“The sense of smell in Covid-19 patients appears to be lost, because the sustentacular cells assist neurons in sensing odours, probably by processing odour-binding proteins,” Butowt said.

Studies over the years have sought to quantify the infection risk. Here, we look at two recent ones — neither study, however, looks specifically at the coronavirus pandemic.

A new concern has emerged around pregnant women who have Covid-19 — damaged placentas.

One antibody, called S309, taken from a SARS survivor from 2003, has been shown in the lab to neutralise SARS-CoV-2. The results were reported in Nature this week.

A group of molecules that should be fighting the virus are diminished with age and chronic health problems, researchers report in the journal Aging and Disease.

Meet Troglomyces twitteri, a fungus spotted on a Twitter image by a Denmark biologist. What is this species, and what is its relationship with millipedes?

How many lives have been saved as a result of reduced pollution? Here's what a new study has found in China.

The fact that cats can get infected by the coronavirus has been known for some time now; what do the latest findings add to existing knowledge?

From her stress on handwashing to the use of data to assess healthcare outcomes, the battle against the pandemic is a constant reminder of her work. Yet the same pandemic threatens to shut down a museum dedicated to her.

Researchers in France have put forward a hypothesis that the presence of nicotine actually equips the body to fight COVID-19.

Remdesivir is designed to obstruct the stage of replication, when the virus creates copies of itself, followed endlessly by the copies creating copies of themselves.

Researchers have reported that they have determined the 3D structure of this “copy machine”. This makes it possible to investigate how drugs such as remdesivir work, they note.

A study has examined the ability of various materials to keep out respiratory particles — and by extension the novel coronavirus — and identified a combination of two fabrics as possibly the best: either cotton plus natural silk, or cotton plus chiffon.

The new study has identified the specific cells where the mechanism of entry most likely comes into play when the virus begins it attack.

John Horton Conway will be best remembered for the “Game of Life”, which he invented around 1970 and which continues, 50 years later, to fascinate people, including many who are not mathematicians.

It is still a ‘novel’ coronavirus that causes COVID-19, but the emerging picture has given researchers clues about how to target it. A look at its structure, how it infects, and the behaviours scientists hope to block

Coronavirus: Several lions and tigers at the Bronx zoo in New York, in fact, have shown symptoms of respiratory illness.

It has long been known that Earth’s spin has slowed over time. A new study looks at daily and annual variations in the mollusc shell.

It is dedicated to pi, whose value up to five decimal places is 3.14159. The idea originated in the United States, where the convention is to write dates in a format that expresses March 14 as 3/14.
