Distinct Favored Regions for Historical Record‐Setting and Future Record‐Breaking Humid Heat

open access: yesAGU Advances
Recent studies have revealed strong trends in humid heat, including the nearing of human physiological limits in some regions. Understanding of past extremes and their meaningfulness for contextualizing future possibilities, especially in the near‐term ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Price stability and financial stability: the historical record [PDF]

open access: yes
Although the economic performance of the U.S. economy in 1997 was very good, it was troubling in at least one respect for the Federal Open Market Committee. Traditional signals of inflation - rapid money growth and high levels of economic activity - were

European Integration – Democracy Promotion by the EU in Eastern Europe [PDF]

open access: yes, 2007
There have been a few historical turning points in modern European history. The turning points of 1648, 1815, 1919 and 1945 had great impact on the developments of Europe. The last turning point of 1991 is not an exception to such record. The collapse

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS 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 ...

Errors in climate model daily precipitation and temperature output: time invariance and implications for bias correction [PDF]

open access: yes, 2013
When correcting for biases in general circulation model (GCM) output, for example when statistically downscaling for regional and local impacts studies, a common assumption is that the GCM biases can be characterized by comparing model simulations and ...
