Wandering While Writing the SciSchmooze
Welcome Dear Reader,
I’m sitting in the comfort of an RV with near-freezing temperatures outside (elevation 2,100 m) as i write this SciSchmooze missive. The RV park has WiFi so it’s much like working from home. Here are a few observations you may find interesting.
ONE: Renewable energy generation is obvious out in the southwest deserts. East of San Diego on edge of the Borrego Desert are oodles of gargantuan wind turbines. Between there and Phoenix are square miles of concentrated solar power (CSP) and photovoltaic power plants.
TWO: Landscapes on our wanderings are amazingly beautiful. (Cue oohs & aahs.)
THREE: Water resources in the deserts are egregiously overused. The aquifers are drying up. I learned from an architect who lives near Prescott, Arizona that residents with their own water wells are forced to drill the wells deeper. His 100 meter-deep well dried up. He paid a lot to increase its depth to 200 meters. His neighbor had to increase his well to 600 meters. A nearby shopping center sank their well to 1,500 meters to guarantee water access for years to come. The local residents worry that businesses will quickly lower the water table so much that home owners will not be financially able to reach water for their personal wells.
FOUR: We visited the extensive cliff dwellings in Walnut Canyon National Park. They were built during the 125-year period from 1125 to 1250 CE. The level land above the near-vertial canyon walls was their farmland. Why they left is unknown but they may have become today's Hopi.
FIVE: We went to the 50,000 year-old, world's best-preserved meteor crater just 8 km off Route 66 - aptly named "Meteor Crater." Awesome huge. The crater is about 1,200 m in diameter, 170 m deep, and the rim rises 45 m above the surrounding land. Most of downtown San Francisco could fit on the crater's floor with the tip of the TransAmerica Pyramid poking slightly above the level of the rim. Before erosion of the crater's sides, the floor was over 200 m deeper. The "impactor" was an iron meteorite about 50 m in diameter. I ogled the reasonably-priced fossils in the gift shop (ammonites, nautiloids, trilobites, etc.) but came away with just a couple of small black glass tektites produced from the impact.
As we continued east on Route 66 (Interstate 40, actually) we paralleled a speeding four-engine freight train. Freight trains in North America are diesel-electric: a fossil fuel diesel engine runs a generator that supplies electricity to the electric motors that power the wheels. By simply adding a "battery car" next to the engines, the train need not burn any fossil fuel at all. While battery cars are sitting around recharging for the 'next' freight train, they can serve as power storage for the electrical grid. This could really work! And why stop at freight trains? Cargo ships may soon use wind power to reduce costs. And beneath the waves we naturally find sex.
We hope to reach New Mexico's White Sands this sojourn. Fossilized human footprints have been found there that might be over 20,000 years old. For a general overview of people in the Americas, i liked this video.

In spite of a gut-wrenching glitch, the James Webb Space Telescope (JWST) is scheduled to be launched this month from French Guiana. Here is an in-depth article on the JWST and the science that it will address - if all goes well.
If you would like a large JWST pin to wear or to gift, send an email to
david.almandsmith@gmail.com (only one) before noon Friday with an integer between zero and 1,000. We will then use a random number generator to select the target number and mail the pin to the person who chose the closest number. Dimensions: 3.5 x 4.5 x 0.2 cm.
The Omicron is the current COVID-19 variant in the news, but we could exhaust the Greek alphabet unless global vaccine hesitancy is radically reduced. Of course medical scams continue due to distrust and ignorance of medical science. Scammers are able to bill up to $8,000 for a few minutes of “electroacupuncture” quackery.
Good news: a Gallup poll of people in 113 nations shows that “science” is globally gaining in respectability. What makes the 6 o’clock news, however, are the disturbing instances of people refusing to respect scientific findings.
Take advantage this week of what your existence allows, be it adventure, compassion, learning, loving, conversation, … the list goes on and on and on,

Bay Area Skeptics
“Without curiosity you’re no longer probing for what is true. If someone says, “I saw Bigfoot the other day,” there are people who say, “Yeah, that’s great!” And people who say, “No, you’re full of shit” — both of those responses require no brain work. What is the brain work I would like to see more of? It’s: Tell me more. When did you see this? Where did you see it? Did you find other evidence? You start probing. It’s the absence of curiosity that concerns me.”

