Unwilling to stay silent, 139 employees of the Environmental Protection Agency signed a letter listing 5 criticisms of Administrator Lee Zeldin’s actions:
Undermining public trust
Ignoring scientific consensus to benefit polluters
Reversing EPA's progress in America's most vulnerable communities
Dismantling the Office of Research and Development
Promoting a culture of fear; forcing staff to choose between their livelihood and their well-being
The EPA’s response was to suspend the signers and falsely denigrate them as “career bureaucrats unlawfully undermining, sabotaging, and undercutting the administration’s agenda as voted for by the great people of this country last November.”
You and i must continue standing up for science, integrity, compassion.
SPACE
We’ve spotted another visitor from beyond the Solar System. Because Comet 3I/ATLAS is moving at 60 kps, it will easily escape from the Sun's gravity and continue on into interstellar space. It could be as large as 24 km across. [“Rendezvous with Rama” was one of my favorite books.]
Satellite insurance?? Yes, because the rocket might fail to deliver the satellite to its planned orbit, or the satellite might collide with some other satellite (collision insurance??), or the satellite could be shredded by orbiting debris. Last year for the first time, insurance payouts exceeded collective insurance premiums. Insurers are dropping out of the market. Sounds a bit like the home insurance market in California.
Here is a 24-page e-booklet from the SETI Institute describing the search for extraterrestrial intelligence.
A space elevator to assist in launching payloads from Earth is not yet technologically possible. But a space elevator anchored to the Moon is possible and it would facilitate exploration and mining operations. This web page includes a 15-minute video by one of the scientists who verified its feasibility.
For fun, take this 10-question quiz about galaxies.
RAFFLE
We are offering this 30cm diameter black wall/table clock displaying the first 12 elements of the periodic table with their atomic weights. Just send an email before noon Friday to david.almandsmith [at] gmail.com with your guess of an integer between 0 and 1,000. Last time we had a 3-way tie (a first) with the 24 contestants when the eOracle revealed 613. During the 2nd round the eOracle revealed 434 and Robert won a white caffeine molecule mug.
SCIENCE-BASED SKEPTICISM
A friend of mine firmly believes in the Pleiadeans - blond blue-eyed beings from a higher dimension who are shepherding us through ‘these difficult times.’ Roughly a third of Americans believe we are being visited by aliens from far-distant stars or from other dimensions, and over half believe our government knows more than they are telling. A concerning fallout from this nonsense is the growing distrust of governments and scientists.
Tom Nichols in his book, “The Death of Expertise”, claims “Americans have reached a point where ignorance, especially of anything related to public policy, is an actual virtue.”
Not surprisingly, the business model used by social media platforms exacerbates the spreading of misinformation.
On a positive note, sales of homeopathic ‘remedies’ are declining, and British secondary students are better at identifying ‘fake news’ than are their parents.

PHYSICS
Space-time is at the root of gravity and our understanding of the cosmos, but is space-time an emergent phenomenon of a deeper reality? To understand how physicists are exploring the underpinnings of space-time, Quanta Magazine produced this 9-part survey.
BIOLOGY / ETHOLOGY
Twenty-nine years ago, Dolly the sheep was born. Dolly matured using DNA of a somatic cell of breast tissue (hence named after Dolly Parton) from one ewe , inserted into an enucleated egg cell [oocyte] of a second ewe, and implanted into the womb of a third ewe. Dolly had no genetic father. This year for the first time, healthy adult mice each matured using the haploid genomes of two mouse sperm cells inserted into a mouse enucleated egg cell, and implanted into the womb of another mouse. These male mice have no genetic mother; only fathers.
Ninety-nine million years ago, a number of wasps were trapped and preserved in amber. What makes them peculiar are posterior flaps lined with spikes apparently adapted for trapping bugs. Like Venus Fly Traps, the wasps could trap living prey.

