Not just for raincoats

Researchers from Northwestern University and the Massachusetts Institute of Technology (MIT) have studied individual water droplets and discovered a miniature version of the “water hammer,” an effect that produces the familiar radiator pipe clanging…

New discoveries improve climate models

New discoveries on how underwater ridges impact the ocean’s circulation system will help improve climate projections.
An underwater ridge can trap the flow of cold, dense water at the bottom of the ocean. Without the ridge, deepwater can flow free…

GRIN plasmonics

They said it could be done and now they’ve done it. What’s more, they did it with a GRIN. A team of researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, Berke…

Researchers discover how to tame hammering droplets

CAMBRIDGE, Mass. — A water hammer can occur when a valve is suddenly opened or closed in a pipe carrying water or steam, causing a pressure wave to travel down the pipe with enough force that it can sometimes cause the pipes to burst. Now, new rese…

MicroRNA suppresses prostate cancer stem cells and metastasis

HOUSTON — A small slice of RNA inhibits prostate cancer metastasis by suppressing a surface protein commonly found on prostate cancer stem cells. A research team led by scientists at The University of Texas MD Anderson Cancer Center reported …

A pesky bacterial slime reveals its survival secrets

Cambridge, Mass., January 7, 2011 — By rethinking what happens on the surface of things, engineers at Harvard University have discovered that Bacillus subtilis biofilm colonies exhibit an unmatched ability to repel a wide range of liquids — and…

Longstanding mystery of Sun’s hot outer atmosphere solved

One of the most enduring mysteries in solar physics is why the Sun’s outer atmosphere, or corona, is millions of degrees hotter than its surface.
Now scientists believe they have discovered a major source of hot gas that replenishes the corona…

Warning lights mark shellfish that aren’t safe to eat

Red tides and similar blooms can render some seafood unsafe to eat, though it can be difficult to tell whether a particular batch harbors toxins that cause food poisoning.
A new kind of marker developed by chemists at the University of California,…
