Harvard physicists develop an optical vortex beam that twists and changes shape, resembling spiral shapes found in nature. The 'optical rotatum' has potential applications in controlling small particles and micro-manipulation, and its creation is made possible with a single liquid crystal display.
UCLA doctoral student Yilin Wong noticed spiral patterns on her Germanium chip sample after leaving it overnight. The patterns were influenced by residual stress in the metal film, with different changes in experiment parameters generating various shapes.
A team of astronomers has obtained detailed images of a small galaxy and its surroundings, revealing features typically associated with larger galaxies. The study found that the mechanisms fueling galaxy growth may be more universal than previously thought, suggesting that even dwarf galaxies can build stellar halos through accretion.

A team of researchers discovered that twisting layers of a material can generate an electron-path-deflecting effect, controlling light and electrons in quantum materials. The phenomenon mimics the Coriolis force, where light is used to manipulate electrons, exhibiting new quantum behaviors.
A new study reveals how sika deer foraging is causing soil erosion, reducing the growth of Japanese beech trees. The research found that exposed roots are more vulnerable to water loss, affecting tree health and increasing vulnerability to climate change and pests.
Researchers at MIT find that slow-flowing liquid crystals can spontaneously assemble into large, twisted, chiral structures, opening a new path to generating chiral materials. These structures could serve as spiral scaffolds for assembling intricate molecular structures and be used as optical sensors.
Researchers have implemented Orbital Angular Momentum (OAM) as an independent information carrier for optical holography, leading to OAM multiplexed holography. The new design approach, MHC-OAM, uses spatial light modulators to achieve multiramp helical conical beams with different parameters serving as information encryption or decryp...
Researchers at UW-Madison develop a method to control the growth of twisting, microscopic spirals of two-dimensional materials. By utilizing screw dislocations and curved surfaces, they create new properties that can be exploited to study quantum physics on the nanoscale.

A team of scientists at OIST Graduate University found an unexpected spiral vortex phenomenon when liquid flows through the intersection of two channels. The researchers discovered that spirals appear as flow rates increase and disappear with decreased rates, exhibiting hysteresis in devices with large aspect ratios.
Researchers Jan Boeyens and Francis Thackeray found a connection between the Golden Ratio, space-time, and a biological species constant. The study suggests that concepts associated with relativity and quantum mechanics can be integrated through the number 1.618.
Scientists have identified two distinct patterns in cell membranes: spiral and uniform. The patterns are formed by highly organized lipids and vary according to temperature and lipid molecule type. Further research is needed to understand the significance of these patterns for biological functionality.

The Ras oncogene's suppression of p53 could explain why some cancers are resistant to radiation therapy. The finding suggests that Ras may play an indirect role in many more cancers by regulating the tumor-suppressor gene, contributing to cancer development.
Astronomers use NASA's Chandra X-ray Observatory to study the growth of Perseus A, a supergiant galaxy at the center of a large galaxy cluster. The research reveals that Perseus A has accumulated hundreds of billions of stars by cannibalizing gas and smaller galaxies in the vicinity.
Researchers created a wax experiment that replicates ocean floor spreading, allowing them to study millions of years of geological time. The experiments revealed the formation of microplates, tiny chunks of solid wax that roll up and rotate in a spiral shape, mirroring the Earth's natural phenomenon.
