Karl Popper (1902-1994) is regarded as one of the greatest philosophers of science of the twentieth century. Alan Saunders presented this portrait of Karl Popper for The Science Show in January 2001.

A weekly injection that stops that hankering for hot chips and donuts?Many people on Ozempic and similar medications report this phenomenon, saying they no longer have incessant thoughts about sweets and fried food.So how do these drugs, known as GLP-1 agonists, work in the brain to dial down "food noise" and help people lose weight?

The overland telegraph connecting Australia to the world was completed just over 150 years ago. It was built due to the dedication of a public servant, Charles Todd.

It's the size of a sesame seed, but it could cause unfathomable destruction to Australia's forests and urban canopy.A beetle called the polyphagous shot-hole borer (Euwallacea fornicatus) is silently spreading through Perth and its surrounds, forcing councils to chop and chip hundreds of trees — even century-old Moreton Bay figs.So how does the tiny pest cause such massive problems?

Roger Short (1930-2021) discusses influences in his early life, and some of his research achievements including melatonin as a controller of circadian rhythms, and aspects of reproductive biology across the animal world.

First they learnt how to flip open wheelie bin lids. Now they're using water fountains.Masters of the urban landscape, sulphur-crested cockatoos (Cacatua galerita) are more than capable of some quirky (and sometimes messy) antics.So what do these entertaining exploits tell us about cockie innovation — or even cockie culture?

Get ready for gravitons, dark photons and transition states. Kathryn Zurek takes us on a tour of the bewildering world of quantum physics.

A couple of months ago, a killer started mobilising off the South Australian shore — one that would wipe out marine life, make surfers feel sick, and smother picturesque beaches in thick foam.The culprit? A bloom of tiny organisms called microalgae. We can't see them with the naked eye, but in big enough numbers, they can devastate ecosystems.So what made the South Australian algal bloom so lethal, and can anything be done about blooms like it?

People have been in the Australian wilderness for generations. But can people be considered part of the natural landscape or will they always have an impact?

If you were impressed by generative AI such as ChatGPT, then artificial general intelligence or AGI promises to really knock your socks off.Over the past couple of decades, tech companies have been racing to build AGI systems that can match or surpass human capabilities across a whole bunch of tasks.So will AGI save the world — or will it spell the beginning of the end for humanity?

She could only read and write from age 10. She reared children and had a first unsupportive husband. But Mary Somerville was able to correct the work of Isaac Newton, help discover Neptune, and write a science book which became a university text.

The next time you pick up a bag of spuds from the supermarket or fill up the car with petrol, you can thank the Treaty of the Metre for the metric system that underpins daily life.The treaty was signed exactly 150 years ago, when delegates from 17 countries gathered on a Parisian spring day to establish a new and standardised way of measuring the world around us.But the metre's inception predates the treaty that bears its name by nearly 100 years. So how did it come about, and how has its definition changed over the centuries?

Amateur fossil hunters make a major discovery. And Marilyn Renfree describes the sophisticated reproduction of marsupials.

Southern right whales (Eubalaena australis) were named by whalers because their high oil content made them the "right" ones to kill.In the decades since whaling was banned, southern right numbers increased — but a new study shows that population growth stalled, and might've dropped a bit, despite current numbers still far below what they were in pre-whaling times.So what's going on with the southern rights?

David Walker at UCLA says he can halt aging in fruit flies. Can the same concepts be applied to humans? And two tertiary students and an artist describe combining science and artistic pursuits.

Cobras, taipans, black mambas — Tim Friede's been intentionally bitten more than 200 times by some of the most venomous snakes on Earth.And he survived, mostly because years of self-injecting venom let him develop immunity to them.(Please do not try this yourself!)Now his blood's been used to make a broad-spectrum antivenom that researchers say may protect against nearly 20 deadly snakes.But this is not how antivenom is usually made. So how are snake antivenoms produced, and where are we with a "universal" version?

Sir Mark Oliphant of Adelaide was the main person missing from the film Oppenheimer. It was Sir Mark who carried the letter from European scientists to New York to convince the American President that Hitler was trying to make an atomic bomb and needed to be beaten to the chilling quest. It led to the Manhattan Project.Mark also gave us microwave power, initially to equip planes, later to give us microwave ovens; he helped establish the ANU; was the first President of the Australian Academy of Science and became governor of South Australia.He was the 'right hand man' of Sir Ernest Rutherford of NZ who revealed the atomic nucleus and won the Nobel Prize in 1916. It is often reported that they "split the atom" and so enabled the incredible power therein to be released. It was this, as well as the Manhattan Project, that made Sir Mark Oliphant such a voice for peace and tolerance, as this Science Show from 1986 remembers.

The Australian overland telegraph was a 3,200 km line connecting Port Augusta in South Australia to Darwin. It was completed in 1872 and allowed communication between Australia and the rest of the world. It was one of the great engineering feats of 19th-century Australia and was a significant milestone in Australia’s development. The line was built due to the determination of one man, a government employee, Charles Todd. As we celebrate 150 years since the line was completed, Sharon Carleton looks at the Charles Todd story, who it turns out was the first pioneer of STEM, way before the acronym had come into use.

In the final part of his series on the connections between developments in physic and music, the late Ian Johnston, physicist from The University of Sydney, explores developments in the twentieth century. In physics, communications technology saw valves come, and go, replaced by transistors, then silicon chips, leading to increased capacity and miniaturisation. In music, accepted conventions of harmony came under attack and composers experimented with more freedom. Musical styles developed using new electronic instruments offering new sounds and capability. In the end, Ian Johnston says the desires of music and physics are the same – both search for harmony.

In the nineteenth century western music moved from classicism to romanticism, and our knowledge of physics progressed in electricity, electromagnetism and the wave properties of sound. We also began to understand how the ear and brain work allowing us to perceive and appreciate music.