SETI Live: How Ceres Froze Over - 07/07/2025 02:30 PM
SETI Live
Join planetary scientist Beth Johnson and Dr. Ian Pamerleau, lead author of a groundbreaking new Nature Astronomy study, for a deep dive into the icy mysteries of Ceres - the largest object in the asteroid belt and the only dwarf planet to be orbited by a spacecraft.
While Ceres shows signs of an ice-rich interior, its heavily cratered surface doesn’t behave like soft, ice-laden terrain. So what gives? To solve the puzzle, Pamerleau and colleagues used simulations and an updated model of how impure ice deforms. Their work reveals that Ceres once hosted a subsurface ocean that froze from the top down, concentrating impurities as it solidified and creating a gradient from ice-rich surface layers to a rockier interior.

Wonderfest: The 'Trial of the Century': Scopes at 100 - 07/08/2025 07:00 PM
Hopmonk Tavern Novato
2025 marks the 100th anniversary of the “Trial of the Century”: Tennessee vs. John T. Scopes, the first major legal assault against the teaching of evolution in America. Mostly because of the fictional movie Inherit the Wind, the Scopes “monkey trial” is wrongly perceived as a victory for evolution over the forces of obscurantism. The full story is much more complex and interesting, involving science, religion, law, education, politics, celebrities, modern communications, and the politicization of science.
Our Wonderfest speaker is physical anthropologist Dr. Eugenie Scott, author of Evolution vs. Creationism: An Introduction, and former director of the National Center for Science Education.

Dropped Prey of the Endangered California Least Tern - 07/09/2025 10:00 AM
ExplOratorium San Francisco
Explore the foraging habits of the California least tern in San Francisco Bay! This endangered seabird nests in Alameda during the summer, plucking fish from the upper waters of the Bay and bringing them back for their chicks to eat. Sometimes the terns drop the fish on the ground. Why would they do that? It could be the fish is too large for a chick to eat, the chicks aren’t hungry, or the parent drops it by accident. In any case, it will not be eaten, and this presents an opportunity for scientists in the marine lab at Point Blue Conservation Science to learn about the prey available to the least tern. In studying what the least terns actually eat (through analyzing feces and regurgitated pellets) and what they drop on the ground, we have learned that the species dropped are similar to those that are consumed. Jacksmelt, topsmelt, and northern anchovy are some of the least tern’s favorite fish, but other species, such as Pacific herring and shiner surfperch, also appear in dropped prey collections. Learn how we identify these fish, and what implications different prey have on the recovery of this endangered seabird.
Systemic Racism in Science Communication - 07/09/2025 10:00 AM
Berkeley Way West Berkeley
The importance of increasing public understanding of scientific issues, like the environment and health, is rising, especially in our most vulnerable communities. As a result, scientists are learning the importance of making their work more accessible. But first, we must confront the inequities embedded within the systems that we exist in. This lecture explores how systemic racism shapes who is heard, who is represented, and who benefits from science communication. We’ll discuss strategies for building equity into your science communication efforts - from choosing inclusive language to partnering with underrepresented communities and elevating historically marginalized voices.

Fish Here, Fish There, Fish Detected Everywhere: Developing AI to find Salmonids in Sonar - Livestream - 07/09/2025 11:00 AM
Monterey Bay Aquarium Research Institute
Salmon and trout (salmonids) are keystone species in the Pacific Northwest, but their populations are threatened by overfishing, habitat loss, and climate change. Accurate population monitoring is essential to understand and address these risks, yet current methods are manual and laborious. Counting by watching sonar imagery is widely trusted, which invites the question - can we teach a machine to interpret this imagery? Sonar presents unique challenges for computer vision: the images are noisy, fish are often obscured or occluded, and environmental conditions change over time. Our research aims to automate detection, tracking, and counting of salmonids in sonar videos using AI. We explore approaches such as self-supervised denoising to improve image clarity, training-free bayesian estimation to distinguish foreground from background, domain adaptation to address differing camera placements, and keypoint-tracking to automatically track areas of interest. Early results are promising, suggesting that automated systems could provide reliable, efficient population estimates and greatly reduce the need for manual counting.

