Researchers at NASA‘s Jet Propulsion Laboratory (JPL), California Institute of Technology, and Pennsylvania State University have developed a 3D printing process that transitions from one metal or alloy to another in a single object. For example, they created a prototype of an improved telescope mirror mount. The part at the top near the glass mirror is

(Massachusetts Institute of Technology) A team of researchers has created a new way of manufacturing microstructured surfaces that have novel three-dimensional textures. These surfaces, made by self-assembly of carbon nanotubes, could exhibit a variety of useful properties -- including controllable mechanical stiffness and strength, or the ability to repel water in a certain direction.

(Springer) Swimming microorganisms are subjected to relatively small inertial forces compared to the viscous forces exerted by the surrounding fluid. Such low-level inertia makes self-propulsion a major challenge. Scientists have found that the direction of propulsion made possible by such inertia is opposite to that induced by a viscoelastic fluid. This study published in EPJ E could help optimise the design of self-propelled micro- and nano-sca... More

A new study led by MIT materials scientists reveals the reason why gold nanoparticles  can easily slip through cell membranes to deliver drugs directly to target cells. The nanoparticles enter cells by taking advantage of a route normally used in vesicle-vesicle fusion, a crucial process that allows signal transmission between neurons. In the July 21

University of Pennsylvania researchers have used a cutting-edge microscope to study the relationship between the atomic geometry of a ribbon of graphene and its electrical properties. A deeper understanding of this relationship will be necessary for the design of graphene-based integrated circuits, computer chips, and other electronic devices. The study was published in the journal

Rutgers researchers have used carbon nanotubes as a catalyst for splitting water into hydrogen and oxygen, which could replace expensive platinum for making clean-burning hydrogen fuel — which could one day replace expensive, environmentally harmful fossil fuels. The Rutgers technology is also far more efficient than other low-cost catalysts investigated to date for electrolysis reactions,

Ancient fossilized soils potentially found deep inside an impact crater suggest microbial life. Soil deep in a crater dating to some 3.7 billion years ago contains evidence that Mars was once much warmer and wetter, says University of Oregon geologist Gregory Retallack, based on recent images from Curiosity. The images from the impact Gale Crater,

University of Texas Austin researchers have developed a tiny prototype microphone device that mimics the Ormia ochraceafly's hearing mechanism. The design may be useful for a new generation of hypersensitive, millimeter-sized, low-power hearing aids. The yellow-colored Ormia ochracea fly, the inspiration for the design, can pinpoint the location of a chirping cricket with remarkable accuracy because

By 2050, the number of people over the age of 80 will triple globally, which could come at great cost to individuals and economies. Unfortunately, medicine focuses almost entirely on fighting chronic diseases in a piecemeal fashion as symptoms develop, researchers writing in the journal Nature say. Instead, more efforts should be directed to promoting interventions

We might be able to spot extraterrestrial civilizations if we assume they spew industrial pollution into the atmosphere, say theorists at the Harvard-Smithsonian Center for Astrophysics (CfA). Conversely, ET could spot us. The team suggests that under ideal conditions, the upcoming James Webb Space Telescope (JWST) should be able to detect two kinds of chlorofluorocarbons
