Department of Science Teaching
Overview
The Department of Science Teaching main interrelated missions are to advance the academic discipline of science and mathematics education, to enhance the quality and effectiveness of mathematics and science education in Israel, and to develop academic and practical leadership in science and mathematics education in Israel and overseas. The Department carries out educational research and development primarily for grades 7-12 in mathematics, physics, chemistry, computer science, earth sciences and life sciences, and in science and technology for junior high school. The Department targets both the general student population and those who are majoring in one or more of these disciplines. The Department carries out interrelated and continuous long-term academic activities, including research, development and implementation of innovative learning materials, pedagogical models, and teachers' professional development (PD). The Department has many avenues of collaboration with other departments on campus and with the educational system in Israel; it has a significant impact on science education research, practice, and policy in Israel and overseas.
As the Department is currently shifting from mainly textual teaching and learning materials developed in the Department to primarily digital platforms, the demand for techno-pedagogical support has increased tremendously in recent years. This shift allows the incorporation of new methodologies for both teaching and learning, as well as in the way research is carried out in the Department. The large amount of data on teachers’ and students’ performance accumulating in databases promote the development and use of new research methodologies. AI tools are currently being developed to improve both the teaching and learning that take place on these platforms, as well as to expand the Department’s research possibilities. These days Department is establishing a core facilities unit, entitled EduCore, that is expected to provide the needed services (e.g., software development, technological design, data science services, etc.) and to support both research and development in the various research groups, as well as other units and faculties at the Weizmann Institute that are in need of techno-pedagogical services.
Department of Plant and Environmental Sciences
Overview
Plants offer the world its only renewable resource of foods, alternative energy and biotherapeutic compounds. Plants have highly sophisticated short and long-term adaptive mechanisms to the environment as a result of the simple fact that they cannot alter their location during environmental change. Basic understanding of how plants react to the environment and why they grow the way they do are central to devising a rational approach to address three important global challenges, namely to secure more and healthier food, to develop novel plant-based products associated with biotherapeutics and to produce alternative energy resources in the form of biofuels. Research activities in the Department of Plant Sciences are associated with all of the above-mentioned global challenges and range from studies on the function and regulation of isolated genes to their interactive behavior in the context of the whole plant. We have developed extensive in-house genomic, bioinformatics and transgenic infrastructure that enables us to isolate novel genes by gene trapping, knockout or map-based cloning. Cloned genes are manipulated and studied by transgenic analysis to establish their potential in the whole plant. Our research as listed below integrates methodologies of molecular biology, protein modeling, genomics, metabolomics, bioinformatics, system biology, genetics, biochemistry and physiology.
Harnessing light energy and energy transduction in the plant cell: Research is carried out on the basic biophysical phenomenon of photon absorption by chlorophyll through transduction of this energy to ATP and the regulation of energy flux by the plant redox state.
Adaptive response in the plant to the biotic and abiotic environment: Molecular mechanisms that drive the cellular response are investigated under environmental perturbation. Research is directed in understanding the elements that play a role in the recognition of pathogens and the subsequent mounting of plant defense responses as well as in the response of plants to abiotic stresses, such as salt stress.
Plant metabolism and growth: Research is centered around elucidating regulatory metabolic networks for production of essential primary and secondary metabolites as well as understanding gene expression and hormonal networks that control plant metabolism, growth, reproduction and productivity.
Plant genome organization: Molecular tools have been developed to examine the fluidity of the plant genome, as described by transposon element, and the evolution of polyploid plants.
Department of Physics of Complex Systems
Overview
The Department of Physics of Complex Systems pursues two main directions, Atomic, Molecular and Optical (AMO) physics and the physics of Soft and Biological Matter. Contemporary topics in AMO physics range from atto-second pulses and intense lasers, through precision spectroscopy of ultracold atoms, molecules or ions, to quantum information and quantum optics. Soft and biological physics are characterized by wide ranging complexity that can often be simplified by considering fundamental physical concepts and principles. The Department consists of slightly under 20 groups, of which about two thirds are experimentalists and one third are theoreticians.
Atomic, Molecular and Optical Physics
The AMO groups in the Department of Physics of Complex Systems study a wide variety of topics in nonlinear and quantum optics, atomic and molecular physics. Of interest are the properties of atoms and ions at ultra-cold temperatures where full control of individual atoms and photons is possible and quantum phenomena are manifested. These unique properties can be applied for quantum sensing, simulations and computing and study of new physics. Both theoretical and experimental aspects of Quantum Computation comprise an important and very significant goal of the research.
A particularly rich field of study is that of the interaction of ultrashort optical pulses with atoms, molecules, electrons and solids, which enables the measurement of ultrafast dynamics, allows the acceleration of electrons and protons, and generates new radiation sources for bio-medical applications. In addition, investigations of the geometrical quantum nature of light are conducted, along with its use for simulating general relativity in the lab.
Soft Matter and Biological Physics
The theoretical issues in soft matter cover non-equilibrium processes and aspects of emergent properties, of frustration and of material structure, all of which can be approached using the tools of statistical mechanics coupled with a deep mathematical description of organization in matter. Structures in liquid and organic crystals, as well as in viscoelastic material yield insight on the underlying physical processes and mechanisms. In biological systems, mechanisms that determine the size of cells can be obtained using physics modeling and theoretical concepts. In considering the statistical physics of turbulence, special emphasis is made on broken and emerging symmetries, with important implications for conformal invariance in inverse turbulent cascades and recently for the kinetic and hydrodynamic theory of emerging viscous electronics.
The experimental labs treat such diverse systems as ants, single molecules, neuronal cultures, one dimensional organisms, and even human groups. A unifying theme lies in relating the properties of the constituent parts to those of the emerging whole. Biological computation is treated in social contexts such as ant colonies and in devices comprised of living neurons. Emergent properties such as synchronization of activity, decision making and resource sharing are among the novel phenomena that have been discovered in these systems. Turbulence in viscoelastic media is studied in microfluidic environments.

The molecular basis of genetics and related biological processes are under investigation in our Department. The investigators approach these processes from the most reduced and reconstructed systems up to more systemic and computational analysis. Different organisms are employed including virus, yeast, Drosophila, mouse and human. These animal models and cell culture systems are used to study the mechanisms of;
a. Basic processes in gene expression, such as transcription, translation and protein degradation.
b. Cellular responses to various stimuli, such as cytokines, growth factors and exposure to DNA-damage.
c. Regulation of cell growth, senescence, differentiation and death.
d. Development; Mechanistic view of zygote to embryo transition and development of various organs, such as brain, muscles, bones and pancreas.
e. Genetic and acquired diseases such as cancer and virus infection. Embryonic stem cell biology, early development and advance human disease modeling.

Department of Materials and Interfaces
Overview
Activities in the Department span a wide range of topics from soft, composite and hard materials to energy research, nanoscience, and biological materials. A unifying theme is the study of material functionality and its relation to fundamental properties at multiple scales. These properties may be mechanical, structural, chemical, electronic, magnetic, optical, and more. Some examples are:
How do shapes and sizes of nm-sized particles affect their properties?
How can we tune the properties of solar cells by manipulating their material interfaces?
How does friction in knee and hip joints depend on polyelectrolytes that lubricate them?
How can we design self-assembling (bio)chemical systems?
THE RESEARCH IS BASED ON AN INTERDISCIPLINARY APPROACH, and indeed the scientists bring complementary experience in chemistry and physics, including both theory and experiment.
