Chromatin Topology Reconfiguration Orchestrates Thermotolerant Male Fertility via GhAL5 in Cotton

Advanced Science, Volume 13, Issue 14, 9 March 2026.
This study investigates cotton’s high‐temperature (HT) response using multi‑omics. Dynamic 3D genome changes drive expression bias affecting male fertility. The tolerant line shows controlled chromatin dynamics, while the sensitive line exhibits overactivation.

Evaluating the Contributions of Tianwen-1 Orbiter Tracking Data to the Mars Gravity Field Modeling

The Astrophysical Journal
Mars gravity field models are critical data sets for studying the planet’s internal structure. Currently, Mars gravity field determination is primarily based on modeling of tracking data from spacecraft such as Mars Reconnaissance Orbiter, Mars Odyssey ...

Electrode Engineering for High‐Durability Variable‐Emissivity Devices Based on Reversible Copper Electrodeposition

Advanced Science, Volume 13, Issue 11, 23 February 2026.
An Ir‐based reversible copper electrodeposition variable‐emissivity device achieved over 8000 cycles with just 11% radiative temperature variation decay. This stability stems from Ir's inherent inertness, high conductivity, and strength, which collectively suppress cracking and corrosion.

A High-Accuracy, High Anti-Noise, Unbiased Frequency Estimator Based on Three CZT Coefficients for Deep Space Exploration Mission

Sensors, 2022
Deep space exploration navigation requires high accuracy of the Doppler measurement, which is equivalent to a frequency estimation problem. Because of the fence effect and spectrum leakage, the frequency estimation performances, which is based on the FFT

Nanosatellite Launch Forecasts - Track Record and Latest Prediction [PDF]

, 2022
After almost 300 CubeSats were sent to space in 2017, the following 3 years saw a continued decline. While 2021 set a new record of about 326 nanosatellites launched, most published forecasts and expectations from the last 10 years about the growth about

An overview of sedimentary volcanism on Mars [PDF]

, 2023
Extensive fields of sub-kilometre-to kilometre-scale mounds, cones, domes, shields, and flow-like edifices cover large parts of the martian lowlands. These features have been compared to structures on Earth produced by sedimentary volcanism – a ...

Investigation on the Coherent Component of SHARAD Surface Echo and Surface Roughness: Scaling Behavior and Influence of Hurst Exponent

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract The radar surface echo can be separated into coherent and incoherent components by statistical approaches, and the coherent component can be described by a backscattering model related to the RMS height. According to backscattering models for fractal surfaces, the coherent power in decibels decreases with RMS height on a scale independent of ...
