Each winter, thousands of blacktip sharks crowd South Florida’s clear, shallow shoreline—just as beach nourishment projects churn the water into murky plumes. In one of the most detailed studies to date, FAU researchers used aerial surveys and underwater cameras to track sediment clouds and shark activity. They found sharks cluster close to shore, where turbidity can stretch for miles, clouding visibility, disrupting feeding, and potentially shifting behavior—raising new concerns for marine ecosystems and human safety.

A recent study investigates the intermuscular bones (IBs) of a novel hybrid fish (BTB), derived from female Megalobrama amblycephala (BSB) and male Culter alburnus (TC), and its parents. The research reveals that BTB exhibits a reduced number of IBs per sarcomere compared to its parents, showcasing the potential of distant hybridization in developing fish varieties with fewer IBs, which is advantageous for both consumer preference and industrial processing.

Prenatal oxycodone exposure changes how the placenta sends signals to the fetus. A new study revealed how alterations in the protein composition of placental small extracellular vesicles (sEVs) impact fetal heart development. These changes suggest that maternal opioid use may raise the baby’s risk for future heart problems.

A study led by Qun-Ying Lei shows that PGG inhibits the MAT2A enzyme activity while simultaneously promoting its degradation. This unique dual-action induces pyroptosis and enhances antitumor immunity, presenting a promising new strategy for cancer immunotherapy.

Stockholm University and SciLifeLab research uncovers how glucose transporters achieve specificity, bridging a long-standing gap between structure and function in membrane biology. The study is published in Nature Structural & Molecular Biology.

Latent HIV-1 reservoirs are a major barrier to curing HIV because the virus can hide silently inside cells for years. In a laboratory model of HIV latency and in patient-derived cells, researchers found that exosomes released from Astragalus polysaccharide (APS)-treated reservoir cells can trigger HIV-1 reactivation. Multi-omics analyses and pathway validation point to a PI3K/AKT/NF-κB signaling mechanism, suggesting APS-associated exosome signaling as a bio-derived lead for “shock-and-kill” research.

A UAB research team defines the criteria these immunotherapies must meet to advance both conceptually and in trials, which are still at a very preliminary stage

They should have high selective precision and be programmable, sustained over time, and controllable throughout the pathologies. Macrophages, microglia and regulatory T cells would be appropriate effector cells for these treatments

A groundbreaking discovery in modernizing traditional Chinese medicine (TCM) has been achieved. A study has, for the first time, confirmed that stable, naturally occurring nanoparticles with intact bioactivity—named Pueraria lobata (GeGen) decoction-derived vesicle-like nanoparticles (GGD-PDVLNs)—exist in the decoction prepared using the traditional boiling method. Experiments have demonstrated that these nanoparticles constitute the core active component responsible for the therapeutic effects of the decoction. They function by reshaping the gut microbiota to treat ulcerative colitis, with efficacy dependent on the microbiota. This finding redefines the scientific understanding of traditional herbal decoctions and establishes a new paradigm for developing natural nanomedicines.
