First observation of omega-minus particle
This historic photograph from the 80-inch (200cm) bubble chamber at the Brookhaven National Laborat- ory shows the first observation of the omega-minus particle, which consists of three strange quarks. A negative kaon enters at bottom left & collides with a proton in the chamber's hydrogen to produce 3 particles, including the omega-minus. The omega travels a short distance before decaying into a negative pion, which veers to the right across the bottom part of the picture, & a neutral xi partic- le which leaves no track. Discovery of the omega in 1964 confirmed Gell-Mann & Ne'eman's classific- ation of subatomic particles, the 'Eightfold Way'.

Square tomato. Conceptual image of a tomato that has a cuboid shape. This could represent a tomato that has been genetically modified to form this shape to allow more efficient packaging and easier slicing. Genetically modified (GM) tomatoes are commercially available, but are still round. Such changes in shape can also be achieved by growing the fruit in a suitably shaped container. Genetic modification is the alteration of an organisms DNA (deoxyribonucleic acid) to create inherited changes. For food crops, the changes can include improved shelf-life and resistance to disease.
