Physicists discover a heavy cousin of the proton at CERN’s Large Hadron Collider CERN scientists have discovered a long-predicted heavy cousin of the proton, finally solving a 20-year mystery. Date: March 19, 2026 Source: University of Manchester Summary: A new subatomic particle known as the Ξcc⁺ (Xi-cc-plus) has been discovered at CERN’s Large Hadron Collider. This heavy proton-like particle contains two charm quarks and was detected using the upgraded LHCb experiment. Scientists observed it through its decay into lighter particles in high-energy collisions. The finding confirms predictions and settles a decades-long question about its existence.

In the science fiction story Lexxx, the Earth was destroyed by the superconducting supercollider in Texas, and not CERN. That is correct?

But the SSC was never built.
They did finish the helium plant in Waxahachie. We supplied the cryo instrumentation.

Nice.
I was thinking with ever more knowledge of ever smaller particles will we see chips that use interactions of those? I mean we are now into electrons and holes, but go an order of magnitude smaller, more on a chip. OTOH when you look at large colliders, to me is like shooting 2 Tesla cars at each other at supersonic speed. Sure, you may find some bolts and nuts, but will you ever figure out the inside of the chips in auto-pilot and their programming? You will find all sorts of shrapnel though... I really have no clue as to what 'quarks' exactly are, just math ideas?. So: " If you cannot do it with those small particles on the desktop then you will not be able to do it in a machine the size of the Universe. "

Even in 2006 (twenty years ago), electronic engineers already needed to be concerned about nanoelectronics (though where I used to be then used to still be officially called in terms of microelectronics), and to be concerned about Single-Event Transients (SETs) for spacecraft as distinct from Single-Event Upsets (SEUs). At small scales, even non-space applications are affected by radiations.

When it comes to computers, I am thinking that the 'Heisenberg uncertainty principle' is not really wanted. Yes there is 'on' and there is 'off' in logic gates like 'flip flops' but you do not want them jumping back and forth between the two. You want a '1' to remain a '1' and a '0' to remain a '0' until a read-write or chip select signal is to be sent and only at that time can you set a '1' to a '0' or a '0' to a '1'. There is also 'dynamic RAM', 'flash drives', and other phenomena but the general idea is that you do not want random '1's and '0's to appear except when a read-write is happening.
As for 'quarks' I am thinking there is supposed to be a 'strong force'. In general the 'nucleus' of 'atoms' is supposed to have certain 'charged' materials in them called 'protons'. These 'protons' are all supposed to have a 'positive' electric charge that repels each other. The 'strong force' is supposed to be a strong force that holds all of those 'protons' together in a 'nucleus'. Then there is a 'weak force'. The 'weak' force is often much 'weaker' than the 'strong force' in a lot of circumstances. In general, it allows the interconversion of 'protons' into 'neutrons' and 'neutrons' into 'protons' (also involving a 'little neutral one' in the process some times called a 'neutrino').
As for 'quarks' I am thinking it has to do with the phenomena involved with building of 'protons' and 'neutrons' and not just 'electrons' and 'positrons'. Then of course there is that ancient Carl Sagan's 'can you know a grain of salt'? Well, it might be difficult to memorize all of the specific positions of every sodium and chlorine atom in a grain of salt. Can you simplify, however? The 'sodium' and 'chlorine' atoms in a 'crystal' might have certain relations with respect to each other? It might be possible to simplify.
Then of course there is 'Broca's Brain'. In it there was speculation. Could one read the positions of 'neurons' with respect to each other in a preserved 'brain'? If so one might be able to 'read' the 'information' in the preserved brain, simulate how those interactions of 'neurons' might have gone on when the 'brain' was alive, and then in a limited sense that 'person' might 'live again' in the simulated world.

If I was a brain cell and had to remember things, a lot of things, I would store it locally in DNA or RNA Nature is very efficient,
Maybe one day we can transfer 'wisdom' by a simple copy of DNA / RNA Like nature does :-)
B
Bill Sloman
It doesn't. If you wanted to copy memories you'd have to copy a whole set of DNA molecules and the way they were interconnected.
Nature transfer instincts via heritable DNA, but that's much more basic stuff than wisdom.

Totally disconnected from reality. That is not how the brain works. The brain stores information by changing the nature of the interconnections between the nerve cells. They change them based upon whether the nerve cells fire or do not fire, and that can be based at least somewhat on sensation from the environment. The DNA and RNA code for proteins that do that when the cells fire. It is pretty much the same DNA/RNA for humans and animals. The uniqueness of our thoughts and memories have to do with the specific connections between the nerve cells.

