The cometary and asteroidal impactor flux at the earth [PDF]

The cratering records on the Earth and the lunar maria provide upper limits on the total impactor flux at the Earth's orbit over the past 600 Myr and the past 3.3 Gyr, respectively.

Contemporary disasters may not kill more women than men: an empirical inquiry into sex‐differentiated fatalities in the twenty‐first century

Disasters, Volume 50, Issue 3, July 2026.
Abstract This study investigates the claim that women are disproportionately more likely to die in disasters by reviewing existing data sources and compiling new datasets on sex‐differentiated disaster fatalities in the twenty‐first century. The analysis is structured by disaster type, covering geophysical, meteorological, climatological, hydrological,

Redox Regulation and Oxidative Stress in Health and Disease: Mechanisms and Therapeutic Targeting

MedComm – Future Medicine, Volume 5, Issue 2, June 2026.
Reactive species serve crucial roles which are tightly regulated in both physiological as well as disease states. At physiological levels, these species are integral to redox signaling, while uncontrolled redox promotes disease pathology. This review examines the dysregulation of these processes.

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 ...

Synergistic RU486 and olaparib therapy enhances apoptosis in endometriosis by simultaneously targeting hormonal signalling and DNA repair

British Journal of Pharmacology, Volume 183, Issue 11, Page 2947-2968, June 2026.
Background and Purpose Endometriosis is a chronic, hormone‐dependent disorder characterized by ectopic implantation of endometrial tissue, often accompanied by pain and infertility. Although the progesterone receptor modulator RU486 is effective for pain relief, its impact on lesion regression is limited, possibly due to apoptosis resistance and ...

Combustion and Pyrolysis EA‐IRMS Techniques to Determine the δ2H of Diamonds

Rapid Communications in Mass Spectrometry, Volume 40, Issue 10, 30 May 2026.
ABSTRACT Rationale Diamonds are generally considered to be metasomatic minerals originating from the Earth's mantle. They formed through the interaction of carbon‐bearing fluids or melts with the surrounding deep lithology. Most knowledge about the formation of diamonds comes from studying their mineral inclusions or stable isotopes.

Elevated TRIM25 Impairs Poly (ADP‐ribose) Metabolism via PARG Degradation and Mediates Compression‐Induced Intervertebral Disc Degeneration

Advanced Science, Volume 13, Issue 25, 4 May 2026.
TRIM25 acts as a multifunctional hub driving intervertebral disc degeneration under mechanical stress. Mechanical compression significantly upregulates TRIM25 expression, establishing it as a key E3 ubiquitin ligase platform. TRIM25 targets PARG and Ku80 via distinct molecular interfaces, triggering their ubiquitination and degradation.
