SciSchmooze Weekly Events Newsletter
Hello again Science fans!

Before we get into the science stuff for this week, a little housekeeping.  We have received occasional feedback that the SciSchmooze appears in a few subscribers' email in a very small font.  We use a default font size (13 pt), but it seems various email processors think they know better and mess around with sizes.  Before mailing this out each week, we test-send the Schmooze to ourselves, and it always looks fine, although my phone does ignore the default font size we use. So this week I'm attempting to get around all that by sending the Schmooze in a larger font (it isn't as easy it it might seem).  Let's see if that is better.

For the first time in 19 years, a blue moon will fall on Halloween.  You all know the saying "once in a blue moon" which describes the fact that having two full moons in a month is fairly rare.  The last time Halloween and a blue moon coincided was in 2001.  Before that...1955!  There will be six in the 21st century, and two of them have already happened (including the upcoming one).  Rare indeed!

There's lots more news in astronomy/cosmology.  Last month I mentioned that Osiris-Rex was about to attempt to obtain samples from the asteroid Bennu.  It was successful...too successful!  Think for a minute just what was involved in this mission.  First, launch the spacecraft, which is about the size of a minivan, and have it intercept Bennu.  Now get it to go into orbit.  Since Bennu is really small, it has almost no gravity, so achieving a close orbit wasn't simple.  Now take lots of pictures of the asteroid to help determine a safe place from which to take the sample.  Then maneuver the spacecraft to gently touch the surface of Bennu, capture some of the asteroid's material, and retreat.  Still to come is the stowing of the sample into a capsule, returning to Earth, and sending the capsule back to us on the surface.

Meanwhile, way out around Jupiter, Astronomers have observed the volcanic activity on the moon Io for the first time.

The light we see from distant galaxies began its journey to us a long time ago.  For the oldest galaxies, we're talking 13.7 billion light years.  Earlier this month, astronomers announced the discovery of a giant black hole surrounded by a litter of young protogalaxies that dates back to the beginning of time.  The distance to such phenomenon can be calculated because we know the speed of light, which is faster than anything else.  Except when it isn't.

From such grand scales to the smallest.  Scientists have now clocked the shortest time measurement ever, 247 zeptoseconds! That's 1 trillionth of a billionth of a second.

The Hubble Space Telescope celebrates 30 years of discovery.  This week Dr. Dan Wilkins of Stanford University, gave a talk about the Hubble, how long it took to make it a reality, the problems with it once launched, how they were fixed, and the discoveries it has made since then.  This talk is fairly high level and I highly recommend you spend an hour watching it.

Here's a reminder of just how interconnected things are.  For the first time in recorded history, the Laptev Sea has not yet frozen over by this time of year.  "So what?" you ask?  This isn't just some water that's late freezing over, but the start of a complex cycle of environmental activities that are messed up now.

A couple of years ago I was in Kansas City for a few days while on a train trip.  I wandered into KC's train station where the public spaces were filled with exhibits from student science fair projects.  I was surprised by the complexity of many of the things these students were researching for their projects and spent several hours wandering around looking at the projects.  A 14 year old girl has won a $25,000 prize in a science competition for finding a potential cure for COVID-19!  Wouldn't it be something if it turns out an eighth grader found the key to overcoming this virus?

Lastly, a reminder to vote!

Have a great week in Science!

Flip the Switch: Controlling the Spin Crossover Transition in an Fe2+ Organic Molecule Thin Film Through Interface Engineering - Livestream - 10/26/2020 02:30 PM
UC Berkeley,

The physics of organic molecule thin films has opened up the field of molecular spintronics research. Organic molecules are coveted as the active ingredients for novel spintronic and electronic devices due to their versatility and energy efficiency, but also for their inexpensive ingredients and much reduced processing cost compared to conventional circuitry. Bi-stable spin-crossover molecules are promising candidates for memory and logic devices, while at the same time a number of fascinating fundamental questions regarding their switching mechanism remain to be explored.

In Fe2+ spin crossover systems, an Fe ion surrounded by a cage of ligands similar to the metal in tetrahedral configuration, that can be found in many complex oxides. The metal can assume two distinct spin states: the low spin state with fully occupied tg states and empty eg states (S=0µB), and the high spin state partially occupied tg states and partially occupied eg states (S=4µB).

Here we present a number of ways to change the energetics of the transition between the spin states, primarily by choosing and manipulating the interface of a molecular thin film with its support. As enabling probe in this work is x-ray absorption spectroscopy, which can directly probe the occupancy of the t2g and eg states of iron. In addition to interface engineering, we show the influence of an electric and magnetic field on the sp in-crossover transition and lay out a path to spin-crossover molecule based devices.

