Shear ultrasound shaking found to lower friction between solids
When high-frequency shaking occurs at an interface between two solids, recent experiments have revealed that the frictional forces between the objects can be weakened. Through a simple new experiment detailed in The European Physical Journal E, Julie.....»»
Study identifies high-performance alternative to conventional ferroelectrics

Business-focused anti-poverty initiatives can have unintended consequences
A new study of entrepreneurial small businesses created to address poverty in rural Africa found that the introduction of the entrepreneurial model led to unexpected social shifts that made the small business operators a source of friction and social.....»»
Do earthquake hazard maps predict higher shaking than actually occurred? Research finds discrepancy
A new study by Northwestern University researchers and coworkers explains a puzzling problem with maps of future earthquake shaking used to design earthquake-resistant buildings. The research was published May 1 in the journal Science Advances in a p.....»»
Baby orangutan born at Tampa"s Busch Gardens via C-section is a rare feat
Luna loved the ultrasound game. The 26-year-old orangutan at Busch Gardens would come up to the mesh screening that separates the primates from the humans that care for them and happily present her belly......»»
Amphibians use scream inaudible to humans for self-defense against predators, study suggests
A study reported in the journal acta ethologica has recorded the use of ultrasound by amphibians for the first time in South America. It also describes the first documented case of the use of ultrasound for defense against predators, in a distress ca.....»»
Physics of complex fluids: Ring polymers show unexpected motion patterns under shear
The shearing of fluids—meaning the sliding of fluid layers over each other under shear forces—is an important concept in nature and in rheology, the science that studies the flow behavior of matter, including liquids and soft solids. Shear forces.....»»
Distant "space snowman" unlocks mystery of how some dormant deep space objects become "ice bombs"
A new study is shaking up what scientists thought they knew about distant objects in the far reaches of the solar system, starting with an object called the space snowman......»»
"Shear sound waves" provide the magic for linking ultrasound and magnetic waves
A team led by researchers from the RIKEN Center for Emergent Matter Science in Japan has succeeded in creating a strong coupling between two forms of waves—magnons and phonons—in a thin film. Importantly, they achieved this at room temperature, o.....»»
Researchers reveal new method for calculating mechanical properties of solids using machine learning
A research team from Skoltech introduced a new method that takes advantage of machine learning for studying the properties of polycrystals, composites, and multiphase systems. It attained high accuracy, nearly as good as that of quantum-mechanical me.....»»
MagSafe Monday: ESR for Qi2 15W MagSafe car mount delivers fast charging on the go
Oddly enough, wireless charging is one of my top use cases for MagSafe. Some of my earliest MagSafe accessories have been wireless chargers in the car. I don’t have long commutes every day, so I am frequently in and out of the car. The friction of.....»»
Hubble tracks Jupiter"s stormy weather
The largest and nearest of the giant outer planets, Jupiter's colorful clouds present an ever-changing kaleidoscope of shapes and colors. This is a planet where there is always stormy weather: cyclones, anticyclones, wind shear, and the largest storm.....»»
