...energy because this sugar is made up of ‘simple’ carbohydrates. But some fruit, like bananas and apples, give you long-lasting energy because they contain ‘complex’ carbohydrates. Sweets and syrup taste good and give you a quick boost of energy because they contain sugary simple carbohydrates which are burnt up quickly by our bodies. The problem is sweets and...

Working with our environment: an introduction

...energy and materials to all ecosystems. It is, then, difficult to make a clear distinction between a 'managed environment' and a 'natural ecosystem', although we can all understand the difference in principle between planned management and inadvertent change. Not only are we part of nature, but, as Figure 1 suggests, we exert an increasingly dominant influence on our...

Animals at the extremes: hibernation and torpor

...energy-efficient survival when ambient temperatures are so low that foraging or simply maintaining normal core body temperature and basal metabolic rate are either energetically too costly or impossible. Polar endotherms can maintain a high T b even when living actively at sub-zero temperatures. Such animals have very good thermal insulation and may have a plentiful food...

The formation of exoplanets

...Solar System. These include ‘hot Jupiters’ orbiting very close to their parent star and rocky ‘super Earths’ many times larger than our home planet. In this free course, The formation of exoplanets, you will learn about the challenges connected with efforts to reconcile the observed exoplanet population with current theories on how planets form. The two main...

...energy, which cannot be created or destroyed. It is Noether's theorem that relates this conservation law to the underlying symmetry of space itself – in fact, the conservation of energy is a result of the fact that empty space 'looks the same' from one moment to the next. Put another way, if empty space were rough or lumpy, then energy would be lost as things moved...

Retrofitting older buildings to help mitigate the climate emergency

...energy demand and associated carbon emissions is, therefore, a key strategy that has been highlighted by the UK Committee on Climate Change and is acknowledged in the Government’s recent heat and buildings strategy. However, 20-30% (that's over ten million homes) of the UK housing stock have heritage value. Many of these buildings aren’t officially designated, meaning...

...energy to do so, leaving less energy for growth and reproduction. Consequently, they up smaller in size. Aside from the impact this has on shellfish, several of the species affected, such as corals in the tropics or coralline algae in the waters around the UK, also play a key role in providing food and nursing grounds for fish. And less fish food leads to fewer fish for...

...energy and loss of interest in an activity. Secondly, feelings of low personal accomplishment and low self-esteem leading to a decrement in performance. Thirdly, depersonalisation and devaluation, where an individual starts caring less about their sport and what was originally important to them. Keep on running!
