14 Oct 2020: Activity 3 – High Temperature Superconductors and Quantum. Materials Research. 3 High Temperature Superconductivity: Superconductors above 30 K. BCS theory set a limit on the critical temperature that could be achieved by any. superconductor at 30

14 Oct 2020: Solutions to Exercises. Exercise 1: Elemental lead (Pb) has a superconducting transition at 7.2 K. A cuboid sample. of Pb has dimensions (l w h) of (4 0.5 0.5) mm. At 7.5 K the voltage across two contacts. (V+ and V-) was measured to be 3.52 nV when

14 Oct 2020: Activity 1 – Zooming out: nation-states and their borders Political borders separate the territory of one state from the territory of another. There are 194 nation-states in the world today, and there are more than 300 land borders between them,

14 Oct 2020: Activity 2 – Zooming in: how people cross borders This activity invites you to critically reflect on the varied experiences of border crossing encountered by people around the world today. The activity also stimulates reflection about the social

14 Oct 2020: Activity 1 - How does the immune system work? The immune system did not evolve to stop humans carrying out organ transplants. Instead we evolved it over millions of years to stop us being invaded and attacked by a variety of prokaryotic and

14 Oct 2020: Activity 3 - Why is the Major Histocompatibility Complex so important? We saw in resource 2 that fetal trophoblast cells are perilously exposed to the maternal blood and immune system. So why are they not attacked as a foreign invader? Half of the

14 Oct 2020: Activity 4 - How might the mammalian fetus avoid immune attack? If you have read the other three resources for this topic, you will now be aware of the potential problem facing the embryo/fetus. Its trophoblast cells, presumably bearing

18 Oct 2020: Bone Identification Answers:. A – scapula. B – humerus. C – ulna. D – radius. E – carpal bones. F – metacarpal bones. G – phalanges. H – pelvis (composed of ilium, pubis and ischium). I – femur. J – tibia. K – fibula. L –

5 Oct 2020: Activity - Genetic Drift. There are actually two processes by which organisms evolve at the genetic level. One is. through natural selection and you will be familiar with this through examples of antibiotic. resistance in bacteria and industrial

5 Oct 2020: Activity - Continuous Genetic Variation. Throughout most A-level courses, you will be introduced to traits whose variation is. apparently controlled by one or, just a small number of genes. For instance, when you learn. about dominance, you will

5 Oct 2020: Activity - Gene-Environment Interactions. In the previous section, we investigated evolution in polygenic traits. Things get even more. complicated when we consider that the environment itself can influence how genes affect a. trait, causing even

5 Oct 2020: Activity - Heritability. Although the nature vs nurture debate is not a useful way of considering variation, we can. find out how much of the phenotypic variation in a trait is due to genetic causes and how. much of the variation in a trait is due

5 Oct 2020: Activity – Heat generation by brown adipose tissue. Brown adipose tissue is an organ specialized for thermogenesis, or making heat. Brown. adipose tissue plays a role in the overall regulation of body temperature, which is. coordinated by the

5 Oct 2020: Activity – Controlling brown adipose tissue thermogenesis. Scientists have learned a lot about brown adipose tissue by studying mice at cold. temperatures. Read the sections called “Classical nonshivering thermogenesis” and “The mechanism of.

5 Oct 2020: Activity – Therapeutic potential of brown adipose tissue. This activity is a bit different from the rest. Now that you know about white and brown. adipose tissue, it’s time to think about how this knowledge could be applied to treat human.

5 Oct 2020: Activity – Seeking solutions from nature. One way of designing with biomimicry is to start with an engineering problem and brainstorm. creatures or systems in nature that have overcome a similar challenge, as they may provide. a solution. Let’s

5 Oct 2020: Activity – Using Nature to Inspire. Another way of designing with biomimicry is to find a fascinating process or animal in nature. and use its features to inspire a totally new design. Let’s practice with two examples! Challenge 1: You sit

5 Oct 2020: Activity – Biomimicry at work today. Biomimicry is a transdisciplinary field, which means it incorporates knowledge from biologists,. doctors, mathematicians, chemists, architects, physicists, and more. Engineering applies. science and technology

5 Oct 2020: Activity - Molecular Dynamics Simulations. How can we understand what is happening at an atomic or molecular. scale? With computers, of course! In the 1950s, researchers developed methods to study atomic. systems by representing each atom as a rigid
