The first seedless grapes were kind of an accident. Thousands of years ago in the Middle East, a random genetic mutation caused a group of grapes to spontaneously abort their own seeds before the seeds could develop hard casings. The result: seedless produce. To reproduce the fruit, a sly farmer simply cloned the vine (with no seeds, there?s nothing to plant)?meaning that all seedless grapes today are direct descendants of that one mutated grape vine.

Tragically BBB, that one is strange but not true. :(


They're different from mammals in the sense that the waste pipes for both the kidneys and the intestines use the same pop hole, but the intestines have the same basic function using gut flora that have a gaseous by-product.


When the gas pressure exceeds the elastic strength of the cloaca muscle, the result must inevitably be a fart.

Snopes and others say seagulls do not explode from bicarbonate/calcium carbonate etc. I agree. I think anyone who was paying attention in anatomy and physiology would as well.


The theory that when gas pressure exceeds muscle strength, then the muscular closure will be opened by the presseure, must surely be true for the esophageal sphincter as well.


The fact that rats and many other animals inc horses don't vomit is not related to this. Vomitting is an active reflex; whereas, gaseous escape is an involuntary release. In addition although horses don't actively vomit, the accidental ingestion of too much of the wrong type of feed will cause distention of the horse's relatively small stomach (most digestion takes place in the large hindgut through fermentation), leading to stomach fluids being involuntarily exuded through the nostrils. This is a vetinary emergency requiring immediate supervision. I haven't seen this in rats, but I have seen profound bloat in mice, which also cannot vomit. In the case of bloat, a dysregulation of digestion has occured most likely in the hindgut due to illness. The gas pressure is trapped between the many internal valves of the digestive tract and cannot escape rapidly enough to relieve the bloat. In a larger animal you would be able to surgically release the gas. Sadly in mice you're best to euthanise them in this case.

    • hallo, Do you have a suitcase for a student going to Ghana to teach sports? Taking a parachute, cones, mini hurdles, batons and dodge balls and a pump, then leaving it there for the school If I could have any old suitcase please it would be amazing! Thank you
    • Looking to borrow a gazebo for birthday party this Saturday, can you help? Julian - 07961463111
    • Whilst I agree, I have been thinking about this recently in relation to some of the other posts on here about anti social behaviour. We are all products of our upbringing - our experiences at home, school and beyond - plus whatever we have inherited genetically which might affect our behaviour (the nature/nurture thing). So in this case, if people haven't been brought up to love and appreciate trees and other wild things, plus as you say they may be deeply unhappy (or have other undiagnosed issues) it's easy to see how they could have ended up doing this. Also, it's possible they had quite low intelligence and didn't really grasp what they were doing and the effect it would have on so many other people. But that's just surmise and possibly completely wrong. From what I've read about it, they seemed to be two mates egging each other on, like two big kids. I'm not for a minute excusing what they did, and it's right they should be punished, but I really hope they might get some sort of rehabilitation in prison (it would  be appropriate to have them do some kind of community service like planting saplings, wouldn't it, or working in woodland conservation). And the same goes for phone robbers and shoplifters (rehabilitation, not planting saplings), though for SOME  shoplifters there might also be other issues at play, not excluding poverty. Sorry Jasonlondon,  I've gone off at a real tangent here, lucky it's in the lounge! Oh oops I've just noticed it isn't. Sorry admin. Oh, and then there's a whole philosophical discussion to be had about free will and determinism ..... 🤣🤣🤣
    • Thanks! I'll find out in a few weeks when I get the results! It was one of those disconcerting things where a disembodied voice keeps booming  at you to breathe in and hold it, then breathe normally. Apart from that it was OK, all completely painless. I imagine there will be quite a few people going from ED, though I presume it covers the whole Southwark area
