Solar dimming and brightening over Thessaloniki, Greece, and Beijing, China

, 2009
This work presents evidence that ultraviolet (UV)-A solar irradiances show increasing trends at Thessaloniki, Greece, where air quality has been improving because of air pollution abatement strategies.

Two Distinctly Different Characteristics of Flare-driven Coronal Rain Revealed from High-resolution Spectroscopic Imaging Observations with FISS/GST

The Astrophysical Journal
We report on a flare-driven coronal rain event observed along postflare loops during the decay phase of an X1.6-class solar flare. Although high-resolution studies of flare-driven coronal rain have been conducted, imaging spectroscopic studies are rare ...

Consumer Perceptions of Glycation‐Induced Facial Skin Aging and the Role of Skincare Products

Journal of Cosmetic Dermatology, Volume 25, Issue 10, October 2026.
ABSTRACT Background Glycation is a biological process known to exacerbate undesirable skin aging parameters such as yellowing, dullness, wrinkles and reduced elasticity. This study aimed to better understand consumer perceptions of glycation on facial skin and consumer expectations of anti‐glycation skincare. Methods Focus group discussions (FGDs) with

The Skin‐Lightening Efficacy and Mechanisms of Botanical Extracts: A Comprehensive Review

Journal of Cosmetic Dermatology, Volume 25, Issue 10, October 2026.
ABSTRACT Background Skin pigmentation is regulated by a complex network involving melanogenesis, melanosome transfer, oxidative stress, environmental stimuli, and epidermal turnover. Botanical extracts and phytochemicals have attracted increasing interest as potential skin‐lightening agents. This review evaluates their efficacy, mechanisms, and safety.

Magnetic Reconnection Driven by the Impact of a Magnetosheath High‐Speed Jet

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract High‐speed jets (HSJs) are transient structures in the magnetosheath characterized by enhanced dynamic pressure. While recent studies report that HSJs trigger magnetic reconnection at the magnetopause, whether they can directly drive reconnection within the magnetosheath remains an open question.

Satellite‐Based Global Assessment of Solar Resource Stability

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Satellite spatial smoothing complicates comparisons of solar variability between gridded products and point measurements. We introduce the Stability Deviation Index (SDI), a bounded composite of solar intensity and intraday variability. Applied independently to 69 BSRN stations and co‐located CERES grid cells, SDI shows strong cross‐platform ...

Wind‐Driven Circulation Feedbacks Offset Tropical Geoengineered Sea Salt Emissions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Using a NOAA Geophysical Fluid Dynamics Laboratory coupled atmosphere–ocean (CM4) comprehensive model, we employ simulations of enhanced, geoengineered sea salt aerosol (SSA) emissions in the tropics to examine the circulation response to idealized marine cloud brightening. Increased tropical SSA emissions cool the deployment region and weaken
