Cross-sectional area variation as a key factor for pressure wave attenuation in hilarious flows: a theoretical analysis.
Credit: International Journal by Multiphase Flow (2025). doi:10.1016/j.ijmultiphaseflow.2025.105138 Pressure waves propagating through the liquid containing bubbles in the tube experience considerable decay. Researchers at Tsukuba University have derived an equation explaining this phenomenon, showing that variations in the tube cross-sectional area contribute to wave attenuation, beyond the viscosity and compressibility of the liquid. Their analysis reveals that the rate of…

Monkeys are the best yoderers in the world, find “voice break” analysis
Black and gold Haurasal (Alouatta Caraya). Credit: Dr. Jacob Dunn, Anglia Ruskin University New research has found that the world’s most incredible yodelers are not from Austria or Switzerland, but from the tropical rainforests of Latin America. Published in the Journal Philosophical Transactions of the Royal Society B and led by experts from Anglia Ruskin University (ARU) and the University…

Real-time analysis reveals a much higher proportion of hazardous substances in particulate matter than expected
A significant portion of the ROS and OP activity of aerosol particles fades prior to offline analysis. Credit: Science Advances (2025). doi:10.1126/sciadv.adp8100 For years, people breathing contaminated air are at a higher risk of developing many illnesses. This is thought to be due to the highly reactive components of particulate matter that affect biological processes within the body. However, researchers…

“Democratic Chemistry Analysis”: Using machine learning and robotics to identify chemical compositions from images
Microscopic images of potassium nitrate. Credit: Oliver Steinbock A chemist at Florida State University has created a machine learning tool that can identify the chemical composition of a dry salt solution from an image with 99% accuracy. By preparing thousands of samples and artificial intelligence using robotics to analyze the data, we created a simple and inexpensive tool that expands…

Considering the Mars water discussion: Analysis challenges previous findings
Credit: Pixabay/CC0 Public Domain Over three billion years ago, Mars had intermittently held liquid water on its surface. However, after the planet lost much of its atmosphere, surface waters could no longer last. The fate of Mars’ waters is buried like ice, trapped in deep aquifers, incorporated into minerals and dissipated into space. Last week, in a letter to the…

Utilizing gravity to create low-cost microfluidic devices for rapid cell analysis
Slug flow driven microfluidic chip. Credit: Denis Soward/Rice University A team of researchers at George R. Brown School of Engineering and Computing at Rice University has developed an innovative, low-cost AI-enabled device for creating flow cytometry. The prototypes identify and count cells from unpurified blood samples with similar accuracy to more expensive and bulky traditional flow cytometers, providing results within…

The analysis reveals global patterns of trait matching in bird and plant networks
A: Chestnut-colored Oriol (Oriolus trailii) (Lindera sp.) eating spicewood fruit; B: Flower pecker (Dicaeum cruentatum) supported by scar-colored eating fruit of drizzling (Viscum sp.). Credit: Midiexiang, Red Vision In 1862, Charles Darwin predicted the presence of moth with his long tongue, based on the nectar spur of comet orchids. This was confirmed in the long-carved Hawkmoth discovery in 1903, showing…

Analysis finds defects in the “Protura sister” hypothesis: reassessment of early hexapole lines
Embryology and morphology cannot establish the “Protura sister” hypothesis of the early evolution of hexapoders recently proposed by phylogenies. Credit: Makiko Fukui Early lineages of hexagons (widely defined insects) have been debated for a long time. Researchers and collaborators from Tsukuba University have critically investigated the newly proposed phylogenetic hypothesis of the “Protura sisters.” This analysis revealed the underlying flaws…
