Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Synthesis and post-functionalization of alternate-linked-meta-para-[2n.1n]thiacyclophanes
Beilstein Journal of Organic Chemistry, 2018 In recent decades, considerable research attention has been devoted to new synthetic procedures for thiacyclophanes. Thiacyclophanes are widely used as host molecules for the molecular recognition of organic compounds as well as metals. Herein, we report

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Avian host-selection by Culex pipiens in experimental trials.
PLoS ONE, 2009 Evidence from field studies suggests that Culex pipiens, the primary mosquito vector of West Nile virus (WNV) in the northeastern and north central United States, feeds preferentially on American robins (Turdus migratorius). To determine the contribution

A medium deep Chandra and Subaru survey of the 13hr XMM/ROSAT deep survey area [PDF]
, 2003 We present the results of a Chandra ACIS-I survey of a high latitude region at 13h +38 which was earlier observed with ROSAT (McHardy et al. 1998) and which has recently been observed by XMM-Newton for 200ksec.

Phytopathogens Reprogram Host Alternative mRNA Splicing
Annual Review of PhytopathologyAlternative splicing (AS) is an evolutionarily conserved cellular process in eukaryotes in which multiple messenger RNA (mRNA) transcripts are produced from a single gene. The concept that AS adds to transcriptome complexity and proteome diversity introduces a new perspective for understanding how phytopathogen-induced alterations in host AS cause ...

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

"Retired" Planet Hosts: Not So Massive, Maybe Just Portly After Lunch
, 2011 Studies of the planet abundance as a function of stellar mass have suggested a strong increase in the frequency of planet occurrence around stars more massive than $1.5 M_\odot$, and that such stars are deficit in short period planets.
