The Snows of Churyumov-Gerasimenko

You couldn't really be caught in this blizzard while standing by a cliff on Churyumov-Gerasimenko, also known as comet 67P. Orbiting the comet in June of 2016 the Rosetta spacecraft's narrow angle camera did record streaks of dust and ice particles though, as they drifted across the field of view near the camera and above the comet's surface. Still, some of the bright specks in the scene are likely due to a rain of energetic charged particles or cosmic rays hitting the camera, and the dense background of stars in the direction of the constellation Canis Major. Click on this single frame to play and the background stars are easy to spot as they trail from top to bottom in an animated gif (7.7MB). The 33 frames of the time compressed animation span about 25 minutes of real time. The stunning gif was constructed from consecutive images taken while Rosetta cruised some 13 kilometers from the comet's nucleus.

This is notably bad. Someone is currently targeting US utility infrastructure. Unlike earlier internet security incidents, at the end of this, a lot of people might end up dead.

systemd is a metastatic cancer on Linux. It was bad idea from the start. It must be destroyed if Linux is to survive.

This sort of thing is disturbing. Amazon should know better.

SHA-1 collisions are getting closer. If you are still depending on the security of SHA-1 in your system, you should stop now. BTW, I keep wondering what git is going to do about it...

Dear Lazyweb;

Looking for a small/cheap ARM machine with two gig E ports. Any suggestions? (No, I don't want to add a USB ethernet onto something, so don't suggest that.)

Why risk rejection of your paper when you can assure it?

Very important work that you should contribute money to.

The notion here is very simple: the mitochondrial genome has been slowly migrating into the nucleus over the last 1.5 billion years, but there are (in humans) a few dozen genes left out of the original thousands that have not yet moved. In the mitochondrion, the DNA is in a much more hostile environment than the nucleus, significantly more subject to mutation and degradation, which is why there's the selective pressure for them to move to the nucleus where they're better protected.

A number of diseases of old age are strongly thought to be linked to mitochondrial mutations.

Aubrey de Grey & Co. propose to artificially engineer the move of the remaining mitochondrial genes to cell nucleus in model animals. This should presumably give them a boost in longevity, but how much of a boost is hard to know -- my suspicion is that in mice not much of a change will be seen until other aging effects that kill mice in only a couple of years are fixed.

Anyway, this is a worthwhile cause. If you want to see real progress made towards fixing the diseases of old age and extending human life, you should donate.
