Material scientists at Oxford University, collaborating with experts from Karlsruhe, Munster and Exeter, have developed the world’s first light-based memory banks that can store data permanently. The device is build from simple materials, in use in CDs and DVDs today, and promises to dramatically improve the speed of modern computing.

Killer AI? Let’s Solve the Smaller Problems First

Tesla Motors’ Elon Musk has said that our civilization is dangerously close to encountering AI problems within a “five-year timeframe, 10 years at most.” He made the comment on the website Edge.org shortly before deleting it. His point was that, sometime soon, we may actually create a form of artificial intelligence that decides to rise up and wipe out the

Lightpaper prints LEDs and ink on incredibly thin surfaces


When I first heard about 3-D printing, I was completely stoked. The whole concept blew me away and changed forever what I thought of ‘printing’. We now also know about machines that print metals, food and even human organs, why not light too? While not a 3D printer, Rohinni’s Lightpaper technology can be credited as innovative; once more lifting the margin and

Indian teenager invents cheap device that turns breath into speech

In photo: sixteen year old inventor Arsh Shah Dilbagi demonstrating his breath to voice synthesizer.

About 1.4% of the world’s population today is speech impaired, due to conditions such as Amyotrophic lateral sclerosis (ALS), locked-in syndrome (LIS), Encephalopathy (SEM),Parkinson’s disease, and paralysis. Imagine all the people living in Germany today were unable to speak and you’ll come to realize just how far reaching this condition is. So, aside for those being paralyzed, there are a lot

‘Herding’ cells with direct electric current may aid in tissue engineering

The top image shows a patch of epithelial cells. The white lines in the middle image mark the electric current flowing from positive to negative over the cells. The bottom image shows how the cells track the electric field, with blue indicating leftward migration and red signaling rightward movement (credit: Daniel Cohen)

The human body is littered with free ions and salts, which goes to explain why so much of our physiology is controlled by electrical signals, from neural pathways to muscle articulation. Very related, researchers at UC Berkeley have shown for the first time that direct current can be used to deliberately guide migration of a sheet of epithelial cells. Practically, the

Details of some 2000 volcanic eruptions that occurred in the past 1.8 million years are now available in a new open access database, complied by scientists at the University of Bristol with help from the UK, US, Colombia and Japan. Volcanic eruptions are among the most dangerous natural hazards, having the potential to take numerous lives, significantly impact climate, disrupt

NASA announced in a recent statement that they have beamed an image of the legendary painting to the Lunar Reconaissance Orbiter, a spacecraft currently orbiting the Moon, to test communication abilities with the satellite, using laser technology. The image was first converted to a suitable digital format, after which it traveled just less than 400.000 km to the satellite. “This

Transistor nanowires stacked in ‘4-D’ hint to future tech

rdue and Harvard universities. The transistor is made from tiny nanowires of a material called indium-gallium-arsenide, which could replace silicon within a decade. The image was taken with a transmission electron microscope (Purdue University image)

It’s amazing how this cross-section view on the right showcasing a  new type of transistor from  Purdue and Harvard universities resembles a Christmass tree, just in the nick of the time for the holiday season. Its design, however, has little to do with a Christmas trees. Make no mistake, the transistor’s shape and design follows a pattern that allows it to operate

New polymer coating technique leads to first-ever completely plastic solar cell and makes way for even thinner electronics

A team of researchers led by Georgia Tech's Bernard Kippelen has developed the first completely plastic solar cell, as seen captioned above exposed to humidity and oxygen. (Credit: Virginie Drujon-Kippelen)

One of the cutting edge technologies currently used today in manufacturing allows for printing materials directly onto a surface to create electrically functioning devices which are very thin and flexible. The best example of such an application are organic light-emitting diodes (OLEDs), widely used as displays for most new generation smartphones commercially available now. The process however is very tedious,

A novel technique cools electronic devices faster and cheaper


Researchers at  North Carolina State University have developed a new technique of cooling electronic devices which they claim and prove through their findings that it can lead to an increase of performance by improving the rate of heat exchange, while also lowering the cost of manufacturing. The scientists’ findings might lead to a new generation of more efficient heat sinks,
