According to SciTechDaily, “Stranger Than Friction: An Invisible Force Initiating Life” is a study that reveals how sea squirt oocytes use internal friction to undergo developmental changes after conception. The study draws a parallel to a potter shaping clay.
The study examines how friction forces propel development in a marine organism. It also explores how scientists can reach for the stars and uncover the missing precursors of hydrogen
The findings suggest that friction forces play a crucial role in reshaping and reorganizing the insides of ascidian oocytes after fertilization. This heralds the next steps in their developmental cascade
The study provides novel insight into how mechanical forces determine cell and organismal shape. It shows that friction forces are pivotal for shaping and forming an evolving organism. However, scientists are only at the beginning of understanding the specific role of friction in embryonic development
An Invisible Force Initiating Life” is a study that reveals how sea squirt oocytes use internal friction to undergo developmental changes after conception. The study was published in Nature Physics by the Heisenberg group at the Institute of Science and Technology Austria (ISTA).
The study found that friction forces within the oocytes play a crucial role in reshaping and reorganizing their insides. This leads to the formation of a bell-like protrusion called the contraction pole (CP). The CP is a crucial structure where essential materials gather to facilitate the embryo’s maturation.
The researchers studied tiny sea squirt eggs (ascidian oocytes) under a microscope. They found that after the eggs were fertilized, changes happened inside them, leading to the creation of a special structure called the contraction pole.
Sea squirts are marine animals with some primitive vertebrate features. They are primarily sessile (permanently fixed to a surface), potato-shaped organisms found in all seas, from the intertidal zone.
The study, titled “Stranger than Friction: A Force Initiating Life”, was published in Nature Physics by the Heisenberg group at the Institute of Science and Technology Austria (ISTA). The study describes how friction forces are used by sea squirts to change and develop after fertilization.
The Heisenberg group is a research group at ISTA that is dedicated to studying the physical and chemical processes that occur in living organisms. The group is led by Professor Tilman Sauer, who is an expert in the field of biophysics.
The study was conducted by a team of scientists led by Dr. Michael Toskovic. The scientists used a combination of experimental and computational methods to study how friction forces are used by sea squirts. They found that friction forces are essential for the development of sea squirts, and that these forces play a role in a variety of processes, including fertilization, cell division, and tissue formation.
The study’s findings have important implications for our understanding of how living organisms develop. They also suggest that friction forces may play a role in other biological processes, such as the development of cancer and the healing of wounds.
According to a recent study published in Nature Physics, friction forces play a crucial role in reshaping and reorganizing the insides of ascidian oocytes upon fertilization. This research was conducted by the Heisenberg group at the Institute of Science and Technology Austria (ISTA).
Oocytes are female germ cells that are involved in reproduction. Friction forces are a force that resists the sliding or rolling of one solid object over another.
The study found that friction forces between the actomyosin cortex and the myoplasm cause the myoplasm to fold and create bumps. When the actomyosin movement stops, the bumps turn into the contraction pole.
Friction is a force that resists motion when the surface of one object comes in contact with the surface of another. Frictional forces can be beneficial, but they also present a great measure of opposition to motion
The findings suggest that upon fertilization of ascidian oocytes, friction forces play a crucial role in reshaping and reorganizing their insides, heralding the next steps in their developmental cascade. Oocytes are female germ cells involved in reproduction
According to EurekAlert!, friction forces play a key role in reshaping and reorganizing the insides of oocytes after fertilization. This process sets the stage for the embryo’s subsequent development
Oocytes are female germ cells involved in reproduction. They are immature egg cells, or ova, that are produced in the ovaries during female gametogenesis. During the follicular phase and again during ovulation, oocytes mature and divide, becoming mature ova or eggs.
The developmental route of an oocyte with functional ability includes the following steps:
- Gastrulation
- Epiblast cells formation
- Primordial germ cell
- Gonocyte
- Oogonium
- Primary oocyte
- Secondary oocyte
- Antral follicle
- Mature oocyte