Optimal Transport and the Geometry of Collider Data - Livestream - 12/06/2021 11:00 AM
UC Santa Cruz
Collider experiments probe physics at the shortest distances by smashing protons together and measuring the debris produced by the collisions. However, it is challenging to infer the detailed short-distance physics from the distribution of debris measured by the detector. Over the past two years, the mathematical field of optimal transport has emerged as a promising tool for classifying collider events based on these distributions. In this talk, we will describe how optimal transport distances endow collider data with a geometric structure that can be used for ML-based event classification, and we will show how selecting optimal transport distances with good geometric properties can dramatically reduce computational effort.

Deciphering the prion code - 12/06/2021 04:00 PM
Stanley Hall Berkeley
Prions are proteinaceous infectious particles that allow the propagation and inheritance of structural information by proteins. Prions populate the tree of life, propagating as fibrils both in laboratory strains and in the wild. Disease-causing prions are responsible for transmissible spongiform encephalopathies, a wide range of neurodegenerative disorders affecting a variety of species. In humans, prion diseases include fatal familial insomnia, Creutzfeld-Jakob disease, and Kuru. The shape of infectious prions has long been thought to define their infectivity, but remained elusive for decades. My group recently determined the first atomic model of the structured core of a human prion fibril, and with it, unlocked clues to the molecular basis of prion infectivity, transmission and neurotoxicity. Using electron cryo-microscopy (cryoEM) methods, my group pursues structures of a variety of prions including disease-causing human prion variants, infectious prions in related mammals (elk, mouse, bank vole), and functional prions. Our studies aim to establish a rosetta stone for linking prion structure to function and present a starting point to the design of inhibitors or diagnostics that curb the effects of prion disease and offer insights into other amyloid diseases such as Parkinson’s or Alzheimer’s.

The Future of Filmmaking: AI for Volumetric Capture and Reconstruction - Livestream - 12/06/2021 07:00 PM
SF Bay Association of Computing Machinery
One picture is worth a thousand words, so what have been told with videos? What about 100 simultaneous videos to reconstruct every frame of life in a[masked] sq. ft dome? Is it enough to reconstruct and digitize us realistically? Similar to other industries, the entertainment industry is also being reshaped by AI, especially towards AR/VR consumption. Before the democratization of AI and data, such immersive experiences were lacking an essential element: photorealism. As the amount of data increased, our models got deeper, and the reality became decipherable.This talk will introduce recent deep learning advancements in 3D vision, reconstruction, and shape understanding techniques with a focus on generative models to digitize performances and scenes. Then we will shift gears with an overview of such models in 3D, and their progression on voxels, point clouds, meshes, graphs, and other 3D representations. Back to our studio, in addition to a discussion about how to process such large visual data, the challenges of scaling 10x over current capture platforms, and over 200x over state-of-the-art datasets will be presented. The talk will conclude with a sneak peek of upcoming VR/AR productions from the worlds largest volumetric capture stage at Intel Studios, as an example of real-world use cases of such AI approaches.

