Studies and analyses are vital to progress and innovation and are the only way to empirically verify theories.
Not all fields of science are dependent on empirical studies and analyses to verify a thesis. Mathematics, theology, philosophy and law are examples of fields that revolve within a stand-alone world in which new findings are derived by means of logical operations consisting of axioms, postulates or articles of faith (theology) that need not be proven true or accurate through empirical studies or analyses. Although these subjects are indispensable when it comes to basic research, by themselves they don't yield technical advances.
Empirical scientific approaches are diametrically opposed to these fields however. In this case, new theories are developed based on thought processes, observations and speculation. Ensuring that this knowledge has actual scientific relevance requires that it undergo an empirical evaluation however. Researchers rely on studies and analyses to compare these theses with real observations. New scientific knowledge is considered valid only after empirical studies and analyses show that theory and reality coincide. In the process it is imperative that the studies and analyses always produce the same result under the same experiment structure. Only then it is empirically proven that the result actually behaves in line with the theory.
The validation process for new findings based on studies and analyses as described above is in no way limited to natural and engineering sciences such as physics, biology, chemistry, medicine and health, machine engineering or aero and space engineering. In fields such as the social sciences, studies and analyses are also indispensable for empirically proving the accuracy of assumptions and conclusions. Sociology uses empirical-based statistics, studies and analyses to determine if statements about the migration behavior of specific population groups is accurate for instance. The field of psychology also relies on analyses and studies to empirically validate the assumptions of certain behavior patterns.
Before the Enlightenment changed our way of thinking, universities tended to postulate and speculate more than perform scientific research. Innovations therefore were apt be accidental. Once researchers were convinced that scientific results were only possible through the use of empirical studies and analysis, the groundwork was laid for the rapid advances in science that followed. Empirical studies and analyses range from simple experiments, particularly by measuring, weighing and counting, to extremely complex processes that require an enormous amount of time and money. Determining the validity of scientific theories using empirical assurances is one of the prerequisites for implementing these theories in practice. When a specific fact has been confirmed and documented based on studies and analyses, the assumption is that it will remain a fact in the future under the same premises. Only then does it make sense to develop new technologies based on this knowledge, because this provides sufficient proof of the assumption that they always function in the same manner.
Gregor Mendel's studies and analyses on genetics provided empirical proof of his theories of heredity, which then led to modern plant breeding and the establishment of food security for millions of people. The effectiveness of penicillin, another invaluable innovation for mankind, was empirically proven by Alexander Fleming through medical studies and analyses.

Researchers at the Cells-in-Motion Cluster of Excellence at Münster University have discovered that curvatures of cell membranes trigger a self-organising system. As a result, cells can move in the same direction over a longer distance, forming search patterns. The study has been published in the journal “Nature Physics”.
When an individual cell is placed on a level surface, it does not keep still, but starts moving. This phenomenon was observed by the British cell biologist...07.05.2019 | Read more

In combination with conventional statistical methods, artificial intelligence (AI) has now been used in a study of risk factors in type 1 diabetes. The objective was to identify the most important indicators of elevated risk for cardiovascular disease and death.
“What’s unique about this study is that we’ve included machine learning analyses — that is, algorithms for AI — to assess strength of association for...06.03.2019 | Read more
In a new study, a team of researchers around Alexander Winkler and Prof Victor Brovkin from the department “The Land in the Earth system” at the Max Planck Institute for Meteorology (MPI-M) show that most Earth system models (ESM) underestimate the response of Arctic plant productivity to rising atmospheric carbon dioxide (CO2) concentration.
These models, which serve as the scientific basis for the IPCC Assessment Reports, likely also underestimate future carbon uptake by photosynthesis - a key...21.02.2019 | Read more

From June 25th to 27th 2019, the Fraunhofer Institute for Digital Media Technology IDMT in Ilmenau (Germany) will be presenting a new solution for acoustic quality inspection allowing contact-free, non-destructive testing of manufactured parts and components. The method which has reached Technology Readiness Level 6 already, is currently being successfully tested in practical use together with a number of industrial partners.
Reducing machine downtime, manufacturing defects, and excessive scrap
The quality of additively manufactured components depends not only on the manufacturing process, but also on the inline process control. The process control ensures a reliable coating process because it detects deviations from the target geometry immediately. At LASER World of PHOTONICS 2019, the Fraunhofer Institute for Laser Technology ILT will be demonstrating how well bi-directional sensor technology can already be used for Laser Material Deposition (LMD) in combination with commercial optics at booth A2.431.
Fraunhofer ILT has been developing optical sensor technology specifically for production measurement technology for around 10 years. In particular, its »bd-1«...

Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.
Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...
