FROM LONGITUDE to ALTITUDE: INDUCEMENT PRIZE CONTESTS AS INSTRUMENTS of PUBLIC POLICY in SCIENCE and TECHNOLOGY Clayton Stallbau
FROM LONGITUDE TO ALTITUDE: INDUCEMENT PRIZE CONTESTS AS INSTRUMENTS OF PUBLIC POLICY IN SCIENCE AND TECHNOLOGY Clayton Stallbaumer* I. INTRODUCTION On a foggy October night in 1707, a fleet of Royal Navy warships ran aground on the Isles of Scilly, some twenty miles southwest of England.1 Believing themselves to be safely west of any navigational hazards, two thousand sailors discovered too late that they had fatally misjudged their position.2 Although the search for an accurate method to determine longitude had bedeviled Europe for several centuries, the “sudden loss of so many lives, so many ships, and so much honor all at once” elevated the discovery of a solution to a top national priority in England.3 In 1714, Parliament issued the Longitude Act,4 promising as much as £20,0005 for a “Practicable and Useful” method of determining longitude at sea; fifty-nine years later, clockmaker John Harrison claimed the prize.6 Nearly three centuries after the fleet’s tragic demise, another accident, also fatal but far removed from longitude’s terrestrial reach, struck a nation deeply. Just four days after its crew observed a moment’s silence in memory of the Challenger astronauts, the space shuttle Columbia disintegrated upon reentry, killing all on board.7 Although * J.D., University of Illinois College of Law, 2006; M.B.A., University of Illinois College of Business, 2006; B.A., Economics, B.A., History, Lake Forest College, 2001. 1.

Molecular manufacturing is a method conceived for the processing and rearrangement of atoms to fabricate custom products. It would rely on the use of a large number of molecular electro-mechanical subsystems working in parallel and using commonly available chemicals. Built to atomic specification, the products would exhibit order-of-magnitude improvements in strength, toughness, speed, and efficiency, and be of high quality and low cost. In Part 1: Technical Issues, I pro- vide an overview of molecular nanotechnology and explore ways in which molecu- lar manufacturing could be applied to improve textile products. -

Using DNA self-assembly, materials can be controlled at the nano scale to achieve atomic- or nano-scaled fabrication. The programmability and addressability of DNA molecules can be applied to realize the self-assembly of materials from the bottom-up, which is called DNA nanotechnology. DNA nanotechnology does not focus on the biological functions of DNA molecules, but combines them into motifs, and then assembles these motifs to form ordered two-dimensional (2D) or three-dimensional (3D) lattices. These lattices can serve as general templates to regulate the assembly of guest materials. In this review, we introduce three typical DNA self-assembly strategies in this field and highlight the significant progress of each. -
Intelligent Nanosystems Based on Molecular Motors
Digest Journal of Nanomaterials and Biostructures Vol. 4, No. 4, December 2009, p. 613 - 621 APPLICATIONS OF MOLECULAR MOTORS IN INTELLIGENT NANOSYSTEMS H. R. Khataeea, A. R. Khataeeb* aDepartment of Computer Engineering, Payam Noor University of Hashtrood, Hashtrood, Iran bCorresponding author: Department of Applied Chemistry, Faculty of Chemistry, University of Tabriz, Tabriz, Iran All cells of living organisms contain complex transport systems based on molecular motors which enable movement on their polymer filaments. Molecular motors are responsible for various dynamical processes for transporting single molecules over small distances to cell movement and growth. Molecular motors are far more complex than any motors that have yet been artificially constructed. Molecular motors are ideal nanomotors because of their small size, perfect structure, smart and high efficiency. Recent advances in understanding how molecular motors work has raised the possibility that they might find applications as nanorobots. Constructing of biomimetic nanorobots and nanomachines that perform specific tasks is a long-term goal of nanobiotechnology. Thus, in this paper we have summarized some of potential applications of molecular motors. Our reviewing of potential applications of molecular motors indicates that these extraordinary systems can be had potential applications in nanorobots, nanodevices and nanomedicine. This review indicate that molecular motors might be the key to yet unsolved applications in vast variety of sciences that are only imagined today. (Received September 1, 2009; accepted Septemberv 27, 2009) Keywords: Nanobiotechnology, Nanorobots, Nanomachines, Nanodevices, Nanomedicine, Molecular motors 1.

