With ever growing pressures on the environment, caring for our land is become urgent. In this interview with Rod, Tom Baker from Landcare gives a sense of the breadth of work that organisation performs.

There are a few ways to get involved:

• Landcareact.org.au the landcare Calendar for activities in your area.
• Parkcare Hub at parks.act.gov.au to work on a patch with Rangers, assist the Wildlife Team in managing wildlife or volunteering to work with park visitors. Ph 62057384.
• Friends of Botanic Gardens

Did you know Fuzzy Logic is one of Australia's longest running science radio shows? Its heritage is a bit misty, but we do know that 2XX was broadcasting The Science Program in May 1981.

In this interview, one of the earliest station technicians, Kimmo Vennon describes those early days. Recorded by Rod from the tower in Canberra where 2XX first broadcast in 1976. The building nearby housing communications equipment was destroyed by probable arson in 1988.

That tower dates back to 1928, making it a historical artefact, especially significant because it's a rare example of a free-standing radio tower. As Kimmo tells us, there's a surprising amount going on under the ground at this site.

Is your memory like something that can recorded and retrieved on magnetic tape? No. We can discard that as an extremely poor analogy.

Our guest on Fuzzy Logic today is an expert on how memories are laid down and recalled. It's a subtle, complex thing with many facets that we don't entirely understand. For one thing, there are different types of memory, and it's far from an immutable record. It has links to autism and PTSD, among other things.

We discuss the recent pronouncements from the USA about Tylenol 'causing' autism. Official Fuzzy Logic policy states that we support critical thinking, which means we strongly reject assertions made without evidence, especially where they relate to public health.
