CORONAVIRUS RESEARCH HIGHLIGHTS: 1-MINUTE READS
Commuters and New York infection hotspots
Researchers compiled coronavirus test results from about 1,700 women who gave birth in New York City hospitals. The neighbourhoods that were home to more infected women correlate with those with the highest number of commuters over the past three months. Many of the commuters are probably ‘essential workers’, who should be protected to prevent the virus’s spread, the researchers say.

Risk for minority ethnic groups is a troubling mystery
People who are not white face a substantially higher risk of dying from COVID-19 than do white people — and pre-existing health conditions and socioeconomic factors explain only a small part of the higher risk. Researchers examined the medical records of more than 17 million people in England and found that there must be something more to the grim inequality than health conditions or social disadvantages.

Speedy technique churns out synthetic viruses
Researchers have used yeast cells to create a synthetic version of the SARS-CoV-2 genome in just a week — much more quickly than other methods. The technique could be used to assemble viruses rapidly to study the biological effects of new mutations, the researchers say.

Strong and sweeping antibody response to coronavirus
Nearly everyone who recovers from COVID-19 makes antibodies against the new coronavirus. A study of more than 1,300 people who had symptoms of the disease found that more than 99% of them eventually developed antibodies — though some didn’t produce detectable antibodies until one month after they first started feeling ill.

A separate study found that people infected by the new coronavirus make antibodies against several of the virus’s proteins. Much of the effort to develop vaccines and diagnostic tests has focused on a viral protein called Spike. But these results, which have not yet been peer-reviewed, suggest that other proteins might also be important determinants of immunity against SARS-CoV-2.
