Scientists at the Swiss Nanoscience Institute and the Department of Physics at the University of Basel have developed a new method that has enabled them to image magnetic fields on the nanometer scale at temperatures close to absolute zero for the first time. They used spins in special diamonds as quantum sensors in a new kind of microscope to generate images of magnetic fields in superconductors with unrivalled precision

Requirements AtMega 16 IC/development board 3-Axis accelerometer LCD screen 16X2 (for displaying X, Y and Z data) Description This project makes use of three out of the eight ADCs present in AtMega16 IC to display the corresponding digital data of X, Y and Z outputs of an accelerometer on 16X2 LCD. Accelerometer First let’s talk […]

atmega32 avr based Drone Quadricopter:IntroductionOur project is a novel hand held controller in which we use an accelerometer to wirelessly control the motion of a Parrot AR Drone Quadricopter.Rationale:The main idea of our project was building a cool glove controller for a flying platform, a quadrotor in this case, which would give the user a […]

The circuit presented here demonstrates how to generate Audible Frequency from an AVR Microcontroller. The output of Microcontroller is always digital so to generate audible sound at the outset first it needs to be converted into Analog. A DAC (Digital to Analog Converter) is used for this purpose. Microcontroller generates sine wave of Audible Frequency […]

The Earth’s climate has been warming, but even though the Greenland ice sheet is melting rapidly in the coastal regions, there are large parts of the ice sheet (40 percent) where there has hardly been any melting on the surface. A warmer climate usually also means that there is more precipitation, but there has been no increase in the amount of precipitation on the ice sheet.

In a paper to be published today in the journal Science Advances, lead author Karen Meech of the University of Hawai`i’s Institute for Astronomy and her colleagues conclude that C/2014 S3 (PANSTARRS) formed in the inner Solar System at the same time as the Earth itself, but was ejected at a very early stage.

(Phys.org)—It might be said that the most difficult part of building a quantum computer is not figuring out how to make it compute, but rather finding a way to deal with all of the errors that it inevitably makes. Errors arise because of the constant interaction between the qubits and their environment, which can result in photon loss, which in turn causes the qubits to randomly flip to an incorrect state.

Twisted-winged parasites of the species Stylops ovinae reproduce using so-called traumatic insemination. Entomologists of the Friedrich Schiller University Jena and the Christian Albrechts University of Kiel published on this phenomenon in the new edition of the science magazine Scientific Reports

(Phys.org)—An international team of researchers has revealed for the first time, the structure of an enzyme that pathogenic bacteria use to reduce oxygen. In their paper published in the journal Science, the team describes their study of the atomic structure of a bd oxidase from the bacteria Geobacillus thermodenitrificans, and why they believe what they found might help to create new ways to combat bacterial infections
