Every once in a while, someone creates something so incredible that it probably wouldn’t even pass the Hollywood standard, being deemed to unrealistic.
Scientists working at the Paul Scherrer Institute (PSI) have created a very specific type of material from over 1 billion magnets placed in a specific configuration. Astonishingly, its magnetic properties now change with temperature, just like water can be liquid, solid and gaseous based on temperature.
Nanoengineers from the San Diego University of California used innovative, self-developed 3D printing methods to create multipurpose, fish-shaped microbots – that they call microfish – which can swim around efficiently through liquids, powered by hydrogen peroxide and are magnetically controlled.
A research group has come up with an innovative way of dealing with blood clots through nanotechnology. This technology has the potential to save many lives every year, as blood clots are often associated with life-threatening events.
In what can only be heralded as a major breakthrough, a group at Arizona State University reports the demonstration of the first ever white laser – a laser that emits light over the full spectrum of visible colors. Up until now, lasers were designed to emit a distinct spectrum, either red, green, blue and so on. Combining multiple colors has always proved challenging and previous attempts had been slumped with shortcoming. This latest version seems to work wonderfully. If this technology can and will be scaled commercially, it could radically transform the industry. Its contrast and lighting capabilities, watt per watt, are well over LEDs and, moreover, it could help devise a new generation of Wi-Fi, called Li-Fi, which works on laser light and is 10 times faster.
Scientists have created a mixture of oil and fluorescent dyes that can be safely added to human cells – the dye then gets activated by short pulses of light and starts behaving like a laser, communicating the tissue’s position to doctors. The technology could add new ways for light to be used in diagnosis and treatment medicine. The system was devised
By now, we’ve all hopefully at least heard of graphene, the new wonder material that promises to revolutionize a swarm of applications. But now, a team of researchers from Finland have predicted the existence of atomically thin, free-standing 2D liquid phase – a liquid analogue of graphene.
In a world where in only a few decades we moved from clunky phones to wireless satellite-connected devices that allow you to be anywhere and do anything on the internet, it seems only normal that scientists will take it to the next level – to your brain. Already tested on mice, this fine mesh fits inside a syringe and unfurls on the brain to monitor its activity.
Microscopic swirls from gold might be the key to protect your cash and credit cards in the future, making identity theft virtually impossible. Researchers at Vanderbilt University developed the “Archimedes spirals” and report that they produce four times more blue light per unit volume than currently existing frequency amplifiers; they could be printed on currency, ID cards and pretty much everything that’s important to prevent counterfeiting.
It’s common sense – in order to brush your teeth, you need water, a toothbrush, and toothpaste. Well, a company from Japan wants to change all that: they’ve developed a nanotechnology toothbrush that basically eliminates the need for toothpaste.
