climate is an emergency

LAST week, Waterloo Bridge near New Scientist’s London office was transformed from its usual melee of buses, lorries, bicycles and cars into a green oasis filled with plant pots, food stalls, bongo-playing sit-in protesters and, briefly, a skateboard park. It is easy to disparage the idealism and other-worldliness that characterised the Extinction Rebellion protests in London (pictured) and elsewhere, or to decry its less peaceable aspects and the disruption it caused to “ordinary” people’s lives. But guess what: we are all “ordinary” people. As revered naturalist David Attenborough was pointing out simultaneously on British TV screens, the times we are living in are less so. Climate change is real – and climate change demands action for all our sakes. It is tempting, too, to modulate that action through the prism of pre-existing…

the age of anti-ageing

HISTORY is littered with the corpses of people who claimed to have found the fountain of youth. So caution is warranted with claims of the imminent arrival of drugs to slow ageing (see page 26). But the field of anti-ageing medicine is now a serious one. A decade ago you could go to conferences and hear outlandish predictions about people living to 150 years old or more, often accompanied by rolling eyes from many scientists in the room. Now the emphasis is no longer on radical life extension, but on ensuring we stay healthier for longer. If this translates into verified drugs, that could presage a medical, economic and social revolution. Keeping at bay the age-related conditions that are now the leading cause of mortality in the developed world will be a…

SpaceX capsule failure A CAPSULE that was meant to allow the US to launch its own astronauts into space again appears to have exploded during tests being carried out on the ground on 20 April. SpaceX, which is developing the Crew Dragon capsule (pictured left), has so far acknowledged only that an “anomaly” occurred. However, huge clouds of smoke were photographed billowing from the test site at the Kennedy Space Center in Florida, and video posted to Twitter seems to show the capsule exploding. The US has had to rely on Russia to get people into orbit since the space shuttle was retired in 2011. SpaceX was leading the race to develop a private alternative. Crew Dragon is designed to carry up to seven astronauts to space and return them to Earth. The same…

viral treatment for brain cancer

PEOPLE with incurable melanomas and brain or breast cancers are to get injections of tumour-fighting viruses. The trial will test the safety of a virus that has been engineered to shrink tumours – an approach that holds promise for a range of cancers, including deadly brain tumours. The idea of using viruses to kill cancers goes back more than a century, inspired by anecdotal reports of some people with viral infections being cured of malignancies. But turning viruses that can infect and kill human cells into a safe and effective treatment that targets only tumour cells has proved tricky. Researchers are making progress at last. In 2015, the US Food and Drug Administration approved the first ever virus-based cancer treatment – a genetically modified herpes virus for advanced melanomas that can’t be completely…

chemists develop greener fertiliser

THERE could finally be a way to make fertiliser without releasing huge amounts of greenhouse gases. If the new method can work on an industrial scale, it could help feed the world’s growing population, while also limiting climate change. Farmers rely on fertilisers to feed their crops. Many of these contain ammonia, but the only way to make it on a large scale is the Haber-Bosch process. The method, which was developed in the 1900s, makes the chemical by combining nitrogen from the air with hydrogen. The process requires temperatures of around 425°C and pressures of up to 200 times normal atmospheric pressure. The energy required to achieve this typically comes from fossil fuels, and the ammonia industry accounts for over 1 per cent of our annual greenhouse gas emissions. To solve this…
