First graders fitter than expected
Research news Childhood obesity is often attributed to a lack of exercise. So what about sports among elementary school students' A team from the Technical University of Munich (TUM) pursued this question and collected the results of fitness tests for first-year students over a period of one decade. Their study shows that students did not lose their strength.

Winds of change for vertical axis turbines?
New research suggests vertical axis turbines, which may have fewer impacts on birds and the environment, could increase public support for new wind energy installations. With global carbon emissions on the rise, wind power continues to be an attractive option for states and countries looking to limit fossil fuel use and increase renewable energy.

Liquid shock absorbers
Liquid shock absorbers
Researchers have determined how certain liquids stiffen in response to powerful impacts. At first glance, colloids resemble homogeneous liquids such as milk or blood plasma. But in fact they consist of particles in suspension. Some colloids have remarkable properties: they may stiffen following an impact and absorb surface shocks.

Chromosomes 'Cheat' for the Chance to Get Into an Egg
Chromosomes ’Cheat’ for the Chance to Get Into an Egg
Each of your cells contains two copies of 23 chromosomes, one inherited from your father and one from your mother. Theoretically, when you create a gamete - a sperm or an egg - †each copy has a 50-50 shot at being passed on. But the reality isn't so clearcut. Scientists have observed that chromosomes can "cheat," biasing the chance that they will make it into a sex cell.

Hydroelectric power plants have to be adapted for climate change
Of all the electricity produced in Switzerland, 56% comes from hydropower. The life span of hydroelectric plants, which are massive and expensive to build and maintain, is measured in decades, yet the rivers and streams they depend on and the surrounding environment are ever-changing.

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 "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
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
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
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.

Structure and mechanics of aegagropilae fiber network
Structure and mechanics of aegagropilae fiber network
Abstract Fiber networks encompass a wide range of natural and manmade materials. The threads or filaments from which they are formed span a wide range of length scales: from nanometers, as in biological tissues and bundles of carbon nanotubes, to millimeters, as in paper and insulation materials. The mechanical and thermal behavior of these complex structures depends on both the individual response of the constituent fibers and the density and degree of entanglement of the network.

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.
