New models shed light on life"s origin
The first signs of life emerged on Earth in the form of microbes about four billion years ago. While scientists are still determining exactly when and how these microbes appeared, it's clear that the emergence of life is intricately intertwined with.....»»
Tracing the origin of life—a new abiotic pathway for the formation of peptide chains from amino acids
A team of scientists from France and Austria has discovered a new abiotic pathway for the formation of peptide chains from amino acids—a key chemical step in the origin of life. The current study provides strong evidence that this crucial step for.....»»

Researchers measure boron flux in high-energy cosmic rays with the CALorimetric Electron Telescope (CALET)
Cosmic rays (CR) constitute high-energy particles that mainly originate outside our solar system. These primary CR interact with interstellar matter to produce secondary CR. The secondary nature of their origin is reflected in the higher abundance of.....»»
Social work researchers examine the health impacts of US immigration policy
Immigration is one of the most controversial social and political issues in American life. Yet little attention is given to the aftermath of U.S. immigration policies or the immigrant Americans who are deported back to their country of origin. What i.....»»
Study investigates kinematics and origin of gas in the galaxy NGC 2655
Using the 6-meter telescope of the Special Astrophysical Observatory (SAO) and the 2.5-meter telescope of the Caucasian Mountain Observatory (CMO), Russian astronomers have observed a giant galaxy known as NGC 2655. Results of the observational campa.....»»
Study suggests a paradigm shift in our understanding of gamma ray bursts
Matter outflows in the form of jets are observed in astronomical systems at fast, medium and slow speeds. The fastest jets are highly relativistic, and travel very close to the speed of light. The origin, as well as many properties of the jets, is un.....»»
Origin of endothelial cells constituting the vascular niche for hematopoietic stem and progenitor cells in zebrafish
Endothelial cells (ECs) line blood vessels and can serve as specialized vascular niches for hematopoietic stem and progenitor cells (HSPCs), a special environment where HSPCs reside and self-renew. A team of researchers found that endoderm-derived EC.....»»
