Helium
Helium. Who needs it anyway? Well, as it turns out, helium isn’t just about party balloons and doctors around the world are worried about a global helium shortage. Helium is used in MRI machines - each MRI needs about 2,000 litres of ultra-cold liquid helium to keep the MRI magnets cool enough to work. Helium, a nonrenewable element found deep within the Earth’s crust - is running low. Part of the global helium shortage is due to a failure in a crude helium enrichment plant in Texas and declining or unreliable production from existing sources, and the delay in Russia’s helium facility coming on-line. This is the fourth time the world has suffered a helium shortage since 2006. As well as balloons and MRI, helium is also used in high-speed internet, computer hard drives, airbags in cars, and as a coolant in nuclear reactors. It’s also used in weather balloons - which are released from 900 locations worldwide a couple of times a day. Hopefully the helium supply will improve soon, and that there are plans in place for dealing with Helium Shortage 5.0 should it happen.
Up front training
How much training should you have before you can run “front of house” at a cafe? We went to our usual Sunday morning venue today - and, admittedly it has had a change of management and it would also seem a change of staff, but you would think they would still be able to run a cafe properly … like knowing how old the croissants are, and when the jam is out of date … and to deliver the take-away coffee order (for multiple cups) to the table, the same way the previous management did. I was not impressed. But then, when collecting the coffees from the barista, that the server (who managed the get our coffee order wrong) was just “filling in” - I would suggest not very well but then again it might have just been that he had no specific training or maybe he was feeling put upon because he had been called in to work on the till. It looked as though there wasn’t much help for him either, so that might have been affecting his performance a little as well.

The long and short of it
Why did the T-Rex have such short arms? A study published in the journal Acta Paleontologica Polica suggested that the T-Rex evolved short arms because they fed in packs - and by having short arms it meant they wouldn’t bite off each other’s arms. Or was it a matter of the arms didn’t get shorter but that the legs got longer - that’s a suggestion put forward by John Hutchinson at London’s Royal Veterinary College who is an expert in the biomechanics of movement in large terrestrial animals - both living and extinct - who also noted that there was no way we could really know what was involved or the triggering factors. It is interesting to think about this piece of evolution differently though - because we do tend to think of T-Rex anatomy and the short arms that way.

Droning on (no, not really)
Following some close-up viewing of drone footage last week, I decided it was time to think about pulling my drone out again for another "go". Or was it? I've never had much luck with it ... the battery life is not great (12 min) and it is quite light which means I haven't been able to take it out flying if there was even a whiff of a wind. The drone and I have spent some time together - mostly stressful as it tried to fly away or fly at me or be somewhere so far away that I couldn't actually see it anymore and had to search the (practice) sports field to find it. Hmmm ... is it possible that what St was saying was true - a $600 drone is going to fly better than a $100 drone especially when the $600 drone has GPS and a good interactive app and good instruction information including lots of Youtube videos explaining the features and functions of the drone. So I have purchased a new drone - the DJI Mini 2 - which does HD stills and 4K video as well as a selection of "QuickShots" - pre-programmed modes for the drone. I watched a couple of instructional videos on Youtube last night and took DJ out this morning for its first flight (only because there is now a "no drones in the house" rule). I was impressed. Usually I can't get a drone off the ground and flying in a straight line - but this one was up and flying within a couple of minutes. I loved that I could set a height and distance maximum - so when I was in the middle of the field, the drone was never going to go outside the field - so there would be no chance of losing it in the surrounding bush - which had always been a worry with the other drones.
I have a lot to learn about DJ but it is gratifying to know that it is going to be "fit for purpose" and not the source of a constant sense of anxiety and stress - like the previous drones.
Footage from the first flying is shown below.

CoVid Brain
In the end I did what I could - hoping it would be enough - and submitted the assignment last week and I'm now waiting for the result. I had decided, quite uncharacteristically I think, that if I needed to re-submit, that would be okay, because the lecturer would tell me what areas needed to be worked on and hopefully also provide some pointers about what needed to be done ... they're there, afterall, to help!

Jurassic Park
The next movie in the Jurassic Park franchise is now only a couple of months away and the promotion for it is flying thick and fast. I was hooked from the teasers before the Beijing Winter Olympics and with each new release I am getting more excited. The latest promo was released only a couple of days ago: Jurassic World Dominion Legacy Featurette. I checked on the Outlook site to see when the film is due for release in Australia. The worldwide release dates are shown - but it seems the world has shrunk to include only Canada, Germany, the UK and the USA. Hopefully they remember to bring it to Australia because it's a long way to go to see a movie - but we'd do it!
Now ... that's lucky!
We had a lesiurely breakfast at a cafe which supplies newspapers for their customers to read - which is how we chanced upon the story "Alleged acid attack appears on TikTok". It seems a TikTok "personality" was live-streaming as she was waiting outside a Sydney restaurant on Friday night when police say three masked men got out of a black Mazda SUV and approached her before allegedly attacking her with a chemical substance. The attack was caught in her live stream. She continued a live stream from the Hospital where she was treated, saying how lucky it was she had "... my glasses on. Imagine [if] I didn't have my glasses on." Yes, thank goodness she was wearing her sunglasses at 11.15pm at night when the incident occurred. Were they her glasses? I had a look at her account on TikTok and the couple of times I saw her with sunnies on, they seemed quite different from those pictured in the live stream of the attack. Yes, that it was one lucky "personality" - and she did not sustain serious injuries in the attack. First responders were not as lucky and it has been reported that a number of them suffered chemical burns while on the scene. Saturday, April 16, 2022
Life imitates art
Let's call them Murder Dogs. I first saw them in "War of the Worlds" where they were roaming the countryside sampling human DNA. Unfortunately that required them to shoot a bolt into people's foreheads. Since then I have seen pictures of then in the real world in Shanghai where at least one remote-controlled robot dog walks the streets with a megaphone strapped to its back. The robot dog is about the size of a terrier and barks orders to residents: stay inside, wash your hands, check your temperature.
The "dogs" have been adapted for military use as well. I'm not sure if they are remote-controlled or autonomous - but either way they are a scary proposition if they're on your trail.

Let the games begin ...
Current PM Scott Morrison has already come out swinging - making less than polite comments about Mr Albanese's physical appearance. This may well be one of those elections where they criticize the person rather than the policy. It used to be that that was a sure sign that someone was "losing the argument" but it doesn't seem that it works like that these days.

Waiting ... waiting ... waiting
So how many chances do we give them? I had one guy lined up to do the lawns and after the third unsuccessful try to raise him, I finally, and reluctantly, because he is very good when he does do the lawn, had to try someone else ... I say "try" because, I think it's 10 days later, and they haven't turned up yet ... although, they have now sent a text saying they're planning to be here tomorrow. Fingers crossed!
