Art and Science with the SciSchmooze

SciSchmooze 4.19.21

Hello Science Fans and Practitioners,

I haven't said it in awhile but I really like to think of science and art as complementing each other.  After all, they are both expressions of how we experience and interpret just about everything.  They both continue to grow, and inform us in new ways to see and experience just about everything.  In the last year we have seen so much change in how we perceive science and art due to changes in social and science based understanding.  Sadly there have been many tragedies that have brought us to understand and fight against many of the inequities that have been prevalent for so long, be they race, gender, circumstance, or privilege.  This isn't necessarily a new thing.  While there is much work to be done to overcome these challenges, there is still amazing research going on that some would call research for knowledge sake.  This would be what is called basic research by many.  Research that will yield new answers to new and existing problems and that will inspire humans to continue to grow, if we survive.

There are so many exciting things happening in science currently that it is a bit overwhelming if you think about all of it.  Kitty Hawk on Mars What's next… What can we do? There's so much!

Here are a few presentations to check out this week…   Is Artificial Intelligence Racist? Tue @ 11:00,  Ask the Scientist - Ed Gross  Wed @ 2:00,   After Dark Online: Earth Day  Thu @ 7:00

Further distractions for this week!  Predictions About the 21st Century: What They Got Right & Wrong has some great insights.  Do you ever wonder how some things get countedDon’t try to change someone else’s mind.

I hope that you have a week that is better than you planned or hoped for.

Improving neural network based equations solvers - Livestream - 04/19/2021 11:00 AM
UC Berkeley

Neural Networks (NNs) have ushered in new methods of constructing solution approximations to complex mathematical equations. However, especially in the context of Differential Equations (DEs), such approximations are often reliant on external methods/solutions to reliably estimate the errors associated with them. This occurs because cost functions are seldom explicitly dependent on the difference between the true solution and the NN based approximation. Thus, NN DE solvers retain an element of ambiguity vis a vis the fitness of their approximations that cannot seemingly be resolved without prior knowledge of an external solution - severely limiting their practicality and trustworthiness. We show how simple mathematical transformations upon the cost functions at hand can help address this issue, by creating explicit relationships between them and the error associated with the NN based approximations. We further show how such relationships allow for the construction of efficient error correction schemes.

Dipolar excitonic insulator in atomic double layers - Livestream - 04/19/2021 02:30 PM
UC Berkeley

The excitonic insulator (EI) is a charge insulating state that arises from the spontaneous formation of bound electron-hole pairs (excitons).  It presents an interesting platform for realizing quantum many-body ground states of bosons in solids, such as condensate and superfluid.  Although the concept has been known for sixty years, to date the EI remains poorly established because reservoirs for excitons generally do not exist.  In this talk, I will discuss the realization of an EI ground state with strongly interacting excitons in atomic double layers of transition metal dichalcogenide (TMD) semiconductors.  The double layer system enables the formation of electrical reservoirs for interlayer excitons and the continuous tuning of the exciton chemical potential.  I will present direct thermodynamic evidence of the EI state based on capacitance measurements. I will also discuss the exciton phase diagram that reveals both the exciton Mott transition and exciton quasi-condensation.

A New Measurement of the Positive Muon Anomalous Magnet Moment to 0.46 ppm - Livestream - 04/19/2021 03:30 PM
SLAC Colloquium

I present a new measurement of the positive muon anomalous magnetic moment a_μ=(g_μ-2)/2  from the Fermilab E989 experiment.   The quantity a_μ  is an exquisite probe of the quantum corrections of the muon interaction with the electromagnetic field.  The experiment is a follow up of the BNL E821 experiment, which saw a 3.7σ discrepancy from the Standard Model.   Due to the implications of possible new physics, it is of great interest to either confirm or refute the BNL result.  Our experimental technique utilizes the muon storage ring that was moved from BNL to Fermilab in 2015.    I will review the theory predictions and present our experimental technique, highlighting the innovations made by E989.    I present our first result based on a data set consisting of about 8 billion analyzed muon decays.   This result, representing only 6% of our expected final dataset, achieved an error of 0.46 ppm which is comparable to the BNL result.

Continuity: Discovering the Lessons behind the World’s Longest-lived Organizations - Livestream - 04/19/2021 05:00 PM
Long Now Foundation

One of Long Now’s founding premises is that humanity’s most significant challenges require long-term solutions, including institutions that caretake and guide the knowledge and commitment needed to work over long time scales.

