Traffic watch with the SciSchmooze

Science Schmooze 5.17.21

Hi Science Fans,

So much to consider yet so little time. How often have you thought of something similar to that? Let’s hold off on a lot of covid topics this week and just say that things are changing all the time and people are probably disagreeing just as much. It isn’t going to happen for a long time but I have to admit that the idea of a traffic jam on Mars is entertaining. Curiosity, Perseverance, and Zhurong are all on the surface checking things out and doing scientific research. I doubt that Ingenuity will require an Extraterrestrial Control Tower any time soon! There’s a lot of equipment around Mars as well. The latest to join the dance is Hope a project from the UAE.

Back to covid for a moment… The explOratorium is going to be opening on July 1! Aside from the success of the vaccines it is some of the best news I have heard in a long while. Also in the opening news for local science museums is Chabot Space and Science Center. They are making big changes that are taking a bit longer. Watch for them too.

It seems that a refresher as to what critical thinking is might be worthwhile. Of course a lot of people could use a good orientation to it as well. One important thing to understand is that while many of us think we are good at critical thinking, that doesn’t mean that two skilled critical thinkers will actually agree. The accuracy or “truthiness” of what people accept varies in many ways, and due to the tendency or orientation of what is accepted, agreement is still not assured. So, do you think you are a critical thinker? The importance of understanding context, facts, intent, and source are critical. An interesting column popped up in the SF Chronicle this morning. What do you know about Fun Vax? Today it is really difficult to tell if some citation or resource is accurate and trustworthy. Most people know about and use the excellent Snopes but there are many others that are worth using. Here’s a good list that covers a lot of resources and also how to evaluate information that you come across. You can also do a lot on your own to check things out.

As always there is a lot available for learning this coming week. Here are a few to check out…

The Science of Color and Modern Human Perception Tue @ 5:00

Full-Spectrum Science Online: Big & Small Wed @ 4:00 Catch this one. Ron Hipschman is one of the explO folks that is being laid off, just before he hits 50 years at the explO!

Wild & Scenic Film Festiva Fri @ 7:00

Some hopeful news but possibly not good news from Earthweek this week. The Western Monarch Butterfly may not be disappearing/going extinct but just adjusting to climate change. The fight over nuclear power isn’t getting any simpler. Chernobyl is literally heating up again and Fukushima Daiichi is going to be releasing more than one million tonnes of contaminated water.

One of the fun things to do around sunrise or sunset is look for the International Space Station. Here are current times for San Francisco. Actually, if you know where to look there are a lot of things “up there”. On view this week sometimes even with binoculars or your eyes. Here’s another site that you can spend a lot of time at… The Royal Institution, they really know how to celebrate!

Do you feel like getting out and checking out the California coast and ocean? You might want to enter the California Ocean and Coastal Amateur Photography Contest

I hope you have a great week learning new things and enjoying a bit more maskless time!

Capitalism's Last Frontier: Entrepreneurship on the Navajo Nation - Livestream - 05/17/2021 03:30 PM
SLAC Colloquium

Nearly one century ago, the Navajo Nation government was created in response to the discovery of major oil reserves on Navajoland, a 28,000 square mile landmass that spans Arizona, New Mexico, and Utah. The newly founded government accepted agreements with multinational companies in the hopes of bringing jobs and economic opportunities to the community. Over the decades, it has become clear these agreements and the policies supporting extractive industries have caused irreparable harm to cultural practices, damaged the Colorado Plateau's air, water, and land, and hindered tribal members living on reservation land from developing businesses that support the local economic base. Drive through any community on the Navajo and Hopi nations today and you'll see the same contingent of businesses, a few fast-food joints, a gas station, a dollar store. Small, local, sustainable, and culturally cognizant businesses are largely absent as a direct effect of the tribal economic-development models initiated in the early 1920s to ensure successful extraction of natural resources held on tribal lands. Creating entrepreneurial pathways is a sincere route to developing a diverse and more sustainable economy, increase household incomes, and improve health outcomes for residents on tribal lands.

Energy Seminar: Michelle Sim, Director of Sustainability at SoCalGas - 05/17/2021 04:00 PM
Stanford Energy Seminar

Mid-century net-zero targets are abundant these days. But there are a few industries where this type of goal would seemingly be contrary to what is thought to be their core business. On March 23, 2021, SoCalGas became the largest gas distribution utility in the nation as they set a net-zero target across its operations and delivery of energy by 2045. Michelle Sim, Director of Sustainability, will discuss sustainability and their climate commitment to 2045; what it means to them, what it means to their 22 million customers, and what it means to the 500+ communities they serve.

