"That'll learn us."
That'll be a first then, or did I miss the sarcasm?

Neutrinos and anti-neutrinos are neutral, no charge hence the name. So how does the theoretical lack of a neutrino or anti-neutrino (or two) impart a positive charge to the inside of the chamber?
Neutron (no charge) decays producing a proton (positive charge), an electron (negative charge) and an anti-electron-neutrino (no charge). Charge is conserved as the proton and electron cancel each other's charge. Do it twice still no net charge.
Must be fucking magic! Unless some how the energy the anti-neutrino would normally have carried away from the decay (neutron being slightly heavier than a proton plus an electron) gives the electrons enough extra velocity to escape the germanium thus leaving a positive charge.
Any ideas?
No it's not that would be the gluon (strong force boson).
These are the Strange and Charm quarks themselves arranged as the tri-quark particles known as baryons. Presumably as SSC or SCC in the various colour configurations; it's not mentioned in the article just the masses/energy of what they found.
The Omega particle itself is SSS, the significance here seems to be it's the first time a baryon has been found which contains both Strange and Charm quarks.
The Cern boffins hope it will help shed more light on how the strong force works.
My folding Sennheisers bought 20 years ago (to replace the cassette Sony Walkman ones) are still fine and still sound excellent. The Walkman's rubber-band rotted away years ago unfortunately.
My Psion 3a was still working in 2012 when I abandoned it as there was nothing left that it could talk to.
Unlike some (cough *Dabbsy* cough) I learnt not to be heavy handed with delicate kit.
Brontosaurus is a constructed noun combining the Latin words for thunder with lizard so it is Latin for all intents and purposes.
Brontosaurs and brontosauri are both listed in the OED, brontosauruses and brontosauruss are not.
However all the above are now obsolete: Brontosaurus: noun - former term for apatosaurus. Time to update!
Yep it's called the 'barycentre' - the centre of mass of two (or more) mutually orbiting bodies! The earth-moon barycentre is within the earth's radius rather than being in free space.
Humm... a magnetic white dwarf begs the question is it an 'iron' white dwarf rather than an oxygen/carbon one?
Until the thing is rooted. Nowhere have I seen any info about what protection from on-line fiddling the Echo has, if any. If it connects to the web it can be hacked. Is the mike-mute button even part of the hardware loop?
My ex also came with a button and that..... oh never mind.
We had an African Grey parrot that could mimic everyone in the house to a T and it would have the dogs excitedly milling around the front door with "come on girls, walkies" several times a day. If the dogs couldn't work out it was the bird and not one of us then I doubt that Alexa could either.
My sister gave me an Echo for Christmas and after reading the leaflet I politely suggested she return it as I did not want a spying device in the house. She then asked me to see if my daughter would like it. Daughter's answer was "Ah... hell no! But say it nicely."
The since deceased parrot's worst trick was to respond to a cough with a rolling medley of my parents', sister's and my morning smokers coughs. It got even more gut wrenching after my grandfather spent two months with us while dying of lung cancer and the bird adding his cough to the medley.
So one in a thousand (0.1 per cent) is considered ultra-rare and/or rarer-than-rare? Not quite as rare as say carbon dioxide in the atmosphere at 400 ppm (0.04 percent). Yet there are two of these rare objects shown in the cover picture.
And why use "0.13 billion years" for the ring's age, is it more meaningful than say "130 million years old"?
For sexually reproducing organisms I was always taught that they are the same species if they have the same number of chromosomes AND can produce non-sterile offspring. Breed donkey and horse and get a mule or hinny, both of which are (nearly always) sterile, as horses and donkeys have different chromosome counts and are certainly different species.
Different sub-species should always produce non-sterile offspring.
Interestingly did recently read that the modern man/Neanderthal cross-breeding produced reproductively capable females but sterile males; hence no Neanderthal X chromosomes in the current human genome (no matter what the feminists say to the contrary).