However, there are a limited number of organizations that have managed to stay stable over many centuries, and in some cases, over a millennium. Long Now has been informally tracking these organizations for years, and in 02019 formed The Organizational Continuity Project to study long-lived institutions more formally.

Is Artificial Intelligence Racist? - Livestream - 04/20/2021 11:00 AM
Computer History Museum

Are AI technologies racist, by design, in their data collection, or through the optimization of their functions? Are uses of AI technology racist by application or outcome? Is there racism in the AI community of makers, companies, and funders? Is it possible that AI be used for anti-racist outcomes? This wide-ranging conversation will build on issues raised in the companion screening of award-winning documentary film Coded Bias.

Exploring the question of whether AI is racist, our expert panel will consider both what is being done today about racism in AI, and what could be done in the future from multiple perspectives.

Into the Pyrocosm: Fires, Fungi, and the Future of California's Forests - Livestream - 04/20/2021 07:00 PM
Mycological Society of San Francisco

Fire has been a major driving force in the ecology of California's landscapes since prehistoric times. In addition to 'natural' fires, indigenous people used extensive intentional burning practices to produce more favorable landscapes for human habitation.

But the frequency and intensity of fires has dramatically increased across the American west in the past decades, including many unmanaged, catastrophic 'megafires'.

How do fungi respond to these rapid changes in habitat composition?What role do they play in the recovery of burned forests?What might some possible futures look like for California's wild lands?

Christian will summarize some of the existing scientific literature on this topic, knowledge from indigenous communities, as well as his own findings from post-burn surveys in the CZU Fire and elsewhere.

Assessment of environmental DNA as a biomonitoring tool for vulnerable deep-sea habitats - Livestream - 04/21/2021 11:00 AM
Monterey Bay Aquarium Research Institute

High-throughput sequencing of targeted “barcode” loci in DNA extracted from marine environmental samples such as water and sediments has recently exploded in popularity due to the ability to generate a taxonomic community profile that usually surpasses what is obtainable from using traditional monitoring methods in terms of biodiversity and detection of rare taxa. Indeed, given the existing poor biodiversity inventory of many marine habitats coupled with their high cost and difficulty of access, environmental DNA (eDNA) biomonitoring of these remote ecosystems is attractive if reliable taxonomic inventories are obtained for a modest price and with little required sample material. As part of the DEEP SEARCH (DEEP Sea Exploration to Advance Research on Coral/Canyon/Cold seep Habitats) project, we collected water samples from eight JASON2 remotely operated vehicle (ROV) dives at sites within canyon, cold-seep, and cold-water coral reef habitats along the US Atlantic coast in April 2019. The use of an ROV allowed controlled water sample collection near features of interest. Duplicate one-liter seawater samples filtered through a 0.2 µm Sterivex and ten liters of seawater filtered through a 0.8 µm cellulose nitrate filter were collected from each Niskin. Metabarcoding of microbial 16S rRNA, metazoan 18S rRNA, and mitochondrial 12S and cox1 sequences from eDNA extracted from water samples were performed on an Illumina MiSeq. The 1L and 10L samples recovered largely the same communities. Differentiation among habitats in both microbial and metazoan community structure evidenced through multiple ordination and comparative analyses was clear. The strongest differentiation occurred between the shallow ( about 200 meters) and deep (about 2,000 meters) cold-seep habitats. The implications of our findings for biomonitoring in the deep sea, as well as plans for expanding our analyses to include other barcode loci, water column eDNA samples collected via CTD, and reference database augmentation through genome skimming, will be discussed during this seminar.

Estimation of Longfin Smelt Hatching Distribution, Abundance and Entrainment using Three-Dimensional Hydrodynamic - Livestream - 04/21/2021 03:30 PM
Estuary & Ocean Science Center

The distribution of larval fishes in estuaries is influenced by where they hatch and their movements after hatching. In the San Francisco Estuary, the threatened longfin smelt (Spirinchus thaleichthys) spawn adhesive eggs in shallow, fresh to brackish water. Attached eggs hatch and the larvae disperse seaward toward higher-salinity water. Actual locations of spawning are unknown, and cannot be inferred from distributions of larvae because intense tidal mixing erases the history of movement. Human interventions such as manipulations and diversions of freshwater flow may contribute to the ongoing decline of this species, and these effects depend on where the fish hatch. We combined connectivity estimates from hydrodynamic and particle-tracking modeling with trawl data in a Bayesian model to estimate the location and timing of hatching, as well as natural mortality of larvae and losses to freshwater diversions. Longfin smelt were estimated to have hatched further seaward than previously believed; estimated diversion losses were small compared to natural mortality, and therefore pose only a minor risk to the population. Similar methods could be applied in other estuarine and coastal systems where strong mixing reduces the ability of simpler models to predict spawning location and larval movement.

