AI Article Synopsis

  • The "RNA world" hypothesis, which suggests that life began with ribozymes, is currently the leading theory about the origin of life and genetic information.
  • However, this hypothesis has limitations that need to be addressed.
  • To explore alternatives, researchers are considering theories related to the hydrothermal origin of life, the solubility of RNA and similar biopolymers, and creating evolutionary systems similar to in vitro selection methods for functional RNA based on molecular biology.

Article Abstract

Following the discovery of ribozymes, the "RNA world" hypothesis has become the most accepted hypothesis concerning the origin of life and genetic information. However, this hypothesis has several drawbacks. Verification of the hypothesis from different viewpoints led us to proposals from the viewpoint of the hydrothermal origin of life, solubility of RNA and related biopolymers, and the possibility of creating an evolutionary system comparable to the in vitro selection technique for functional RNA molecules based on molecular biology.

Proteolysis targeting chimeras (PROTACs) are bifunctional molecules that induce selective protein degradation by linking an E3 ubiquitin ligase enzyme to a target protein. This approach allows scope for targeting "undruggable" proteins, and several PROTACs have reached the stage of clinical candidates. However, the roles of cellular transmembrane transporters in PROTAC uptake and efflux remain underexplored.

Particle emissions study from tire sample with nano-silver tracer from different steps of its life cycle. A new approach to trace emissions of tire microparticles.

Direction Milieux et impacts sur le vivant, Institut National de l'Environnement Industriel et des Risques (INERIS), Verneuil en Halatte, France.

Emissions due to tires retread/repair and incineration are a cause of concern owing to the presence of nanoparticles in the products. The assessment exposure to humans hereto related is a challenge in an environmental context. The first object of this work is to develop a method to characterize the emission sources using online (counting and sizing) and offline measurements.

Ecotoxicology of cephalopod early life phases: review and perspectives.

January 2025

Instituto Politécnico Nacional, Centro Interdisciplinario de Ciencias Marinas, Av. Instituto Politécnico Nacional S/N, Playa Palo de Santa Rita, C.P. 23096, La Paz, Baja California Sur, Mexico.

The present review provides the first analysis and synthesis of the available scientific information on the effects of anthropogenic contaminants on cephalopod embryos, paralarvae, and juveniles. We evaluated 46 articles published between 1970 and 2023 that focused on trace elements (69%), pharmaceutical compounds (11%), persistent organic compounds (11%), and plastics (9%). To date, the greatest scientific effort has originated from Europe and Asia (France [57%], China [9%], Italy [7%], and Spain [4%]), with few reports available from the rest of the world.

The hominin mandible SK 15 was discovered in April 1949 in Swartkrans Member 2, dated to ∼1.4 Ma. Albeit distorted on the right side, the left and right corpus of SK 15 are relatively low and thick, even compared to most Early to Middle Pleistocene Homo specimens.
