Researchers build first permanent optical memory on a chip

Picture courtesy of Wikimedia CommonsA team of boffins has created the first permanent optical memory on a chip, a critical step towards photonic chips.

Harish Bhaskaran, a nanoengineering expert at the University of Oxford and electrical engineer Wolfram Pernice at the Karlsruhe Institute of Technology in Germany, have worked out a way to solve to the disappearing memory problem using material at the heart of rewritable CDs and DVDs.… Read the rest

Sodium ion batteries are commercially feasible

Screen Shot 2015-09-24 at 14.52.06The inventor of the lithium ion battery and a team of researchers at the University of Texas in Austin said they’ve identified a cathode material that could pave the way for low cost sodium ion batteries.

Professor John Goodenough, the inventor of the lithium ion battery, said that sodium ion batteries offer a promising replacement for lithium ion batteries because sodium is abundant and cheap.… Read the rest

Schrodinger’s cat gets its cheezburger

schrodingers_catBoffins have worked out a way of putting a bacterium into an uncertain state similar to that faced by Schrödinger’s cat

In Schrödinger’s 1935-thought experiment, a cat found itself in a closed box with a small radioactive source, a Geiger counter, a hammer and a small bottle of poison.  It would make the cat potentially dead or alive – and thus create two very hacked off moggies.… Read the rest

A Cambridge University report, published in the International Journal of Behavioural Nutrition and Physical Activity found that teens who spend an extra hour a day surfing the internet, watching TV or playing computer games risked performing two grades worse in exams than their peers who don’t.… Read the rest

Human magnetic field offers communication hope

Human magnetic field demoResearchers at the University of California San Diego believe they have hit on a method using the human body to allow communication between different wearable devices.

The electrical engineers showed off a wireless communication method that sends magnetic signals through the body which offers a better method of communicating than, for example, Bluetooth.… Read the rest
