The use of origami in engineering and materials science is prevalent, particularly in the development of mechanical metamaterials. These materials derive their properties from their geometry rather than their base material, allowing them to have tunable characteristics like Poisson’s ratio, thermal expansion, and stiffness. Origami-based materials can adapt their properties after being made, making them useful in various engineering fields.
- “One challenge is that current origami metamaterials exhibit nonlinear mechanical behavior, making it hard to achieve a constant Poisson’s ratio. To address this, researchers designed origami structures that maintain a near-constant Poisson’s ratio by using specific patterns, such as the Morph origami pattern. This innovation could lead to improved designs for applications like deployable space structures, medical devices, and even cinema acoustics. Prof. Glaucio Paulino praised the study, highlighting its potential impact on deployable systems for space exploration and medical devices, and even its possible applications in the entertainment industry for sound control.”

Poisson's ratio is a measure of how a material deforms in directions perpendicular to the direction of applied force. It is used to describe the elastic behavior of materials when they are stretched or compressed. When a material is stretched in one direction, it typically becomes thinner in the perpendicular directions, and when it is compressed, it becomes thicker. Poisson's ratio quantifies this behavior and is calculated as the ratio of the lateral strain (deformation in the perpendicular direction) to the axial strain (deformation in the direction of the applied force). Poisson's ratio is essential in designing materials and structures to ensure they perform as expected under various forces, helping predict deformation in engineering and scientific applications.

The Morph origami pattern can be applied in the entertainment industry, particularly in sound control, due to its unique ability to change shape and geometry, which can directly influence how sound waves are absorbed, reflected, or directed in a space. How it works and how it can be useful:
-
Adjustable Acoustic Panels:
- The Morph origami pattern can be used to create acoustic panels that change their surface structure based on the acoustic needs of a room, such as a cinema hall, concert venue, or recording studio. These panels can be folded and unfolded to control the reflection and absorption of sound, adjusting the acoustics in real time. For example, during a movie or musical performance, these panels can adapt to either enhance speech clarity or balance musical tones by changing their fold configuration.
-
Tunable Sound Reflection and Absorption:
- The geometry of the Morph pattern allows it to control how sound waves interact with surfaces. By modifying the pattern's configuration, the origami structure can absorb certain sound frequencies while reflecting others, enabling precise tuning of acoustics for different performances or environments. This makes it useful in settings like cinemas or theaters, where sound quality is critical. For example, the pattern can be adjusted to reduce echoes and enhance speech clarity in dialogue-heavy scenes, or to create richer, more immersive sound experiences during action sequences.
-
Customized Soundscapes:
- The folding and unfolding capabilities of Morph origami patterns could enable real-time acoustic changes during a performance or screening. This flexibility allows the design of customizable soundscapes where the acoustic environment adapts to the content being shown. For instance, a theater could use Morph-patterned panels to shift the sound dynamics for different movie genres or live performances. For an audience, this could mean a more personalized listening experience, where sound is controlled more precisely, providing optimized audio based on the seating area, performance type, or audience size.

(Science) ABO blood groups
- The ABO blood group system is one of the most important classifications in human biology. It categorizes blood based on the presence or absence of specific antigens (A and B) on the surface of red blood cells and corresponding antibodiesin the plasma.
-
Blood Group Types
-
How It Works
-
Compatibility in Transfusions:
- Matching blood types is critical during transfusions to prevent hemolysis (destruction of red blood cells) caused by an immune reaction.
- Mismatched transfusions lead to severe complications, as the recipient's antibodies attack the donor's red blood cells → can sometimes be fatal.
-
-
Uses of ABO Blood Grouping
- Medicine:
- Blood Transfusions: Ensures safe blood matches during surgeries, trauma, or childbirth.
- Organ Transplants: Prevents rejection by matching blood types between donor and recipient.
- Pregnancy Monitoring: In cases of hemolytic disease of the newborn, understanding ABO incompatibilities between mother and fetus is crucial.
- Forensic Science:
- Used to exclude suspects in crime investigations, especially before DNA profiling became widespread.
- Anthropology and Population Genetics:
- Studying the distribution of ABO blood groups can provide insights into genetic evolution, migration patterns, and disease susceptibility in populations.
