Volunteers help find Star that exploded 970 million years ago, predating the dinosaurs

The left is the "new image" from a couple of nights ago while the middle one is the "reference" image taken a couple of years ago, the right image is the difference between "new" and "reference." The researchers said there is clearly an exploding star in the outskirts of the galaxy. Credit: ANU

Online volunteers, including a woman from Belgium and a Scottish man, have helped astronomers at The Australian National University (ANU) find a star that exploded 970 million years ago, predating the dinosaurs’ time on Earth. ANU has invited everyone with an interest in astronomy to join the University’s search for supernovae, which scientists can use to measure the Universe and acceleration of its growth.

Dr Brad Tucker said his team was ab...

Drugs already approved for other uses in people help frogs survive deadly E. coli by changing their cells’ electrical charge. Changing the natural electrical signaling that exists in cells outside the nervous system can improve resistance to life-threatening bacterial infections, according to new research from Tufts University biologists. The researchers found that administering drugs, including those already used in humans for other purposes, to make the cell interior more negatively charged strengthens tadpoles’innate immune response to E. coli infection and injury...

‘Drastically’ Higher Resolution to your TV and Smartphone

UCF Research Could Bring ‘Drastically’ Higher Resolution To Your Phone and TV

University of Central Florida Assistant Professor Debashis Chanda and physics PhD student Daniel Franklin have made a breakthrough that could produce much higher resolution for TVs, smartphones and other video screens.

Researchers at the University of Central Florida have developed a new color changing surface tunable through electrical voltage – a breakthrough that could lead to 3X the resolution for televisions, smartphones and other devices. With current technology, each of the pixels contain 3 subpixels – one red, one green, one blue. Assistant Professor Debashis Chanda and physics doctoral student Daniel Franklin have come up with a way to tune the color of these subpixels...

Magnetic Switch Turns Strange Quantum Property Berry Phase On and Off

These images show the orbital paths of electrons trapped within a circular region within graphene. In the classical orbit (top image), an electron that travels in a complete circuit has the same physical state as when it started on the path. However, when an applied magnetic field reaches a critical value, (bottom image), an electron completing a circuit has a different physical state its original one. The change is called a Berry phase, and the magnetic field acts as a switch to turn the Berry phase on. The result is that the electron is raised to a higher energy level.
