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.....»»
Into the belly of the rover: VIPER"s final science instrument installed
A team of engineers is preparing to integrate TRIDENT—short for The Regolith Ice Drill for Exploring New Terrain—into the belly of NASA's first robotic moon rover, VIPER (Volatiles Investigating Polar Exploration Rover)......»»

Researchers studying ocean transform faults, describe a previously unknown part of the geological carbon cycle
Studying a rock is like reading a book. The rock has a story to tell, says Frieder Klein, an associate scientist in the Marine Chemistry & Geochemistry Department at the Woods Hole Oceanographic Institution (WHOI)......»»
Scientists study the behaviors of chiral skyrmions in chiral flower-like obstacles
In nature, the collective motion of some birds and fish, such as flocks of starlings and shoals of sardines, respectively, can generate impressive dynamic phenomena. Their study constitutes active matter science, which has been a topic of great inter.....»»
Disadvantaged communities in Massachusetts twice as likely to have poor roads—and pay the cost in gas
A new study led by University of Massachusetts Amherst engineers paints a clear picture that people in disadvantaged communities in Massachusetts have poorer road quality and are more likely to need to use more fuel for their vehicles as a result......»»
Bizarre snake-like worm"s secrets revealed in CT scans
Amphisbaenians are strange creatures. Like worms with vertebrae, scales, a large central tooth and sometimes small forearms, these reptiles live underground, burrowing tunnels and preying on just about anything they encounter, not unlike a miniature.....»»
Countries Are Building Giant ‘Sand Motors’ to Protect Their Coasts From Erosion
As sea levels rise, engineers are using massive Dutch-inspired sand sculptures to protect shorefront settlements......»»
Researchers demonstrate multi-photon state transfer between remote superconducting nodes
Over the past few decades, quantum physicists and engineers have been trying to develop new, reliable quantum communication systems. These systems could ultimately serve as a testbed to evaluate and advance communication protocols......»»

Researcher examines proactive change-oriented behaviors by public service providers
Although change-oriented behaviors are critical to high-quality public service delivery, encouraging employees to embrace and pursue change in the public sector is difficult. Even with sufficient job autonomy—the principal antidote to resistance to.....»»
The social life of mouse immune systems
Hanging out a lot with the same crowd can make immune systems of individual animals similar, even if the crowd is not related. That's according to a recent paper published in Science Advances that teased out connections between social behaviors and i.....»»
Advanced measurements unravel nanoscale phenomena in tungsten diselenide
Semiconductor 2D materials are a few atoms thick, and some of them exhibit localized emission, where light is emitted from such a small part of the layer that only one photon at a time is produced. This localized emission has unique properties and is.....»»
Does naming a behavior encourage people to do it? A new study says yes
Researchers from Zeppelin University, University of Cologne, and UNSW Sydney have published a new study that explores marketing uses for "behavioral labeling," or giving behaviors specific names or tags to encourage people to adopt those behaviors......»»
Microfluidic environments alter microbe behaviors, opening potential for engineering their social evolution
Microbes are social beings. Much like humans, they communicate and cooperate with each other to solve problems bigger than themselves. In a microbial community, there will even be free riders and others that police them......»»
How food availability could catalyze cultural transmission in wild orangutans
The proverb "necessity is the mother of invention" has been used to describe the source from which our cultural evolution springs. After all, need in times of scarcity has forced humans to continually invent new technologies that have driven the rema.....»»
Researchers describe a novel species of jellyfish discovered in a remote location in Japan
A research team has published a description of a rare medusa found at a depth of 812 meters. The animal has been sighted only twice in a deep-sea volcanic structure called Sumisu Caldera, in the Ogasawara Islands. The gelatinous animal with a diamete.....»»
Ultra-sensitive lead detector could significantly improve water quality monitoring
Engineers at the University of California San Diego have developed an ultra-sensitive sensor made with graphene that can detect extraordinarily low concentrations of lead ions in water. The device achieves a record limit of detection of lead down to.....»»
