Bacterial symbionts support larval sap feeding and adult folivory in (semi-)aquatic reed beetles

Nature Communications, 2020
Symbiotic microbes in insects can enable their hosts to access untapped nutritional resources. Here, the authors show that symbiotic bacteria in reed beetles can provide essential amino acids to sap-feeding larvae and help leaf-feeding adults to degrade ...

Circulating histones as clinical biomarkers in critically ill conditions

FEBS Letters, EarlyView.
Circulating histones are emerging as promising biomarkers in critical illness due to their diagnostic, prognostic, and therapeutic potential. Detection methods such as ELISA and mass spectrometry provide reliable approaches for quantifying histone levels in plasma samples.

Neuropeptidergic Systems in Pluteus Larvae of the Sea Urchin Strongylocentrotus purpuratus: Neurochemical Complexity in a “Simple” Nervous System

Frontiers in Endocrinology, 2018
The nervous system of the free-living planktonic larvae of sea urchins is relatively “simple,” but sufficiently complex to enable sensing of the environment and control of swimming and feeding behaviors.

Insights into pegRNA design from editing of the cardiomyopathy‐associated phospholamban R14del mutation

FEBS Letters, EarlyView.
This study reveals how prime editing guide RNA (pegRNA) secondary structure and reverse transcriptase template length affect prime editing efficiency in correcting the phospholamban R14del cardiomyopathy‐associated mutation. Insights support the design of structurally optimized enhanced pegRNAs for precise gene therapy.

Stellar Yields and Chemical Evolution [PDF]

Symposium - International Astronomical Union, 2002
Several speakers at this symposium have alluded to the zeroth-order agreement between the Type II supernovae (SNe) stellar yields, as predicted by the models of those most responsible for driving progress in the field - i.e. Arnett (1991,1996); Maeder (1992); Woosley & Weaver (1995); Langer & Henkel (1995); Thielemann et al.

Single‐cell insights into the role of T cells in B‐cell malignancies

FEBS Letters, EarlyView.
Single‐cell technologies have transformed our understanding of T cell–tumor cell interactions in B‐cell malignancies, revealing new T‐cell subsets, functional states, and immune evasion mechanisms. This Review synthesizes these findings, highlighting the roles of T cells in pathogenesis, progression, and therapy response, and underscoring their ...

Thermodynamic evolution theorem for chemical reactions

Physical Review Research, 2020
The production, exchange, and balance of entropy characterize the thermodynamics of open nonequilibrium systems, ranging from chemical reactions, cells, ecological systems, and Earth-like planets to stars.

Revisiting the Fundamental Metallicity Relation with Observation and Simulation

The Astrophysical Journal Letters
The gas-phase metallicity of galaxies is regulated by multiple astrophysical processes, which makes it a crucial diagnostic of galaxy formation and evolution.

Searching for lost nucleotides of the pre-RNA World with a self-refining model of early Earth

Nature Communications, 2018
The nucleotides of RNA appear to be products of evolution. Experimental studies are showing that plausible proto-nucleotides can be formed in simulated early Earth environments.
