A (fairly) light-hearted explanation of the process of in vitro fertilisation in humans. Winner of the Kroto Prize for Innovative Use of Technology in Science Learning 2016.

Matt Johnson explains the Krebs Cycle, its discovery by a University of Sheffield Nobel Prize winner and its role in endurance sports such as cycling.

The quantum spin Hall effect is a topological state of matter characterized by sustaining gapless chiral edge states together with an insulating bulk. This phase can be triggered out by applying strong magnetic fields in a graphene sample

A magnetic tunnel junction is a device with two magnets separated by a very thin non-magnetic barrier. The two magnets can be aligned parallel or antiparallel. The electrical resistance of this devices depends on the alignment. This video illustrates....

It seems likely that C60+ will act as a stable site for a wide variety of adducts and that these entities will contribute to the Diffuse Interstellar Bands.  John Maier's group in Basel is looking for species like C60(Fe)+.

The early (mid 1990s) work on the electronic spectroscopy was carried out by John Maier's group, trapping C60+ in a neon matrix in this apparatus.

John Maier's team at the University of Basel solved the riddle of C60+ in 2015.  In this brief view Colin Byfleet looks at the unique apparatus used in John's work.

The presentation the solution to this long-standing puzzle occurred at a most serendipitous moment.  John Maier, Professor of Physical Chemistry at the University of Basel reveals the momentous details.

John Maier, Professor of Physical Chemistry at the University of Basel, describes the journey from the prediction of C60+ in 1987, through tentative assignment of its electronic spectrum by Radioastronomy, measurement in a neon-matrix and finally, in....

Rosie Bolton describes the importance of this huge project and some of the interesting problems which needed to be solved in its planning and implementation.

Ian McKellen speaks at FSU about his acting career and some of the fascinating things that he has learned through theater and personal experience.

Naresh Dalal is interviewed by Harry Kroto about his eventful life in Chemical Physics.

Kant, in possibly his most celebrated essay, defined the Enlightenment as: Man’s emergence from his self-imposed period of immaturity. This immaturity is the inability to use one's own understanding without another's guidance. Without the freedom t....

Mark Hindmarch talks about our understanding of how we explain the immediate aftermath of the Big Bang.

Roy Darlington explains the attractions of the remarkably simple Stirling engine

Jonathan talks to a real exoert about the science of balance.

What is there in your computer which is attractive to bacteria and fungi?

Norman Billingham talks to Jonathan Hare about the science and ethics of preservation and conservation.

Jess describes her route into Chemistry

Sussex University has always supported unusual, interdisciplinary and innovative faculties. A good example of this was the Nitrogen Fixation Centre. Jeff Leigh was part of this exceptional work who's aim was to discover how nature uses nitrogen to cr....

Children's Buckyball Workshop in San Luis Potosi Mexico with Harry Kroto organised by Humberto and Mauricio Terrones. This group started a trend balancing Buckyballs on their heads. I hope the music background is acceptable as no one is making money ....

Come share with me the memories of where ideas have come from during my life - from childhood to old age. You may find it helpful in encouraging your own brains to come up with new ideas. They won't all be useful - as I have found in this case of min....

Before the 1970s, well fixed specimens of gastric mucosa were rare. Then the flexible endoscope was introduced. This enabled gastroenterologists to take numerous well-fixed small biopsies from the stomach. Gastric histology and pathology were clearly....

Telomeres protect chromosome ends and help stabilize the genome. Throughout human life and in aging, telomeres often erode down, eventually causing cells to malfunction or die. The highly regulated cellular enzyme telomerase adds telomeric DNA to tel....

Immune surveillance by virus-specific CD8+ cytotoxic T lymphocytes (CTLs), or killer T cells, has long been known to be central to the control of acute infections and some cancers, though the role of CTL memory in the rapid recall of immune protectio....

In 2010, we chemically synthesized the 1078 Kb Mycoplasma mycoides genome and transplanted it into a recipient cell cytoplasm to create a 'synthetic cell', JCVI-syn1.0 (Science, 329, 52-56, 2010). We identified several hundred non-essential genes by ....

Nitric oxide research has grown rapidly with about 150,000 research publications describing its biological effects. It is an important messenger molecule that affects most tissues and biological processes. Many effects of nitric oxide are mediated by....

The concept of bioelectricity emerged in the late 18th century, based on the experiments of Galvani and Volta. Sixty years ago, Hodgkin and Huxley showed that the nerve impulse is a result of permeability changes of the nerve membrane. This raised th....

The complexity of modern biological life has long made it difficult to understand how life could emerge spontaneously from the chemistry of the early earth. We are attempting to synthesize simple artificial cells in order to discover plausible pathwa....

Reversible protein phosphorylation can be considered one of the most prevalent mechanism by which eukaryotic cellular events are regulated. It is directly involved in numerous pathological conditions, and bacterial and viral diseases. This process wa....

Conservation laws are very important in quantum physics. Two examples of applications will be given. First, optical pumping which uses transfer of angular momentum from polarized photons to atoms to produce highly polarized atomic gases. Then, laser ....

When Monsanto first tried to introduce GMO seeds into Europe there was a backlash by the Green parties and their political allies, who feared that American agro-business was about to take over their food supply. Thus began a massive campaign not agai....

Beginning with an exception to normal function caused by a genetic aberration, one may hope to find at least one protein with non-redundant function in a certain biological process. This approach permitted the identification of the receptor for bacte....

Both evolutionary biology and genetics have their roots 150 years ago in work with phenotypic variants of plants and animals. In contrast, microbial genetics originating as recently as the 1940s, rapidly revealed that filamentous DNA molecules are th....

The diagnosis, classification, and treatment of human cancers are being transformed by scientific discoveries that were strongly influenced by the discovery of the c-src proto-oncogene, as described in the lecture by Michael Bishop. The path to this ....

Our Universe was created in 'The Big Bang' and has been expanding ever since. Brian Schmidt describe the vital statistics of the Universe, including its size, weight, shape, age, and composition. He also tries to make sense of the Universe's past, pr....

Metrology - the science of measurements - is responsible for the international uniformity and precision in standards. Today, the seven units for meter, kilogram, second, ampere, kelvin, mole, and candela of our international system of units (SI units....

Several laser-based Atomic Clocks now have an accuracy potential of ~2 x10-18, a hundred-fold better than the best achieved after more than 60 years' experience with rf resonances in Cs atoms. Still, this long attention span documents that the Cs Fou....

Because of the following statement from the American Physical Society: “The evidence is incontrovertible: Global warming is occurring. If no mitigating actions are taken, significant disruptions in the Earth's physical and ecological systems, s....
