Experimental reconstruction of monsoon drought variability for Australasia using tree rings and corals

Geophysical Research Letters, 2008
An experimental reconstruction uses three well‐dated, annually‐resolved proxies from Australasia (0–40°S, 95–155°E) to provide large‐scale information on Sep–Jan Australasian monsoon variability based on the Palmer Drought Severity Index (PDSI) for 1787 ...

Comparing tree-ring based reconstructions of snowpack variability at different scales for the Navajo Nation

Climate Services, 2021
Snowpack in the western U.S. is on the decline, largely attributed to increasing temperatures in the region. This is a critical issue for many Native American communities who disproportionately rely on local snow-fed water supplies.

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Drought intensity affects radial growth and recovery of P. schrenkiana at varying elevations in the Western Tianshan Mountains, China

Forest Ecosystems
As climate change intensifies, forests increasingly face the challenges posed by more frequent and severe droughts. However, the impacts of drought intensity on post-drought growth recovery and compensatory growth in trees remain poorly understood ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
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.

Tropical volcanoes synchronize eastern Canada with Northern Hemisphere millennial temperature variability

Nature Communications, 2022
A maximum latewood density based summer temperature reconstruction from eastern Canada shows recent warming is unprecedented over 1246 years, and tropical volcanism synchronizes regional and hemispheric summer temperatures at the multidecadal time scale.
