Where the river meets the sea, there is the potential to harness a significant amount of renewable energy, according to a team of mechanical engineers. The researchers evaluated an emerging method of power generation, called pressure retarded osmosis, in which two waters of different salinity are mixed to produce energy.
A team of researchers has developed a new type of solar concentrator that, when placed over a...
Anyone who has ever had a glass of fizzy soda knows that bubbles can throw tiny particles into...
Man-made earthquakes, a side effect of some high-tech energy drilling, cause less shaking and in general are about 16 times weaker than natural earthquakes with the same magnitude.
Physicists have developed new technology to study atomic vibration in small particles, revealing a more accurate picture of the structure of atomic clusters where surface atoms vibrate more intensively than internal atoms.
Is there a doctor of chocolate in the house? Cambridge Univ. in England is seeking a doctoral student to pursue what sounds like the sweetest job in the world: studying the fundamentals of chocolate.
Laser physicists have found a way to make atomic force microscope probes 20 times more sensitive and capable of detecting forces as small as the weight of an individual virus.
Researchers are proposing that the Higgs boson may be responsible for the mode of inflation and shape of the Universe shortly after the Big Bang.
Your next commuter car could have two seats, three wheels and get 84 miles to the gallon. Elio Motors wants to revolutionize U.S. roads with its tiny car, which is the same length as a Honda Fit but half the weight. With a starting price of $6,800, it's also less than half the cost.
The physical properties of the ultra-white scales on certain species of beetle could be used to make whiter paper, plastics and paints, while using far less material than is used in current manufacturing methods.
Through commands, autonomous devices arranged selves into vast, complex shapes in the first 1,000-robot flash mob.
A student team has designed, built and tested a critical part of a new rocket engine as part of a NASA project to develop spacecraft technologies needed to land on the moon, Mars and other cosmic venues.
Researchers have made a novel discovery that may potentially protect the world from future collisions with asteroids. The team studied near-Earth asteroid 1950 DA and discovered that the body, which rotates so quickly it defies gravity, is held together by cohesive forces, called van der Waals, never before detected on an asteroid.
Scientists have discovered a new method to efficiently generate and control currents based on the magnetic nature of electrons in semi-conducting materials, offering a radical way to develop a new generation of electronic devices.
Physicists have created a tractor beam on water, providing a radical new technique that could confine oil spills, manipulate floating objects or explain rips at the beach.
Spintronics is a new field of electronics, using electron spin rather than motion. This technology requires insulating components that can control this quantum property. Scientists have shown experimentally that a novel material shows all the required properties.
Can shorter peach and nectarine trees reduce labor costs without sacrificing fruit quality and yield? According to researchers, eliminating ladders for stone-fruit farmers could cut labor costs by 50 percent or more and improve worker safety.
Scientists have made the first direct observations of free-electron Landau states— a form of quantized states that electrons adopt when moving through a magnetic field— and found that the internal rotational dynamics of quantum electrons is surprisingly different from the classical model.
Sound effects and visual effects have long been standard tools for entertaining audiences, but even as storytellers increasingly turn to haptic feedback to engage the sense of touch in games, theme park rides and movies, they have lacked a common vocabulary to describe or access these "feel effects." Now, researchers are beginning to fill that gap.
Chow mein on Mars? Moo shu on the moon? What would it be like to stir-fry in space? A bit messy, according to researchers, who recently conducted the first partial gravity cooking on record.
Researchers are using Wi-Fi to look through solid walls and see every square inch of what’s on the other side. Built into robots, the technology has far-reaching possibilities.
In what may be the birth of cheap, easy-to-make robots, researchers have created complex machines that transform themselves from little more than a sheet of paper and plastic into walking automatons.
Researchers have developed a laser-timing system that could allow scientists to take snapshots of electrons zipping around atoms and molecules. Taking timing to this new extreme of speed and accuracy will make it possible to see the formative stages of chemical reactions.
New techniques inspired by nature for accelerated aging and chemical extraction of mineral ores may lead to cheaper, safer and greener manufacturing processes.
A team of scientists has developed an entirely non-invasive technique that provides a view of blood flow in the brain. The tool could provide powerful insights into strokes and possibly Alzheimer's disease.
Engineers have fabricated a new elastic material coated with microscopic, hair like structures that tilt in response to a magnetic field. Depending on the field’s orientation, the micro-hairs can tilt to form a path through which fluid can flow.
Counterfeit drugs, which at best contain wrong doses and at worst are toxic, are thought to kill more than 700,000 people per year. To fight back against these and other forms of counterfeiting, researchers have developed a way to make labels that change when you breathe on them, revealing a hidden image.
A hybrid form of perovskite— which has recently been found to make highly efficient solar cells that could one day replace silicon— has been used to make low-cost, easily manufactured LEDs, potentially opening up a wide range of commercial applications in the future, such as flexible color displays.
