Scientists at UC Berkeley have developed a foldable, incredibly thin invisibility cloak that can wrap around microscopic objects of any shape and make them undetectable in the visible spectrum. In its current form, the technology could be useful in optical computing or in shrouding secret microelectronic components from prying eyes, but according to the researchers involved, it could also be scaled up in size with relative ease.
Although barcodes are currently utilized mainly to keep track of
merchandise, they may soon also be used to detect counterfeit goods.
We're not talking about ordinary barcode labels, however. Instead,
British scientists at Sofmat Ltd and the University of Bradford have
devised a new 3D barcode that's actually molded into plastic or
Currently, when scientists want to know if bacteria are present in
water, they have two main choices. They can take a sample to the lab,
where they'll try growing the suspected bacteria in it, and then count
the number of resulting colonies to determine the concentration. Or,
they can analyze it using expensive lab-based gas chromatography or mass
spectrometry equipment. Now, however, researchers from Seoul National
University have developed a "bioelectronic nose" that could be used on
location, and that is reportedly more sensitive than existing
Sunlight can be used to generate electricity either through a
photovoltaic effect, or by harnessing the heat produced by the light.
There are already hybrid systems that combine both, but scientists at
Korea's Yonsei University have now developed a type of hybrid setup that
they claim works better.
One of the challenges facing designers of traditional flat solar panels
is the fact that the sun doesn't conveniently stay in one place. This
means that in order for a panel to receive as much sunlight as possible,
it has to pan with the sun as it moves across the sky. While
there are motorized assemblies designed to do just that, they add
complexity, weight and expense to photovoltaic systems. Now, however,
University of Michigan scientists have developed a simpler alternative –
and it's based on the ancient Japanese cut-paper art of kirigami.
From military shelters and solar arrays to batteries and drones, engineers continue to prove that origami can be the inspiration for more than just paper cranes. The latest creation inspired by the ancient art of paper folding is a new "zippered tube" design that forms paper structures with enough stiffness to support weight, but can be folded flat for shipping or storage. The scaleable technique could be used in anything from microscopic robots and biomedical devices, to buildings and bridges.
A recent study carried out by MIT has characterized the cleansing effect that raindrops have on our atmosphere in removing aerosol and other pollutants from the air. The results of the research could be instrumental in creating reliable forecasts for air quality, and creating more accurate models of climate change impact due to clouds.
It may not instantly whisk you to far-flung reaches of the universe like the gravitational wormholes of Stargate, Star Trek and Interstellar, but researchers at Universitat Autònoma de Barcelona (UAB) claim to have created the first experimental wormhole that links two regions of space magnetically.
