Did Harvard astronomer Avi Loeb discover the remnants of an interstellar meteor in the form of spherules on the ocean floor? Could they be of alien origin? In today's special edition of The Michael Shermer Show the guest, Harvard astrophysicist Dr. Avi Loeb announces that he has discovered material from a large interstellar object from the bottom of the Pacific Ocean near Papua New Guinea in an expedition he led over the summer. The object, which he labels IM1—Interstellar Meteor 1—collided with Earth nearly a decade ago and was tracked by U.S. government satellites, which gave Loeb and his team coordinates of where to look. Most of the meteor burned up in the atmosphere but tiny spherules remained on the ocean bottom, which Loeb retrieved and had analyzed in labs at Harvard, UC Berkeley, and the Broker Corporation. These spherules are tiny—smaller than a grain of sand—and there are literally trillions of them around the world of both terrestrial and extraterrestrial origin, so whether or not these particular spherules are Interstellar in origin remains to be seen, despite Loeb's confidence that they are. Here is what he announced today in a press release: The Interstellar Expedition of June 2023–led by the expedition's Chief Scientist, Harvard University Astrophysicist Avi Loeb and coordinated by Expedition Leader Rob McCallum of EYOS Expeditions retrieved hundreds of metallic spheres thought to be unmatched to any existing alloys in our solar system from the seafloor in the Pacific Ocean near Papua New Guinea. Early analysis shows that some spherules from the meteor path contain extremely high abundances of Beryllium, Lanthanum and Uranium, labeled as a never-seen-before “BeLaU” composition. These spherules also exhibit iron isotope ratios unlike those found on Earth, the Moon and Mars, altogether implying an interstellar origin. The loss of volatile elements is consistent with IM1's airburst in the Earth's atmosphere. “The “BeLaU” composition is tantalizingly different by factors of hundreds from solar system materials, with beryllium production through spallation of heavier nuclei by cosmic-rays flagging interstellar travel,” says Avi Loeb. The press release of August 29, 2023 was timed with the publication date of Dr. Loeb's new book, Interstellar, whose subtitle hints at the scientist's larger ambitions: The Search for Extraterrestrial Life and Our Future in the Stars. Dr. Loeb's co-authored paper has not been peer reviewed. In fact, none of the world's leading experts on spherules from space have even seen any of Dr. Loeb's evidence. So in preparation for this episode, I contacted Peter Brown, an astronomer at Western University, Ontario, who specializes in the physics of meteors, and he directed me to the five leading experts in the world on spherules. These include: George Flynn, SUNY, Plattsburgh; Don Brownlee, University of Washington; John Bradley, University of Hawaii; Michael Zolensky, NASA; and Matthew Genge, Imperial College, London. I also consulted Steven Desch, from Arizona State University, as he has been quoted elsewhere as a critic of Avi Loeb's research. All expressed their skepticism about Dr. Loeb's findings, which I read on air to Avi to get his response. (See the show notes for this episode on skeptic.com.) Listen to the experts and Dr. Loeb's response to their skepticism in this episode. (Note: Steven Desch's initial statement, included in the show notes, was so negative that I chose not to read it on air, but include it in the show notes on skeptic.com for full disclosure of what he thinks about this research. I also included Dr. Desch's additional comments on why many scientists are skeptical of the U.S. government data on the meteor's trajectory and impact site.) I should note that I am a member of the Galileo Project team, which organized this expedition, and I consider Avi a friend and colleague who always welcomes my skepticism in our weekly team meetings. To that end let me emphasize that he is not claiming to have discovered alien technology, only the remnants of an interstellar object. Unfortunately, the media coverage surrounding the Galileo Project in general and this expedition in particular is only interested in whether or not we have made contact with ET. We have not, and Avi is not claiming that we have. No matter the scientific find is, the media reports it as aliens, aliens, and aliens. Alas. My own view is that aliens are very likely out there somewhere—given the astronomical numbers of hundreds of billions of galaxies, each of which has hundreds of billions of stars, each of which has planets it seems highly unlikely that we're alone in the cosmos—but that they have very likely not come here in any shape or form—nonhuman biologics or extraterrestrial metalogics (my own neologism echoing government whistleblower David Grusch's ridiculous description of alien pilots as “nonhuman biologics” in his Congressional testimony). The universe is vast and consists of mostly empty space. The odds are very long indeed that anyone could find us, much less leave traces for us to evaluate. But in keeping with Cromwell's Rule in Bayesian reasoning (never assign a 0 or 1 probability to anything because, as Oliver Cromwell famously said, “I beseech you in the bowels of Christ you might be mistaken”), we should keep an open mind and keep looking. That is why I support the SETI program and am on the Galileo Project team. The odds are long but the payoff would be spectacular if we ever did discover extraterrestrial intelligence or the technological artifacts of an extraterrestrial civilization. Abraham (Avi) Loeb is the Frank B. Baird, Jr., Professor of Science at Harvard University, the longest-serving chair of Harvard's Department of Astronomy, the founding director of Harvard's Black Hole Initiative, and the current director of the Institute for Theory and Computation (ITC) within the Harvard-Smithsonian Center for Astrophysics. He also heads the Galileo Project, chairs the Advisory Committee for the Breakthrough Starshot Initiative, and is former chair of the Board on Physics and Astronomy of the National Academies. Author of eight books and more than a thousand scientific papers, Loeb is an elected fellow of the American Academy of Arts and Sciences, the American Physical Society, and the International Academy of Astronautics. In 2012, Time selected Loeb as one of the 25 most influential people in space. He lives near Boston, Massachusetts.

