For Immediate Release Contact: [email protected] ARTIST CREATES NEW UNIVERSE FROM URANIUM AND CHEWING GUM Novel Technique Puts Quantum Theory to Practical Use. Automated Universe Factories Planned for Government and Industry. San Francisco Gallery to Begin Selling $20 D.I.Y. Universe Kits on November 20th. Universes Provide Alternatives to Recession October 31, 2008 - Following decades of effort by engineers to build quantum supercomputers and to master quantum cryptography, today quantum physics has spawned a far more powerful technology. Applying theory developed by deceased Princeton physicist Hugh Everett III, and using little more than a piece of chewing gum, a plastic drinking straw, and a bit of uranium, San Francisco conceptual artist Jonathon Keats has constructed the first machine for fabricating all-inclusive universes. "It was a product of my anxiety," admits Mr. Keats. "I'd recently had a couple museum shows, yet I was feeling that no matter what I made, it was hardly comparable to the creation of the cosmos. And though no one talks about it, the same issue faced Picasso, Monet, even Michelangelo. The Big Bang has artists beat." Taking on the cosmos as a creative challenge, Mr. Keats began researching an aspect of quantum mechanics proposed by Dr. Everett in the 1950s and later refined by scientists including David Deutsch at Oxford and Wojciech Zurek at Los Alamos National Laboratory. Dr. Everett's theory addressed the question of how a subatomic particle can exist in a quantum superposition - for example being in two places at once - until someone observes it, at which point the observer finds it to be in only one place at a time. -

Amino Acids and the Asymmetry of Life; Springer, 2008.Pdf
Amino Acids and the Asymmetry of Life Advances in Astrobiology and Biogeophysics springer.com This series aims to report new developments in research and teaching in the inter- disciplinary fields of astrobiology and biogeophysics. This encompasses all aspects of research into the origins of life – from the creation of matter to the emergence of complex life forms – and the study of both structure and evolution of planetary ecosystems under a given set of astro- and geophysical parameters. The methods con- sidered can be of theoretical, computational, experimental and observational nature. Preference will be given to proposals where the manuscript puts particular emphasis on the overall readability in view of the broad spectrum of scientific backgrounds involved in astrobiology and biogeophysics. The type of material considered for publication includes: • Topical monographs • Lectures on a new field, or presenting a new angle on a classical field • Suitably edited research reports • Compilations of selected papers from meetings that are devoted to specific topics The timeliness of a manuscript is more important than its form which may be un- finished or tentative. Publication in this new series is thus intended as a service to the international scientific community in that the publisher, Springer-Verlag, offers global promotion and distribution of documents which otherwise have a restricted readership. Once published and copyrighted, they can be documented in the scientific literature. Series Editors: Dr. André Brack Dr. Christopher P.

Received: 22 February 2019; Accepted: 11 March 2019; Published: 16 March 2019 Abstract: The biomolecular homochirality in living organisms has been investigated for decades, but its origin remains poorly understood. It has been shown that circular polarized light (CPL) and other energy sources are capable of inducing small enantiomeric excesses (ees) in some primary biomolecules, such as amino acids or sugars. Since the first findings of amino acids in carbonaceous meteorites, a scenario in which essential chiral biomolecules originate in space and are delivered by celestial bodies has arisen. Numerous studies have thus focused on their detection, identification, and enantiomeric excess calculations in extraterrestrial matrices. In this review we summarize the discoveries in amino acids, sugars, and organophosphorus compounds in meteorites, comets, and laboratory-simulated interstellar ices. -
Rosetta/COSAC
C4PO research themes 10.1 ESA’s Cometary Mission Rosetta-Philae A. Context and state of the art Uwe Meierhenrich, member of the Institut Convergence, is involved as Co-Investigator (Co-I) in the COSAC experiment of the Rosetta-Philae mission. He is in particular in charge of the chirality-part of COSAC: ESA’s Rosetta mission [1], successfully launched in March 2004, reached its target comet 67P/Churyumov- Gerasimenko (67P/C-G) in 2014. Contrary to its predecessor missions Giotto and Vega to comet 1P/Halley [2,3], Deep-Space 1 to comet 19P/Borrelly [4], Stardust to comet 81P/Wild 2 [5], and Deep Impact to comet 9P/Tempel 1 [6], Rosetta is the first space mission designed and constructed to follow a cometary nucleus through perihelion passage and to deposit a landing unit on the cometary nucleus. In November 2014 the Philae lander detached from the Rosetta spacecraft and landed on the surface of the cometary nucleus that was of unknown morphology and chemical composition. Philae contains the cometary sampling and composition (COSAC) instrument that is equipped with a chirality module for the in situ identification, separation, and quantification of organic molecules including enantiomers expected to be present in cometary ices. The COSAC analysis was assumed to provide essential information on the Solar System formation and possibly on the origin of organic molecules and molecular asymmetry in biological systems [7]. COSAC is equipped with a multi-column gas chromatograph (GC), a time-of-flight mass spectrometer (TOFMS), and connected to an electronic system that allows remote operation of the suite. -

Sproat III Director Office of Civilian Radioactive Waste Management United States Department of Energy Washington, DC 20585 November 19, 2008 Dear Mr. Edward F. Sproat III, It has recently come to our attention that you’re planning to build the nation’s largest nuclear waste repository at Yucca Mountain in the State of Nevada. Please first allow us to extend our congratulations to you and your team. We are impressed by the scope of your ambition. It is clear that your governmental division, the Office of Civilian Radioactive Waste Management, United States Department of Energy, is particularly farsighted. Second, we want to offer our services, which we can state with confidence are uniquely suited to your special project. Universes Unlimited is the foremost purveyor of equipment for macrocosmic fabrication. Our quantum decoherence engine is the only machine purpose-built for all-encompassing creation. On behalf of government and industry, we design state-of-the-art factories to mass-produce full-scale universes. And we are pleased to inform you that the Yucca Mountain Nuclear Waste Repository is a premier site for the largest universe factory in the world. You should know that your planned facility need be modified only slightly to serve this valuable secondary purpose. Because our quantum decoherence engines are atomic, a universe factory can recycle your unwanted gamma rays, as well as your decaying alpha and beta particles. In other words, Mr. Edward F. Sproat III, your nuclear waste need not go to waste. -
Artificial Comet Contains Building Blocks of Life 21 March 2012
Artificial comet contains building blocks of life 21 March 2012 space mission 'Rosetta'. The program aims to place a lander on the comet Churyumov-Gerasimenko to study the composition of its nucleus. In a bid to anticipate Rosetta's findings, the scientists decided to create an artificial comet, or 'simulation of interstellar/cometary ice', and analyze its composition. The team led by Louis Le Sergeant d'Hendecourt was in charge of creating a micro-comet at the Institut d'Astrophysique Spatiale. Under extreme conditions similar to those found in space (-200 °C and in a vacuum), the researchers condensed a number of compounds found in the interstellar medium, such as water (H2O), ammonia (NH3) and methanol (CH3OH) molecules, onto a solid piece of Chromatogram of the cometary ice obtained using the magnesium fluoride (MgF2), while subjecting them multidimensional gas chromatograph.
