Intranasal Delivery of Bacterial Extracellular Vesicles Enables RNA Cargo Entry Into the Brain

Journal of Extracellular Vesicles, Volume 15, Issue 6, June 2026.
ABSTRACT Extracellular vesicles (EVs) released by bacteria are potent mediators of host–microbe interactions. They modulate immune responses, deliver functional molecules and influence disease progression. However, whether bacterial EVs can access the brain and functionally affect host cells remains unclear.

Relaxation Time Mapping of Early‐Stage Osteonecrosis of the Femoral Head: An In Vivo Piglet Model Study

Journal of Orthopaedic Research, Volume 44, Issue 6, June 2026.
T2, T1ρ, adiabatic T1ρ, and adiabatic T2ρ relaxation time mapping techniques are sensitive in detecting ischemic injury to bone marrow of the femoral head in vivo in a piglet model at 3 T MRI. T2 and adiabatic T2ρ relaxation times have the most pronounced increase in ischemic versus perfused, contralateral‐control femoral heads 1 week after induction ...

Platelet‐Rich Fibrin Induces New Bone Formation to Promote Extreme Lateral Interbody Fusion of Spine in Rabbits

JOR SPINE, Volume 9, Issue 2, June 2026.
Preparation process of PRF and its promotion of intervertebral fusion. The rabbit lateral fusion model proves that PRF can promote the intervertebral fusion rate of allograft bone. In vitro experiments can be observed that PRF promotes the osteogenic expression of BMSCS.

From cells to reefs—fluorescent protein distribution reveals species‐specific photoadaptation in closely related Caribbean corals

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Fluorescent proteins (FPs) are diverse and widespread pigments in reef‐building corals, assumed to modulate the internal light microenvironment within coral tissues. Yet, their precise distribution and organization at the tissue and cellular levels remain poorly understood, limiting our understanding of their functional roles.

Improved Constraints on Andean Glaciations From the Lake Titicaca Continental Drilling Record

Paleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.
Abstract Long sedimentary records from tropical lakes provide crucial archives for reconstructing the timing and extent of tropical alpine glaciations, yet robust chronologies beyond the radiocarbon limit (ca. 50 ka) remain scarce. Here, we refine the ca. 350 kyr chronology for Lake Titicaca (Peru‐Bolivia) using radiocarbon dating, optically stimulated
