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.