The Weird and Wonderful World of Parasites - Livestream - 05/18/2021 12:00 PM
Audubon Canyon Ranch

What if you had to make your living inside another organism? Better yet - if you had to move between two or three organisms, in different taxonomic groups with different immune systems, to complete your life cycle? What if you were able to alter the behavior or genetics of other organisms to make them more likely to be eaten or to take care of your offspring or to change their personality? Parasites demonstrate the complexity of ecological interactions and just how much we don’t know and how much our view is determined by how we choose to label things. Gwen will be introducing the fascinating world of parasites in the context of intimate interspecific relationships.

SETI Talks: Why is Earth Still Habitable? - Livestream - 05/19/2021 10:00 AM
SETI Institute

Earth, a Pale Blue Dot in our solar system, is also the result of 4 billion years of evolution leading to a technologically advanced and intelligent civilization, humanity. When you look around almost anywhere on Earth, you see life. In the air, in the water, in the land and even underground. But was this inevitable? We know that there have been mass extinction events in the past, some taking out most of life on Earth, but not all of it, since we are here to ponder it.

Current global warming shows us that the climate can change considerably over even a few centuries. Over geological timescales, it is even easier to see climate change. Calculations show that there is the potential for Earth’s climate to deteriorate to temperatures below freezing or above boiling in just a few million years. Abrupt changes can come from natural disasters like super-volcanoes, asteroid impacts, solar flares, supernovae, and many other threatening events. Even the amount of heat from the Sun has increased as it ages, so why is Earth still habitable?

That’s a mystery that we’ll discuss with Sarah Rugheimer and Toby Tyrrell. Sarah is an astrophysicist at Oxford University who studies exoplanet atmospheres, searching for biosignatures and possible life. Toby is a professor in Earth System Science within Ocean and Earth Science, National Oceanography Centre Southampton at the University of Southampton. He recently published a new perspective on why our planet has managed to stay habitable for billions of years.

This work consists of running simulations looking at how 100,000 randomly different planets responded to random climate-altering events spread out across three billion years.

Most of those planets which remained life-sustaining throughout the three-billion-year period only had a probability, not a certainty, of staying habitable.

Is Earth’s success in remaining habitable just a fluke? What can we learn from studying the climate of planets in our solar system and those orbiting other stars?

We hope to answer these questions with our speakers in this conversation moderated by SETI Institute Senior Astronomer Franck Marchis.


Full-Spectrum Science Online: Big & Small - 05/19/2021 04:00 PM

Stronger, Higher, Faster: Big Wave Surfing and Climate Change - 05/19/2021 06:00 PM
KQED

The impacts of climate change are felt all over the world, and Mavericks, the legendary surf break near Half Moon Bay, is no exception. Waves there can crest well above 50-feet during a big swell - and as climate change accelerates, they are changing, too. Becoming bigger, faster, and more powerful. People who know that fact intimately are the surfers themselves. We'll hear from Bianca Valenti, one of the best big wave surfers in the world, and Grant Washburn, a filmmaker and surfer who has chronicled the daily conditions at the break for nearly three decades. We'll watch Bianca's footage from this past year - one of the best seasons in a generation - as she narrates live, and we'll talk over what changes Grant has witnessed. Bring your favorite beach snacks and listen to people who have felt this effect of climate change first hand, their faces right there in the water. Hosted by KQED science reporter Kevin Stark.

COVID-19 Conundrum: Critical Insights on Cloud Security Posture of Enterprises - Livestream - 05/19/2021 07:00 PM
California Section American Chemical Society

In the early days of the COVID-19 pandemic, there was a rapid uptick in demand for cloud services. Organizations globally increased their cloud workloads by more than 20%, leading to an explosion of security incidents. In this talk we'll review the latest cloud threat research from Palo Alto Networks elite group of threat researchers, Unit 42. The talk will walk through findings that indicate cloud security programs for organizations globally are still in their infancy when it comes to security automation (i.e., DevSecOps and shift left). Bottom line: rapid cloud scale and complexity without automated security controls embedded across the entire development pipeline is a toxic combination.

Framers: Human Advantage in an Age of Technology and Turmoil - Livestream - 05/20/2021 10:00 AM
Commonwealth Club - Online Event

Join us for a virtual discussion with the three co-authors of Framers, which focuses on the essential tool that can enable humanity to find its way through the challenges of pandemics, populism, AI, ISIS, wealth inequity, climate change, and other worldwide problems that threaten our current civilizations. To frame is to make a mental model that enables us to see patterns, predict how things will unfold, and make sense of new situations. Frames guide the decisions we make and the results we obtain. Science has long focused on traits like memory and reasoning, but has often ignored framing. But with computers becoming better and better at those cognitive tasks, framing stands out as a critical function - and one only humans can do.

Illustrating their case with compelling examples and the latest research, Cukier, Mayer-Schönberger and de Véricourt examine: why advice to “think outside the box” is useless; why the Wright brothers, with no formal physics training, were the first to fly; what enabled the 1976 Israeli hostage rescue at Entebbe to succeed; and how the #MeToo twitter hashtag reframed the perception of sexual assault. They also show why framing Covid-19 as equivalent to a seasonal flu failed, and how modeling it on SARS succeeded in New Zealand. Framers shows how framing is not just a way to improve how we make decisions in an era of algorithms, but is also an ever more crucial tool in a time of societal upheaval and machine prosperity.

