To 3D print with fiber-infused liquids, we need to understand how these drops form, break-up, and splash. That’s the subject of this research poster, which shows drops of a fiber Keep reading

Liquid Metal Printing
Engineers have developed a new 3D-printing technique that uses molten aluminum to quickly manufacture large-scale parts. This Liquid Metal Printing method deposits the metal into a bed of tiny glass Keep reading
Water Reduces Coffee’s Charge
Grinding coffee beans builds up electrical charge as the beans fracture into smaller and smaller pieces. The polarity of the charge depends on the bean’s moisture content; lighter roasts tend Keep reading
“Coat or Collapse?”
Imagine a layer of particles sitting at the interface between oil and water. Known as a granular raft, these particles can interact in interesting ways with other objects. Here, researchers Keep reading
Frictional Fingers
Air pushes into a thin gap filled with water and granular particles in the labyrinth-like image above. The encroaching air pushes grains like a bulldozer’s blade, building up a compacted Keep reading
Granular Gaps
Push air into a gap filled with a viscous fluid, and you’ll get the branching, dendritic pattern of a Saffman-Taylor instability. Here, researchers use a similar set-up: injection into a Keep reading
“Emerald Roots”
As charged particles from the solar wind bombard the upper atmosphere, a glowing plasma forms and dances in the sky. The green light of the plasma reflects off moistened sand, Keep reading
Shifting Sands
Qinghai Lake sits in western China, where a warmer and wetter climate has been raising the lake’s water level in recent years. These two satellite images, from 2010 and 2022, Keep reading
Swimming Through Mud
At the bottom of ponds, nematodes and other creatures swim in a world of mud. They squirm their way through a sediment of dirt particles suspended in water. Mud, of Keep reading
Snake Tracks
Moving across sand is quite challenging for bipedal creatures like us, but other animals have their ways. Photographer Paul Lennart Schmid caught this snake on the move, with impressions of Keep reading
