Schmoozing into Orbit

David Almandsmith

I just bought 25 raffle tickets for a multi-day orbital journey. Since each orbit takes about 90 minutes, i’ll make 16 orbits each day while i’m in orbit. First, however, i need to win the raffle. ¿Would you like to buy a few tickets? Just donate to St. Jude Children’s Research Hospital. Each dollar you donate in February gives you one raffle ‘ticket.’ The winner will ride in a SpaceX Dragon capsule with three other folk. Because of olfactory fatigue, you shouldn’t be too concerned about spending a few days in an unventilated capsule with three others - - and no bathroom - - and no DoorDash deliveries. (Hmmm. ¿Have you read or seen “No Exit” by Jean-Paul Sartre?)

Mars Missions:

Other space news:
According to cosmologists, only about 5% of the visible universe is composed of normal (baryonic) matter. Astronomers had only been able to detect about half of that. Then last year, astronomers used data from FRBs (Fast Radio Bursts) to find evidence that the missing mass was composed of thin clouds of gas. Last week, astronomers in Australia announced they were able to ‘see’ an otherwise invisible stream of gas using a clever method.

Earth news:
The United States is back in the Paris Climate Agreement, General Motors plans to phase out fossil-fueled vehicles by 2035, and South Korea just announced committing $43 billion to build the world’s largest offshore wind farm.

Geothermal energy production got an undeserved bad rap from the Tech Xplore website. A careful reading of the scientific paper reported on, reveals that only poorly-designed geothermal facilities would have longevity problems. The “quote” at the end of the Tech Xplore article appears to be a distorted version of a quote in the published research. Another example why it’s important to critically assess information - whatever the source.

Fun stuff:
I sometimes binge-watch live animal cams. Here is a list of a few out of thousands available: Giraffe, Rhino, Cape Buffalo; Jellies; Tembe Wildlife Park; California Condor; Platypus; Shark; Human, Bald Eagle. Some of these are in different time zones. A couple of these i learned about from Science in View, a science website hosted by Oakland resident Dave Boitano.

Deep Dive into Biology:
When our immune system produces antibodies to ‘combat’ an infection, the antibodies are typically about 1,400 amino acids in length. Then along came the discovery of antibody fragments in camels, alpaca, llamas, and other cameloids. These fragments are about 1/10th the size of antibodies and surprisingly, they also combat infections. They have been named “nanobodies.” They are ‘relatively’ easy to create in labs in billions of versions. Several labs have announced success in generating nanobodies that combat SARS-CoV-2 infections, i.e. COVID-19. Cool.

My livestream picks of the week:

Every doggone time, i forget to join several of my own picks. So this week i’ve told my phone to zap me in time to participate or watch. I recommend you do likewise for the ones you wish. (The Thursday pick is brought to you by the Bay Area Skeptics, of which i am a member.)

Ping Pong Balls & Passports
The Public Broadcasting Service, Joe Hanson, and 500 ping pong balls seek to explain and demonstrate phenomena of infectious diseases. (Put a white & red knit cap on Joe and - voila! - you’ve just found Waldo!)

Decades ago, i had to present a certificate showing that i had received my smallpox vaccine before i was allowed to travel to Europe. That requirement was officially dropped in 1981. However, countries around the world are reviving the practice of issuing vaccination certificates in response to the current pandemic. Forget paper certificates, however. Electronic vaccination passports are now being designed that will show your most recent COVID test and its result as well as vaccination information for a number of infectious diseases.

Living is a fantastic voyage. Enjoy the trip.

