Understanding patterns of seafloor biomass

Analysis of a comprehensive database has revealed strong links between biological productivity in the surface oceans and patterns of biomass and abundance at the seafloor, helping to explain large regional differences. The research was conducted...

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...

Engineers grow nanolasers on silicon, pave way for on-chip photonics

Berkeley -- Engineers at the University of California, Berkeley, have found a way to grow nanolasers directly onto a silicon surface, an achievement that could lead to a new class of faster, more efficient microprocessors, as well as to powerful ...

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...

First report on fate of underwater dispersants in Deepwater Horizon oil...

Scientists are reporting that key chemical components of the 770,000 gallons of oil dispersants applied below the ocean surface in the Deepwater Horizon spill did mix with oil and gas spewing out of the damaged wellhead and remained in the deep ...

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...
