Scientists at the Lawrence Livermore National Laboratory believe that dark matter may be composed of electrically charged particles that are bound by a yet-unknown force and have somehow managed to escape detection. The theory could be verified with the help of the Large Hadron Collider particle accelerator.
Today's simple metal lightning rods may be on their way to obsolescence. That's because scientists at The Hebrew University of Jerusalem are developing a high-tech alternative that could potentially reach higher and be more effective – laser lightning rods.
It seems as if the age of the bench-top breakthrough in rocket science is not a thing of the past. Dr Patrick Neumann of the University of Sydney has developed a new ion drive as part of his PhD thesis that is claimed to outperform the best one devised by NASA. According to Neumann, his new drive, which is still in the experimental stage, is more efficient than the latest High Power Electric Propulsion (HiPEP) ion engine and holds the promise of "Mars and back on a tank of fuel."
The largest "tree of life" ever created has been released, spanning 3.5 billion years and 2.3 million species. The work was not carried out from scratch, as such an effort would consume a vast amount of man-hours. Instead the researchers compiled data from almost 500 existing smaller trees displaying the divergence and evolution of life as we understand it.
A new record distance has been set for the quantum teleportation of information over optical fibers. Researchers working at the National Institute of Standards and Technology (NIST) claim to have transmitted the quantum information carried in light particles over 100 km, four times farther than previously achieved.
Do you remember Pig-Pen, the Peanuts comic character who's always surrounded by a cloud of his own filth? Well, it turns out that we're actually all a little like him. Scientists have discovered that not only does everyone emit an invisible "microbial cloud," but that individuals can be recognized by the bacteria that make up their particular cloud.
Getting a flat tire might never be an entirely hassle-free experience, but before too long it may no longer be necessary to patch or replace punctured tires. Instead, thanks to research currently being conducted in Europe, damaged tires could just be left a few hours to heal on their own.
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
