Article Synopsis
- The term "biosignature" is crucial in astrobiology, linking observations to possible biological causes, but its definitions vary across scientific communities.
- There are concerns that current definitions may overstate certainty and create confusion, especially since the distinction between life and non-life is not always clear.
- The authors propose that scientists should be cautious with the term, define it explicitly, and use a checklist for evaluating biosignature claims to enhance communication and understanding in the field.
Article Synopsis
- The study aimed to assess the prevalence of long COVID and its effects on farmworkers in California, focusing on a sample of 297 individuals between February and July 2022.
- Findings revealed that 61.8% of farmworkers with a suspected or confirmed COVID-19 infection experienced long COVID symptoms lasting more than 28 days, with affected individuals showing higher body mass index (BMI) and inflammatory markers.
- The research underscored the need for tailored support for farmworkers experiencing long COVID, highlighting their persistent health issues that hinder their work capabilities in this essential industry.
Homochirality is a generic and unique property of all biochemical life and it is considered a universal and agnostic biosignature. Upon interaction with unpolarized light, homochirality induces fractional circular polarization in the light that is scattered from it, which can be sensed remotely. As such, it can be a prime candidate biosignature in the context of future life detection missions and observatories.

The potential exists for similar processes to operate on habitable exoplanets and result in observable biosignatures. Before the advent of oxygenic photosynthesis, the most primitive phototrophs, anoxygenic phototrophs, dominated surface environments on the planet.

Purpose: The purpose of this study was to determine the incidence of NV-HAP in a California community hospital and to identify the patient and nursing care factors including missed nursing care associated with its development.
Methods: A retrospective study identified possible NV-HAP cases with ICD-10 (International Classification of Diseases, Tenth Revision) codes and then validated cases using Centers for Disease Control and Prevention confirmatory criteria.
