humanity’s greatest scourge

IN ROME 1500 years ago, a mysterious plague swept through the city. Of the hundreds of children killed, one was buried in a cemetery on the outskirts of the city. In 2001, her body was exhumed and autopsied using modern genetic techniques. The tests showed she had died of malaria – the earliest confirmed case of a disease that has been with us since time immemorial. Malaria may have killed perhaps half of all the people who have ever lived. For most readers of this magazine, however, it is a distant scourge, perhaps recalled only when ordering medication for an exotic holiday. Such forgetfulness is neither justified nor wise. In 2018, malaria infected 219 million people, and killed around 435,000. Most of those who die are children under 5, mostly in sub-Saharan…

measles resurgent in uk

FOLLOWING 231 confirmed cases of infection in the first three months of the year, the UK has lost its measles-free status with the World Health Organization. Prime minister Boris Johnson has called for health leaders to renew their efforts to ensure that 95 per cent of people have had two doses of the measles, mumps and rubella (MMR) vaccine. The World Health Organization recommends that 95 per cent of people need to be vaccinated against measles to achieve herd immunity, which stops the infection spreading through populations. Recent figures suggest that only 87.2 per cent of UK children have received the second dose. “Measles is one of the most infectious diseases known to man – only one person travelling back to an area with lower vaccination rates can lead to an outbreak,” says…

moss-covered walls installed to clean city air

WALLS blanketed in moss are popping up in major cities, along with promises that they can help reduce air pollution – but can a few square metres of plant matter really tackle the smog? Berlin-based Green City Solutions believes so. Its moss walls, called CityTrees, are about 4 square metres in size. It says they can filter up to 80 per cent of pollution particles out of the air, including the tiny ones linked to respiratory and cardiovascular diseases. The walls collect rainwater, which is pumped through an irrigation system to the plants, powered by solar panels. These also drive fans to increase airflow through the plants. As a result, the firm says its product filters 3500 cubic metres of air an hour, which is equivalent to the total volume of air…

suspicious organ studies retracted by journals

FIFTEEN studies about transplanted organs by researchers in China have been retracted due to concerns the work may have used organs from executed prisoners, according to the website Retraction Watch, which monitors questions raised over published research. China’s government said in 2015 that the nation had stopped using organs from executed prisoners, which is illegal under international conventions. But campaign groups and some doctors suspect the practice continues, particularly involving prisoners of conscience. Some claim that targeted groups include Uighurs, a Muslim ethnic minority in China, and practitioners of Falun Gong, a belief system similar to Buddhism that has been outlawed. Various journals that publish research into organ transplants have previously said that, for ethical reasons, they won’t publish any work that used prisoners’ organs. Yet earlier this year, campaigners highlighted 400 published…

proof of parallel universes?

SOME ideas about the quantum world seem to suggest that there are many versions of you spread out across parallel universes. Now, two researchers have formulated a proof that attempts to show this is really true. The proof involves a fundamental construct in quantum mechanics called Bell’s theorem, which deals with situations in which particles interact with each other, become entangled and then go their separate ways. It is what is called a “no-go theorem”, one designed to show that some assumption about how the world works isn’t true. Bell’s theorem rests on three assumptions. First, that there is local causality, meaning that objects can only affect what is near them and an effect must happen after its cause. Next, events aren’t all predetermined by some external force. The last assumption is…
