2.1 Institutional science promotion events

Nowadays, engaging with science through an institutional science promotion event can be quite straightforward. You can find out about such events by, for example, reading posters in your local library, watching a science documentary on TV or browsing the internet. The range of such outreach events is remarkable – from long-standing mainstream programmes such as the Royal Society Christmas lectures on TV and the annual BA (British Association for the Advancement of Science) Science Week, to

5.5 Summary of Section 5

When oestradiol combines with its receptor inside neurons, the cell produces proteins which protect it from cell death. As a consequence, the male brain, which has oestradiol in its neurons in early life, becomes different from the female brain, which does not have oestradiol in its neurons. Retinoic acid is needed in high concentrations to produce those proteins associated with posterior structures of the embryo, whilst retinoic acid is needed in low concentrations to produce those proteins

#394: What's killing women? Sex disparity and the shifting landscape of age-related disease

Population health researcher Professor Cassandra Szoeke outlines what ails women as they grow older, how men differ from women in age-related diseases, and how public awareness and personal lifestyle change have been shown to have a positive impact on women's quality of life in their later years. Presented by Dr Andi Horvath.

The histone proteins

The genes for the histone proteins are very highly conserved across eukaryotes, reflecting their importance in DNA packaging. The histone family consists of five groups of proteins, histones H1, H2A, H2B, H3 and H4. An examination of their amino acid content gives us clues as to how the histones fulfil their role in DNA packaging. Rather like the polyamines in bacteria, these proteins are highly positively charged, with up to 20% of their amino acids being lysine or arginine, the charged side

2.6 Connecting and splicing fibres

There are two different types of fibre joint that need to be considered: permanent splices (the equivalent of soldered or crimped connections on copper cables) and demountable connectors.

Splices are used along a route to allow a link to be built up from convenient lengths of cable. The lengths are typically 2 km. Fibre is manufactured in lengths longer than this, but, once put in a cable, lengths longer than 2 km are difficult to transport and lay. Splices are also used t

4 Status citizenship

All these organisational initiatives are deeply concerned with labour conditions and the notion of the ‘working citizen’. And their activities raise the issue of status citizenship and the role of legal sanctions. The forms of commitment by firms and their monitoring by the organisations just outlined are voluntary on the part of companies. One of the problems with the emphasis on acts citizenship in the debates about GCC is that the question of status citizenship is largely

Un-PC Lego Making Toys Girls Like

Lego — the company that makes stackable toy bricks — has become a toy powerhouse in recent years, even surpassing Mattel in toy sales during 2014. Lego has become so popular, in fact, that the company has problems avoiding “brick shortages.”

Lego’s success has been helped along by the fact that — finally — Lego has managed to find success with girls.

With the launch of the Lego Friends line, Lego has tapped into 50 percent of the child pop

3.6 Protein kinases

Protein kinases phosphorylate proteins either at tyrosine residues (tyrosine kinases), or at serine and threonine residues (serine–threonine kinases), or on any of these three amino acids (dual-specificity kinases). All these activities are employed in signal transduction pathways (histidine kinases also operate in certain plant and bacterial pathways, but not in animals). You should now be familiar with receptor tyrosine kinases, and have seen in some detail how phosph

3.7 Protein phosphatases

Together with inositolphospholipid phosphatases, protein phosphatases are key regulators of signal transduction pathways. Like protein kinases, protein phosphatases are either tyrosine phosphatases (the majority of protein phosphatases, some of which are shown in Figure 44) or serine–threonine phosphatases (including the phosphoprotein phos

6.3.3 Photomultiplier tubes and detection circuitry

The visible photons are collected by an array of photomultiplier tubes behind the crystal. These convert each visible photon to an electron and then multiply the number of electrons sufficiently to give a voltage pulse. Because the number of visible photons is proportional to the energy of the incoming gamma ray, the height of the pulse depends on this energy. This gives a method of counting the numbers of gamma photons at different energies that reach the crystal.

1.8.1 Making and using field sketches

How do we start to make sense of a rock exposure? Drawing a sketch is one of the best ways to start, as it forces you to notice many aspects of the exposure. It also helps you to build up a picture of which aspects are significant and which are incidental or even irrelevant to a geological study. The aim of a field sketch is that it provides a record of your observations (along with notes taken at the same time, and also perhaps a photograph to record details). A sketch is complementary to a

2.1 Structure and function of the outer and middle ear

Figure 1 is a diagram of the human ear. The outer ear consists of the visible part of the ear or pinna, the external auditory canal (meatus), and the tympanic membrane (tympanum) or eardrum. The human pinna is formed primarily of cartilage and is attached to the head by muscles and ligaments. The deep central portion of the
