Weak thermal fluctuations impede steering of chiral magnetic nanobots Open
External fields are used for remote engineless and fuel-free steering of synthetic colloids. One promising method relies on spinning shaped (e.g., chiral) microbots by a rotating magnetic field, resulting in their propulsion due to viscous…

Profilin 1 controls a microglial cytoskeleton checkpoint to prevent senescence and premature synaptic decline Open
Profilin 1 (Pfn1) expression decreases significantly in aged human microglia, suggesting that loss of cytoskeletal integrity may trigger microglial senescence and increased synaptic vulnerability. To test this hypothesis, we used an induci…

Continuous Recovery of Phase from Single Interferogram Open
A new method for phase recovery from a single two-beam interferogram is presented. Conventional approaches, relying on trigonometric inversion followed by phase unfolding and unwrapping, are hindered by discontinuities typically addressed …

Torque-driven superparamagnetic microbots Open
Actuation powered by a rotating magnetic field is a promising method of controlled steering of micro(nano)metric synthetic propellers through fluids. Such actuation relies on a magnetic torque, which is a product of the driving field and a…

Positional information modulates transient regeneration-activated cell states during vertebrate appendage regeneration Open
Injury is common in the life of organisms. Because the extent of damage cannot be predicted, injured organisms must determine how much tissue needs to be restored. Although it is known that amputation position affects the regeneration spee…

A new direct method of continuous unwrapping phase from a single interferogram Open
A new method recovers the phase difference of interfering wavefronts from a pattern of interference fringes, avoiding the phase discontinuity problem. The method relies on the numerical solution of one-dimensional first-order ordinary diff…

Modeling the evolution of <i>Schizosaccharomyces pombe</i> populations with multiple killer meiotic drivers Open
Meiotic drivers are selfish genetic loci that can be transmitted to more than half of the viable gametes produced by a heterozygote. This biased transmission gives meiotic drivers an evolutionary advantage that can allow them to spread ove…
