RNA-seq03:21

RNA-seq

11.7K
RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases. 
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while...

Emission Spectra02:39

Emission Spectra

75.4K
When solids, liquids, or condensed gases are heated sufficiently, they radiate some of the excess energy as light. Photons produced in this manner have a range of energies, and thereby produce a continuous spectrum in which an unbroken series of wavelengths is present.

Multi-species Conserved Sequences

4.6K
Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale  studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved...

Atomic Emission Spectroscopy: Overview01:20

Atomic Emission Spectroscopy: Overview

3.4K
Atomic emission spectroscopy (AES) is an analytical technique used to determine the elemental composition of a sample by analyzing the light emitted from excited atoms. In AES, atoms in a sample are excited to higher energy levels by thermal energy from high-temperature sources, such as plasma, arcs, or sparks. When these excited atoms return to lower energy states, they emit light at specific wavelengths characteristic of each element. The resulting atomic emission spectrum, which consists of...

Additional Subnuclear Structures

5.2K
The eukaryotic nucleus is a double membrane-bound organelle that contains nearly all of the cell’s genetic material in the form of chromosomes. It is rightly called the “brain” of the cell as it shoulders the responsibility of responding to various physiological processes, stress, altered metabolic conditions, and other cellular signals. 
The nucleus contains many membrane-less subnuclear organelles or nuclear bodies, such as nucleoli, Cajal bodies, speckles,...

Area of Science:

  • Astronomy and Astrophysics
  • Stellar Evolution
  • Star Cluster Dynamics

Background:

  • Extended main sequences (eMSs) and extended main-sequence turn-offs (eMSTOs) are observed in star clusters.
  • These phenomena contradict the canonical simple stellar population model, which assumes coeval and chemically homogeneous stars.

Purpose of the Study:

  • To review the observational characteristics, mechanisms, and implications of eMSs and eMSTOs.
  • To evaluate proposed hypotheses, including age spread, binary interactions, variable stars, and stellar rotation.

Main Methods:

  • Comprehensive literature review of observational data and theoretical models.
  • Analysis of proposed hypotheses for eMS and eMSTO formation.
  • Evaluation of the plausibility of stellar rotation as the primary mechanism.

Main Results:

  • Stellar rotation is identified as the most plausible mechanism explaining eMSs and eMSTOs.
  • Other hypotheses like age spread and binary interactions are discussed with their limitations.
  • The review highlights the significance of stellar rotation in understanding cluster evolution.

Conclusions:

  • Stellar rotation provides a robust explanation for eMSs and eMSTOs, challenging previous models.
  • Research into stellar rotation opens new avenues, including magnetic braking and binary mergers.
  • These findings significantly advance our understanding of stellar astrophysics and star cluster evolution.
