Is the future of cars Hydrogen?

Is the future of cars Hydrogen?

My wife and I have been away on holiday for the last month in the UK. If you're a regular reader of the newsletter you'll have noticed that Mark dropped me in it for turning up at Loch Ness in Scotland to check out the nessie experience. Mark set the expectation that I'd be writing an article about it.

What's Mike's number? - ideal CO2 levels

What's Mike's number? - ideal CO2 levels

In a recent newsletter, from Monday 24th November 2025, Mark featured an item about levels of CO2 in the atmosphere which was contributed by Mike Kearsley. Mr Kearsley sounds like he's been swayed by various sources of climate change disinformation. Mike asked us to specify what the optimum level of CO2 in the atmosphere should be.

Intuitive Eating

Intuitive Eating

Recently I was listening to the Inner Cosmos podcast, which explores the human brain from a neuroscience perspective. One of the episodes was about intuition, and the host was interviewing an Australian scientist, Joel Pearson, about intuition. During the interview, the scientist mentioned Intuitive Eating. This was a new term for me, so I thought I'd look it up and see what it was all about.

Matariki 2024

Matariki 2024

Most kiwis will be aware that this coming Friday is a statutory holiday, the recently introduced Matariki day - being on Friday June 28th.

Michael Shermer used to be a good skeptic

Michael Shermer used to be a good skeptic

When I first became interested in skepticism back in the 90s, I started finding communities on the internet (little did I know that we had our own skeptical organisation here in Aotearoa/New Zealand), and one of the prominent people I encountered was Michael Shermer.

Don the Astrologer

Don the Astrologer

Forgive me this short item, as it's been a pretty busy weekend. I had good intentions, but today my wife and I decided that we needed some more shelving space in our garage. I'd mentioned putting in another shelf below one that I had already installed some time ago, but she managed to convince me that it would be better to extend the Elfa wire rack system that we already have in our garage. What was intended to be a half hour job turned into a couple of visits to Mitre 10, and several hours of moving stuff around and installing everything. Still, we're very pleased with the result and we now have considerably more space to store various garage essentials.

A Beautiful Display

A Beautiful Display

Over this past weekend, we've been treated to beautiful displays in the sky at night, courtesy of space weather, and the sun ejecting some mass towards us - known as a coronal mass ejection, or CME.

Conspiracy loons update

Conspiracy loons update

A couple of weeks ago I wrote about the demise of RCR - Reality Check Radio, Voices for Freedom's media outlet that specialises in content for conspiracy theorists.

RCR gets a reality check?

RCR gets a reality check?

This past Tuesday the NZ internet was confronted with the sad news that Reality Check Radio - RCR as it's known - was “off the air”. On Tuesday morning, arriving in my mailbox that I use to monitor the thing, came this news:

Bibles for sale!

Bibles for sale!

It's April First, as I write this, which is normally a day where various pranks are played in the name of April Fool's Day. A quick look at the online newspapers doesn't reveal any obvious stories, and it would appear that, in the age of the internet, the day has lost its usefulness.

Effective Altruism at University

Effective Altruism at University

With the encouragement of Mark and Bronwyn from the NZ Skeptics committee, I attended a meeting about Effective Altruism at Rationalist House in Auckland on the evening of 13th March.

News on the news

News on the news

In the news this past week has been the announcement of the potential closing of Newshub at the end of June this year.

Crank Magnetism

Crank Magnetism

You may or may not have heard the term “crank magnetism”. I had heard of the term, but I'd completely misunderstood its meaning. Yes, this item is going to be a bit of a laugh at myself as much as anything!

New Neuralink News

New Neuralink News

Making the news this past week was Elon Musk's announcement that his company, Neuralink, has performed its first implantation of their experimental Brain Computer Interface device (BCI) into a human.

Dr Zach vs Rationality Rules

Dr Zach vs Rationality Rules

I recently watched a debate on YouTube between Dr. Zachery Ardern and Stephen Woodford.

Book Review: How Minds Change

Book Review: How Minds Change

I recently read David McRaney's book (on Kindle, from Amazon) on the recommendation of Melanie Trecek-King - one of our international guests at last year's conference in Dunedin. I was interested to read the book to gain insights into how to change peoples' minds about things that they're wrong about - or perhaps change my own mind about things I'm wrong about!

Barry Young and the data dump

Barry Young and the data dump

You'll no doubt have heard about the supposed revelations of COVID vaccine deaths recently revealed by an IT employee of Te Whatu Ora - a government agency - the MInistry of Health.

Our 2023 Awards

As it's an election year this year, there's been no lack of misinformation and nonsense being pushed at New Zealanders. Our runner up for the Bent Spoon award this year decided, apparently reluctantly, to start a new political party, called NZ Loyal. Liz Gunn, once a high-profile TV presenter, turned herself into a political leader and asked the conspiracy theorists of New Zealand to vote for her. Worryingly, given some of her extreme views, she received 1.2% of all votes, and she's already preparing her party for the next election. Next time round she might actually manage to submit the paperwork properly and have more than two candidates standing for election. We will be keeping a close eye on her.

Twin Flames: Twin Documentaries

Twin Flames: Twin Documentaries

And speaking of documentaries, there's recently been not one, but two short documentary series on streaming platforms about the Twin Flames Universe cult, each with three episodes.

Beware of Netflix documentaries

I've recently become aware of a controversy surrounding the discovery of Homo naledi, which was the subject of a Netflix documentary film: Unknown: Cave of Bones

NZ Skeptics AGM

As mentioned above, during the Sunday lunchtime of the conference we'll be holding our Annual General Meeting. If you're a member of NZ Skeptics you can come along (even if you're not attending the conference) and hear all about our business. We'll also be attempting to run a livestream of the meeting in case you can't attend in person.

Ārepa

Ārepa

I have a feeling we've written about Ārepa before, but as a refresher, it's a kiwi brand that produces “health drink” products that claims to make brains work better.

The latest scam “wellness” product

The latest scam “wellness” product

There are plenty of scam wellness products on the market, but the latest one to catch my attention is a fancy water bottle called LumiVitae CellPower. You can pre-order your very own in either Anthracite Gray or Champagne Gold for the bargain price of $845.

The amusing emails we get…

The amusing emails we get…

As I've written before, we occasionally get people emailing the NZ Skeptics committee with their various “theories” about how things work.

Liz Gunn and the MOAR

Liz Gunn and the MOAR

We've reported previously on Liz Gunn, the former TV presenter, now turned conspiracy theorist, who was the leader of the NZ Loyal political party. Her party received just 1.2% of the party vote, therefore denying their representation in parliament.

Gender, Vaccines and more…

Over the past week or two, I've been having email conversations with a person from the other side of the skeptical fence. This person I'll refer to as Mark - which is his real name, but I'll not give any more information about him. (By the way, our skeptical newsletter writer Mark Honeychurch has sworn he's not running some elaborate joke on me!)

Webb Update

Webb Update

We certainly live in exciting times. There's been recent news about some potentially exciting discoveries made by the James Webb Space Telescope (JWST).

On Near Death Experiences

On Near Death Experiences

There was a recent RNZ interview done as part of their Expert Feature series, which runs on Monday afternoons with host Jesse Mulligan.
