Cerebral Hemodynamic Changes During Cardiac Surgery: A Feasibility MR Study in Piglets

open access: yesNMR in Biomedicine, Volume 39, Issue 5, May 2026.
Congenital heart disease surgery in infants requires cardiopulmonary bypass (CPB), which increases the risk of brain injury. Conventional heart‐lung machines (HLMs) cannot operate inside MRI scanners, limiting real‐time assessment of cerebral changes. We developed an MR‐conditional HLM and tested it in piglets during CPB.

A Hybrid Biophysical‐Machine Learning Framework for Diurnal Surface Energy Flux Estimation Using Proximal Sensing

open access: yesWater Resources Research, Volume 62, Issue 5, May 2026.
Abstract Thermal infrared‐based remote sensing of surface energy fluxes has traditionally relied on high spatial resolution satellite data with revisit frequencies on the order of weeks. In this study, we evaluate a biophysics‐based analytical surface energy balance model for predicting latent energy (LE) and sensible heat (H) fluxes using proximal ...

A multi‐trait evaluation of patterns and fitness consequences of breeding phenology plasticity with nocturnal warming and food restriction in a lizard

open access: yesFunctional Ecology, Volume 40, Issue 5, Page 1233-1250, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Faced with climate warming, ectothermic species shift their breeding phenology, which is in part attributed to an acceleration of gestation or incubation in warmer environments.

Detection of Heat and Drought Effects on the Photosynthetic Activity Using Solar‐Induced Chlorophyll Fluorescence and a Photochemical Reflectance Index in a Cool‐Temperate Larch Forest in Japan

open access: yesEcological Research, Volume 41, Issue 3, May 2026.
Solar‐induced chlorophyll fluorescence (SIF) and gross primary productivity decline at midday during a short heatwave in a tower site of a larch forest. High atmospheric vapor pressure deficit significantly reduced the photochemical reflectance index (PRI), light‐use efficiency (LUE), and canopy fluorescence emission efficiency (εF).

Enhancing the vase life of cut roses through spectral optimisation during greenhouse cultivation

open access: yesAnnals of Applied Biology, Volume 188, Issue 3, Page 656-673, May 2026.
Here, we examined three red‐to‐blue (R:B) light emitting diode (LED) ratios (90:10, 80:20 and 70:30) in two cut rose cultivars. All treatments enhanced photosynthesis, with 90:10 showing the strongest effects—raising chlorophyll, carotenoids, anthocyanins and carbohydrate levels, and extending vase life by up to 30%.

Impact of cooling garments on performance during and after vigorous, heart‐rate‐clamped exercise in young males under hot and humid conditions

open access: yesPhysiological Reports, Volume 14, Issue 9, May 2026.
Abstract This study aimed to clarify the effects of the following cooling garments on performance during and after vigorous, heart‐rate‐clamped exercise under hot and humid conditions: base layers made of cross‐shaped fibers (C), sugar alcohol‐printed base layers (S), and a combination of S with a fan‐attached jacket (S+F).
