Detecting nanoscale vibrations as signature of life [PDF]

open access: yesProceedings of the National Academy of Sciences, 2014
Significance The quest to find life in extreme and extraterrestrial environments is exciting and touches many research fields. One of the common signatures of life is movement: Even small microorganisms vibrate in response to their metabolic activity.

Immunological detection of small organic molecules in the presence of perchlorates: relevance to the life marker chip and life detection on Mars. [PDF]

open access: yes, 2011
The proposed ExoMars mission, due to launch in 2018, aims to look for evidence of extant and extinct life in martian rocks and regolith. Previous attempts to detect organic molecules of biological or abiotic origin on Mars have been unsuccessful ...

Biogenic Metal Nanoparticles: A New Approach to Detect Life on Mars?

open access: yesLife, 2020
Metal nanoparticles (MNPs) have been extensively studied. They can be produced via different methods (physical, chemical, or biogenic), but biogenic synthesis has become more relevant, mainly for being referred by many as eco-friendly and more ...

Microscopic Object Classification through Passive Motion Observations with Holographic Microscopy

open access: yesLife, 2021
Digital holographic microscopy provides the ability to observe throughout a volume that is large compared to its resolution without the need to actively refocus to capture the entire volume.

How to Detect Life on Icy Moons [PDF]

open access: yesAstrobiology, 2018
The icy moons of the outer Solar System present the possibility of subsurface water, habitable conditions, and potential abodes for life. Access to evidence that reveals the presence of life on the icy moons can be facilitated by plumes that eject material from the subsurface out into space.

Organic Catalytic Activity as a Method for Agnostic Life Detection. [PDF]

open access: yes, 2023
An ideal life detection instrument would have high sensitivity but be insensitive to abiotic processes and would be capable of detecting life with alternate molecular structures.

Association between polymorphisms of MIR17HG and risk of colorectal cancer in the Chinese Han population

open access: yesMolecular Genetics & Genomic Medicine, 2019
Background Colorectal cancer is the third most common cancer worldwide. Recently, an increasing number of evidences suggest that genetic susceptibility plays an important role in the occurrence of colorectal cancer.

pPolyHb protects myocardial H9C2 cells against ischemia-reperfusion injury by regulating the Pink1-Parkin-mediated mitochondrial autophagy pathway

open access: yesArtificial Cells, Nanomedicine, and Biotechnology, 2019
Mitochondrial dysfunction is a major contributory factor for myocardial ischemia-reperfusion (I/R) injury. It has been reported that Pink1-Parkin-mediated mitochondrial autophagy could effectively remove damaged mitochondria and excess ROS to ensure the ...

Way to the detection of Mars life.

open access: yesBiological Sciences in Space, 1996
In this review, I would like to introduce how we can detect the possible life on Mars. Even though the quantitative estimation of the possibility of biogenesis on Mars is difficult, Dr. McKay and his colleagues work has thrown a tiny light for this possibility. Considering Mars environmental conditions, the possible life is microorganisms.

A Test in a High Altitude Lake of a Multi-Parametric Rapid Methodology for Assessing Life in Liquid Environments on Planetary Bodies: A Potential New Freshwater Polychaete Tubeworm Community

open access: yesFrontiers in Environmental Science, 2019
On our planet, aqueous environments such as deep sea or high-altitude aphotic lakes, subject to present or past volcanic activity and active deglaciation, may provide analogs to the aqueous environments found on such planetary bodies as Europa, Titan or ...
