Light traveling in a vacuum is the Universe’s ultimate speed demon, racing along at approximately 300,000 kilometers per second. Now scientists have found an effective new way to put a speed bump in light’s path.
A team at the University of California, Riverside Bourns College of Engineering has developed a novel way to build what many see as the next generation memory storage devices for portable electronic devices including smart phones, tablets, laptops and digital cameras.
Researchers at the University of Rochester have measured for the first time light emitted by photoluminescence from a nanodiamond levitating in free space. In a paper published this week in Optics Letters, they describe how they used a laser to trap nanodiamonds in space, and – using another laser – caused the diamonds to emit light at given frequencies.
Climate change alters the way in which species interact with one another--a reality that applies not just to today or to the future, but also to the past, according to a paper published by a team of researchers in this week's issue of the journal Science.
Strokes can often leave victims in deblitating situations suffering everything from amnesia to migrains. The results are often tragic. Yet, one man seems to have suffered a happy incidence of his stroke, one that makes him the life of the party.
According to a story in Britains Daily Telegraph:
Computer simulations have revealed how the electrical conductivity of many materials increases with a strong electrical field in a universal way. This development could have significant implications for practical systems in electrochemistry, biochemistry, electrical engineering and beyond.
One of the biggest mysteries in contemporary particle physics and cosmology is why dark energy, which is observed to dominate energy density of the universe, has a remarkably small (but not zero) value. This value is so small, it is perhaps 120 orders of magnitude less than would be expected based on fundamental physics.
An evolutionary ecologist at the University of Southampton, is using 'grains of sand' to understand more about the process of evolution. Dr Thomas Ezard is using the fossils of microscopic aquatic creatures called planktonic foraminifera, often less than a millimetre in size, which can be found in all of the world's oceans.
Bending light beams to your whim sounds like a job for a wizard or an a complex array of bulky mirrors, lenses and prisms, but a few tiny liquid bubbles may be all that is necessary to open the doors for next-generation, high-speed circuits and displays, according to Penn State researchers.
A lot of people mix up the ozone hole and global warming, believing the hole is a major cause of the world’s increasing average temperature. Scientists, on the other hand, have long attributed a small cooling effect to the ozone shortage in the hole.
Researchers at JILA have for the first time used an atomic clock as a quantum simulator, mimicking the behavior of a different, more complex quantum system.
You are more likely to kill yourself reading this article than you are talking on your cellphone and driving. That's our guess, but for almost 20 years, it has been a wide-held belief that talking on a cellphone while driving is dangerous and leads to more accidents. However, new research from Carnegie Mellon University and the London School of Economics and Political Science suggests that talking on a cellphone while driving does not increase crash risk.
Scientists have created a powerful micro-supercapacitor, just nanometres thick, that could help electronics companies develop mobile phones and cameras that are smaller, lighter and thinner than ever before.
Researchers at Columbia University Medical Center, working with their collaborators at the Hospital for Special Surgery, have created a fleet of molecular "robots" that can home in on specific human cells and mark them for drug therapy or destruction.
Researchers at the Niels Bohr Institute, together with colleagues in the US and Australia, have developed a method to control a quantum bit for electronic quantum communication in a series of quantum dots, which behave like artificial atoms in the solid state. The results have been published in the scientific journal Physical Review Letters.
Once a James Bond fantasy, diamond-based lasers are now becoming a reality.
Molecules could soon be “scanned” in a fashion similar to imaging screenings at airports, thanks to a detector developed by University of Pittsburgh physicists.
Future warming from fossil fuel burning could be more intense and longer-lasting than previously thought. This prediction emerges from a new study by Richard Zeebe at the University of Hawai'i who includes insights from episodes of climate change in the geologic past to inform projections of man-made future climate change.
Online game companies need to be more socially responsible for over-addictive use of their products to avoid government intervention, according to a new study by Cardiff, Derby and Nottingham Trent universities.
Researchers from North Carolina State University have developed a new technique for creating devices out of a water-based hydrogel material that can be patterned, folded and used to manipulate objects. The technique holds promise for use in "soft robotics" and biomedical applications.
