    Random thought for the day: every time you see f.lux turn your screen to nighttime colors, dawn is breaking on the other side of the earth.

    Our extensive review about has been published in Frontiers of Physiology - Chronobiology. May it serve as a solid scientific basis for discussions on all levels of society and may it quiet the usual hedonic treatment of the subject.

    The June Windows 10 patch (18362.207) fixes a bug that was affecting f.lux and color calibration in Windows. Please update if you're on an earlier 18362.

    This Fast Startup bug also affects the loading colour profiles. Not only will they not load and apply on start-up, you can't make colour profile changes because "that service is already used by another application". Which is terrible in all the ways.

    The May Windows 10 update (1903) has a serious color bug that shows up when you use Fast Startup. Here is information on what's going on and how f.lux users can work around it:

    From ANSES statement on blue blocking filters: clear lenses just don't work (so stop listening to the marketing). Also, if you're worried about blue light hazard, you need something way stronger.

    Science comic about exciting new work from , and others! Light at night affects basically all of us, but some people are really, really sensitive to it

    Some people are way, way more sensitive to light at night than others (picture of two people near lights in the evening, lights are labeled 40 lux)
    You can quantify a person's sensitivity to light by looking at how quashed their melatonin rhythms are by light. Melatonin gets produced in the body as a signal for "biological night" but light exposure in the evening suppresses that production, weakening the signal
    Researchers at Monash University looked at the melatonin suppression that occurred when 55 people were exposed to different light brightnesses-- from four hours before normal bedtime to one hour after. On average, it only took ~25 lux to suppress half the melatonin that would have been produced in the dark
    But even wilder then that? The tremendous variety of responses across people tested. (Graph showing person 50x more sensitive to light) If we didn't live in a society with artificial lighting, these differences would probably be no big deal-- we wouldn't spend much of our day in those medium-low light levels. But nowadays we do. Light at night is affecting pretty much all of us, and for some, the effects are huge.

    Thanks to for this piece on our new work in about the sensitivity of the human circadian system to light. Don’t be afraid of the dark!

    Huge new work showing >50x difference between the most and least sensitive circadian response, with an average response that's lower than previously thought.

    Circadian clock genes are expressed in all tissues in the body, with the highest levels found in skeletal muscles, according to some surprising new research.

    There's a memory leak in the Windows 18362 build (May update) that we've been unable to work around so far. To fix, we made f.lux restart (quietly) when RAM usage gets too high. Affected machines will get an update to v4.102 automatically. Hope for a better fix soon!
