متن کاملA proteasome for all occasions.
In the ubiquitin-proteasome system, substrates fated for destruction first acquire covalent modification by ubiquitin, and are subsequently destroyed by the proteasome. Traditionally, 26S proteasomes have been seen as largely uniform in their composition and functional capacity. Accordingly, cells can control proteasome abundance via transcriptional pathways that mediate concerted regulation of...
متن کاملA Receptor for All Occasions
Cells communicate with their environment, in part, through cell surface receptors. Engineering receptors that both sense arbitrary inputs and provide outputs orthogonal to endogenous signaling pathways has been a challenge. Now, Lim and colleagues report a system based on synthetic Notch receptors that allows independent control of both inputs and outputs in diverse cell types.

Mortality among Chinese (n = 1288) dips by 35.1% in the week before the Harvest Moon Festival and peaks by the same amount (34.6%) in the week after.

OBJECTIVE Our objective was to examine meal-patterning trends [meals and snacks, termed eating occasions (EOs)] in a sample of US children and adults. DESIGN This was a nationally representative cr...
