Anyone who has suffered the indignity of splinter, a blister, or a paper cut knows that small things can sometimes be hugely annoying. You aren’t going to die from any of these conditions, but it’s still hard to focus when, say, the back of your right foot is rubbing a new blister against the inside of your not-quite-broken-in-yet hiking boots. I found myself in the computing version of this situation yesterday, when I was trying to work on a new Mac Mini and was brought up short by the fact that my third mouse button (that is, clicking on the scroll wheel) did nothing. This was odd, because I have for many years assigned this button to “Mission Control” on macOS—a feature that tiles every open window on your machine, making it quick and easy to switch apps. When I got the new Mini, I immediately added this to my settings. Boom! And yet there I was, a couple hours later, clicking the middle mouse button by reflex and getting no result. This seemed quite odd—had I only imagined that I made the settings change? I made the alteration again in System Settings and went back to work. Read full article Comments

For many of us, memories of our childhood have become a bit hazy, if not vanishing entirely. But nobody really remembers much before the age of 4, because nearly all humans experience what’s termed “infantile amnesia,” in which memories that might have formed before that age seemingly vanish as we move through adolescence. And it’s not just us; the phenomenon appears to occur in a number of our fellow mammals. The simplest explanation for this would be that the systems that form long-term memories are simply immature and don’t start working effectively until children hit the age of 4. But a recent animal experiment suggests that the situation in mice is more complex: the memories are there, they’re just not normally accessible, although they can be re-activated. Now, a study that put human infants in an MRI tube suggests that memory activity starts by the age of 1, suggesting that the results in mice may apply to us. Less than total recall Mice are one of the species that we know experience infantile amnesia. And, thanks to over a century of research on mice, we have some sophisticated genetic tools that allow us to explore what’s actually involved in the apparent absence of the animals’ earliest memories.
