But other researchers see evidence for prokaryotic cells in the first 100 million years, maybe even immediately. "...Actual cells have been found in the earth's oldest unmetamorphosed sediments...," says Gould in . Bada says that cyanobacteria may have emerged only ten million years after the first precellular life . In November, 1996, S. J. Mojzsis of the Scripps institution of Oceanography and others reported isotopic evidence that cellular metabolism was under way before 3.8 billion years ago . Even before the research by Mojzsis , Francis Crick was worried by the time problem. "...The real fossil record suggests that our present form of protein based life was already in existence 3.6 billion years ago.... This leaves an astonishingly short time to get life started" . Another researcher, Yale biochemist Peter B. Moore, says this about the time problem :

Photovoltaic Properties of New Cyanine-Naphthalimide Dyads Synthesized by 'Click' Chemistry.

Elio Giamello is active, since the early eighties, in the field of Chemistry and Surface Chemistry of metal oxides with particular emphasis on the applications of Electron Paramagnetic Resonance spectroscopy (EPR) to this field. Focus of his interest are the paramagnetic centres at the surface (surface defects, reactive intermediates, transition metal centres) and in the bulk of bare oxides, doped oxides and mixed oxides. Such centres are investigated in order to better understand their role in determining the chemical properties (e.g. chemisorption, catalysis), the magnetic properties and the optical properties of the material. A peculiar attention in recent years has been devoted to the problem of visible light harvesting by doped semiconductors in order to allow the use of solar light in photocatalysis.

Medicinal chemist of the University of Minnesota, Twin Cities, praises Hoffmeister and his coworkers for their painstaking efforts to elucidate the biosynthesis of psilocybin. “Our knowledge of the biosynthesis of fungal natural products has lagged behind our understanding of the corresponding bacterial biosynthetic pathways owing to a number of unique challenges,” Aldrich says. For instance, the genomes of fungi are more complex than bacteria, many fungi are still not amenable to genetic manipulation, and cultivating fungi to produce sufficient amounts of desired metabolites is not always straightforward. “The new work lays the foundation for developing a fermentation process for production of this powerful psychedelic fungal drug, which has a fascinating history and pharmacology,” Aldrich adds.

“The publication by Hoffmeister and colleagues highlights a terrific example of genomics-based biocatalyst-pathway discovery,” adds natural products researcher of the University of Kentucky. “While psilocybin biosynthesis derives from a series of fairly simple chemical transformations, this new study identifies the contributing genes and biocatalysts for the first time and, importantly, provides strong evidence to support a revision of the order of the key steps proposed more than five decades ago. This work clearly sets the stage for bioengineered psilocybin production and/or for analogs that may serve as compelling alternatives to existing synthetic strategies.”

Veronique started her independent research career at the University of Oxford in 1998 in the Chemistry Faculty and was promoted to Professor of Chemistry in 2008. Her research aims at developing new approaches to address long-standing problems in the synthesis of fluorinated molecules including pharmaceutical drugs and probes for imaging (Positron Emission Tomography). To date, she has mentored more than 30 Postdocs and supervised 40 PhD (= DPhil in Oxford) to completion.

Her research is mostly concerned with the study of nonlinear partial differential equations and the use of variational methods to study problems in relativistic quantum mechanics and quantum chemistry. She has also made contributions to the study of fluid-structure interaction problems and is recently interested in the understanding of symmetry and symmetry breaking phenomena in the framework of functional inequalities.

T., Chemoenzymatic synthesis of triazole-linked glycopeptides.

Professor Akiyama is a member of the Organizing Committee of the UNESCO-sponsored traveling exhibition "Experiencing Mathematics", a trustee of the Heisei Foundation of Basic Science, and chairman of the Awards Committee for the Koshiba Prize, which encourages youngsters to become creative scientists. The committee includes Nobel Prizewinners Dr. Masatoshi Koshiba (Physics) and Dr. Hideki Shirakawa (Chemistry). Professor Akiyama's recent research topics in discrete geometry have an original slant and are chosen for their applicability. The appeal of the problems lies in that they are not difficult to explain, even to non-mathematicians, and their solutions, while difficult to discover, are very elegant and fascinating. A case in point is the result in his recent paper entitled "Tile-makers and Semi-tile-makers" published in American Mathematical Monthly (Vol.114). He proves that if you take a regular tetrahedron, then no matter how you cut its surface, provided that it remains in one piece and can be lain flat on a plane, then the result is a tile which tesselates the plane.

Alan Herbert Cowley was born in Manchester, England. He was educated at the University of Manchester, England, where he received the following degrees: Bachelor of Science with Honors in Chemistry in 1955, Master of Science in 1956, and Doctor of Philosophy in 1958. He was a Postdoctoral Fellow, and later an Instructor at the University of Florida during the period 1958-1960. During the years 1960-1961 he was a Technical Officer with the Exploratory Group of Imperial Chemical Industries (Billingham Division), England. From 1962 to 1988 he was at The University of Texas at Austin, where he held the following positions: Assistant Professor of Chemistry, 1962-1967, Associate Professor of Chemistry, 1967-1970, Professor of Chemistry, 1970-1984, George W. Watt Centennial Professor of Chemistry, 1984-1988. From 1988-1989, he was the Sir Edward Frankland Professor of Inorganic Chemistry at Imperial College, London, U.K. He returned to the University of Texas at Austin in 1989 and currently holds the Robert A. Welch Chair in Chemistry.
