Forget holograms, here's a 'floating e-ink' display
The amount of pixels in a display has been the source of forum flamewars since the advent of HDTV, which makes an experimental display technology from the University of Sussex so interesting. It's called JOLED and it measures a whopping 7 x 6 voxels high and wide, respectively. Hold on, it gets more interesting. Each voxel is a diminutive multi-colored sphere, and they're suspended in mid-air by an array of ultrasound speakers that "create high-pitched and high-intensity soundwaves that are inaudible but forceful enough to hold the spheres in place," according to the school.
Study: we can ditch fossil fuels in 10 years, if we want to
The quest to end the use of fossil fuels might not be as daunting as you think. A University of Sussex study claims that humanity could drop coal and oil within a decade, based largely on historical evidence that many tend to overlook. Professor Benjamin Sovacool notes that energy transitions have happened quickly whenever there was a combination of "strong government intervention" with economic or environmental incentives to switch. It only took 11 years for the Canadian province of Ontario to abandon coal energy, for example, while nuclear power surged to 40 percent of France's electricity supply within 12 years. In the case of fossil fuels, it's a combination of climate change worries, dwindling resources and advanced technology that could step up the pace.
British scientists create a 'tractor beam' of ultrasonic sound
A team of researchers from the Universities of Bristol and Sussex have developed the world's first functioning sonic tractor beam able to operate outside of a lab environment. The device uses 64 miniature speakers to generate high-amplitude, ultrasonic sound waves. These waves create an "acoustic hologram" (read: force field) capable of moving pea-sized objects without physically touching them. Adjusting the output of individual speakers allows the researchers to move, rotate and hold items at will.
This box transmits emotions to your hand
This slightly unwieldy looking machine can apparently deliver emotions to your hand through "mid-air haptics", pinpointing areas on your palm that are attuned to certain emotions, and stimulating them. A study from the University Of Sussex used an Ultrahaptics system to communicate emotions between test groups, with the haptic group stating significantly higher stimulation compared to a test group that was only shown a picture. (Mere optical stimulation? Pssch.) Dr Marianna Obrist, Lecturer at the Department of Informatics, has apparently figured out that stimulating different areas of the hand conveys different things: hot bursts of air to the area around the thumb, index finger and middle part of the palm generate excitement, while sad feelings can be delivered by slow and moderate stimulation on the outer palm and areas around the little finger.