Please in my backyard: Developing community-owned renewable energy - Livestream - 02/08/2021 11:30 AM
Stanford Energy

One challenge that renewable energy developers increasingly face  - particularly in land-restricted and urban areas - is community opposition to industrial development in their backyard. And when clean energy is installed, it rarely benefits low income communities and communities of color. At Shake Energy Collaborative, we are exploring a new way of developing renewable energy projects in partnership with disinvested communities so that the projects we build are not just tolerated by the neighbors but advocated for and owned by them. In this seminar, Iʻll share some of our successes in developing bi-directional relationships with communities in Fresno, CA and Molokaʻi, HI as well as some of our challenges in working with utilities to develop these communities’ visions. Iʻd love to discuss with all of you what our visions for the future of equitable energy looks like and what our respective roles will be in realizing it.

Serving Like an Organization: How Food-Service and Retail Workers Interpret Their Interactions With Customers - Livestream - 02/08/2021 12:00 PM
Berkeley Institute for Data Science

How do food-service and retail workers interpret interactions with customers? Researchers have identified many novel sociological processes, specific to service work, that seem to pull service workers in opposing directions, leaving them either better or worse off. In this talk, I argue that these opposing processes are not mutually exclusive. Due to the nature of the job, service workers may experience a series of divergent interactions with customers during their job tenure. In order to account for these conflicting experiences, I take an orientations approach - analyzing summative judgments about customers and their associations with job satisfaction. I draw on a novel dataset of over 15,000 job quality evaluations from 10 food-service and retail companies, collected from Glassdoor.com. This website allows workers to post written reviews of the pros and cons of their job, as well as to provide numeric ratings of their job quality. Qualitatively coding a subset of 1,000 reviews, I find that frontline workers express three distinct orientations towards customer interactions: an occupational orientation - where customers are an inescapable occupational hazard or benefit, an organizational orientation - where positive and negative interactions are a result of organizational strategies, or as a source of intrinsic satisfaction. Using computational text analysis, I code the remaining 14,000 reviews to investigate how occupational and organizational orientations towards customers are related to job ratings. I find that an organizational orientation is associated with more extreme ratings of the job.

An Ultra-Compact X-ray Free-Electron Laser - Livestream - 02/08/2021 03:30 PM
SLAC Colloquium

Recent advances in high gradient cryogenic Cu structure RF research open the door to use of surface electric fields between 250 and 500 MV/m. Such structures can enable a new generation of photoinjectors with brightness an order of magnitude beyond the state-of-the-art. Further, one may accelerate these beams to GeV scale in ~8 m. Such an injector, when combined with IFEL bunching techniques can produce multi-kA beams with 50 nm-rad emittance. These beams, when injected into short-period (1-10 mm) undulators enable ultra-compact X-ray FELs having university-scale-lab footprints*. We discuss the design and performance of this compact XFEL, which promises photon-per-pulse production a few percent of existing XFELs. In the context of a burgeoning project centered at UCLA to develop this instrument, we review implementation issues including collective beam effects, compact X-ray optics systems, and various technical challenges. To illustrate the potential of such a light source to fundamentally change the current paradigm of XFELs with their limited access, we examine transformative applications in biology, chemistry, materials, and atomic physics.

Biomass Energy and Natural Climate Solutions: A Meaningful Piece of the Solutions Portfolio - Livestream - 02/08/2021 04:00 PM
Stanford Energy Seminar

Most scenarios for ambitious decarbonization rely on photosynthesis-based technologies for a substantial fraction net GHG emissions reductions.  These technologies potentially contribute emissions reductions through providing low-emissions energy, coupling with CCS to produce energy with negative emissions, increasing the carbon content of the biosphere, or decreasing emissions from land-use change.  While all these options will be attractive at some scale, setting realistic targets is challenging, largely because the constraints and trade-offs for these technologies are so different than for other components of a decarbonization strategy.  In general, limits imposed by land and water requirements, challenges with governance and implementation, and sensitivity to climate change argue for the expectation that these technologies will provide a meaningful, but not dominant, fraction of the decarbonization solutions portfolio throughout the 21st century.

