...carbon nanotubes to complex protein-based molecular motors. Activity 2 (example) Which is the larger distance in each of the following pairs? a.2000 mm or 1.8 m b.1 mm or 1 km Answer a.2000 mm is 2.000 m, which is larger than 1.8 m b.1 mm is 1/1000 m whereas 1 km is 1000 m, so the kilometre is larger. Activity 3 (self-assessment) a.Which is the larger distance in each of...

Starting with maths: Patterns and formulas

...footprints from prehistoric human civilisations have been found preserved in either sand or volcanic ash. From these tracks it is possible to measure the foot length and the length of the stride. These measurements can be used to estimate both the height of the person who made the footprint and also whether the person was walking or running by using the following three...

...footprint’. Your digital footprint is the data that you leave behind when you engage with the internet; this can be social media ‘likes’, posts, pictures or email. In other words, we have some information about us on the internet; this could be something as simple as email, online purchases or social media accounts. Health and social care professionals have to make...

...and other carbon sinks. The delegates at the conference will be discussing ways to better prepare for and create warning systems to improve disaster response. They will also be recommended to take steps to reduce casualties by enhancing drainage to reduce flood risks and by strengthening healthcare, especially in poor areas.

...carbon dioxide – plus traces of other organic molecules – in the plume. This lead to to much speculation about the possibility of life in the ocean. Like Titan, Enceladus is now recognised as one of the solar system’s most likely locations for extraterrestrial life. A recent report of hydrogen in Enceladus’ plume has given that recognition even greater prominence....

The Legacy of Nuclear Power, Part 2

...carbon, all this sort of stuff. And in terms of the nuclear debate in my view, nuclear is probably as an industry ultimately doomed. But I think the point I would want to emphasise above all is that we should not be creating more waste beyond what we know we are already gonna have because we won't know what the inventory is. We won't know how long it is gonna go on for....

Microbes – friend or foe?

...carbon dioxide and water (together with energy needed for the microbes to stay alive). Aerobic respiration is the most efficient way of breaking down organic matter although some compounds in the effluent are not broken down completely. The tanks often contain porous solid materials, on which biofilms can develop, increasing the numbers of microbes and so the efficiency...
