A busy week has meant a pretty poor showing on Just A Theory, but hopefully a packed roundup will make up for it:

LHC a-go-go

The Large Hadron Collider is finally up and running again! As our CERN correspondent Emma mentioned last month, scientist in Geneva have been working on restarting the LHC after it had to be shut down last year. Their hard work paid off on Friday, and proton beams are now successfully colliding in the 27km-long ring of the world’s largest experiment. Now for the science!

What if the Earth had rings?

Speaking of rings, check out this short video showing how it would look if Earth had its own set, like Saturn.

At the equator they appear to be a thin line through the sky, but further north or south they make an amazing sight, lighting up the sky even at night. Anyway we can build these things and cover them in solar panels or something?

Field less players to win the World Cup

It seems that having a large squad to choose from can actually be a hindrance when it comes to top football. You might think fielding substitutions lets mangers pick the best players for every situation, but research shows that sticking with the top 11 is the key to success.

Bacteria that can detect landmines

Scientist at the University of Edinburgh have developed a strain of bacteria that glow green near explosives. By mixing them with a colourless solution, they can be sprayed from the air on to suspected landmine fields, turning the ground green if mines are detected.

  2. Just a wee bit of a correction on the CERN front….

    Over the weekend there has been a beam circulating around the LHC with good lifetimes (about half an hour). There has also been an anti-clockwise beam making its way around the ring too. However, as yet there have been no collision! At the moment, the goal is to lengthen the lifetime of the beam to an ideal 10-12 hours in the ring.

    There have been some events recorded, but these are splash events (caused by a beam exiting the ring and hitting a ‘stop point’), or data taken from the beam passing though the detectors, not from collisions yet.

    The first collisions are likely in the next week or so (hopefully before I leave) and as I said in my post last week, what CERN classifies as ‘first physics day’ when there will be fairly high energy collisions will be probably around February next year.

    That said, there are loads of cool pics and videos to check out at the moment on the CERN website, and eveyone’s pretty excited over here – many of my mates have been here all weekend working and watching!
