Cells selectively absorb short nanotubes

DNA-wrapped single-walled carbon nanotubes (SWCNTs) shorter than about 200 nanometers readily enter into human lung cells and so may pose an increased risk to health, according to scientists at the National Institute of Standards ...

Traces of nanobubbles determine nano-boiling

Using a microscope and some extreme “snapshot” photography with shutter speeds only a few nanoseconds long, researchers from the National Institute of Standards and Technology and Cornell University have uncovered the ...

Titanium dioxide -- It slices, it dices ...

Chemists from the National Institute of Standards and Technology and Arizona State University have proposed an elegantly simple technique for cleaving proteins into convenient pieces for analysis. The prototype sample preparation ...

Abrupt climate change more common than believed

It came on quickly and then lasted nearly two decades, eventually killing more than one million people and affecting 50 million more. All of this makes the Sahel drought, which first struck West Africa in the late 1960s, ...

Congress Commends UM-Led Math Team's Breakthrough E8 Calculation

A major mathematical breakthrough by a team of 18 scientists, led by University of Maryland mathematician Jeffrey Adams, has been commended by Congress, one week after the work made international headlines when it was announced ...

Scientists shed new light on cold fusion

U.S. scientists say the concept of cold fusion, a controversial concept once hailed as a scientific breakthrough, may be ready for rebirth.
