Osmomixotrophy in Phytoplankton: Analysis of 46 Strains From Marine and Freshwater Habitats Indicates Prevalent Use of Organic Compounds

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Analysing thousands of data points across 46 marine and freshwater strains, this study underscores that osmomixotrophy is a common, rather than exceptional, metabolic strategy in phytoplankton. These findings challenge the autotrophic paradigm, demonstrating that organic matter acquisition is a default state with significant implications for our ...

Performance of Automated Hematology Analyzer Criteria in Detecting Peripheral Blood Smear Abnormalities: A Systematic Literature Review

open access: yesInternational Journal of Laboratory Hematology, Volume 48, Issue 5, Page 1008-1022, October 2026.
ABSTRACT Objectives Criteria for visual examination of stained peripheral blood smear (PBS) differ among institutions in the United States and internationally. In an effort to standardize review criteria, the International Consensus Group for Hematology Review (ICGHR) proposed in 2005 a consensus list of rules for CBC findings that should trigger a ...

Functional interactions between anteroventral periventricular kisspeptin neurons and gonadotropin‐releasing hormone neurons in female mice

open access: yesJournal of Neuroendocrinology, Volume 38, Issue 10, October 2026.
Abstract Kisspeptin neurons in the rostral hypothalamus are hypothesized to initiate preovulatory gonadotropin‐releasing hormone (GnRH) surges by causing estradiol‐dependent activation of GnRH neuron action potential firing and subsequent GnRH release.

Simulating Regional‐Scale Aerosol Radiative Effects of Wildfire Smoke Using a High‐Resolution Coupled Meteorology‐Chemistry Model: HRRR‐Chem

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract Wildfires are increasing in frequency and intensity, strongly influencing both regional air quality and the Earth's radiation budget via their aerosol emissions. Relying on an unparalleled observational data set from the 2019 NOAA/NASA FIREX‐AQ campaign, this study quantifies the direct radiative effects of two wildfires using the HRRR‐Chem ...
