Cell Size01:22

Cell Size

114.6K
Cell sizes vary widely among and within organisms. Bacterial cells range between 1-10 micrometers (μm)and are considerably smaller than most eukaryotic cells. The smallest bacteria are 0.1 μm in diameter—about a thousand times smaller than eukaryotic cells, which typically range from 10-100 μm.
Surface Area
Cells can take in nutrients and water via diffusion through the plasma membrane itself or through specific channels in the membrane. The area of the membrane surrounding...

Prokaryotic Cells

122.3K
Prokaryotes are small unicellular organisms that include the domains—Archaea and Bacteria. Bacteria include many common organisms, such as Salmonella and E. coli, while the Archaea include extremophiles that live in harsh environments, such as volcanic springs.
Like eukaryotic cells, all prokaryotic cells are surrounded by a plasma membrane, have genetic material in the form of single, circular DNA, a cytoplasm that fills the interior of the cell, and ribosomes that synthesize proteins....

What are Cells?01:07

What are Cells?

175.6K
Cells are the smallest and basic units of life, whether it is a single cell that forms the entire organism, e.g., in a bacterium or trillions of them, e.g., in humans. No matter what organism a cell is a part of, they share specific characteristics.
Basic Characteristics of Cells
A living cell has a plasma membrane, a bilayer of lipids that separates the aqueous solution inside the cell called the cytoplasm from the outside environment.
Furthermore, a living cell possesses genetic information...

Evolutionary Relationships through Genome Comparisons

5.7K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Cells Coordinate Growth and Proliferation02:36

Cells Coordinate Growth and Proliferation

4.5K
Cell size is a significant factor impacting cellular design, function, and fitness. There exists some internal coordination by which cells double their masses before division, thus, achieving homeostasis. Coordination between cell growth and proliferation depends on the checkpoints in between cell cycle phases. Loss of coordination or failure in the checkpoint mechanism can drive the cell to uncontrolled growth and loss of cellular function. Like dividing cells that coordinate cellular growth,...

What is Cell Signaling?02:03

What is Cell Signaling?

117.7K
Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. Additionally, cells often need to communicate with one another. Unicellular and multicellular organisms use a variety of cell signaling mechanisms to communicate to respond to the environment.

Area of Science:

  • Physics
  • Medicine
  • Multidisciplinary Sciences

Background:

  • Increasing trend of mega-author publications (500+ authors) over the past two decades.
  • Challenges associated with mega-authorship include authorship verification, metadata issues, and publication length.
  • Identification of mega-author titles as a distinct category for analysis.

Purpose of the Study:

  • To investigate the phenomenon of mega-authorship in scientific publications.
  • To identify the scientific fields predominantly associated with mega-author articles.
  • To explore potential drivers and propose solutions for the challenges posed by mega-authorship.

Main Methods:

  • Utilized InCites to identify 5,533 mega-author items (≥500 authors).
  • Collected metadata for these items from Web of Science and Scopus databases.
  • Analyzed publication trends and correlated them with external scientific project timelines.

Main Results:

  • The vast majority of mega-author articles are concentrated in physics, with medicine as a distant second.
  • A significant correlation was observed between mega-authorship output and key events in the Large Hadron Collider's operational timeline.
  • Other scientific fields show only minor representation in mega-author publications.

Conclusions:

  • The Large Hadron Collider projects appear to be a primary driver of the surge in mega-authorship, particularly in physics.
  • Addressing the challenges of mega-authorship requires collaborative efforts and potential guideline revisions, possibly informed by bodies like the International Committee of Medical Journal Editors.
  • Further research is needed to fully understand and manage the implications of large-scale collaborative research on scientific publishing.
