Today's Sunday Funny is funny mostly because of the title of the paper. It's a perfectly serious paper about physics, but it's got Sausages, and Kinks. And Jeans.

Sausage and kink oscillations in astrophysical disk configurations.

The development of hydrodynamic oscillations in various rotating astrophysical disks ranging from planetary rings to galaxies is studied analytically. The dispersion relation of wave propagation is derived. Modes of oscillation are examined from this dispersion relation that are suitable for obtaining information not just on oscillations but also on some instability properties of the disk-shaped structure. It is shown that unstable oscillations of different types, sausage compression and kink bending, may be excited effectively due to the Jeans gravitational instability and the kink transverse instability, respectively. The obtained results for the sausage oscillations may be applicable for such phenomena as the appearance of the in-plane spiral and circular structures, while the case for the kink mode is more relevant for the systematic vertical corrugations of astrophysical disks.

I love science.
Today's Sunday Funny comes to you courtesy of Biochembelle. It's not a bad paper at all, in fact it's very useful, but the title is particularly well chosen. Sometimes you just gotta go for the low hanging fruit...
I may or may not have found this on the internet. Or I may or may not have made this for a friend who has been having a hard time of it.

Remember that whole "avocados and eggplants go straight to the womb because they shaped like wombs"? It turns out that's a THING. Like, a thing that people actually believe.

Yes. Josh found the video via a Christian forum...that was mocking it ruthlessly. Good people.
Humans don't do it, but we surely BELIEVE that we do.

Belief in lunar effects on human behavior.
University of New Orleans.
Questionnaires sent to 325 people indicated that 140 people (43%) held the personal belief that lunar phenomena alter individual behavior. Specifically, mental health professionals (social workers, master's clinical psychologists, nurses' aides, LPNs) held this belief more strongly than other occupational groups.
This week's Sunday Funny brought to you by Biochembelle. Given the one two weeks ago, I'm starting to wonder why on earth she knows QUITE so much about pyramid alignment.

The present study was aimed to find out whether a change in the alignment of the pyramid from the north-south axis causes any variation in the effects produced by it on plasma cortisol levels and markers of oxidative stress in erythrocytes of adult-female Wistar rats. Plasma cortisol and erythrocyte TBARS levels were significantly lower whereas erythrocyte GSH was significantly higher in rats kept in pyramid that was aligned on the four cardinal points--north, east, south and west, as compared to normal control rats. Although there was a significant difference in the plasma cortisol level between normal control group and the group of rats kept in randomly aligned pyramid, there was no significant difference between these two groups for the other parameters. Erythrocyte TBARS levels in the group of rats kept in the randomly aligned pyramid was significantly higher than that in the group kept in the magnetically aligned pyramid. The results suggest that the north-south alignment of the pyramid is crucial for its expected effects.
I always wondered why I was so stressed. Obviously I have been misaligning my pyramids due to their northeasterly orientation.
