Greater potential for low-cost solar power plants
Greater potential for low-cost solar power plants
New analysis of large-scale 'concentrating solar power' plants suggests they could meet 70-80% of electricity demand if they are linked together. In a new study published Climate Change, researchers from the Grantham Institute at Imperial College London, Stellenbosch University , and the International Institute for Applied Systems Analysis (IIASA) have calculated for the first time that connecting 'concentrating solar power' (CSP) plants could supply a significant amount of current electricity demand, alleviating concerns over the reliability and intermittency of renewable power.

Spiders know the meaning of web music
Spider silk transmits vibrations across a wide range of frequencies so that, when plucked like a guitar string, its sound carries information about prey, mates, and even the structural integrity of a web. The discovery was made by researchers from the Universities of Oxford, Strathclyde, and Sheffield who fired bullets and lasers at spider silk to study how it vibrates.

Stem cells take initial step toward development in the lab
Stem cells take initial step toward development in the lab
CHAMPAIGN, Ill. The gap between stem cell research and regenerative medicine just became a lot narrower, thanks to a new technique that coaxes stem cells, with potential to become any tissue type, to take the first step to specialization. It is the first time this critical step has been demonstrated in a laboratory.

Scientists at Stanford and MIT find new way to harness waste heat
Researchers have developed a new battery technology that captures waste heat and converts it into electricity. Vast amounts of excess heat are generated by industrial processes and by electric power plants. Researchers around the world have spent decades seeking ways to harness some of this wasted energy.

Engineers Build World’s Smallest, Fastest Nanomotor
AUSTIN, Texas -áResearchers at the Cockrell School of Engineering at The University of Texas at Austin have built the smallest, fastest and longest-running tiny synthetic motor to date. The team's nanomotor is an important step toward developing miniature machines that could one day move through the body to administer insulin for diabetics when needed, or target and treat cancer cells without harming good cells.

Scientists use nanoparticles to control growth of materials
Scientists use nanoparticles to control growth of materials
UCLA-led team creates 'diet control' technique that could have broad applications in manufacturing and medicine Matthew Chin Growth is a ubiquitous phenomenon in plants and animals. But it also occurs naturally in chemicals, metals and other inorganic materials. That fact has, for decades, posed a major challenge for scientists and engineers, because controlling the growth within materials is critical for creating products with uniform physical properties so that they can be used as components of machinery and electronic devices.

Researchers create ‘ultrasonic hands’ that can grip microparticles
Press release issued: 14 May 2014 A team of researchers from the Universities of Bath, Bristol and Dundee has discovered for the first time that ultrasonic waves can be used to grab several microparticles at a time, effectively creating a pair of invisible 'ultrasonic hands' that can move tiny objects, such as cells, under a microscope.

Magnetic topological insulators developed at UCLA are 1,000 times more energy-efficient for switching
Topological insulators are an emerging class of materials that act as both insulators and conductors, and could potentially be used in smartphones, computers and other electronic devices. A research team at the UCLA Henry Samueli School of Engineering and Applied Science has developed a new class of topological insulators in which one of two layers is magnetized.

All in the Rotation
All in the Rotation
Viruses are the enigma of the biological world - despite having their own DNA and being able to adapt to their environment and evolve, they are not considered to be alive like cells. In order to reproduce and multiply - a requirement of "life" – a virus must invade a living cell, eject its DNA into that of the cell, and commandeer the cell's biological machinery.

New shape using rubber bands
While setting out to fabricate new springs to support a cephalopod-inspired imaging project, a group of Harvard researchers stumbled upon a surprising discovery: the hemihelix, a shape rarely seen in nature. This made the researchers wonder: Were the three-dimensional structures they observed randomly occurring, or are there specific factors that control their formation? The scientists answered that question by performing experiments in which they stretched, joined, and then released rubber strips.

Glasses strong as steel: A fast way to find the best
Glasses strong as steel: A fast way to find the best
Scientists at Yale University have devised a dramatically faster way of identifying and characterizing complex alloys known as bulk metallic glasses (BMGs), a versatile type of pliable glass that's stronger than steel. Using traditional methods, it usually takes a full day to identify a single metal alloy appropriate for making BMGs.
