Researchers have developed a new fabrication method that makes tiny, thin-film electronic circuits peelable from a surface. The technique not only eliminates several manufacturing steps and the associated costs, but also allows any object to sense its environment or be controlled through the application of a high-tech sticker.
SPHERE, a planet-hunting instrument on ESO's Very Large Telescope, has captured the first confirmed image of a planet caught in the act of forming in the dusty disc surrounding a young star. The young planet is carving a path through the primordial disc of gas and dust around the very young star PDS 70. The data suggest that the planet's atmosphere is cloudy.
Twelve new moons orbiting Jupiter have been found -- 11 'normal' outer moons, and one that they're calling an 'oddball.' Astronomers first spotted the moons in the spring of 2017 while they were looking for very distant solar system objects as part of the hunt for a possible massive planet far beyond Pluto.
A new planet has been imaged, and it appears nearly identical to one of the best studied gas-giant planets. But this doppelganger differs in one very important way: Its origin. One object has long been known: the 13-Jupiter-mass planet beta Pictoris b, one of the first planets discovered by direct imaging, back in 2009. The new object, dubbed 2MASS 0249 c, has the same mass, brightness, and spectrum as beta Pictoris b.
Your torso is tuitive -- and more precise -- than joysticks for piloting drones, both simulated and real, according to a recent study. Work is already underway to implement this new body-machine-interface technology for search and rescue with drones.
Scientists have designed a range of nanostructures resembling marine diatoms -- tiny unicellular creatures. To achieve this, they borrow techniques used by naturally-occurring diatoms to deposit layers of silica -- the primary constituent in glass -- in order to grow their intricate shells. Using a technique known as DNA origami, the group designed nanoscale platforms of various shapes to which particles of silica, drawn by electrical charge, could stick.
Researchers have developed a prototype of a robot that can express 'emotions' through changes in its outer surface. The robot's skin covers a grid of texture units whose shapes change based on the robot's feelings.
Infrared cameras are the heat-sensing eyes that help drones find their targets even in the dead of night or through heavy fog. Hiding from such detectors could become much easier, thanks to a new cloaking material that renders objects -- and people -- practically invisible.
Nanokirigami has taken off as a field of research in the last few years; the approach is based on the ancient arts of origami (making 3-D shapes by folding paper) and kirigami (which allows cutting as well as folding) but applied to flat materials at the nanoscale, measured in billionths of a meter.
Particle physicists have discovered an extremely rare process that can be compared to tiny lightsabers. The researchers have shown that messenger particles of the so-called weak interaction interact with each other in a scattering process.
For decades, scientists hoping to understand how the retina interprets visual input have often had to resort to invasive techniques to dissect the retina from the animal in an effort to record the cells' activity, but a new system could make it possible to track the firing patterns of dozens of cells chronically in awake animals.
As demonstrated in a series of new studies, researchers show that as the prevalence of a problem is reduced, humans are naturally inclined to redefine the problem itself. The result is that as a problem becomes smaller, people's conceptualizations of that problem become larger, which can lead them to miss the fact that they've solved it.
Mars is experiencing an estimated 15.8-million-square-mile dust storm, roughly the size of North and South America. This storm may not be good news for the NASA solar-powered Opportunity rover, but one professor sees this as a chance to learn more about Martian weather.
Many animals use vocalizations to judge one another's size and physical formidability when in competition for mates or other resources. Now, researchers have found that humans can use nonverbal vocal cues, including aggressive roars, in a similar way.
Researchers and engineers have long sought ways to conceal objects by manipulating how light interacts with them. A new study offers the first demonstration of invisibility cloaking based on the manipulation of the frequency (color) of light waves as they pass through an object, a fundamentally new approach that overcomes critical shortcomings of existing cloaking technologies.
Similar to humans, non-human primates combine gestures, facial expressions, and vocalizations in various ways to communicate effectively. Researchers investigated one such signal, the 'leaf clip' gesture, which re-emerged in a wild chimpanzee group during an alpha takeover.
For a Galápagos penguin, beak size is nearly a perfect indicator of whether a bird is male or female, scientists have discovered. Armed with this knowledge, researchers could determine the sex of a bird quickly and accurately in the wild without taking a blood sample -- speeding up field studies of this unusual and endangered seabird.
