Mars! And a new look for the SciSchmooze

SciSchmooze 2/28/2021

Hello again Science Fans!

This week marks a new look to the Schmooze. We’ve switched to a new mailing system and with that comes a new format. We hope you find it easier to read. We can easily include images, but our content won’t be changing. We welcome your feedback.

There’s big news from space. Perseverance landed safely on Mars and began sending pictures back of the landing site. Depending on how you count, there are 25 different cameras deployed with this landing. They see different spectra. Here’s an article about the technology and variety and what we can expect to see going forward.

Of course, Perseverance isn’t the first rover to land on Mars. There are some stunning pictures returned from Curiosity and Opportunity and Elderfox Studios has turned some of them into two 4K short movies that are worth watching. NASA has over 6,000 pictures (and counting) available for you to see from Perseverance. Here are some highlights.

There’s also big news on the COVID-19 front. The Johnson and Johnson vaccine has received emergency authorization, meaning it can now be given to the public. This greatly increases the number of doses of vaccine available in the US. This vaccine is different from the Moderna and Pfizer vaccines, however. Here’s how it differs.

If you have questions about the vaccines, here are some answers. A lot is being done to educate the public, including efforts through community and world leaders. It wasn’t that long ago that most people I knew didn’t know anyone who had been infected by COVID, let alone anyone who had been vaccinated. That sure has changed as I know many people who have either had it themselves, or have relatives who have suffered. And I know two other people, besides myself, getting their second shots just this coming Tuesday alone! Roughly half of those 65 and older in the US have received at least their first dose.

With the Johnson and Johnson vaccine coming online this week, more than 100,000,000 people could be vaccinated by the end of March. More than 8% of the US population has contracted COVID since the start of the pandemic a year ago. Worldwide, almost a dozen different vaccines are being given. Russia, China, and India each have vaccines developed within their countries, but not generally available outside their borders.

(Editor’s note: One of our readers pointed out that his relatives, who live in different parts of South America, have been receiving the Russian and Chinese vaccines, so those two at least are available in certain countries outside their country of origin. The source of my information was apparently incorrect.)

The new infection rate has dropped to a level not seen since the fall, although that trajectory has reversed in the past few days. San Francisco and San Mateo counties have dropped into the red tier, and Santa Clara is poised to drop this week.

Most things in science start with a question. A theory is developed, and experiments created to test that theory. Often the results are unexpected. Sometimes, those unexpected results provide revolutionary improvements to life that weren’t part of the original question. Take this 1960’s example that made today’s COVID tests possible. Then there’s the recent discovery of marine life 3,000 feet below the Antarctic ice shelf, also an accidental discovery.

While temperatures have warmed back up and the power is back on to much of Texas, the mid-month winter storm really highlighted some weakness in that state. By now you’ve probably read about the false claims that renewable energy sources are to blame for the problems.

Rounding out the odds-and-ends department…Levitation is real! And background “noise” in our brains may not actually be noise, but information.

My picks this week include:

The bright future of cosmology with SPT-3G - Livestream - 03/01/2021 11:00 AM
SLAC Special Seminar

Observations of the cosmic microwave background (CMB) probe a diverse set of fundamental physics in both the early and late universe.  CMB measurements are a cornerstone of our now exceptionally precise Lambda-CDM model of cosmology, however, many questions remain.  Did an inflationary epoch occur a fraction of a second after the Big Bang?  What is the nature of dark energy?  Is the Hubble constant controversy new physics or simply measurement systematics?  I will describe the SPT-3G receiver that is currently installed on the South Pole Telescope and how it is observing the CMB to answer these questions.  Now starting the third year of a five-year survey, SPT-3G data is already providing tantalizing hints about what scientific goalposts will be possible in the very near future.  I'll highlight a few of these opportunities as well as providing perspectives on the upcoming CMB-S4 experiment.

Probing emergent order in quantum materials by cryogenic electron microscopy - Livestream - 03/01/2021 02:30 PM
UC Berkeley

In quantum materials strong interactions between the electrons and the atomic lattice can give rise to novel electronic states with properties not achievable in conventional materials. These states often compete with other correlated states of spin, charge and the atomic lattice. One example is charge ordering, in which electrons as well as the atomic lattice form periodic patterns that not only lift the symmetries of the crystal but also underlie exotic electronic phenomena such as superconductivity, metal-insulator transitions and colossal magnetoresistance. Understanding the microscopic nature of electron-lattice interactions at the relevant length scales at which quantum phenomena arise, and the role of disorder requires advanced spatially resolved probes.

