Scientists now know that thunderstorms, working as powerful natural terrestrial particle accelerators, produce intense flashes of ionizing radiation called "dark lightning." To further their understanding of this phenomenon, researchers at the U.S. Naval Research Laboratory's...

In May 2013, researchers from UCLA, Iowa State and Princeton found a new way of sculpting tailor-made fluid flows by placing tiny pillars in microfluidic channels. By altering the speed of the fluid and stacking many pillars with different widths, placements, and orientations in the fluid's...

A small team of Monash University researchers working under the Australian Research Council (ARC) Centre of Excellence for Electromaterials Science (ACES) has developed an ionic liquid-based thermocell.

Researchers at the University of Southampton in the UK say that their MXL project, which uses computational modeling to define the mechanics of an artificial joint, will enable surgeons to ensure successful surgery and fit joint replacements with longer, optimized lifespans. Using a complex interaction...

A Victoria University of Wellington School of Design student, Jake Evill, in New Zealand, created a 3D printed alternative to the traditional plaster cast for fractured limbs. Called the Cortex Cast, his design is more lightweight, breathable, and hygienic than fiberglass or plaster casts currently...

Dr. Albert Chi, a 2003 graduate of the University of Arizona College of Medicine, Tucson, and a trauma surgeon at Johns Hopkins Hospital, Baltimore, MD, is part of a team of engineers and surgeons developing a Modular Prosthetic Limb—a robotic arm and hand that a person can control using their thoughts....

A team of scientists from UCLA, Iowa State, and Princeton report that they have discovered a new technique of sculpting custom fluid flows by placing tiny pillars in microfluidic channels. By altering the speed of the fluid, and stacking pillars with different width, placements, and orientations,...

Harnessing the computing power of ordinary citizens around the world could have the potential to accelerate the pace of health care research of all kinds, say a team of researchers from the Perelman School of Medicine at the University of Pennsylvania, Philadelphia. They say that “crowdsourcing,”...

Researchers at the Karlsruhe Institute of Technology, Germany, have created a three-piece 3D puzzle, with each piece less than 1 mm in size, which, they say, may be put together to make the smallest puzzle in the world. To create it, the researchers used a new process to manufacture the microstructures by casting...

The blades in compressors and turbines are subject to particularly high levels of stress and strain. The job of the blades is to convert fluid energy into mechanical energy. They ensure that aircraft engines generate the required thrust and that power plant generators produce sufficient electricity.

Human hearts from the potential donors that had been deemed unsuitable for transplantation could get a second chance to save a life, say a team of researchers at the University of Sunderland in collaboration with Newcastle University, both in the UK. The scientists are working to restart hearts and develop tests to prove...

Researchers from North Carolina State University have developed three-dimensional (3D) printing technology and techniques to create free-standing structures made of liquid metal at room temperature.

A Pentagon-financed humanoid robot named Atlas made its debut last week. The hydraulically-powered robot, with its oversized chest and powerful long arms, is seen as a new tool that can help humans in natural and man-made disasters. Similarly, an...

Military analysts now have a tool that brings together unprecedented modeling and simulation features to help them better choose, or build weapons to overpower future threats. Such features allow military researchers to analyze, for example, how a grenade, artillery round or any other weapon performs...

Simulation Helps Solve Mysteries of Water A research team from the National Physical Laboratory (NPL), the University of Edinburgh and IBM's TJ Watson Research Center achieved a major breakthrough in the modeling of water that could shed light on its mysterious properties.

By the year 2020, the European aviation industry wants to reduce emissions of gases harmful to the climate – carbon dioxide by 50 percent and nitrogen oxide by 80 percent – and also improve the lifecycles of the aircrafts themselves. “Life Cycle Assessment (LCA)” is the term experts...

A team of researchers from Brown University and Women & Infants Hospital of Rhode Island has developed a new computer-based tool to perform finely tuned acoustic analyses of babies’ cries. The team hopes their baby cry analyzer will lead to new ways for researchers and clinicians to use cry in...
