Science & Nature

Our bodies are designed to fight disease, and food can be used to amplify this hidden power. In this conversation, Dr William Li reveals how what we eat can help reduce the risk of dementia, cancer and other avoidable diseases.

Yes, earworms are annoying, but have you ever stopped to think what they reveal about our brains? They are the price we pay for an astounding relationship our minds and bodies share with music that lasts our entire lives.

Cognitive neuroscience is pushing boundaries and is now able to pinpoint specific signatures of the brain, differentiating between nuanced emotions like how we experience awe and beauty - vastly complex feelings that, until now, have been out of reach.

We have all used one of those little compasses to find out which direction is North. But what makes those needles move is something much bigger and essential for making life on earth possible. What is it and why do we need it?

The basic truth of dieting holds true, to lose weight, you have to burn more energy than you eat. What role do our genes play in influencing what we like to eat? And what affect do genes have on body weight?

When thinking about volcanoes, you are probably imagining an enormous mountain with some fumes on top of it. But 80 percent of the volcanic eruptions on Earth take place in the ocean. Why are underwater volcanoes so active?

Psychedelics might have unique qualities that can foster our inner creativity. But exactly what hidden mechanisms can these drugs unlock in our brains? and could we replicate these effects without taking these drugs?

If you inherit your genes from your parents do they determine your entire life? Genes are the building blocks of life and as technology in gene editing  intensifies can or should we change our genes?

We all know that genes provide the blueprint for life. They're the code written into our DNA, but can they also predict our future? What can we learn from our genes? 

Our solar system has anomalies. Astronomers suggested the existence of a hidden giant planet as a plausible explanation. The problem is that we have never been able to see this planet. Is our math wrong or are we really missing something?

What jumps to your mind when thinking about creativity? Chances are it wouldn't be maths. Philosophers, scientists and mathematicians used creativity to solve seemingly impossible problems. Could maths actually be as creative as the arts?

We are all surrounded by an unseen, invisible world; a world made of mysterious substances that we can’t see or touch: the Dark Universe. But if we can’t see it, touch it, or detect it, why do we think it is there?

400 million years after the Big Bang, the Universe was very different from what it appears today. At that time (around 13 billion years ago) the universe was dark and empty. But how can we know that? Is there a way to travel back in time?

Professor Sara Seager is a pioneer in vast world of exoplanets & the search for other life in the universe. In this Garden Talk, Sara will consider space science's biggest question: Are we alone in the universe?

Insects are the most numerous species on Earth & play a critical role in the health of our ecosystem. But insect populations are on the decline. Are we approaching an insect apocalypse & can we reverse this trend?

Sharks are often one of the more misunderstood creatures of the sea, for years demonised by movies. This talk explores why sharks are in fact an essential part of the ocean's ecosystem and how our own future is dependent on saving them.

Today, nuclear energy provides close to 10% of the world's electricity and has the potential to shift reliance on fossil fuels. But is nuclear really clean energy? Are the potential risks worth the benefit to the world?

Agriculture has been at the centre of civilisation for thousands of years. However, when we shop for our food, have you wondered about what developments have led to the food getting on our plates.

Some of mankind's most enduring questions are about who we are as individuals, how we can live successfully alongside others, & the tension between the two. What can we learn about identity from our furry, feathered and scaly friends?

The world of dating, sex and childbirth is a hazardous one, full of complex behaviours and even threats to our health. Well, mating in the animal kingdom is just as complex. What can we learn by looking at our animal cousins?

How we eat and the impact it has on our bodies, from weight loss and weight gain to eating disorders, is complex and a key facet of human health. But most of these behaviours and conditions aren't unique to our species. What can the animal world teach us?

We often think of plants as organisms left on their own to survive. Seemingly still and unable to make any noise they managed to fight with the rollercoaster of evolution. But plants talk to each other. So, what do they talk about?

Climate change is resulting in ever-more intense weather events of all kinds, from heat waves and forest fires to hurricanes and floods. If extreme weather becomes the new normal, can we survive it? And if so, how?

Plants wouldn’t have made it out of the water 450 million years ago if not for their collaboration with fungi. They are an ancient and extraordinary kingdom that exists everywhere. But if fungi are so essential, why are they so easy to miss?

We could not exist without flowering plants, but to this date researchers cannot explain where they came from. Why did Darwin describe the origin of flowering plants as an “abominable mystery”?

When it comes to love, all the mystery, all the poetry and all the complex behaviours that lead to the most life-changing decisions we’ll ever make are driven by just a few molecules in our brains. What's the science of attraction, and can we fake it?

Humans aren't unique in having an adolescent stage, but we are pretty unique in how we react to it. Why do other species find it easier to surf the trials and turmoils of this challenging life phase than we do?

Until relatively recently in human history, there wasn't a word meaning "blue". Of the ancient cultures, only the Egyptians had a word for this colour. What was everyone else seeing?

Colour is an experience: the colours we see and what they mean to us will differ for every human on the planet. What can art history, science, anthropology, literature and politics teach us about colour?

More than 75% of sea creatures produce their own light. How do they do it, and what can we learn from this incredible marine firework display?

We know so little about the deep sea, and even less about what it's like beneath the ice of the Earth's polar regions. How does life flourish in one of the most inhospitable environments on the planet?

There's so much left to learn about the sea and its organisms. Could the ocean be the source of the next drug to change medicine?

The tech required to explore the deepest parts of the ocean is coming on in leaps and bounds. What bizarre habitats and organisms have we found, and what still remains to be discovered?

The oceans absorb nearly 1/3 of our carbon emissions; they are literally the world's lungs. How does the sea 'breathe', and why does it do it?

DNA is the go-to forensic evidence in many criminal cases. What other trace evidence can be used to identify the perpetrator when they don't leave DNA behind?

The most transformative scientific breakthroughs depend on maths. Which problems are mathematicians working on that will drive scientific change in the coming decades?

As the science improves, we can detect smaller and smaller traces of DNA. Does that mean we could pin someone to a crime scene who was never there at all?

We think of forensics as a science - dispassionate and objective. But can we say the same about the humans who interpret it and decide what it means?
