Ross 128b: Analyzing a Planet by the Light of its Star
What we know about Ross 128b is that it orbits 20 times closer to its star than the Earth orbits the Sun, but receives only 1.38 times more irradiation than the Earth, with an equilibrium temperature estimated anywhere between -60 degrees Celsius and 20°C, the host star being small and relatively cool. But bear in mind that what we get from radial velocity is a minimum mass, because we don’t know at what angle this system presents itself in our sky. Now a team led by Diogo Souto (Observatório Nacional, Brazil) is attempting to deduce more about the planet’s composition using an unusual method: Analyzing the composition of the host star.

Reclaiming RSS – Aral Balkan
For those of you born into the siloed world of the centralised web, RSS is an ancient technology from Web 1.0 (“the naïve Web?”). Like most things back then, it does what it says on the tin: it enables you to easily syndicate the content of your site. People interested in following your posts subscribe to your feed and receive updates using their RSS readers. There is no Twitter or Facebook in the middle to algorithmically censor … ahem … “curate” your posts.

Babies in cages were no ‘mistake’ by Trump but test-marketing for barbarism.
Fascism does not need a majority – it typically comes to power with about 40 per cent support and then uses control and intimidation to consolidate that power. So it doesn’t matter if most people hate you, as long as your 40 per cent is fanatically committed. That’s been tested out too. And fascism of course needs a propaganda machine so effective that it creates for its followers a universe of “alternative facts” impervious to unwanted realities. Again, the testing for this is very far advanced.
