Two decades of fires in the Brazilian Amazon and the differences in patterns between open and forest vegetation [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information SciencesThis study investigated the pattern distribution of fires in the Brazilian Amazon and their relationship with deforested areas from 2003 to 2022. The primary objective was to analyze fire spots’ spatial and temporal variation.

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.

Medical Benefits from Space Research [PDF]
The American Journal of Nursing, 1974 The United States space program has resulted in numerous technological spin-offs applicable to civilian use. Perhaps the most impressive and diversified of these byproducts of space research are those related to biomedicine. Space-related hardware, ranging from astronaut life support systems to missile nose cones, has been applied to literally hundreds

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library
FEBS Letters, EarlyView.LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.
