The Science Thread

If you meant both forms of water, Alrik, I'm not certain but I think we probably do have both types. The two spin isomers of hydrogen occur in a natural mixture, so quite possibly in water also.

ALRIK: WHAT DID YOU MEAN????

We seem to have spun it in different directions.

The KATRIN-Experiment went online today. It's sort of a huge "scale" that's going to be used to indirectly measure the weight of neutrinos.

Wow, that's a pretty major find.

I would say it's a pretty (extremely) small find, of major importance.

pibbur who remembers Armstrong (not the bicyclist, but of course he remembers him as well, for completely different reasons).

That's what the wife said, right? ;)
 
Telescope Upgrade Produces Stunningly Clear Views of Space
New photographs released by the European Southern Observatory show how severe the effect can be — and how a technology called adaptive optics can reduce the problem [of blurring caused by turbulence in Earth's atmosphere].
(..)
The system compensates so effectively for the atmosphere that the test images taken with the system are about as sharp as photographs from the Hubble Space Telescope — which doesn't have to deal with the phenomenon at all.

The Very Large Telescope's views of Neptune, with and without its new adaptive-optics module, show how significant an improvement the new system represents.

Pretty sweet. And the technique is also going to be used for the extremely large telescope in Chile that is currently under construction.

It's like they corrected miopia on Earth-based telescope, lol.

Fish seem to recognize themselves in the mirror. Well, the cleaner wrasse anyway:

Chimpanzees, elephants, dolphins and corvids have passed the mark test. “The marktest in which a coloured mark is placed on a test subject in a location that can only be viewed in a mirror reflection, is held as the benchmark behavioural assay for assessing whether an individual has the capacity for self-recognition.”

This year's IgNobel prize for rollercoaster kidney stone therapy.

Yes, it actually makes sense. Most renal stones come out by themselves, and it doesn't surprise me that the accelerations supplied by a rollercoaster might accelerate the process. Why didn't I think of this before?

On a sidenote, for stones that remain stuck, focused ultrasound can be used to tear them to pieces (lithotripsy). In Norway the apparatus involved (the lithotriptor) is sometimes referred to as a "steinknuser" which translates to "stone crusher" in English. Considering that in Norwegian the common name for a testicle is "stein" ("stone") and …. *shivers*.

pibbur who, AFAHK, so far hasn't had any stones besides the two resting down under.

I think I would definitely give a day on the rollercoasters a try, before visiting the Norwegian stone crushers.
