How can you predict a volcanic eruption?

Technically Speaking | a science and engineering... ·

2022/09/29

At least twenty volcanoes are erupting as you read this but for many, it's not something we often think about. Laura, Antonia and Ellie discuss animals that live near volcanoes, what you would need to know to predict a volcanic eruption, how likely one is to erupt and whether we'd like to live near one. Just how does the galapagos land iguana sense that their volcano is about to blow?

What is toxic?

Technically Speaking | a science and engineering... ·

2022/09/15

There are loads of things that we eat and drink that can be harmful if you have too much, and lots of ways that plants and animals protect themselves using toxins. Laura, Ellie and Priyanka discuss venomous snakes, and how they differ to poisonous creatures, and talk about what exactly happens in our bodies. What’s the difference between a neurotoxin and chemotherapy? Are apple pips really poisonous? What happens if a venomous snake bites itself? Listen in to find out.

2022/09/01

Trends show that an increasing number of people would prefer to drive cars with an automatic gear box. Is that because they're better to drive or because everyone will be driving electric cars which don't tend to need to change gears? Laura, Rwayda and Antonia discuss current advances in car technology, share their own experience of driving, and speculate about what the future might hold. Will we all be using flying cars in the future? What about self driving cars? And why do cars even need

What is cryptocurrency?

Technically Speaking | a science and engineering... ·

2022/08/18

You hear a lot about it, but what is cryptocurrency, how do you get hold of it and what's it useful for? Laura finds out from Aneeqa and Jennifer what things like blockchain and mining bitcoin are about and how you can own a non-fungible token (NFT). They also discuss whether this decentralised currency is sustainable or if its all really a pyramid scheme. Read more about this in Laura's article.

2022/07/21

With the expense of the James Webb Space Telescope and the ever worrying climate emergency, we're wondering what the benefit of space travel and space exploration is. Ellie, Antonia, Laura and Emma discuss this from the point of view of climate science, discovery, collaboration, what inspired us to become scientists, and space tourism. We talk about what the future might hold. What would you do if you were in charge of a planet's space programme? Read a summary of this episode here.

Technically Speaking | a science and engineering... ·

2022/06/15

Our research for the episode on a house that stores electricity involved some kinda weird-yet-strangely-compelling conversation and we've pulled the best bits together! Antonia and Chris discuss many reasons why a cement-based battery is safe to handle, review research into wearable devices and energy harvesting, and question what the future might hold.

Can you build a house that stores electricity?

Technically Speaking | a science and engineering... ·

2022/06/02

A recent discovery got the team speculating about the future. Laura, Antonia and Rwayda take a look at research where cement is made to store electricity and wonder whether this material could be used to build our future homes. How much electricity can it store and what can it power? Is there a futuristic way of using that power without the need for cables? What's next for this laboratory discovery?

What is sustainability?

Technically Speaking | a science and engineering... ·

2022/05/19

It's a buzzword that comes up a lot in food, transport, energy, and other industries. Laura and Antonia discuss what sustainability means and why its not so easy to decide whether something really is sustainable. Although some aspects of sustainability can be measured, others are more of a philosophy which depend on the society and environment you're working in. The team digs into a real-life example that compares digital books to printed ones to illustrate how challenging it is to demonstrate

Are there any benefits of ionising radiation?

Technically Speaking | a science and engineering... ·

2022/05/05

Radiation is all around us; we're all slightly radioactive! Ellie, Emma S, Laura and Priyanka talk about how radiation is used in medicine to treat cancer and how the body can repair damage to healthy cells. They also discuss how it's used in materials science, how it can help control mosquito populations and preserve food. Some wild speculation also considers how we could all become X-men and develop useful characteristics of animals. Read about some specific examples of radiation in medicine.

Technically Speaking | a science and engineering... ·

2022/04/21

Humans have been shaping the environment for decades, and so have other species. When humans do it, it often has some negative, unintended consequences. Laura, Ellie and Antonia discuss some invasive species that were intriduced to Australia and what was done to try and manage the effects along with the battle of grey versus red squirrels in Victorian England and the lasting effect that it has had. Conversely, where a species has been completely removed from an environment, the team also discusses

What can materials science learn from nature?

Technically Speaking | a science and engineering... ·

2022/04/07

The natural world has evolved to give us some really cool stuff, stuff that inspires us to make better materials. Laura and Ellie discuss some of their favorite materials that mimic something from nature as well as some machines and other devices that are inspired by nature. They also speculate on what adaptations they might want, including retractable claws and something inspired by the Aliens movies. The team discussed adaptable thermal insulation that is inspired by squid skin. Read abut this

2022/03/23

Following on from the episode about the electricity grid, Aneeqa, Jennifer and Laura discuss how two types of solar cells, also known as photovoltaics, are made and how they work. The ability of these devices to convert sunlight into electricity should mean they're perfect for tackling climate change so the team also asks how sustainable they are to make and recycle, how long they last, and whether they produce enough electricity for our needs. The points made in this conversation helped Laura

What don’t we understand about electricity?

Technically Speaking | a science and engineering... ·

2022/03/10

The UK's electricty grid started development about 100 years ago and originally accommodated steam driven turbines that are controlled by people. Ghalia, Antonia and Laura discuss whether the electricity grid can work with electricity generated from intermittent sources (like wind and solar) alone and what adaptations are being developed. They also struggle to remember lessons from high school about electricity, and provide insight from their careers which involve water engineering, energy analysis
