How do you work out how safe or dangerous a chemical or some other substance is? This week's Risk Bites takes a look at chemical safety, and estimating health risk from chemical exposure. This week's Risk Bites team: David Faulkner (post-production) Andrew Maynard (all the other stuff) Risk Bite
How do you know if the chemicals in the stuff you use and eat are safe? Only a small fraction of the thousands of chemicals in use today have been thoroughly tested for safety. Part of the problem is that how we test chemicals now is slow, expensive, and relies an awful lot on animal testing. How
A hormone is a chemical messenger that is secreted (or released) into our bloodstream by specific organs known as glands. Hormones regulate (or control) many processes in our body, including blood glucose levels, water content in blood, general growth, and blood pressure – just to name a few. They
What are viruses | Cells | Biology | FuseSchool In this video we are going to look at what viruses are. Viruses are a type of microorganism. They are too small to be seen with the naked eye: much smaller than bacteria, and about 100 times smaller than human cells. They come in many different shape

As populations have grown, farming practices have become more intensified to maximise crop yields and ensure we can feed the ever growing population. Fertilisers and pesticides are used on crops, and animals may be kept inside in more densely packed sheds to maximise milk yields, or egg production,
What does diabetes mean to you? Something to do with sugar right? Would you be shocked if I told you that every 6 seconds someone dies from diabetes? One in 11 adults worldwide has diabetes, with 1 in 2 not being diagnosed. So it is important that we all know what it is, how it can be detected and

In this video we look at a few keys words that you will come across throughout ecology. An ecosystem is made up of all of the communities that live in it, every single organism from small to big and lots of environmental factors like sunlight and shade in the woodland, streams and other things. It
In terms of biological classification, organisms are classified, or grouped, with other organisms that they are most closely related to. These small groups are then classified together into larger groups and so on, until we reach the top level of classification which places organisms in one of thr
Photosynthesis is a chemical reaction that is fundamental to life. In this video we are going to have a look at the factors that affect the rate of photosynthesis. There are 3 main factors: light intensity, carbon dioxide concentration and also temperature. These factors are called limiting fact
