Mechano-transduction: from molecules to tissues. [PDF]
External forces play complex roles in cell organization, fate, and homeostasis. Changes in these forces, or how cells respond to them, can result in abnormal embryonic development and diseases in adults.

Cryo-EM captures early ribosome assembly in action
The production of ribosomes is a precisely orchestrated energy consuming cellular process of highest priority. Here, the authors use cryo-EM to show that bacterial ribosomal subunits, self-assembled from their purified RNA and protein components, mature ...

Information processing and signal integration in bacterial quorum sensing
Bacteria communicate using secreted chemical signaling molecules called autoinducers in a process known as quorum sensing. The quorum‐sensing network of the marine bacterium Vibrio harveyi uses three autoinducers, each known to encode distinct ecological

Biophysics at the coffee shop: lessons learned working with George Oster [PDF]
Over the past 50 years, the use of mathematical models, derived from physical reasoning, to describe molecular and cellular systems has evolved from an art of the few to a cornerstone of biological inquiry.

Using mass spectrometry imaging to visualize age-related subcellular disruption
Metabolic homeostasis balances the production and consumption of energetic molecules to maintain active, healthy cells. Cellular stress, which disrupts metabolism and leads to the loss of cellular homeostasis, is important in age-related diseases.

Dorsoventral patterning of the Xenopus eye involves differential temporal changes in the response of optic stalk and retinal progenitors to Hh signalling [PDF]
Background: Hedgehog (Hh) signals are instrumental to the dorsoventral patterning of the vertebrate eye, promoting optic stalk and ventral retinal fates and repressing dorsal retinal identity.

Evaluation of Pharmacological Rescue of Melanocortin-4 Receptor Nonsense Mutations by Aminoglycoside
The melanocortin-4 receptor (MC4R) is critical for central satiety regulation, therefore presenting a potent target for pharmacological obesity treatment. Melanocortin-4 receptor mutations prevalently cause monogenetic obesity.
