Over the past few weeks, in collaboration with a group of Block 3 Outdoor Work students and the Sustainability Group, we have begun the huge task of cataloguing the school’s biodiversity.
We started with the Lake, where we discovered 28 different species of freshwater animals, including water boatmen, dragonfly and damselfly nymphs, whirlgig beetles and flatworms. A walk around the centre of the site revealed 38 species of tree and 19 birds, such as the green woodpecker and nuthatch. The use of a moth trap also showed there were 14 moth species in the wildlife garden behind the Science department, which is remarkable, considering it is late in the year.
To fend off the global warming crisis, we need to appeal to the hottest place on earth. The sun’s core is 10 million degrees, but in the Joint European Torus (JET) at Culham, the doughnut-shaped plasma in the reactor consistently reaches temperatures of over 100 million degrees to initiate nuclear fusion between hydrogen isotopes and release enormous quantities of energy. The hydrogen is sourced from seawater, and there are no harmful waste products. What is not to like? Unfortunately, it’s fiendishly difficult to achieve.
The Sixth Form physicists visited JET last week, for an inspiring tour and lectures. The scientists and engineers explained the current developments of this futuristic technology, which has come a long way since its inception in 1983, and has inspired the next generation of fusion reactors, driving the plasma science and fusion research. Ground-breaking and innovative engineering solutions are necessary for the magnetic containment, keeping the super-heated plasma just metres from the surrounding vacuum at almost zero, to harness this potentially limitless resource.
Biologists in 6.1 travelled to the Apollo Theatre in London to hear a series of lectures by some of the country’s leading scientists as part of A Level Biology Live.
First was 2009 Nobel Prize winner and President of the Royal Society, Professor Sir Venki Ramakrishnan (pictured above), whose many scientific contributions include his work on the atomic structure of ribosomes. Ribosomes exist in their millions in every cell, and are the site where genetic information is read to synthesise proteins from amino acids. He began work on ribosomes in the late 1970s and eventually discovered their complex three-dimensional structure in 2000, with the aid of X-ray crystallography.
Next, Professor Robert Winston – who was the Bedales Eckersley Lecture speaker in 2013 – spoke about manipulating human reproduction, from his work in vitro fertilisation, through to regenerative medicine such as stem cell research and epigenetics, which may turn out to be the most important biological development in the years to come. However, he warned that manipulating the human will always be dangerous, uncertain and unpredictable.
