3D printing techniques have quickly become some of the most widely used tools to rapidly design and build new components. A team of engineers at the University of Bristol has developed a new type of 3D printing that can print composite materials, which are used in many high performance products such as tennis rackets, golf clubs and aeroplanes. This technology will soon enable a much greater range of things to be 3D printed at home and at low-cost.
Researchers from MIPT have found a solution to the problem of overheating of active plasmonic components. These components will be essential for high-speed data transfer within the optoelectronic microprocessors of the future, which will be able to function tens of thousands of times faster than the microprocessors currently in use today. In the paper published in ACS Photonics the researchers have demonstrated how to efficiently cool optoelectronic chips using industry-standard heatsinks in spite of high heat generation in active plasmonic components.
EPFL scientists have developed a solar-panel material that can cut down on photovoltaic costs while achieving competitive power-conversion efficiency of 20.2%.
An international team of researchers has taken a step toward achieving controlled nuclear fusion--a process that powers the Sun and other stars, and has the potential to supply the world with limitless, clean energy.
A new study from the Medical Research Council Lifecourse Epidemiology Unit, University of Southampton, shows lesions, which can best be seen on MRI scans, could help identify individuals who are more likely to suffer from more rapidly progressing osteoarthritis.
Osteoarthritis is the most common type of arthritis in the UK and can cause the joints to become painful and stiff. Almost any joint can be affected, but it most often causes problems in the knees, hips, and small joints of the hands. It can progress at varying speeds.
"Planes, Trains and Automobiles" is a popular comedy from the 1980s, but there's nothing funny about the amount of energy consumed by our nation's transportation sector.
This sector -- which includes passenger cars, trucks, buses, and rail, marine, and air transport -- accounts for more than 20 percent of America's energy use, mostly in the form of fossil fuels, so the search is on for environmentally friendly alternatives.
LA JOLLA--Mitochondria, the power generators in our cells, are essential for life. When they are under attack--from poisons, environmental stress or genetic mutations--cells wrench these power stations apart, strip out the damaged pieces and reassemble them into usable mitochondria.
Scientists predict a major range contraction of chytrid in Africa's Albertine Rift over the next century.
Climate models predict warmer and wetter conditions in this region may cause changes in habitat suitability that are less favorable for chytrid
Chytrid is wiping out amphibians worldwide but study indicates some resistance in the Albertine Rift
Researchers in the Cockrell School of Engineering at The University of Texas at Austin have solved a problem in micro- and nanofabrication -- how to quickly, gently and precisely handle tiny particles -- that will allow researchers to more easily build tiny machines, biomedical sensors, optical computers, solar panels and other devices.
A group of researchers from Russia, Australia and the Netherlands have developed a technology that can reduce Magnetic Resonance Imaging (MRI) scanning times by more than 50%, meaning hospitals can drastically increase the number of scans without changing equipment. This extraordinary leap in efficiency is achieved by placing a layer of metamaterials onto the bed of the scanner, which improves the signal-to-noise ratio. The details of this experimental research are available in the current issue of Advanced Materials.
The centre ground of British politics could be further to the left than we think, according to new research by the University of Sussex and Queen Mary University of London.
A study into the views of supporters of the main political parties in the country suggests that many are more left wing than they think they are.
Stringent climate policies would increase the cost of fossil fuels, including those used for the cleaner burning stoves (such as kerosene, liquefied petroleum gas, electricity, and piped gas) that are slowly replacing traditional cooking fuels. Without simultaneous targeted efforts to increase funding for energy access, many who would otherwise have been able to switch from traditional solid fuels to modern cooking fuels would no longer be able to afford the switch, according to a study published in the first issue of the new journal Nature Energy.
Scientists from the University of Southampton have uncovered evidence of a previously unknown large volcanic eruption in the Caribbean Sea.
By studying ash layers, known as tephras, in marine sediments they identified an eruption that took place on Guadeloupe 2.4 million years ago.
The research, published in the journal Geology, indicates this eruption is the largest documented volcanic event in the region since that time.
Could alcohol abstinence campaigns like Dry January do more harm than good? Two experts debate the issue in The BMJ today.
Lack of evidence that such campaigns work and don't have unintended consequences, concerns Ian Hamilton, a lecturer at York University.
The Dry January campaign estimates that "Last year over 2 million people cut down their drinking for January," he writes. But popular doesn't necessarily mean effective, and he argues that this type of campaign "has had no rigorous evaluation."
Target dates are critical when the semiconductor industry adds small, enhanced features to our favorite devices by integrating advanced materials onto the surfaces of computer chips. Missing a target means postponing a device's release, which could cost a company millions of dollars or, worse, the loss of competitiveness and an entire industry. But meeting target dates can be challenging because the final integrated devices, which include billions of transistors, must be flawless - less than one defect per 100 square centimeters.
