THE win­ners of this year’s No­bel Prizes have been an­nounced. Named af­ter Swedish chemist Al­fred No­bel, ev­ery year the awards hon­our peo­ple who have ex­celled in six cat­e­gories – three of them re­lated to sci­ence. The oth­ers are the No­bel Peace Prize, the No­bel Prize in Lit­er­a­ture and the prize for Eco­nomics.

The No­bel Prize in Physics

Win­ners: Rainer Weiss, Barry C Bar­ish and Kip S Thorne. Th­ese three Amer­i­can sci­en­tists won for mak­ing the first ob­ser­va­tions of grav­i­ta­tional waves, which are rip­ples in the fab­ric of space-time that were first pre­dicted by leg­endary sci­en­tist Al­bert Ein­stein.

The No­bel Prize in Chem­istry

Win­ners: Jac­ques Dubo­chet, Joachim Frank and Richard Hen­der­son. The team won the £830,000 prize for their work in cryo-elec­tron mi­croscopy. This type of mi­cro­scope tech­nol­ogy al­lows sci­en­tists, for the first time, to record bio­chem­i­cal pro­cesses as they hap­pen – a de­vel­op­ment that is rev­o­lu­tion­is­ing bio­chem­istry (the sci­ence that stud­ies chem­i­cal pro­cesses that oc­cur within liv­ing things).

The No­bel Prize in Phys­i­ol­ogy or Medicine

Win­ners: Jef­frey C Hall, Michael Ros­bash and Michael W Young. The prize for medicine was awarded to a team that made dis­cov­er­ies about the 24-hour body clock. They found out how plants, an­i­mals and hu­mans adapt their bi­o­log­i­cal rhythm so that it is syn­chro­nised with the world around them.
