  • Good question. According to this article, the process going on with Betelgeuse does sound like the same or very similar to the process described in OP’s article.

    The great dimming [of Betelgeuse] was caused by the star spitting out a lump of gas and dust, like chewing gum: or what scientists call a “surface mass ejection” caused by an “anomalously hot convective plume”.

    OP’s article doesn’t say that the Old Smokers they found are red super-giants but since they called them old smokers, I’m inclined to think that they are. Also because they say that smoke contains much higher levels of heavy elements than is common in the region which would also be consistent with older stars. The article doesn’t say whether or not the stars puff out smoke on a regular schedule like Betelgeuse does, but then maybe they haven’t been watching them long enough to see a pattern yet.

    It does seem like they found a bunch of older stars that are pre-supernova, just like Betelgeuse is, and burping out clouds of gas and dust.


  • Every cat is different. We have one cat that goes nuts for plastic springs, another loves little furry ball toys, another loves balls made of crinkly plastic material. Last Halloween my wife bought a bunch of mini ping pong balls that have a sticker making them look like eyeballs. All our cats love those things. They also all love fishing pole toys.

    I recommend getting a variety of toys and seeing what your cat loves best.


  • I’ve had two over the last decade or so.1st was a cheap 110v that couldn’t run the jets and the heater at the same time. It was, as another poster mentioned, very fickle about the chemicals. I started out using chlorine but later switched to bromine. Mainly I hate the chlorine smell, but bromine does better in hot water anyway. Even so, I was forever testing and fiddling with the chemicals. Hot tubs are touchier than pools. Warm water is a great environment for bacteria so if your ph and sanitizers are off, the water can turn nasty pretty quickly.

    When I moved, I left that one behind and got a much higher end spa. This one is a 240v and has much stronger jets and can stay hot when I’m using them. I’ve also switched to something called the Frog System. Get your tub ph, alkalinity, and everything set and toss in the two part floater. The first part has a mix of minerals that slowly dissolve. The second part is the chlorine. It attaches to the first and floats underneath is. As the chlorine dissolves, the whole thing slowly rolls over. Once the chlorine cartridge is floating on top, you replace it. Every three months, you replace the mineral cartridge. It is incredibly simple to use and I’ve pretty much stopped testing the water because the system seems to be maintaining everything perfectly. I’ve had to adjust the alkalinity once in the last year and that’s it. I’ve never had to add any other chemicals since I started using this system. As an added bonus, I rarely notice the chlorine smell. I highly recommend it.

    As for the people who talk about bugs and stuff in the water… you need a cover for it. If you leave it open, of course it will get nasty. You also can have problems with vermin. If there are openings in the shell, including the bottom, mice will likely get in. Whenever it gets cold out, that hot tub is very inviting to them. If they get in, they will probably start chewing wires and die horribly while costing you a bundle in repair costs. Put the tub on some sort of pad, concrete or otherwise, to stop vermin from tunneling underneath and watch for and damage on the shell where they might try to chew their way in.

    If you are like me and love a long hot soak once or twice a week it’s great. If not though, you may regret getting one. They can be a lot of work



  • Going to bed earlier isn’t an effective solution for many kids. Around 1 in 6 adolescents find it difficult to fall asleep before 11:00 PM.

    In adolescence, up to 16% of teenagers experience a sleep phase delay. Due to this circadian shift , their melatonin levels don’t begin to rise until later in the evening. As a result, they naturally feel more alert at night, making it harder for them to fall asleep before 11:00 p.m.
