![Genetically engineered tomato plants. Geneticist Dr Virginia Ursin examines cultures of Flavr Savr tomato plants; the first genetically engineered whole food. Each dish contains seedlings cultured from a single cell, grown on agarose medium. Flavr Savr tomatoes have a gene that allows the fruit to ripen on the vine without softening; so they are tastier, don't need ripening with ethylene gas, and are not damaged during shipping. Tomato softening occurs due to the enzyme polygalacturonase. Flavr Savr tomatoes contain an anti-sense gene that blocks the enzyme. This tomato entered American supermarkets in 1994 but was withdrawn from the marketplace by Monsanto (which bought Calgene in 1997). Research at Calgene, California, USA. MODEL RELEASED [1995]](https://m.psecn.photoshelter.com/img-get2/I0000jdQAv1Zvelk/fill=/fit=180x180/I0000jdQAv1Zvelk.jpg)

![Physics: Scientist, Cynthia Alviso, with two organic aerogels. The cloudy white disc is silica aerogel, whilst the red disc is an aerogel containing fibers of an organic material. Aerogel is a new material, which has very high thermal insulation and extremely low mass. It is made by drying a water-based or alcohol-based gel in a super fluid process that prevents the gel from collapsing. The resulting block of linked microscopic fibers contains about 90% air, so is very lightweight. Aerogel is being studied as a thermal insulator and as a holding medium for nuclear fusion fuel. Photographed at the Lawrence Livermore National Laboratory, USA. MODEL RELEASED [1991].](https://m.psecn.photoshelter.com/img-get2/I0000hqbklEdXBk8/fill=/fit=180x180/I0000hqbklEdXBk8.jpg)
![Physics: A blowtorch is applied to a sample of aerogel to demonstrate its insulation properties. Aerogel is a new material, which has very high thermal insulation properties and extremely low mass. It is made by adding alcohol to a conventional silica gel to remove water. The gel is then placed in a pressure chamber, and the alcohol removed under super fluid conditions. This prevents the gel from collapsing. The resulting block of silica fibers contains about 90% air, so is very lightweight. Aerogel is being studied as an insulating material and as a holding medium for nuclear fusion fuel. Photographed at the Lawrence Livermore National Laboratory, USA.