In this talk, I will discuss our advances in scanning transmission electron microscopy (STEM) to probe emergent order in quantum materials at the atomic scale. First, I will discuss our results on a class of superconducting materials, the recently reported infinite-layer nickelates, with particular focus on the microscopic structure, strain and the role of defects in these thin film superconductors. Going beyond room temperature STEM, cryogenic sample cooling promises direct access to low temperature phases and quantum phase transitions. These new capabilities have paved a path to visualize subtle lattice and electronic orders in emergent low temperature phases as I will show in the second part of the talk. Focus will be on the lattice behavior of charge-ordered manganites, where direct imaging can discriminate between multiple structure models, and mapping over larger length scales shows phase coexistence and nanoscale inhomogenities.

Looking inside the heart of a supernova from underground - Livestream - 03/01/2021 03:30 PM
SLAC Colloquium

Core-collapse supernovae host some of the most extreme physical environments in our universe. They play a fundamental role in shaping the world around us, from seeding new star formation to spreading heavy elements around the Galaxy. The extreme physical conditions make them very valuable laboratories for particle physics, nuclear physics and astrophysics. In this talk, I will review the basic mechanism driving these gravity-powered neutrino bombs and then discuss examples of the rich physics that is imprinted on the expected neutrino signal. The DUNE experiment currently under development in the US will provide unique capabilities for observing physical processes in and around the collapsed core.

Hydrogen's role in achieving net-zero carbon emissions for the global economy - Livestream - 03/01/2021 04:00 PM
Stanford Energy Seminar

While electricity will assume a dominant role in conveyance of clean energy to end users, sectors such as heavy-duty trucking and transport, marine, aviation, and heavy industry are more difficult to decarbonize, and will benefit from the higher energy density and storage afforded by hydrogen as a vector.   Hydrogen can also be used to synthesize other molecular energy carriers and chemicals for recycle of carbon to achieve circularity.  This seminar will examine the challenges and multiple synergistic opportunities for hydrogen in future energy and chemical systems.     Is now the time for a hydrogen economy?

How neural circuits are wired up during development to perform computations - Livestream - 03/01/2021 04:15 PM
UC Berkeley

How are neural circuits wired up during development to perform specific computations? We address this question in the retina, which comprises multiple circuits that encode different features of the visual scene.  These features are encoded in the neural activity of the activity of roughly 40 different types of retinal ganglion cells, the output cells of the retina that transit this information to the brain. We will explore the example of direction-selective ganglion cells, which respond strongly to an image moving in the preferred direction and weakly to an image moving in the opposite, or null, direction. This asymmetric computations is mediated by neurons that are symmetric in their shape but asymmetric in their connectivity,  I will present recent progress in the lab in characterizing how this asymmetric wiring emerges during development and the role that activity plays in establishing mature circuits.

When Words Aren’t Enough: The Visual Climate Story - Livestream - 03/02/2021 12:00 PM
Commonwealth Club - Online Event

While IPCC risk assessments and emission projections can help us understand climate change, they don’t exactly inspire the imagination or provoke a personal response to the crisis. The solution? A growing league of storytellers who use photographs, films and the human experience to breathe life into the cerebral science of anthropogenic climate change. Images can tap into our senses and break down barriers that statistics cannot - how far can they go to inspire a global climate response?

Join us for a conversation on the art of visualizing climate change with filmmaker Céline Cousteau, producer and director Davis Guggenheim, and photographer Cristina Mittermeier. Greg Dalton, Moderator

Lubricants and Glitter: Revolutionizing Sexual Assault Investigation @ Online Zoom Event - Livestream - 03/02/2021 05:00 PM
California Section American Chemical Society

Sexual assaults are an unfortunate reality in modern society, which includes situations in which the assailant is known or unknown. While DNA is the go-to forensic evidence in sexual assault cases, the reality is that the use of condoms in sexual assault is increasing in an effort to minimize the type of DNA left at the crime scene, specifically sperm/semen. Therefore, in the absence of DNA, it is necessary to identify other type of forensic evidence (such as lubricants and cosmetic residues) that could be used in these types of cases to link the three points in the criminal triangle, e.g. victim, suspect and crime scene. This talk will discuss current efforts that we are conducting to understand the evidentiary value of lubricant and cosmetic evidence and appropriate analytical methods to analyze and characterize unknown samples collected in a sexual assault or physical assault cases.

