Terrestrial Analogs to Titan for Geophysical Research

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

A novel mechanism for outbursts of Comet 17P/Holmes and other short-period comets

, 2007
A mechanism is proposed to explain the outburst of comet 17P/Holmes based on; (a) oxidation of water within the porous surface of the comet nucleus to form hydrogen peroxide (H2O2) through exposure to UV radiation, to energetic solar-wind particles and to cosmic radiation, (b) concentration of the H2O2 component through solid-, liquid- and gas-phase ...

Advancing Heliophysics and Space Weather Modeling Through Open Science

Space Weather, Volume 24, Issue 6, June 2026.
Abstract We present a community‐wide effort to develop a strategy and action plan to advance heliophysics and space weather modeling through open science. While open science has the potential to enhance the quality and pace of scientific discovery, its application to scientific modeling requires more careful consideration regarding open data and open ...

Source Parameters of the 1906 Manas (Mw 7.7), 1944 Xinyuan (Mw 7.2) and 1812 Nilke Earthquakes and Seismotectonics of the Borohoro Shan, Western China

Tectonics, Volume 45, Issue 6, June 2026.
Abstract The 1906 Manas Earthquake is the largest earthquake recorded in the Borohoro Shan (BRS) since 1900. The reported magnitude ranges from 7.2 to 8.3, but uncertainties remain regarding its size, mechanism, and responsible fault. Similar confusion exists for the 1812 Nilke and 1944 Xinyuan Earthquakes, the only other Mw > 7 earthquakes in the NE ...

Effects of Comet Encke's Meteoroid Stream on the Seasonal Variation of Mercury's Ca Exosphere

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Mercury's calcium (Ca) exosphere, observed by NASA's MESSENGER mission, exhibits high temperatures (>50000 K) and pronounced seasonal variability, with its source mainly on the dawn side. Enhanced Ca emission near True Anomaly Angle (TAA) ∼25° and ∼150° has been attributed to Comet 2P/Encke meteoroid streams.

What can lithics tell us about food production during the transition to farming? Exploring harvesting practices and cultural changes during the neolithic in Southwest Asia: a view from Qminas (north‐western Syria)

Archaeometry, Volume 68, Issue S3, Page S126-S153, June 2026.
Abstract This study examines the continuity and change in harvesting practices between the Late Pre‐Pottery Neolithic B (LPPNB) and the Early Pottery Neolithic at Qminas, north‐western Levant, through a traceological analysis of flint sickles. By combining qualitative traceological analysis with quantitative functional approaches, we demonstrate that ...

Dual PARP/Tankyrase Inhibition Enhances Antitumor Efficacy in PTEN‐Deficient Endometrial Cancer

Journal of Cellular and Molecular Medicine, Volume 30, Issue 11, June 2026.
ABSTRACT Endometrial cancer (EC) incidence continues to rise, underscoring the need for effective therapies beyond BRCA‐mutant disease. Although PTEN loss, a frequent alteration in EC, has been implicated in impaired homologous recombination and increased sensitivity to PARP inhibitors, responses to PARP inhibitor monotherapy remain variable and are ...
