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.....»»
Scientists marry MRI, ultrasound, and optoacoustics for improved medical exams
Physicians and researchers rely on biomedical imaging to examine the structure and function of living tissue. This enables disease diagnostics and experiments that reveal the mechanisms behind pathologies and ways to treat them. The most popular tech.....»»
Evaluating the shear viscosity of different water models
Water is one of the most abundant substances on Earth and partakes in countless biological, chemical, and ecological processes. Thus, understanding its behavior and properties is essential in a wide variety of scientific and applied fields. To do so,.....»»
Unveiling the science of ultrasound-driven microbubble desorption
Injecting drugs into the bloodstream can often harm healthy tissues as well. Drug delivery systems (DDSs) are an innovative solution designed to target specific cells and minimize such side effects. One strategy for drug delivery that has steadily ga.....»»
smdh: New Unicode 15.1 emoji include nodding/shaking heads, “edible mushroom”
New emoji are technically all modifications of existing designs. Enlarge / Examples of new and modified emoji in Unicode 15.1. (credit: Emojipedia) The Unicode Consortium has finalized version 15.1 of the Unicode standa.....»»
New methodology combines earthquake ground shaking and ground failure for forecasting gas pipeline damage
After an earthquake strikes in an area with a buried gas pipeline network, it can be critical to identify where potential damage to the pipeline might have occurred—especially since these networks can cover hundreds of kilometers and may sometimes.....»»
Ultrasound can briefly induce a hibernation-like state in animals
Science fiction has long described sophisticated technology that can temporarily put humans into a suspended state, permitting characters to awaken far into the future, often after extended journeys through space. In reality, the basis for suspended.....»»
Self-driving vehicles may reshape transportation, whether the cities that host them like it or not
San Francisco serves as a case study for the rollout of robotaxis, especially as Cruise and Waymo get ready to ramp up their driverless services. Others are taking close note of the friction and complications there......»»
Scientists theorize a hidden phase transition between liquid and a solid
Anything made out of plastic or glass is known as an amorphous material. Unlike many materials that freeze into crystalline solids, the atoms and molecules in amorphous materials never stack together to form crystals when cooled. In fact, although we.....»»
Disney announces price hike for Disney+ and Hulu, crackdown on password sharing
Disney is shaking up its portfolio of streaming services starting next month. The company announced today that it would increase the pricing for ad-free Disney+ and Hulu while also saying that it is “actively exploring” ways to crack down on pass.....»»
This Heat Is Shaking the Very Foundation of the Ocean Food Web
Yes, save the corals. But warming seas also imperil innumerable plankton, which power the oceanic ecosystem......»»
Ultrasound-based microfluidic manipulation platform for airborne droplets
As science races toward automation and quick experiments, it is sometimes required to concurrently handle small amounts of liquids (droplets), from picoliters to microliters. Moreover, droplet jumping is required when transporting droplets to distant.....»»
The Atlantic is frying, but so far hurricanes are dying. What’s going on?
Can wind shear and sinking air hold historically high sea temperatures at bay? Enlarge / Don briefly reached hurricane status in July 2023. (credit: NOAA) As July came to a close, the Atlantic Ocean was absolutely sizzl.....»»
How the Apple-Goldman Sachs relationship became an unhappy marriage
Apple's relationship with Goldman Sachs led to the creation of the wildly successful Apple Card, but post-launch friction and a change in priorities has crashed the relationship into the rocks.Apple and Goldman Sachs have an extensive history togethe.....»»
Rosé renaissance: Spanish study uncorks ultrasound for superior wine quality
Since the International Organization of Vine and Wine (OIV) approved the use of ultrasound to promote the extraction of grape compounds back in 2019, its application for obtaining superior red wines has been studied extensively......»»
Laser pulse creates exotic order in quantum material
Water flows, ice is rigid—this clear difference between the liquid and solid state of substances is part of our everyday experience. It follows from the very regular arrangement of atoms and molecules in crystalline solids, which is lost when they.....»»
Physicists rediscover a discarded theory to solve a mystery of how glass damping sound
For about half a century, physicists have puzzled over vibrations in glass at low temperatures. The reason: Glass carries sound waves and vibrations differently than other solids—it "vibrates differently." But why? And how can the propagation of so.....»»
Unraveling the super-complex structure of supercooled liquids
When cooled to their freezing point, most liquids become solids or crystallize. In other words, the molecules arrange themselves in a perfectly ordered fashion, which physicists call a crystal. Supercooled liquids are different; they do not form such.....»»
New criteria to determine whether shear bands are beneficial or harmful to crystalline materials
Shear band formation is not typically a good sign in a material—the bands often appear before a material fractures or fails. But materials science and engineering researchers at the University of Wisconsin–Madison have found that shear bands aren.....»»
Seismological analysis of the two earthquakes that devastated southern Turkey
On February 6, 2023, two major earthquakes with moment magnitudes of 7.9 and 7.6 occurred in southeastern Türkiye, near the Syria-Türkiye border. The two major earthquakes were close in time and space and can be considered twins. The shaking from t.....»»
Novel spectroscopic technique for exploring relaxor–ferroelectric materials
The exploitation of polarization or charge separation in ferroelectric materials has led to remarkable advances in various fields, such as the development of new ultrasound diagnostic devices. Prominently, these ferroelectric materials have led to pi.....»»
