Muscles that Move the Arm01:31

Muscles that Move the Arm

4.9K
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

Molecular Shapes

62.5K
Molecules have characteristic shapes that are crucial for their function. The arrangement of various electron groups around the central atom dictates their molecular geometry. Electron pairs in the valence shell of a central atom will adopt an arrangement that minimizes repulsions between the electron pairs by maximizing the distance between them. The valence electrons form either bonding pairs, located primarily between bonded atoms, or lone pairs.
Two regions of electron density in a diatomic...

Global Climate Change

29.1K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Rates of Change

143
The rate of change is a central concept in mathematics that quantifies how one variable varies in response to another. It serves as a foundational tool in modeling dynamic systems across disciplines such as physics, biology, economics, and engineering. Understanding both average and instantaneous rates of change enables the analysis of behavior in functions that describe real-world phenomena.Average Rate of ChangeFor a function f(x) defined over an interval [x1,x2], the average rate of change...

Area of Science:

  • Artificial life
  • Biophysics
  • Chemical self-organization

Background:

  • Protocells are model systems that replicate cellular functions.
  • Decanol droplets in sodium decanoate solutions exhibit cell-like behaviors.
  • Evaporation-induced morphological changes in protocells are not well understood.

Purpose of the Study:

  • To investigate shape changes in decanol-decanote protocells induced by water evaporation.
  • To analyze the reversibility and self-avoidance of these morphological transformations.
  • To discuss the implications for the study of artificial life.

Main Methods:

  • Formation of decanol droplets in aqueous sodium decanoate and salt solution.
  • Induction of shape changes via controlled water evaporation.
  • Microscopic observation and analysis of protocell morphology and dynamics.

Main Results:

  • Decanol droplets undergo complex, branching shape transformations mimicking cellular growth.
  • Morphological changes were observed to be reversible upon rehydration.
  • Protocells demonstrated self-avoidance behavior during shape transformation.

Conclusions:

  • Evaporation-driven morphological changes offer a novel mechanism for protocell development.
  • Reversibility and self-avoidance suggest sophisticated self-organization principles.
  • These findings contribute to understanding the origins and development of artificial life.
