After devising several new and promising "green" flame retardants for furniture padding, NIST researchers took a trip to the grocery store and cooked up their best fire-resistant coatings yet. As important, these protective coatings can be made in one straightforward step.
A newly developed spectroscopy method is helping to clarify the poorly understood molecular process by which an anti-HIV drug induces lethal mutations in the virus’ genetic material. The findings from the Univ. of Chicago and the Massachusetts Institute of Technology could bolster efforts to develop the next generation of anti-viral treatments.
The mesh coating is among a suite of nature-inspired nanotechnologies under development at Ohio State and described in two papers in Nature Scientific Reports. Potential applications range from cleaning oil spills to tracking oil deposits underground.
NIST researchers have demonstrated the most precise method yet to measure the structural configuration of monoclonal antibodies, an important factor in determining the safety and efficacy of these biomolecules as medicines. Monoclonal antibodies are proteins manufactured in the laboratory that can target specific disease cells or antigens (proteins that trigger an immune reaction) for removal from the body.
Cool roofs can help keep buildings cool, thus lowering the building’s energy use, while also mitigating the urban heat island effect by reflecting sunlight away from buildings and cities. But as cool roofs age and get soiled, how much of their reflectance do they lose?
Rice Univ. researchers have determined that two walls are better than one when turning carbon nanotubes into materials like strong, conductive fibers or transistors. Rice materials scientist Enrique Barrera and his colleagues used atomic-level models of double-walled nanotubes to see how they might be tuned for applications that require particular properties.
Imagine having your MRI results sent directly to your phone, with no concern over the security of your private health data. Or knowing your financial information was safe on a server halfway around the world. Or sending highly sensitive business correspondence, without worrying that it would fall into the wrong hands.
Electrical charges not only move through wires, they also travel along lengths of DNA, the molecule of life. The property is known as charge transport. In a new study appearing in Nature Chemistry, researchers explore the ways in which electrical charges move along DNA bases affixed to a pair of electrodes.
Scientists focused on producing biofuels more efficiently have a new powerful data set to help them study the DNA of microbes that fuel bioconversion and other processes. In a recently published paper, researchers describe methods and results for sequencing the Clostridium autoethanogenum bacterium. These and other microorganisms play important roles in biofuels, agriculture, food production, the environment, health and disease.
NASA's Spitzer Space Telescope has teamed up with a telescope on the ground to find a remote gas planet about 13,000 light-years away, making it one of the most distant planets known. The discovery demonstrates that Spitzer can be used to help solve the puzzle of how planets are distributed throughout our flat, spiral-shaped Milky Way galaxy. Are they concentrated heavily in its central hub, or more evenly spread throughout its suburbs?
The Relativistic Heavy Ion Collider just shattered its own record for producing polarized proton collisions at 200-GeV collision energy. In the experimental run currently underway at this two-ringed, 2.4-mile-circumference particle collider, accelerator physicists are now delivering 1,200 billion of these subatomic smashups per week.
Those lost car keys that were an annoyance in your 30s can spark major anxiety in your 60s. Turns out it's pretty normal: The brain ages just like the rest of your body, says a new report that urges Americans to take steps to keep sharp in their senior years. The prestigious Institute of Medicine examined what scientists know about "cognitive aging," changes in mental functioning as we get older.
Additive manufacturing has been called a game changer. But new games require new instructions, and the manuals for a growing assortment of methods for building parts and products layer-by-layer, collectively known as "3D printing", still are works in progress. Manufacturing researchers at NIST have scoped out the missing sections in current guidelines for powder bed fusion, the chief method for "printing" metal parts.
A new material developed at the Univ. of Colorado Boulder could radically reduce the energy needed to produce a wide variety of plastic products, from grocery bags and cling wrap to replacement hips and bulletproof vests. Approximately 80 million metric tons of polyethylene is produced globally each year, making it the most common plastic in the world.
More than 50 years ago, when the laser was a mere five years old, laser physicists dreamed of the development of an x-ray laser to expand the frontier of knowledge. The concept goes back to the mid-1960s, when scientists realized that laser beams amplified with ions would have much shorter wavelengths than beams amplified with gas.
