[Editorial] Safeguarding the future of human gene editing

The Lancet - Sa, 18/02/2017 - 00:00
In his 1978 book The Beginning and the End, Isaac Asimov wrote, “The advance of genetic engineering makes it quite conceivable that we will begin to design our own evolutionary progress”. Nearly 40 years ago, the enormous prospect of human gene editing was but a twinkle in Asimov's eye, but today, it has become perhaps the most promising, and controversial, frontier of modern medicine. And indeed, as predicted, one with the potential to potently influence human progress.

[Editorial] Organic food: panacea for health?

The Lancet - Sa, 18/02/2017 - 00:00
This month's vegetable shortages and price increases in the UK were attributed to bad weather in Spain, outlining how important sustainable agricultural policy is to health with the changing availability of food sources. Organic food is embraced by many as part of a healthy lifestyle. Currently, the European Union accounts for 24% of the world's organic land, with the global organic market expected to increase by 2·5 times to US$200 billion by 2020. Whether an organic diet is healthier than a non-organic diet was the subject of a recent report commissioned by the European Parliament reviewing epidemiological, in vitro, and animal studies.

[Comment] Offline: Turning fear into resistance

The Lancet - Sa, 18/02/2017 - 00:00
These are dark times for those who care about human rights. Such people are members of the global elites so reviled by today's populist politicians. They believe in international norms and standards that contradict the current rage against the global. And they see something inherently good about the interdependence of peoples—a view that runs counter to the growing public sentiment for exclusive nationalism. Last week, the High-Level Working Group on the Health and Human Rights of Women, Children, and Adolescents convened for the first time in Geneva, under the leadership of Tarja Halonen (former President of Finland) and Hina Jilani (a distinguished lawyer and human rights activist from Pakistan, and a member of the Elders).

[Perspectives] The mesmerist will see you now

The Lancet - Sa, 18/02/2017 - 00:00
Science has produced some of the world's greatest showmen. The Greek surgeon Claudius Galen used to sever a pig's vocal cords to silence its squealing as one of his favourite public stunts, while the 18th-century experimenter Stephen Gray would suspend a boy from silk ropes to show how the human body conducted electricity as his preferred party trick. By the 19th century, science was firmly established as entertainment. Michael Faraday introduced the first Christmas lectures at the Royal Institution in 1825 to showcase new experiments to middle-class audiences.
