It's been used to dye the Chicago River green on St. Patrick's Day. It's been used to find latent blood stains at crime scenes. And now researchers at Northwestern University have used it to examine the thinnest material in the world. The useful tool is the dye fluorescein, and Jiaxing Huang, assistant professor of materials science and engineering at the McCormick School of Engineering and Applied Science, and his research group have used the dye to create a new imaging technique to view...

PITTSBURGH, Dec. 15 /PRNewswire/ -- Ever wonder what something looks like up close and personal? ASPEX wants your samples! ASPEX, makers of the Personal Scanning Electron Microscope (PSEM), kicked off its "Send Us Your Sample" campaign, encouraging people to send in samples to be scanned by one of their PSEMs. The PSEM has a scan range of 100nm to 5mm and an imaging resolution of 25nm, capable of bringing the smallest samples into focus. In addition, ASPEX will not only scan your sample,...

Sharper vision for new insights into biological questions, including DNA repair An ultra-high-resolution imaging technique using X-ray diffraction is a step closer to fulfilling its promise as a window on nanometer-scale structures in biological samples. In the Proceedings of the National Academy of Sciences, researchers report progress in applying an approach to "lensless" X-ray microscopy that they introduced one year ago. They have produced the first images, using this technique, of...

Excavations carried out at the 14th Century city wall of Granada have unearthed a brick kiln located next to stratified layers of bones and ashes. According to researchers from the University of Granada (UGR), this in situ evidence suggests that this kiln was used to manufacture a coating for the wall, which incorporated powder made from burnt bones. "The bricks from the kiln that was discovered showed evidence of melting (blackened surfaces and small bubbles), which indicates that...

By Chakraborty, A Ray, R K; Sangal, S An attempt has been made to characterize the microstructural and textural aspects of the substrate and the coated layer on industrially produced galvannealed interstitial-free (IF) steel. A number of experimental techniques were used for this purpose. The major part of the coating was found to be made up of the delta layer, favorable for good formability. The texture of the substrate steel contained a sharp gamma component, which imparts high deep...

Just as test pilots push planes to explore their limits, researchers at the National Institute of Standards and Technology (NIST) are probing the newest microscope technology to further improve measurement accuracy at the nanoscale. Better nanoscale measurements are critical for setting standards and improving production in the semiconductor and nanomanufacturing industries. This new microscope technology uses helium ions to generate the signal used to image extremely small objects, a...

There are few things more irritating than a fly buzzing around the house. South Africans have an unconventional solution to the problem. They hang up a bunch of Roridula gorgonias leaves. Attracted to the shiny adhesive droplets on the leaf's hairs, the hapless pest is soon trapped by the natural flypaper. However, this is not the end of the story. Each R. gorgonias plant is home to a population of Pameridea roridulae (mirid bugs), which dine on the trapped insects. Yet the mirid bugs...

Word of the Day
  • Like a worm in form or movement; vermiform; tortuous or sinuous; also, writhing or wriggling.
  • Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
  • Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
  • A form of rusticated masonry which is so wrought as to appear thickly indented with worm-tracks.
This word ultimately comes from the Latin 'vermis,' worm.
