Many of us have wondered at some point about the origin of the Universe: Where did it come from? How will it develop in the future? Does it actually have a start or an end? These questions, fundamentally linked to our very own existence, have sparked interest and excitement of generations of scientists and laymen as well as many science fiction authors and filmmakers.
Three weeks ago a group of scientists (called the BICEP2 collaboration) announced the results of their investigations using a telescope at the South pole targeting traces of the birth of the Universe. Many newspapers coined catchy headlines when reporting the BICEP2 results. The Guardian started it all off with “Gravitational wave: have US scientists heard echoes of the big bang?” and later added “Primordial gravitational wave discovery heralds ‘whole new era’ in physics”. The BBC news website went with “Cosmic inflation: ‘Spectacular’ discovery hailed” and New Scientist published two articles, one headed “First glimpse of big bang ripples from Universe’s birth” and the second titled: “Multiverse gets real with glimpse of big bang ripples”.
Speech synthesis has a long and chequered history, going back at least to the Enlightenment when Wolfgang von Kempelen produced an artificial contraption that could make simple vowel sounds, based on a combination of bellows, a vibrating reed and a leather tube – all mimicking the human sound producing apparatus. The field has come some ways since then, with some visible examples of artificial speech in Stephen Hawking’s popular mechanical voice and more recently the voice of Apple’s Siri and our many satellite navigation units. Closer to home, a group of researchers in Edinburgh have pioneered novel methods for expressive speech synthesis, such as in the products of the University of Edinburgh spin-out company CereProc. This work was covered in an article in The Telegraph, under the provocative title, “How do you teach a computer to speak like Scarlett Johansson?” .

Why is ageing research so important?
As a nation we are ageing rapidly and according to the World Health Organisation the proportion of people aged 60 years and over is growing faster than any other age group in almost every country. One clinical implication of growing older is the risk of experiencing age-related diseases including neurological disorders, dementia and Alzheimer’s disease, type 2 diabetes, various cancers, osteoporosis and other serious conditions. Considerable research has therefore focused on understanding the underlying mechanisms involved in ageing with the aim of leading longer but also healthier lives.
Low fat, high carbohydrate, low carbohydrate, high unsaturated fat, high protein, low glycaemic index……there seems to be never ending advice on what we should and should not eat for optimum health. Often this advice is very contradictory and it is therefore no surprise that the public are generally confused about what they should be eating. The latest addition to this debate is the research on protein intake and cancer which was published in Cell Metabolism and covered by a large section of the media, including this article in the Guardian , under the controversial headline “Diets high in meat, eggs and dairy could be as harmful to health as smoking”.
