With the delta variant of Covid-19 surging in many countries - e.g., over 100,000 new cases per day foreseen in the UK in the next few days, and many other countries following suit - we may feel depressed at the thought that this pandemic is going to stay with us for a lot longer than some originally foresaw.
In truth, if you could sort out your sources well, you would have predicted this a long time ago: epidemiologists had in fact foreseen that there would continue to be waves of contagions, although at some point mitigated by the vaccination campaigns. However, so much misinformation and falsehood on the topic has been since dumped on all media, and in particular on the internet, that it is easy to pick up wrong information.

Covid experts around the world respond to the UK’s decision to lift remaining restrictions on July 19 in an emergency online summit.

They say no public health officer would recognize this as a strategy.

An unknown methane-producing process is likely at work in the hidden ocean beneath the icy shell of Saturn's moon Enceladus, suggests a new study published in Nature Astronomy by scientists at the University of Arizona and Paris Sciences&Lettres University.

There is a belief that Airbnb listings cause increased crime in residential neighborhoods - or at least annoying late-night parties which increase risk of crimes. However, a new paper suggests that while Airbnb listings can be linked to a reduction in the local social dynamics that prevent crime, it isn't the tourists committing the crimes. And it takes years, which means Airbnb listings may be a symptom rather than the cause.
A new paper has statistically linked inflammatory bowel disease, an umbrella term for chronic inflammation of the digestive tract, to processed foods. But because every food is processed - no one eats wheat that hasn't been milled - the term has now become "ultra-processed."

On July 15 971, the bones of St Swithin were removed from their resting place on the order of Aethelwold, Bishop of Winchester, and placed in a shrine inside the cathedral. The saint, it seemed, did not approve. A violent storm followed, and rain fell for 40 days. And from that story came the belief that the weather on July 15 predicted a summer of sun or rain.

St Swithin’s day if thou dost rain’
For forty days it will remain;
St Swithin’s day if thou be fair,
For forty days will rain na mair.

Following my strong belief that science dissemination, and open borders science, is too important to pursue as a goal to constrain it by fears of being stripped of good ideas and scooped by fast competitors, I am offering here some ideas on a reserch plan I am going to follow in the coming months.

The benefits of sharing thoughts early on is evident: you may, by reading about them below, be struck with a good idea which may further improve my plan, and decide to share it with me; you might become a collaborator - which would add to the personpower devoted to the research. You might point out problems, issues to address, or mention that some or all of the research has already been done by somebody else, and published - which would save me a lot of time!
Raw food, from milk to meat, can obviously bring higher risk of bacteria. The raw milk fad in the US creates risk of illness orders of magnitude higher than milk that has been pasteurized to remove harmful bacteria.

In Europe, the 'raw' dog food fad may be creating something even worse; multidrug-resistant bacteria identical to those found in hospital patients. Drug-resistant infections kill an estimated 700,000 people a year globally and, with the figure projected to rise to 10 million by 2050 if no action is taken, the World Health Organisation (WHO) classes antibiotic resistance as one of the greatest public health threats facing humanity. 
Like coronavirus, Hepatitis C was only discovered as unique a few decades ago, but in that time science took its 2 million new HCV infections every year, with an estimated 70 million carriers of the virus globally, and 400,000 deaths annually to finding a cure. 

Directly acting antivirals (DAAs) can now stop it and therefore prevent the liver cirrhosis and liver cancer that can develop. Next up, said Professor Sir Michael Houghton at the European Society of Clinical Microbiology and Infectious Diseases, who won the Nobel Prize for Medicine and Physiology along with three other scientists for discovering it was distinct in 1989, is a vaccine.
Two approaches in development may lead to an inhalable COVID-19 vaccine that is scalable and can be transported and stored at room temperature.

They'll be too late to help with the actual COVID-19 but since coronavirus constantly mutates, like the flu, and 2019 was the third coronavirus pandemic in the last 17 years, it could be valuable for the next iteration.

One strategy employs modified bacteriophage particles that can be inhaled to deliver protection via the lungs to the immune system. The other delivers injectable adeno-associated virus-phage particles that directly encode protection against the virus in immune cells. They're only in rodents so far but they produced antibodies.