The Alchemy of Us: How Humans and Matter Transformed One Another - Livestream - 04/21/2021 05:00 PM
Long Now Foundation

In The Alchemy of Us, scientist and author Ainissa Ramirez examines eight inventions - clocks, steel rails, copper communication cables, photographic film, light bulbs, hard disks, scientific labware, and silicon chips - and reveals how they shaped the human experience.

Ramirez shows not only how materials were shaped by inventors but also how those materials shaped culture, chronicling each invention and its consequences - intended and unintended. Filling in the gaps left by other books about technology, Ramirez showcases little-known inventors - particularly people of color and women - who had a significant impact but whose accomplishments have been hidden by mythmaking, bias, and convention. Doing so, she shows us the power of telling inclusive stories about technology. She also shows that innovation is universal - whether it's splicing beats with two turntables and a microphone or splicing genes with two test tubes and CRISPR.

Rescheduled from October 6, 2020

Understanding the Role of Fire-Atmosphere Interactions on Fire Spread Using Observations - Livestream - 04/22/2021 05:00 PM
Cafe Scientifique Silicon Valley

Extreme fire behavior has been observed frequently during recent wildfires in the Western US, yet there is still limited understanding of the role of plume dynamics on fire spread. The Rapid Deployments to Wildfires Experiment (RaDFIRE) was the first coordinated meteorological field campaign dedicated to observing fire-atmosphere interactions during large active wildfires to better understand extreme fire behavior. Using a sophisticated suite of instruments, the field campaign sampled 26 wildfires from 2013-2018 in California and Idaho. While observations of active wildfires have shed light on processes associated with fire-atmosphere interactions, data collected from a small-scale and comprehensive field experiment (FireFlux2) provide context on the local processes responsible for fire spread that are difficult to observe when sampling large wildfires. Collectively, the RaDFIRE field campaign and FireFlux2 observations highlight the range of phenomena associated with fire-atmosphere interactions, especially plume dynamics, and will provide a valuable data set for the fire behavior modeling communities.

Hardcore Natural History: Marine Algae as Ocean Record Keepers - Livestream - 04/22/2021 06:00 PM
Pacific Grove Museum of Natural History

Join us as we speak to Dr. Emily Miller a research technician in the Monterey Bay Aquarium/Monterey Bay Aquarium Research Institute (MBARI) Incubator Initiative program with the Environmental Sample Processor (ESP) team. Emilly Miller will talk about how the team based at the Monterey Bay Aquarium used older algae specimens to extend the Bakun upwelling index back to 1878, 70 years before monitoring of upwelling began in Monterey Bay.

Planning for future ocean conditions requires historical data to establish more informed ecological baselines. To date, this process has been largely limited to instrument records and observations that begin around 1950. Marine algae from herbaria repositories may document long-term ecosystem processes and extend historical information records into the nineteenth century. The Monterey Bay Aquarium’s Ocean Memory Lab generates new information about the ocean’s past by combing through scientific collections, museums, and other historical archives. Emily Miller, the lead author of the study, was able to offer a new perspective on upwelling cycles and document these patterns to help understand the shifts in the foundation of the food web to make more informed conservation decisions in the future of Monterey Bay.

Wonderfest: Ask a Science Envoy: 'Awe & Big Data' - Livestream - 04/22/2021 08:00 PM

Wonderfest Science Envoys are early-career researchers with special communication skills and aspirations. Following short talks on provocative modern science topics, these two Science Envoys will answer questions with insight and enthusiasm:

UC Berkeley psychologist Rebecca Corona on The Many Faces of Awe - Awe is unlike any other emotion. It possesses the power to grab us, shake us, and change the way we see the universe. Psychological research in national forests and during the COVID-19 pandemic helps us to plumb the depths - and the many aspects - of awe. UC Berkeley statistician Stephen Bates on Being Honest with Big Data - Huge datasets now touch every part of our lives, and this explosion of information allows scientists to ask (and answer!) more questions than ever. But the more questions we ask, the more easily we fall prey to the "cherry-picking" fallacy. New ideas from statistics allow scientists to make honest assessments of the evidence in big data.

