A new study finds that unless you are suffering a life-threatening illness, the worst place to go if you want to avoid exposure to coronavirus is to a doctor. You instead should hope you have a "non-essential" job, just not so non-essential you don't get paid.

It's obvious that that those working in healthcare roles are at heightened risk of contracting SARS-CoV-2 and therefore COVID-19, but it has not been clear what the risks might be compared to those working in other sectors.

While a loud minority says there needs to be lockdowns for the foreseeable future, they are often government-funded workers whose jobs are secure - and they are not thinking about the mental health issues, including among children.

Social distancing and school closures are thought to have badly affected children's mental health but there has been little hard evidence to substantiate it, largely because of a lack of good baseline data for the same children collected before the first lockdowns in March. There was no reason. Everyone believed this would be three weeks, not a year or more as President-Elect Joe Biden is saying he intends to implement.

Have you ever answered a phone call from a stranger and had them introduce themselves and then ask how you are doing? Somewhere, someone created that tactic with the belief that it makes callers seem interested in your life but because you know they are not, it is probably annoying.

As medical care has improved, doctors are able to screen for cancer earlier than ever, and that is why cancer cases in young adults and adolescents are prevalent enough that they can be considered a distinct population.

Age remains the biggest factor for everything, of course, if you live long enough you are going to get cancer of some kind, it is built into our biology, but the increase in screening and therefore diagnoses means young adults can be considered distinct from pediatric and adult cancers and have their own middle ground for research.

Nearly all of the atoms that make up the our planet and us were forged in stars and the carbon most important to life as we know it was made by the triple-alpha process. The process starts with alpha particles, cores of helium atoms, with each alpha particle is made up of two protons and two neutrons. The triple alpha process is just what it sounds like; three alpha particles are fused inside a star, creating a new particle with six protons and six neutrons - the most common form of carbon in the universe - with a surplus of energy, a Hoyle state. That Hoyle state can split back into three alpha particles or relax to the ground state of stable carbon by releasing gamma rays.

Dolutegravir, the HIV wonder drug and current first-line treatment, is less effective in sub-Saharan Africa, and the reason is as old as evolution itself - mutation. 

As HIV copies itself and replicates, its genetic code (RNA) can change. While a drug may initially be able to suppress or even kill a virus, certain mutations can allow the virus to develop resistance to its effects. If a mutated strain begins to spread within a population, it can mean once-effective drugs are no longer able to treat people.