Wonderfest: Prescribed Burns and Exploding Stars - Livestream - 03/02/2021 08:00 PM
Wonderfest

Stanford evironmental scientist Rebecca Miller on "Prescribed Burns in California" - Over the past several years, California has experienced record-breaking wildfire seasons. Recent wildfires have prompted important policy conversations about prescribed burns, fires that are purposefully set to remove ground vegetation and reduce fire risks. What are the challenges that have prevented us from using prescribed burns in California, and how might we wisely expand the use of this valuable fuel treatment?UC Berkeley astrophysicist Kishore Patra on "Exploding Stars" - The atoms in everything around us - the oxygen in the air, the carbon in our bodies, the gold in our jewelry - were forged in stellar furnaces. We owe our very existence to stars that died in cataclysmic explosions known as supernovae. What is the cosmic story of our elemental origins? What do we know about supernovae, and how do astronomers study them?

Decarbonizing the Grid - The Role of Grid Interconnection - Livestream - 03/03/2021 08:30 AM
Stanford Energy

Robust long-distance transmission lines (both HVAC and HVDC) will enable delivering clean energy to customers and expanding the ways that clean energy is used. Interregional planning and coordination are usually difficult in the U.S. due to different planning approaches, models, FERC 1000 processes, and market rules among the various RTO/ISOs. On a global scale, international grid interconnection projects are being proposed and developed very actively for efficient and economic use of clean energy.This is the second virtual panel in a series of workshops. It will focus on the role of grid interconnection for decarbonization. Panelists will discuss interregional (international) transmission expansion plan, planning process, as well as social, economic, and geopolitical aspects of large transmission projects.

Dr. Euan Ashley: The Genome Odyssey - Livestream - 03/03/2021 10:00 AM
Commonwealth Club - Online Event

Thanks to developments in genetic medicine, for the first time we have the ability to predict our genetic future, to diagnose and prevent disease before it begins, and to decode what it really means to be human. Since the Human Genome Project was completed in 2003, the possibilities for genetic medicine have only grown. But what does the human genome and genome sequencing mean for citizens today, and what will it mean for health care over the next several decades?

In his new book, The Genome Odyssey, Dr. Euan Ashley answers some of the questions by detailing the medicine and science behind genome sequencing, introducing a dynamic group of researchers and medical investigators who hunt for genetic answers, and bringing forward pioneering patients who open up their lives to the medical community during their search for diagnoses and cures for inherited diseases. Ashley describes how he led the team that was the first to analyze and interpret a complete human genome, how they broke genome speed records to diagnose and treat a newborn baby girl whose heart stopped five times on the first day of her life, and how they found a boy with tumors growing inside his heart and traced the cause to a missing piece of his genome.

Dr. Ashley and his team, and a small number of others around the country, are currently working to expand the boundaries of our medical capabilities and to envision a future where genome sequencing is available for all, and where medicine can be tailored to treat specific diseases before they show symptoms and to decode pathogens like viruses at the genomic level.

Please join us as Dr. Euan Ashley talks about revolutionizing health care and the future of medicine by continuing to unlock the secrets of the human genome.

A Deep Dive with Ocean Explorer David Gallo - Livestream - 03/03/2021 01:00 PM
Science and Entertainment Exchange

Hear from renowned ocean explorer David Gallo, co-leader of the TITANIC and missing flight Air France 447 expeditions.

