Aging societies more vulnerable to collapse, suggests analysis
Societies and political structures, like the humans they serve, appear to become more fragile as they age, according to an analysis of hundreds of pre-modern societies. A new study, which holds implications for the modern world, provides the first qu.....»»
New understanding of "oobleck-like" fluids contributes to smart material design
If you mix cornstarch and water in the right proportions, you get something that seems not-quite-liquid but also not-quite-solid. Oobleck flows and settles like a liquid when untouched but stiffens when you try to pick it up or stir it with a spoon......»»
When physics meets biology: Prion protein orchestrates liquid–liquid phase separation with copper
In a study published in Science Advances, researchers from the Federal University of Rio de Janeiro (UFRJ) and the German Center for Neurodegenerative Diseases (DZNE-Berlin) shed light on the intricate dance between the prion protein and copper ions.....»»
Researchers develop a new approach to polarization-independent LC phase modulation
Liquid-crystal (LC) phase modulators are widely used in optical systems because of their advantages of low power consumption, lightweight, flexible bandwidth adjustment, and non-mechanical movements. However, most LC phase modulators are polarization.....»»
Coping with uncertainty in customer demand: How mathematics can improve logistics processes
How do you distribute drinking water fairly across an area recently hit by a natural disaster? Or how can you make sure you have enough bottles of water, granola bars and fruit in your delivery van to refill all the vending machines at a school when.....»»
Researchers describe the journey of thermal antibubbles in a hot bath
Bubbles are thin liquid shells surrounded by air. Although less well known, there are also antibubbles, which are the opposite of bubbles, i.e., a thin envelope of vapor surrounded by liquid. In a new study, we show that it is possible to create anti.....»»
Three-pronged approach discerns qualities of quantum spin liquids
In 1973, physicist Phil Anderson hypothesized that the quantum spin liquid, or QSL, state existed on some triangular lattices, but he lacked the tools to delve deeper. Fifty years later, a team led by researchers associated with the Quantum Science C.....»»
Study resolves puzzles in gravitational collapse of gravitational waves
Black holes are regions in space where the gravitational pull is so strong that nothing can escape them, not even light. These fascinating regions have been the focus of countless studies, yet some of the physics underlying their formation is not yet.....»»
Researchers: Collapse of West Antarctic ice sheet is still preventable—if we act fast to keep future warming in check
Projecting when and how fast the West Antarctic Ice Sheet will lose mass due to current and future global ocean warming—and the likely impact on sea level rise and coastal communities—is a priority for climate science......»»
The governance gap: Balancing innovation and ecological responsibility in a world at risk
"The world isn't doing terribly well in averting global ecological collapse," says Dr. Florian Rabitz, a chief researcher at Kaunas University of Technology (KTU), Lithuania, the author of a new monograph, "Transformative Novel Technologies and Globa.....»»
Liquid metals shake up century-old chemical engineering processes
Liquid metals could be the long-awaited solution to "greening" the chemical industry, according to researchers who tested a new technique they hope can replace energy-intensive chemical engineering processes harking back to the early 20th century......»»
Experts predict "catastrophic ecosystem collapse" of UK forests within the next 50 years if no action is taken
A team of experts from across Europe has produced a list of 15 over-looked and emerging issues that are likely to have a significant impact on UK forests over the next 50 years......»»
Matic is a $1,795 robot vacuum for people concerned about privacy
Relying on local processing, Matic can see your home and suck up liquid spills. Matic should be able to suck up that spill. [credit:.....»»
Macs can now detect water in USB-C ports and spot warranty fraud
To cut down on warranty claims, Apple has added a background feature with macOS Sonoma that runs liquid detection analysis on every USB-C port on a Mac.USB-C ports (plus left, MagSafe, and right, a headphone jack) on a 14-inch MacBook ProBack in 2010.....»»
A review of liquid crystal spatial light modulators devices and applications
Technology to control and harness light has existed for centuries, often as static solutions that must be custom-designed. It is only in the past couple of decades that the digital era of micro-electronics and computing has seen fast rewritable techn.....»»
UN report warns of catastrophic climate tipping points: California is nearing several
Humanity is on course to transgress multiple global "tipping points" that could lead to irreversible instability or the complete collapse of ecological and institutional systems, a United Nations report has warned......»»
New study finds Mars"s liquid iron core is smaller and denser than previously thought
For four years, NASA's InSight lander recorded tremors on Mars with its seismometer. Researchers at ETH Zurich collected and analyzed the data transmitted to Earth to determine the planet's internal structure. "Although the mission ended in December.....»»
A new formula to calculate the strength of thin conical structures
Conical structures can have advantageous applications in a variety of fields, ranging from robotics to civil engineering. Studies have found that conical shells made of liquid crystal elastomer films can be effective lifters; devices that can generat.....»»
Biases found in coral reef research
Coral reefs support approximately 25% of marine species, and are essential to coastal economies, such as the fishing and tourism industries, to name a few. But coral reefs worldwide are at risk due to climate change and are on the brink of collapse......»»