From Earth to ET: the use of synthetic biology for NASA’s missions - Livestream - 10/26/2020 03:30 PM
SLAC Colloquium,

Synthetic biology - the design and construction of new biological parts and systems and the redesign of existing ones for useful purposes - is transforming fields from fuels to pharmaceuticals and beyond. Our lab has pioneered the potential of synthetic biology to revolutionize two areas of interest to NASA: astrobiology and as an enabling tool for exploration. Synthetic biology is allowing us to answer whether the evolutionary narrative that has played out on planet Earth is likely to have been unique or universal. For example, in our lab we have re-evolved the biosynthetic pathways of amino acids in order to understand potential capabilities of an early organism with a limited repertoire of amino acids. And what about the limits for life? Can we create organisms that expand the envelope for life, for example, radiation resistance? For exploration, we will rely increasingly on biologically-provided life support, as we have throughout our evolutionary history. But once life itself is seen as an enabling technology, we can do so much more. What about the exploration platforms themselves? Metal recovery? Building materials? BioWires? Will this technology work in space? The PowerCell payload on the DLR EuCROPIS mission is designed to do just that. Activated in December 2018, early results will be presented.

Proton and nuclear structure from the Standard Model - Livestream - 10/26/2020 04:15 PM
UC Berkeley,

Our understanding of the structure of matter, encapsulated in the Standard Model of particle physics, is that protons, neutrons, and nuclei emerge dynamically from the interactions of underlying quark and gluon degrees of freedom. I will describe how first-principles theory calculations have given us new insights into this structure, including recent predictions of the contributions of gluons to the pressure and shear distributions in the proton, which will be measurable for the first time at the planned Electron-Ion Collider.

I will also discuss studies of light nuclei which provide insights relevant to long-baseline neutrino experiments seeking to constrain the neutrino masses and mixing parameters, searches for evidence of the Majorana nature of neutrinos through neutrinoless double beta decay, and dark matter direct detection experiments. Finally, I will explain how provably exact machine learning algorithms are providing new possibilities in this field.

Drivers of hot and cold past wet states recorded by lakes in the western United States - Livestream - 10/27/2020 03:30 PM
UC Santa Cruz,

G.K. Gilbert’s 1890 monograph on Lake Bonneville published by the United States Geological Survey initiated over a century of research on Quaternary lakes in the American west. The continuation of this work is increasingly pertinent today with the need to test climate models used to forecast future water resources in the region as the climate warms. Importantly the presence or absence of lakes in terminal basins provide an unequivocal measure of wetness. In this work I will show that wetter conditions during both colder- and warmer-than-present periods in the past are recorded in shoreline and outcrop data from the latest Pleistocene and the middle-Pliocene. In conjunction with paleotemperature data, derived from pollen, macrofossil assemblages and carbonate clumped isotope measurements, I will show scaling relationships implying that: 1) Pleistocene lakes during glacial maxima in the northern Great Basin do not require substantial precipitation increases to explain lake shoreline extents; and 2) middle-Pliocene lakes would have required up to a doubling of precipitation in the southwest. These inferences provide quantitative targets for assessing the performance of climate model simulations of the terrestrial water cycle. In addition, I will show ongoing work associated with the application of carbonate clumped isotope thermometry and triple oxygen isotope measurement to lacustrine lake sediments in the western United States.

Blockchain for the Public Good- Livestream - 10/28/2020 12:00 PM
Citris Research Exchange,

Blockchain technology has gained notoriety over the past decade as a platform for cryptocurrency such as Bitcoin, which has been used for illicit exchange of weapons and drugs, as well as paying off hackers whose ransomware holds computer systems hostage. At the same time, researchers and developers have been exploring the use of blockchain and the broader domain of distributed ledger technology for more beneficial applications, such as in healthcare, education, property title, and public finance.

California lawmakers commissioned a task force in 2019 to study the potential of blockchain for public sector applications by creating the Blockchain Working Group. The 20-member group, including those speaking today, comprised experts in computer science, cybersecurity, information technology, law, and policy. We were charged with drafting a working definition of blockchain, providing advice to State offices and agencies considering blockchain platforms, and offering guidance to policymakers to foster an open an d equitable regulatory environment for the technology in California.

This talk will draw on the panelists' expertise in the fundamental computer science and security concerns of blockchain, its applications for public finance, and ethical considerations of its development. We will also discuss the experience of working with a broad group of stakeholders to create a roadmap for policymakers, CIOs and other leaders considering blockchain solutions for public sector applications.

Collaborative marine monitoring and coastal habitat restoration within an indigenous co-management context in Gwaii Haanas, Canada - Livestream - 10/28/2020 03:30 PM
Estuary & Ocean Science Center,

Dynamic, complex and interwoven marine systems on Haida Gwaii evolve with changing ecological and social-cultural conditions. Today, the Haida Nation and Canada cooperatively manage Gwaii Haanas National Park Reserve, National Marine Conservation Area Reserve and Haida Heritage Site. To remain sustainable and maximize value, our tiered marine monitoring program collaborates with management partners, other government institutions, non-government organizations and academia, and is linked with monitoring programs for Haida Gwaii, BC, and other national Parks. Through Chiixuu tll iinasdll Nurturing Seafood to Grow, we collaborate with fishing industry and academia to restore kelp forests diminished by sea otter extirpation, and understand ecological implications of kelp forest recovery. Kelp forests today are also challenged by warming oceans linked to lower kelp productivity, sea star wasting disease, and urchin-grazing. At this time of rapid environmental change, tightly-coupled interconnections at multiple scales in marine social-ecological systems calls for adaptive and collaborative programs that span knowledge systems to inform conservation actions.

