    Scientists have observed, quantified and created a new theoretical model of the coupling of 2 forms of collective atomic excitation, known as magnons and phonons in crystals of the antiferromagnet manganite (Y,Lu)MnO3, a mineral made of manganese oxide and rare-earth elements called yttrium (Y) and lutetium (Lu). This study could provide an important breakthrough for solving a 100 year old physical problem, and deepen our knowledge of multiferroics.

    While we generally think of solids as static objects, their molecules are actually in a constant state of vibration...

    Researchers have developed a low-cost, portable laboratory on a smartphone that can analyze several samples at once to catch a cancer biomarker, producing lab quality results. At a time when patients and medical professionals expect always faster results, researchers are trying to translate biodetection technologies used in laboratories to the field and clinic, so patients can get nearly instant diagnoses in a physician’s office, ambulance or emergency room.

    The WSU research team created an 8 channel smartphone spectrometer that can detect human interleu...

    Physicists have successfully employed a powerful technique for studying electrons generated through singlet fission, a process which it is believed will be key to more efficient solar energy production in years to come. Their approach, reported in the journal Nature Physics, employed lasers, microwave radiation and magnetic fields to analyse the spin of excitons, which are energetically excited particles formed in molecular systems.

    These are generated as a result of singlet fission, a process that researchers around the world are try...
