3 more podcasts to listen to

I admit it. I’ve been bitten by the podcast bug. Not only can they be informative, they’re a good way to kill time. I like to jokingly call them conversations I don’t need to participate in (#introvert). Finding a good podcast can be hit or miss, but there is something for everyone. It can be interesting to find polarising podcasts where people love or hate them – I’m usually in the latter category and have quit podcasts after five minutes (hey, life is too short!).

I last shared five science-related podcasts and I’m back again with more recommendations!

Each of these podcasts have one thing in common – I was completely mystified by the circumstances! Plus, I think the level of deception and obsessive behaviour is something that can affect any of us at any one time. Each situation comes with red flags that are ignored at some point (and that’s definitely a post for another time)! Continue reading “3 more podcasts to listen to”

What’s the latest with COVID-19?

According to an editorial in Nature (dated 10 Jan 2022), it is time for us to come to terms with the fact that COVID-19 is here to stay.

Rather than laying plans to return to the ‘normal’ life we knew before the pandemic, 2022 is the year the world must come to terms with the fact that SARS-CoV-2 is here to stay.
Rather than laying plans to return to the ‘normal’ life we knew before the pandemic, 2022 is the year the world must come to terms with the fact that SARS-CoV-2 is here to stay.

Given the amount of pandemic fatigue there is at the moment, many people have already come to terms with it. However, as Nature states, this doesn’t mean that we should stop taking precautions to reduce transmission. With Omicron emerging as a serious threat to moving on from the virus, experts are stressing the need to continue wearing masks and social distancing.

“Omicron is a real threat. Omicron is much more transmissible, and it’s capable of infecting people who have been vaccinated or previously infected. If you’re going to get together with relatives and loved ones, test before you come together. And wear masks in public. And try to social distance in other circumstances.”

It’s also worth noting that the virus will continue to mutate and we will see more variants, but thanks to the ongoing research, scientists will be better equipped to handle them.

“I slightly suspect that there will be future variants, but I think with all that we’ve learned now, we actually should be able to deal with them with much greater certainty.” Professor Peter Openshaw Professor of Experimental Medicine

So, it might be presumptuous to say that this (vaccines, wearing masks, jumping three feet into the air if someone coughs nearby) is our new normal, but it’s our normal right now.

5 Science-Related Podcasts To Listen To

1. The Dropout

Money. Romance. Tragedy. Deception. The story of Elizabeth Holmes and Theranos is an unbelievable tale of ambition and fame gone terribly wrong. How did the world’s youngest self-made female billionaire lose it all in the blink of an eye? How did the woman once heralded as “the next Steve Jobs” find herself facing criminal charges — to which she pleaded not guilty — and up to decades in prison? How did her technology, meant to revolutionize health care, potentially put millions of patients at risk? And how did so many smart people get it so wrong along the way? ABC News chief business, technology and economics correspondent Rebecca Jarvis, along with producers Taylor Dunn and Victoria Thompson, take listeners on a journey that includes a multi-year investigation. You’ll hear exclusive interviews with former employees, investors, and patients, and for the first-time, the never-before-aired deposition testimony of Elizabeth Holmes, and those at the center of this story.

When I first heard about this story I was shocked it wasn’t more popular. So I was happy to find a podcast based on the entire saga and shocked at how far Theranos went.

Most surprising was that people with biological backgrounds were on board with an idea that seemed impossible – a testing system designed around a single pinprick of blood. I’m not an expert, but to conduct multiple assays you need to have enough of your sample. Even when mixed with reagents and diluted, a speck of blood is not enough.

It was fascinating to see just how much people believed in a bad idea. My takeaway was that sometimes there’s too much focus on the becoming ‘next big thing’ and not enough on finding ways to help people.

As of writing Elizabeth Holmes is on trial for various offences and the podcast is covering that also.

The impact of food poverty on society | part 2

In the previous part, I spoke about food insecurity and how it impacts the lives of many around the world. In this part, we’ll be learning what food insecurity is, and what measures are being taken to combat it and the last impact it has on society.

Food security is made up of four different components. This includes:

  1. Availability
  2. Stability
  3. Utilisation
  4. Access

What happens when there is a lack of food security?

The lack of food security comes with expensive drawbacks, and it may be cheaper to avoid food insecurity than to reverse it. Currently, most governments have been unable to come up with workable solutions. This leaves a hole that is filled by third sector organisations, some of which are not very secure themselves.

Food banks have become more common and they are plugging gaps in society. However, they are not a sustainable alternative to the real issue at hand – people are finding it increasingly difficult to survive in a world that keeps on evolving and growing, leaving those who can’t afford necessities behind.

The impact of food poverty on society | part 1

“Food poverty is contributing to social unrest. Add school closures, redundancies, and furloughs into the equation and we have an issue that could negatively impact generations to come. It all starts with stability around access to food.”

