Algebraic Depletion Interactions in Two-Temperature Mixtures
The phase separation that occurs in two-temperature mixtures, which are driven out of equilibrium at the local scale, has been thoroughly characterized, but much less is known about the depletion interactions that drive it. Using numerical (...)

Parallel development of social behavior in biological and artificial fish
Our algorithmic understanding of vision has been revolutionized by a reverse engineering paradigm that involves building artificial systems that perform the same tasks as biological systems. Here, we extend this paradigm to social behavior. We (...)

The glass transition in molecules, colloids and grains: universality and specificity
We highlight certain key achievements in experimental work on molecular, colloidal and granular glassformers. This short review considers these three classes of experimental systems and focusses largely on the work of the authors and their (...)

Viscous tweezers: Controlling particles with viscosity
control of particle motion is generally achieved by applying an external field that acts directly on each particle. here, we propose a global way to manipulate the motion of a particle by dynamically changing the properties of the fluid in which (...)

Harnessing DNA computing and nanopore decoding for practical applications: from informatics to microRNA-targeting diagnostics
DNA computing represents a subfield of molecular computing with the potential to become a significant area of next-generation computation due to the high programmability inherent in the sequence-dependent molecular behaviour of DNA. Recent (...)

Design principles, growth laws, and competition of minimal autocatalysts
The difficulty of designing simple autocatalysts that grow exponentially in the absence of enzymes, external drives or ingenious internal mechanisms severely constrains scenarios for the emergence of evolution by natural selection in chemical (...)

Tuning collective actuation of active solids by optimizing activity localization
Active solids, more specifically elastic lattices embedded with polar active units, exhibit collective actuation when the elasto-active feedback, generically present in such systems, exceeds some critical value. The dynamics then condensates on (...)

Darwinian Evolution of Self-Replicating DNA in a Synthetic Protocell
Replication, heredity, and evolution are characteristic of Life. We and others have postulated that the reconstruction of a synthetic living system in the laboratory will be contingent on the development of a genetic self-replicator capable of (...)

Dynamics of Active Defects on the Anisotropic Surface of an Ellipsoidal Droplet
We investigate the steady state of an ellipsoidal active nematic shell using experiments and numerical simulations. We create the shells by coating microsized ellipsoidal droplets with a protein-based active cytoskeletal gel, thus obtaining (...)

Studies on V-Formation and Echelon Flight Utilizing Flapping-Wing Drones
V-Formation and echelon formation flights can be seen used by migratory birds throughout the year and have left many scientists wondering why they choose very specific formations. Experiments and analytical studies have been completed on the (...)