Monica Is a group leader at ICIQ (Institut Català d'Investigació Química / Institute of Chemical Research of Catalonia), Tarragona, Spain. Her group focuses on the ‘Development of new chemical transformations: From organometallic mechanistic studies to catalysis'. Prior to her current position, Monica conducted postdoctoral research at the University of Michigan, Ann Arbor, USA, which followed awarding of her Ph.D. from the University of Valladolid, Spain – where she also earnt her B.Sc. and M.Sc.In 2018, Monica was selected as one of the ‘Talented 12' by Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society (ACS). She is also involved in outreach activities to increase the visibility of women in Science. You will hear the following terms used during the interview. I've included some descriptions here. NMR – Nuclear Magnetic Resonance subjects samples to a strong magnetic fields and measures the resonance pattern of the nuclei. It is widely used to study the structure and dynamics of organic molecules.Palladium – A chemical element with atomic number 46. It is a rare metal and over 50% of palladium supply is used in catalytic processes, most commonly catalytic converters attached to automobile exhausts.Cobalt A chemical element with atomic number 27. Most commonly produced as a by-product of Copper and Nickel production, the main use for colbalt is in Li-ion batteries, and the production of certain high-strength metal alloys.Transition metal – in chemistry, the term transition metal is defined in one of three ways:Many scientists describe a "transition metal" as any element in the d-block of the periodic table, which includes groups 3 to 12 on the periodic table. In practice, the f-block lanthanide and actinide series are also considered transition metals and are called "inner transition metals".The IUPAC definition defines a transition metal as "an element whose atom has a partially filled d sub-shell, or which can give rise to cations with an incomplete d sub-shell".The expanded IUPAC definition specifies which elements are included. As well as the elements of groups 4 to 11, scandium and yttrium are included Lanthanum and actinium, which are considered group 3 elements, are however classified as lanthanides and actinides respectivelyNucleophile – A chemical species that forms bonds with electrophiles by donating an electron pair.Oxidant – A substance that has the ability to oxidize another substance. In chemical reactions this refers to the oxidant accepting electrons.Intermediate – A chemical entity that is formed during a reaction, but that is typically converted to another form when the reaction completes. During the discussion, Monica mentions a number of the publications that her groups have produced. Links to her publications are available from the group website. Monica is contactable on social media, and you can find her on LinkedIn https://www.linkedin.com/in/monica-h-perez-temprano-3659ab3b/ The group website is https://www.iciq.org/research/research_group/dr-monica-h-perez-temprano/ On Twitter, the group is @Perez_Temprano Our theme music is "Wholesome" by Kevin MacLeod (https://incompetech.com)Music from https://filmmusic.ioLicense: CC BY (http://creativecommons.org/licenses/by/4.0/) Connect with me (Paul) at https://www.linkedin.com/in/paulorange/H.E.L. group can be found at www.helgroup.com online,on LinkedIn at https://www.linkedin.com/company/hel-group/ on Twitter, we're @hel_group, https://twitter.com/hel_groupor search for us on Facebook

Let's uncover element 57, and find out why the "rare earths" are neither rare nor earths nor an empire.

