Touchscreens may improve motor skills in toddlers
A new study by researchers from King's College London and Birkbeck, University of London, has found that toddlers who use touchscreens may show improved fine motor control abilities. The use of touchscreens has increased rapidly in recent years, with statistics showing that in the UK alone, the number of touchscreen devices in the family home has increased from 7 per cent in 2011 to 71 per cent in 2014.

Shape-changing metamaterial developed using Kirigami technique
Shape-changing metamaterial developed using Kirigami technique
Engineers from the University of Bristol have developed a new shape-changing metamaterial using Kirigami, which is the ancient Japanese art of cutting and folding paper to obtain 3D shapes. Metamaterials are a class of material engineered to produce properties that don't occur naturally. Currently metamaterials are used to make artificial electromagnetic and vibration absorbers and high-performance sensors.

Method opens a window on how stress and strain affect battery performance
CHAMPAIGN, Ill. — Batteries that charge faster and have greater capacity could boost portable electronic devices and electric cars. A new method to simultaneously test stress and strain in battery electrodes gives researchers a window into the mechanical, electrical and chemical forces within lithium-ion batteries.

Leonardo da Vinci’s irrelevant? scribbles mark the spot where he first recorded the laws of friction
A new detailed study of notes and sketches by Leonardo da Vinci has identified a page of scribbles in a tiny notebook as the place where Leonardo first recorded the laws of friction.

Big Thinking in Small Pieces: Computer Guides Humans in Crowdsourced Research
The Knowledge Accelerator, uses a machine-learning program to sort and organize information. Getting a bunch of people to collectively research and write a coherent report without any one person seeing the big picture may seem akin to a group of toddlers producing Hamlet by randomly pecking at typewriters.

Researchers improve understanding of ’Silly Putty’ protein that could improve bioengineered tissues
New insights into the characteristics of collagen, the protein that provides structure and stability for cells but which also stretches like Silly Putty, could help scientists design techniques for regenerating tissues. Collagen is an essential protein for living tissue. It forms the stiff scaffolding that provides structure and stability for tissues and the cells within them.

Wind turbine study measures small effect on local climate
Wind turbine study measures small effect on local climate
Newly published research has shown that the action of wind turbines has a measurable effect on the local climate. Researchers from Lancaster University, the Centre for Ecology & Hydrology, National Centre for Atmospheric Science, the University of Glasgow, and the University of Leeds placed a grid of more than 100 temperature and humidity sensors around wind turbines at ScottishPower Renewables' Black Law Wind Farm in North Lanarkshire.

Windfarms generate microclimates with uncertain effects on peatland carbon store
The microclimates created by the action of wind farms is unlikely to affect the ability of peatland to capture carbon, scientists consider. Previous studies by other researchers have established that wind farms do create localised microclimates, with slightly different temperatures and levels of humidity caused by the action of the turbine blades.

Mechanics of the cell
Mechanics of the cell
Living cells must alter their external form actively, otherwise functions like cell division would not be possible. At the Technical University of Munich (TUM) the biophysicist Professor Andreas Bausch and his team have developed a synthetic cell model to investigate the fundamental principles of the underlying cellular mechanics.

A Mechanical Feedback Restricts Sepal Growth and Shape in Arabidopsis
A research team of the Laboratory of Plant Reproduction and Developmen t (RDP - Inra, ENS de Lyon, CNRS, Université Claude Bernard Lyon 1), has just revealed that organs sense their own growth and can therefore control their final shape.

Social thinking in the infant brain
An innovative collaboration between neuroscientists and developmental psychologists that investigated how infants' brains process other people's actions provides the first evidence that directly links neural responses from the motor system to overt social behavior in infants. The research will be published April 12 in Psychological Science , the peer-reviewed journal of the Association for Psychological Science.

Motor learning tied to intelligent control of sensory neurons in muscles
Sensory neurons in human muscles provide important information used for the perception and control of movement. Learning to move in a novel context also relies on the brain's independent control of these sensors, not just of muscles, according to a new study published in the journal Current Biology.

Sensitive quantum particles
Sensitive quantum particles
The quantum mechanical entanglement of particles plays an important role in many technical applications. To date, however, the effect has been difficult to measure experimentally. Physicists from the Technical University of Munich (TUM), the University of Innsbruck and the Institute of Photonic Sciences (ICFO) in Barcelona have now developed a new protocol to detect entanglement of many-particle quantum states using established measuring methods.

An Up-Close View of Bacterial "Motors"
Bacteria are the most abundant form of life on Earth, and they are capable of living in diverse habitats ranging from the surface of rocks to the insides of our intestines. Over millennia, these adaptable little organisms have evolved a variety of specialized mechanisms to move themselves through their particular environments.

Doctors find the first effective treatment to calm delirious critically ill patients
Critically ill patients in intensive care commonly become delirious and agitated during treatment, causing them to pull out breathing tubes and interfere with other essential medical devices. Now a study led by The University of Queensland has shown that patient delirium and agitation can be reduced by administering a little-used drug known as dexmedetomidine.

Foetal motor neuron imbalance can hard-wire later problems, researchers say
Motor neuron connections are refined in the weeks before and just after birth, and they are crucial for normal development later, University of Queensland research suggests. The discovery could lead to a better understanding of developmental disorders such as autism and epilepsy, say two School of Biomedical Sciences neuroscientists, Associate Professors Peter Noakes and Mark Bellingham.

Three "twisted" photons in three dimensions
Researchers at the Institute of Quantum Optics and Quantum Information (IQOQI), the University of Vienna, and the Universitat Autonoma de Barcelona have achieved a new milestone in quantum physics: they were able to entangle three particles of light in a high-dimensional quantum property related to the "twist" of their wavefront structure.

A fifth of car fuel-efficiency savings are eroded by increased driving Around a fifth of the energy-saving benefits of fuel-efficient cars are eroded because people end up driving them more, according to a study into British motoring habits over the last 40 years. Using data from 1970 to 2011, energy experts at the University of Sussex found a long-term 'rebound effect' among British car-drivers of around 20 per cent.

Motorboat noise gives predators a deadly advantage
Motorboat noise gives predators a deadly advantage
The rate that fish are captured by predators can double when boats are motoring nearby, according to pioneering work led by the University of Exeter and co-authored by the University of Bristol, published today in Nature. Dr Stephen Simpson of Exeter's Biosciences department and an international research team, including Bristol's Dr Andy Radford , found that noise from passing motorboats increases stress levels in young coral reef fish and reduces their ability to flee from predators.
