# gst: sand dunes 'communication' via turbulent swirls

<< Even though they are inanimate objects, sand dunes can 'communicate' with each other. A team (..) has found that as they move, sand dunes interact with and repel their downstream neighbours. Using an experimental dune 'racetrack', (they) observed that two identical dunes start out close together, but over time they get further and further apart. This interaction is controlled by turbulent swirls from the upstream dune, which push the downstream dune away.  >>

# chem: more on the weirdness of water, "T" and "non-T" Tetrahedral arrangements

<< the unusual properties of liquid water, if compared with other liquids, has puzzled us for centuries because the basic structure of liquid water has remained unclear and has continued to be a matter of serious debate. >>

AA << show that there are two overlapped peaks hidden in the apparent “first diffraction peak” of the structure factor. One of them (ordinary peak) corresponds to the neighboring O–O [Oxygen-Oxygen bond] distance as in ordinary liquids, and the other (anomalous peak) corresponds to a longer distance. >>

the << anomalous peak arises from the most extended period of density wave associated with a tetrahedral water structure and is to be identified as the so-called first sharp diffraction peak >>

<< In contrast, the ordinary peak arises from the density wave characteristic of local structures lacking tetrahedral symmetry. This finding unambiguously proves the coexistence of two types of local structures in liquid water. >>

# gst: tiny deviations (inside a phase transition) to avoid a near-complete annihilation.

<< Recently discovered ripples of spacetime called gravitational waves could contain evidence to prove the theory that life survived the Big Bang because of a phase transition that allowed neutrino particles to reshuffle matter and anti-matter, >>

<< According to the Big Bang theory of modern cosmology, matter was created with an equal amount of anti-matter. If it had stayed that way, matter and anti-matter should have eventually met and annihilated one to one, leading up to a complete annihilation.

But our existence contradicts this theory. To overcome a complete annihilation, the Universe must have turned a small amount of anti-matter into matter creating an imbalance between them. >>

# phys: nature does not always respect symmetry, the hypothesis

<< Physicists have been looking for laws that explain both the microscopic world of elementary particles and the macroscopic world of the universe and the Big Bang at its beginning, expecting that such fundamental laws should have symmetry in all circumstances. However, last year, two physicists found a theoretical proof that, at the most fundamental level, nature does not respect symmetry. >>

<< To try to understand gravity on the quantum level, Hirosi Ooguri, (..) and Daniel Harlow, (..) started with the holographic principle. This principle explains three-dimensional phenomena influenced by gravity on a two-dimensional flat space that is not influenced by gravity.  >>

<< The researchers showed that symmetry only affects the shaded regions in the diagram, not around the spot in the middle, thus there cannot be global symmetry.  >>
