Fatigue-crack Formation In Samples From Asteroid Bennu And Petrologic Controls On Boulder Properties And Evolution
Thermal fatigue has been observed to be an important driver of boulder evolution on asteroid Bennu through the development of morphological features such as exfoliation flakes and linear fractures in […]
Tricks of Nature From the Ancient Earth and Early Mars: Chemical Gardens Generate Biomorphs With High Preservation Potential
Observations of morphology are commonly used to evaluate the biogenicity of terrestrial microfossils and could constitute a crucial line of evidence for extraterrestrial life‐detection missions in the future.
Analysing The Sample Preparation Process In Meteorites And Its Impact On The Pretreatment Of Returned Samples To Earth
The study of meteorites is important for planetary sciences because, among other things, it can provide information about the geochemical composition of their celestial body of origin. Often, subsample preparation […]
Discovery Of Unexpectedly Large Organic Molecules from Asteroid Ryugu
Overview Using a high-resolution atomic force microscope ( AFM ), we directly observed the skeletal structures of individual organic molecules extracted from the Ryugu sample. We discovered numerous gigantic organic […]
Tricorder Tech: A Non-Invasive, Label-Free Method for Examining Tardigrade Anatomy Using Holotomography
Background/Objectives: Holotomography is an advanced imaging technique that enables high-resolution, three-dimensional visualization of microscopic specimens without the need for fixation or staining.
Self-assembled Versus Biological Pattern Formation In Geology
Both abiotic self-organization and biological mechanisms have been put forward as the origin of a number of geological patterns.
Deep Learning For Microbial Life Detection In Deep Subseafloor Samples: Objective Cell Recognition
Microscopic detection and enumeration of microbial biomass provide essential primary information about the biosphere.
Extreme Engineering – Unlocking Design Secrets of Deep-sea Microbes
The microbe Pyrodictium abyssi is an archaeon — a member of what’s known as the third domain of life — and an extremophile. It lives in deep-sea thermal vents, at […]
Tricorder Tech: Alien Carousel – In Situ Life Detection On Icy Moons With A Single-actuator Holographic Microfluidic Platform
Enceladus, one of Saturn’s moons, is considered one of the most promising places in the solar system to find life.
