With COVID-19 and worries about the SARS-CoV-2 virus keeping millions of people at home, activists and lawyers are hoping to resurrect worry about a problem dismissed by scientists as a money grab; third-hand smoke.

A new estimate says that of 378 metropolitan areas, many could actually exist on locally grown food - if the local area is up to 200 miles away, which means New York City could claim farms in Delaware, New Jersey, Pennsylvania, Rhode Island, Massachusetts, and Connecticut are local to New York. 

Even then, diets would have to change, because progress has meant having diversity and choice, and if locally-grown were really necessary, the population would starve along the Eastern Seaboard and the Southwest of the U.S. And meat would only be for the rich.

In the old days, if you wanted to spread desirable characteristics in livestock you had to try breeding and hope for the best. The 19th century breakthroughs in genetics promised a future where trial and error was no longer the norm.

Now, with desire to optimize food production and reduce environmental impact without harming choices for poor people, scientists have created pigs, goats and cattle that can serve as viable “surrogate sires” - male animals that produce sperm carrying only the genetic traits of donor animals.

While it is said that around six percent of voting Americans decide elections - the truly undecided - it is more the case that getting out the vote among your own party matters most. That is why political parties will drive their own to polling places while telling the other side the date of the election has been changed.

"Anti-scientific thinking" is a bad disease of our time, and one which may affect a wide range of human beings, from illiterate fanatics such as anti-vaxxers and religious fundamentalists on one side, to highly-educated and brilliant individuals on the other side. It is a sad realization to see how diversified and strong has become this general attitude of denying the usefulness of scientific progress and research, especially in a world where science is behind every good thing you use in your daily life, from the internet to your cell-phone, or from anti-cavity toothpaste to hadron therapy against tumours.

Are you excited about dozens of COVID-19 vaccine candidates? Do you get confused about whether or not it's as harmful to have been exposed to the 2019 SARS-CoV-2 coronavirus as it is to have COVID-19? Do you think the malaria drug hydroxychloroquine will either save you from COVID-19 or give you a heart attack?

If any of the above are true, you have been reading too much corporate media and witnessed coverage that they can claim is resulting from peer-reviewed journals. 

We're living longer than ever, but that means we now have to think about new issues that were uncommon when life expectancy was low. 

Muscles shrink and their strength dwindles as we age. When that is excessive, the condition is called sarcopenia, and it affects every third person over the age of 80, reducing mobility, autonomy and quality of life.

There may be hope in the form of a well-known drug, Rapamycin, that can delay the progression of age-related muscle weakness.

Are Proud Boys and Antifa fighting each other 'to oppose fascism' a product of the COVID-19 pandemic? No, militant groups have always attracted people with pathologies who just need a reason to be violent, but pandemics do cause social unrest, at least historically.

There is a lot more isolation than in past pandemics but also a lot more community around SARS-CoV-2, the 2019 form of the coronavirus that has locked up most developed countries. Unlike the past, where nature was just trying to kill us, and the randomness of it all caused panic, people know where it originated and how. We know how to mitigate it. We are equipped to try and help those with co-morbidities. A lot of people have died, no one downplays that, but a lot fewer than in any pandemic ever.

There’s a thin line between working hard enough and working too hard. Pushing your body to reach new levels of fitness requires commitment, effort and a willingness to put yourself through intense, challenging workouts on a regular basis.

But more isn’t always better. Without the right balance of rest and recovery you could end up spiralling into a long-term fatigue condition called overtraining syndrome. The condition results in long-term reduced physical performance, and may be accompanied by other physiological and psychological symptoms (such as low mood or poor sleep) – though this isn’t always the case. It can take weeks, months and even years to recover from this condition.

Did you read a paper saying we can prevent ocean damage under climate change scenarios by dumping iron into water to spur phytoplankton growth? Germans did, and were so convinced they began doing illegal live experiments. 

The model used a best-case scenario, which any entry-level chess player knows is a bad idea - they forgot to falsify their own hypothesis in their zeal to do something. A new paper notes that many ambitious climate action plans rely on climate engineering technologies where the risks are unknown. They are more like TED talks than real plans.
