Using nanometer-size metamaterials, researchers at Missouri University of Science and Technology have developed a technique to print images that uses the manipulation of light, rather than the application of ink, to produce colors. This "no-ink" printing method has been demonstrated by producing a Missouri S&T athletic logo just 50 micrometers wide.
A few months ago, we reported on the development of a material that uses the same technique employed by gecko feet to allow its adhesion to be turned on and off at will. This allows fragile components, like those used in the manufacture of semiconductors, to be carefully picked up and put down without suction or residue-leaving adhesives. Now researchers at the University of Pennsylvania (UPenn) have developed a gripper, also inspired by the gecko and also tunable, that they claim is much simpler, making it easy and cheap to mass produce.
Brimming with nutrients, antiooxidants and healthy fats, avocado –
otherwise known as nature's butter – carries a multitude of health
benefits inside its coarse, leathery skin. But new research is now
pointing to what could be its most valuable secret yet. A Canadian
scientist has discovered a lipid in avocado that could prove key to
battling leukemia by attacking the deadly disease at its core, namely
the highly resilient stem cells that drive the disease and make treating
it such a difficult task.
With a pivotal role in fending off infections and disease, white blood cells are the engine room of the body's immune system. But little was known about what happens exactly when these cells reach the end of their life cycles. Scientists have now captured the death of white blood cells on camera for the first time, showing that they eject much of their contents while decomposing. One reason for this could be to warn neighboring cells of dangerous pathogens in the area. The researchers say learning more about their expiration could help bring about improved health treatments in the future.
Researchers from the US Department of Energy's Argonne National Laboratory have created a new combination material from graphene and diamonds that's able to almost entirely overcome friction. The property, known as superlubricity, is highly sought after for its potential use in a wide range of mechanical systems.
PlanetiQ has begun testing its new Pyxis weather instrument. Pyxis tracks GPS signals traveling through the atmosphere and makes measurements based on their behavior. PlanetiQ says it can "dramatically improve weather forecasting, climate monitoring and space weather prediction."
Having previously used Wi-Fi signals to look through walls, a team of researchers in professor Yasamin Mostofi's lab at the University of California, Santa Barbara, has now turned the wireless signals to the task of counting the number of people walking in a particular area – even if they aren't carrying any Wi-Fi-enabled devices.
A new study by MIT has revealed that the quantities of nitrous oxide (N2O), otherwise known as laughing gas, being released by the world's oceans has been dramatically underestimated. Heightened levels of N2O have the potential to seriously influence the health of our planet's ozone layer, as the gas is around 300 times more potent than the more prevalent menace of carbon dioxide emissions.
While there are already plenty of apps that help birdwatchers identify
birds, most of them work by searching a database based on descriptions.
Cornell University and the Visipedia research project's Merlin Bird
Photo ID program, however, goes further – it utilizes computer vision
tech to identify birds pictured in user-supplied photos.
