# 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. >>

<< 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.

<< Good afternoon to everyone online and in the room. (..) Since yesterday, Denmark, Estonia, Lithuania, Netherlands and Nigeria have all reported their first cases. 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. >>

# gst: NS3, how viruses self-cripple their genome replication machinery

<< An interdisciplinary team of researchers (..) has used computational chemistry, biochemistry and virology to uncover new information on how viruses such as West Nile, dengue and Zika replicate. Based on their research, the team said these viruses appear to cripple their own genome replication machinery.  >>

<< Nonstructural Protein 3 - or NS3 - in flaviviruses, (..) cause a number of diseases in humans. NS3 is a key enzyme that these viruses use to copy their genomes. >>

<< Most vaccines are developed by finding random mutations that slow down virus growth, (..) By understanding how viral enzymes like NS3 work in great detail, we can use that information to rationally design new mutant viruses that replicate less well and act better as a vaccine, without having to rely on chance to make the vaccine. This can help develop vaccines more rapidly and precisely. >> Brian Geiss.

# drugs: the inhibitor MCC950 of NLRP3, a small molecule tested against many large diseases

<< It seems too good to be true: a single drug that could treat humanity's worst afflictions, including atherosclerosis, cancer, Alzheimer's, Parkinson's and arthritis. All of these diseases have one thing in common-they involve an inflammatory protein called NLRP3. >>

The molecule << MCC950 blocks NLRP3 with high specificity in the lab. However, a small clinical trial of the compound by Pfizer showed weaker potency than expected, as well as liver damage at high doses. Some companies are now using MCC950 as a starting point to design safer and more effective molecules, while others are trying to find inhibitors unrelated to the compound. Currently, several NLRP3 inhibitors with a range of mechanisms are in preclinical, Phase I and Phase II trials >>
