Most coffee connoisseurs are familiar with the gentle hum of their favorite café’s grinder while they wait in eager anticipation of that aromatic first sip. But behind this everyday scene lies a surprisingly tricky problem. […]
Engineers have designed robots that crawl, swim, fly and even slither like a snake, but no robot can hold a candle to a squirrel, which can parkour through a thicket of branches, leap across perilous […]
Researchers at the University of Turku, Finland, investigated how to use bio-based materials to produce effective UV protection films for solar cells. The study, published in ACS Applied Optical Materials, was the first to compare […]
New York’s JFK airport is an overlapping patchwork of open terminals, giant building sites and burgeoning infrastructure, wedged in by thousands of homes on one side and the ocean on the other.This post was originally […]
Using seawater, electricity and carbon dioxide (CO2), Northwestern University scientists have developed a new carbon-negative building material.This post was originally published on this site
It’s difficult to build devices that replicate the fluid, precise motion of humans, but that might change if we could pull a few (literal) strings. At least, that’s the idea behind “cable-driven” mechanisms in which […]
Much of our waste is far too valuable to simply be incinerated. If it is recycled in a carefully controlled way, not only can thermal energy be generated, but the resulting gas can also be […]
Over the past two decades, Haiti has endured the devastation of two catastrophic earthquakes—first in 2010 and again in 2021. Each disaster left behind widespread destruction: buildings reduced to rubble, entire communities displaced and an […]
A major challenge in self-powered wearable sensors for health care monitoring is distinguishing different signals when they occur at the same time. Researchers from Penn State and China’s Hebei University of Technology have addressed this […]
Engineering researchers at Lawrence Livermore National Laboratory (LLNL) have achieved breakthroughs in multi-material additive manufacturing (3D printing) through the power of capillary action. The LLNL team printed lattice structures with a series of custom-designed unit […]
