Naval Research Laboratory scientists analyze Comet Wild 2 samples
12-22-2006 · EurekAlert!Scientists at the Naval Research Laboratory have analyzed samples from Comet Wild 2, as part of NASA's Stardust mission, the first solid sample return mission since Apollo. Over 100 scientists at various institutions participated in the preliminary analysis. NRL contributed to the Mineralogy and Petrology, Crater, Bulk Chemistry and Isotope analysis teams by studying the structure and composition of the comet samples using transmission electron microscopy (TEM).

10-02-2007 · EurekAlert!
Scientists at the Naval Research Laboratory report they have captured the first images of a collision between a comet and a solar hurricane. It is the first time scientists have witnessed such an event on another cosmic body. One of NASA's pair of Solar Terrestrial Relations Observatory satellites, known as STEREO, recorded the event on April 20, 2007.

- Unlocking the frozen secrets of comet Wild 2
12-18-2006 · EurekAlert!
Eleven months ago, NASA's Stardust mission touched down in the Utah desert with the first solid comet samples ever retrieved from space. Since then, nearly 200 scientists from around the globe have studied the minuscule grains, looking for clues to the physical and chemical history of our solar system. Although years of work remain, researchers believe that comet Wild 2 contains some of the most primitive and exotic chemical structures ever studied in a laboratory.

- Scientists describe how 1918 influenza virus sample was exhumed in Alaska
07-02-2007 · EurekAlert!
In an article in the journal Antiviral Therapy, scientists at NIAID narrate the story of how scientists discovered samples of the 1918 strain in fixed autopsy tissues and in the body of a woman buried in the Alaskan permafrost. The article places this discovery in the context of decades of research into the cause of pandemic influenza, and the authors detail the strange convergence of events that allowed them to recover and sequence the virus in the first place.

- New buffer resists pH change, even as temperature drops
01-14-2008 · EurekAlert!
Researchers at the University of Illinois have found a simple solution to a problem that has plagued scientists for decades: the tendency of chemical buffers used to maintain the pH of laboratory samples to lose their efficacy as the samples are cooled. The research team, headed by chemistry professor Yi Lu, developed a method to formulate a buffer that maintains a desired pH at a range of low temperatures.

Primetime crime drama meets reality in forensic research taking place at the Midwest Forensics Resource Center at Iowa State University. US Department of Ames Laboratory scientists are using the new Direct Analysis in Real Time (DART) mass spectrometry interface, which has made a guest appearance on the popular crime show CSI: New York, to build a library of ink mass spectra using samples from the US Secret Service. The mass spectra library will help identify inks on fraudulent documents and other crime evidence.

- NRL scientists produce carbon nanotubes using commercially available polymeric resins
02-07-2008 · EurekAlert!
Scientists at the Naval Research Laboratory have successfully produced carbon nanotubes in high yields in bulk solid compositions using commercially available aromatic containing resins. The concentration of multi-walled carbon nanotubes and metal nanoparticles can be easily varied within the shaped carbonaceous solid. Carbon nanotube containing fibers and films have also been formulated from the precursor compositions. The potential range of applications is huge, including structure, energy, sensors, separation/filtration, battery, electronic displays and nanoelectronic devices.
