@Stagecoach_East I've seen no updates regarding the Fulbourn Road Lane closure since last Thursday - No traffic westwards. Any official statement?

[Dom Murphy @DMurphy101]

@Stagecoach_East Thank you Ivy!

@Stagecoach_East Number 7 bus isn't trackable for the last few days. No time estimates in the app, can't see on the map, and it does not appear on the Whittle Avenue bus stop's or Addenbrooke's info board at all.

[Dom Murphy @DMurphy101]

@Stagecoach_East Stagecoach number 7 service from Whittle Avenue to Cambridge at 9:47am has not shown up. No tracking information on the app for any of the number 7 from this stop. Thoughts?

National Lab (LBNL) results support LK-99 as a room-temperature ambient-pressure superconductor.

Simulations published 1 hour ago on arxiv support LK-99 as the holy grail of modern material science and applied physics.
(https://t.co/UOOtDlx3eE)

Here's the plain-english explanation:
- The simulations modeled what the original Korean authors proposed was happening to their material - where copper atoms were percolating into a crystal structure and replacing lead atoms, causing the crystal to strain slightly and contract by 0.5%. This unique structure was proposed to allow this amazing property.

- @sineatrix from Lawrence Berkeley National Lab simulated this using heavy-duty compute power from the Department of Energy, and looked to see what would happen to the 'electronic structure' of this material, meaning, what are the available conduction pathways in the material.

- It turns out that there are conduction pathways for electrons that are in just the right conditions and places that would enable them to 'superconduct'. More specifically, they were close to the 'Fermi Surface' which is like the sea-level of electrical energy, as in '0 ft above sea-level.' It's believed currently that the more conduction pathways close to the Fermi surface, the higher the temperature you can superconduct at (An analogy might be how its easier for planes to fly close to the surface of the ocean due to the 'ground effect' that gives them more lift.)

This plot in particular shows the 'bands', or electron pathways, crossing above and below the Fermi surface.

- Lastly, these interesting conduction pathways only form when the copper atom percolates into the less likely location in the crystal lattice, or the 'higher energy' binding site. This means the material would be difficult to synthesize since only a small fraction of crystal gets its copper in just the right location.

This is insanely bullish for humanity.

@Stagecoach_East After waiting an hour and 15 minutes, a bus did finally arrive. I complained to the driver (though apologised alongside saying that it wasn't his fault personally). I shall be making a formal complaint through your feedback form on your website.

[Dom Murphy @DMurphy101]

Waiting for an hour at Glenmere Close, Cambridge for a number 3 bus to the city centre and nothing turning up. App is useless as buses just aren't showing up. Terrible service. @Stagecoach_East

Can you call the UK government alert test a success if neither me or anyone in my family got it? 🤔 #emergencyalert

Gordon Moore, thank you for everything.

Each to their own but Harry and Megan are getting far too much media coverage in my opinion. #bbcnews

Oh look, another Citi 3 Stagecoach bus that just didn't turn up. So much for improved network. (Citi 3, Greystoke Road Cambridge stop, to Fison Road, 10:57am arrival according to app) @Stagecoach_East
