Road charges could ease Melbourne’s gridlock, research shows
Charging drivers at peak times could be the best way to help ease Melbourne's traffic woes, according to new research by the University of Melbourne. In a working paper,  Can Road Changes Alleviate Congestion , researchers Dr Leslie Martin and Mr Sam Thornton, from the Faculty of Business and Economics, analysed the economic and social impact of different charges levied on road use in Victoria.

Synthetic Muscle Gets Its Punch from Design Method
Researchers at Carnegie Mellon University's College of Engineering are taking a multidisciplinary approach to building synthetic muscles for applications in regenerative medicine and robotics. Each time a bicep flexes, millions of molecular motors work together in a complex process. These motors - called myosin - are chemically powered proteins.

Stick, peel, or bounce: Controlling a freezing droplet's fate
Stick, peel, or bounce: Controlling a freezing droplet’s fate
When freezing droplets impact a surface, they generally either stick to it or bounce away. Controlling this response is crucial to many applications, including 3-D printing, the spraying of some surface coatings, and the prevention of ice formation on structures such as airplane wings, wind turbines, or power lines.

A glimpse into a
A glimpse into a "masterpiece of engineering"
Research news More than 125 years ago, Otto Lilienthal laid the foundation for modern aviation with his innovative gliding apparatus, the "Normal Segelapparat". Only four specimens of the gliding apparatus have survived to this day, one of them at home in Deutsches Museum in Munich. Computer tomography investigations carried out by researchers at the Technical University of Munich (TUM) in collaboration with Airbus have for the first time provided a glimpse into the inner workings of the construction design.

Determining motor deficits more precisely following a stroke
Determining motor deficits more precisely following a stroke
Research news After a stroke, many people are unable to successfully perform basic hand movements in everyday life. The reason are symptoms of hemiparesis resulting from damage to the brain. These very frequently affect fine motor skills. A team from the Technical University of Munich (TUM) is now paving the way to better diagnosis and more targeted therapy.

Motorised molecules drill into cancer cells
Motorised molecules drill into cancer cells
Motorised molecules driven by light have been used to drill holes in the membranes of individual cells, including cancerous ones. The technique shows promise for either bringing therapeutic agents into the cells or directly inducing the cells to die. Dr Robert Pal at Durham University worked with researchers at Rice and North Carolina State universities in the USA to demonstrate in laboratory tests how rotors in single-molecule nanomachines can be activated by ultraviolet light to spin at two to three million rotations per second and open membranes in cells.

Experiments confirm theory of "superballistic" electron flow
When many people try to squeeze through a passageway at the same time, it creates a bottleneck that slows everyone down. It turns out the reverse is true for electrons, which can move through small openings more quickly when travelling in large groups than when flying solo. The theory of so-called superballistic flow predicts that electrons can pass more easily through constrictions by interacting with one another, and thereby "cooperating," than they can individually.

Prototype technology for unearthing minefields with fire developed by team
Engineers have developed prototype technology that uses controlled burning to partially reveal landmines buried in peat soil. The researchers from Imperial College London have developed technology called O-Revealer that ignites peat, causing a smouldering fire that strips the upper layer of soil to reveal the landmines - making it easier to dispose of them.

Using Light to Reach Higher Precision in Cell Mechanic Research
Using Light to Reach Higher Precision in Cell Mechanic Research
Not only muscle cells, but also all other cell types continually generate forces in the human body. An interdisciplinary cooperation of biologists and physicists including Heidelberg researcher Ulrich Schwarz now succeeded in performing high-resolution measurements of cell forces using light to switch them on and off in a controlled manner.

Motor neuron disease discovery offers new insights into potential treatment targets
Motor neuron disease discovery offers new insights into potential treatment targets
Scientists have discovered how certain forms of motor neuron disease begin and progress at cellular and molecular levels, revealing potential new ways to slow down or even stop this process. The team are already working closely with pharmaceutical companies to use this knowledge to develop new treatments for motor neuron disease and other neurodegenerative conditions.

New way to test self-driving cars could cut 99.9 percent of validation costs
ANN ARBOR?Mobility researchers at the University of Michigan have devised a new way to test autonomous vehicles that bypasses the billions of miles they would need to log for consumers to consider them road-ready. The process, which was developed using data from more than 25 million miles of real-world driving, can cut the time required to evaluate robotic vehicles' handling of potentially dangerous situations by 300 to 100,000 times.

Unbreakable quantum entanglement
Unbreakable quantum entanglement
Einstein's "spooky action at a distance" persists even at high accelerations, researchers of the Austrian Academy of Sciences and the University of Vienna were able to show in a new experiment. A source of entangled photon pairs was exposed to massive stress: The photons' entanglement survived the drop in a fall tower as well as 30 times the Earth's gravitational acceleration in a centrifuge.

Motor Neurons Tell Blood Vessels Where To Go
Heidelberg Neuroscientists have identified a critical regulator for blood vessel growth in the developing embryonic spinal cord. The research group under the direction of Dr Carmen Ruiz de Almodóvar of the Heidelberg University Biochemistry Center discovered that special nerve cells known as motor neurons control this process.

Stars align in test supporting ‘spooky action at a distance’
Quantum entanglement may appear to be closer to science fiction than anything in our physical reality. But according to the laws of quantum mechanics - a branch of physics that describes the world at the scale of atoms and subatomic particles - quantum entanglement, which Einstein once skeptically viewed as 'spooky action at a distance,' is, in fact, real.

Nanoparticles improve melting and solidification for manufacturing processes
Adding nanoscale particles of aluminum oxide increases the depth of the melting zone (MZ) in nickel and decreases the size of the heat-affected zone (HAZ). The bottom right image shows how even at higher temperatures the heat affected zone doesn't grow very large. I n an advance that could lead to improved manufacturing, a new study by UCLA researchers shows that adding nanoparticles to metals during the melting process allows for better control during melting.
