In the 1970’s she was the pioneer of the molybdenum cluster chalcohalides synthesized at high temperature. She has structurally characterized the first Mo4 tetrahedral cluster chalcohalides, and more recently, derived from these previous works, she obtained the first type-II-clathrate giant framework built from a molybdenum metal cluster. She has isolated the first families of Mo6 chalcohalides in which the progressive replacement of halogen ligands by chalcogen ones allows to reduce the dimensionality and to control the strengthening of intercluster interactions giving several series going from insulators with dielectric relaxations and dipole glass behaviour to semi-conductors and to metallic conductors with superconducting transitions. Theoretical calculations accompanied these structural works to study the metal-metal and metal-ligand bonding and to explain their physical properties.

Prof. Imamoglu received his Ph.D from Stanford University with a dissertation on electromagnetically induced transparency and lasers without inversion. After postdoctoral stays at NTT Basic Research Laboratories in Tokyo, Japan and at the Institute of Theoretical Atomic and Molecular Physics at Harvard University in Cambridge, Massachusetts, he joined The University of California at Santa Barbara as an Assistant Professor in 1993. He was promoted to Associate Professorship in 1997 and to full Professorship in 1999. Prof. Imamoglu has pioneered the use of quantum dots in study of quantum optical phenomena. In particular, his group demonstrated the first quantum dot single photon source, the Purcell effect in quantum dot cavity-QED, and the use of photon correlation spectroscopy to understand quantum dot physics. Hiss current research interests include the study of strongly correlated systems using quantum optical techniques.

Included are sciences such as mineralogy, geodesy, and stratigraphy

Growing the human brain was about more than energy. There is speculation that meat protein helped human evolutionary brain development, and there is also evidence that oils help. There are surely nutritional requirements besides calories, but calories comprise the vast majority of nutrition. About 80% of what is called human nutrition consists of calories. If animals can obtain enough energy, the other dietary constraints are usually minor issues.

A plausible series of events, when fire came first and Acheulean industry second, is that the that traveled to East and Southeast Asia did not have Acheulean tools, but the primitive Oldowan toolset, and . I consider it quite possible that early migrated from Africa (and maybe even an earlier protohuman, if the “” were descended from habilines or australopiths) wielding fire. Cooking came with it, and hundreds of thousands of years later, those that stayed home in cosmopolitan Africa invented a new level of technology, Acheulean tools, and that culture never made it to the remote corners of East Asia. Some have speculated that those East Asian used bamboo more than stone, which would not be preserved for study today, or that as they moved east they lost the art of making Acheulean tools. I think the likelier explanation is that they had Acheulean tools, which means that they left Africa before they were invented, but they brought fire with them, which was the essential technology.

Katharina M. Fromm is Full Professor for Inorganic Chemistry at the Department of Chemistry of the bilingual University of Fribourg since 2006. After having been President of the Chemistry Department and Director of the Fribourg Center for Nanomaterials (FriMat), she was (re-)elected as a Research Councilor of the Swiss National Science Foundation as of 2011 for eight years. In 2015, she became President of the Division “Programmes” of the Swiss National Science Foundation, and as of 2016 Vice-President of the Research Council. She has also been elected as the first Fellow of the American Chemical Society in Europe, is member of the Platform Chemistry of the Swiss Academy of Sciences and acts as mentor to a group of young talents via the Swiss Study Foundation. Her research interests emerge from the coordination chemistry of alkali, alkaline earth and transition metal elements via antimicrobial properties of silver compounds to nanoparticles and nanorattles for batteries and implants. A current focus lies on the bioinorganic chemistry of silver, as well as silver resistance and biomineralisation mechanisms by bacteria. Furthermore, she is active in public outreach activities and pushing the MINT areas.

This essay is intended to draw a comprehensive picture of life on Earth, the human journey, and energy's role. The references that support this essay are usually to works written for non-scientists or those of modest academic achievement so that non-scientists can study the same works without needing specialized scientific training. I am trying to in a tiny fraction of the global population. . My hope is that the energy issue can become that tiny fraction's focus. Properly educated, that group might be able to help catalyze an energy effort that can overcome the obstacles. That envisioned group may help humanity in many ways, but my primary goal is manifesting those technologies in the public sphere in a way that nobody risks life or livelihood. I have seen too many wrecked and prematurely ended lives (, ) and plan to avoid those fates, for both myself and the group’s members.

Another major advance happened in the late 20th century: the ability to analyze DNA. was discovered in 1953. In 1973, . In 2003, . was accomplished in 2005, for orangutans in 2011, and for in 2012. The comparisons of human and great ape DNA have yielded many insights, but the science of DNA analysis is still young. What has yielded far more immediately relevant information has been studying human DNA. The have been identified. Hundreds of falsely convicted Americans have been released from prison, and nearly 20 from , due to Human DNA testing has provided startling insights into humanity's past. For instance, in Europe it appears that after the ice sheets receded 16,000 to 13,000 years ago, , and for all the bloody history of Europe over the millennia since then, there have not really been mass population replacements in Europe by invasion, migration, genocide, and the like. Europeans just endlessly fought each other and honed the talents that helped them conquer humanity. There were , but other than hunter-gatherers being displaced or absorbed by the more numerous agriculturalists, there do not appear to be many population replacements. In 2010, suggested that male farmers from the Fertile Crescent founded the paternal line for most European men as they mated with the local women. DNA testing has demonstrated that all of today’s humans are , of whom a few hundred and conquered Earth. The , as well as genomes of other extinct species, and for a brief, exuberant moment, some scientists thought that , -style. Although dinosaur DNA is unrecoverable, organic dinosaur remains been recovered, and even some proteins have been sequenced, which probably no scientist believed possible in the 1980s.

His major contributions to the molecular recognition field comprise the unravelling of the molecular basis of the recognition of ligands (glycans & small molecules, carbohydrate mimics) by receptors in solution, using a multidisciplinary approach, which employs organic synthesis, protein biochemistry and molecular biology, biophysics, molecular modeling, and NMR, using a wide network of collaborations worldwide. In this context, he has achieved major developments of general methodological aspects of NMR and, particularly, in its applications to the study of the dynamic features of molecular recognition processes involving sugars and proteins. The first NMR-based lectin-glycan structure was unravelled in his lab. From the drug discovery perspective, he has systematically scrutinized the employment of glycomimetics (C-, S-, N-glycoside analogues) as sugar analogues.

His research activity is mainly focused on the development and application of ab initio methods for the study of complex molecules and materials containing metals. His most significant results were obtained in the field of non-linear optics, organic light emitting diodes and dye-sensitized solar cells. Recently he switched to the study of metal-halide perovskites and of the related solar cells.
