The impacts of coronal mass ejections on the space environments of Venus and Mars

地球与行星物理论评
Coronal mass ejections (CME) are solar transients, and their impacts on the planets within the solar system have attracted considerable attention. As neighboring planets within the solar system, Venus and Mars are also directly and indirectly affected by

Note on Inquiries as to the Escape of Gases from Atmospheres [PDF]

The Astrophysical Journal, 1900
Abstract We have now three investigations which profess to supply information about the escape of gases from atmospheres. Two of them, those of Messrs. Cook and Bryan, reason forward by the help of the kinetic theory of gas from the supposed causes; the third, which is that preferred by the present writer, reasons backward by the help

Mitigating Cancer Therapy–Related Cognitive Impairment by Targeted Activation of Undruggable Phosphatase

Advanced Science, EarlyView.
An RVG‑engineered exosomal saRNA delivery system (RVG‑EVs‑saPtpro) effectively targets and activates hippocampal PTPRO, functioning as a “molecular brake” to alleviate cancer therapy‑related cognitive impairment (CTRCI) by enhancing neuronal survival, neurogenesis, and synaptic plasticity.

Helium Depletion in Escaping Atmospheres of Sub-Neptunes: A Signature of Primary-to-secondary Transition

The Astrophysical Journal
Short-period sub-Neptunes are common in extrasolar systems. These sub-Neptunes are generally thought to have primary atmospheres of protoplanetary-disk gas origin.

The response of exospheric neutral hydrogen to weak geomagnetic disturbances between June 12 and 29, 2008

Frontiers in Astronomy and Space Sciences
Stereoscopic remote sensing observations of terrestrial far ultraviolet (Lyman-α at 121.6 nm) emissions at solar minimum have been used to retrieve the time-dependent response of the exospheric 3-D neutral hydrogen (H) density at radial distances of 3–6 ...

Escape of atmospheric gases from the Moon

Journal of Earth System Science, 2005
The escape rate of atmospheric molecules on the Moon is calculated. Based on the assumption that the rates of emission and escape of gases attain equilibrium, the ratio of molecular number densities during day and night, n0d/n0n, can be explained.

Single‐Cell Dissection of Therapy‐Induced Remodeling Uncovers a Fibroblast‐Driven Immunosuppressive Niche and Targetable Vulnerabilities in Lethal Prostate Cancer

Advanced Science, EarlyView.
Single‐cell longitudinal profiling reveals that androgen‐deprivation therapy induces a DPT+ fibroblast‐complement axis that suppresses macrophage inflammation and drives CD8+ T cell exhaustion in prostate cancer. Concurrently, resistant epithelial subpopulations persist and engage TSPAN1‐ and NRXN1‐mediated programs promoting CRPC and neuroendocrine ...

On the Divergent Evolution of Io and Europa as Primordial Ocean Worlds

The Astrophysical Journal
The Galilean moons exhibit a decrease in bulk density with distance from Jupiter, which may reflect differences in evolutionary paths and water loss. Early in its history, Jupiter was more luminous, which may have driven substantial atmospheric escape on

TME/NIR Dual‐Responsive Zinc‐Based Targeted Nanoagonist for Multimodal Amplification of STING‐Mediated Cancer Immunotherapy

Advanced Science, EarlyView.
A multifunctional nanoagonist (cDZ@IP) enables nano‐metabolite–driven multimodal activation of the STING pathway and enhanced immune recognition, achieving potent antitumor immunity and suppressing tumor growth and metastasis. This strategy highlights the rational design of therapeutic metabolites and establishes a new paradigm bridging nanomedicine ...

Predictive analytics of cold ion outflow from the Earth’s ionosphere

Frontiers in Astronomy and Space Sciences
In this study, we investigate the cold ions (<70 eV) originated in the high-latitude ionosphere of the Earth entering the magnetosphere towards the magnetotail.
