Summary
Organism motor synchrony significantly varies with daily temperature cycles, revealing a robust link between biological rhythms and environmental adaptation. This highlights the interconnectedness of organism-environment systems.
Area of Science:
- Chronobiology
- Human Physiology
- Environmental Science
Background:
- Understanding organism-environment interactions is crucial for biological autonomy.
- End-directed biological capabilities are influenced by environmental cycles.
- Circadian rhythms play a key role in physiological regulation.
Purpose of the Study:
- To investigate the relationship between biological characteristics and environmental cycles.
- To uncover the laws governing end-directed capabilities.
- To measure motor synchrony in relation to circadian temperature cycles.
Main Methods:
- Assessed biological autonomy and control of function.
- Measured motor synchrony as a biological characteristic.
- Utilized circadian temperature as an environmental cycle.
Main Results:
- Bimanual coordination stability significantly varied with the day-night temperature cycle.
- Circadian effects on motor synchrony were observed.
- The ratio of circadian effect to ordinary circadian rhythm remained constant.
Conclusions:
- A direct and robust relationship exists between biological characteristics (body temperature, motor synchrony) and environmental processes (circadian temperature cycle).
- This relationship may reflect the adaptation of biological systems to their environment.
- The findings support the importance of the organism-environment system in understanding biological control.

4.1K
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...

01:34Woodward–Hoffmann Selection Rules and Microscopic Reversibility
3.2K
Electrocyclic reactions, cycloadditions, and sigmatropic rearrangements are concerted pericyclic reactions that proceed via a cyclic transition state. These reactions are stereospecific and regioselective. The stereochemistry of the products depends on the symmetry characteristics of the interacting orbitals and the reaction conditions. Accordingly, pericyclic reactions are classified as either symmetry-allowed or symmetry-forbidden. Woodward and Hoffmann presented the selection criteria for...

01:28Symmetry in Maxwell's Equations
3.5K
Once the fields have been calculated using Maxwell's four equations, the Lorentz force equation gives the force that the fields exert on a charged particle moving with a certain velocity. The Lorentz force equation combines the force of the electric field and of the magnetic field on the moving charge. Maxwell's equations and the Lorentz force law together encompass all the laws of electricity and magnetism. The symmetry that Maxwell introduced into his mathematical framework may not be...

In mechanical engineering, one-degree-of-freedom systems form the basis of a wide range of electrical and mechanical components. Using these models, engineers can predict the behavior of various parts in a larger system, which gives them insight into how different forces interact with each other.
A one-degree-of-freedom system is defined by an independent variable that determines its state and behavior. One example of a one-degree-of-freedom system is a simple harmonic oscillator, such as a...

01:04Oscillations about an Equilibrium Position
5.5K
Stability is an important concept in oscillation. If an equilibrium point is stable, a slight disturbance of an object that is initially at the stable equilibrium point will cause the object to oscillate around that point. For an unstable equilibrium point, if the object is disturbed slightly, it will not return to the equilibrium point. There are three conditions for equilibrium points—stable, unstable, and half-stable. A half-stable equilibrium point is also unstable, but is named so...

01:19Cyclic Processes And Isolated Systems
2.8K
A thermodynamic system with zero heat exchange and work is an isolated system. For these systems, the internal energy remains constant.
In the case of a non-isolated system, the change in the internal energy is zero only if the process is cyclic. A thermodynamic process is considered cyclic if the system undergoes a series of changes and returns to its initial state.
Consider a cyclic process that returns to its initial state, undergoing a four-step process. The heat transfer along each...