Marcus Rashford, Manchester United/England Football Player

Last year, Marcus Rashford, a young professional footballer threw himself headfirst into a campaign to ensure children in the UK were not left hungry during the COVID-19 pandemic. Initially met by resistance from the government, he was able to bring about something that has been lacking for years – action.

However, it’s worth noting that the best way to eradicate food poverty is to understand what it is and how it comes about. Many people in economically well off countries struggle to understand how people can’t afford to feed themselves or their children.

Taking a break from media

We need to take a break from the media including social media. That doesn’t mean I turn off the television and then I get on CNN online. That means I truly take a break. And children need to be taking breaks as well. … What we know about children is if they’re spending most or all of their time related to tragedies, that can increase their stress reactions.

Robin Gurwitch PhD

Lately, I’ve found myself picking up my phone, flicking through the same notifications and discarding it only to pick it up two seconds later. It’s difficult not to feel like this pandemic has been a missed opportunity to relearn how to enjoy ourselves without our screens, or how to learn or simply exist without them.

There is a lot of focus on maintaining communication with our loved ones via social media, but what about letter writing? How many people take the time to put pen to paper instead of the three seconds it requires to send a text message? How many of us send emails that aren’t work-related? Everything has been streamlined into micro-messaging and I’d argue that a lot of people don’t feel connected at all.

Still, taking a break from media isn’t just about not keeping in touch, it’s about mental clarity. We’ve been bombarded with so much information over the past year and a half that there’s no time to process it. There is no time to reflect. With our laptops, phones and televisions screens on, we are in a constant flux capacitor of information and we need a break.

“There’s a lot of stuff we can do that doesn’t involve a screen. We can get off our phones by subscribing to print magazines, or working on a physical puzzle. I’ve noticed a lot of people talking about a boom in escapist fiction – books that aren’t about a pandemic, really good stories you can get lost in.” – Tanya Goodin

I used to love reading books as a child and young adult, but with the popularity of social media and smartphones, I started reading on my phone. During the first lockdown in the UK, I created a huge spreadsheet of books I wanted to read – and proceeded to read four or five before I gave up. For the third (!) lockdown, I bought a physical book called The French Girl (and two ebooks). Reading the physical book was a revelation. At first, I struggled to get through a chapter. My fingers would itch for my phone, desperate to scroll through notifications! With time, I was able to sit through multiple chapters and switch off from the world for a little while.

As for the ebooks… I started one and got distracted by something else on my phone. The huge spreadsheet remains untouched.

Go figure!

AUGUST 26TH

  • 1938: a tape recorder was used for the first time to send a radio broadcast

pile of cassette tapes

  • 1743: Antoine Laurent Lavoisier was born. He is considered to be ‘the father of modern chemistry’ and is responsible for naming oxygen and determining what role it plays in combustion and respiration.
  • 1874: Lee de Forest was born. He invented the Audion vacuum tube which made it live broadcasting possible.

You learn something new everyday!

I like to post quotes that resonate with me from time to time and this:

…and this:

It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is most adaptable to change.

…caught my eye. It was attributed to Darwin, and I had no reason to believe he didn’t say it. The variations in the quote were probably a flashing neon sign that I didn’t see. Something compelled me to look up the quote online and it turns out it’s a misquotation.

One so prominent, it was featured in the California Academy of Sciences (until they removed the Darwin mention).

The real quote seems to be from Leon C. Megginson, Professor of Management and Marketing at Louisiana State University at Baton Rouge. While the quote itself is a good one, it is a lesson in knowing when to fact check and research (hint: ALWAYS!) – something I will do for all quotes I post in future.

Do you need to wear a face mask outside?

Face masks have become part of our new normal over the past year both indoors and outdoors. While they’re highly recommended inside heavily populated areas like supermarkets/grocery stores and public transport, there’s not much guidance when it comes to outside.

According to Monica Gandhi, MD, MPH, the risk of catching COVID-19 outside is quite low.

“The risk of outside transmission is very low because viral particles disperse effectively in the outside air. A study in Wuhan, China, which involved careful contact tracing, discovered that just one of 7,324 infection events investigated was linked to outdoor transmission. In a recent analysis of over 232,000 infections in Ireland, only one case of COVID-19 in every thousand was traced to outdoor transmission. And a scoping review from the University of Canterbury concluded that outdoor transmission was rare, citing the opportunity costs of not encouraging the public to congregate outdoors. Overall, transmission is around 5000 times less likely to happen outside than inside.” (Posted April 27, 2021)

… so, does that mean that we ditch our face masks and get some fresh air? With the vaccination programmes across the world coming along more efficiently and effectively we’re edging closer and closer to that point.

However, until it’s fully safe to do otherwise, we should all continue to maintain social distancing when around people who aren’t in our households, support bubbles or friendship groups.
