New Zealand has effectively managed to eliminate the virus, butContinue Reading
A tetraquark. CERN, CC BY-SA The LHCb collaboration at CERN has announced the discovery of a new exotic particle: a so-called “tetraquark”. The paper by more than 800 authors is yet to be evaluated by other scientists in a process called “peer review”, but has been presented at a seminar.Continue Reading
It didn’t take long after the first cases of COVID-19 were reported for conspiracy theories to begin circulating that the virus was a secret ploy by pharmaceutical companies to sell a vaccine. Other false theories quickly emerged, including one suggesting Bill Gates is creating a tracking device to be implantedContinue Reading