Our oceans have long been a source of scientific investigation and play a fundamental part in supporting life on Earth. They represent the planet’s largest habitat and are home to more than half of its species. They regulate our climate and are key actors in the carbon cycle. In many ways, they are also our final frontier, holding fast to secrets that lie deep beneath the surface. But we’re discovering new and surprising ways that the oceans are important to us. And we’re gradually coaxing them into yielding answers with which they’ve been stingy for decades. Acclaimed oceanographer and marine explorer David Gallo brings us new evidence documenting the critical part that the oceans play in maintaining life on earth. He also reveals plans for future long-distance expeditions - including an attempt to locate Ernest Shackleton’s long-lost ship ENDURANCE.

From communities to ecosystems: linking ecological responses to multiple global change drivers - Livestream - 03/03/2021 03:30 PM
Estuary & Ocean Science Center

Global change is altering resource availability, which in turn is predicted to change the composition and functioning of communities. Here, I synthesize plant and ecosystem responses to resource manipulations from over 100+ global change experiments in the CoRRE (Community Responses to Resource Experiments) database. First, we show that community composition changes are greater than changes in richness alone. Next, we explore methods to study community compositional changes based on rank-abundance curves. We show that plant communities are changing in dynamic ways, with no one best measure to study these changes. The synthesis demonstrates the need to take a wholistic approach to studying community changes. Finally, I explore how ecosystem production is affected by resource experiments through changes in community composition.

Searches for New Physics at the Edge of Absolute Zero - Livestream - 03/04/2021 12:30 PM
SLAC Special Seminar

Why is there something in the universe instead of nothing?What is the nature of the dark matter that constitutes ∼85% of the matter content of the universe?

Each of these two questions brings together physics on the largest of observable scales with the behavior of particles on the smallest of scales. Why matter formed and what caused it to cluster into galaxies and stars are among the most fundamental open questions in physics today. And the answers may lie in understanding the breakdowns of the Standard Model. In this talk, I will discuss the search for Neutrinoless Double Beta Decay, a lepton number violating decay that could help explain the matter dominance of the universe. I will describe the CUORE experiment, a tonscale bolometeric detector that searches for this and other rare decays, and the R&D on multiplexed TES sensors that could be instrumental in a next-generation experiment. I will then discuss the axion and its reemergence as a leading dark matter candidate. I will describe the ABRACADABRA-10 cm demonstrator experiment at MIT and present results from its recent searches for axion dark matter. Finally, I will describe the DMRadio program - a joining of ABRACADABRA-10 cm with the DMRadio-Pathfinder program at SLAC - and its prospects of probing some of the most interesting axion dark matter parameter space as a full-fledged, next-generation dark matter experiment.

Earth-Observing Satellite Boom and Emerging Hazards in the Era of Climate Change - Livestream - 03/05/2021 12:00 PM
UC Santa Cruz

With the global population surpassing 7.8 billion people in 2021, the impacts of human activities on the environment are noticeable almost everywhere on our planet. The consequences of these impacts are still elusive, particularly when trying to quantify them at larger scales. It is essential to trace environmental changes from a local to a global scale over several decades. This task is increasingly fulfilled by Earth-observing (EO) satellites, in particular, radar imaging instruments. Synthetic Aperture Radar (SAR), a cloud-penetrant microwave imaging system, provides unique day-night and all-weather monitoring capabilities. The availability of repeated SAR acquisitions with similar imaging geometry allows performing interferometric SAR (InSAR) processing. InSAR uses radar to illuminate an area of the Earth's surface and measures the change in distance between satellite and ground surface, as well as the returned signal strength. Such measurements are suitable for generating high-resolution digital elevation models and accurate terrain deformation maps. Here, I discuss some of the recent advances in developing modern multitemporal InSAR algorithms. Next, I present examples demonstrating the value of high-resolution Radar EO satellite data for mapping surface deformation with implications for sea-level rise, coastal flooding hazards, and quantifying droughts' impact on groundwater resources. Firstly, I report on high-resolution vertical land motion measurements along the U.S. coast obtained from InSAR, spanning 2003-2020. The findings include subsidence rates of up to several millimeters per year affecting different parts of the U.S. West and Gulf coasts, particularly deltas, wetlands, artificial landfills, and Holocene mud deposits. For instance, a subsidence rate of 2-10 mm/yr affects most coastal areas along San Francisco Bay. Furthermore, it is estimated that between 4.3-8.7 million people in California's coastal communities are exposed to subsidence. In combination with future projections of sea-level rise under different climate warming scenarios, it is estimated that in San Francisco Bay and Houston, an area of 125 km2-429 km2 and 186 km2-1157 km2, respectively, will be subject to inundation and flooding by 2100. Secondly, I present results from an interdisciplinary study of the response of aquifer systems in California's Central Valley to the drought periods of 2007-2010 and 2012-2015. The findings show that during droughts, the land subsidence modulated with a seasonal variation independent of the winter precipitation. The subsidence continues beyond the drought periods, although the groundwater levels have already stopped declining. It is estimated that maximum subsidence rates in the southern San Joaquin Valley are up to ~25 cm/yr and ~35 cm/yr for the 1st and 2nd droughts, respectively. Also, the groundwater loss of 21.3±7.2 km3 for the entire Central Valley during 2007-2010 and 29.3±8.7 km3 for the San Joaquin Valley during 2012-2015 is obtained. The subsidence-based estimates of groundwater loss are consistent with that of GRACE gravimetric satellites, considering uncertainty ranges. It is also found that due to overdraft, the aquifer system storage capacity was permanently reduced by up to 5%. These sets of case studies highlight the importance of EO satellite data for developing management, adaptation, and resilience plans.

