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

Insights into water flow and fish passage through dams offer options for meeting energy, environmental needs
Hydropower dams provide reliable renewable energy, but they also have a direct impact on the environment, especially fish. Adjusting the amount of water spilling over a dam can help fish successfully navigate dams. But spilling more water means less.....»»
Gene flow in giraffes and what it means for their conservation
Giraffes are a beautiful and powerful example of what adaptive evolution can achieve. However, in recent years, they have attained notoriety for a completely different reason: it has been suggested that instead of one giraffe species, there might be.....»»
Seismological study shows ancient lower mantle flow field under Philippine sea plate
Researchers from China and Japan have discovered distinct characteristics of Earth's lower mantle flow field. They investigated seismic anisotropy in the upper part of the lower mantle beneath the Philippine Sea Plate (PSP) and found that the ancient.....»»
A 3D view into chaos: Researchers visualize temperature-driven turbulence in liquid metal for the first time
Experiments with liquid metals could not only lead to exciting insights into geophysical and astrophysical flow phenomena, such as atmospheric disturbances at the rim of the sun or the flow in the Earth's outer core, but also foster industrial applic.....»»
Analysis establishes a framework for fairness in accounting, auditing
Nearly 40 years ago, the esteemed accounting professor Yuji Ijiri suggested that fairness is one of the most essential concepts in accounting and asked how to ensure a fair information flow system. In a new analysis, researchers examine whether it is.....»»
Harmful "forever chemicals" removed from water with new electrocatalysis method
Scientists from the University of Rochester have developed new electrochemical approaches to clean up pollution from "forever chemicals" found in clothing, food packaging, firefighting foams, and a wide array of other products. A new Journal of Catal.....»»
New Study Estimates as Much as $75 Billion in Global Victims’ Losses to Pig-Butchering Scam
“These are large criminal organized networks, and they’re operating largely unscathed,” said the lead author of the study, which tracked the flow of funds through crypto exchanges. Pig-butchering scammers have likely stolen mo.....»»
Study shows climate change disrupts seasonal flow of rivers
Climate change is disrupting the seasonal flow of rivers in the far northern latitudes of America, Russia and Europe and is posing a threat to water security and ecosystems, according to research published in Science......»»
