Resumen
Los investigadores demostraron la transducción dinámica del comportamiento en materiales autónomos parecidos a la vida. Los coloidosomas autooscilantes mostraron oscilaciones quimiomecánicas a través de niveles jerárquicos, allanando el camino para nuevos diseños de materiales.

- Ciencia de los materiales Ciencia de los materiales.
- Ingeniería Química Ingeniería Química.
- Física de la materia blanda Física de la materia blanda
Sus antecedentes:
- Los materiales jerárquicos imitan a los sistemas vivos, integrando múltiples niveles organizativos para comportamientos complejos.
- Comprender la transducción dinámica del comportamiento a través de estos niveles en materiales sintéticos es un desafío clave.
- Los materiales autónomos parecidos a la vida real ofrecen nuevas posibilidades para sistemas receptivos y adaptativos.
Objetivo del estudio:
- Demostrar la transducción interjerárquica de comportamientos dinámicos en materiales sintéticos.
- Investigar los coloidosomas autooscilantes como un sistema modelo para el estudio de comportamientos emergentes.
- Identificar los mecanismos de la transducción quimiomecánica en materiales fuera de equilibrio.
Principales métodos:
- Se utilizaron coloidosomas autooscilantes compuestos de microgeles autooscilantes.
- Se han investigado las oscilaciones autónomas de floculación/dispersión impulsadas por la reacción de Belousov-Zhabotinsky.
- Se analizaron las oscilaciones de hinchazón/deshinchazón y deformación de forma bajo condiciones fuera de equilibrio.
Principales resultados:
- Identificó la transducción quimiomecánica a través de niveles jerárquicos en coloidosomas autooscilantes.
- Se observaron oscilaciones estocásticas de hinchazón/deshinchazón o deformación de la forma originadas por oscilaciones a nivel de microgel.
- Se determinó que los modos de oscilación del microgel constituyente dictan el comportamiento de oscilación macroscópica emergente.
Conclusiones:

12.7K
In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...

Unlike mitosis, meiosis aims for genetic diversity in its creation of haploid gametes. Dividing germ cells first begin this process in prophase I, where each chromosome—replicated in S phase—is now composed of two sister chromatids (identical copies) joined centrally.
The homologous pairs of sister chromosomes—one from the maternal and one from the paternal genome—then begin to align alongside each other lengthwise, matching corresponding DNA positions in a process...

01:16Transduction
1.8K
Among the three main modes of HGT—transformation, conjugation, and transduction—transduction is unique in that it is mediated by bacteriophages, or bacterial viruses.Transduction occurs in two ways. Generalized transduction occurs during the lytic cycle of a bacteriophage infection. In this process, bacteriophages infect bacterial cells, replicate within them, and ultimately cause cell lysis, releasing newly assembled virions. Occasionally, random fragments of the bacterial genome...

01:30Oscillations In An LC Circuit
3.2K
An idealized LC circuit of zero resistance can oscillate without any source of emf by shifting the energy stored in the circuit between the electric and magnetic fields. In such an LC circuit, if the capacitor contains a charge q before the switch is closed, then all the energy of the circuit is initially stored in the electric field of the capacitor. This energy is given by

01:06Forced Oscillations
8.0K
When an oscillator is forced with a periodic driving force, the motion may seem chaotic. The motions of such oscillators are known as transients. After the transients die out, the oscillator reaches a steady state, where the motion is periodic, and the displacement is determined.

01:07Damped Oscillations
7.3K
In the real world, oscillations seldom follow true simple harmonic motion. A system that continues its motion indefinitely without losing its amplitude is termed undamped. However, friction of some sort usually dampens the motion, so it fades away or needs more force to continue. For example, a guitar string stops oscillating a few seconds after being plucked. Similarly, one must continually push a swing to keep a child swinging on a playground.