TEDXBERKELEY 2021: IMAGINE IF... - Livestream - 03/06/2021 11:00 AM
TEDxBerkeley

If all the clouds in the sky melted into cotton candy, would they taste blue or pink?

As kids, questions like this came as naturally as breathing. With our imagination flowing freely, nothing was impossible. Imagination is a quality so deeply ingrained in human nature that we almost take it for granted. Yet, it also inspires incredible change.

Imagine if we had quantum computing, we lived in a prejudice-free society, we eliminated carbon emissions...

This year, at TEDxBerkeley 2021: Imagine If…, we invite you to explore how imagination has shaped history and offers limitless possibilities for the future. It will take our collective imagination to solve the world’s greatest challenges, from technology to climate change and medicine to human rights. Together, let’s champion creativity and consider the impossible.

Growing Supermassive Black Holes - Livestream - 03/08/2021 11:00 AM
Royal Observatory, Edinburgh

We now know that supermassive black holes, with masses of millions to billions of times the mass of the Sun, are found at the centres of most galaxies (including our own galaxy, the Milky Way). But where do they come from and how do they get so big? This talk will describe how astronomers are able to see growing black holes and why we think they play a key role in shaping the Universe.

Gamma-ray Bursts: Nature’s Most Remarkable Cosmic Explosions - Livestream - 03/08/2021 03:30 PM
SLAC Colloquium

First discovered serendipitously in 1967, the phenomena known as gamma-ray bursts - short-lived, extremely bright flashes of high-energy radiation - mystified astronomers for decades. Despite many breakthroughs, key open questions - such as the mechanism responsible for the prompt gamma-ray emission, as well as a detailed characterization of their progenitor systems - remain open. In this talk I’ll review several recent results, including 1) the discovery of very high-energy (TeV) gamma-rays from ground-based Cherenkov detectors; 2) the association of a peculiar short gamma-ray burst with the binary neutron star merger GW170817; and 3) prospects for utilizing these events as probes of the early universe and the epoch of reionization.

A fireside chat with two pioneers in science, Sandra M. Faber and Kathryn D. Sullivan - Livestream - 03/08/2021 05:30 PM
UC Santa Cruz

We are thrilled to invite you to an inspiring conversation with two of our most prominent trailblazers in science, and who we are proud to say will be distinctly honored in our transformed Science & Engineering Library.

The conversation will explore their incredible careers and the influence UC Santa Cruz has had on their unparalleled success. Among many of their accomplishments, for instance, Sandra co-led the largest project in the history of the Hubble Space Telescope, an undertaking that extended our view of galaxy formation back nearly to the Big Bang, while Kathryn was part of the team that launched, rescued, repaired, and maintained the Hubble Space Telescope. The list of their accomplishments, recognitions, and awards is unmatched. What inspired them to pursue these exceptional careers? What is next for them? What are their hopes for our current students?

Speakers: Sandra Faber, UC Santa Cruz emerita; Kathryn Sullivan, Astronaut; Beth Shapiro, UC Santa Cruz, Moderator
