Research by University of California, Riverside physicist Roya Zandi reveals how viruses form highly symmetrical icosahedral structures around their genomes through a process of self-correction, driven by protein elasticity. This study could lead to designing synthetic nanocontainers for medical and biotech uses.
A new study in Nature Communications found that AI models exhibit a geometric property called convexity, which helps humans form and share concepts. Convexity is also linked to the performance of AI models on specific tasks.
A study discovers that traditional Chinese ice-ray lattice designs can provide unique stiffness and strength under asymmetric loads, offering an alternative to conventional gridshells. The research also explores the potential of integrating complex geometry into facade design and micro-scale material design.
Researchers in Namibia analyzed prehistoric rock art engravings of animal tracks and human footprints, revealing surprising details about the diversity of species represented. The findings suggest culturally determined preferences in the depiction of animals, with a preference for adult male footprints.
A team of scientists from Tokyo Metropolitan University created unprecedentedly lightweight optics for X-ray space telescopes by employing Micro Electro-Mechanical System (MEMS) technology. By refining the patterning and annealing process, they achieved ultra-sharp features that rival existing telescopes in performance while significan...
A team of scientists discovered a mathematical principle explaining how cells connect to form tissues and organs, shedding light on embryonic development and organ formation. The study found that epithelial cells can adopt complex three-dimensional shapes like scutoids, which determine cellular connectivity and tissue properties.
Researchers constructed a synthetic stub lattice in two coupled rings of different lengths, observing flat bands, band transitions and mode localization. This experimental demonstration enables dynamic control of light and may pave the way for future applications in optical communications.
Researchers have developed a 3D-printed design that mimics the behavior of auxetic materials, used to absorb and distribute impact forces. The design, made from bioplastic, can potentially replace steel and fiber-reinforced polymer mesh reinforcements in composites.
Scientists successfully produce and characterize a crystalline complex with a two-dimensional equivalent of silicon, defying geometric expectations. The resulting structure displays surprising physical and chemical properties, opening up new avenues for catalysis and materials research.
Researchers developed a computer program to create geometric shapes from video sequences, comparing them to participants' recounted experiences. The study found that people tend to remember major plot points accurately, while finer-scale details are distorted or forgotten.
Researchers found that hypnotic suggestions can help people 'see' imaginary objects, improving their ability to solve visual puzzles. Participants who were highly susceptible to hypnosis showed a significant improvement in accuracy after receiving the suggestion.
Researchers found that infants aged 12-15 months watched for longer when presented with incongruent speech patterns, suggesting they have formed expectations not only about infant-directed speech but also adult-directed speech. This study raises questions about the mechanisms of infants' expectations and social importance of different ...
A team of researchers has confirmed that distinctive geometric shapes and irregular amorphous structures can be identified mathematically in atomic clusters. The new method provides insights into the structural properties and potential forces between atoms, enabling more effective engineering of nanoparticles for specific applications.
Researchers have discovered over 100 massive stone jars in Laos, revealing more widespread use of these enigmatic containers than previously thought. The finds also include beautifully carved discs used as burial markers, showcasing intricate imagery including concentric circles, human figures, and creatures.
A CU Boulder-led study found that targeted training can improve spatial reasoning skills in young adults, increasing their performance in geoscience classes. After one semester, 70% of trained students showed significant improvement in spatial skills, with many reporting enhanced abilities in other science classes.
Researchers discover epithelial cells can adopt a new geometric shape called scutoid, allowing tissues to curve and form complex organs. This finding has significant implications for understanding organ development and potentially treating diseases related to altered tissue curvature.
A recent study found that cultural differences in visual processing affect the ability to discern simple differences between geometric figures. North Americans took longer to identify a straight line among tilted ones compared to Japanese volunteers.
A study found that seating arrangements impact consumers' responses to persuasive messages, with circular arrangements favoring belonging-based messaging and angular arrangements favoring uniqueness-based messaging. This knowledge can inform various settings, such as restaurants and public transit.
Scientists at Northwestern University have developed a method to recreate unique shell geometries in lab-made microcompartments by altering the acidity of their surroundings. This breakthrough could lead to designed microreactors that mimic cellular functions or deliver therapeutic materials to cells.
Researchers have developed a new method for describing extremely complicated shapes, bridging topology and fractals. The persistent homology theory will aid in investigating and describing complex structures found in nature, such as defects in metals and wave froth.
A study by Joseph P. Redden and Stephen J. Hoch found that variety in optical illusions leads to underestimation of quantity, causing individuals to pour more when faced with a mix of items. This perception affects food portions and may contribute to overeating.
A team of University of Pennsylvania physicists creates a simple system to study and control geometric frustration using micron-sized spheres in water. They found that the lattice deforms to relieve frustration as the material becomes more strongly frustrated.
A study by University of Iowa authors found that consumers have a bias for the whole, preferring larger bills due to processing fluency. This affects their willingness to use smaller bills, as they associate value with larger bills.
The Munduruküul community in Brazil shows competence with basic concepts of topology, Euclidean geometry, and geometrical figures, even children as young as six years old performed well. The study suggests that core geometrical knowledge is a universal constituent of the human mind, independent of formal education or cultural devices.
A study by Ohio State University researchers found that participants were more likely to incorrectly identify a similar image as part of the original set, even though it was not present. This suggests that visual false memories can be induced using context, challenging our perceptions and memory recall.