That is the old view / model. done some coding with that model. It raises the question if 'nerve cells' apart from building bias also store the signals in time and amplitude and chemical composition There is more than an electric signal between brain nerve cells, actually there is a chemical transport that may contain different things Humans will find out if not already did.

Yea there are various levels of knowledge on many subjects. I am thinking that when I comes to microscopy of the nervous system I once took a class. on various subjects. I am thinking that when nerve cells are often studied the tissue is first exchanged with organic solvents, and then wax. Then the wax is cut into slices. Then the slices are placed on slides and the wax is re-exchanged with organic solvents.
I have also, to the best of my recollection not made a diary entry for either today or yesterday.
Sorry.

That's the traditional method, the thin slices are cut with an extremely sharp blade in a machine called a Microtome. I used a scrap microtome as the basis of a machine for recording audio onto wax cylinders, because the bedways were so accurate.

once worked in the chemical lab of a big university hospital for a while. All sorts of cool equipment, from mass spectrometers to DNA research related and interesting things the students came up with for their projects, help design electronics for those. Had to keep the equipment running or fix stuff if needed,
But I am no chemical genius like Bill.
If I had to start again as a kid today, maybe I would have gone into DNA stuff and design my own Dinos.. Or president ;-) This US one needs a make-over!

Yuck. Pretty pictures from machines called television sets and radios that are not actually true.
I remember back in college however a class where there was this biochem professor where there was this cow's liver and I am thinking there was centrifugation and electrophoresis to get enzymes from it to test the dynamics of the enzyme reactions. Some of that stuff is cool.

Hmm. I am thinking that an exaggeration is a lie.
I think that most things on television fall under the category of 'fiction'.
'x' is a variable that I type into a thunderbird usenet reader. I think it involves one keystroke. Not everything involves only one keystroke nowadays.
I am thinking that the 'A' stands for 'artificial'.
If I answer 'no' I am arrogant. I can only guess that I am human.

Depends, but I do not see all channels, just have more than 400 here -- on satellite -- plus a few local ones.
I like the 'that's' music channels on Astra satellite (English) and sometimes follow the 'place in the sun' channels on Channel 4 (people looking for cheap property in warm and nice places), Beep Beep See news, CNN, Al Jazeera, some financial channels,.. Many German channels... ZDF-info etc, videtext / ceefax / teletext... pity the Brits dropped ceefax. Usually do a quick check in the morning if there is anything that may be of use, some Dutch channels that test stuff and companies... program a recoding so I can see it when I have time Survival channels on German TV are sometimes interesting too, you can learn tricks from that, may come in handy if the white in the nut-house get worse. Have not watched a movie in maybe a year. Probably seen many, most?, recorded some too.
I worked in broadcasting here for many years, starting in 1968, some stuff was still using tubes back then, even orthicon cameras

designed my own vidicon camera in 1968,

think that got me the broadcasting job, before that I worked for army, navy, power stations electronics.. Things became color here with e PAL color system and we had plumbicon cameras.

After I left broadcasting I was all over the globe... doing all sort of things.. even space and Navy guided missiles related. Now back in the Netherlands... Had a TV repair shop here too for some years. But who knows...
I dunno, I wrote my own Usenet newsreader many years ago, ported it now to Raspberry Pi4, have not released the Pi yet, still testing. I have a Usenet database on this Raspberry Pi that goes back to 2006 with postings I did and postings I found interesting that I saved, has a search function too. Likely even older Usenet on old PC in the attic,
'X' is also the name of Musk's babble network..

Yes, was just curious, I sure would not be surprised if they tried infiltrating Usenet with a bot - if they not already did, or will if they read this :-).

I did get a Ph.D. in chemisty, and I was pretty good at it - as you'd expect when both my parents were chemists - but I wasn't any kind of chemical genius, and I don't think I've ever run into one. People like Einstein and Dirac may rate as geniuses but the nut cases on sci.physics.relativity wouldn't agree.
I don't think that anybody has clue what is wrong with Donald Trump at the genome level

seems to think that if you get the genetics right you could fix society, but his books makes clear that thousands of genes correlatate with the high level skills he imagines to be genetically determined, and we haven't a clue how they influence them. My late wife was a psycholinguist and thus interested in the way the brain process speech. There were psycholignuists who used magnetic resonance imaging to try to roughly work out what was going on in the brain when it was processing speech, but she didn't think that they were getting useful results.
There are research techniques that work to some extent, but all they tell us is that it is a multi-stage process, and different stages happen in different bits of the brain. "Where" is sort of predictable for most right-handers, but at least one of her colleagues wouldn't look at left-handers, because their processing happens in different areas and the different areas vary from one left-hander to the next.
