Protein degradation governs many biological processes, but studying degradation can be technically challenging. We developed a degradation assay and a software package that overcome several of these challenges.

Synthetic DNA-based nanodevices offer tremendous promise as drug delivery capsules and diagnostic tools in living systems. In a recent perspective (Surana et al. Nat. Nanotechnol. 2015), we outline possible outcomes of the interactions between DNA nanostructures and the immune system, and envision potential design principles in these architectures to circumvent the multifaceted defense machinery of higher organisms.

Activation of GABAergic neurons in the ventral medulla can reliably induce REM sleep, the brain state associated with vivid dreaming.

Embryonic stem cells are pluripotent because they lack the ability to form extra-embryonic tissue. In contrast, totipotent cells can generate a complete organism including embryonic and extraembryonic tissues. Cells resembling totipotent 2-cell stage embryos (2C-like cells) arise at very low frequency in embryonic stem cell cultures. We showed that mouse 2C-like cells can be induced in vitro through downregulation of the chromatin-assembly activity of CAF-1.

A label-free optical microscopy technique based on Brillouin light scattering that is capable of measuring intrinsic longitudinal modulus at sub-cellular resolution has been developed. Cell mechanical properties are involved in many cell functions such as migration and differentiation, and can influence system level behavior such as tissue morphogenesis. However, current measurements of the biomechanical properties of cells generally require physical contact and thus are limited to cells cultured...

The feedback between the transport of the plant hormone auxin and the polarization of its transporters plays an essential role in the regulation of plant development. We propose biochemical networks that may implement this feedback in nature.

Despite the evolutionary role of homologous recombination in protecting genome integrity, it has not been experimentally demonstrated in the animal mitochondrial DNA (mtDNA). In the study described below, by selecting against the two parental genomes in Drosophila, progeny with only recombinant mtDNA were recovered. Recombination can occur between highly diverged mitochondrial genomes and often involves long continuous stretches of exchange. In addition, some recombinants allowed us to map a novel...

The ability of somatic stem cells to regenerate tissue is reduced with aging, resulting in effects such as cognitive impairment, reduced immune response, deterioration of skeletal muscle, and difficulty in wound healing. Using neural stem cells of the brain, the authors suggest the mechanism behind this age-dependent stem cell dysfunction is the cell's inability to segregate accumulated damage to its progeny during cell division due to a weakened diffusion barrier.

Mitotic entry in higher eukaryotes is always accompanied by fenestration of the nuclear envelope, allowing mitotic regulators to passively diffuse from the cytoplasm into the "nuclear" space and vice versa. Curiously, several of these proteins have been shown to accumulate in the "nuclear" region although a stationary binding substrate could not be identified. Our recent findings shed light on the underlying mechanism and reveal its importance for accurate cell division.

A complex interplay between different cell types is needed to ensure the efficient response of the immune system. Communication between mast cells and dendritic cells reveals an unexpected role for mast cells in modulating the immune response.
