An Engineered HR1‐Stem Helix‐HR2 Trimeric Platform for Developing Broad‐Spectrum Coronavirus Vaccines

open access: yesAdvanced Science, EarlyView.
Sun et al. report a self‐assembling trimeric subunit vaccine platform termed RHS, which integrates the JN.1 receptor‐binding domain (RBD) with the heptad repeat 1 (HR1), stem helix (SH), and heptad repeat 2 (HR2) regions. The SARS‐CoV‐2 RHS vaccine elicits variant‐reactive RBD‐specific antibodies and cross‐reactive SH‐specific antibodies against ...

Implications of differences between temperate and tropical freshwater ecosystems for the ecological risk assessment of pesticides [PDF]

open access: yes, 2010
Despite considerable increased pesticide use over the past decades, little research has been done into their fate and effects in surface waters in tropical regions.

Dual pKa Lipid Nanoparticles for Lung‐tropic mRNA Delivery and pH‐Programmed Endosomal Escape

open access: yesAdvanced Science, EarlyView.
Lipid nanoparticles’ bottleneck lies in low endosomal escape efficiency and liver‐dominant delivery after intravenous administration. To overcome these limitations, we present a stepwise pH‐programmed lipid nanoparticle system enabled by our newly synthesized ionizable lipid.

Local environmental conditions related to seasonal tropical cyclone activity in the Northeast Pacific basin [PDF]

open access: yes, 2000
Tropical cyclone formation in the NE Pacific Ocean is poorly understood. We show that by dividing the NE Pacific Ocean into two regions, east and west of 116 degreesW, our understanding is enhanced in terms of which climatological factors are involved ...

Bridging Horizontal to Vertical Radiative Cooling

open access: yesAdvanced Science, EarlyView.
Radiative cooling materials are mature but only work facing the sky, confining them to rooftops. Instead of developing new ones, this system bridges existing horizontal coolers to vertical windows using blades outside the glass. On an occupied urban building, windows stay up to 1.4°C below air temperature while preserving daylight, outward views, and ...

Symbiont‐Induced HSP83 Establishes Two‐Tiered Control of Antifungal Immunity in an Invasive Beetle–Fungus Complex

open access: yesAdvanced Science, EarlyView.
In an invasive beetle–fungus complex, the mutualist Leptographium procerum induces host HSP83 and modulates Toll‐dependent antifungal immunity. HSP83 mediates two‐tiered control by associating with selected fungal recognition receptors and restraining Dorsal‐driven antimicrobial peptide transcription.

Exploring Post-Harvest Processing of Tropical Crops: Moringa oleifera and Zea mays as Alternative Ingredients for Gluten-Free Pasta Production [PDF]

open access: yes
This study examines the potential of Moringa oleifera (moringa) and Zea mays (corn), two tropical crops, as alternative ingredients for gluten-free pasta, with a focus on their post-harvest processing to enhance their utility in gluten-free pasta ...

Synergistic Effects in Multistate Black Electro‐Thermochromic Smart Windows for Energy‐Efficient Modulation of Solar Heating

open access: yesAdvanced Science, EarlyView.
Hybrid electro‐thermochromic smart windows are developed for dynamic climate control by integrating a redox‐matched black electrochromic gel with a paraffin‐based thermochromic film. This synergistic combination enables multimodal solar modulation, where photothermal heating from the electrochromic layer triggers thermochromic activation at lower ...

Determination of the silvo-melliferous regions of Benin: a nationwide categorisation of the land based on melliferous plants suitable for timber production

open access: yesJournal of Agriculture and Rural Development in the Tropics and Subtropics, 2015
Perennial plants are the main pollen and nectar sources for bees in the tropical areas where most of the annual flora are burned in dry seasons. Therefore perennial plants constitute the most reliable bio materials for determining and evaluating the ...
