Flight simulation of a harrier jump-jet

Harrier aircraft flight simulation. Supercomputer image of a Harrier aircraft hovering over a runway in a virtual wind tunnel. The lines beneath the aircraft show the air flow from the aircraft's engine. The lines colours show the air's tempera- ture gradient, from red (highest), through orange, yellow, green, and blue, to purple (lowest). The Harrier is a Vertical Take-Off and Landing (VTOL) fighter aircraft which directs air from its Rolls- Royce Pegasus engine through 4 swivelling nozzles along the side of its fuselage. The nozzles point downwards for take-off, before rotating backwards to accelerate the aircraft into wing-borne flight

Fruiting bodies of Rhizopus oligosporus

Rhizopus oligosporus fungus. Coloured scanning electron micrograph of fruiting bodies and spores of the fungus Rhizopus oligosporus. The fruiting bodies consist of globose sporangia containing large numbers of sporangiospores (small round). Each sporangia is supported by an upright aerial hypha called a sporangiophore (stalk-like). Rhizopus is an important fungal species in food production as it manufactures the essential amino acid tryptophan. R. oligosporus is used in the production of tempeh", a solid fermented meat substitute made from soya beans. Magnification: x140 at 4x7cm size. x500 at 9x5"
