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.

The alarming omnipresence of microplastics in rivers, lakes, and oceans increasingly gains the critical focus of research. So far, however, there has been no reliable knowledge as to whether microplastic particles in aquatic ecosystems promote the development of special bacterial communities or even the spread of pathogens. A recent study within the project MikrOMIK* headed by the Leibniz Institute for Baltic Sea Research Warnemünde (IOW) has now for the first time systematically investigated whether bacterial biofilms on microplastic particles differ from those on natural materials and how various environmental factors such as salinity or nutrients influence the community composition.
Today, microplastics – plastic particles smaller than 5 millimetres – can be detected everywhere in the environment. Many hundreds of thousands particles per...05.04.2018 | Read more

Global warming affects more than just plant biodiversity - it even alters the way plants grow. A team of researchers at Martin Luther University Halle-Wittenberg (MLU) joined forces with the Leibniz Institute for Plant Biochemistry (IPB) to discover which molecular processes are involved in plant growth. In the current edition of the internationally renowned journal "Current Biology", the group presents its latest findings on the mechanism controlling growth at high temperatures. In the future this could help breed plants that are adapted to global warming.
Plants react much more sensitively to fluctuations in temperature than animals. They are also unable to seek out warmer or cooler locations. "When temperatures...12.01.2018 | Read more

Forests fulfil numerous important functions, and do so particularly well if they are rich in different species of trees. This is the result of a new study. In addition, forest managers do not have to decide on the provision of solely one service – such as wood production or nature conservation – as a second study demonstrates: several services provided by forest ecosystems can be improved at the same time. Both studies were led by scientists from Leipzig University and the German Centre for Integrative Biodiversity Research (iDiv), and published in the prestigious journal Ecology Letters.
Forests are of great importance to humans: the wood grown in forests is used in our houses for furniture, roof timbers and flooring; forests store carbon from...17.11.2017 | Read more

Researchers from the Department of Atomically Resolved Dynamics of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg, the University of Potsdam (both in Germany) and the University of Toronto (Canada) have pieced together a detailed time-lapse movie revealing all the major steps during the catalytic cycle of an enzyme. Surprisingly, the communication between the protein units is accomplished via a water-network akin to a string telephone. This communication is aligned with a ‘breathing’ motion, that is the expansion and contraction of the protein.
This time-lapse sequence of structures reveals dynamic motions as a fundamental element in the molecular foundations of biology.

A supersolid is a state of matter that can be described in simplified terms as being solid and liquid at the same time. In recent years, extensive efforts have been devoted to the detection of this exotic quantum matter. A research team led by Tilman Pfau and Tim Langen at the 5th Institute of Physics of the University of Stuttgart has succeeded in proving experimentally that the long-sought supersolid state of matter exists. The researchers report their results in Nature magazine.
In our everyday lives, we are familiar with matter existing in three different states: solid, liquid, or gas. However, if matter is cooled down to extremely...
A team headed by Prof. Steve Albrecht from the HZB will present a new world-record tandem solar cell at EU PVSEC, the world's largest international photovoltaic and solar energy conference and exhibition, in Marseille, France on September 11, 2019. This tandem solar cell combines the semiconducting materials perovskite and CIGS and achieves a certified efficiency of 23.26 per cent. One reason for this success lies in the cell’s intermediate layer of organic molecules: they self-organise to cover even rough semiconductor surfaces. Two patents have been filed for these layers.
Perovskite-based solar cells have experienced an incredibly rapid increase in efficiency over the last ten years. The combination of perovskites with classical...
