Experts build pulsed air rig to test 3D printed parts for low carbon engines
Researchers designed a unique facility for testing 3D printed engine parts, to help reduce carbon emissions worldwide. The new Transient Air System Rig (TASR) was designed and built by Dr Aaron Costall and his team from Imperial College London's Department of Mechanical Engineering. The researchers hope it will help makers of large off-road and freight vehicles reduce the amount of carbon dioxide (CO 2 ) they produce.

The underwater adhesive
The underwater adhesive
A special formula for epoxy resins has been developed at TU Wien, which can be used for fibre-reinforced composites in aerospace, shipbuilding and automotive manufacturing, or even for underwater renovation. This is achieved merely by irradiating any part of the resin with light. Within seconds the new material can be completely transformed.

Consumers quickly learn what environmentally friendly looks like
Without realizing it, our brains quickly learn to associate certain visual cues - a curve of a car or color of a product - with certain attributes, such as its environmental friendliness. You can't judge a book by its cover, goes the saying. Yet, that's exactly what people do, according to new research from Stanford mechanical engineer Erin MacDonald and visiting researcher Ping Du.

Going with the flow
Going with the flow
Is sand a solid, a liquid, or a gas' It's a question that has plagued scientist for centuries. If a jogger runs on a beach, sand acts as a solid and supports their weight. Put it in an hourglass, and sand pours through the nozzle, much like a liquid. If a child in a sandbox trips and kicks up a cloud of sand, the separated grains collide and interact as though it's a gas.

Shen Puts High-Tech Spin on Polymers
Strong, lightweight, thermal nanofibers could be used in many industries Sheng Shen is Carnegie Mellon University's Spiderman. When the associate professor of mechanical engineering talks about his work with polymer nanofibers, he compares it to a spider spinning its web. "Just as a spider synthesizes silk from protein polymer to form a fiber with strength similar to high tensile steel, polymers can be spun and drawn to form high-strength materials with exceptionally high thermal conductivity," said Shen, associate professor of mechanical engineering at Carnegie Mellon University.

Fish in schools can take it easy
Fish in schools can take it easy
Using a new computer model, researchers at the Ecole Centrale de Marseille and CNRS have shown that a fish expends less energy when it swims in a school, because neighbouring fish produce a 'suction' effect. This work will be published on 11 May 2018 in Physical Review Letters . Schools of fish provide a fascinating example of collective behaviour in which the group moves in a coordinated manner without the need for a leader.

Koman Family Outpatient Pavilion at UC San Diego Health Dedicated
An innovative, eel-like robot developed by engineers and marine biologists at the University of California can swim silently in salt water without an electric motor. Instead, the robot uses artificial muscles filled with water to propel itself. The foot-long robot, which is connected to an electronics board that remains on the surface, is also virtually transparent.

Einstein-Podolsky-Rosen paradox observed in many-particle system for the first time
Einstein-Podolsky-Rosen paradox observed in many-particle system for the first time
Physicists from the University of Basel have observed the quantum mechanical Einstein-Podolsky-Rosen paradox in a system of several hundred interacting atoms for the first time. The phenomenon dates back to a famous thought experiment from 1935. It allows measurement results to be predicted precisely and could be used in new types of sensors and imaging methods for electromagnetic fields.

Putting the future of flying to the test
Putting the future of flying to the test
The world's most powerful aerospace gearbox will go into service in 2025: It is part of the Rolls-Royce UltraFan design and will transfer up to 100,000 hp. In a project supported by the German federal government, scientists at the Technical University of Munich (TUM) are investigating how the gearbox's properties vary according to size and how they can be optimized.

Taylor Puts New Twist on Measuring Stress in Materials
The U.S. Air Force has awarded Assistant Professor of Mechanical Engineering Rebecca Taylor funding to develop "nanosprings" that could stick to soft materials or be sprayed onto metals to estimate the mechanical stress a piece of machinery endures. The nanosprings would allow mechanics and engineers to monitor the integrity and function of mechanical equipment, such as struts or aircraft components.

Combining scientific languages to create an invisibility cloak
An assistant professor at Brussels' Vrije Universiteit and a visiting professor at Harvard, Vincent Ginis is a brilliant scientist who won a Solvay Award in 2014 and was designated as one of the top 50 tech pioneers in Belgium in 2017. His particular area of study is optics, but he makes a strong case for the combination of different scientific disciplines, or “languages”, to drive progress in research.

Acoustic blockage-detection system could prevent aircraft accidents
Acoustic blockage-detection system could prevent aircraft accidents
Pitots, which provide airspeed data, have played a role in several aircraft accidents, including the fatal Air France Flight 447 in 2009. New research by aerospace engineers at the University of Bristol has found that an acoustic blockage-detection system could prevent future accidents by making pilots aware of a blocked Pitot before a situation becomes critical.

Tissue mechanics essential for cell movement
Cells that form facial features need surrounding embryonic tissues to stiffen so they can move and develop, according to new UCL-led research. The discovery has important implications for understanding the causes of facial defects which account for a third of all birth defects globally (3.2 million each year) and are the primary cause of infant mortality.

Automating materials design
Automating materials design
For decades, materials scientists have taken inspiration from the natural world. They'll identify a biological material that has some desirable trait - such as the toughness of bones or conch shells - and reverse-engineer it. Then, once they've determined the material's "microstructure," they'll try to approximate it in human-made materials.

Artificial sounds for traffic safety
Artificial sounds for traffic safety
Research news The almost complete silence of the motors used in electric cars may pose a hazard to inattentive pedestrians. As a result, starting in summer 2019 all new electric and hybrid vehicles will have to be equipped with an acoustic warning system. Psychoacousticians at the Technical University of Munich (TUM) are developing the corresponding sounds.

Feedback enhances brainwave control of a novel hand-exoskeleton
EPFL scientists are developing a lightweight and portable hand exoskeleton that can be controlled with brainwaves. The device enhances performance of brain-machine interfaces and can restore functional grasps for the physically impaired. An extremely lightweight and portable hand exoskeleton may one day help the physically impaired with daily living.

How the temperature of your nose shows how much strain you are under
Researchers at the University of Nottingham's Institute for Aerospace Technology (IAT), together with academic staff from the Bioengineering and Human Factors Research Groups, have demonstrated that facial temperatures, which can be easily measured using a non-invasive thermal camera, are strongly correlated to mental workload.

Breast cancer research gets a mechanical boost
Stanford researchers say one way to solve the mystery of why some breast cancers are more likely to spread could come from studying the cell's mechanical properties. Ovijit Chaudhuri and his lab are studying how mechanical properties of breast tissue influence tumor cells. (Image credit: Courtesy Department of Mechanical Engineering) One of the most puzzling questions in breast cancer research is why some tumors stay put, while rogue cells from others break free and spread to surrounding tissues, the first step toward creating a more lethal disease.

How bacteria turbocharged their motors
How bacteria turbocharged their motors
Using detailed 3D images, researchers have shown how bacteria have evolved molecular motors of different powers to optimize their swimming. The discovery, by a team from Imperial College London, provides insights into evolution at the molecular scale. Bacteria use molecular motors just tens of nanometres wide to spin a tail (or ‘flagellum') that pushes them through their habitat.