From Particles to Power: How photons, electrons, and ions determine the efficiency of perovskite solar cells - Livestream - 02/08/2021 04:00 PM
What Physicists Do @ Sonoma State University

Assuming business as usual, our planet is projected to warm more than 4C in the next 80 years. Those four degrees mean more chaotic weather, increased food scarcity, unprecedented flooding, along with many other impacts of global warming - unless we do something radical to cut greenhouse gas emissions. While there is general agreement that solar energy will play a huge role in this task, scientists like Dr. Belisle are trying to push the very limits of what solar technology can do by designing perovskite solar cells - a novel renewable energy material that is poised to have high efficiency, minimal cost, and be manufactured extremely quickly to mitigate the impending devastation of climate change.

In this talk we’ll discuss the fundamental properties that make this new class of optoelectronic materials a game-changer in the field of solar energy. With tunable absorption, unprecedented defect tolerance, and mixed electronic-ionic conduction, perovskites require new design rules and new physical models of understanding for their use in solar cells. In light of these unique properties, I’ll explain how photons, electrons, and ions interact to affect the performance of perovskite solar cells, and how my lab is using optical and structural characterization to improve our knowledge of fundamental perovskite properties to enable even higher efficiency devices.

Speaker: Dr. Becky Belisle, Wellesley College

Moiré Magic - Livestream - 02/08/2021 04:15 PM
UC Berkeley

Moiré materials are formed when two-dimensional crystals are overlaid with a small difference in lattice constant or orientation.  When the two-dimensional crystals are semimetals or semiconductors, the low energy states of moiré materials are described by periodic continuum models and have the electronic properties of artificial crystals with lattice constants on the tens of nanometer scale, allowing the number of electrons per atom to be varied widely using electrical gates.   My talk will focus on the particular case of graphene bilayer moiré materials, which exhibit a rich set of strongly correlated electron states, including superconductors and insulating orbital magnets, when twisted close to a magic relative orientation angle at which the electron velocity at the Fermi level vanishes.   Electronic correlations in Magic Angle Twisted Bilayer Graphene (MAtBG) are strong because the low-energy moiré superlattice bands are very narrow and because the flat bands form an octet that is the direct product of spin, valley, and sublattice internal degrees of freedom.  I will discuss efforts, still very much in progress, to settle on answers to some of the following questions.  Does the flat-band dispersion that remains at the magic twist angle play a key role in controlling the phase diagram?  How does octet symmetry breaking depend on the moiré band filling factor? Is superconductivity in MAtBG mediated by electron-phonon interactions or by some other mechanism?

Next Stop: How to Build Hyperloop - Livestream - 02/09/2021 09:00 AM
swissnex

How will people travel in 20 years? Hyperloop is a proposed mode of transportation which consists of pods transported at high speed through the length of low-pressure tubes. These tubes are elevated off the ground due to a lack of air resistance or friction. The concept of using low-pressure or vacuum tubes as part of a transportation system has a long heritage.

Join the conversation with thought-leaders and experts from Silicon Valley and Europe to learn more about the future of transportation and how these new services will be integrated into the urban mobility landscape. We will discuss this with the Swiss Railways, which bring in expertise in tunnel construction and infrastructure, and with Eurotube, a Swiss Startup developing the infrastructure for hyperloop. During the panel, we will discuss how rail and hyperloop can learn from each other and thrive together. Topics like infrastructure heavy project management as well as innovation in mobility will be covered in the live panel as well.

Getting to a Fusion Pilot Plant - Livestream - 02/09/2021 04:30 PM
Stanford Applied Physics/Physics Colloquium

One hundred years ago Arthur Stanley Eddington conjectured that stars are powered by fusion reactions and speculated that one day humans would generate power by fusion. Not yet.  However, private capital is flooding into fusion research driven by the lure of fusion's promise of sustainable “firm” power and optimism about new technologies. I will discuss the benefits of these technologies including high temperature superconducting magnets, permanent magnets and liquid metal systems. I will also discuss the advances in understanding the physics of confined plasmas and the growing efforts to find optimal fusion configurations. There is increasing confidence that, with these advances, an electricity producing Fusion Pilot Plant could be operational before the middle of the century. The fusion community is calling for a concentrated effort to design such a plant.

