It converts from sheets to tubes and back in a controllable fashion — ScienceDaily

Chemists have developed a nanomaterial that they can trigger to shape shift — from flat sheets to tubes and back to sheets again — in a controllable fashion. The Journal of the American Chemical Society published a description of the nanomaterial, which was developed at Emory University and holds potential for a range of biomedical […]

Ancestral Puebloans melted ice in lava tubes to survive droughts

During a parched summer almost 2,000 years ago, people living in what is now western New Mexico crawled into the cold, dark belly of a volcanically formed cave to melt the frozen water at its heart. The ice preserved in these naturally cool formations might have helped Ancestral Puebloans in the region persevere through five […]

Geoscientists discover Ancestral Puebloans survived from ice melt in New Mexico lava tubes

But surviving in what Spanish […]

In specially coated tubes, the more viscous a liquid is, the faster it flows

Drops of honey on a hydrophobic surface. Credit: Aalto University It’s widely known that thick, viscous liquids—like honey—flow more slowly than low-viscosity liquids, like water. Researchers were surprised to find this behavior flipped on its head when the liquids flow through chemically coated capillaries. In fact, through these specially coated tubes, liquids a thousand times […]
