The word pandemic comes from Greek and means “pertaining to all people”. At the end of 2019, the infectious disease covid-19 was discovered. It then spread all over the world, which had enormous consequences for millions of people. In this educational clip, we go through what characterizes a pandemic. You will learn about known pandemics such as the Great Death, the Spanish flu, the Asian, the Hong Kong flu and the swine flu. You will also learn concepts such as infodemias, as well as the importance of credible sources in times when false rumors spread quickly. Show Less

Forming part of the nervous system, the eyes are complex organs responsible for receiving light from the environment and conveying this information through nerve signals to the brain.

With a team including a chef, chemist and dietician, this fun and fascinating 2-part series take a closer look at the foods we all love, with some surprising results. Exploring the latest scientific research behind how they are grown, processed or cooked, the series illustrates that understanding how food works can help us eat healthier (and tastier!). The first episode profiles a variety of one of the world’s most popular fruits, the banana, currently under threat of extinction from a fungal disease. Visiting the scientists cultivating new varieties of disease resistant bananas, it appears that the perfect combination of flavour and texture is within their sights. The traditional craft of fruit preservation is supersized in the production of canned baked beans – and the team uncovers whether or not the process can actually increase the nutritional value of some canned goods. Physics and biology come into play in the science behind cooking the perfect medium-rare steak. A world of cascading chemical reactions is unveiled in a revolutionary new experiment that looks at how to get the flavour and texture of your steak just right. Show Less

With a team including a chef, chemist and dietician, this fun and fascinating 2-part series take a closer look at the foods we all love, with some surprising results. Exploring the latest scientific research behind how they are grown, processed or cooked, the series illustrates that understanding how food works can help us eat healthier (and tastier!). In the second episode, cutting edge science helps us to freeze fish so that they taste almost as good as when fresh. To see how far technology has come, a panel of sashimi lovers are subjected to the ultimate taste test: to see if they can taste the difference between fresh and cryogenically frozen kingfish. The scoop on why humans are hard-wired to desire junk food could be answered by the gelato-making process and a simple, mathematical formula. A specific ratio of carbohydrates, fats and salt can deliver the ‘bliss point’, targeting our brains’ reward system, and releasing the endorphins that makes us feel good. In stunning vineyards, sparkling wine is put under the microscope in the hope that every year will deliver a good vintage, and the chemistry of different hot and spicy foods provides some startling insights. Finally, a better understanding of some unusual crops could see them become the supermarket produce of the future. Show Less

The Great Southern Reef is dominated by a canopy forming seaweed species, Ecklonia radiata. This kelp, sometimes called common kelp or golden kelp is known as a foundation species as it provides food, shelter and habitat for hundreds of species. Seaweeds also play an important role in slowing climate change by taking carbon out of the atmosphere. Show Less

Every year SARDI aquatic sciences send a team of scientists to Pt. Lowly SA, to assess the population of the Giant Australian Cuttlefish aggregation. Divers swim 50m transects counting the cuttlefish to calculate how many animals per square meter there are. On a single transect they can count hundreds of cuttlefish. In the late 90s the population estimate was around 180,000 and appeared stable. In 2005 the population decreased a little, but from about 2009 onwards the scientists started to see a concerning reduction in the population, dropping to just 13,000 animals in 2013 - less than 10% of earlier estimates. Many questions were raised about what was causing that decline. Was it pollution, disease, aquaculture, fishing? Because the area is highly utilised by many different people and organisations, there was a lot of speculation. Scientists tried to assess each potential driver, but did not find a clear link or relationship to any one driver in isolation. Show Less

Giant kelp (Macrocystis pyrifera) are an iconic canopy forming seaweed that can grow over 35 metres long and up to half a metre each day. Like trees in a forest, giant kelp modifies the environment and the resulting conditions favour a huge diversity of other species. Dr. Cayne Layton from the Institute for Marine and Antarctic Studies explains his research on restoring Australia's giant kelp forests. Cayne and his team are examining selected individuals from a range of these remaining populations to examine how warm tolerant their offspring are of warmer water. Show Less