The Transformation: A Future History of the World from 02020 to 02050 - Livestream - 02/09/2021 05:00 PM
Long Now Foundation

A compelling case can be made that we are in the early stages of another tech and economic boom in the next 30 years that will help solve our era’s biggest challenges like climate change, and lead to a societal transformation that will be understood as civilizational change by the year 02100.

Peter Leyden has built the case for this extremely positive yet plausible scenario of the period from 02020 to 02050 as a sequel to the Wired cover story and book he co-authored with Long Now cofounder Peter Schwartz 25 years ago called The Long Boom: The Future History of the World 1980 to 2020.

His latest project, The Transformation, is an optimistic analysis on what lies ahead, based on deep interviews with 25 world-class experts looking at new technologies and long-term trends that are largely positive, and could come together in surprisingly synergistic ways.

The problem with plastics (and why microplastics might be toxic) - Livestream - 02/10/2021 11:00 AM
Monterey Bay Aquarium Research Institute

Plastic pollution is a well-known problem, gaining attention in mass media, international organizations, and amongst policymakers. Plastic, however, is not one thing but rather many different materials. The life cycles of plastics are complex - stretching from extraction to production, product development and use, to waste production - involving many actors worldwide. Microplastics, small plastic particles now identified in virtually every niche on the planet, comprise a complex mixture of multiple materials, sizes, shapes, and potentially 1000s of chemicals. What do we know about the hazards associated with microplastics? Do they pose risks in the environment? And importantly, what can we do about this? Bethanie, an ecotoxicologist, will discuss how researchers are working to address these questions. She will also place these issues in a larger context, introducing ideas of using large-scale collective action frameworks to push sustainable development.

Why do dogs trust people? Why do we trust dogs? What forces were at work in the distant past to shape our attitude toward dogs - and their attitude toward us? How can we train dogs to be even more productive companions? What do dogs and human kids have in common? And how can being more “friendly” help humans succeed in today’s world?

Join the Duke dog experts as they address these questions and more, for a live presentation hosted by Smithsonian writer-at-large, Jeff MacGregor, author of our recent cover story about our ancient bond with dogs.

We’ll also save time for you to pose your questions.


Healthy Society Series: COVID-19 Vaccines - What We Know and What We Don't Know - Livestream - 02/10/2021 05:00 PM
Commonwealth Club - Online Event

The COVID-19 pandemic, which began in early 2019, has had significantly negative consequences for individuals, families and communities around the world, with huge economic and political effects. Short-term strategies have involved sheltering in place and social distancing, rigorous and frequent hand washing, and the disciplined use of masks. We now have reached a stage in the pandemic when vaccines are bring rolled out in the United States and globally, initially for “at risk” populations.

There is much confusion arising from conflicting information about the new vaccines. There are questions related to what we know about the vaccines (and how we know it), and what we don’t know (and how and when we will know more). To address these questions, two leading virologists will be in conversation with the chair of the Health and Medicine Forum at The Commonwealth Club of California. Dr. Melanie Ott and Dr. Warner Greene from Gladstone Institutes talk with Dr. Robert Lee Kilpatrick, to help the public understand COVID-19 vaccine options better.

Improving Batteries from the Atoms Up - Livestream - 02/11/2021 05:00 PM
SLAC Public Lecture

In batteries, energy is stored in tiny particles within the electrodes that individually breathe in and out and chemically evolve as the battery is charged and discharged. Improving the efficiency and lifetime of batteries will require a better understanding of how these particles transform individually and how they interact within their own complex ecosystem and with their surrounding environment.  X-rays from SLAC’s synchrotron allow scientists to take photographs of battery materials over a wide range of sizes, down to the size of individual particles and even the size of atoms. In this presentation, I will show photographs of some of these tiny battery components in action. Through this work, we are learning how to redesign batteries from the atoms up.

