Effect on head-wind profiles and mean head-wind velocity on landing capacity flying constant-airspeed and constant-groundspeed approaches [PDF]
A study was conducted to determine the effect of head-wind profiles and mean head-wind velocities on runway landing capacity for airplanes flying constant-airspeed and constant-groundspeed approaches.

Advanced Science, EarlyView.This study reveals that Urolithin A (UA) counteracts alcohol‐induced cognitive and social dysfunction (AICSD) via a gut microbiome‐dependent mechanism. UA‐enriched Bacteroids sartorii and Parabacteroids distasonis elevate anandamide (AEA), which activates the CB1R‐DRD2‐Rap1 signaling cascade to drive synaptic repair and reduce neuroinflammation ...

Ribosome Homeostasis Regulated by SETD2 Preserves Intestinal Epithelial Barrier
Advanced Science, EarlyView.SETD2 ablation causes dysregulation and recruitment defects of ribosome biogenesis factors, resulting in translational disorders of barrier maintenance genes, thereby compromising the intestinal barrier. These findings unveil a previously unappreciated role of ribosome biogenesis and translational regulation in preserving the intestinal epithelial ...

A Degradable Bioinspired Flier with Aerogel‐Based Colorimetric Sensors for Environmental Monitoring
Advanced Science, EarlyView.Biodegradable fliers are developed inspired by Tipuana tipu samaras, integrating cellulose nanocrystal aerogel (CNCa) sensors loaded with natural dyes for pH and ammonia detection. The lightweight, degradable fliers mimic natural morphology and aerodynamics, offering an eco‐friendly, scalable solution for in situ environmental monitoring after passive ...

Ecosystem‐Centered Robot Design: Toward Ecoresorbable Sustainability Robots (ESRs)
Advanced Science, EarlyView.Robots exploring natural ecosystems can support monitoring and conservation, but must adopt ecosystem‐centered design to avoid pollution, waste, and damage. This review proposes guidelines for co‐designing ecoresorbable sustainability robots (ESRs), uniting materials, robotics, and ecological contexts in a single framework.

The Effect of Propellers and Nacelles on the Landing Speeds of Tractor Monoplanes [PDF]
This paper reports wind-tunnel tests giving the lift coefficients of large-scale wing-nacelle combinations both with and without the propeller. The tests were made to show the effect of nacelles, and idling and stopped propellers on the landing speeds of

Advanced Science, EarlyView.We investigate by proteomics studies how strand‐symmetric and ‐asymmetric cytosine 5‐modifications in DNA are selectively recognized by the nuclear proteome. Using promoter probes with defined modification patterns, we identify tissue‐specific reader proteinsincluding MYC, MAX, and RFX5that discriminate 5‐hydroxymethylcytosine symmetry and sequence ...