How the Pyramid Scheme Shaped America - Livestream - 07/10/2025 04:00 PM
Skeptical Inquirer
Multilevel marketing (MLM) is (by design) difficult for most people to understand. These programs offer a world of pink Cadillacs, white-columned mansions, tropical vacations, and - most precious of all - financial freedom. But overwhelming evidence suggests that most people lose money in multilevel marketing and that many MLM companies are pyramid schemes. So how is this legal? And what are the people at the top doing with all that money?
Join us for a Skeptical Inquirer Presents livestream with Bridget Read. Her new book, Little Bosses Everywhere: How the Pyramid Scheme Shaped America, examines the stranger-than-fiction world of multilevel marketing: a massive money-making scam and radical political conspiracy that has remade American society. Read will explain exactly what MLM is, the history of the industry, and the incredible damage that can result for participants??"and society at large.

The list of individuals who have managed to escape the rabbit hole of conspiracism is short, but there is an even shorter list of individuals who have then gone on to become popular skeptical podcasters. Former conspiracy enthusiast Coleman Watts discusses why people fall for cults and cons, and how he managed to climb out of the rabbit hole. What’s the best way to talk to a conspiracy theorist to dissuade - and persuade - them from their views? Is misinformation taking over, and if so, why? Coleman Watts will talk about all of this and more in an engaging talk about his experiences debunking the views he used to embrace.
Speaker: Coleman Watts is the host of Think This Through on YouTube. He debunks cons, cults, and conspiracies with a humorous flair.

Broader Impacts 2.0 - Livestream - 07/11/2025 10:00 AM
Science at Cal
“Broader impacts” describe the effects of research on society - the benefits beyond academia through avenues like public policy, the economy, science literacy, and community partnerships. This session, co-hosted with the Berkeley Research Development Office, demystifies NSF’s broader impacts criterion and offers concrete tools for designing, evaluating, and embedding meaningful societal benefits into your science. With recent updates to NSF guidelines, we’ll also cover strategies for meeting new expectations. In today’s climate - where science faces increasing scrutiny - communicating public relevance is not just valuable, it’s essential. Developing these skills has also become a critical component of grant applications across all agencies (local, state, and federal) and foundations, as well as preparing successful application packages for career positions, awards, and promotion and tenure cases.

New Technology for Exploring Other Worlds - 07/12/2025 07:30 PM
San Jose Astronomical Association San Jose
Planets around other stars are not just the domain of science fiction anymore. Over the past 30 years astronomers have gone from no knowledge of planets around other stars to being able to say how common or rare they are (spoiler: they’re common). Are any of these planets habitable? Do any of them have life? To learn this, we need to develop improved telescopes and instrumentation. Two key tools for this are adaptive optics (AO) and the development of large segmented mirror telescopes(LSMT). AO corrects for the blurring effects of our atmosphere, allowing us to effectively separate the planet from the overwhelmingly brighter light of its parent star. I will discuss the technology development being carried out at the UC Observatories to integrate AO and LSMT technology. The resulting large aperture adaptive telescope concept can provide the light gathering capability and precision imaging needed to scour our neighboring stars for Earth-twin planets.

The Sun and the Earth: A Magnetic Connection - 07/14/2025 07:30 PM
California Academy of Sciences San Francisco
From our daily routines to seasonal changes, there are so many ways to experience our relationship with the Sun. For something upon which we rely so heavily, there are still quite a few mysteries that surround it! One of the biggest questions scientists have about the Sun seems so simple: Why is the Sun’s atmosphere so hot? Finding the answer to this question is a driving force behind solar physics today, and the key to solving this mystery might just unlock a few other clues along the way.
Join Dr. Robinson on a journey that begins deep inside the Sun, where superheated plasma flows generate the Sun’s tangled magnetic field. Learn how the magnetic field shapes and is shaped by the diffuse Solar atmosphere, and how resulting magnetic explosions offer crucial insights into unveiling the secrets of the Sun’s atmospheric processes.
Soon to join NASA’s proud fleet of Heliophysics missions, the Multi-Slit Solar Explorer (MUSE) is designed to collect the signatures of bright magnetic events in the Sun’s atmosphere and analyze them with unprecedented spectral detail. New data from MUSE will help us better understand not only the Sun’s atmosphere, but also how Earth’s relationship with the Sun is dictated by dynamic Solar magnetism.
