Does nose breathing enhance cognitive performance?


This sounds a little weird right? But the research I am talking about has been  published in a respectable journal ( Journal of Neuroscience 22 October 2018, 3360-17 ) by a group of bona fide researchers in Sweden. So, let’s take it on trust for the moment. The research tested two groups, one of which breathed through the mouth and the other throug...

Will quantum computers kill AI as we know it?


Sigh, I can’t help taking aim at AI. It’s just so fashionable and politically correct. Ask anyone in leadership positions in politics or the private sector what the future is, and they will all tell you seriously it’s all AI, OF COURSE. I have this pressing need to knock down shibboleths, even it they are good ones. So here goes. Here’s my question...

BREXIT is just a sideshow – the main act is European disintegration


It looks like BREXIT is a mess. It’s fiendishly complicated. I already posted on this in 2016 (“ BREXITed - UK Gain, EU Pain ”). My thesis was that BREXIT would hurt the EU far more than the UK. Now I’ve had more time to consider the issue what’s my lowly opinion now? My opinion last time concerned the short-term, what would happen in the next 5 ye...

The California wildfires - Stay in your car in a wildfire – don’t get out of it!


The fires in California are tragic with a huge loss of life. I grew up in Australia in the bush and we used to get a lot of bushfires. They are very scary of course but the Australians have built up a hard core of safety knowledge based on bitter experience . I am doing this blog as a public service because I am surprised that none of that experien...

Two wheels good, four wheels bad (as long as they’re octonionic)


It seems that Americans, especially millennials don’t want to drive any more or own cars. Part of the problem is that the average commuter spends three times as much time in their annual commuting that they do on vacation. Hmmm but how about those Teslas? But I get it. Muscle cars are out; electric vehicles are in. Metrosexuals for EVs right? But h...

Ban tourism to slow down climate change?


You’ve no doubt heard that Venice is flooding due to climate change. Now we know that it’s also being flooded by tourists. As a result, the locals are leaving as the tourists ruin the city with too many people. A similar thing is happening in other tourist cities of the world. Santorini, the Forbidden City, Florence and so on an on. Tourism is rapi...

The imminent Great Global Final Biological Collapse; can reverse gene drives prevent it?


That sounds like an overly alarmist headline, right? So get this: “ Hyper alarming’ study shows massive insect loss ”. Apparently over the past 20 years insect populations have declined on average 50% and in some cases even higher. We’re all seeing it. Have you noticed that these days the number of love bugs plastered over your windscreen and headl...

Are those missing aliens lurking in the hidden dimensions of string theory?


Another day another UFO. Did you see the report that one was seen over Myrtle Beach in August of this year? Hmmm, Fox News, maybe it’s fake news? But then again, maybe not. You might have also noticed that three navy pilots tracked a seeming UFO late last year using Raytheon radar mounted in US navy fighter jets. This report was carried by Raytheon...

Are fruits and veggies bad for you?


In the category of believe it or not: “ Zoo Weans Animals Off Fruit Because Its Increased Sugar Makes Them Fat and Rots Their Teeth” . BTW the zoo is in Melbourne, Australia. Are these Aussies crazy politically correct, or just plain crazy?  Full disclosure: I’m a card (viz. passport) -carrying Australian. As in Fosters, Australian for beer. G’ day...

A Turing test for AIs that have passed the Turing test


You know the Turing test, right? You communicate with a computer by typing and it must guess if you’re a human or an AI. The test has been run for many years. Usually the humans have won but the AIs are catching up. So now some inventive academics (yep, they even exist) have devised a new Turing test; instead of doing a typed conversation you just ...

Mental health needs disruption on a massive scale!


It's estimated that 20% of Americans have a mental disorder of some kind; BTW that’s 44 million people. Around 70% of youth in juvenile justice systems have at least one mental disorder and at least 20% live with a serious mental illness. Another 20% of State prisoners has mental disorder. Nearly 1 in 2 people – that’s all of us now - will suffer f...

Is vaping actually a medical breakthrough?


If you’re a teen, or even a tween, not to mention over the hill in  your 20s, you will know that vaping is cool ; in fact way cool dude. The King of the Hill in this neck of the cottonfields is Juul , the maker of the market-leading e-cigarette. Of course, it was too good to last. The spoilsports in the FDA not to mention States legal eagles are co...

Wrinkle recognition?


Facial recognition is hot now. The software is now so good it’s being used for crime prevention and apprehension by law agencies. This is leading to a revolution in law and order as we speak. Did you see the research that links particular types of wrinkles to heart disease? Apparently, these wrinkles are a good predictor. So, what I’m wondering is ...

Is alcohol worse than smoking?


I’m sure you noticed the recent report about drinking alcohol. It’s based on an article in the Lancet , the British medical journal. Its well-known to be an authoritative source so that gives the report a high level of street cred. In sum, the article concludes that there’s no safe level of alcohol . No matter how little you drink, it carries a def...

Will climate change cure baldness?


Yep I know that I’m raising yet another hair-(sorry) brained idea, but consider it wishful thinking on the part of a hair-deficient yet hopeful male (viz. me). My idea is that climate change will make males like me hairier. That’s why so many males don’t care about – indeed heartily wish for – climate change; the more the merrier. What evidence, yo...

Can AIs have will-power?


With AIs it’s all about intelligence and smarts. Can they think better than us? Will they make better decisions? And so on. Probably the answer to all of these questions is yes, eventually if not sooner. I’m a (poor and slow) runner so I like to read books about running to see how the really good ones perform. I just read the semi-autobiography of ...

How about the new amazing intermittent fasting pescatarian diet?


Paleo, keto, Mediterranean, Dr. Atkins, Weight-Watchers. So many diets, so little time to lose weight! What’s a girl to do? Your company might help you out by making you a vegetarian, as the phenom WeWork has done recently. The company will no longer serve any type of meat nor reimburse you for a burger. Tough right? It’s officially now a vegetaria...

Are electric scooters the next mega-extinction event on Earth?


  I suppose you have seen the latest techno-phenomenon, namely electric scooters (" Electric scooters are invading. Bird's CEO leads the charge "). Now you can go to work on them by just getting their app and unlocking the contraption. They are supposed to be leading to reductions in traffic and maybe they even are.   When I go to China I see the d...

Deepfaking neuroscience


  Have you heard about deepfaking? Yep it’s a real word, albeit very new. Deepfaking is about how you can modify a video in such a sophisticated way that it’s impossible to tell it’s a fak e.   That’s gonna put the cat amongst the pigeons right? Who will ever know what anyone ever said about anything once this stuff goes global, which is happening ...
