Kavli Affiliate: Shmuel M. Rubinstein | First 5 Authors: Jovana Andrejevic, Lisa M. Lee, Shmuel M. Rubinstein, Chris H. Rycroft, | Summary: As a confined thin sheet crumples, it spontaneously segments into flat facets delimited by a network of ridges. Despite the apparent disorder of this process, statistical properties of crumpled sheets exhibit striking reproducibility. […]
Kavli Affiliate: Robert J. Wood | First 5 Authors: Kaushik Jayaram, Jennifer Shum, Samantha Castellanos, E. Farrell Helbling, Robert J. Wood | Summary: Here we present HAMR-Jr, a SI{22.5}{millimeter}, SI{320}{milligram} quadrupedal microrobot. With eight independently actuated degrees of freedom, HAMR-Jr is, to our knowledge, the most mechanically dexterous legged robot at its scale and is […]

Kavli Affiliate: Daniel Needleman | First 5 Authors: Joonhee Choi, Hengyun Zhou, Renate Landig, Hai-Yin Wu, Xiaofei Yu | Summary: Understanding the coordination of cell division timing is one of the outstanding questions in the field of developmental biology. One active control parameter of the cell cycle duration is temperature, as it can accelerate or […]
Kavli Affiliate: Joanna Aizenberg | First 5 Authors: Giulia Magnabosco, Iryna Polishchuk, Francesco Palomba, Enrico Rampazzo, Luca Prodi | Summary: Inclusion of additives into calcite crystals allows one to embed non-native proprieties into the inorganic matrix and obtain new functional materials. Up to now, few parameters have been taken into account to evaluate the efficiency […]
Kavli Affiliate: Michael Brenner | First 5 Authors: Subhashini Venugopalan, Arunachalam Narayanaswamy, Samuel Yang, Anton Geraschenko, Scott Lipnick | Summary: Confounding variables are a well known source of nuisance in biomedical studies. They present an even greater challenge when we combine them with black-box machine learning techniques that operate on raw data. This work presents […]
Kavli Affiliate: Vinothan Manoharan | First 5 Authors: Brian Leahy, Ronald Alexander, Caroline Martin, Solomon Barkley, Vinothan Manoharan | Summary: Holographic microscopy has developed into a powerful tool for 3D particle tracking, yielding nanometer-scale precision at high frame rates. However, current particle tracking algorithms ignore the effect of the microscope objective on the formation of […]
Kavli Affiliate: Anna V. Shneidman | First 5 Authors: Alireza Shahsafi, Graham Joe, Soeren Brandt, Anna V. Shneidman, Nicholas Stanisic | Summary: Engineered optical absorbers are of substantial interest for applications ranging from stray light reduction to energy conversion. We demonstrate a large-area (centimeter-scale) metamaterial that features near-unity frequency-selective absorption in the mid-infrared wavelength range. […]
Kavli Affiliate: Robert J. Wood | First 5 Authors: Neel Doshi, Kaushik Jayaram, Samantha Castellanos, Scott Kuindersma, Robert J Wood | Summary: Limitations in actuation, sensing, and computation have forced small legged robots to rely on carefully tuned, mechanically mediated leg trajectories for effective locomotion. Recent advances in manufacturing, however, have enabled the development of […]
Kavli Affiliate: Radhika Nagpal | First 5 Authors: Daniel S. Calovi, Paul Bardunias, Nicole Carey, J. Scott Turner, Radhika Nagpal | Summary: Termite colonies construct towering, complex mounds, in a classic example of distributed agents coordinating their activity via interaction with a shared environment. The traditional explanation for how this coordination occurs focuses on the […]
