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.

    • https://www.assistancedogs.org.uk/information-hub/assistance-dogs-emotional-support-dogs-and-therapy-dogs/   hello   i’d be interested to understand if anyone.has experience of Assistance Dogs especially for autistic children of different ages for emotional support and therapy   There was a prior thread on this topic on EDF 10 hrs ago but it had limited experiences and there was a (claimed) change in UK legislation in 2019. Whilst the industry appears unregulated/unlicensed, there are several providers (approx 15, perhaps more) who claim to have fully trained dogs or say that they can help families to train a puppy/young dog over the 18-24 months.  The latter obviously comes with a need for strong commitment to the challenge. Costs for a fully trained assistance dog are quoted at £13-15k albeit they claim £23k total cost to train the dog. On the one hand, this could potentially be a useful solution for some families if such a dog was truly trained as their websites claim and such a dog was accepted in public places and schools etc… On the other hand, I don’t think that I’ve ever seen an assistance dog of this type or in this context (only for a blind or partially sighted person) and hence a real risk of fraud or exploitation! The SEN challenge for families coupled with limited resources in schools or from local authorities or the NHS as well as the extremely challenging experience of many families with schools offering little or no support or making the situation worse leaves a big risk of lots of different types of fraud and or exploitation in this area.          
    • Hi there  We live on Woodwarde Road backing on to Alleyns Top Field.  Our cat Gigi has gone missing — it’s been about 24 hours now. She is a cream Bengal. Could you please check sheds, garages, or anywhere she might have got stuck please? And if you could keep an eye out or share on any local groups/forums, we’d really appreciate it. Photo attached.   Thanks so much! My name is Jeff on 07956 910068. 
    • Colin.    One for the old school.   Just saying.
