The Ebola outbreak of 2014 almost brought the world to its knees, but this crisis has mobilized scientists and researchers, paving the way for new treatments and vaccines. From antibiotics and vaccines to computer programs that predict how viruses will spread, new lifesaving tools will be used to fight a wide range of viruses in the near future, including HIV, influenza, dengue fever, malaria, and a host of other killer diseases.
Our lifespan is increasing by 2.5 years every decade - and a third of all babies born today can expect to live to 100. But living longer can come at a cost. Old age itself brings with it a range of debilitating illnesses, many of which are the result of accumulating damage during our lifetime. Three diseases in particular have become the main killers in the developed world - cancer, heart disease and dementia. But a revolution in bio-medicine is now offering new hope for the treatment of these ailments, and the potential to extend our lives still further. Methods such as gene editing and stem cell therapies are transforming the way medicine can conquer disease today. These extreme frontiers of medicine do, however, also come with a range of ethical dilemmas - when is the right time to try out an experimental technique on a patient? Should we gene edit human embryos? And is it right to use cells from aborted foetuses for medical treatments?