Mitigate, Adapt - or Suffer: Connecting Global Change to Local Impacts - Livestream - 10/28/2020 04:00 PM

Climate is changing - throughout California, across the United States, and for the planet as a whole. Temperatures are increasing, rainfall patterns are shifting, and extreme precipitation and heat wave events are becoming more frequent. Climate change isn’t just a problem for polar bears or future generations anymore - it’s affecting us, here and now. Not only that, but the choices we make today will have profound impacts on our future: the faster we cut our carbon emissions, the less we’ll need to adapt and the more suffering we can avert. In such a politically charged environment, are we still able to act on climate? Or is it too late? Join Katharine Hayhoe as she untangles the complex science connecting our choices to future impacts and highlights the actions that are being taken to combat this critical issue today.

To eat or not to eat: is that the (only) question? - Livestream - 10/28/2020 07:00 PM
Science on Tap,

A key challenge of the modern world relates to how our contribution to environmental degradation has a pervasive effect on our own health and the health of future generations. There is evidence from human epidemiological studies and animal models demonstrating that exposure to environmental agents prior to conception or during early development can increase disease susceptibility later in life. We and others showed that developmental exposure to different environmental toxicants leads to metabolic alterations, such as obesity or type 2 diabetes, not only in the first generation but also in future generations. Therefore, it is likely that the ramping rates of metabolic diseases worldwide have a significant component associated with current and ancestral exposures to environmental toxicants. In this talk, we will discuss more details about our current understanding of the mechanisms underlying multi-generational effects after exposure to environmental agents in the context of human disease.<p.

Towards Safe Drinking Water for All - Livestream - 10/29/2020 10:00 AM
Energy and Resources Group,

Safe water, sanitation and hygiene are essential to safeguard health and save lives in low-income countries. The last several decades have seen many innovations in the development of low-cost and efficacious safe water technologies, most of which have been household-level treatments. In general, low-income households have not adopted such technologies at scale. In this talk Prof. Ray argues that public health researchers (including herself) have had too simplistic an understanding of poverty. They have not rooted their work in insights into the lived experience of poverty, with its uncertainties, stresses from constant scarcity, and attendant fears. Such insights are central to understanding why technologies for safe water remain unused by so many households who could benefit from them. Rather than improved versions of household-scale delivery models, transformative investments in safe water “for all” require utility-scale services. Until then, research should focus only on interim safe water options that are on the pathway towards the utility model .

After Dark Online: OK With Decay - Cemetery of Dead Science - Livestream - 10/29/2020 07:00 PM

Here lie deceased explanations
Done in by controlled exploration.
These theories, once bold,
Can now be retold
Without fearing their reincarnation.
 - co-written by Craig Anderson, Kevin Boyd, Hugh McDonald, and Megan Pruiett

On the eve of the eve of All-Hallow’s Eve, we bring one of our favorite annual events, the Cemetery of Dead Science, online. While we look to science as a trusted source for understanding the world around us, knowledge is ever-evolving. Tonight, we’ll look at debunked science from pasts both distanced and recent. We’ll also dig into the scientific process to better understand how questionable concepts can gain legitimacy.

This month’s After Dark Online is a get-together to fall apart. As autumn sets in, trees become bare, and the northern hemisphere begins to chill, we’re exploring processes of decay, entropy, and how things come apart, making way for revisions and new arrangements.

Imaging fluid-rich faults and melt-rich asthenosphere with electromagnetic data: Examples from the Hikurangi and Middle America subduction - Livestream - 10/30/2020 12:00 PM
institute of Geophysics and Planetary Physics,

Fluids and partial melts are critical factors in several plate tectonic processes. In this presentation, I will briefly review the utility of electromagnetic (EM) methods and discuss two research applications: (1) what the distribution of fluids tell us about shallow plate coupling and slip behavior at subduction zones, a nd (2) on the origin of the lithosphere-asthenosphere boundary (LAB). The first application will feature results from marine EM surveys at the Central America subduction margin offshore Nicaragua and the Hikurangi subduction margin offshore North Island, New Zealand. For the second application, I will show the synthesis of several geophysical and geochemical data sets from the Cocos plate - including work done in the region by UCSC researchers Brian Dreyer, Andy Fisher, and Eli Silver - to explain the origin of a partial melt channel previously inferred at the LAB.

Watering the Land from Below: Groundwater Influence on the Terrestrial Environment - Livestream - 11/03/2020 03:30 PM
UC Santa Cruz,

Much of the water on land is groundwater, which moves through the Earth’s crust at time scales of days near the surface to billions of years kilometers down. I will focus on the shallow and actively circulating groundwater which facilitates many near-surface processes that directly influence water, energy and biogeochemical cycles on Earth. I will examine the modern-day patterns and drivers of continental water storage and drainage, and their influence on land plants such as plant rooting depths and seasonal plant water sources. Then I will pose some hypotheses on how the shallow groundwater may have functioned through the geologic past, with the last deglaciation and land plant evolution as two examples.
