This is good news for a few reasons. Figuring out exactly which one to buy can be a pain: Incandescent bulbs are cheap, but burn out easily. CFL bulbs, the weird curly things that’ve become popular in recent years, are brighter and last longer. However, they take long to warm up and use poisonous chemicals like mercury to generate light. LEDs last the longest and use the least amount of energy, but they’re also the most expensive. Now, thanks to General Electric, it will be a little easier to sort through the options.

Quark
Quarks are subatomic particles considered one of the building blocks of all matter. They were discovered in the 1960s by the US physicist Murray Gell-Mann, who originally called them quorks until he came across a bizarre line in Joyce’ Finnegan’s Wake: “Three quarks for Muster Mark!” Noting that quarks can cluster together in threes to form other subatomic particles called baryons, Gell-Mann changed the name from quork to quark and credited Joyce with the name.
