The hourglass is a robust consequence of spatial symmetries that translate
the origin by a fraction of the lattice period, he explained.

These observations help clarify the
origin of the powerful jet of gas streaming from the galaxy's center at a high
fraction of the speed of light: it is likely driven
by the swirling matter near the black hole's boundary.»
New evidence shows that the ocean also acts as a source of organic matter from biogenic
origin -LSB-...] Surface - active organic matter of biogenic
origin -LSB-...] enriched in the oceanic surface layer and transferred to the atmosphere
by bubble - bursting processes, are the most likely candidates to contribute to the observed organic
fraction in marine aerosol.
shows that natural VOC induced aerosols above the boundary layer are mostly of natural
origin (7:1), and comprise a 2:1 up to > 10:1 amount, compared to SOx (SO2 + sulfate) aerosols in the 0.5 - 10 km free troposphere, or 10 % of the total aerosol optical depth measured
by satellites... Add to that the effect below the boundary layer and the effect of other natural aerosols (natural fires, sea salt, sand dust, DMS, NOx), good for some 38 % of the < 1 micron
fraction of total aerosols (according to IPCC estimates)...