And Transhumanism Robert Ranisch & Stefan Lorenz Sorgner Scientific and Technological Advances Have Questioned Predominant Doctrines Concerning the Human Condition
Introducing Post- and Transhumanism Robert Ranisch & Stefan Lorenz Sorgner Scientific and technological advances have questioned predominant doctrines concerning the human condition. Transhumanism and posthumanism are among the most recent and prominent manifestations of this phenomenon. Debates on trans- and posthumanism have not only gained a considerable amount of aca- demic and popular attention recently, but have also created a widespread con- ceptual confusion. This is no surprise, considering their recent dates of origin, their conceptual similarities, and their engagements with similar questions, top- ics, and motifs. Furthermore, trans- as well as posthumanism frequently question their relationship to humanism1 and reconsider what it means to be human. In this regard both movements are streaming beyond humanism. What this means, however, is far from clear and shall be subject of discussion in this volume. In order to make sense of these two approaches and to investigate their inter- relationship, a clarification of these concepts is necessary. As a first approxima- tion, transhumanism can be seen as a stance that affirms the radical transfor- mation of human’s biological capacities and social conditions by means of tech- 1 We will not be able to address the complex histories and varieties of humanism in this chapter. Yet, the following must be noted: The word “humanism” (Humanismus) was coined in 1808 by the German theologian and philosopher Friedrich I. Niethammer in the context of educational curricula, as it is derived from the Latin word humanitas. This word has a variety of meaning but has strongly been identified with the Greek word paideia (παιδεία), e.g., i.) in Cicero’s De Oratore (I, 71) the meaning of the concept hu- manitas corresponds to that of the concept paideia; ii.) in the text Noctes Acticae (XIII, 17) by the Latin author Aulus Gellius, who lived in the 2nd century, an explicit identifi- cation of paideia and humanitas can be found. -

The question providing the theme for the present issue of Philosophia Scientiæ is, of course, adapted from Richard Feynman’s well-known speech at the 1959 meeting of the American Physical Society. On this occasion he attracted physicists’ attention to the vast potential of working at the scale of the nanometre if not the ångström, using the catchy title: “Plenty of Room at the Bottom” [Feynman 1959]. This hookline from a famous Nobel laureate physicist served as a motto for the emerging field of nanoscience and nanotechnology (which we will here abbreviate to nanoresearch) in the early 2000s. -

Application of Molecular Simulation Techniques to the Design of Nanosystems
UNIVERSITAT POLITÈCNICA DE CATALUNYA DEPARTAMENT D’ENGINYERIA QUÍMICA APPLICATION OF MOLECULAR SIMULATION TECHNIQUES TO THE DESIGN OF NANOSYSTEMS Francisco Rodríguez Ropero Advisors: Dr.Carlos Alemán Llansó y Dr. David Zanuy Gómara Barcelona, September 2009 i OBJECTIVES (1) Improve the stability of tubular nanodevices based on highly regular β-helical motifs excised from naturally occurring proteins by replacing targeted natural residues by conformationally constrained synthetic amino acids. (2) Model and characterize a dendronized polymethacrylate carrying second generation chiral 4-aminoproline-based dendrons and a thiophene based dendronized polymer in order to explain, in basis of their structure, the extraordinary stiffness of the first and the great conductivity exhibited by the latter in previous experimental studies. (3) Study of the interactions of thiophene based conducting polymers. The interaction of these polymers with the solvent medium as well as their intermolecular interactions such as π-stacking interactions play a key role when designing new devices based on conducting polymers. (4) Exploit the intrinsic tubular geometry of natural motifs extracted from certain proteins together with the ability of π-conjugated systems to promote charge transfer to model a tubular electronic conductor based on natural peptide sequences by replacing natural amino acids by synthetic amino acids owning an aromatic side chain. (5) Study of the role played by the solvent molecules in the actuation mechanism in the molecular actuator poly(calix[4]arene bis-bithiophene) by the examination of the structure and dynamics of the dichloromethane solvent around the calix[4]arene units. (6) Investigation of the selectivity of a polythiophene functionalized with calix[4]arene nanosensor at the microscopic level which experimentally presents a great selectivity towards Na+ with respect to K+ and Li+ alkaline cations.