Designing polyelectrolyte nanocarriers to target cells and penetrate tissues - 12/07/2021 11:00 AM
Latimer Hall Berkeley
Polyelectrolytes have unique properties that make them advantageous for the design of nanomaterials for drug delivery. These polymers are water-soluble, have a large number of easily modified reactive side chains for attachment of ligands, and can exhibit charge that can be designed to be sensitive to physiological conditions such as pH, redox conditions or the presence of specific enzymes. This capability makes charge a very enabling tool in the targeting of nanoparticles to specific tissues, as well as in adapting the transport of nanoparticles through the tissue matrix. Furthermore, certain cells may also be more effectively targeted through the presentation of charge alone or in combination with moieties that introduce more specific interactions. In each case in which charge is a factor, there is also a complementary requirement to modulate the charge to enable interaction while affording effective diffusion and transport within tissues and organs. Examples include the use of charged polyamidoamine dendrimers for the penetration of drug into cartilage, and the use of polyethylene oxide shielding groups to modify the amount of charge exposed. Similarly, nanoparticles may be adapted to penetrate viscous barriers such as bacteria biofilm, but must exhibit an ability to modulate charge to enable attractive interactions without preventing significant uptake. Ultimately, it is also important to introduce other kinds of polyelectrolyte interactions, particularly when targeting specific cells such as immune or cancer cells; often these interactions include recepter-specific interactions, but non-specific interactions can also have a very significant role in directing particles to cancer or other disease-associated cell types. Ultimately, we seek to explore and exploit these interactions to target layer-by-layer and layered complex nanoparticles to a range of different cell types. Efforts on the use of high throughput sampling of nanoparticle-cell interactions on understanding nanoparticle-cell interactions and targeted uptake will also be discussed.

The Age of Invasions Meets the Age of Plastics: How Tsunamis, Megarafting, Coastal Development, and Climate Change May All be Related - Livestream - 12/08/2021 03:30 PM
Estuary & Ocean Science Center
The March 11, 2011 Tōhoku earthquake and tsunami sent an unprecedented volume of marine debris into the North Pacific Ocean which began to come ashore in North America and the Hawaiian Islands in 2012. Between the spring of 2012 and the winter of 2016/2017 we found nearly 400 living Japanese invertebrates and algae on Japanese Tsunami Marine Debris (JTMD) that landed in the Central and Eastern Pacific. Remarkably, JTMD, with living Japanese species has continued to arrive into 2021. Research commenced in 2019 in the “Garbage Patch” has now revealed that these Western Pacific coastal species appear to have newly colonized debris in the open ocean, successfully reproducing and maintaining multiple generations on the high seas.

Dangers of the “Lost Civilization” Trope - Livestream - 12/09/2021 07:00 PM
Bay Area Skeptics
Archaeological finds are often interpreted in popular science through the ‘lost civilization’ trope: once great metropolises and their people that mysteriously vanished in history. Although ruins suggest the abandonment of a specific location at a point in time, they do not suggest that its occupants and their culture disappeared; most often people simply moved somewhere else for a variety of reasons and their descendants and culture exist to this day in some form. By labelling a people as ‘lost’ in the past we erase or minimize their descendants and culture in the present. This talk focuses on Cahokia, one of the most frequently mentioned ‘lost civilizations’ in the world, and its post-abandonment history.

The James Webb Space Telescope: Great science will be launching soon! - Livestream - 12/10/2021 08:00 PM
San Mateo County Astronomical Society
The James Webb Space Telescope will be the most powerful and complex astronomical space observatory ever built. It will launch in December and will unfold itself before arriving in its final orbit in the Sun - Earth system about a month later. The large 6.5-m diameter JWST primary mirror and its infrared instruments will allow it to see some of the very first luminous objects that formed in the Universe shortly after the Big Bang. Other major science themes of JWST encompass studying the assembly of galaxies, the birth of stars and planetary systems, and planetary systems and the origins of life. JWST will be the premier astrophysics space observatory for NASA and the European Space Agency (ESA) over its 5 - 10 year mission lifetime. It will augment the Hubble Space Telescope, which primarily works at visible and ultraviolet light wavelengths. In addition to the topics covered in this talk, many scientists will use JWST to make discoveries that we have not yet imagined.
JWST employs many unique technologies, and the mission has been in development for 20 years. All major hardware components including the telescope, spacecraft, and all science instruments have been completed, and a significant amount of this work was done in the Bay Area and California. The completed integrated observatory will be launched from the ESA spaceport in French Guiana, and scientists from all over the world will use it. In this talk I will illustrate the mission's science potential and highlight some aspects of its technologies, launch, and operations plans.
