From the Proteome to Therapeutics: A Multi‐Database Approach to Drug Discovery in Periodontitis—An Exploratory Pilot Study

open access: yesJournal of Clinical Periodontology, Volume 53, Issue 7, Page 990-1004, July 2026.
ABSTRACT Introduction This explanatory pilot study presents a workflow to identify approved drugs, which could be repurposed for periodontitis therapy using salivary proteomics combined with drug‐target database screening. Methods Proteomic analyses of saliva using LC–MS/MS were conducted in two independent settings: a cohort (sub‐study I, N = 187) and

Spatiotemporal Evolution of Hydroclimatic Variables in the Brazilian Semi‐Arid Region Through the Aridity Index and Susceptibility to Desertification

open access: yesInternational Journal of Climatology, Volume 46, Issue 8, 30 June 2026.
Over the past 60 years, noticeable changes have been observed in the main hydroclimatological variables, driven by both natural and anthropogenic factors. In the context of climate change, such behaviour may adversely affect the state's economic activities, as well as increase the recurrence of extreme events in the region.

A Comparison of Rome Observatory Sunspot Area and Sunspot Number Determinations With International Measures, 1958-1998

open access: yes, 2005
Two changes in recording the sunspot record have occurred in recent years. First, in 1976, the longer-than-100-yr daily photographic record of the Royal Greenwich Observatory (RGO), used for determination of numbers and positions of sunspot groups and ...

Observing the Earth's Plasmasphere and Ionosphere From the Lunar Surface

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract We present the analysis of the first lunar‐based observational characterization of the Earth's plasmasphere and ionosphere using Global Navigation Satellite Systems signals tracked from the lunar surface by the Lunar GNSS Receiver Experiment (LuGRE). The Earth‐Moon geometry enables limb sounding of the plasmasphere at altitudes exceeding 3,000

Macroeconomic volatility and welfare loss under free-trade in two-country models [PDF]

open access: yes
This paper investigates the interlinkage in the business cycles based on sunspot fluctuations of large-country economies in a free-trade equilibrium. We consider a two-country, two-good, two-factor general equilibrium model with Cobb-Douglastechnologies,

Mercury's Eccentric Orbit as a Driver of Significant “Seasonal” Change in Upstream Solar Wind Forcing

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Mercury experiences the most intense and variable solar wind (SW) conditions in the solar system due to its close, eccentric orbit about the Sun. In addition to variation driven by coronal source and solar cycle, the SW arriving at Mercury varies periodically as the planet's heliocentric distance changes by over 50% per orbit.
