# gst: the sounds that occur when a soap bubble pops.

<< The popping sound of a bursting soap bubble is acquired using microphone arrays and analyzed using spherical harmonics decomposition. >>

the << acoustic emission originates mainly from the capillary stresses exerted by the liquid soap film on the air and that it quantitatively reflects the out-of-equilibrium evolution of the flowing liquid film. (..) the acoustic signature of violent events of physical or biological origin could be used to measure the forces at play during these events. >>

# gst: continuous, (not intermittent, perpetual) tremors and slips ...

<< Applying deep learning to seismic data has revealed tremor and slip occur at all times—before and after known large-scale slow-slip earthquakes—rather than intermittently in discrete bursts, as previously believed. Even more surprisingly, the machine learning generalizes to other tectonic environments, including the San Andreas Fault. >>

Machine learning reveals earth tremor and slip occur continuously, not intermittently. Los Alamos National Laboratory.  Feb 27, 2020.

https://m.phys.org/news/2020-02-machine-reveals-earth-tremor-intermittently.html

<< Slow earthquakes cyclically load fault zones and have been observed preceding major earthquakes on continental faults as well as subduction zones. Slow earthquakes and associated tremor are common to most subduction zones, taking place downdip from the neighboring locked zone where megathrust earthquakes occur. In the clearest cases, tremor is observed in discrete bursts that are identified from multiple seismic stations. By training a convolutional neural network to recognize known tremor on a single station in Cascadia, we detect weak tremor preceding and following known larger slow earthquakes, the detection rate of these weak tremors approximates the slow slip rate at all times, and the same model is able to recognize tremor from different tectonic environments with no further training. >>

# life: Black Death way revisited, the hypothesis, by Parag.

All these cases have links to Italy. 24 cases have been exported from Italy to 14 countries, and 97 cases have been exported from Iran to 11 countries. >>

<< A striking overlap exists between the path of today's viral spread and the path of the Black Death in the 1300s. >>

<< It is, of course, far too soon to make such dire predictions about Covid-19. But a striking overlap exists between the path of today's viral spread and the path that emerged in the 1300s. >>

<< The 14th-century plague is said to have originated in northwestern China, with bacteria contracted from marmots. Hebei Province bore the brunt of China’s plague fatalities, with 5 million of its residents perishing in the 1330s. Making its way westward via Silk Road merchants and caravans, the plague took several years to reach Persia, where it killed the Khan overlord Abu Said as well as half the population. In 1347, it entered Europe via Italy’s port of Genoa. >>

<< Now compare that to what we’re seeing today with Covid-19. This time around, the source of illness may have been pangolins or bats instead of marmots. It started in Wuhan, which just happens to be Hebei's capital. The coronavirus reached Iran in a couple of weeks, and so far has infected hundreds of people, even the country’s deputy health minister. Next to Iran, the next worst outbreak is in Italy, with more than 300 cases and rising quickly- and likely spreading through Europe exactly as the plague did centuries ago. >>

<< It is, perhaps no coincidence that, in the past two decades, China has been the origin of SARS, the swine flu, and now the Covid-19 coronavirus. Nor should we be surprised that Iran and Italy have emerged, once more, as waypoints for pandemic spread. What do Iran and Italy have in common today? They are two major anchors of China’s Belt and Road Initiative- also known as the 21st century’s new Silk Roads. >>

# life: inside the mysterious (i.e. secret) Yunnan cave, a key to the bizarre jump of the Chinese covid-19 virus

<< In 2004, deep in the wilderness of China’s Yunnan province, a group of scientists from the Wuhan Institute of Virology discovered a cave full of wild bats carrying hundreds of SARS-related viruses. Their work, published in a draft paper in 2005, ( Science. 2005 Oct 28;310(5748):676-9. Epub 2005 Sep 29.  https://www.ncbi.nlm.nih.gov/pubmed/16195424 ) unearthed the link between SARS (severe acute respiratory syndrome) and bats for the first time. >>

<< Now the virologist who led that study, Shi Zhengli, has revealed one of the strains found in that cave - the exact location of which is a closely guarded secret - is almost identical to the 2019-nCoV coronavirus which has so far killed at least 1,115 people and infected more than 45,000 worldwide. >>

<< Professor Shi ran the genome sequence of 2019-nCoV - now officially known as COVID-19 - through the bat-related virus database she built up over ten years and found it was a 96 per cent match to a virus found in the droppings of horseshoe bats. >>
