2022-06-0224 minTechnically Speaking | a science and engineering discussionWhat is sustainability?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 sustainability.
This special episode might also have a record number of references to previous episodes. How...
2022-05-1935 minTechnically Speaking | a science and engineering discussionAre there any benefits of ionising radiation?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.

2022-05-0533 minTechnically Speaking | a science and engineering discussionHow do we deal with invasive species and repopulation in the natural world?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 how they can be carefully reintroduces and the consequences that beavers could have as environmental engineers. It...
2022-04-2138 minTechnically Speaking | a science and engineering discussionWhat can materials science learn from nature?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 here.

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 decide whether she would get solar panels and you can read all about it.
2022-03-2327 minTechnically Speaking | a science and engineering discussionWhat don’t we understand about electricity?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 and particle accelerators.

The weather forecast isn't always so accurate though. Ghalia, Aneeqa, Jennifer and Antonia discuss what weather predictions mean for transport, heating and air conditioning (AC) and why it may not always be accurate. Ghalia explains how the water industry needs to forecast the weather decades into the future so that agriculture and sanitation can be supported while Antonia references how renewable sources of electricity are dependent on wind and gas.