The element that some say shouldn't be called what it's called. We voyage into the world of Lanthanum.

Despite giving its name to a whole group on the periodic table, chemists can't agree if lanthanum even belongs in that group, says Prof Allan Blackman from AUT in ep 42 of Elemental.

Hold on to your protons… because in this edition of the Modern Moron we change our initials MM to Miraculous Madduri.  If you remember some time ago I interviewed Achyntia Madduri who has a PhD in Electrical engineering. His work involved independent solar grids that could be deployed to disaster victims.  Well in this show we’re going to talk to the block that he is a chip off of as they say, his father, Dr. Somayazulu Madduri. He is a scientist as well and is part of a breakthrough in superconductors and superconductivity.  What the heck is that? Don’t ask me, but we are going to ask him to dumb it down or Moron it down for us.  To do their thing, superconductors need very high pressure and very low temperatures, minus 300 degrees almost, because they generate a lot of heat.  Well Dr. Zulu, as they call him, has been part of a team that has figured out how to do it at almost room temperature. And that’s a very big breakthrough… how big?  I can’t put it into perspective but we talk about Star Wars for a second so that’s big enough for me.  I’ll also include a link to a very short straightforward article about his work. We also talk about Hinduism and bringing up children in a household that embraces both science and religion as part of the same journey. You’re going to hear words you don't’ normally hear on this program.  Here are a few… maybe you can use them on your daily crossword puzzles... Lanthanum - A chemical element. It is a soft, silvery-white metal that tarnishes rapidly when exposed to air and is soft enough to be cut with a knife.  It’s used for flint in lighters and is used in the semiconductors in Dr. Zulu’s experiments. “Dynamo” which is not only a way to describe the Senator’s personality but is literally a generator for turning mechanical energy into electrical energy. Epistemology - the branch of philosophy concerned with the theory of knowledge. Upanishads - are ancient Sanskrit texts that contain some of the central philosophical concepts and ideas of Hinduism, some of which are shared with religious traditions like Buddhism. See how much benefit you’re getting from making the Modern Moron part of your day? https://phys.org/news/2019-01-evidence-superconductivity-room-temperature.html

The rare earth elements are the focus of the latest instalment in Business Daily's exploration of the real basis of the world economy - the basic building blocks of everything in the universe, the chemical elements.And it's not a short list we cover: Lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, turbium, dysprosium, holmium, erbium, thulium, ytturbium and lutetium. You may not have heard of most of them but some have insinuated themselves deep into modern life. We'll be finding out the extraordinarily range of uses to which they've been put, as well as the big problem: The supply of these is overwhelmingly dominated by China.We'll be hearing from Professor Andrea Sella of University College London, Jack Lifton of Technology Metals Research, the journalist Cecile Bontron who provides a first-hand account of the Chinese processing plant at Baotou, as well as Henrik Stiesdahl and Rasmus Windfeld of Siemens' wind turbine division.

This is the first chapter of Lanthanum Towers, performed live at Farpoint.

The present study was designed to determine the effect of different types and concentrations rare earth elements on growth performance of Japanese quails. 120 and 225 one day old Japanese quails in the first and third experiment respectively were allotted to five dietary treatments: a control group and four REE groups which were supplemented with 50,100, 400 and 800 mg/kg of REE-citrate, a Lanthanoid mixture. In the second experiment 300 one day old Japanese quails were allotted to eight dietary treatments: a control group and seven REE groups which were supplemented with 50 or 100 mg/kg of REE-citrate (type A), lanthanum acetate (type B), lanthanum chloride (type C) and lanthanum carbonate (type D). Each experiment lasted four weeks and during it feed and water was ad libitum. The REE supplements increased the weight gain of Japanese quails compare to control group by 18.5-22% during the first experiment (p
