Unusual Enhancement in He(23S) Airglow Brightness Associated With Interplanetary Magnetic Field Northward Turnings During the 2025 New Year's Day Storm

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract The upper thermosphere is important in the context of space weather, but continuous monitoring of the thermosphere at high latitudes remains limited despite its strong variations associated with geomagnetic activity. Orthohelium, He(23S), is found from the upper thermosphere to lower exosphere, and is a promising tracer of atmospheric dynamics.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, Volume 600, Issue 19, Page 2947-2960, October 2026.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Associations of plasma HDL subclasses with incident dementia risk in older adults

open access: yesAlzheimer's &Dementia, Volume 22, Issue 10, October 2026.
Abstract INTRODUCTION Plasma high‐density lipoprotein (HDL) varies in size. We examined the associations between HDL subclasses and their lipid composition and incident dementia risk in older adults. METHODS We included 23,790 United Kingdom (UK) Biobank (UKB) and 147 Atherosclerosis Risk in Communities (ARIC) older adults free of dementia at baseline.

Implementation of an SDR in Verilog

open access: yes, 2016
This report presents an implementation of the software part in a software definedradio. The radio is not entirely implemented in software and therefore there arecertain limitations on the received signal. The parts implemented are oscillator,decimation filter, carrier synchronization, time synchronization, package detection,and demodulation.

Peptide Marriages: Modular Assembly of Multi‐Agonist Therapeutics

open access: yesChemistry – A European Journal, Volume 32, Issue 37, 1 October 2026.
A modular polyethylene glycol (PEG) scaffold enables rapid assembly of dual peptide agonists using strain‐promoted azide–alkyne cycloaddition (SPAAC) and copper‐catalysed azide–alkyne cycloaddition (CuAAC). Glucagon‐like peptide‐1 (GLP‐1) and amylin agonists were combined with controlled valency, yielding low‐picomolar activity and receptor‐selective ...