Understanding the Ice Shells of Ganymede and Callisto through Their Impact Crater Records - Livestream - 04/23/2021 12:00 PM
UC Santa Cruz

Both Ganymede and Callisto, Jupiter’s two largest moons, host numerous impact craters and basins on their ice shells. Although it is not yet possible to directly probe them, the wide ranges of impact crater sizes provide a possible avenue through which we can begin to understand the internal structures of these ice shells surrounding these moons. Here I will present findings from iSALE models looking at the development of complex craters and multiring basins and the implications for rheologic structure within Ganymede and Callisto’s ice shells. Icy complex craters show an inflection point in their depth-diameter measurements, which we show to be due to a transition from colder, conductive ice at the surface to warmer, convective ice in the subsurface. The depth of this transition indicates that the upper conductive portion of the ice shell has a conductive thermal gradient of approximately 10 K/km. We also set out to test if the onset of multiring basin morphologies are sensitive to the total thickness of the ice shell. Preliminary results show that thinner ice shells and higher thermal conditions - both conductive thermal gradient and convective ice temperature - facilitate multiring basin formation.

'Saving the Dark' Movie and Panel Discussion - Livestream - 04/23/2021 07:00 PM
Chabot Space and Science Center

"Saving The Dark" is a Documentary Movie on Astronomy and Light Pollution. It is about the significance of Astronomy and the night skies, effects of Light Pollution on Astronomy, human health, wildlife and beyond, what we can do to fight it. 

The movie will show what the people in cities are missing out on, the importance of Astronomy in our lives, the impact Astronomy can have on children, how Light Pollution costs a lot of money, affects our health, wildlife and our environment, show the work of nonprofits fighting to preserve dark night skies, tell what people can do at home to fight Light Pollution and talk to cities that have successfully handled this issue.

Observing the Sky: (Some) Astronomical Innovation From Then to Now - PART 2 - Livestream - 04/24/2021 07:00 PM
East Bay Astronomical Society

For more than 2000 years, innovative people have applied their ideas and insights into observing the universe. Unknown thousands of years ago, visual observers named sets of stars from the patterns they saw, sometimes using myths or animals, real or imagined, in their environments for the names. This became a convenience for astrologers and others talking about the sky. Planets were discovered and calendars were invented, and precession was discovered. Even computers and observatories were invented. More than a millennium ago, the first instruments for measuring star positions were invented. Used for surveying and navigation, improvements on these instruments and the developments of new ones led to new discoveries, especially when combined with new mathematical methods for calculation.

The invention of the telescope changed everything. Mountains and craters were visible on the Moon. Those moving points in the sky turned out not to be… worlds(?)! With moons! Telescopes and their mounts were improved, new inventions were adapted, and new methods of observation were applied to old and new problems by astronomers. The spectroscope, chemical photography, and the use of electricity and electronics literally opened up the universe to astronomers.

Continuing innovation on a variety of fronts has led to the present day, and a few years hence, with giant optical telescopes and other telescopes across and outside the electromagnetic spectrum. We can now see nearly to the edge of the visible universe and study processes occurring in the first few minutes of its existence. Amateur astronomers have not been left behind and benefit by many of the same innovations used by the professional community.

Innovations span the spectrum of invention, ideas, analysis, new applications of old and new technology, and even other astronomical discoveries. Learn how innovations have led to many famous, and not so famous but just as important, discoveries about the Solar System, the Galaxy, and the universe around us.

Gender Bias in Language Perception - Livestream - 04/26/2021 02:30 PM
Stanford Symbolic Systems Forum

An issue that has been debated for decades is whether there are gendered differences in communication styles and, if so, whether these differences can perpetuate power imbalances between people with different gender identities. If the answer to these questions is yes, then many have argued that those with less power can get ahead by talking like those with more power. For example, in response to studies showing that men interrupt women more often than the reverse in presidential debates and Supreme Court hearings, editorials argued that women should start interrupting men more often. However, recommendations like this rest on the assumption that people with different gender identities are perceived the same way when saying the same thing. Drawing on the results of an experiment where 5000 participants evaluated carefully manipulated conversations, this talk answers long-standing questions about how women and men are perceived when they interrupt each other.
