Engineers describe how fluid suspensions exhibit different behaviors at different scales
Honey is already a thick liquid, but let it begin to crystalize and it can become downright clumpy. The sugar crystals in suspension seem to increase its viscosity. This phenomenon occurs throughout the natural and constructed world: From mudflows to.....»»
Researchers discover new way to purify liquid argon for neutrino experiments
Construction workers have finished the excavation of the huge caverns that will house the international Deep Underground Neutrino Experiment. While engineers and technicians are preparing for the installation of the gigantic neutrino detectors into t.....»»
How color shapes which animals we fear—and which we protect
Around the world, animals that exhibit rare color morphisms—including lighter-colored variants with albinism or leucism and dark-colored variants with melanism—are often the subject of both veneration and fear in humans......»»
An affordable tracking microscope to democratize microorganism research
Studying the complex motility patterns of cells and microorganisms is key to understanding their behaviors and biomechanics. However, many conventional microscopes are constrained by fixed lenses and the lack of ability to track organisms over extend.....»»
A new approach to fine-tuning quantum materials
Quantum materials—those with electronic properties that are governed by the principles of quantum mechanics, such as correlation and entanglement—can exhibit exotic behaviors under certain conditions, such as the ability to transmit electricity w.....»»
Saturday Citations: A rare misstep for Boeing; mouse jocks and calorie restriction; human brains in sync
This week's headlines include the extended sleepover for astronauts in the SpaceX Crew Dragon capsule, insight into our imitative behaviors, and the Olympic form of mice......»»
Model suggests spewing metal nanorods into Mars" atmosphere could warm the planet by 30 K
A small team of engineers and geophysicists from Northwestern University, the University of Chicago, and the University of Central Florida has found, via modeling, that creating millions of metal nanorods from material on the Martian surface and then.....»»
How Heat Index, Dew Point and Wet-Bulb Temperature Describe Summer Weather
When heat hits, we talk about the heat index, the dew point and heat risk. But what do all these measures mean?.....»»
Disaster plant pathology: Solutions to combat agricultural threats from disasters
An often-overlooked component of natural and human-driven disasters is their potential to affect plant health and thus food security at domestic and international scales. Most disasters have indirect effects on plant health through factors such as di.....»»
Engineers develop general, high-speed technology to model, understand catalytic reactions
Researchers have been studying the industrial production of ammonia for a century. But they've struggled to find ways to improve the low-yield, low-efficiency process......»»
"Current" events: Scientists devise a new way to measure river flows
A team of scientists and engineers at NASA and the U.S. Geological Survey (USGS) has collaborated to see if a small piloted drone, equipped with a specialized payload, could help create detailed maps of how fast water is flowing. Rivers supply fresh.....»»
Cygnus spacecraft suffers issue on the way to the space station
NASA had an issue with the Cygnus spaceship shortly after it launched for the ISS on Sunday, but engineers are still aiming to achieve the planned docking time......»»
More microbes found that break down the carbon-fluorine bonds found in some unsaturated PFAS
A team of chemical and environmental engineers at the University of California Riverside, working with colleagues from the University of California Los Angeles, has found a class of microbes that consume PFAS in the environment and sever some of the.....»»
Handling with care: PTSD in horses
Equine companionship is built upon a foundation of trust and care. Yet, maintaining a horse's trust can be challenging, especially when a past event has left the animal with behaviors mirroring what's diagnosed as post-traumatic stress disorder (PTSD.....»»
Health-threat "forever chemicals" removed from water with 3D-printed ceramic ink
Engineers have invented a new way to remove health-harming 'forever chemicals' from water—using 3D printing......»»
Predicting soil liquefaction risk using artificial intelligence
Soil liquefaction that results in infrastructure damage has long been a point of contention for urban planners and engineers. Accurately predicting the soil liquefaction risk of a region could help overcome this challenge......»»
Sustainable and reversible 3D printing method uses minimal ingredients and steps
A new 3D printing method developed by engineers at the University of California San Diego is so simple that it uses a polymer ink and salt water solution to create solid structures. The work, published in Nature Communications, has the potential to m.....»»
Researchers explore cancer susceptibility in birds
In one of the largest studies of cancer susceptibility across bird species, researchers at Arizona State University describe an intriguing relationship between reproductive rates and cancer susceptibility......»»
Quantum information theorists shed light on entanglement, one of the spooky mysteries of quantum mechanics
The year 2025 marks the 100th anniversary of the birth of quantum mechanics. In the century since the field's inception, scientists and engineers have used quantum mechanics to create technologies such as lasers, MRI scanners and computer chips......»»
