The test uses a simple colour change to identity presence of the virus. A positive sample changes from pink to yellow. Each test uses three vials, each with different primers. A positive test would turn two vials yellow and leave one pink. This acts as a negative control to confirm the test is working. Image: University of Oxford. The team, led by Professor Zhanfeng Cui and Professor Wei Huang , have been working to improve test capabilities as the virus spreads internationally. The new test is much faster and does not need a complicated instrument.

What's New
The Standard Model of the fundamental particles describes the W and Z bosons as the mediator particles of the weak force, one of the four known fundamental forces responsible for the phenomenon of radioactivity and an essential ingredient to our Sun's thermonuclear process. W boson can decay into an electron, muon or tau, and the corresponding neutrino. The CMS collaboration has recently released the results of a brand-new search for "new physics" by combining three W bosons under its microscope. The W boson can be exploited as a probe either for precise Standard Model tests or new physics searches when undiscovered particles are searched for that decay to W bosons. For example, in June , the CMS collaboration has released the first observation of the simultaneous production of three W or Z bosons, a Standard Model process that appears 50 times more rarely than the production of the already very infrequently produced Higgs boson.
