“From prow to stern, this little boat measures 30 micrometers, about a third of the thickness of a hair. It has been 3D-printed by Leiden physicists Rachel Doherty, Daniela Kraft and colleagues. The image was made using an electron microscope …
“Chameleons can famously change their colors to camouflage themselves, communicate and regulate their temperature. Scientists have tried to replicate these color-changing properties for stealth technologies, anti-counterfeiting measures and electronic displays, but the materials have limitations. Now, researchers have developed a …
“The digital data generated around the world every year is now counted in zettabytes, or trillions of billions of bytes - equivalent to delivering data for hundreds of millions of books every second. The amount of data generated continues to grow …
“Nanophotonics researchers demonstrate ultrafast polarization switching U.S. and Italian engineers have demonstrated the first nanophotonic platform capable of manipulating polarized light 1 trillion times per second. “Polarized light can be used to encode bits of information, and we’ve …
“Researchers have designed a skin-like device that can measure small facial movements in patients who have lost the ability to speak. People with amyotrophic lateral sclerosis (ALS) suffer from a gradual decline in their ability to control their muscles. As …
“Ubuntu was, is, and will probably remain the leading Linux distribution out there, at least as far as the number of users is considered. And the one to thank is Canonical’s commitment to keeping Ubuntu up-to-date with the latest …
“Researchers develop an efficient, low-energy method for upcycling polyethylene plastic waste into valuable molecules that can be repurposed for further use When we started using plastics about 70 years ago, not much thought — if any — was given to the implications …
“In case of an emergency, first responders like the fire brigade need up-to-date information. 2D maps are a common source of information but they can be difficult to read in an emergency situation. UT PhD-student Shayan Nikoohemat created an algorithm …
“Scientists at the University of Wisconsin–Madison have discovered a way to control the growth of twisting, microscopic spirals of materials just one atom thick. The continuously twisting stacks of two-dimensional materials built by a team led by UW–Madison …
“What do Albert Einstein, the Global Positioning System (GPS), and a pair of stars 200,000 trillion miles from Earth have in common? The answer is an effect from Einstein’s General Theory of Relativity called the “gravitational redshift,” where …
