3. The new mouse has quieter left- and right-click buttons, and it supports higher sensitivity, so your cursor can move farther with less physical mouse movement—and that's it.

      Study of reproducibility issues points finger at the mice / ArsTechnica · Wednesday, 11 May, 2022 - 16:06 · 1 minute

    Study of reproducibility issues points finger at the mice

    Over the last decade or so, the science community has been concerned about what has been called the "reproducibility crisis": the apparent failure of some significant experiments to produce the same results when they're repeated. That failure has led to many suggestions about what might be done to improve matters, but we still don't fully understand why experiments are failing to reproduce results.

    A few recent studies have attempted to pinpoint the underlying problem. A new study approached reproducibility failure by running a set of identical behavioral experiments in several labs in Switzerland and Germany. It found that many of the differences come down to the lab itself. But there's also variability in the results that can't be ascribed to any obvious cause and may just arise from differences between individual mice.

    Try and try again

    The basic outline of the work is pretty simple: Get three labs to perform the same set of 10 standard behavioral experiments on mice. But the researchers took a number of additional steps to allow a detailed look at the underlying factors that might drive variation in experimental results. The experiments were done on two different mouse strains, both of which had been inbred for many generations, limiting genetic variability. All the mice were ordered from the same company. They were housed in identical conditions and were tested while they were the same age.

      Razer’s new wireless mouse offers light weight, tasteful look / ArsTechnica · Tuesday, 10 May, 2022 - 15:00 · 1 minute

    If you prefer a mouse that glides across a mousepad—or a glass surface, in this case—with minimal effort, finding a lightweight, cordless one is a good move. Lightweight mice are often LED-laden or hole-riddled pieces that look odd in most settings outside of a gaming den. But Razer's Viper V2 Pro announced Tuesday is a 2.05-ounce (58 g) wireless mouse carrying a muted look that can accommodate more traditional-looking setups.

    Razer is primarily known for flashy, snake-clad PCs and peripherals aimed at gamers. The Viper 2 Pro, with an optical sensor that supports an adjustable DPI (dots per inch, see more in our PC mouse terms article) of up to 30,000 and extreme features like adjustable liftoff distance, is also aimed at PC gamers. But with its muted black or tasteful white design and symmetrical shape, you might not notice it at first. Although, spotting the angular lines under the left and right-click buttons and the subtler three-headed snake might provide clues.

    Still, there's no RGB logo, and that took 0.1 ounces (2.7 g) off the mouse's weight compared to its predecessor, the 2.61-ounce (74 g) Razer Viper Ultimate , and will also help conserve battery life. The only real pop of color is the light south of the scroll wheel, which signifies which DPI setting you're currently using.
