The HIPRA-HH-2 was a multicentre, randomized, active-controlled, double-blind, non-inferiority phase IIb clinical trial comparing the immunogenicity and safety of the PHH-1V adjuvanted recombinant vaccine as a heterologous booster against homologous booster with BNT162b2. Interim results demonstrated strong humoral and cellular immune response against the SARS-CoV-2 Wuhan-Hu-1 strain and the Beta, Delta, and Omicron BA.1 variants up to day 98 post-dosing.

The adsorbents, SW + AL, SW + AL + BC, SW + AL + CMC, NSW + AL, NSW + AL + BC, NSW + AL + CMC, AL, and AL + CMC were prepared for the adsorption of the antibiotic sulfadiazine (SDZ). The test samples were characterized using a variety of techniques, including X-Ray Diffraction (XRD), IR spectroscopy (FT-IR), and scanning electron microscopy (SEM), with the molecular structures of the studied additives geometrically optimized using the DFT/B3LYP method and the function 6-311G(d).

- Extreme climatic events (ECEs) like marine heatwaves pose serious threats to biodiversity, highlighting the need for understanding ecological responses to these recurring events.
- Researchers used a "multiple events" approach to study the effects of recurrent ECEs on the temperate coral Paramuricea clavata, assessing factors like environmental, genetic, and phenotypic influences over three years.
- Findings indicated that environmental impacts were the primary drivers of coral responses, with limited evidence of genetic adaptability, suggesting that P. clavata populations face significant challenges due to ongoing heat stress and may struggle to recover.
The presence of pharmaceuticals in agricultural soils, like amoxicillin (AMX) and ciprofloxacin (CIP), poses a significant environmental challenge with potential implications for ecosystems and human well-being. This study explores the simultaneous adsorption of AMX and CIP on crop soils and bio-adsorbents, focusing on competitive adsorption dynamics. Tests were conducted with varying pharmaceutical concentrations in six soils and three bio-adsorbents.

- - The study focuses on the Magellan Subantarctic ecoregion, highlighting how accelerated glacial ice melt creates unique environmental conditions that impact marine biodiversity and epiphytic microalgal communities.
- - Researchers analyzed epiphytic microalgal assemblages on various benthic macroalgae across sites with different glacial and oceanic influences, documenting 67 genera and noting significant variations in diversity based on environmental factors.
- - Findings revealed that environmental gradients, particularly from glacial influence, are the primary drivers of epiphytic variation, with some potentially harmful microalgae identified, contributing to a better understanding of this complex ecosystem in light of climate change.
