With about 2000 exoplanets discovered within a large range of different configurations of distance from the star, size, mass, and atmospheric conditions, the concept of habitability cannot rely only on the stellar effective temperature anym...
First Evidence on the Role of Heavy Ion Irradiation of Meteorites and Formamide in the Origin of Biomolecules [0.03%]
重离子辐照对陨石和甲酰胺在生物分子起源中作用的首次证据

Formamide (NH2CHO) has been irradiated in condensed phase at 273 K by 11B-boron beams in the presence of powdered meteorites of the chondrite and stony-iron types. Relative to the controls (no radiation or no catalysis), a variegate panel o...
Proton Gradients as a Key Physical Factor in the Evolution of the Forced Transport Mechanism Across the Lipid Membrane [0.03%]
质子梯度作为脂质膜跨膜强制运输机制进化过程中的关键物理因素

A critical phase in the transition from prebiotic chemistry to biological evolution was apparently an asymmetric ion flow across the lipid membrane. Due to imbalance in the ion flow, the early lipid vesicles could selectively take the neces...
BIOMEX Experiment: Ultrastructural Alterations, Molecular Damage and Survival of the Fungus Cryomyces antarcticus after the Experiment Verification Tests [0.03%]
南极真菌Cryomyces antarcticus进行BIOMEX实验后的超微结构损伤、分子损伤和存活状况分析

The search for traces of extinct or extant life in extraterrestrial environments is one of the main goals for astrobiologists; due to their ability to withstand stress producing conditions, extremophiles are perfect candidates for astrobiol...
Reflected Light from Giant Planets in Habitable Zones: Tapping into the Power of the Cross-Correlation Function [0.03%]
适居带巨行星的反射光：利用交叉相关函数的力量

J H C Martins et al.
The direct detection of reflected light from exoplanets is an excellent probe for the characterization of their atmospheres. The greatest challenge for this task is the low planet-to-star flux ratio, which even in the most favourable case i...
Indicators and Methods to Understand Past Environments from ExoMars Rover Drills [0.03%]
从ExoMars探测 rover钻孔中了解过去环境的指标和方法

Great advances are expected during the analysis of drilled material acquired from 2 m depth by ExoMars rover, supported by the comparison to local context, and the joint use of different instruments. Textural information might be less detai...

With regard to the fascinating question of the origin of life, special interest has been devoted to potential prebiotic molecules which could drive the emergence of life. In the widely discussed hypothesis of a possible exogen apparition of...
Spontaneous Oligomerization of Nucleotide Alternatives in Aqueous Solutions [0.03%]
nucleoside类似物在水溶液中的自发聚合

Karen E Smith et al.
On early Earth, a primitive polymer that could spontaneously form from likely available precursors may have preceded both RNA and DNA as the first genetic material. Here, we report that heated aqueous solutions containing 5-hydroxymethylura...
The First Space-Related Study of a Kombucha Multimicrobial Cellulose-Forming Community: Preparatory Laboratory Experiments [0.03%]
首个关于菌菇多微生物纤维形成的社区的太空相关研究：预备实验室实验