After Dark Online: Representation Through Visualization - Livestream - 02/11/2021 07:00 PM
ExplOratorium

Technology and design aren’t neutral. But how can we correct course on histories and technologies that have too often left out Black voices, with oppressive results? Tonight at After Dark, we’ll consider this question through two lenses: design history and machine learning.

This program features:

Join graphic designer Silas Munro as he explores Black Design in America, which presents a history of design that centers marginalized designers and cultural figures - particularly BIPOC and QTPOC people - while also considering how design has been used as a tool of oppression. Silas Munro is an educator and the founder of poly-mode, a design studio that uses design to inspire people to better themselves and improve society. 

As technologies driven by machine-learning systems become increasingly widespread, it’s become clear that these systems, often used in surveillance or for decision-making, lack the neutrality they promised. Hear from Deborah Raji about the ways in which machine-learning systems reinforce human bias and racism - and engage with her thoughts on how we can debug” the systems of their discriminatory data and applications. Raji is currently a fellow at Mozilla and was recently celebrated as a key innovator under 35 by MIT Technology Review.


Astronomy on Tap Seattle: Catching Rainbows: How Astronomers can use the Atmosphere to Turn Black and White Images into Color - Livestream - 02/11/2021 07:00 PM
Astronomy on Tap

Groundbreaking new telescopes such as the Vera Rubin Observatory will push our understanding of our solar system and the universe. As we build bigger telescopes with larger mirrors we are able to see fainter objects and create higher resolution images of the night sky, but to extract science from the data we must first solve new challenges. Among those challenges is refraction from our own atmosphere: much as a straw appears to bend when you put it in a water glass, the light from distant stars appears to bend as it passes through the atmosphere to our telescopes. We have long known how to fix this “bending”, but we now must deal with slight differences in that refraction for redder and bluer light, an effect called Differential Chromatic Refraction, or DCR. I will describe the new technique we have developed to correct for DCR, and how we are able to use it to turn black and white images into color.

The event will begin at 7pm and there will be lots of time to ask questions afterwards. We’ll be going live on Zoom and Youtube at 7pm PST! Then join us at 8pm on our Instagram for an Instagram Live Q&A with Dr. Sullivan!

From Junk to Genes: The birth of new miRNA genes in the human genome - Livestream - 02/11/2021 07:30 PM
Bay Area Skeptics

One of the biggest surprises of the genomics era is the discovery that every family, genus, and even species, has a shocking number of unique genes that are not found in closely related species. These so-called “orphan genes” have intrigued scientists for the past two decades and their diverse origins are beginning to come to light. In this presentation, I will present evidence that at least two families of human-unique micro-RNA genes have been created through random genomic rearrangements. These micro-RNAs tweak the expression of hundreds of genes in tissues throughout the body and may have played a role in the unique evolutionary trajectory of our species.

A Most Interesting Problem: What Darwin's Descent of Man Got Right and Wrong about Human Evolution - Livestream - 02/13/2021 11:00 AM
The Leaky Foundation

Join The Leakey Foundation for a free virtual celebration of Darwin’s birthday and the 150th anniversary of the publication of The Descent of Man. This event brings together seven world-class scholars and science communicators to explore what Darwin got right and what he got wrong about the origin, history, and biological variation of humans.

In 1871, Charles Darwin published The Descent of Man, a companion to On The Origin of Species in which he attempted to explain human evolution, a topic he called “the highest and most interesting problem for the naturalist.” This event explores how scientific ideas are tested and how evidence helps structure our narratives about human origins, showing how some of Darwin’s ideas have withstood more than a century of scrutiny while others have not.

This event features six ten-minute presentations with viewer opportunities to submit questions to the scholars. The event concludes with a discussion led by award-winning science journalist Ann Gibbons.
