Van Gogh’s brushstrokes in “The Starry Night” create an illusion of sky movement so convincing it led researchers to wonder how closely it aligns with the physics of real skies. Marine sciences and fluid dynamics specialists analyzed the painting to uncover what they call the hidden turbulence in the artwork.
Many childhoods have been shaped by the works of Maurice Sendak, whose deeply emotional stories and fantastical illustrations have captured the imaginations of millions.
James Joyce’s tome “Finnegans Wake” famously breaks the rules of normal prose through its unusual, dreamlike stream of consciousness, and new work in chaos theory takes a closer look at how Joyce’s challenging novel stands out mathematically.
Martian landers have been able capture measurements of wind speeds — some gauging the cooling rate of heated materials when winds blow over them, others using cameras to image “tell-tales” that blow in the wind — but there’s still room for improvement.
In Physics of Fluids, researchers have started to unravel the mysteries of how near-horizontal bowling in cricket leads to such tough-to-hit balls. The team employed a wake survey rake device made of multiple tubes designed to capture the pressure downstream of the ball and examined the flow dynamics of cricket balls rotating up to 2,500 rpm in a wind tunnel. The group found that low-pressure zones expanded and intensified near the ball when spinning, while these zones shifted and diminished downstream. At higher spin rates, the low-pressure zone begins to change to a persistent bilobed shape. The results lend support to the theory that these newer bowling techniques tap into the Magnus effect.
Jatinder Palta, PhD, FAAPM, FASTRO, FACR, has been appointed as the first director to lead the Medical Physics Institute within the American Association of Physicists in Medicine. MPI was approved by the AAPM Board of Directors in 2023 to improve the quality and safety of patient care in radiology and radiation oncology.
In AIP Advances, researchers from Shandong Normal University develop a new type of rumor propagation model, taking inspiration from nuclear reactions. Their model can provide fresh insights on how online disinformation spreads and how to combat it.
In APL Materials, researchers from Lyuliang University have developed a low-cost, flexible, and customizable sensor for badminton players that overcomes current monitoring constraints. The team used triboelectric sensors to construct their intelligent monitoring system because they are easy to adapt for flexible, wearable devices and to minimize interference during bending and twisting, they built a 3D-printed flexible arch-shaped sensor encased in a thermoplastic elastomer. This design is comfortable during use and can be easily customized to individual athletes.
Faced with the world’s impending freshwater scarcity, researchers in Singapore turned to solar steam generators, which are emerging as a promising device for seawater desalination. The team sought design inspiration from trees and harnessed the potential of 3D printing.
In Physics of Fluids, researchers examine the specific impacts of microplastics on the geophysics of sea foam formation in the critical zone where water meets air in the top layer of the ocean.
A team of researchers had already been working with electricity price data for years before Russia’s invasion of Ukraine, exploring statistics and developing forecasting methods. Now they zero in on how prices in different countries relate and how countries were affected by the energy crisis and address the interdependencies of different markets.
The 74th ACA Meeting will take place July 7-12 at the Denver Marriott Tech Center. From developing new drugs, to engineering novel materials for electronics, to guiding unprecedented vaccines and biological insights, ACA2024 will highlight the golden future for structural science and bring together a diverse community of experts from around the world to share scientific discoveries and advancements that impact economies, health care, and everyday understanding of the natural world.
In AIP Advances, researchers have developed a new method for detecting foodborne pathogens that is faster, cheaper, and more effective than existing methods. Their microfluidic chip uses light to detect multiple types of pathogens simultaneously and is created using 3D printing, making it easy to fabricate in large amounts and modify to target specific pathogens.
In Applied Physics Reviews, researchers from Tsinghua University work to break through the difficulties of robotic recognition of various common, yet complex, items. Their layered sensor is equipped with material detection at the surface and pressure sensitivity at the bottom, with a porous middle layer sensitive to thermal changes.
In Review of Scientific Instruments, researchers from the University at Buffalo develop a tool for measuring the viscosity of lava that could increase our understanding of molten rock as well as better improve models of its movement, giving authorities crucial guidance for keeping people safe.
Plant hydraulics drive the biological process that moves fluids from roots to plant stems and leaves, creating streaming electric potential, or voltage, in the process.
As communities are flooded with pickleball courts to satiate the hunger for the snack-named game, HOAs and city councils face litigation by those whose lives are disrupted by pickleball’s din. The sport is uniquely noisy due to the hard paddles and balls, and the popping sound the game produces is sharp and persistent. Charles Leahy used his legal expertise and mechanical engineering experience to investigate how communities respond to the pickleball problem. Leahy will present his findings and recommendations for limiting pickleball noise at the 186th ASA Meeting.
Noise-canceling headphones automatically identify background sounds and cancel them out for much-needed peace and quiet. However, typical noise-canceling fails to distinguish between unwanted background sounds and crucial information, leaving headphone users unaware of their surroundings.
At the Toronto Pearson International Airport, airplane traffic dropped by 80% in the first few months of lockdown during the COVID-19 pandemic., and in early 2020, the NVH-SQ Research Group out of the University of Windsor surveyed residents living around the airport to gauge how their annoyance levels changed with the reduction in noise.
Sarcasm is notoriously tricky to convey through text, and the subtle changes in tone that convey sarcasm often confuse computer algorithms as well, limiting virtual assistants and content analysis tools.
