Interstellar Object 3I/ATLAS Observed from Mars by China’s Tianwen-1 Spacecraft

The Astrophysical Journal Letters
China’s Tianwen-1 Mars orbiter successfully imaged the third interstellar object, 3I/ATLAS, during its close encounter with Mars using the onboard HiRIC CMOS camera. This is China’s first deep-space observation of an astronomical object.

The effect of the impact of comet Shoemaker Levy‐9 on Jupiter's aurorae [PDF]

, 1995
We present infrared spectra and images of the jovian aurorae taken at wavelengths sensitive to the H-3(+) molecular ion during the period around the impact of Comet Shoemaker Levy-9.

Macrophage RSAD2 Couples mtDNA Synthesis With a Self‐Amplifying Inflammatory Circuit to Orchestrate Tissue Repair

Advanced Science, EarlyView.
Macrophage RSAD2 dually regulates CMPK2—the rate‐limiting enzyme for mitochondrial DNA synthesis—by suppressing its ubiquitination and promoting its phosphorylation via Csnk2a2 recruitment. This amplifies mtDNA production, which simultaneously activates a cGAS‐STING‐IRF3‐RSAD2 feedforward loop and the NLRP3 inflammasome, driving a self‐sustaining ...

Comet Gas and Dust Dynamics Modeling [PDF]

, 2010
This software models the gas and dust dynamics of comet coma (the head region of a comet) in order to support the Microwave Instrument for Rosetta Orbiter (MIRO) project. MIRO will study the evolution of the comet 67P/Churyumov-Gerasimenko's coma system.

Targeting LDHA Palmitoylation Sensitizes GBM to Chemoradiotherapy via Suppressing Palmitic Acid Induced Glycolytic Reprogramming

Advanced Science, EarlyView.
Mesenchymal GSCs preferentially uptake palmitic acid, thereby promoting ZDHHC12‐mediated LDHA palmitoylation. This modification enhances LDHA enzymatic activity, drives glycolytic reprogramming, and facilitates exosomal LDHA‐mediated TAM regulation.

Monitoring Cometary Activity of 60P/Tsuchinshan During Its 2018–2019 Apparition

The Astrophysical Journal, 2023
Comet 60P/Tsuchinshan is a Jupiter family comet. Since the discovery of 60P/Tsuchinshan, little research for cometary activity has been conducted on this comet, though it has returned to perihelion several times.

Stimulation of OGG1 Enhances Oxidative DNA Damage Repair and Protects Against Acute Liver Failure by Acetaminophen

Advanced Science, EarlyView.
Chemical switching of OGG1 by CMM‐98 accelerates oxidative DNA damage repair and enhances hepatocyte resilience during acetaminophen‐induced acute liver injury. By promoting efficient processing of OGG1‐generated repair intermediates, CMM‐98 reduces oxidative damage, preserves cellular integrity, and protects against acute liver failure, identifying ...

Analysis of CN Coma Morphology Features of Comet 21P/Giacobini–Zinner

The Planetary Science Journal, 2023
We analyze jet features found in the coma of comet 21P/Giacobini–Zinner (21P/GZ) during its 2018 perihelion passage using narrowband CN photometric imaging in order to determine the comet’s rotational period, and we constrain the CN gas outflow velocity ...

Excitation‐Selective Hydrochromic Upconversion in Zero‐Dimensional Metal Halides

Advanced Science, EarlyView.
Excitation wavelength dictates whether moisture speaks. In zero‐dimensional metal halides, the same humidity leaves the upconversion emission unchanged under 980 nm excitation yet triggers a distinct green‐to‐red shift under 1550 nm. This excitation‐selective hydrochromism, governed by the absorption at each wavelength, enables stimulus‐dependent ...
