Too many vehicles, slow reactions and reckless merging: New math model explains how traffic and bacteria move
What do the flow of cars on a highway and the movement of bacteria towards a food source have in common? In both cases, annoying traffic jams can form. Especially for cars, we might want to understand how to avoid them, but perhaps we've never though.....»»
Standardized power management could extend EV battery range
The automotive industry is being pushed to establish a standard to manage the power flow to electronic control units that govern different parts of the vehicle depending on the context......»»
Human activities have an intense impact on Earth"s deep subsurface fluid flow
The impact of human activities—such as greenhouse gas emissions and deforestation—on Earth's surface have been well-studied. Now, hydrology researchers from the University of Arizona have investigated how humans impact Earth's deep subsurface, a.....»»
A new electrochemical approach could reduce ocean acidity and remove carbon in the process
In the effort to combat the catastrophic impacts of global warming, we must accelerate carbon emissions reduction efforts and rapidly scale strategies to remove carbon dioxide (CO2) from the atmosphere and the oceans. The technologies for reducing ou.....»»
Record electron temperatures for a small-scale, sheared-flow-stabilized Z-pinch fusion device achieved
In the nine decades since humans first produced fusion reactions, only a few fusion technologies have demonstrated the ability to make a thermal fusion plasma with electron temperatures hotter than 10 million degrees Celsius, roughly the temperature.....»»
RNA"s hidden potential: New study unveils its role in early life and future bioengineering
The beginning of life on Earth and its evolution over billions of years continue to intrigue researchers worldwide. The central dogma or the directional flow of genetic information from a deoxyribose nucleic acid (DNA) template to a ribose nucleic ac.....»»
Researchers create nanomembrane to increase reaction rate in chemical production
Flow-through reactors packed with enzymes can produce certain chemicals in a gentle and careful way. However, their performance has so far been limited. A research team from the Helmholtz-Zentrum Hereon and RWTH Aachen University has now been able to.....»»
Examining the blowtorch effect of satellite reentry through video
A reaction wheel—one of the heaviest parts of a space mission, its changing rotation used to shift a satellite's orientation—seen in a plasma wind tunnel belonging to the High Enthalpy Flow Diagnostics Group (HEFDiG) at the University of Stuttgar.....»»
Why this unassuming tablet is my favorite laptop of the year so far
The Asus ROG Flow Z13 would be impressive as a 14-inch laptop. As a 13-inch detachable tablet, it's incredibly fast, well-made, and easy to recommend......»»
The next-generation triggers for CERN detectors
The experiments at the Large Hadron Collider (LHC) require high-performance event-selection systems—known as "triggers" in particle physics—to filter the flow of data to manageable levels. The triggers pick events with distinguishing characterist.....»»
Tiny cracks in rocks may have concentrated chemicals needed for life
The gentle flow of warm fluids could have given pre-life chemistry a boost. Enlarge / Active geology could have helped purify key chemicals needed for life. (credit: Christof B. Mast) In some ways, the origin of life is.....»»
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.....»»
New electrochemical technology could de-acidify the oceans—and even remove carbon dioxide in the process
In the effort to combat the catastrophic impacts of global warming, we must accelerate carbon emissions reduction efforts and rapidly scale strategies to remove carbon dioxide (CO2) from the atmosphere and the oceans. The technologies for reducing ou.....»»
Largest ice shelf in Antarctica lurches forward once or twice each day
In Antarctica, heavy glaciers are always on the move. Conveyor belts of ice, known as ice streams, are the corridors of faster flow that carry most of the vast glaciers' ice and sediment debris out toward the ocean......»»
A catalyst for converting carbon dioxide, the main cause of global warming, into ethylene using vitamin C
A joint research team has developed a new electrochemical catalyst that promotes the conversion from carbon dioxide (CO2) to ethylene (C2H4)......»»
Severe hurricanes boost influx of juveniles and gene flow in a coral reef sponge
Named for its ropy-looking long branches, Aplysina cauliformis, a coral reef sponge, provides a critical 3D habitat for marine organisms and helps to stabilize the foundation of coral reefs. However, these upright-branching sponges are highly suscept.....»»
Enhancing safety in green adipic acid synthesis: The role of EDTA stabilizer and microchannel flow technology
Adipic acid, a fundamental component in the manufacture of chemical fibers, nylon 66, engineering plastics, and various pharmaceutical, food, and chemical products, is commonly synthesized through a green process involving the oxidation of cyclohexen.....»»
Regula 4205D updates help border control authorities fight identity document fraud
The International Organization for Migration reports that the migrant flow has been steadily rising, with the numbers swelling from 153 million in 1995 to 281 million in 2022. Concurrently, the quality of counterfeit documents keeps advancing. Under.....»»
Insights into water flow and fish passage through dams offer options for meeting energy, environmental needs
