The absence of electrical resistance exhibited by superconducting materials would have enormous potential for applications if it existed at ambient temperature and pressure conditions. Despite decades of intense research efforts, such a state has yet to be realized1,2. At ambient pressures, cuprates are the material class exhibiting superconductivity to the highest critical superconducting transit

Catching the coronavirus from surfaces is rare. The World Health Organization and national public-health agencies need to clarify their advice.

The coronavirus SARS-CoV-2 is transmitted predominantly through the air — by people talking and breat

The global pandemic of SARS-CoV-2 has now claimed millions of lives across the world. There has been an increased focus by the scientific and medical community on the effects of mild-to-moderate COVID-19 in the longer term. There is strong evidence for brain-related pathologies, some of which could be a consequence of viral neurotropism1,2,14 or virus-induced neuroinflammation3,4,5,15, including t
