Could we control our climate?

...account of how often each kind occurs. In a single location, over time, the weather might range from freezing cold to swelteringly hot, and from drought to heavy rain. You could record all these aspects of weather over one year – say, daily temperature and rainfall – by drawing a histogram (or a ‘frequency chart’) for each (Figure 1). In each histogram, the height...

Supporting female performance in sport and fitness

...account something like the menstrual cycle, which is where a female’s physiology is going to change as her hormones fluctuate across the cycle. And if you’re not controlling for that as part of your experiment, then the outcomes really aren’t particularly useful. Now, if the researchers have been quite diligent and they are controlling for the time of the menstrual...

Talking about the menopause: symptoms, support and the role of exercise

...account, while aerobic training is still important in menopause, sessions should be kept short (20–30 minutes at most). Indeed, a shorter exercise session at higher intensity is even better. This is why activities like HIIT classes, where the exerciser gets sweaty, out of breath and experiences significantly increased heart rate, may be helpful in menopause. What is...

Introduction to Planetary Protection

...accounted for by the presence of an outer layer of ice, with Europa’s icy shroud discovered by astronomers in the 1950s (Figure 20). It is now known that several of the satellites of the outer planets have an icy surface, but the ice is not necessarily frozen water. In the outer Solar System, although water is usually the dominant component, ice can incorporate other...

Studying mammals: A winning design

...account differences in the size by calculating the volume of oxygen consumed for a particular amount (or mass) of animal. Volumes of a gas such as oxygen, would be measured in millilitres (ml) or, more usually, the numerically equivalent unit, cubic centimetres (cm3), and the mass of the animal in grams (g), or perhaps in thousandths of a gram, i.e. milligrams (mg). In...

Watching the weather

...account for how electromagnetic radiation crosses the empty space from the Sun and stars to the Earth and beyond. On encountering matter, radiation is transmitted, absorbed and scattered to varying degrees, depending on the chemical and physical nature of the matter. For example, the visible radiation in sunlight is certainly transmitted through panes of window glass, but...

Meiosis and mitosis

...account for the ratio of the phenotypes. In fact this is an example of mathematical modelling; the mechanism of inheritance is regarded as equivalent to a mathematical process whose consequence can be calculated by the well-established laws of chance and probability. In the next two questions you are asked to predict the results of some different sorts of crosses using...
