A Biohybrid Superorganism - Investigating honeybees' collective behaviors via interactive robotics

Social insects, such as ants, termites, and honeybees, have evolved sophisticated societies where the collaborative efforts of "simple" individuals can lead to the emergence of complex dynamics. The reliance of each organism on the collective is so great t ...

An Autonomous Robotic Platform to Manipulate Collective Behavior in Ants

Matthias Rüegg

Eusocial life is characterized by division of labour, collective decision making and self organization, and regarded as the highest form of social organisation in groups. Ants are a model organism for research in collective behavior and the evolution of eu ...

Combination of dielectrophoretic and hydrodynamic traps for the controlled contact between cells or beads and application to adhesion assays

Clémentine Sophie Sarah Lipp

Multicellular organisms require very well organized and finely balanced cell-cell communication, adhesion and coordination to ensure the organisms homeostasis. These functions rely on specialized receptors placed at the cells membrane whose binding to thei ...

Material Substrate Physical Properties Control Pseudomonas aeruginosa Biofilm Architecture

Alexandre Louis André Persat, Alice Cont

The biofilm lifestyle is the most widespread survival strategy in the bacterial world. Pseudomonas aeruginosa biofilms cause chronic infections and are highly recalcitrant to antimicrobials. The genetic requirements allowing P. aeruginosa to grow into biof ...

Robotic manipulation to investigate the physical principles of biological self-organization

Fazil Emre Uslu

Self-organization is the spontaneous formation of ordered patterns and networks from a population of comparatively simple elements or individuals with no prior information on neither the formation process nor the final organization. While the construction ...

Nanomotion Detection-Based Rapid Antibiotic Susceptibility Testing

Sandor Kasas, María Inés Villalba, Anton Malovichko

Rapid antibiotic susceptibility testing (AST) could play a major role in fighting multidrug-resistant bacteria. Recently, it was discovered that all living organisms oscillate in the range of nanometers and that these oscillations, referred to as nanomotio ...

The social nature of mitochondria: Implications for human health

Maria del Carmen Sandi Perez

Sociality has profound evolutionary roots and is observed from unicellular organisms to multicellular animals. In line with the view that social principles apply across levels of biological complexity, a growing body of data highlights the remarkable socia ...

A perspective view on the nanomotion detection of living organisms and its features

Giovanni Dietler, Sandor Kasas, Anne-Céline Verenna Kohler, María Inés Villalba, Petar Stupar, Giovanni Longo, Leonardo Venturelli, Massimiliano Bertacchi

The insurgence of newly arising, rapidly developing health threats, such as drug-resistant bacteria and cancers, is one of the most urgent public-health issues of modern times. This menace calls for the development of sensitive and reliable diagnostic tool ...

Integrin-Mediated Adhesion in the Unicellular Holozoan Capsaspora owczarzaki

Omaya Pierre Dudin

In animals, cell-matrix adhesions are essential for cell migration, tissue organization, and differentiation, which have central roles in embryonic development [1-6]. Integrins are the major cell surface adhesion receptors mediating cell-matrix adhesion in ...

Dispersal limitations and historical factors determine the biogeography of specialized terrestrial protists

Edward Mitchell, Luca Bragazza, Mariusz Lamentowicz, Enrique Lara, Bertrand Fournier

Recent studies show that soil eukaryotic diversity is immense and dominated by micro-organisms. However, it is unclear to what extent the processes that shape the distribution of diversity in plants and animals also apply to micro-organisms. Major diversif ...
