Deep diving the new coronavirus strain and mutation N501Y

A new and more infectious strain of the novel SARS-CoV-2 virus has been detected in England over the past week. By infectious, the virus is spreading far more easily although the new strain does appear to produce worst symptoms.

Op-Ed: Tattoos and skin damage: Looking at the data

Tattoos are increasingly popular and tattoo parlours are one area of consumer product supply that are doing well during the peculiar circumstances arising from COVID-19. Not all tattoo shops are of the same standard and there are some areas of concern.

How best to assess for coronavirus: Wastewater or surfaces?

While there has been considerable interest concerning the spread of coronavirus by wastewater and using this method to track community spread, a new study puts across the view that surfaces provide a better indicator of viral spread.

Essential Science: What coronavirus mutations mean for vaccines?

This week's column looks at mutations, both the issue that has hit the news about minks and cross-infection to humans, and a predominant mutation within the US and Europe. The presence of the mutation may help to develop an effective vaccine.

Q&A: Using faster diagnostics to treat COVID-19 patients Special

COVID-19 patients are increasingly susceptible to co-infections such as pneumonia and Staphylococcus - many of which display similar symptoms to COVID-19. What are the options for patients and can new diagnostics help?

Government of Canada supports phase 1 trial for COVID-19 vaccine

Providence Therapeutics, a Canadian biotechnology company, has announced that the federal government of Canada will support its Phase 1 Clinical trials for a COVID-19 vaccine. This is an important step in the fight against the coronavirus.

Essential Science: Why masks work and time to end the debate?

How effective are face masks? The body of evidence in favour of masks continues to grow. In this week’s Essential Science, we consider a diverse array of different literature that looks at mask wearing in different contexts.

Op-Ed: A herd immunity policy? The risks remain considerable

As part of the efforts to combat coronavirus discussion around ‘herd immunity’ periodically arises. What does this mean exactly and why is the majority of scientific and political opinion against such a strategy?

Does catching the common cold make COVID-19 less severe

Early stages of research suggest that being infected previously with a different type of coronavirus to SARS-CoV-2 (which causes COVID-190, such as the common cold, may lessen the severity of the infectious virus.

Essential Science: New treatment for the most neglected disease?

Schistosomiasis (or bilharzia) is a neglected tropical disease, and the one that causes significant ill-health effects to millions of people. The disease is caused by a parasitic worm.

Travel was a major factor with coronavirus spread

The extent to which coronavirus spread was based on the type and speed of the interventions taken. In many cases, such interventions were effective. However, key networks were also responsible for the viral spread.

An autumn 'Twindemic'? When flu and COVID-19 collide

Medics are generally sharing a concern about how the upcoming influenza season could impact the ongoing COVID-19 pandemic, especially the severity of infections should an individual contract both viruses.

Face masks stop droplets, but many face coverings are ineffective

A new model demonstrates visually how face masks are effective in lowering droplet emissions, and hence minimizing viral particles, during normal wear. The N95 masks without valves comes out as the most effective item of personal protective clothing.

Deep-dive into the underlying risk factors and COVID-19 symptoms

Researchers have analysed the pseudonymised health data of over 17.4 million U.K. adults to discover the key factors associated with death from COVID-19.

Uncertainty remains over environmental spread of coronavirus

How easily does coronavirus spread between individuals in a household? Is the main mechanism by air or by surfaces? Despite a new study, the answers remain unclear.

Tackling the bacterium that causes cat scratch disease

Researchers have gained a new insight about a protein named BafA which stimulates the production of new blood vessels that support bacterial lesions. This discovery may help develop new methods for diagnosing and treating bartonellosis.

Early adoption of face masks led to lower COVID-19 rates

A new study finds that those countries that were early adopters of mandatory face mask wearing in public saw lower COVID-19 rates compared with nations that put policies in place later, or which have not mandated masks at all.

COVID-19: Why surfaces still present a contamination vector

This week has seen some interesting COVID-19 related research published. This includes an association with surfaces from a hospital outbreak and a new project to look at how easily the virus can be tracked through testing samples of wastewater.

COVID-19 employment related lawsuits have begun

It was perhaps inevitable that COVID-19 would start to spill over into employee relations and employment law. Legal trends suggest that employer-related litigation in relation to the viral pandemic is starting to rise.

Each virus-hit person infecting fewer than one other in Germany: data

Berlin - Each coronavirus-infected person in Germany is infecting fewer than one other person, closely watched data showed, as Europe's biggest economy looks to ease curbs to halt contagion from Monday.

Tracking viral epidemics needs to account for evolution

Models for tracking viral outbreaks, as with the current novel coronavirus issue, need to assess the ability of the virus to mutate. Accounting for the evolutionary impact of the virus is essential for accurate modelling, according to new research.

Why the fight against coronavirus is proving so complicated

Many in society are wondering why the novel coronavirus is proving especially challenging to contain. There are several reasons for this complexity, ranging from how infectious it actually is to how it moves through a population.

Artificial intelligence finds new antibiotic

Technologists, working with microbiologists, have made a significant breakthrough in the hunt for new antimicrobials. By using artificial intelligence, a new candidate antibiotic has been identified.

Op-Ed: Myth-busting: The worst of the coronavirus falsehoods

The global preoccupation with the coronavirus pandemic is, unfortunately, leading to a plethora of fake news stories geared around attempts at self-protection and cures. Some are due to ignorance, others more malicious. We look at a few of these.

Bacteria-eating viruses bridge the gap of life and non-life

Bacteriophage are a type of simple virus that infects bacteria, being spread by its bacterial host and being reliant upon the bacterial cell to replicate. New research indicates that some phages are more complex than they first appear.

Why does the flu virus affect some people worse than others?

Influenza affects all people once they become infected. However, the severity of the effects and how long the effects of the virus last for vary between different people. Virologists have been looking into this and now have an answer.

Scientists explore why bat viruses are so deadly

The coronavirus Covid-19, which has been making global headlines is a zoonotic virus (one thought to have transferred from animal to human). The primary source could be from bats. Scientists are looking at what makes bat viruses so deadly.

New model to estimate spread of the novel coronavirus

A new modeling study has been used to estimate the spread of the 2019 novel coronavirus (2019-nCoV). The model reveals that up to 75,800 individuals in the Chinese city of Wuhan may have been infected to date.

Essential Science: Biosignatures detect early symptoms of TB

Researchers have developed an advanced method for the detection of biosignature, paving the way for the early detection of tuberculosis. The method allows for TB to be detected in patients, months before symptoms appear.

Is airplane sewage spreading antibiotic-resistant microbes?

Examining sewage from five airports, microbiologists have found that 90 percent of 187 E. coli isolated were resistant to at least one antibiotic.
