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.....»»

How fast are Arctic glaciers melting? Engineers explored the north with a robot and cameras to find out
Equipped with snow jackets, gloves and luggage containing a host of cameras and sensors, professor Hanumant Singh and a team of Northeastern robotics researchers recently traveled to the Arctic with a noble goal to help address the climate crisis......»»
Video: Student engineers develop early warning system for blue-green algae
With temperatures rising due to global warming, blue-green algae blooms have become increasingly common on Alberta lakes. Early detection is crucial because the algae produce toxins that can be harmful to humans and animals......»»
Apple modem chip project failed because it’s harder than CPUs, engineers tell WSJ
Attempts to design an Apple modem chip to replace the Qualcomm radio chips used in iPhones have been ongoing since at least 2018 – but some five years later have been deemed a failure by engineers who worked on the project. Even by last year, th.....»»
Workers uncover eight mummies and pre-Inca objects while expanding the gas network in Peru
Some archaeologists describe Peru's capital as an onion with many layers of history, others consider it a box of surprises. That's what some gas line workers got when their digging uncovered eight pre-Inca funeral bales......»»
From forming embryo to cancer metastasis: The significance of collective cell movement
Against all expectations, the most common tissue in our bodies behaves differently at different length scales. That's what physicist Luca Giomi discovered in his research into the flow of cells. "Our findings are even more interesting than we hoped f.....»»
New study disproves Leonardo da Vinci"s "rule of trees"
A "rule of trees" developed by Leonardo da Vinci to describe how to draw trees has been largely adopted by science when modeling trees and how they function......»»