Speakers: Kenneth Cukier, Journalist; Viktor Mayer=Schonberger, University of Oxford; Francis de Vericort, ESMT Berlin, George Hammond, Moderator, Author


The Dark Side of the Universe - Livestream - 05/20/2021 11:30 AM

Blackbirds - A Journey Through the Americas - Livestream - 05/20/2021 05:00 PM
San Francisco Bay Bird Observatory

The Icteridae are the blackbirds, but they include many colorful species such as the orioles and meadowlarks as well as the all-black species, such as cowbirds and grackles. Some of the tropical species, such as the oropendolas are downright amazing-looking and sounding birds. This group of birds is only found in the Americas and they are amongst our most interesting of landbirds, behavior, mating strategies, and breeding biology is more diverse than in any other group of songbirds in our continent. This talk is to introduce people to the awesomely interesting group of birds. After this talk, you won’t walk by a Brewer’s Blackbird or Red-winged Blackbird without thinking about how much more complex they are than a sparrow or a warbler. Our quest to see the diversity of the blackbirds will also take us to some interesting parts of the American continent and the Caribbean.

Where Did it All Come From? Where is it All Going? - Livestream - 05/20/2021 05:00 PM
Cafe Scientifique Silicon Valley

The physical universe, I will argue, is made of matter (or energy) and of order (or information). I’ll trace out the 13.8 billion year history of this matter/energy told by modern cosmology, as it has developed into ever-more sophisticated order and structure: galaxies and their arrangement, stars, planets, life, and very recently and locally, civilization. The survival of civilization - and life itself - through the coming century is not assured, but if it continues, what could its future look like over thousands or millions of years? No one knows, but touring topics from fundamental physics to the nature of intelligence, I will lay out some of the possibilities.

What’s that wiggle? The challenges (and solutions) of using fibre-optic cables as seismological antennas - Livestream - 05/21/2021 12:00 PM
UC Santa Cruz

Fibre-optic Distributed Acoustic Sensing (DAS) is an emerging technology that enables the recording of ground motions with fibre-optic (telecommunication) cables. Since these cables can be deployed in environments that are traditionally challenging for seismometers (underwater, in cities, glaciers, deep boreholes, etc.), we can use DAS to make measurements of seismic waves in sparsely instrumented locations. Moreover, the high spatial- and temporal resolution of DAS data and the low cost of optic fibre makes fibre-optic cables an attractive, low-cost alternative to expensive seismometer arrays. But since DAS is a relatively new technique in geophysics, we do not yet know the extent to which DAS is a valid substitution to seismometers. In this talk I will explain the principles of DAS, go through some interesting applications in geophysics, and discuss in detail what it is that we actually measure (often it is not what we want to measure!). I will conclude by proposing a practical solution of combining DAS arrays with standard seismometers to facilitate the analysis of DAS recordings.

A Walking Tour of Optical History -- Artifacts and Anecdotes from the Astronomical Lyceum - Livestream - 05/21/2021 07:30 PM
Tri-Valley Stargazers

Pioneering telescope makers allowed a revolutionary ascendancy of American astronomy in the 19th and early 20th centuries. The Astronomical Lyceum in New Mexico, originally built in 1936 as a theater and gymnasium, now houses a collection of telescopes, optics, archives, and literature from this ascendancy. Its volunteer staff find the artifacts and associated history surprisingly engaging for visitors of all interest levels. The presentation will include unusual items, large and small, created by some of the America's greatest early optical artists, including Henry and Harry Fitz, Alvan Clark and Sons, Carl and Robert Lundin, John A. Brashear, George Willis Ritchey, and the pioneer of astronomical spectroscopy and photography, Lewis Morris Rutherfurd. The collection includes artifacts originating right up through the Space Age, including from the amateur telescope making movement and its surprising influence. While time allows only an overview, the presentation hopes to remind participants how history of science and technology can be powerfully engaging and interesting for essentially anyone when offered in the right spirit.

Existing evidence in Sports Related Concussions(SRC) is insufficient to determine the best combination of measures in the use of evaluation tools. Three Machine learning methodes and SRC prediction rules are dicussed.This talk describes a hybrid machine learning model based on the combination of human/knowledge based domains and computer generated feature rankings to improve accuracy of diagnosing SRC. Four feature selection criteria were constructed to create the optimal model, which was run on both Google AutoML and Random Forest for validation. The results show that the hybrid model has the best performance in predicting resolution time for 14-day and 28-day thresholds, along with outperforming previous published work. This research has significant impact in the use of domains and symptom ranking with machine learning to increase diagnosis accuracy. The hybrid model’s success in the use of domains to increase the efficiency of model training may have practical applications in real time situations.
