    Following our recent observations of contraction waves in the primitive epithelium of Placozoa, we develop a model of tissues as sheets of contractile cells. The simple model assumes only a strain-threshold for contraction, and explains/predicts a variety of unique and surprising phenomena, e.g.: contraction waves in response to external stress, spontaneously-compressed steady-state, emerged limit-cycles, mechanical frustration and active resistance to rupture. In the talk I will present both the experimental observations and the model results. This model of “active cohesion” may be relevant to any epithelial tissue, to manufacturing of synthetic active materials, and to models of evolution of multicellularity.

    Brownian motion is a Gaussian process described by the central limit theorem. However, exponential decays of the positional probability density function $P(X,t)$ of packets of spreading random walkers, were observed in numerous situations that include glasses, live cells and bacteria suspensions. We show that such exponential behavior is generally valid in a large class of problems of transport in random media. By extending the Large Deviations approach for a continuous time random walk we uncover a general universal behavior for the decay of the density. It is found that fluctuations in the number of steps of the random walker, performed at finite time, lead to exponential decay (with logarithmic corrections) of $P(X,t)$. This universal behavior holds also for short times, a fact that makes experimental observations readily achievable.

    Abstract:
    In recent years, Van der Waals (2D) materials, have attracted increasing attention due to their distinctive physical properties. As layered materials, they have been considered for flexible electronics as they can sustain strain higher than 10% without breaking down, although they are only 1-3 atom thick. Their superior mechanical properties led to a renewed interest in the mechanics of thin membranes linked to condensed matter physics. In this talk we will show how we can apply non-uniform strain to a suspended Van der Waals material (WS2) and alter the dynamics of excitons and trions. Surprisingly, we find that as we increase the non-uniformity of the strain, we are able to convert the excitons into trions with almost 100% efficiency without any electrostatic gating. Our results explain inconsistencies in previous experiments and pave the way towards new types of optoelectronic devices.

    My group is addressing fundamental questions in evolutionary biology, using both genome- and phenotype-first approaches. A few years ago, we discovered that Arabidopsis thaliana is a great model for the study of hybrid necrosis. This widespread syndrome of hybrid failure in plants is caused by plant paranoia – regardless of the presence of enemies, plants “think” they are being attacked by pathogens. Over the past decade, we have studied in detail the underlying genetics, finding that often one or two loci encoding NLR immune receptors are causal. NLRs make up the most variable gene family in plants, and it is not surprising that they are often involved in genome-genome conflicts. Hybrid necrosis results when NLR genes meet that have not been co-adapted. This has in turn raised the question of the scale of NLR diversity, and our goal for the next decade is to understand the genomic and geographic patterns of immune system and especially NLR diversity. In 2018, we initiated a project, PATHO(gens in Arabi)DOPSIS, in which we aim to describe genetic diversity in the host A. thaliana and two of its important pathogens, the generalist Pseudomonas sp. and the specialist Hyaloperonospora arabidopsidis. The long-term vision is to produce maps of resistance alleles in the host, and of effector alleles in the pathogens, in order to learn when the pathogens win in a wild plant pathosystem – and when the hosts prevail.

    Detlef Weigel, a German-American scientist, is currently Executive Director of the Max Planck Institute for Developmental Biology. He is a member of the US National Academy of Sciences, the German National Academy of Sciences Leopoldina and the Royal Society, and recipient of several scientific awards.
    The first major finding from his lab was that an Arabidopsis gene could dramatically accelerate flowering of trees; this established a proof of concept for Arabidopsis genetics as a platform for biotechnological discoveries. His group later discovered the first plant microRNA mutant and identified the factor that we now know to be the long sought-after mobile flower-inducing signal. Detlef was also one of the first to exploit natural genetic variation for understanding how the environment affects plant development. In recent years, this work has come to incorporate questions at the interface of evolution and ecology: How can wild plants adapt to climate change, and how do they manage to keep their pathogens at bay? In addition to hypothesis-driven research, his group has a long history of providing new technologies and resources to the community. This has culminated in a collaborative effort to sequence the genomes of over 1,000 natural A. thaliana strains (The 1001 Genomes Project).
    Detlef has an extensive record of service to the scientific community, having served on a series of editorial and advisory boards. He is a forceful advocate of open access publishing and founding Deputy Editor of eLife. He is a co-founder of three biotech startups.
