Live coverage from the NatWest Trophy quarter-final match between Yorkshire and traditional rivals Lancashire. This year, Lancashire are on course for that unprecedented clean sweep of all four domestic cricketing trophies that so narrowly eluded Warwickshire last year. Plus, regular roundups from the other grounds. Warwickshire will play Derbyshire, for whom the competition represents the only hope of success in what has been a dismal season, while championship contenders Northamptonshire have put aside poor one-day form to earn a tie against Gloucestershire. Meanwhile, Middlesex face a difficult game against Glamorgan at Cardiff. Introduced by Tony Lewis.

Third of a six-part magazine series investigating the relationship between science and modern society.

Research implies that 10,000 people could be dying from the traffic pollution in Britain each year. Presenter David Malone discovers that Britain has just seven EU-approved pollution measuring sites, compared with Germany's 200, and that there are no national standards for ozone or nitrogen dioxide levels. Will Britain have to follow the example of smog-filled Athens, where residents wear face masks in the summer?

He also investigates the environmental row between Greenpeace and the chemical industry over chlorine, the basis of some of the most common chemicals in the world. Some feel it may be the cause of decreasing fertility in men, as sperm counts have halved since the Second World War.

Finally, David meets philosopher Ed Regis to talk about the science of nanotechnology. Scientists can now write the contents of four encyclopedias on a pin. How far will nanotechnology be able to transform human society?

How would you feel if someone had sex with you knowing that they might give you Aids? In the US, a man was convicted of attempted murder in for doing just that.
There are those within British Aids organisations who refuse to condemn people for risking the infection of others, on the grounds that people who are HIV positive already suffer harassment and discrimination - to be told it is wrong to have sex which risks passing on a life-threatening virus would be simply offensive. Other activists disagree, and feel that people who are HIV positive or have Aids should show more responsibility in their sexual behaviour. New research suggests that a substantial number of people are failing to do so. Mark Easton reports on the controversy and examines the argument that Britain should make such behaviour illegal, and talks to those whose lives have been affected.

The misery in the aftermath of the atomic bombing of the Japanese city Nagasaki is evoked by three stories told from different points of view.

The first story tells of Sumiteru Taniguchi, a 16-year-old postman who was delivering mail on his bicycle when the bomb exploded. With the aid of contemporary footage of Mr Taniguchi and archive film of him in hospital - shot by US Army doctors in 1945 - it shows how he and his family were psychologically affected by his injuries.
The second tells of US Marine Victor Tolley, who came ashore in Nagasaki harbour with his fellow sailors, six weeks after the bombing. Marine cinematographers filmed the occupation, including encounters with Japanese survivors.
Finally, the programme tells of Isuko Okubo, who searched in vain for her son Akira after the blast. He had been attending classes at the medical school, which was destroyed.
In addition to recently discovered rare footage from 1945, Nagasaki Journey features black and white still photographs, taken the day after the blast, by Japanese Army photographer Yosuke Yamahata.
